What do people think of democracy around the world? And does it matter?

(Warning: A long and rambling graph-heavy post on public opinion by someone who has never worked with public opinion data before, and who is in addition very skeptical about the importance of public opinion for large-scale institutional outcomes. Part of this occasional series).

I’ve been playing around with the data from the latest wave of the World Values Survey, trying to figure out what people think of “democracy” in these large-scale surveys, and whether it is related to any large-scale institutional features of political systems. And I must say, I find public opinion about democracy quite puzzling.

It’s not that people don’t like democracy. On the contrary, public opinion surveys like the World Values Survey or the various regional “Barometer” polls (Latinobarometer, Arab Barometer, Asian Barometer, Afrobarometer) tend to consistently find that people really like the idea of democracy; asking about democracy is like asking about motherhood. Consider the figure below, which plots the range of responses in the sixty countries surveyed by the WVS at various times between 2011 and 2014 to a question asking about people’s opinion of “having a democratic political system”:

In most of these countries (including many countries most people would classify as “authoritarian”), more than 75% of the population says that having a democratic system is a “very good” or a “fairly good” idea, while only small minorities claim democracy is a “very bad” or a “fairly bad” idea. In the modal country, in other words, large majorities are “pro-democracy” in some abstract sense. Nevertheless, these same majorities are not always very discriminating about what they consider “good” political systems. In some countries, large numbers of people agree both with the idea that democracy is a good form of government, and that having the army rule, or having a strong leader “that does not bother with parliament and elections” is also a good thing.

The figure below compares answers to the question of whether respondents consider “having a democratic system” a good idea with their answers to questions about other modes of political decisionmaking. It is ordered according to whether the pattern of responses in a country is similar to that found in New Zealand (the first country at the top left). New Zealand is a good reference country because (besides the fact that I live there) the pattern of belief in NZ is consistently “pro-democracy”: democracy is considered to be good by large majorities, while army rule, expert rule, and strong leader rule are not so considered, though expert rule is not altogether discounted.[1] Many countries display a similar pattern of responses (not just “Western” countries; see, e.g., Thailand, where democracy is greatly preferred to army rule or expert rule, even if a substantial minority does evaluate these alternatives positively, reflecting Thailand’s persistent political conflicts), but in others views are more confusing. For example, majorities of people in India, Mexico, and Egypt seem to think all political systems are a great idea; army rule, democracy, expert rule, it’s all good.[2]

Indeed, about 36% of all respondents in India give positive evaluations (answers of “very good” or “fairly good”) to all hypothetical political systems, while less than 1% of respondents are what we might call “principled democrats,” evaluating democracy positively while negatively assessing the remaining options, as we can see in the figure below.[3] By contrast, around 47% of respondents of respondents in Sweden are “principled democrats,” while only around 4% are what we might call “enthusiasts about everything.” (I’m not sure why people in India seem to be so enthusiastic about all the options here; perhaps this is some weird survey artifact. Readers from India might help me out here?).

The WVS also asks a number of questions about whether people consider various things “essential” to democracy, ranging from classic liberal ideas (free elections, equality under the law, civil rights) to economic and social outcomes (income equality, unemployment help, progressive taxation), to “antiliberal” ideas (“religious authorities interpret the laws,” “army takes over if the government is incompetent”). And though many people all over the world tend to agree that elections and other liberal freedoms are essential to democracy, there are clear differences in public opinion about what other things they also consider essential. The figure below is again arranged with New Zealand at the top, followed by those countries whose pattern of responses is most similar to New Zealand:

Public opinion about democracy in the countries at the top of the figure is recognizably “liberal”: free elections, women’s rights, and civil rights are seen as pretty important to democracy by large numbers of people, while economic equality and social security are seen as less important, and “antiliberal” ideas receive little support (though not zero support! One gets the impression that some respondents are just trolling the interviewers, but who knows; survey respondents are under no obligation to be consistent). By comparison, public opinion about democracy in Russia or Kazakhstan (and in most of the post-Communist countries in the sample) tends to emphasize economic equality and social security more (though civil rights and free elections remain important), while in Yemen or Pakistan just about everything in the list is seen as essential to democracy (including antiliberal ideas), and in Bahrain just about everything is seen as unimportant (another puzzling pattern!).

Aggregate public opinion conceals much variation among individual responses, of course. We might think of individual responses as divided into different types, depending on how much they emphasize different ideas – liberal, egalitarian, and antiliberal – relative to some baseline when answering questions about what ideas they think are “essential” to democracy.[4] In particular, we can distinguish between relative liberal democrats (people who consider free elections and individual rights more important than the average respondent in all countries, while de-emphasizing egalitarian and antiliberal ideas), relative social democrats (people who associate both liberal and “economic” ideas with democracy), relative egalitarian democrats (people who associate democracy primarily with “economic” ideas), antiliberals (people who associate democracy primarily with anti-liberal ideas, like “the army takes over when the government is incompetent”), antiegalitarians (people who associate democracy with everything except economic equality), enthusiasts (people who associate democracy with everything), and refusers (people who do not think any of the options on offer in the survey is especially essential). The figure below is ordered according to the percentage of respondents who express relatively liberal and liberal egalitarian views of democracy:

Perhaps unsurprisingly, large numbers of people in “Western” countries – Germany, Sweden, New Zealand, etc. – express views of democracy that are “liberal” or “liberal egalitarian” (relative to the world average), though proportions of “principled” liberals and “egalitarian” liberals vary (Germany contains a very large number of “egalitarian” liberals; New Zealand and the United States do not). Overall, however, pure liberal views are relatively uncommon; indeed, in some countries (Bahrain, South Africa) there are basically no detectable relative liberals (egalitarian or otherwise), while in many countries (e.g, Qatar, Iraq) large numbers of respondents emphasize both economic equality and anti-liberal ideas as essential components of democracy. This is not to say that in these societies nobody cares about free elections or civil rights; but many people there appear to see no contradiction between thinking that free elections and civl rights are important to democracy (even if not the most essential thing), and thinking that democracy also involves (perhaps more essentially) having a role for religious authorities in politics, or for the army when the elected government appears to fail.

Some variation is to be expected given that people in different countries may use different baselines when asked to rank ideas along a 1-10 scale (what a “ten” means in Sweden may not be the same as what it means in Bahrain, on average), but still, the differences are striking, and suggestive of “cultural” clustering among conceptions of democracy. And indeed, using a simple graph representation of the similarities between patterns of responses among countries,[5] and a community discovery algorithm, we find between 3 and 7 clusters (depending on the algorithm used), one of which typically corresponds to the “Western” countries plus Japan and South Korea, and another to the Post-socialist world (Soviet countries plus China plus a few others). For example, the figure below displays five clusters, arranged by color according to the average similarity of the conception of democracy of countries in the cluster to New Zealand; the labels in the legend show a representative country in the cluster.

