Varieties of Political Competition

(Part 1.5 of a series on the history ofpolitical regimes. This gets a bit technical in the second half, which contains a sort of blurry sketch of a theory of political regimes)

Our political vocabulary has a very long history. Terms like democracy, dictatorship, autocracy, tyranny, and even words of more recent vintage like authoritarianism or totalitarianism carry a great deal of descriptive and evaluative baggage, acquired in the course of political debate over a long time. They are rich, many-layered concepts, useful for simultaneously referring to and evaluating complex and vaguely-defined combinations of institutional, cultural, and other aspects of social systems. But by the same token, all that baggage makes it very difficult to use these terms to track the history of political institutions in anything but the roughest fashion. Or at least the history of the forms of political competition for power in states.

Consider an apparently simple question like how long the USA has been democratic. Since independence in the late 18^th century? Since the 1820s? Since reconstruction? Since the introduction of women’s suffrage? Since the 1960s? Never? Since the 1960s but only until recently? Until the 1930s? Historically, the idea of democracy has provided support for all of these answers, and all of them have had advocates. And though the current usage of the word "democracy" makes some answers more plausible than others, the controversy is pretty much ineradicable. We may at best be able to agree that the USA today is likely to be more democratic in some ways than in the late 19^th century (a more inclusive suffrage, more tolerance of certain forms of dissent), but perhaps less democratic in other ways than in the 1930s (a more entrenched and pervasive national security bureaucracy that is impervious to political control, greater structural barriers to entry into political competition, etc.). Moreover, even if we agreed that the USA has been democratic for some particular period, this would not necessarily tell us much about how competition for control of the state changed during that time: how norms of leadership selection evolved, how barriers to entry into political competition changed, how the ability to constrain the actions of the winners of the competition for power waxed or waned, etc.

Now consider instead the question of how long the USA has selected its top political leadership via competitive elections where candidates must enlist the support of a substantial fraction of a relatively large group (much greater than Dunbar’s number) to gain power, and where entry into political competition is normatively regulated (there are relatively well-enforced rules about who can be a candidate for power) but where such regulation does not impose large formal barriers to entry (the rules imply the existence of large pool of potential candidates representing a wide variety of interests and with a wide variety of life experiences and skills, even if structural barriers like access to money or racism considerably reduce this pool in fact). This question is in principle answerable (a: since the early 20^th century, at least), but it is not identical to the question of whether the USA is or ever was a democracy, whether in the USA “the people” or “the rich” or “the well connected” rule or have ever ruled, or indeed the question of whether its political system is any good at all.

It seems plausible to say that this method of leadership selection (competitive election) must be a component of democracy in large states (i.e., that no state without some such method of leadership selection can be called a democracy), yet this implies a whole theory of democracy relating competitive elections to ideals of inclusion and autonomy that is itself contestable. Ancient Greeks, for example, thought elections were characteristic of “oligarchic” regimes (rule by the rich), for understandable reasons having to do with the typical barriers to entry into political competition they presuppose (when offices are open to election, only the rich are able to compete for them effectively, as the American primary season certainly suggests); in their view, sortition [selection by lottery], not election, was more appropriate to the ideals of citizen equality implicit in the notion of demokratia (the power of the demos) and isonomia (citizen equality before the law) as they understood it. (They were certainly right for their political context; and perhaps their ideas are worth taking seriously today as well). Even the idea that elections are an institution of accountability (and hence something that helps “the people” to rule) rather than a mechanism of selection (useful only as an efficient way to discover the most talented rulers for an already established hierarchy) is a relatively recent development. At any rate, even if we agreed that competitive leadership selection through vote-gathering in large electorates is part of any definition of democracy in modern states, this does not imply that we would agree on the relative importance for democracy of such elections relative to, say, the inclusiveness of the electorate, the existence of a culture of tolerance, the responsiveness of elected officials to public opinion, or the protection of various rights.

From the point of view of trying to write a history of political regimes, it may thus be best to proceed in a disaggregated way: to speak not of democracy but of regimes where leadership selection is conducted on the basis of competitive elections with large electorates and few formal barriers to entry, for example, as I tried to do in my previous post. Instead of saying “democracy” we say CE/LG/LBE regimes (competitive elections/large group support/low barriers to entry). We thus substitute collections of small and relatively unimportant ideas like political competition through elections for large but important ideas like democracy, and then check whether these individually small and unimportant institutions come together in particular ensembles that make a difference to the things we care about. (E.g., like whether some particular combination of large-group elections, low barriers to entry into political competition, etc. actually tends to evolve over time, and whether these combinations tend to make a difference to the realization of particular ideals of autonomy or freedom). This avoids the historical tangledness of existing regime concepts, though at the cost of bracketing, at least for a time, evaluations of actual institutions. But at least then the important questions become either empirical (which institutions lead to the realization of particular ideals?) or purely philosophical (how should we weigh the relative importance of political values like equality, participation, etc.?).

I am primarily interested here in the institutions that shape political competition for the control of states (so non-state spaces are out of consideration for the moment), as well as the institutions that constrain the winners of such competition: the “varieties of political competition” for short. What we want to know are the “parameters” that describe such competition. What distinctions are useful for thinking about these varieties? A sketch of a theory of political competition might look at the following questions, only some of which overlap with the traditional concerns of democratic theory:

