摘要：We test the touchstones of economic rationality-utility maximization, stochastic dominance, and expected-utility maximization-of elite students in the U.S. and in Africa. The choices of most students in both samples are generally rationalizable, but the U.S. students' scores are substantially higher. Nevertheless, the development gap in economic rationality in incentivized risk choices between these future elites is much smaller than the difference in performance on a non-incentivized canonica...

摘要：We develop index and degree theories for extensive form games allowing the identification of equilibria that are robust to payoff perturbations directly from the extensive form. Our approach is based on index and degree theories for games where the strategy sets are polytopes (and not necessarily simplices) and payoff functions are multiaffine. Polytope strategy sets arise naturally from topologically identifying equivalent mixed strategies of a normal form game.& COPY; 2023 Elsevier Inc. All ...

摘要：An increasing number of studies call into question the external validity of social preference games. In this paper, we show that these games have a low correlation with single pro-social behaviors in the field, but this correlation can be substantially increased by aggregating behaviors to reduce measurement error. We tracked people's daily pro-social behaviors for 14 days using a day reconstruction method; the same people played three different social preference games on seven different occas...

摘要：Strategic complementarities influence various social and economic activities. This study introduces a model to design a weighted and directed complementarity network to achieve a planner's objectives. The network represents the direction and intensity of complementarities between agents, influencing their best-responses to one another and determining equilibrium efforts. The planner's objective function can be convex, as commonly assumed in prior research, or arbitrarily concave to represent s...

摘要：A principal wants to procure multiple homogeneous units from finitely many agents. Each agent has an increasing and convex cost function, whose exact shape is unknown to the principal. Utility is quasilinear in money. We study which mechanisms are strategy -proof and robust to collusion, both when the agents can exchange money and physical units (reallocation-proofness) and when they cannot (group strategy-proofness). To achieve reallocation-proofness, the principal must offer the agents a fix...

摘要：We study the dynamics of strategic choice in an environment where payoffs are perturbed by strategy-specific noise and strategy revision is governed by the simple proportional imitation protocol. Applying the stochastic replicator dynamic to a two-by-two symmetric game, we derive the steady-state frequencies of the strategies and show that the dominated strategy can persist in equilibrium if the variance of the payoff shocks exceeds a critical value. Additionally, the rate of decay of the domi...

摘要：We introduce an equivalent definition for robust implementation, termed s-rationalizable implementation. We show that s-rationalizable implementation implies rationalizable implementation (Bergemann and Morris, 2011) and is implied by wr-implementation by static mechanisms (Muller, 2020).

摘要：Under majoritarian election systems, securing the participation and representation of minorities remains an open problem, made salient in the US by its history of voter suppression. One remedy recommended by the courts is the adoption of Cumulative Voting (CV) in multi-member districts: each voter has as many votes as open positions but can cumulate votes on as few candidates as desired. Historical experiences are promising but also reflect episodes of minority activism. We present the results...

摘要：We investigate self-serving belief distortion about dominant norms of honesty. Consider an environment where the subject can earn a monetary reward by lying. In contrast to the existing literature on motivated beliefs, we do not focus on distortion in one dimension alone, but instead consider beliefs in two dimensions: empirical (what other people do) and normative (what other people approve of). Our experimental findings are consistent with the predictions of a dual-self model in which condit...

摘要：In this paper we review, upgrade, and synthesize existing models from evolutionary game theory, all of which aim at explaining human behaviour in the ultimatum game. Our new and improved versions of Gale et al. (1995), Nowak et al. (2000), and Rand et al. (2013) avoid shortcomings that the original versions have, one of which is that the results in the first and the last are driven by bias in the mutations. We also compare the predictions of these three models with the existing experimental ev...