The countries in the dark blue group (labeled “New Zealand”) show “liberal” patterns of responses, and contain most of the “Western” democracies, plus Japan, South Korea, and Uruguay. The countries in the orange (“Russia”) group contain most of the post-socialist countries, plus a few others (Egypt, Malaysia). Countries in light blue comprise an “Iberoamerican” cluster (Spain plus Argentina and Chile) that is pretty similar to the “Western Europe” cluster; countries in dark red are pretty similar to the post-socialist countries, though they tend to have more “illiberal” conceptions of democracy. One could easily tell a story here about how socialization in formerly communist countries tended to associate democracy with the egalitarian values of the socialist project, which, though denied in practice in some ways, seem to have been accepted by the vast majority of the population. And a contrasting story could be told about the “Western” conception of democracy, which more strictly separates egalitarian “outcomes” from democracy as such. I am less sure about the other, more illiberal clusters; I suppose one could tell a story about the importance of “religious authority” in some of them, but it certainly would not fit all countries. Perhaps the most obvious feature of the “Cyprus” (light yellow) and “Peru” (dark red) clusters is that they seem to gather many the countries of what was formerly called the “third world,” which suggests a better division into “first,” “second,” and “third” world conceptions of democracy. These conceptions, though not wholly distinct, do suggest that people’s views of democracy were shaped in some indirect way by both development patterns and the great ideological conflicts of the 20th century. People expect different (and sometimes contradictory) things of democracy in different parts of the world; and these expectations appear to have been partly shaped by the institutional history of their societies.

Nevertheless, there is little direct correlation between public opinion about democracy (“democratic values,” if you will) and “actual” measures of democracy (as devised by political scientists). Ronald Inglehart (one of the principal investigators for the WVS) has argued that the number of people who “like” democracy or find it important for their country is essentially uncorrelated with standard measures of democracy (he uses Freedom House, but the point holds for other measures, like Polity IV). Talk is cheap, and “liking” democracy has little to do with “having” a standardly democratic political system. Instead, he suggests, democracy is associated with what he and his collaborators call “post-materialist” values.

Inglehart is certainly right about the lack of correlation between “liking” democracy (or even considering it important) and standard measures of democracy (as we can see below); but though the measures of post-materialism included with the WVS do show some correlation with standard measures of democracy, this is not always very high. The percentage of people who give “liberal” answers to questions about the essential characteristics of democracy (relative to the world average) displays a higher correlation with “standard” measures of democracy than almost anything else, including “post-materialist” values:

I do not think this says much about whether a certain combination of views about democracy is needed to produce or sustain democracy; more likely, the process of socialization in countries with “consolidated” liberal democratic institutions, like New Zealand, more clearly differentiates “democracy” from other alternatives, and more clearly associates it with a specific constellation of institutions, than elsewhere, where democracy might be a bit of an empty signifier, ready to be filled with whatever content political entrepreneurs manage to pour into it. In other words, I find it more plausible that liberal democratic institutions tend to produce liberal democrats than the reverse. I also do not find Inglehart et al.’s argument for the importance of post-materialist values to the long-run stability of democracy convincing; though there is certainly a correlation between these post-materialism indexes and some measures of democracy (not all), some careful statistical work suggests the relationship goes away when using other measures of democracy and accounting for reverse causation (from institutions to values). The sorts of aspirational values that get expressed in surveys (which may not be ultimately reflective of deep commitments to defend or promote certain institutions) seem more likely to be shaped by institutions than the other way around; but perhaps that is only my prejudices speaking.

One piece of evidence for this “primacy of institutions” thesis, it seems to me, is the general lack of correlation between responses to questions about the actual degree of democracy in a respondent’s country and standard measures of democracy. “Expert” and “popular” assessments of democracy often diverge radically, suggesting that what people come to consider “democratic” is shaped by prevailing regimes more than the other way around:

Again, these differences are not altogether surprising; different people will answer “rating” questions like these from different baselines, and their responses may anyway be affected by such factors as how well they think the country is doing, what political events are in the news, and perhaps even their mood or the weather at the time of the interview. Someone with more time and training than me could probably figure out how to calibrate these responses better. Yet there are still some interesting patterns worth noticing. For example, there seems to be something of a “sour grapes” effect: in some countries where people rate the level of democracy lower, they also tend to give lower average answers to the question of how important it is that their country be ruled democratically. Moreover answers about more specific aspects of political life, such as the quality of elections, tend to be reasonably well correlated with standard measures of democracy; people in Rwanda, for example, are surprisingly upbeat when they answer the question of how democratically they think their country is ruled (perhaps due to the successes of Rwandan economic development under Kagame), but (on the aggregate at least) they have fewer illusions about their electoral process, which they accurately judge is hardly a perfect model of fairness. (The one obvious outlier is Singapore, where people express great confidence in the freedom and fairness of their elections while being given a low FH/Polity2 score).

The specific answers to questions about elections are interesting in themselves (it’s too bad it was only asked in 40 out of the 60 countries in this wave of the WVS). The figure below is arranged from “freest” to “least free” (by the total Freedom House score), starting with Australia and Chile:

Countries at the very top display high levels of trust in elections: most people think votes are counted fairly, election officials are fair, voters are given a genuine choice at the polls, opposition politicians are not prevented from running, there’s little violence at the polls, and media coverage is reasonably unbiased. (The Netherlands and Germany are model countries here; people there really trust in their electoral process!). As we go down the list, however, we find countries where trust in the voting process is mingled with distrust at the media and the rich (e.g., Taiwan and Brazil), and eventually countries where opinion is highly polarized (e.g., Pakistan, Zimbabwe, Egypt, or Nigeria, where significant numbers think votes are counted fairly and significant numbers think they aren’t). Only in a few countries do we find something like a generalized distrust of the electoral process by majorities of those surveyed; more usually, different groups in the population fiercely disagree about the fairness of the electoral process (as in Venezuela today – unfortunately not included in this WVS wave).This is one more reason to think that elections do not necessarily “legitimate” governments; if half your population strongly doubts their fairness, and the other half strongly supports it, the election is going to be experienced quite differently by each side.

The nine items on elections in the survey measure, as far as I can tell, four dimensions of the electoral process: fairness of the election itself (electoral officials are fair, votes are counted fairly, voters are threatened with violence at the polls); fairness of the media (TV news coverage, journalists); extent of choice (voters are offered a genuine choice, opposition politicians are prevented from running); and perceptions of problematic money in politics (voters are bribed, rich people buy elections). We can thus use an index of perceptions of the fairness of each of these components of the electoral process to construct a measure of polarization. The figure below is thus arranged according to one such measure, from the most polarized society (Zimbabwe, where the fairness of every component of the electoral process appears to be fiercely disputed, with approximately equal numbers of people trusting and distrusting each of them) to the least polarized (Germany, where there seems to be great consensus that every component of the electoral process is fair):

Perhaps the most striking thing we can observe in this graph is how much people distrust the media’s political role in most societies; almost everywhere the media component has the largest number of people expression reservations about its fairness during elections. And people in many societies generally considered to be democratic (e.g, Peru, Argentina, South Africa) express much distrust of almost every component of the electoral process; in Nigeria there almost seems to be a general consensus that everything about the electoral process is unfair. Yet there is a strong correlation between the degree to which perceptions of election day fairness are polarized and the degree to which the country has been democratic, by conventional measures; we might say that the mark of a consolidated democracy (by conventional measures) is simply that people in general agree that election day is “fair,” regardless of other disagreements:

Indeed, the more agreement there is on election day fairness, the higher people rate the degree of democracy in their country:

If I may speculate here, elections only seem to legitimate governments – ensuring some degree of institutional stability – when people already agree that they are fair. They do not have any magic “legitimating” powers if people do not already agree on their fairness; and whether people agree on the fairness of elections is only in part a function of their objective fairness. Deep conflicts in society may “spill over” to the fairness of elections.