1.  As in the previous post, we might want to know whether the selection of those who control the state is regulated by more or less “self-enforcing” norms or not; periods where people attain power primarily by force (coups, revolutions, etc) seem to be substantially different than periods where people attain power in a normatively regulated way. Whether norms are self-enforcing depends on the commitments and resources of the actors subject to them, not on the norms themselves, since no third parties outside the regime exist to enforce them by definition (in other words, constitutions are mere pieces of parchment unless everyone can credibly commit not to defect). It would then be useful to know whether we can say anything general about the conditions that make some selection norms (hereditary, competitive, etc.) self-enforcing, not just competitive electoral selection norms.
2. We might also want to know which form the norm of leadership selection takes: whether the norm is to select people who fit a certain definite description (as in monarchies, where the next ruler is the heir of the current ruler), or to select people whose names are produced by some random process (lottery), or who meet a certain explicit standard (“meritocracy”), or, more commonly, who can show sufficient evidence of support within a group of “selectors” (election, acclamation, negotiation within the Politburo, etc.). (Mixtures of all of these selection norms are possible, especially when the state contains more than one center of power; in which case we might want to know something about the relative “powers” of these centers of power). Which selection norm is in force seems to have some effect on how long a leader is in power; selection norms that require a leader to show “evidence of support” appear to make it harder for leaders to keep control of states than selection norms that do not. It might also have an impact on the quality of political leaders (ungated), or on their social background. 
3. We might wish to know the size of the group whose support must be mustered when selection is regulated by “evidence of support” or "random" norms, as well as the kinds of barriers to entry into this group. This is in part because when contenders for power must show support from large groups (say, 4-5 times Dunbar’s number, or around 600 people, the size of the typical Central Committee of a communist party), elective institutions almost invariably develop; usually the only way to show that you have the support of 100,000 people is to count them. Moreover, small selector groups almost always indicate highly hierarchical social structures, require different sorts of “payment” by contenders hoping to secure support, and are easier to “cartelize” (preventing contenders from expanding the boundaries of the group by escalating political competition outwards).
4. We might wish to know the sort of “industrial organization” prevalent in the political arena (by analogy with this). For example, in many countries where control of the state is allocated to those who can show support from large numbers of adult citizens via elections, the political arena is typically organized around a few large multipurpose “firms” (parties) who are the main competitors for control, along with a large number of small special purpose groups (think-tanks, civil society groups, PACs, etc). Though the formal barriers to entry into this arena are low, the structural barriers are large (creating a party capable of appealing to large numbers of people takes real economic and symbolic resources), so that political competition operates in practice in an “oligopolic” manner. In other countries, political competition is fully monopolized by a single multipurpose “firm;” in yet others there is a dominant political firm but many special-purpose groups that cannot directly compete for power. Moreover, competition between the main “firms” in the political arena can be more or less regulated by norms that limit the permissible methods of competition. I know there is a well-developed theory of party systems for democracies, but it is not integrated with a theory of politico-industrial organization in other political systems; and we might want to put all of this in a single framework if we are interested in the history of the varieties of political competition.

Simplifying a bit, you might end up with a typology of varieties of political competition like this:

The table could be extended further; but it might get a bit too technical, and I’m not sure how illuminating it would be (more in part 2 with actual graphs and less theory, assuming part 2 ever arrives). The interesting questions would then be about which forms of politico-industrial organization can stably coexist with particular selection norms, and which of them actually produce good consequences, if any; but it might take me a while to get there, if ever.

A Very Short Quantitative History of Democracy, Dictatorship, and Other Political Regimes, Part I

(Part I of probably two).

Readers will have to forgive me, but I find dataset blogging addictive. One can use historical datasets to tell stories, not just to test models, yet outside economic history one hardly finds much quantitative history, much less quantitative political history, out there. Nevertheless, the Polity IV dataset I described in the previous post, with its long-run coverage and wealth of information about patterns of political authority at a global level, lends itself to the sort of quantitative history of political regimes I have in mind.  Though this sort of history is not always advisable, it provides a powerful antidote to the most common failings of what passes now for the history of democracy and other political regimes: excessive Eurocentrism, and annoying tendencies towards either Whig triumphalism or Hegelian determinism. (An exception here is Adam Przeworski’s excellent book Democracy and the Limits of Self-Government, whose self-consciously global perspective and use of long-run quantitative data makes it one of the most eye-opening books I’ve read on democracy and its history). My hope is that a little bit of quantitative history can mitigate some of the nonsense people seem to believe about democracy; and since I’ll soon start teaching my “Dictatorships and Revolutions” course again (more on this in a different post), I thought I’d try to use the Polity data to graphically chart the evolution of different patterns of political authority over the last couple of centuries for the benefit of students and perhaps others.

A couple of methodological points before starting. First, though the Polity IV data is pretty substantial, going back to 1800 in some cases, it does not track every single polity within that period. The focus is on nation-states, and indeed nation-states that have survived up to the present; lots of states that did not survive to the present time (because they were annexed by other states or disappeared through other processes) are not included, though some historical polities are (Prussia, Bavaria, Wuerttemburg, the Kingdom of the Two Sicilies, Sardinia, the Papal States, Modena, Parma, Tuscany, a few others). Colonial dependencies of these independent states are not coded; the dataset codes only the regime at the imperial center (though we can correct for this bias to some extent, as we shall see). Moreover, some of the polities that are included in the dataset from 1800 onwards (Austria and Turkey, for example) have experienced so much change (from Austro-Hungarian empire to Austria, and from Ottoman empire to modern Turkey) that one doubts the wisdom of having a single time series for them (rather than, for example, a time-series for the Austro-Hungarian empire and another for Austria). And Polity does not collect information about “micronations” (less than 500,000 inhabitants), which means that its coverage of Oceania (Polynesia, Micronesia, and Melanesia) is spotty at best. Finally, it is also worth noting that in the long span of time covered by the dataset many areas of the world, some of them incorporating substantial populations, were effectively stateless: James C. Scott’s “Zomia” in Southeast Asia is one of these regions, but every continent has had (and sometimes continues to have) large non-state spaces. Statelessness does not mean that people live without political authority, but authority is far more fluid (and often has different implications) when exit is relatively easy, as it has historically been in stateless areas, than when exit is more difficult, as it has often been in state zones.

Second, as I was saying in the previous post, the dataset does not track every feature of political regimes that might be of interest. It purports to measure only three general concepts: the mechanisms of executive recruitment in states (how leaders come to hold power over a central state apparatus), the forms of political competition (how groups contend for control over a central state apparatus), and the degree of executive restraint (how much the power of the political leaders at the centre is limited: political discipline). Though all three measures are very highly correlated (above .99), I strongly suspect that while executive recruitment and political competition do measure fundamental if related aspects of the political regime, executive restraint is best understood as a function of the other two, plus temporary changes in the configuration of political forces that are not part of the political regime properly speaking. In other words, to the extent that “executive restraint” is not simply picking up paper constraints (whether the constitution says this or that about a political leader), it must be picking up the ways in which the groups that play a role in political competition and selection are able to sanction the main government leaders in the state. So in what follows I will mostly ignore the measure of executive restraint and focus on executive recruitment (this post) and political competition (in part II).

Let’s start with the mechanisms of executive recruitment. In the Polity classificatory scheme, leaders can come to power in two basic ways: through unregulated political activity (your classic coup d’etat, for example) or through some norm-regulated process (like hereditary succession, competitive election, etc.). Norm-regulated processes can in turn be divided into those where political leadership is allocated, at least in principle, on the basis of “ascriptive” characteristics (like what family you were born into), and those where political leadership is allocated by explicit selection within a particular group. (No modern polity allocates political leadership by lottery, unlike many ancient ones; this may be a modern mistake). Finally, selection can occur through relatively open competition within a relatively large group (election, though not necessarily universal suffrage election), or through informal processes within small groups ("designation;" e.g., like the process of selecting the First Secretary of the Communist Party of the Soviet Union). These three dimensions of political competition lead to a seven-fold set of categories: pure ascriptive (absolute hereditary monarchies without powerful prime ministers); ascriptive plus small-elite selection (absolute monarchies with powerful prime ministers, for example); ascriptive plus large-elite selection (powerful monarchs confronting powerful elected prime ministers, for example); pure small-elite selection (single party regimes, for example); pure large-group selection (competitive electoral regimes); small group plus large-group selection (what polity calls “transitional” or “restricted” election regimes, though they are often not very transitional at all but merely regimes where small elites cannot select the leadership without some form of large-scale electoral competition, even if unfair); and self-selection regimes (unregulated selection). Polity also has a confusing “executive-guided transition” category that I don’t much like, but basically indicates a period of transition from a self-selection regime to a norm-regulated selection regime. (In fact, for most purposes it can be replaced by the self-selection category, since it does not actually indicate a change in executive selection mechanisms and relies on uncertain analyses of leadership intentions). So what do we see when we look at the evolution of political authority through this lens?

