International peacebuilding can improve the prospects that a civil war will be resolved. Although peacebuilding strategies must be designed to address particular conflicts, broad parameters that fit most conflicts can be identified. Strategies should address the local roots of hostility, the local capacities for change, and the (net) specific degree of international commitment available to assist sustainable peace. One can conceive of these as the three dimensions of a triangle whose area is the “political space”—or effective capacity—for building peace. We test these propositions with an extensive data set of 124 post–World War II civil wars and find that multilateral, United Nations peace operations make a positive difference. UN peacekeeping is positively correlated with democratization processes after civil war, and multilateral enforcement operations are usually successful in ending the violence. Our study provides broad guidelines for designing the appropriate peacebuilding strategy, given the mix of hostility, local capacities, and international capacities.

Building on a growing literature in international political science, I reexamine the traditional liberal claim that governments founded on a respect for individual liberty exercise “restraint” and “peaceful intentions” in their foreign policy. I look at three distinct theoretical traditions of liberalism, attributable to three theorists: Schumpeter, a democratic capitalist whose explanation of liberal pacifism we often invoke; Machiavelli, a classical republican whose glory is an imperialism we often practice; and Kant, a liberal republican whose theory of internationalism best accounts for what we are. Despite the contradictions of liberal pacifism and liberal imperialism, I find, with Kant and other democratic republicans, that liberalism does leave a coherent legacy on foreign affairs. Liberal states are different. They are indeed peaceful. They are also prone to make war. Liberal states have created a separate peace, as Kant argued they would, and have also discovered liberal reasons for aggression, as he feared they might. I conclude by arguing that the differences among liberal pacifism, liberal imperialism, and Kant's internationalism are not arbitrary. They are rooted in differing conceptions of the citizen and the state.

Exposure to conflicting political viewpoints is widely assumed to benefit the citizens of a democratic polity. Nonetheless, the benefits of exposure to heterogeneous political viewpoints have yet to be demonstrated empirically. Drawing on national survey data that tap characteristics of people's political discussion networks, I examine the impact of heterogeneous networks of political discussion on individuals' awareness of legitimate rationales for oppositional viewpoints, on their awareness of rationales for their own viewpoints, and on levels of political tolerance. Finally, utilizing a laboratory experiment manipulating exposure to dissonant and consonant political views, I further substantiate the causal role of cross-cutting exposure in fostering political tolerance.

Despite repeated calls for the use of “mixed methods” in comparative analysis, political scientists have few systematic guides for carrying out such work. This paper details a unified approach which joins intensive case-study analysis with statistical analysis. Not only are the advantages of each approach combined, but also there is a synergistic value to the nested research design: for example, statistical analyses can guide case selection for in-depth research, provide direction for more focused case studies and comparisons, and be used to provide additional tests of hypotheses generated from small-N research. Small-N analyses can be used to assess the plausibility of observed statistical relationships between variables, to generate theoretical insights from outlier and other cases, and to develop better measurement strategies. This integrated strategy improves the prospects of making valid causal inferences in cross-national and other forms of comparative research by drawing on the distinct strengths of two important approaches.

“In God We Trust: Everyone Else Pays Cash.” America's political leaders should not pretend to godliness; no one will be fooled. According to prestigious biennial national surveys, the government's credit rating has steadily declined as a result of a disastrous foreign investment and growing consumer resistance to its “line” of products. Neither the country's present management nor its most prominent rivals inspire public confidence. How, then, can the political system rebuild its depleted reserves of political trust, the basis of future growth and stability? Will “one good season,” better advertising, new blood in the boardroom or product innovation be sufficient? Or is a drastic restructuring of the regime's organization and operating procedures the only alternative to liquidation?