All code for the figures in this post is available in this GitHub repository. You will also need the World Values Survey data file (sixth wave, 2011-2014), and the latest data from Freedom House (helpfully converted into an R-friendly CSV file by Jay Ulfelder here).

  1. For the details of how the measure of similarity was calculated, take a look at the code for this post. Essentially, I created a matrix of the proportions of the population giving each answer in each country, and used a Gower distance measure to calculate which countries were similar to which.
  2. Egyptians weren’t asked about army rule in 2013. Perhaps the question was regarded as too politically sensitive in the circumstances.
  3. The figure excludes Egypt, Morocco, and Qatar, where some of these questions weren’t asked. There’s a fair amount of non-response to these questions in many countries; that’s the reason why the bars in the figure don’t go all the way to the right hand side.
  4. This can be done in different ways, but below I simply categorize a response as emphasizing one of these ideas if it scores higher than the world average for the relevant items. More precisely, I combine the scores for the three items measuring each of the main ideas, and categorize a response as emphasizing that idea if it this number is larger than average across all countries. “Liberal” ideas are measured by the questions asking about how essential women’s rights, free elections, and civil rights are to democracy; “egalitarian” ideas are measured by the questions asking about how essential income equality, state provision of unemployment benefits, and taxation of the rich and subsidies to the poor are to democracy; and “antiliberal” ideas are measured by the questions asking about about how essential obedience to the state, the army taking over if the government is incompetent, and a role for religious authorities interpreting the laws are to democracy. All of these are, of course, highly imperfect as measures of these ideas; but this is in the nature of large-scale survey research.
  5. A weighted undirected graph where edge strength is the measure of similarity between any two countries in their response patterns to all of the nine questions concerning the essential characteristics of democracy. See the code for this post for more details on its construction.

Principal-agent problems in the Soviet Union, circa 1990

Widespread fictitious economic accounting was foiling planners to the point that the KGB employed its own spy satellites to ascertain the size of the Uzbek cotton harvest, but the spy agency itself suffered from internal falsifications.

Electoral Parodies

I've been reading a lot about various dictators this summer. And again and again I am struck by the existence of what one might call “electoral parodies” in many dictatorships: abuses of electoral rules and standards so blatant and obvious that they cannot be interpreted as anything other than mockery. Here is a good example, from the Dominican Republic:
In 1941, as the new ally of the United States against the Axis Powers, Trujillo felt obliged to extend the democratic facade by creating an opposition party, and so the Trujillo party was formed. But Trujillo was the presidential candidate of both the new creation and his old official party. Under the Trujillo Party banner, he received 190,229 votes and as the candidate of the Dominican Party he polled 391,708; the total of both parties, 581,937, meant that Trujillo had again received 100 per cent of the vote (Wiarda, Dictatorship and Development: The Methods of Control in the Dominican Republic, p. 66.)
Others include such things as releasing the results of the election before it takes place, receiving 100% of the vote from more than 100% of the voters (another Trujillo specialty), declaring victory while failing to announce any vote totals, and so on. But my all-time favorite is this story, from Haiti. François “Papa Doc” Duvalier had been first elected to the Presidency in 1957 for a six year term in a rigged but reasonably competitive election, and had since consolidated his power. On 30 April 1961, there was a scheduled congressional election. Although Duvalier was not supposed to be on the ballot,
[f]ew voters considered it unusual that the name Dr François Duvalier was printed at the bottom of each and every ballot … Late that evening rumour spread that Duvalier – with two years to go on his current term – had declared himself reelected for an additional six years because his name had appeared on the ballot. On 4 May Attorney General Max Duplessis declared to the Electoral Board – called the Census Committee – that Duvalier indeed had been voted another term in office. Crowds were organized to collect before the palace and applaud this view. … … In three days the Census Committee convened, agreed, declared President Duvalier re-elected, and announced that he received more than 1.3 million votes … … The new legislature ratified the election (14 May 1961), and Duvalier responded: ’I accept the people’s will because being a revolutionary I do not have the right [not? sic] to hear the people’s voice (Diederich and Burt, Papa Doc: Haiti and its Dictator, pp. 169-170)
The sheer chutzpah of this “election” is a thing of beauty. Voters voted Duvalier into office without realizing that they had done so! He wasn’t supposed to even be up for election!

I’ve written before about elections without choice, but this stuff still fascinates me. Clearly, much of what is going on in these “elections” is about signaling – showing who is boss by doing something outrageous and getting away with it – but I am struck by the degree to which people who should know better still interpret them as somehow “legitimating” performances. There is something like a “third person effect” going on here, as if analysts thought that electoral parodies must have a greater impact on gullible others than they do on themselves. Yet electoral parodies are not “democratic facades” that legitimate regimes in the eyes of ill-informed citizens or commentators from abroad, but “democratic burlesques” that ridicule any possible standards of democracy, and are clearly experienced as such by most citizens and international audiences.

The Duvalier case is especially interesting, since it is so absurdly brazen, and if anything contributed to the “delegitimation” of the Duvalier regime in the eyes of international audiences. Unlike in the Trujillo case noted earlier, the “re-election” of Duvalier did not come about because of pressure from abroad; in fact the US did not know it was going to happen, and made it clear through its ambassador (the aptly-named Robert Newbegin, who was supposed to inaugurate a new era of Haitian-American relations after the expulsion of the previous American Ambassador, Gerald Drew, in 1960) that it considered it illegal. As the end of Duvalier’s original term approached in 1963, the US even put out the message that it would welcome a military coup to oust him, since it considered Duvalier’s legal term to be over. (Though various ineptly planned coup attempts and a number of poorly executed invasions from the Dominican Republic did take place over the next few years, Duvalier survived them all. The man was lucky, and his opposition was almost comically disorganized.) Most other nations in the Organization of American States, though generally reluctant to intervene in Haiti, agreed that Duvalier was an embarrassment, and his “re-election” a sham.

Worse, not only did Duvalier further strain his (already strained) relations with the US by insisting on his “re-election,” but he did not even gain any of the benefits of normally rigged elections, like (biased) estimates of opposition or government strength, or the ability to make a more or less plausible claim of popular support, since nobody knew that he was going to be on the ballot; it wasn’t supposed to be a presidential election! From the point of view of contemporary analysts, it looked like an unforced error; why couldn’t Duvalier just have waited for two years to steal the next scheduled presidential election in a proper way? It’s not as if Duvalier had no genuine supporters; the “quiet doctor,” underestimated by the traditional Haitian elite at every turn, appears to have skillfully appropriated the noiriste and populist mantle of Estimé, and could count on at least some genuine support in the countryside. And he could play the nationalism card to perfection, presenting Haiti as the injured victim of US racism and imperialism while extorting large amounts of aid by playing on US fear of communism. (He would occasionally invite the Polish or Czechoslovak legations for a chat, or let communist student unions stage the odd protest, just to show the Americans the dangers of not agreeing to his demands; the man had a singular talent for blackmail). But the “election” actually endangered the flow of aid (which, it should go without saying, was in large measure used for pure patronage purposes or simply stolen). It seemed to be more like an impulsive f*** you than a rational attempt to retain power.