Fig. 1

Vertical lines and shaded areas indicate, from left to right, the First World War, the beginning of the great depression, the Second World War, the beginning of African decolonization, and the end of the Cold War and the breakup of the Soviet empire. Black/grey areas at the bottom of the graph indicate the number of countries falling into Polity’s three “transitional” categories: regime transition, anarchy, and foreign occupation. You must also imagine much of the white space in the graph – representing lots of colonial possessions – to be colored dark red and green, since rule over colonial possessions was exercised through limited elite and ascriptive selection regimes, even if regimes at the imperial center were different.

A few things are worth noting. First, there is a slow but steady trend towards more large-group selection regimes – relatively competitive elections of all types, even if mixed with small-elite selection (as in competitive autocracies). These elections are not always fair [update: and suffrage is not always universal or even close to universal], but by my count nearly 70% of all regimes in 2010 involved some form of meaningful competition for executive power within large electorates, while only 30% or so did in 1900:

Fig. 2

Large-group competitive selection is now the norm, not the exception, a change that happened over the course of a century but begins in the 19^th century. But though the overall trend is clear, the proportion of large-group competitive selection regimes fluctuates quite a bit, apparently in response to major political events: the two world wars (one can identify them just by looking at the spikes in regime collapses), the beginning of decolonization, the end of the Cold War and the collapse of the Soviet Union. Interestingly, the great depression barely rates a blip – it hardly affects the trends in executive recruitment patterns. And the current trend towards more large-group selection regimes starts in the mid 1970s (the oil shocks? The exhaustion of the appeal of single-party regimes?), though it appears to accelerate by 1989. Oddly, the 70s are also the great age of coups (“self-selection” regimes – lots of these emerged with decolonization) as well as the apogee of limited-elite selection regimes (single-party regimes, especially). The data thus seem to point to a future where most regimes recruit their leaders through electoral competition (not necessarily fair!) appealing to large groups, but there is still a substantial minority of ascriptive recruitment regimes (monarchies, basically) and limited-elite selection regimes; it’s as if the only long-term stable equilibria are either competitive elections or full-blown monarchies.

Moreover, the phenomenon is pretty much global: competitive regimes with elections that appeal to large electorates are now found in every continent:

Fig. 3

(Includes both competitive electoral regimes and competitive autocracies [mixed large group/small group selection]; the picture is not substantially different with only full competitive electoral regimes included). But it was never just a European phenomenon: competitive regimes (even if not always very stable and electorally fair) are first of all an American phenomenon (and I don’t mean North American). Most large-group electoral selection regimes in the 19^th century were in the Americas (the USA, Canada, Peru, Colombia, Chile, Costa Rica, Honduras, Bolivia, Argentina, Guatemala), though we even find some in Africa (Liberia for a time, which of course was in part an American import). Genuine electoral competition for power with an appeal to large electorates is a New World invention, but not a specifically North American one, even if the North American version of the experiment proved relatively more stable than many of the South and Central American versions. To be sure, the fact that a regime is competitive insofar as executive recruitment requires an appeal to a large electorate does not mean that it is a democracy in the full sense of the term (however you want to define it); many of these competitive regimes included important restrictions on suffrage (slaves and women needed not apply), and elections were not always fair or fully free. But all of the regimes in figure 3 are fundamentally different in kind, at least with respect to the mechanism of executive selection, from regimes where leaders are selected either by ascription or by informal competition within a small elite.

Here’s a more fine-grained picture of the distribution of such regimes since 1950:

Fig. 4. Competitive regimes per region.

(As I mentioned earlier, coverage of Oceania is pretty sparse in the dataset, so you might as well ignore the Melanesia, Polynesia, and Micronesia cells). As we can see, these regimes are now common basically everywhere; the only laggards are Central and Western Asia, where large-group selection competitive regimes (let's not speak of democracies, however) are still less than 50% of the total.

Non-electoral regimes – monarchies, single-party regimes, etc. are now almost exclusively found in Asia and Africa, though they used to be pretty evenly distributed throughout the world:

Fig. 5

Interestingly, the only real shocks to the distribution of these regimes seem to have been decolonization in the 1960s and the end of the Cold War in 1989. It is as if new countries generally end up with limited selection or unregulated recruitment regimes, and it takes a while for them to move either toward large-group selection or full monarchy. 

We can also look at this history in combination with the history of economic development. Using data from the Penn World Tables (caveat: some countries have no income data, and what data exists only goes back to 1950 for most countries), we can see that the rise in competitive selection regimes is visible in every income quantile except the highest:

Fig. 6

The proportion of competitive regimes in the richest quantile seems to be declining over time (and stabilizing in the third quantile) at about 80% of all regimes, as stable oil monarchies and other limited-elite selection groups rise to the top of the income distribution. As Przeworski has argued, there seem to be diminishing returns to conflict over executive selection mechanisms in rich countries, so all regimes should be relatively stable at high levels of income per capita. To be sure, full electorally competitive regimes (with “free and fair” elections) are less common in poorer countries, but even if we restrict ourselves to these regimes, we get basically the same picture:

Fig. 7

We can actually investigate this further by looking at the “transition matrix” of regimes over this period of time per income quantile. We basically look at what the regime is like at time t, and then what it is like at time t+1, and make a matrix, where each cell represents the percentage (number) of cases over the period in question where a mechanism of political selection in the rows changed to one in the columns (so the diagonal represents stability):

(Click here for a full spreadsheet version). Here we see that mechanisms of executive recruitment in countries in the poorest quantile remained stable about 90% of the years in question (i.e., on average they switched to another selection mechanism about once every ten years); by contrast, at the richest quantile, only self-selection regimes were stable less than 95% of the time. Competitive electoral regimes in the richest quantile were stable basically 100% of the time; but all other regime categories were also stable, and hereditary monarchy was basically just as stable as democracy at this level of income (more than 99% of the time). Even state breakdown appears stable in the richest quantile; those puzzling 13 years of stable state breakdown in the second table represent Lebanon, which appears to have maintained a relatively large income per capita during the years of civil war (though note economic data is likely to have been spotty and unreliable during that time, so take that factoid with a large scoop of salt).