Arthur Miller's article, “Political Issues and Trust in Government: 1964–70” makes an important contribution to our understanding of the sharp increase in political cynicism among the American public. Miller evokes the language of the corporation balance-sheet and the imagery of Executive Suite by suggesting that the cumulative outcome of exchanges between political authorities on the one hand and citizens on the other determines the level of public trust in government. Political elites “produce” policies; in exchange, they receive trust from citizens satisfied with these policies and cynicism from those who are disappointed. Since Miller defines both policy satisfaction and political trust in attitudinal terms, the exchange transactions he records are purely psychological in nature. Operationally, dissatisfied respondents are those whose own policy preferences are discrepant with their perceptions of the positions advocated by the party controlling the presidency.

Using 1987 national sample survey data that included a large black oversample, we reexamine black-white differences in sociopolitical participation. We hypothesized that increases in black empowerment would affect the level of black sociopolitical participation and change the nature of black-white differences in political behavior. The results show that blacks in high-black-empowerment areas—as indicated by control of the mayor's office—are more active than either blacks living in low-empowerment areas or their white counterparts of comparable socioeconomic status. Furthermore, the results show that empowerment influences black participation by contributing to a more trusting and efficacious orientation to politics and by greatly increasing black attentiveness to political affairs. We discuss the results' implications for theoretical interpretations of when and why black sociopolitical behavior differs from that of whites.

This paper reframes our inquiry into voter turnout by making aging the lens through which the traditional resource and cost measures of previous turnout research are viewed, thereby making three related contributions. (1) I offer a developmental theory of turnout. This framework follows from the observation that most citizens are habitual voters or habitual nonvoters (they display inertia). Most young citizens start their political lives as habitual nonvoters but they vary in how long it takes to develop into habitual voters. With this transition at the core of the framework, previous findings concerning costs and resources can easily be integrated into developmental theory. (2) I make a methodological contribution by applying latent growth curve models to panel data. (3) Finally, the empirical analyses provide the developmental theory with strong support and also provide a better understanding of the roles of aging, parenthood, partisanship, and geographic mobility.

Suicide terrorism is rising around the world, but the most common explanations do not help us understand why. Religious fanaticism does not explain why the world leader in suicide terrorism is the Tamil Tigers in Sri Lanka, a group that adheres to a Marxist/Leninist ideology, while existing psychological explanations have been contradicted by the widening range of socio-economic backgrounds of suicide terrorists. To advance our understanding of this growing phenomenon, this study collects the universe of suicide terrorist attacks worldwide from 1980 to 2001, 188 in all. In contrast to the existing explanations, this study shows that suicide terrorism follows a strategic logic, one specifically designed to coerce modern liberal democracies to make significant territorial concessions. Moreover, over the past two decades, suicide terrorism has been rising largely because terrorists have learned that it pays. Suicide terrorists sought to compel American and French military forces to abandon Lebanon in 1983, Israeli forces to leave Lebanon in 1985, Israeli forces to quit the Gaza Strip and the West Bank in 1994 and 1995, the Sri Lankan government to create an independent Tamil state from 1990 on, and the Turkish government to grant autonomy to the Kurds in the late 1990s. In all but the case of Turkey, the terrorist political cause made more gains after the resort to suicide operations than it had before. Thus, Western democracies should pursue policies that teach terrorists that the lesson of the 1980s and 1990s no longer holds, policies which in practice may have more to do with improving homeland security than with offensive military action.I thank Robert Art, Mia Bloom, Steven Cícala, Alex Downs, Daniel Drezner, Adria Lawrence, Sean Lynn-Jones, John Mearsheimer, Michael O'Connor, Sebastian Rosato, Lisa Weeden, the anonymous reviewers, and the members of the program on International Security Policy at the University of Chicago for their superb comments.

Does incivility in political discourse have adverse effects on public regard for politics? If so, why? In this study we present a theory suggesting that when viewers are exposed to televised political disagreement, it often violates well-established face-to-face social norms for the polite expression of opposing views. As a result, incivility in public discourse adversely affects trust in government. Drawing on three laboratory experiments, we find that televised presentations of political differences of opinion do not, in and of themselves, harm attitudes toward politics and politicians. However, political trust is adversely affected by levels of incivility in these exchanges. Our findings suggest that the format of much political television effectively promotes viewer interest, but at the expense of political trust.