My best "rationalistic" guess for why Duvalier nevertheless staged this electoral parody is that given the totally uninstitutionalized Haitian political context he might have thought that waiting two more years to steal an election might provide his enemies with too many opportunities to overthrow him; better to flush them out by an unexpected, enraging move like this than to give them time to prepare. And it certainly changed the political opportunity structure, since it entailed the cancellation of the scheduled presidential election of 1963, and thus foreclosed the option to battle Duvalier on an electoral terrain, however uneven; perhaps by forcing the opposition to adopt the techniques of the underground, he was moving the fight to a place where he had greater advantages, though this was a high-risk gamble. 

And yet all actors involved were forced to speak, with a straight face, the language of legitimacy, laws, rights, and popular sovereignty. Here, for example, is a bit Diederich and Burt quote from the Attorney General’s ruling, a masterpiece of this nonsensical rhetoric:
It is essential that immediately, even before counting the votes obtained by the candidates, we insist upon the principle which, far from being new, constitutes the very essence of national sovereignty. This principle can be defined: the members of the electorate, when presented with an electoral decree or law which looks to them incomplete, have the right to fully manifest their will to complete the law or decree and to designate a civil servant or a group of civil servants whose election was not foreseen. The intangibility of the principle once established, it will be easy for us to understand the the electorate of Port-au-Prince Arrondisement (used to establish legal precedent) has acted within its full sovereign power by designating François Duvalier for a new term under the title of President of the Republic. (Diederich and Burt, Papa Doc: Haiti and its Dictator, p. 169)
The language of legitimacy coordinates expectations even as it is being obviously flouted. Hypocrisy may be the tribute that vice pays to virtue, but this is not even hypocrisy; it’s more like trolling.

The Saudi Monarchy as a Family Firm

(I normally don’t write on current events, since I’m not a specialist in the politics of any country, but I had just finished Michael Herb’s excellent 1999 book All in the Family: Absolutism, Revolution, And Democracy in the Middle Eastern Monarchies when I heard the news that the Saudi King had died. Since I think Herb's thesis about the resilience of Arab monarchies in a world that is basically hostile to non-democratic norms makes a great deal of sense, I thought I’d add my 2 cents.)

Observers of politics have historically applied the term “monarchy” to a variety of superficially similar but sociologically quite distinct regimes: the Roman empire, the Carolingian kingdoms, the Romanov autocracy, the Kuwaiti emirate, the British monarchy. To the extent that there are interesting similarities accross these disparate cases, they have to do with the existence of recognized norms for selecting effective rulers only from a specific lineage (what the Polity coders call an “ascriptive” selection process, or more informally, selection by birthright). Ascriptive selection processes are typically connected both with certain understandings of the basis of authority (e.g., the king should rule because he is the Custodian of Mecca and Medina, not because he represents the people) and an exalted status for the effective ruler; the titles “King” or “Queen” and their various equivalents – Prince, Sultan, Emir, Emperor, Caesar, Shah, etc. – are first and foremost markers of status, elevating the person of the monarch above the common run of people and entitling them to visible honours not available to anyone else in society. The combination of an ascriptive norm of selection to offices with effective political power (rather than purely ceremonial positions) and a particular set of person-centered rituals and symbols defines monarchy, though it does not explain how monarchies survive.

Indeed, given the magnitude of the shift towards democratic norms of justification over the last two centuries, the survival of monarchies presents a bit of a puzzle. Though ascriptively-selected rulers were extremely common before the 19th century, nowadays the number of national states with effective monarchies is tiny; the Polity dataset identifies only 11 countries (Bahrain, Bhutan, Jordan, Kuwait, Morocco, Oman, North Korea, Qatar, Saudi Arabia, Swaziland, and the United Arab Emirates) where there is a norm of selecting members of a particular family for the top executive offices, and you might notice that one of them is not normally thought to be a monarchy but a totalitarian regime. (The data excludes countries with less than 500,000 population; including microstates might add Tonga, Brunei, Monaco, and Lesotho to the list, among others.) In six of these (Bhutan, Jordan, Kuwait, Morocco, Swaziland, and the United Arab Emirates) powerful monarchs nevertheless share some power with other institutions, such as elected parliaments (in the Polity jargon, these regimes have “dual” executives, combining ascriptive and non-ascriptive selection processes). Moreover, once discredited, ascriptive selection processes have proven difficult to resurrect explicitly, even if we broaden our view to consider cases where ostensibly “republican” leaders have tried to ensure that control over the state passes to their sons or other family members after their death or retirement, as Mubarak tried to do in Egypt and Gaddafi tried to do in Libya. There are few “transitions to monarchy” in the 20th century, and the few I can find were quite short-lived. Though many highly personalistic regimes have shown a tendency to turn into family enterprises, they seem to have had mixed success beyond the second generation when recognized selection norms remain “republican” (consider, e.g., the failure of the Duvalier or Trujillo “dynasties” in Haiti and the Dominican republic); North Korea is exceptional in combining ostensibly republican justifications of rule with a successful ascriptive transfer of power to the third generation. We could look at these stylized facts and conclude that the remaining monarchies are mere traditional survivals, doomed to extinction once they run out of oil rents or superpower patronage (a view associated with Huntington, I believe). Or we could conclude instead that the remaining monarchies are precisely the most resilient examples of a once common political form; whatever the Saudi monarchy is doing, for example, it has served it well for over 70 years.

Herb argues that monarchies that have survived to the end of the 20th century (the book was published in 1999) are in fact distinctive in ways that make them very resilient. In particular, most of these are what he calls “dynastic” monarchies rather than “personal” monarchies. (Some people suggest that surviving monarchies in Jordan and Morocco do not fit neatly in either side of this dichotomy, but we’ll ignore these subtleties for the moment since the Saudi monarchy, at least, is the paradigmatic example of a dynastic monarchy). A dynastic monarchy can be compared to a family firm, with the family business being the corporate control of the state (and the enjoyment of its oil rents, in the Saudi case), the king as the family CEO, the senior male relatives as the key executives and company board, and most of the remaining family members as shareholders and lower-level employees. By contrast, in other monarchies the royal family does not play much role in governance or even in sharing the spoils of power; the king rules either in alliance with independent power holders (Barons in medieval Europe, powerful politicians in modern times) or as personal dictators who have managed to keep all potential challengers directly dependent on him through their individual political skills.