Moreover, rich countries were likely to transition to competitive regimes if they transitioned at all; and the regimes most likely to transition where the self-selection regimes, whereas in the poorest quantile we find transitions to a wider variety of other regimes.

So where does that leave us? More in part II (looking at the forms of political competition over this period), but basically I think what we see is the political manifestation of the long process of global economic change since 1800 (the industrial era). We start with ascriptive selection and limited elite selection regimes everywhere in the world (or at least in zones of state power), but economic change slowly alters the basis of political power in them (more so in certain kinds of economies than others). These changes render norms of political selection unstable, and more particularly they make it possible for elites (new and old) to “defect” from previous norms of selection by appealing to larger groups in the selection process (this, generally, means elections). And global political shocks (the world wars, the breakdown of empires) can push the process in particular directions at least for a time – e.g., towards single party regimes in the wake of WWII and decolonization, or towards electorally competitive regimes after 1989. But after countries reach a certain level of income, political competition over executive recruitment is less useful; so all regimes eventually stabilize. 

Code necessary for replicating the graphs in this post, plus further graphs and ideas for analysis, in my repository here. (Still pretty rough, though). You will need to download the Polity IV and Penn World Table datasets directly.

[Update 21/2/2010: added a few small clarificatory remarks about how comeptitive elctoral regimes are not necessarily democratic in the full sense of the term]

The Half-life of Leaders and the Half-life of Regimes

Thinking back on the last couple of posts, a couple of questions arise naturally. First, there is the question of the survival of regimes in general, not just democracy: if most democracies die within 15 years or so, what is the median duration (the “half-life,” if you will: the time it takes for half of them to be gone) of other regimes? And second, there is the question of the relationship between the half-life of regimes and the half-life of leaders: do regimes whose leaders tend to have longer half-lives also have longer half-lives? My interest in these questions stems from my current research on the question of legitimacy: my sense is that legitimacy matters much less than people usually think to the survival of large-scale patterns of political power and authority, so I’m interested in trying to figure out if there are systematic differences in survival between more and less “legitimate” regimes and other political structures. So this is another exploratory post, with lots of graphs.

How do we measure the duration of non-democratic regimes relative to democratic regimes? Though democratic regimes are not always straightforward to identify, non-democratic regimes come in a much wider variety of forms – from hereditary, absolute monarchies to single party regimes and multiparty hybrids, and some of these forms shade gradually into one another over the course of many years. (For a sense of this variety, consider the differences between Mexico before the 1990s under the PRI, whose presidents succeeded each other with clockwork regularity every six years and a lively opposition existed but could never win the presidency, North Korea today, where opposition is non-existent and succession is controlled by a tiny clique, and Mubarak’s Egypt.) To get a handle on this question, I’m going to use the Polity IV dataset, which codes “authority characteristics” in all independent countries (with population greater than 500,000 people) from 1800 to 2010. (I’ve been convinced by Jay Ulfelder’s work that the DD dataset I used in my earlier post is not appropriate to study comparative regime survival due to the way it codes certain democracies where alternation in power has not occurred as dictatorships, which systematically biases the survival estimates of democracies upwards).

The Polity dataset is fairly rich. Most researchers seem to use only the composite indexes of democracy and dictatorship it offers, but these indexes, while useful, do not have a strong theoretical motivation, as Cheibub, Gandhi, and Vreeland argue here. For my purposes, it is best to use the dataset to extract those authority characteristics of political regimes it purports to measure: the mechanisms of executive recruitment, the type of political competition, and the degree of executive constraint. Mechanisms of executive recruitment include hereditary selection, hybrid forms combining hereditary and electoral mechanisms, selection by small elites, rigged elections, irregular forms of seizing power, and competitive elections; types of political competition range from the repressed (all opposition banned, as in North Korea) to the open (typical of thriving democracies); and executive constraints range from unlimited to “parity” with the legislature. (See the Polity IV codebook for a full discussion). In theory, the dataset distinguishes eight kinds of executive recruitment mechanisms, ten types of political competition, and seven degrees of executive constraint, plus three different kinds of “interruption” (including breakdowns of state authority, loss of independence, and foreign invasion and occupation), leading to a possible 563 possible patterns of political authority, but these dimensions are all highly correlated (over .99); indeed, only 212 combinations of executive recruitment, political competition, and executive constraint actually appear in the date, most of them only once and for short periods of time, and it is obvious that some combinations do not even make sense. (And those that do make sense do not always capture all the information we would normally want about a political regime: Polity has no good measure for the extent of suffrage in competitive regimes, for example). But the dataset helpfully indicates how long each of these patterns last, so we can attempt a first cut at the question of the half life of regimes using a Kaplan-Meier graph:

The half-life of an “authority pattern” – a combination of an executive recruitment mechanism, a type of political competition, and a specific form of executive constraint – is 6.6 years, though the tail of the distribution is very long: some of them have lasted for upwards of a century. Switzerland, for example, has had the same authority pattern for 162 years, and Afghanistan retained the same authority pattern from 1800 to 1935 (a hereditary monarchy). As it happens, social and political life comes to be mostly structured in most places by the long-lasting patterns, but most patterns of authority do not last that long. Incidentally, at this level of abstraction there are no great regional differences in the half-lives of authority patterns, though it does seem as if authority patterns last slightly longer in Europe and the Americas than in Africa and Asia:

Yet an “authority pattern” is too amorphous a unit of analysis. We might get a better handle on the question of comparative regime survival by looking specifically at the mechanism of executive selection, since the manner in which the chief power in the state is selected is normally thought to be quite important and to have far-reaching consequences: whether supreme power is achievable by hereditary succession only or through designation within a closed elite or via competitive elections or some other means seems to have important consequences.

