Journal Article
We investigate the effect of individual exposure to communism on support for democracy and capitalism. We examine whether this effect varies across different types of communism, at different periods of people's lives, in different countries, and across different types of individuals. To do so, we propose a modified approach to solving the APC…
Journal Article
We consider a class of dynamic collective action problems in which either a single principal or two competing principals vie for the sup-port of members of a group. We focus on the dynamic problem that emerges when agents negotiate and commit their support to princi-pals sequentially. We show that competition reduces agents' welfare with public…
Journal Article
We use a revealed preference approach to disentangle conformity, an intrinsic taste to follow others, from information-driven herding. We provide ob- servations from a series of sequential decision-making experiments in which sub- jects choose the type of information they observe before making their decision. Namely, subjects choose between…
Journal Article
This paper examines the institutional determinants of discipline in legislative parties. The model formalizes the tradeoff between resources at the leader's discretion, and the leader's need to maintain a minimum level of support to continue leading. The value of the leader's promises of future benefits is here endogenously determined by the…
Journal Article

Some private-monitoring games, that is, games with no public histories, can have histories that are almost public. These games are the natural result of perturbing public monitoring games towards private monitoring. We explore the extent to which it is possible to coordinate continuation play in such games. It is always possible to coordinate…

Journal Article
Corruption is usually depicted in one of two ways: as stemming from a lack of government accountability, or from a lack of capacity. Neither depiction predicts that the structure of institutions meant to control corruption should vary across autocratic regimes. If corruption results from moral hazard between politicians and citizens, then all…
Journal Article
Although scholars of international security share a skepticism for the extent to which agreements can be externally enforced, much existing game-theoretic work involves strong forms of commitment. Building on the canonical model of crisis bargaining, this article analyzes the role of two forms of commitment in bargaining: the ability to commit to…
Journal Article

We present a dynamic model of sequential information acquisition by a heterogeneous committee. At each date, agents decide whether to vote to adopt one of two alternatives or continue to collect more information. The process stops when a qualified majority vote for an alternative. Three main insights emerge from our analysis and are consistent…

Journal Article
We analyze a model of jury decision making in which jurors deliberate before casting their votes. We consider a wide range of voting institutions and show that deliberations render these equivalent with respect to the sequential equilibrium outcomes they generate. In particular, in the context of a jury setup, all voting rules excluding the two…
Journal Article
Most existing work on the demand for health insurance focuses on employees' decisions to enroll in employer-provided plans. Yet any attempt to achieve universal coverage must focus on the uninsured, the vast majority of whom are not offered employer-sponsored insurance. In the summer of 2008, we conducted a survey experiment to assess the…
Journal Article
Existing research suggests that democracy fosters economic globalization by promoting trade liberalization in the developing world. We argue that democracy in developing countries generates a “skill bias” in trade protection where democratic incumbents have incentives to increase tariffs on high skilled goods but reduce trade barriers on low…
Journal Article
In "The Strategic Logic of Suicide Terrorism," Robert Pape (2003) presents an analysis of his suicide terrorism data. He uses the data to draw inferences about how territorial occupation and religious extremism affect the decision of terrorist groups to use suicide tactics. We show that the data are incapable of supporting Pape's conclusions…
Journal Article
We analyze a model of diffusion on social networks. Agents are connected according to an undirected graph (the network) and choose one of two actions (e.g., either to adopt a new behavior or technology or not to adopt it). The return to each of the actions depends on how many neighbors an agent has, which actions the agent's neighbors choose, and…
Journal Article
Increasingly in U.S. public insurance programs, the state finances and regulates competing, capitated private health plans but does not itself directly insure beneficiaries through a public fee-for-service (FFS) plan. We develop a simple model of risk-selection in such settings. Capitation incentivizes insurers to retain low-cost clients and thus…
Journal Article
There are two fundamentally different views of the role of elections in policy formation. In one view, voters can affect candidates' policy choices: competition for votes induces politicians to move toward the center. In this view, elections have the effect of bringing about some degree of policy compromise. In the alternative view, voters merely…
Journal Article
Retrospective voting models assume that offering more information to voters about their incumbents' performance strengthens electoral accountability. However, it is unclear whether incumbent corruption information translates into higher political participation and increased support for challengers. We provide experimental evidence that such in-…
Journal Article
Both pundits and scholars have blamed increasing levels of partisan conflict and polarization in Congress on the effects of partisan gerrymandering. We assess whether there is a strong causal relationship between congressional districting and polarization. We find very little evidence for such a link. First, we show that congressional polarization…
Journal Article
Medicaid programs increasingly finance competing, capitated managed care plans rather than administering fee-for-service (FFS) programs. We study how the transition from FFS to managed care affects high- and low-cost infants (blacks and Hispanics, respectively). We find that black-Hispanic disparities widen—e.g., black mortality and preterm birth…
Journal Article
This article investigates whether the death penalty encourages defendants charged with potentially capital crimes to plead guilty in exchange for lesser sentences. I exploit a natural experiment in New York State: the 1995 reinstatement of capital punishment, coupled with the public refusal of some prosecutors to pursue death sentences (N.Y. Penal…
Journal Article
Left turn: how liberal media bias distorts the American mind by Tim Groseclose. New York: St. Martin's Press, 2011. 304p. Reprinted by permission of Cambridge University Press. An electronic version of this article can be accessed via the internet at http://journals.cambridge.org
Journal Article
Economic impacts of unionization on employers are difficult to estimate in the absence of large, representative data on establishments with union status information. Estimates are also confounded by selection bias, because unions could organize at highly profitable enterprises that are more likely to grow and pay higher wages. Using multiple…
Journal Article
I present key ideas and results from recent work incorporating " motivated " belief distortions into Economics, both at the individual level (overconfidence, wishful thinking, willful blindness) and at the social one (groupthink, team morale, market exuberance and crises). To do so I develop a flexible model that unifies much of this line of…
Journal Article
This article argues that the policy uncertainty generated by elections encourages private actors to delay investments that entail high costs of reversal, creating pre-election declines in the associated sectors. Moreover, this incentive depends on the competitiveness of the race and the policy differences between the major parties/candidates…
Journal Article
The number of prisoners incarcerated on drug-related offenses rose 15-fold between 1980 and 2000. This paper provides the first systematic empirical analysis of the implications of that dramatic shift in public policy. We estimate that cocaine prices are 5-15% higher today as a consequence of increases in drug punishment since 1985, presumably…
Journal Article
We study games with strategic complementarities, arbitrary numbers of players and actions, and slightly noisy payoff signals. We prove limit uniqueness: as the signal noise vanishes, the game has a unique strategy profile that survives iterative dominance. This generalizes a result of Carlsson and van Damme (Econometrica 61 (1993) 989-1018) for…