The Saudi monarchy fits the dynastic model quite well. Senior members of the family monopolize all important state positions, such as the defenceinterior, and foreign ministries, and they play a role in determining the king’s successor. (Since 2007 there is even a formal institution, the “Allegiance Council,” staffed entirely by senior princes, that is supposed to select and confirm a new king and crown prince). Like a responsible company board, the senior princes have on occasion deposed rulers deemed to be irresponsible, and bypassed unsuitable candidates for the succession. For example, they briefly eased King Saud bin Abdulaziz from governance after he blundered with an ill-conceived plot to kill the immensely popular President Gamal Abdel Nasser of Egypt in 1958, and then more permanently in 1964, when they formally deposed him in favor of King Faysal; and the family chose not to make Muhammad bin Abdulaziz king in 1964 1975, despite the fact that he was the most senior of the surviving sons of Ibn Saud, probably due to general agreement within the family that his temper and drinking habits made him a bad candidate, according to Herb.

Moreover, because the family is so large – Yamani quotes an estimate of 22,000 royals in 2009; polygamy plus time produces lots of male-line descendants (Ibn Saud had 43 sons by many wives, who in turn produced many sons of their own) – it can control not only the “ministries of sovereingty,” but place its members throughout the state apparatus, and in particular the armed forces, where they serve to deter coups. In fact, the extended royal family serves as a parallel information-gathering mechanism through the practice of “audiences” with royals, which it uses to both understand what the population is thinking in the absence of a free media and to provide particularized patronage; as Herb puts it,
The ruling families, and especially the Al Saud, use the size of the family to extend the majlis [audience] system to as many citizens as possible … Like American members of Congress the princes of the Al Saud act as intermediaries between citizens and the bureaucracy, earning personal credit for solving the problems that arise out of a bureaucracy that is, in the first instance, a creation of the Al Saud (p. 43).
The family, like many a successful political party (or mafia), has a very hierarchical culture (deference to older members is strictly enforced), effective private dispute-resolution mechanisms (including special jails for misbehaving princes, apparently), and fora where princes are expected to speak candidly and honestly about what they learn from their contacts with non-royals (princes who develop reputations as liars are not likely to go very far). And in return for lifetime submission and service, all royals receive an allowance and a state job, calibrated to their seniority and political importance, from the enormous oil revenues the Saudi state produces. (Firm figures are hard to find, for obvious reasons, but Herb cites estimates that suggest that at the height of the oil boom, in the 1970s, the al Sauds received at least 12% of all government revenue - an utterly fantastic sum).

One of the key things that makes family governance work in this context is, paradoxically, the indefiniteness of the succession rule. The succession norm in Saudi Arabia, for instance, only establishes that the kingship should pass to the most senior “able” male descendant of Ibn Saud, rather than simply to the eldest son or brother of the current king. One might think that this would exacerbate the GoT-style succession conflicts common in many monarchies. (According to Kotkin, almost half of all Romanovs in Russia from Peter the Great to Nicholas II died in family disputes over succession issues, and Herb notes that the Ottoman Sultans even formalized their right to kill their surviving brothers on acceding to power in a “Law of Fratricide” in the 16th century). But Herb argues that the very indefiniteness of the succession norm, combined with the emergence of the modern state with its many positions to fill, actually incentivizes family members to “bandwagon” against ambitious princes who threaten the corporate hold of the family. Though individual princes may prefer to rule unconstrained by the “company board” of their senior brothers and uncles, they will typically prefer that the state remain in family hands over one of their brothers ruling alone or with the support of outsiders. And those who are not contending for the rulership have little incentive to jeopardize their position by supporting candidates who take “extreme” measures in their quest for power, such as threatening intrafamily violence or directly appealing to outsiders by developing alternative patronage networks or offering genuinely liberal reforms. For example, when King Saud bin Abdulaziz did a tour of the realm in 1963 distributing money to tribal chiefs in an attempt to salvage his position and undermine his brother Faysal by securing the support of “outsiders,” uncommitted family members quickly switched to Faysal’s side; as Herb says, the only effect the trip had was “to enrich some bedouin shaykhs and to further alienate his brothers, who sought a decree from the ulema declaring Faysal the ruler and making Saud king in name only” (p. 97). (Shortly after, Saud threatened violence against Faysal, which sealed his fate; he was now deposed for good). Given that different contenders will normally tend to offer similar “bargains” to influential family members and that other family members do not need to pre-commit themselves to one side or another, there is little point for uncommitted princes to strongly support candidates that threaten to overturn the family monopoly on power, while the “losing” contenders can expect to be rewarded with money and influence even if they do not inherit the kingdom. By contrast, a rigid succession rule provides incentives for ambitious royals to use more extreme measures (e.g., poisoning your brothers, appealing to the people) that risk the family monopoly on power.

On this account, the Saudi family does not remain in power because of special family bonds, the certainty provided by a clear succession rule, or some Saudi cultural predisposition towards monarchy, much less because of some special symbolic capital of kingship among Arabs. And though oil helps, Herb rightly notes that the price of support is subject to inflationary pressures; more oil revenues mean potential contenders must pay more for support. King Idris of Libya was overthrown when oil revenues were flooding state coffers (take a look at the GDP per capita line in this picture), partly because he had no family members who had incentives to defend him. The effects of US support on the al Saud family are also quite ambiguous: on the one hand, they mean the family has access to intelligence and resources otherwise unavailable; on the other hand, they provoke a cultural backlash that challengers can and have mobilized. Instead, the family's endurance in power is due to the fact that there are few incentives for family members to mobilize outsider support in their disputes; attempting to do so merely makes family members bandwagon against you. Hence, despite many divisions, on crucial questions the family tends to remain united; and a ruling class that is unified on crucial questions – meaning, a ruling class that does not seek to bring in outsider support to settle its major disputes – is very, very, hard to overthrow. 

This is not to say that the Al Saud family does not reach out to other sectors of Saudi society, distributing resources to favored groups or mobilizing symbolic capital to secure the support of the ulema, for example; but these actions would be quite ineffective if incentives pushed ambitious princes to mobilize outsider support on their own, “escalating” fights by, for example, courting the army or the clerical establishment as individuals. Moreover, even the mobilizing power of the symbols of kingship is typically quite limited. Herb tells a funny story that apparently circulated in the Saudi court in the 30s about the loyalty of the Bedouin to their emir:
As soon as it became clear that the Emir was going to be defeated, his Bedouin followers would be the first to turn and loot his army, justifying this by saying they were his friends and that as he was going to be looted in any case, they had more right than his enemies to the spoils (p. 62).
The Bedouin in the story did not dispute the legitimacy of the emir; they simply reinterpreted it to suit their interests when circumstances changed. In other words, as I’ve argued here in much more detail, the recognition of a norm of authority is compatible with all kinds of behaviours, including turning around once it becomes clear there are stronger challengers; to speak of the “legitimacy” of the Saudi king has very little explanatory power when we seek to explain why the Saudi system has endured. Indeed, in some respects the Saudi system has more in common with systems of single party rule than with medieval European kingship. The Al Saud are an odd party, to be sure; only women can join voluntarily (by marrying into the family) but without gaining any formal power (though they may have influence through their sons). But, with its internal dispute resolution mechanisms, its intelligence networks, its “service” requirements, the family basically mimics the institutions of an effective (if small) party on the Leninist model. And thus the incentives that keep it in power are not dissimilar from the incentives that kept the PRI in Mexico or the Chinese Communist Party in power: they are basically reasons for insiders to stick together and not seek outsider support, and thus to prefer corporate control of the state to going alone.