Of all the mechanisms of executive selection identified in the Polity IV dataset, only one, “Competitive Elections,” is unambiguously democratic by most people’s lights. Though within the dataset the fact that a regime has competitive elections is no guarantee that it will also have universal suffrage, for the most part “competitive elections” identifies most countries that most people think are democratic. We can thus calculate the duration of all periods of “competitive elections” and compare them to the duration of all “non-democratic” periods – those periods where executive selection happened through some other means. The details are somewhat tricky (see the code), but here are the results:

Some notes. As we might have expected from the discussion in the previous post, full hereditary monarchies (Russia under the Tsars, Saudi Arabia, Iran under the Shah, Portugal and Romania in the 19^th century, Nepal in the 19^th century, among others; there are 65 episodes in 40 countries in the dataset) have the longest half-lives (nearly 32 years; this increases if we collapse the two hereditary monarchy categories. Note these are not “constitutional” monarchies like the British one). But competitive electoral regimes are no slouches, with a half-life of about 17 years (in keeping with Jay’s numbers in this post, though he uses a different dataset), and as time goes on their survival rates seem to converge with those of monarchies. Similarly, “limited elite selection regimes” (e.g., single party-communist regimes, where a narrow clique selects the leader without open competition) have a half-life comparable to that of democracies, but as time goes on they tend to break down more; their survival rates seem to diverge from those of competitive electoral and monarchical regimes. Low survival rates are found especially among political forms that appear to have internal tensions, such as competitive authoritarian regimes, where elections exist and are contested by an opposition, but it is very hard for the opposition to attain real power (e.g., Zimbabwe today). I confess I don’t really understand Polity’s “Executive-guided transition” category, but it’s obviously a regime that is turning into something else (the Pinochet regime in Chile after the 1980 referendum but before the return of competitive elections counts, for example), and “ascription plus election” includes regimes where the monarch retains some real power but the legislature and other executive offices are no longer under its thumb  (only a few are recorded in the data, including Belgium in the late 19^th century and Nepal in the 1980s and 90s); it makes sense that such regimes, halfway between “real” monarchies and purely constitutional monarchies like the British, should have short half-lives as the conflict plays out and either turn into competitive electoral regimes or into more absolute monarchies.

It is also interesting to compare the relative survival rates of competitive electoral patterns of authority vis a vis periods where selection happens by non-competitive electoral means (regardless of whether the selection means stay the same):

Though the difference seems to narrow as time passes, the half-life of non-democracy since the 19^th century has been a bit longer than the half-life of competitive electoral regimes (23 vs. 17 years). In sum, political regimes do not last much more than a generation.

(For those still following, the regional breakdown indicates that competitive electoral periods have had the longest half-lives in Europe and the Americas, whereas non-democracy has had the longest half-lives in Africa and Asia; no special surprises there, though I am not sure about the reason).  

How does this relate to the half-life of leaders? For that, we turn to the ARCHIGOS dataset by Goemans, Gleditsch, and Chiozza, which contains information about the entry and exit date of almost all political leaders of independent countries in the period 1840-2010. It’s a fantastic resource – more than 3000 leader episodes, and information on their manner of exit and entry. And the conclusion one must draw from examining it is that power is extremely hard to hold on to; a ruler’s hold on power seems to decay in an exponential manner (note I haven’t checked that the decay really is exponential in the technical sense, though I'm thinking of doing that). Over this vast span of time, covering all kinds of political regimes, the half-life of leaders is only about 2 years, or a third of the median authority pattern, as we might have expected from the previous post (though the half-life of leaders is even smaller here):

Yet of course it is the people who beat the odds – those who last much longer than the average leader – the ones who shape social and political life. (There’s an endless parade of mediocrities in the dataset, two-bit prime ministers gone after a few months of ineffectual dabbling and the like).

(But don’t some leaders come back to power after losing it? In fact, the vast majority of leaders only attain power once, and never return to power, though about 100 did manage the feat three or more times. In fact, practice does not help; survival in power only appears to decrease the more previous times the leader had been in power, though note that the uncertainty of the estimates also increases, and one might expect that age would take its toll too).

We are now in a position to extend the analysis in the post below by merging the Archigos and the Polity dataset to calculate the survival curves for leaders conditional on the pattern of executive recruitment. Though I would take these curves with a grain of salt, here are the results:

As expected from the previous post, it’s good to be king – the half-life of absolute kings is about 12 years (and it’s almost always king: there are only 41 female leaders in a 3000 case dataset). Interestingly, a similar result for the half-lives of Chinese emperors is reported here (10 years: Khmaladze,  Brownrigg, and Haywood 2010, ungated) as well as for the half-lives of Roman emperors (11 years: Khmaladze,  Brownrigg, and Haywood 2007, ungated). There is something about the deep structure of monarchies in many different periods and societies, it seems, that points to a half-life in power of about 10-13 years for monarchs. 

More generally, authoritarianism pays in terms of leader tenure, despite the fact that non-competitive regimes do not always last longer than competitive ones. The highest half-lives of leaders beyond monarchs are found in limited elite selection regimes, executive-guided transitions (where non-democratic leaders are changing the rules), and competitive authoritarian regimes; but democracies are more lasting than most of these regimes (except for monarchies; see above).

Another way of looking at this is to calculate what we might call the “personalization quotient” of a regime: divide the half-life of the leader (for a given regime) by the half-life of the regime to get an idea of the percentage of the regime half-life that a leader is expected to last. So a monarch is expected to last about 37% of the half-life his regime (31.86 / 12); this is the most intensely personalized of regimes, as one might have expected given that it is devoted to the maintenance of a family line. The next most personalized regimes are competitive authoritarian regimes (28%), “self-selection” regimes (15%), limited elite selection regimes (16%), and “executive-guided transitions” (40%; this is pretty much by definition, however, so I don't make much of them). A competitive electoral regime has a personalization quotient of 8% - an expected leader half-life of about 2, divided by an expected regime duration of about 17 years. From the point of view of such a leader, it pays to try to move towards a competitive authoritarian regime, and it pays for the leader of a limited elite selection regime to move towards a formal hereditary monarchy (as is happening, in a sense, in North Korea right now, and almost happened in Egypt and Libya). 

But are authoritarian regimes more risky, so that leaders will try to hang on to power more? We can also look at that using the archigos dataset. Though leaders in non-democratic regimes have a slightly higher risk of leaving office with their heads on pitchforks or hanging from lampposts, the vast majority leave by "regular" procedures.  

More, perhaps, could be said. I’ve been wondering, for example, about whether there is a relationship between the breakdown of particular regimes and the tenure of leaders, though I’m not sure how to go about tackling that question. From the point of view of the study of legitimacy, however, what strikes me is the general fragility of patterns of authority and rule: few patterns of authority are expected have half-lives that exceed a single generation, and most don’t last nearly as long, regardless of their “legitimation formula” – heredity, competitive elections, ideology, whatever. Of course, some beat the odds, especially some competitive regimes and some monarchies, and these shape history. But the historical evidence suggests that they are in a sense the exception rather than the rule.

Comparative Political Leader Survival, 1946-2008

After playing around with Jay Ulfelder's data on the survival of democracy in the previous post, it occurred to me that I have not seen survival estimates for leaders in different kinds of regimes like the ones he discusses for democracies. So, in the spirit of exploratory data analysis, here are some graphs using data from the DD dataset of political regimes by Cheibub, Gandhi, and Vreeland, which provides information about regime type, effective heads of government, and leadership tenure for most countries in the world for the period 1946-2008. (Fuller data and methods note at the end of the post).