The Chinese government has long been suspected of hiring as many as 2 million people to surreptitiously insert huge numbers of pseudonymous and other deceptive writings into the stream of real social media posts, as if they were the genuine opinions of ordinary people. Many academics, and most journalists and activists, claim that these so-called 50c party posts vociferously argue for the government’s side in political and policy debates. As we show, this is also true of most posts openly accused on social media of being 50c. Yet almost no systematic empirical evidence exists for this claim or, more importantly, for the Chinese regime’s strategic objective in pursuing this activity. In the first large-scale empirical analysis of this operation, we show how to identify the secretive authors of these posts, the posts written by them, and their content. We estimate that the government fabricates and posts about 448 million social media comments a year. In contrast to prior claims, we show that the Chinese regime’s strategy is to avoid arguing with skeptics of the party and the government, and to not even discuss controversial issues. We show that the goal of this massive secretive operation is instead to distract the public and change the subject, as most of these posts involve cheerleading for China, the revolutionary history of the Communist Party, or other symbols of the regime. We discuss how these results fit with what is known about the Chinese censorship program and suggest how they may change our broader theoretical understanding of “common knowledge” and information control in authoritarian regimes.

We examine formally the link between domestic political institutions and policy choices in the context of eight empirical regularities that constitute the democratic peace. We demonstrate that democratic leaders, when faced with war, are more inclined to shift extra resources into the war effort than are autocrats. This follows because the survival of political leaders with larger winning coalitions hinges on successful policy. The extra effort made by democrats provides a military advantage over autocrats. This makes democrats unattractive targets, since their institutional constraints cause them to mobilize resources for the war effort. In addition to trying harder, democrats are more selective in their choice of targets. Because defeat is more likely to lead to domestic replacement for democrats than for autocrats, democrats only initiate wars they expect to win. These two factors lead to the interaction between polities that is often referred to as the democratic peace.

A large body of scholarship finds a negative relationship between natural resources and democracy. Extant cross-country regressions, however, assume random effects and are run on panel datasets with relatively short time dimensions. Because natural resource reliance is not an exogenous variable, this is not an effective strategy for uncovering causal relationships. Numerous sources of bias may be driving the results, the most serious of which is omitted variable bias induced by unobserved country-specific and time-invariant heterogeneity. To address these problems, we develop unique historical datasets, employ time-series centric techniques, and operationalize explicitly specified counterfactuals. We test to see if there is a long-run relationship between resource reliance and regime type within countries over time, both on a country-by-country basis and across several different panels. We find that increases in resource reliance are not associated with authoritarianism. In fact, in many specifications we generate results that suggest a resource blessing.

For the most part, scholars who study American political parties in the electorate continue to characterize them as weak and in decline. Parties on the elite level, however, have experienced a resurgence over the last two decades. Such a divergence between elite behavior and mass opinion is curious, given that most models of public opinion place the behavior of elites at their core. In fact, I find that parties in the electorate have experienced a noteworthy resurgence over the last two decades. Greater partisan polarization in Congress has clarified the parties’ ideological positions for ordinary Americans, which in turn has increased party importance and salience on the mass level. Although parties in the 1990s are not as central to Americans as they were in the 1950s, they are far more important today than in the 1970s and 1980s. The party decline thesis is in need of revision.

What is the political legacy of violent conflict? I present evidence for a link from past violence to increased political engagement among excombatants. The evidence comes from northern Uganda, where rebel recruitment generated quasiexperimental variation in who was conscripted by abduction. Survey data suggest that abduction leads to substantial increases in voting and community leadership, largely due to elevated levels of violence witnessed. Meanwhile, abduction and violence do not appear to affect nonpolitical participation. These patterns are not easily explained by conventional theories of participation, including mobilization by elites, differential costs, and altruistic preferences. Qualitative interviews suggest that violence may lead to personal growth and political activation, a possibility supported by psychological research on the positive effects of traumatic events. Although the generalizability of these results requires more evidence to judge, the findings challenge our understanding of political behavior and point to important new avenues of research.