[Edit 2/3/2015. I got a date wrong - Muhammad bin Abdulaziz was passed over for succession in 1975, when he should have been next in line after Faysal's death. Now fixed.]

Political Instability at a Glance

(A graph-heavy post on the post-WWII history of political instability.)

(Update 1/24/2014: Thanks to Profs. Gleditsch, Goemans, and Chiozza for allowing me to use the beta version of Archigos, updated with leader information to the end of 2014)

Despite its ubiquity in everyday discourse, I find the concept of "political instability" exasperatingly vague, encompassing everything from polarized electorates to coups to civil war. Nevertheless, one can still understand most of the phenomena that fall under that rubric as the sorts of events that happen when the norms supposedly regulating political competition fail to be "recognized" as relevant or worth following by sufficiently powerful groups of people. Very wide-ranging normative breakdowns are revolutions and civil wars (Jack Goldstone once noted that the great revolutions were characterized by "fractal" breakdowns of norms regulating conduct at all levels); but coups, other forms of "irregular" leader exit, spikes of protest, and transitional situations can be understood as moments where the norms that are supposed to channel and limit the competition for power break down, either because sufficiently powerful groups disagree about what the relevant norms are, or because they want to change them, or because they can disregard them with impunity.

The identification of political instability events is unavoidably fraught, since what counts as the relevant norm governing political competition, and whether the norm has actually been violated, disregarded, or otherwise violently reinterpreted, will often be disputed. Sometimes it will simply be impossible to tell whether some particular event -- e.g, the recent happenings in Lesotho or the Gambia -- counts as a coup, or whether the fall of some leader is in accordance with "recognized" norms of political competition; indeed, I take it that sometimes there is simply no fact of the matter, though perhaps the very existence of disagreement about the nature of the event is itself significant as an indicator of instability. And of course many events that signal the weakness of norms regulating political competition -- aborted coup attempts, thwarted palace conspiracies -- simply never see the light of day. Nevertheless, it is still possible to get a glimpse of the broad patterns of political instability during the post WWII era.

Here's one way of doing it, which produces lovely "spectral lines" of macropolitical instability. The picture below graphs five forms of instability, per country: the estimated level of democracy and thus regime change, for the period 1946-2012 (from the Unified Democracy Scores by Pemstein, Meserve, and Melton); successful and unsuccessful overt coup attempts for the period 1950-2014 (vertical red and blue lines, respectively, from the data gathered by Powell and Thyne, supplemented before 1950 with data for successful and attempted coups from Marshall and Marshall); irregular leader exits (dotted black lines, sometimes coinciding, sometimes not, with the coup data from Powell and Thyne, and including everything from assassinations to revolutionary overthrow that occurs outside whatever prima facie normative framework of political competition holds in the particular country), from the period 1946-2014 (from the beta version of the Archigosdataset by Goemans, Gleditsch, and Chiozza - thanks for prof. Gleditsch for sharing a copy!); shaded colored areas track armed conflict episodes from 1946 to 2013 (from the UCDP/PRIO dataset); and periods of "interruption," "interregnum," or "transition" (light grey shaded areas; basically, foreign occupation, anarchy, political breakdown or explicitly transitional governments) from the polity dataset, in the 1946 to 2013 period. The figure is arranged regionally, by continent: African countries first, then American countries, then Asian, and so on, so that countries in geographical proximity to one another appear close together in the picture:
Coups, wars, irregular leadership transitions, changes in democracy, and periods of "interruption" are distinct phenomena, but they all indicate historical moments where the norms regulating "macropolitical" competition are fluid: where powerful parties don't agree about the definition of the state, the procedures for transferring power, etc. The graph is deliberately crowded -- it is meant to produce an overall glimpse of the "spectrum" of instability in the postwar history of each country, not a detailed history of each country -- yet some events are easily identifiable: major interstate wars (in green: the Korean War, the Vietnam war, the Ethiopia-Eritrea conflict, the Yugoslav wars); colonial liberation struggles (in red, such as the struggle for independence in Zimbabwe); the interminable series of conflicts of the Burmese state against its outlying "Zomian" minorities; the endless series of coups and countercoups in Argentina starting with Peron's first presidency in 1946; the coup against Allende in Chile in 1973; the disintegration of the Afghan state since the 80s; the transition to democracy in Spain; and so on. Each country has its own distinctive pattern of macropolitical instability, though in general wherever a country has experienced these sorts of events they have tended to "cluster" in time; macropolitical instability is rarely continuous over long stretches. Similar events also have a tendency to happen in similarly-situated countries, leading to distinct regional patterns:
At this level of aggregation we can see that South American countries have suffered more from coups than from armed conflict, yet coups and irregular leader exits have declined in frequency over the last three decades; that South and South-East Asian states (Myanmar, India, Vietnam, Laos, etc.) have suffered much more from armed conflict of all kinds than from coups; how states in Western Africa and Eastern Asia (basically, the Middle East) have seen a simultaneous decline in coups and an increase in armed conflict of all kinds. (Distinct events with regional implications are also visible - e.g., the central American wars of the 1980s). It is worth noting that these patterns coexist with an increase in measured levels of democracy in most regions of the world since the middle of the 1980s. (The horizontal red line in each picture represents a score of zero in the UDS data, which can be interpreted as the dividing line between democracy and autocracy; by that criterion, in a majority of regions of the world a majority of countries are democratic today, though in some cases barely so).

I suspect that some of these patterns are basically attributable to the timing of consolidation of post-colonial states. For example, if we could extend these pictures back in time we would see many more internal and even some external conflicts in Latin America, as states were consolidated after independence from Spain; much of the internal conflict we see in places like India or Myanmar against groups on their borderlands can be understood as state-consolidation conflict - conflict over who is subject to state power, and to what degree. But as states consolidate, struggles over the definition of the state may give way to struggles over the norms of political competition (coups and irregular leader exits); and these in turn can eventually either lead either to "stability" (relative consensus on the norms of political competition, or at least the victory of one faction or person over the rest, as in long-term personal dictatorships, leading to a decline in in coups and other forms of irregular leader exit) or state disintegration (renewed internal conflict). Consider a picture at an even higher level of aggregation, by continent:
One interpretation of this figure might go like this: the anticolonial struggles of African countries give way by the 70s to a fluid period of coups and countercoups as various powerful groups struggled to define the norms of political competition for control of the new states, often with the intervention of major powers during the Cold War. Yet instead of leading to the eventual victory of some particular norm of political competition, coups and countercoups eventually escalated into renewed conflicts over the very definition of the state -- "internal" wars of various kinds -- since the post-colonial state was a pretty recent and fragile creation to begin with. By contrast, in the Americas, the tendency has been for norms of "democratic" political competition to become entrenched in the context of relatively consolidated states; while the military may still intervene in politics, they find it harder to do so in an overt way. Though there are many reasons for this (including, e.g., changes in the foreign policy of the US) one important factor seems to have been the lessening of radical ideological conflict, which means deviations from norms of democratic competition are more costly and have less point. In fact, the risk of military intervention in politics in Latin America appears to remain highest precisely where ideological conflict over the nature of the state is fiercest, as in Venezuela and Ecuador. The Asian pattern in turn is less about the consolidation of new states than about border adjustment after the colonial period and the bringing of borderlands under central state control, rather than about the consolidation of new states; while the European post-war pattern mostly involves the late transitions to democracy of Southern Europe and separatist conflicts of varying intensity - all legacies of the wars of the first half of the 20th century, which of course are not visualized here.