First, let's look at a simple estimate of leader survival for all (effective) political leaders in all regimes in the post WWII era:

The figure shows an estimate of the proportion of leaders who are expected to still be in power after n years. So, for example, after four years in power, less than half of all leaders are expected to still be in power, and after 20 years less than 10% of all leaders are expected to still be in power; the majority of all leaders last less than 4 years in power, and the vast majority less than 5. [Update: of course, some of these leaders come back to power after a shorter or longer period out of power.] This may be easier to see if we draw the plot on a logarithmic scale:

This looks like a classic "long tail" distribution of a kind often produced by "rich get richer" processes: most leaders don't last in power very long, but those who beat the odds can do very well indeed, as power feeds on itself and leaders become increasingly difficult to dislodge. (I won't say anything about power laws for fear of attracting the ire of the statistical gods). 

Nevertheless, democratic leaders and non-democratic leaders aren't equally successful at hanging on to power:

While the median democratic leader can expect less than 3 years in power, the median autocrat can expect a bit less than 7. And the gap widens with time: less than 8% of all democratic leaders can expect to hang on to power for more than 10 years, but more than 40% of autocrats do, and no democratic leader in the sample has lasted more than 25 years in power (Lynden Pindling of the Bahamas and Eric Williams of Trinidad and Tobago; your mileage may vary as to how democratic you think they were, but that's how they are coded), whereas nearly 20% of autocrats do. This may seem obvious (after all, autocrats typically impose larger barriers to political competition than democratic leaders, and ordinary people face larger obstacles in trying to get rid of them) but it also presents a bit of a puzzle, for democracies are supposed to be more responsive to popular wishes and more legitimate, and dictators are always at risk of being overthrown by their close associates. (For one influential explanation of the observed pattern of survival by Bueno de Mesquita, Smith, Siverson, and Morrow, see here and here). The greater legitimacy of democratic leaders, and their closer connection to popular opinion (to whatever degree: let's not exaggerate, either), does not seem to translate into a surer hold on power. 

Not all autocrats do equally well; absolute monarchs are especially successful at holding on to power:

Though the uncertainty of the survival estimate is larger for monarchs than for other regimes (there are just fewer monarchs in the sample) their advantage is large enough to be noticeable above the noise: nearly 60% of all monarchs can expect to last 20 or more years in power, while only 20% of other autocratic rulers can expect to survive that long, and less than 1% of democratic leaders can hope for such a career. This is another reason to think the Middle Eastern monarchs are probably safer from being overthrown than the leaders of the "republican" regimes, as Victor Menaldo has recently argued. His argument points to specific features of the political culture of these monarchies that enable elites to better monitor and discipline leaders; but other things may be going on as well (monarchs elsewhere in the world also appear to have done well, so whatever enables monarchs in the Middle East to survive appears to also work elsewhere, though admittedly most of the world's absolute monarchs since 1946 have been concentrated in the Middle East). It is also interesting to note that military and civilian dictators do not differ (much) in terms of their survival expectations (the estimates fall within each other's 95% confidence intervals), despite theoretical and empirical work that suggests that military regimes are less stable than civilian dictatorships. (Of course, this could be due to any number of things, including problems with the coding of the data and the fact that the stability of regimes is a different thing from the stability of any given leader's grip on power).

I was also curious to see whether the survival of leaders differs across regions of the world. And at least for non-democratic leaders, that seems to be the case:

There's a lot of uncertainty in these estimates (and I could have made a mistake), but in general it seems to be the case that autocratic leaders have had less success hanging on to power in Latin America, despite the USA's not always benevolent influence in the region. That was surprising to me, so perhaps someone will tell me why this is wrong. By contrast, democratic leaders all have very similar survival expectations all over the world; no evidence of "regional" effects seems evident:

Now that I've mentioned the USA's influence, we might as well look into whether autocrats (or democratic leaders) have had more trouble hanging on to power during or after the cold war. Surprisingly, it seems they have not: leaders in both regimes had the same survival expectations in both periods. But this was tricky to figure out how to calculate, and it is the most likely spot where I might have made a mistake (see sources and methods note below):

Sources and methods. A full description of the DD dataset can be found here, including the criteria it uses for categorizing regimes as democratic or non-democratic and a general defense of its methodological approach. (It used to be possible to download it as well from that page, but the form no longer seems to be working. I've animated the dataset here.) These criteria have been criticized for a variety of reasons, but in general DD does not suffer from worse problems than many of the other common datasets of political regimes (like Polity IV or Freedom House). It is possible that some of the coding decisions they make might influence the estimates of survival presented above, e.g. because they err on the side of classifying some regimes as dictatorships that could have been considered democratic (when there has been no alternation in power). This would tend to bias downward the survival estimates of democratic leaders. At any rate, DD includes information about leaders and their tenure, which is missing in other datasets and makes the data-wrangling easier, though this information is not always complete (there is sometimes more than one leader in a year for a given country, a fact that the dataset must omit, given its country-year resolution) and is not quite in the right format for survival analysis. I thus had to reshape  it (R code and a general description of the process; rank amateurism on display). I created three data files: one for the plots of survival for all leaders and leaders by democracy/non-democracy (ddsurvival.csv); one for the plots of survival by autocratic regime type (ddsurvival2.csv); and one for the plots of survival during and after the cold war (ddcoldwar.csv). (R code for generating all plots is here). These files treat the leader spell as a case; "right censoring" occurs when the leader dies or if the leader is still in power by 2008 (see the DD codebook; the files use a variable called ecens2). Since DD does not distinguish between deaths by natural causes and political assassinations or death in revolution, this introduces a certain amount of bias; in theory, "political" deaths should not result in"censoring" of the data. I should note that the plot of survival by autocratic regime  type does not take into account some cases where "left censoring" occurs (i.e., when a regime starts before 1946), though the number of cases where that is a problem is very small. Finally, there are a small number of repeated cases in ddsurvival.csv and ddcoldwar.csv due to problems guessing the right "entry date" for the leader; these must introduce some small amount of error, though I couldn't possibly say how much or in what direction the bias would work.

How Fragile is Democracy? A Footnote on Jay Ulfelder’s Dilemmas of Democratic Consolidation

Stories about what makes democracy stable tend to take one of two forms. The first stresses socialization, learning, and the gradual development of norms of tolerance for political opposition and alternation in power. On this view, stability usually comes with time, and the breakdown of democracy is to be explained primarily by reference to cultural and normative deficits: corrupt socialization, the emergence or widespread acceptance of anti-democratic ideologies, the weakness of democratic norms of tolerance, and the like. In its simplest form, this view suggests that democracy fails due to a lack of a proper “democratic culture” and/or “inexperience” with democratic institutions. The second kind of story, by contrast, stresses the strategic relationships among major collective actors, like political parties, the military, the government, and foreign powers. On this view, stability emerges only when democracy is a self-enforcing equilibrium (ungated), that is, when all actors find that supporting democratic institutions is their “best response” to the actions of everyone else in light of their own interests, and its breakdown is to be explained primarily by reference to the changing interests and expectations of these actors.

