摘要：We consider general Bayesian persuasion problems where the receiver's utility is single-peaked in a one-dimensional action. We show that a signal that pools at most two states in each realization is always optimal and that such pairwise signals are the only solutions under a nonsingularity condition on utilities. Our core results provide conditions under which the induced receiver action is single-dipped or single-peaked on each set of nested signal realizations. We also provide conditions for...

摘要：In a randomized controlled trial, we test whether removal of a barrier to exercise can improve academic performance. We find strong support for this hypothesis: University students who were provided with a free gym card exercised more and had a significant improvement in academic performance. The treated students were less likely to drop out of classes and to fail at the exam. We provide evidence showing that exercise caused a healthier lifestyle and increased perceived self-control, which ult...

摘要：For governments procuring innovation, one choice is whether to specify desired products (a conventional approach) or allow firms to suggest ideas (an open approach). Using a US Air Force R&D grant program where open and conventional competitions were held simultaneously, we find that open awards increase both commercial innovation and technology adoption by the military. In contrast, conventional awards have no positive effects on new technology but do create more program lock-in. We present e...

摘要：We study optimal adversarial information design in a dynamic regime change game. Agents decide when to attack, if at all. We assume (1) delay incurs a continuous cost and (2) agents doubt the correctness of their actions. The game may end in a disaster due to weak fundamentals or panic-agents attacking despite sound fundamentals. We propose a timely disaster alert that promptly warns about impending disasters, making waiting for and following the alert the unique rationalizable strategy, there...

摘要：This paper examines the nature of entrepreneurship using a novel panel dataset based on US Internal Revenue Service data. We analyze income growth trajectories and the determinants of entrepreneurial choice for business owners. Compared with prior household survey-based studies, we find that self-employed individuals have significantly higher average incomes and steeper income growth than their wage-earning matched peers. Contrary to survey evidence, we find a limited role for nonpecuniary mot...

摘要：The US government is the dominant supplier of global safe assets and faces a downward-sloping demand for its debt. We develop a model of the global economy in which US public debt generates special value for holders, endowing the US government with market power. We use variations in demand elasticities during high- and low-volatility regimes to distinguish this model from a price-taking benchmark and find that the data reject price-taking behavior in favor of the US government exploiting marke...

摘要：Since the 1980s, the United States has experienced both an increase in income inequality and a rise in residential segregation by income. We develop a general equilibrium model with residential choice, where segregation and inequality amplify each other because of a local spillover affecting educational returns. We calibrate the model to a representative US metro in 1980 and use the micro estimates of neighborhood exposure effects in Chetty and Hendren (2018b) to discipline the spillover. We t...

摘要：We analyze a nonlinear pricing model where the seller controls both product pricing (screening) and buyer information about their own values (persuasion). We prove that the optimal mechanism always consists of finitely many signals and items, even with a continuum of buyer values. The seller optimally pools buyer values and reduces product variety to minimize informational rents. We show that value pooling is optimal even for finite value distributions if their entropy exceeds a critical thres...

摘要：During adolescence, peer interactions become increasingly central to children's development, whereas the direct influence of parents wanes. Nevertheless, parents can continue to exert leverage by shaping their children's peer groups. We construct and estimate a model of parenting with peer and neighborhood effects where parents intervene in peer formation and show that the model captures empirical patterns of skill accumulation, parenting style, and peer characteristics among US high school st...

摘要：Using a model of maternal labor supply and investment in children, this paper synthesizes the findings from three separate welfare reform experiments across six sites. The proposed model maps variation in experimental design to parameters that define labor supply behavior, childcare use, and the importance of money and childcare arrangements in the development of child skills. The estimation procedure-which aggregates available evidence to identify the model's key causal parameters-amounts to ...