For completeness, here are the political instability spectral lines of the world:
This is not especially informative (though it does show the trend away from interstate to intrastate conflict, and the long-run transition to norms of democratic political competition around the world), but I find it strangely beautiful.

Instead of aggregating these pictures of political instability, we can disaggregate them and expand them into "geological" pictures of the historical strata of political change. Here's one way of using the enormous amount of information available in these datasets to auto-generate political histories, using the example of Argentina. For the picture immediately below, start at the top, at the end of 2014; as we scroll down (the image is in its natural element online, with its endless scrolling; but one can imagine also a slowly unrolling codex) we move deeper into the country's history. The first thing we encounter is the name of the serving president as of the end of 2014, Cristina Fernandez de Kirchner; the name is grayed out - "still in office as of 2014;" leaders who died in office, retired without serving their full term, or were removed by irregular means (e.g., by a coup) are in darker font, to make them stand out (the darker, the more irregular). Each leader's name is placed at the date of his or her exit from power (or 2014 if still in office by the time the Archigos dataset ends), so anything below Kirchner until the next name appears happened during the Kirchner government. If data are available, we see a thick black vertical line representing the Polity score for that year; the further to the right, the more "democratic" its forms of political competition. A "thicker" measure of democracy, represented by the squiggly grey line with the ribbon, is also depicted -- the Unified Democracy score, which aggregates information from various attempts to measure democracy in a consistent way -- and scaled to fit in the same interval. Polity and the UD scores agree on the basic pattern, though the UD scores do not see Argentina's democratic institutions as fully consolidated by the end of 2012 (the last year of the UDS dataset); Argentina does not achieve the highest scores (which would put it bumping against the right side of the graph), and appears to be trending slightly leftwards as of 2012 (less democratic in this graph; no political implication intended). The blue line with dollar numbers represents Argentina's annual per capita GDP, as estimated by Angus Maddison and his successors: Argentina is a solidly middle-income country by 2010.

As we move down further, we encounter the end of the last military government, shortly after the end of the Falklands war, in 1984; the caretaker Bignone presides over the extrication of the military from government after Galtieri, who was mainly responsible for the war, is forced to leave office by his military colleagues. The period before that is one of coups and overall economic stagnation; more generally the pattern of Argentine history over the previous couple of decades is one of continual conflict in the context of boom and bust economic cycles, as we can see by the number of coups, irregular leader exits, and the conflict with the ERP. This is the time of the "dirty war," though it's worth stressing that it was also a period in which divisions within the military were exacerbated by the conditions of Argentine politics; most coups in the period replaced military leaders, not democratically elected leaders. As we move down (back in time), we see the traces of the "impossible game" between Peronistas and the military Guillermo O'Donnell described in his classic analysis of bureaucratic authoritarianism. Periods of repression alternate with classic populism in which the Peronistas are allowed to compete for power, each side of the conflict attempting to consolidate its advantages by transferring resources to its supporters in ways that always proved to be unsustainable given Argentina's dependence on the vagaries of foreign trade (represented by the generally flat trend in GDP, with many ups and downs); but no one ever fully succeeded in fully consolidating power before the terms of trade turned, inflation went haywire, and social conflict instigated either military withdrawal or military intervention. As we move deeper in time, we find that the period of instability really began in the 1930s, with the overthrow of Irigoyen, when Argentina is already a relatively rich country. Before the 1930s we find stability at a lower level of democracy: Irigoyen was preceded by a long sequence of leaders who left office in a regular manner without being overthrown by the military. We might thus speak of a "great cycle" of macropolitical instability from the 30s to the mid 80s, which probably had something to do with the way in which Argentina became integrated into the world economy (according to my meager reading, at least), though the decisions of successive governments as they attempted to consolidate their bases of support -- repression, coups, particular monetary and fiscal policies -- seem to have exacerbated the conflicts of the period.
Because I have a bad memory for people and dates, I like these pictures as aide-memoires, though of course they will only make full sense if one knows a little about the political history of the countries depicted. It's also worth stressing that the datasets involved have gaps and other problems. Though the universe of successful coups since 1945 is pretty well covered, for example, some "unsuccessful" coups never get reported, some coup-like events are not included due to ambiguity, and of course we do not see here spikes of nonviolent protest aimed at changing the norms of political competition (one could use the NAVCO data for this, but I had to stop somewhere, and the graphs are overcrowded enough already). The GDP data is sometimes dubious or interpolated, especially for some of the poorest countries, and of course it does not show the full the range of issues affecting living standards.
And Archigos stops at 2004 (though it's being updated), providing sometimes a false picture of stability for some countries over the last decade. [Updated: now using data to the end of 2014]

Nevertheless, more auto-generated political histories for 173 countries in the Polity dataset are available in the GitHub repository for this post. One can take a look at some really eventful histories, like those of Haiti and the Dominican Republic, which are full of irregular leader exits; or at Venezuela, which shows both the period of democratic consolidation following the overthrow of Perez Jimenez, marked by several coup attempts, and the long economic decline preceding the rise of Chavez; or indeed, any number of others. In general, one pattern emerges from these more detailed pictures, namely that there are two basic forms of stability: the kind that comes about when a single person achieves full personal power and successfully "coup-proofs" his rule (e.g., Trujillo in the Dominican Republic, Duvalier in Haiti, Gomez in Venezuela) and the kind that comes about when some norm of political competition is expected to be enforceable even at the death of the ruler. The first kind of stability is clear when you see a spike of coups, conflicts, constitutional crises, or irregular leader exits that signal some sort of succession crisis - a sure sign of a previous personal regime. It seems really difficult to transform regimes based on loyalty to a person into regimes where impersonal norms of political competition have "bite"; the instability after the overthrow of Gaddafi is more the rule than the exception, regardless of whether the leader was overthrown or died peacefully in office.

Let's look at coups in more detail, because they are perhaps the most dramatic single event in the data - a single short spike in these spectral lines. The first thing to note is that they are associated with lower measured levels of democracy:
 
In other words, coups have historically occurred most often in already non-democratic regimes; a famous coup against a democratically elected leader like the ouster of Allende in Chile appears to be less common than the many forgotten coups against military regimes all over the world. (Iraqi Prime minister Abu Zuhair Tahir Yahya is reported to have said in 1968, "I came in on a tank, and only a tank will evict me," according to Luttwak's classic handbook on the coup d'etat; most coups in the postwar era seem to have been against people who came in on tanks). Few coups take place against the "consolidated" democratic regimes, which is simply another way of saying that norms of political competition in such countries are recognized as binding by all powerful parties. But we also see few coups against the most autocratic regimes, which are typically regimes where a party or an autocrat has fully coup-proofed their rule.