These two types of stories are not wholly incompatible, to be sure: norms can be strategically undermined and manipulated, and an organization’s view of its interests is typically shaped, even constituted, by whatever shared values its members have been socialized into. Strategic equilibria may only be achievable after a period of learning, and the resulting strategic configurations may crystallize into norms. Yet scholars of democratization typically fall on one or the other side of this divide, and the differing stresses they place on normative vs. strategic considerations when explaining the stability or fragility of democracy have important practical implications. Jay Ulfelder’s Dilemmas of Democratic Consolidation: A Game-Theory Approach falls squarely on the “strategic” side of the divide. (Full disclosure: I don’t know Jay personally, but he’s a virtual acquaintance. I enjoy reading his blog and interacting with him online; I have linked to his work before, and he has returned the favour. And while I was writing this post, he cheerfully answered my ignorant questions about his data and models).

Jay identifies three actors as especially relevant to the stability of democracy: the incumbent government (and its key constituencies), opposition forces, and the military. (One might have included foreign powers as well, as some people with similar models of democratic stability do, but simplicity is a virtue in game-theoretic approaches, and anyway the basic framework can easily be extended in that way). The importance of the first two actors is clear: democracy (in a minimal sense, at least; more on this in another post) survives when the government is willing to yield control of the state apparatus to the opposition when it loses an election (it prefers to yield power rather than stage an autogolpe or engage in fraudulent electoral practices), and when the opposition is not tempted to overthrow the government by extra-legal means if it is unable to win an election. The military has independent importance in this framework because, if the government faces substantial opposition mobilization, the military is likely to be the only actor with sufficient organizational capacity to repress it. But this capability, of course, introduces a familiar problem: if the military can repress the opposition, why wouldn’t it overthrow the government as well? A cultural or normative explanation of military self-restraint would stress the development of a particular military culture (professionalism, a strict norm of civilian supremacy); and while such an explanation is certainly part of a sociologically complete answer (even though I do not in general find it convincing), a strategic understanding of motivation suggests that given sufficient incentives, all norms break. One must explain the self-restraint of not only the military but of all relevant actors – their willingness to respect whatever norms of political competition structure the political system – at least partly in terms of how respecting these norms is strategically appropriate for them given their interests (regardless of how these interests come to be constituted in the first place, a question which we leave aside for the moment). If the “best response” (in terms of the protection of their interests) of at least some of these actors to the actions of others is to defect from the norms of political competition, then democracy will not survive. Democratization is not like growing up: democracy can fail even after long experience, if the key actors involved find that in order to protect their important interests their best response to the actions of others is to undermine it.

Given this basic framework, two important questions emerge. First, we would want to know how different regimes affect the interests of particular actors, and how these actors in turn come to understand the ways in which different regimes affect these interests. An answer to this question tells us how the “preferences” of different groups for different kinds of democratic and non-democratic regimes come to be structured, and indicates what factors can change their evaluation of the available possibilities. Jay glosses over this question perhaps too quickly, speaking simply of the “material” interests of the various actors under different regimes, even though his own case narratives later in the book suggest that other kinds of interests – status interests, for example – are also quite important. (Militaries seem to understand their interests in terms of status, in particular). At any rate, the model he develops assumes that the preferences for particular regimes of the key collective actors will vary depending on whether there is open political competition for power, and on whether or not they or their allies are in control of the state. Whatever the regime type, the benefits that come from controlling the state (or having one’s allies control the state) will be partly offset by the expected costs of losing power, though these prospects will differ between regime types; at least in theory, the average costs of losing power in a democracy will tend to be smaller than the costs of losing power in an autocracy, but the probability of losing power might seem to be larger in a democracy (and conversely, for opposition forces, the probability of attaining power might seem to be smaller in an autocratic regime). Changes in the expected benefits of holding power (or having one’s allies hold power) and/or the expected costs of losing it (or having one’s allies lose it) will thus affect the evaluation of different regime types, and hence the preferences of actors for different regime types. Big oil booms or busts in petrostates, changes in the ethnic composition of a population or in the prevalence of identity voting, the availability of rents to allies of the opposition and the government, expected cuts to military budgets or threats to territorial integrity, are all among the sorts of things that should have an impact on whether relevant collective actors prefer democracy to autocracy (and on whether they prefer the opposition or the military to be in control in their disfavoured options). Incidentally, here we have a potential explanation for the fact (documented in the book) that democracy tends to last longer in richer countries: to the extent that poorer countries have more rent-driven economies (economies where wealth depends primarily on control of political power), the costs of losing power will be proportionately larger for the government, and the probability of attaining power proportionately smaller for the opposition, leading to greater incentives to “defect” on all sides - to undermine democracy if you are the government, or to attempt extra-legal seizures of power if you are not.

Second, we want to know what parameters determine whether an actor thinks their best response to the actions of others in light of their interests should be to support democracy or to attempt to undermine it (“stage a coup,” for simplicity), given a set of preferences over regime types. Using a “reduced form” game theoretical model, Jay suggests that the relevant parameters are the degree of uncertainty about the preferences of other actors for different regime types, and their capacities to pull off a coup. (Jay actually distinguishes between the coordination costs of different actors and their capacity for pulling off a coup; but these seem to be entangled with one another, since a collective actor’s capabilities to pull off a coup are greatly influenced by its coordination costs, and it might have simplified his model to have a single parameter summarizing the combined effect of both technical capabilities and costs of coordination.) Generally speaking, the government and the military should have greater capacities to undermine democracy than opposition forces, since the latter are (by definition) shut out from power; and indeed of the 195 episodes of democracy in the 1955-2007 period that Jay identifies, fully 27% ended via  “executive coup” (a shorthand for all the ways in which sitting incumbents can undermine political competition, from the quick autogolpe of a Fujimori to the more drawn-out dismantling of the independence of all institutions of a Chavez or Putin), 21% via classic military coup, and only 2.6% via opposition-led rebellion (44% survived beyond 2007, and about 5% ended in other ways, such as via foreign intervention or the splitting of the country). Nevertheless, militaries and governments are not always capable of pulling off coups due to organizational disarray or other divisions (as in Ukraine in the early 2000s, a case discussed in the book, when the bits of the Soviet army that became the Ukrainian army were in no position to stage a coup despite consistent government attempts to cut its budget and privileges), and opposition forces sometimes have access to considerable resources (e.g., during the coup attempt against Chavez in 2002 the main television stations were in the hands of opposition forces); and capacities can change, sometimes abruptly. (In general, while technical capacities are relatively stable, costs of coordination are not constant or wholly under the control of the relevant forces; relatively insignificant events can suddenly lower or raise them, as when a man setting himself on fire in Tunisia catalyzed protests and collective action that continues to this day. To speak of a “costs of coordination” parameter is merely to summarize a wide array of factors that affect the capacities of groups to engage successfully in risky collective action, a point that I don’t think is sufficiently stressed in the book).

