摘要：We study the design of voting rules for committees representing heterogeneous groups (countries, states, districts) when cooperation among groups is voluntary. While efficiency recommends weighting groups proportionally to their stakes, we show that accounting for participation constraints entails overweighting some groups, those for which the incentive to cooperate is the lowest. When collective decisions are not enforceable, cooperation induces more stringent constraints that may require gra...

摘要：We experimentally examine private information and communication in a public goods environment with uncertain returns. We consider a common-value public goods game in which the return to contribution is either high or low. Before contributing, three players observe private signals correlated with the return and send cheap talk messages to one another. There are social gains from truthfulness, but a private incentive to exaggerate. We compare treatments with and without cheap talk, finding that ...

摘要：This paper proposes a novel way of distinguishing whether a person is naive or sophisticated about her own dynamic inconsistency using only her task-completion behavior. It shows that adding an unused extra opportunity to complete a task can lead a naive (but not a sophisticated) person to complete it later and can lead a sophisticated (but not a naive) person to complete the task earlier. These results provide a framework for revealing preference and sophistication types from behavior in a ge...

摘要：This paper considers time exchanges via a common platform (e.g., markets for exchanging time units, positions at education institutions, and tuition waivers). There are several problems associated with such markets, e.g., unbalanced outcomes, coordination problems, and inefficiencies. We model time exchanges as matching markets and construct a non-manipulable mechanism that selects an individually rational and balanced allocation that maximizes exchanges among the participating agents (and tho...

摘要：A principal owns a firm, hires an agent of uncertain productivity, and designs a dynamic policy for evaluating his performance. The agent observes ongoing evaluations and decides when to quit. When not quitting, the agent is paid a wage that is linear in his expected productivity; the principal claims the residual performance. After quitting, the players secure fixed outside options. I show that equilibrium is Pareto efficient. For a broad class of performance technologies, the equilibrium wag...

摘要：Motivated by recent antitrust cases in markets with zero-pricing, we develop a leverage theory of tying in two-sided markets. In the presence of the nonnegative price constraint, the Chicago school critique of tie-ins fails to hold. In the independent products case, tying provides a mechanism to circumvent the constraint in the tied market without inviting aggressive responses by the rival firm. In the complementary products case, the price squeeze mechanism cannot be used to extract surplus f...

摘要：We present a strategic network formation model based on membership in clubs. Individuals choose affiliations. The set of all memberships induces a weighted network where two individuals are directly connected if they share a club. Two individuals may also be indirectly connected using multiple memberships of third parties. Individuals gain from their position in the induced network and pay membership fees. We study the club congestion model where the weight of a link decreases with the size of...

摘要：We study efficient exclusion policies in a canonical credit model that features both exogenous and strategic default along the equilibrium path. Policies that maximize welfare in a stationary equilibrium implement exclusion for a finite and deterministic number of periods following default. Front-loading exclusion makes the mass of socially valuable transactions as high as it can be in steady state. Less intuitively, doing so also maximizes the average welfare of excluded agents in equilibrium...

摘要：We develop a model wherein concerns about prosecutor quality reduce the willingness of witnesses to cooperate with prosecutors. This causes an increase in the crime rate and in wrongly convicted innocent defendants. Because citizens are taxpayers and may be victims, perpetrators, witnesses, or falsely accused defendants, they care about the prosecutor's quality. They update beliefs about this quality based on the disposition of cases. If the prosecutor's believed quality falls below a threshol...

摘要：American industries have grown more concentrated over the last 40 years. In the absence of productivity innovation, this should lead to price hikes and output reductions, decreasing consumer welfare. With US census data from 1972 to 2012, I use price data to disentangle revenue from output. Industry-level estimates show that concentration increases are positively correlated to productivity and real output growth, uncorrelated with price changes and overall payroll, and negatively correlated wi...