This article develops a model for analyzing social identity and applies it to the political economy of income redistribution, focusing on class and national identities. The model attempts to distill major findings in social psychology into a parsimonious statement of what it means to identify with a group and what factors determine the groups with whom people identify. It then proposes an equilibrium concept where both identities and behavior are endogenously determined. Applying this model to redistribution helps explain three empirical patterns in modern democracies. First, national identification is more common among the poor than among the rich. Second, national identification tends to reduce support for redistribution. Third, across democracies there is a strong negative relationship between the prevalence of national identification and the level of redistribution. The model further points to national eminence, national threats, and diversity within the lower class as factors that can reduce redistribution.

One of the most contested questions in the social sciences is whether people behave rationally. A large body of work assumes that individuals do in fact make rational economic, political, and social decisions. Yet hundreds of experiments suggest that this is not the case. Framing effects constitute one of the most stunning and influential demonstrations of irrationality. The effects not only challenge the foundational assumptions of much of the social sciences (e.g., the existence of coherent preferences or stable attitudes), but also lead many scholars to adopt alternative approaches (e.g., prospect theory). Surprisingly, virtually no work has sought to specify the political conditions under which framing effects occur. I fill this gap by offering a theory and experimental test. I show how contextual forces (e.g., elite competition, deliberation) and individual attributes (e.g., expertise) affect the success of framing. The results provide insight into when rationality assumptions apply and, also, have broad implications for political psychology and experimental methods.

Both implicit democratic norms and the reconstructions provided by theorists of rational choice suggest that issue voters are more sophisticated–educated, informed, and active in politics–than other voters. But some issues are clearly more difficult than others, and the voters who respond to “hard” and “easy” issues, respectively, are assumed to differ in kind. We propose the hypothesis that “easy-issue” voters are no more sophisticated than non-issue voters, and this is found to be the case. The findings suggest a reevaluation of the import of rising and falling levels of issue voting and suggest a prominent role for “easy” issues in electoral realignments.

Do voters effectively hold elected officials accountable for policy decisions? Using data on natural disasters, government spending, and election returns, we show that voters reward the incumbent presidential party for delivering disaster relief spending, but not for investing in disaster preparedness spending. These inconsistencies distort the incentives of public officials, leading the government to underinvest in disaster preparedness, thereby causing substantial public welfare losses. We estimate that $1 spent on preparedness is worth about $15 in terms of the future damage it mitigates. By estimating both the determinants of policy decisions and the consequences of those policies, we provide more complete evidence about citizen competence and government accountability.

Preferences come from the most ubiquitous human activity: living with other people. Support for and opposition to different ways of life, the shared values legitimating social relations (here called cultures) are the generators of diverse preferences. After discussing why it is not helpful to conceive of interests as preferences or to dismiss preference formation as external to organized social life, I explain how people are able to develop many preferences from few clues by using their social relations to interrogate their environment. The social filter is the source of preferences. I then argue that culture is a more powerful construct than conceptual rivals: heuristics, schemas, ideologies. Two initial applications—to the ideology of the left-right distinctions and to perceptions of danger—test the claim that this theory of how individuals use political cultures to develop their preferences outperforms the alternatives.

Contemporary research on civil war has largely dismissed the role of political and economic grievances, focusing instead on opportunities for conflict. However, these strong claims rest on questionable theoretical and empirical grounds. Whereas scholars have examined primarily the relationship between individual inequality and conflict, we argue that horizontal inequalities between politically relevant ethnic groups and states at large can promote ethnonationalist conflict. Extending the empirical scope to the entire world, this article introduces a new spatial method that combines our newly geocoded data on ethnic groups’ settlement areas with spatial wealth estimates. Based on these methodological advances, we find that, in highly unequal societies, both rich and poor groups fight more often than those groups whose wealth lies closer to the country average. Our results remain robust to a number of alternative sample definitions and specifications.