Coups are thus a symptom of normative fluidity, while both fully autocratic regimes and consolidated democracies are consolidated precisely because their norms of political competition are not fluid, as Finer saw in his classic study of the subject. This is why one of the best predictors of the risk of a coup is another recent coup; "the claim to rule by virtue of superior force invites challenge; indeed it is itself a tacit challenge, to any contender who thinks he is strong enough to chance his arm" which "succinctly explains one of the most usual consequences of a military coup, namely a succession of further coups by which new contenders aim to displace the first-comers. 'Quitate tu, para ponerme yo,' runs the appropriately Spanish proverb." (the quote is from Finer, The Man on Horseback, pp. 17-18; for the statistical evidence, see here).

Most coups nevertheless result in some immediate reduction in the level of democracy as new leaders attempt to consolidate their power (and thus engage in repression), but especially since the end of the cold war, many coups are on average followed a few years later by some degree of democratization (or re-democratization). The classic case was the "revolution of the carnations" in Portugal which overthrew the "Estado Novo", and which led to the modern democratic regime there. Though not every coup today is a liberalizing coup, in general there has been more pressure for countries to hold elections and less tolerance for overt military rule since the 1990s, as Marinov and Goemans argue in detail. Given the dependence on aid of many coup-prone countries, this has typically resulted in quicker democratization after a coup than before the end of the cold war, where dictatorships of various kinds could count more consistently on various forms of superpower patronage. The figure below shows the aggregate pattern quite strikingly:
It's also worth noting that over the post war period coups did not always lead to military rule; on the contrary, they often issued in power struggles that led to personal dictatorships or other forms of authoritarianism. Indeed, "pure" military rule has been quite rare and short-lived in the modern period (characterized by professional militaries rather than military aristocracies); as Finer noted, and later research seems to confirm, some of the very features that give militaries in certain societies the ability to seize power make them particularly unsuited to ruling these same societies without extensive civilian collaboration, and in any case direct military rule tends to exacerbate divisions in the organization.

Using data gathered by Geddes, Wright, and Frantz on regime types, focusing on whether the main institutions of the regime are the military, a single party, a monarchy, or some combination of the three, and on the degree of "personalism" in the regime, we can use it to look at which coups were followed by periods of rule by the military as an institution:
As we can see, the periods of pure military rule (in blue) and mixed military rule (in green; this includes regimes that used a civilian party or where power was also highly concentrated in the leader rather than in a Junta) are surprisingly few; most coups have led to non-military dictatorships, especially personal ones. (Small quibble: the Geddes, Wright and Frantz data shows the difficulties of the enterprise of classification, and the ambiguities of political reality. For example, they classify the Franco regime as a "personal" dictatorship for its entire period; but any student of the Franco regime can tell you that power fluctuated, with the Falange and the military much more powerful early in the regime, though there is clearly a sense that power was highly concentrated in Franco early on as well. I would have classified the Franco regime as a hybrid military-personalist regime).
Coups are more common in poor countries, as one might have expected:
 
But how, exactly, does poverty matter? After all, some surprisingly rich countries have experienced lots of coups, while some very poor countries have had little recorded instability of any kind. Consider this picture, which replicates the first graph of this post, except that the countries are arranged from poorest to richest, and the squiggly line in the middle represents GDP per capita:
Here we see many high-middle income countries that were plagued by coups in the past and sometimes still today (Argentina, Thailand, Syria, Qatar) while some extremely poor countries have never experienced coups (e.g., Malawi). Poverty seems to matter only where authority norms find few organized defenders, or rulers have failed to coup-proof their regimes; and this only because very poor societies seem to have been commonly places where the only organized force of national stature has been the army, and coup-proofing is tricky political work requiring resources that are not always available. (Finer's views are still quite reliable here, though he tends to speak too much of "legitimacy" when he really means organized support; it's not that poor people welcome coups or military rule, but that in poor societies the organized groups that have power are often incapable of resisting the army, and in twentieth century contexts powerful groups have had many different views over which authority norms should prevail).

Interestingly, though poverty is strongly associated with coups (and is typically found to be a significant risk factor in quantitative studies), economic growth is not so strongly associated; it is actually quite hard to find a significant effect of growth on coups in the quantitative literature, despite the fact that it's easy to tell stories about how economic decline might be a trigger of political instability. Though coups have clearly happened in periods of both growth and decline, one could nevertheless squint at the distribution of growth rates in years with coups and conclude that coups have tended to happen in years with slightly lower growth rates than average:
Indeed, it is not even clear that coups result in lowered growth rates in their aftermath (though as far as I can tell the statistical evidence suggests coups typically lead to some decline in growth rate). Consider this picture, showing normalized GDP (100 at the year of the coup) in the years before and after a coup or coup attempt (successful coups are in red, unsuccessful attempts are in blue):
In some cases, we see a U-shaped pattern - economic decline followed by coup, followed by recovery later; in others we see a line sloping down, and in others we see a line sloping up. Coups have happened when income was growing greatly (Libya), and when income has been declining greatly (Iraq, Chile); in periods of recurrent boom and bust cycles (Argentina) and in periods of apparent macroeconomic stability (Thailand, Greece). Sometimes they have been followed by quick recoveries, others by wild fluctuations; ten years after the Pinochet coup Chilean GDP was at the same level as in 1973, though it had oscillated wildly in the intervening period. The key point seems to be that coups are symptoms of underlying political conflict, which may be triggered by factors other than economic instability; even in the Argentine case, where coups where recurrently triggered during economic crises, the problem seems to have been the political conflicts (strikes, riots, etc.) that often came with the economic crisis and that made the military frame the situation in security terms. Thus the relationship between coups and economic growth will depend on the relationship between political conflicts and economic life.

Nevertheless, the macroeconomic aftermath of coups also seems to have varied from before and after the cold war, in line with the Marinov and Goemans thesis mentioned above:
Coups before the cold war on average seem to have happened in periods of growth, and were not necessarily followed by economic recession; coups afterwards seem to have happened on average during periods of severe economic contraction and to have led to further declines. Perhaps this shows that coups have been punished more severely in the post Cold war era, so that only severe economic crisis has led to coups after 1990; or that coups during the cold war happened more often in countries where economic performance is more or less independent of political stability (e.g., oil-dependent countries, like Iraq). But I found the lack of obvious connection between political instability and economic instability striking.

I think overall it is probably fair to say that some forms of macropolitical instability (coups, irregular leader exits, regime transitions involving major normative changes, like transitions from monarchy to democracy) seem to be on the wane. But there is little in this history suggesting that such instability ever definitively ends; on the contrary, though some countries have good long runs of stability, big shocks to the global system (big economic changes, big wars) can trigger periods of instability with very long after-effects. This is probably a bit depressing; it suggests that the events started by the Arab uprisings, for example, will take a long while to work themselves out (mostly in ways that involve "political instability"), until a new normative equilibrium is eventually reached.

Code for all the graphs in this post is available at this Github repository. The vast majority of the code is basically data-munging; you will need to download some of the datasets separately.

(Update, 1/24/2014: using Archigos data for 2014 now)