The question of uncertainty is more complicated. Jay argues that even if every relevant collective force prefers democracy, given enough uncertainty about the intentions and capacities of other actors, particular groups may still wish to “strike first” to avoid being dominated by others, regardless of their capacities. If the opposition thinks the government is trying to set up a dictatorship (even if this is not the intention) it may feel that its interests would be better protected by staging a preemptive coup, even if its first preference would be for a democratic regime (this was arguably the case in the 2002 coup against Chavez, as the book notes, though I should note that some of the leaders of the coup might in fact have preferred an autocratic regime). This naturally raises the question of how different actors can credibly signal commitment to a democratic regime, something that is a bit underexplored in the book. For one thing, signals of commitment to democracy are partly tied to changes in capabilities to undermine it: saying that one supports democracy is less credible when one is busy building up ethnic armies, as Jay discusses in the case of the breakdown of democracy in Cyprus in the 1960s. (Oddly, this case does not appear in the dataset in the appendix). Indeed, uncertainty can be induced by well-meaning “democracy aid” that appears to change the relative capacities of actors. For example, aid to democracy-promoting NGOs may make the government feel more threatened by opposition forces, and hence more likely to undermine electoral institutions and harass such organizations in order to prevent a later loss of power (as appears to have been the case, in part, in Russia after the “color revolutions” of the 2000s).

Perhaps the most interesting section of the book is its critique of democracy promotion as a way of "consolidating" democracy. Drawing on work by Carothers, Jay argues that much democracy promotion is insufficiently sensitive to the strategic implications of particular interventions, and too wedded to functionalist assumptions about the proper “components” of democracy. (Some of the arguments here echo Bill Easterly’s critique of development assistance, especially the points about the difficulties of evaluating a lot of “democracy promotion” activities, our lack of knowledge about important aspects of the democratization process, the bureaucratic incentives to measure the effectiveness of democracy promotion by inputs rather than outputs, and the tendency to disregard the wider strategic effects of these interventions on the domestic politics of the target country). It is too easy to give money for “civil society” (in fact, the availability of such money will usually stimulate the creation of organizations with high-sounding names but dubious democratic credentials); it is much more difficult to manage a delicate strategic situation so that all actors end up signalling credible commitments to democratic norms. The book’s framework suggests that investments in institutions that guarantee credibility (like election observation missions, the judiciary, and electoral commissions) are thus better than direct aid to opposition forces or “civil society” promotion in fragile democracies.

Now for some (small) critique. Aside from some quantitative evidence, Jay uses various case studies of democratic breakdown – in Ukraine, Fiji, Cyprus, Venezuela, and Thailand – and survival – in Spain – to illustrate the explanatory power of the basic model. Basically, what he does is to show how if we look at the parameters that the model indicates are “interesting” – the apparent costs and benefits of different regimes for the relevant actors, their signals of commitment to democracy, and their (changing) capacities for staging coups – we can construct narratives that shed light on the process of breakdown (or survival). Despite the fact that I am basically inclined to believe the strategic model of democratization, I confess I was not always entirely convinced by the interpretation of events in these narratives. For example, in the case of Venezuela it appears that the undermining of electoral competition occurred during a boom in oil prices, which increased the government’s capacity for subverting democracy, whereas Jay stresses the previous period of stagnation (which did, to be sure, loosen the commitment of various actors to democracy, and led to a number of unsuccessful coup attempts). And while the narrative Jay constructs can certainly be adjusted to account for this, it may be too easily adjustable, and one may need a clearer picture of how interests are affected by different kinds of regimes to make it fully convincing.  (Including status considerations: the demand for respect was an important ingredient in the rise of Chavez, for example).

Moreover, the evidence presented does not always sufficiently establish how important strategic considerations are relative to alternative explanations stressing norms, learning, and the like. Consider, for example, figure 3.4 from the book:

The figure represents the estimated proportion of democracies that survive after n years since their founding elections (the "Kaplan-Meier" estimate); the dotted red lines indicate that about half of all democracies last 15 years or less. (The dotted black lines represent the 95% confidence interval). Clearly, most democracies don’t last long; but the curve does not seem to indicate that longer-lasting democracies have a relatively constant risk of breakdown (which is what one would expect from a purely strategic model). If learning and other “cultural” considerations were really important, should one expect a slower decay process, or not? (I’m not actually sure). What one would like to know, among other things, is how likely it is that a democracy breaks down given that it has lasted n years, a quantity I would not know how to estimate (and perhaps cannot be cleanly estimated). Similarly, Jay shows that democracies seem to last longer in Eurasia and Latin America than in Africa – by quite substantial margins – but it is unclear that the parameters identified by the model can account for this difference, and the basic survival curves seem at least consistent with various “cultural” stories. Or consider the following figure, which I’ve produced using the data in the appendix (it's not actually in the book):

If I haven’t made any obvious mistakes, the figure suggests that most democracies last longer on their later attempts than on their first attempt. (So Egypt and Tunisia are not likely to end democratic 10 years from now, even if they manage a relatively successful transition now, but might have better luck in a later attempt). But given the book’s model, this is puzzling: why is there a “learning” effect at all? Why should the strategic situation “improve” on the second attempt at democracy?

It is also interesting to look at countries that have had lots of democratic spells (and hence lots of breakdowns). From the data in the book, 9 countries have had 4 or more “spells” of democracy: Greece, Argentina, Syria, Peru, Turkey, Ghana, Peru, Sierra Leone, and Ecuador (Argentina is the world champion, with 7 spells and 6 breakdowns). Why have democratic regimes in these countries been so unstable? From the model in the book, one would expect that some features of the state would either impose major costs on some actors if they accepted democracy; make their capacities to undermine it (or demand it) fluctuate widely; and/or make it difficult for credible commitments to democracy to be sustained (leading to a great degree of uncertainty about the intentions of major actors). Are these features especially pronounced in these countries, relative to others? Or is the degree of political conflict over regimes in these countries to be explained in other ways? Inquiring minds want to know.

Anyway, I enjoyed the book and recommend it to anyone interested in democratization. Also, if you have made it this far you should definitely read Jay’s blog.
