摘要：This paper studies the diffusion process of two complementary technologies among people who are connected through a social network. It characterizes adoption rates over time for different initial allocations and network structures. In doing so, we provide some microfoundations for the stochastic formation of consideration sets. We are particularly interested in the following question: suppose we want to maximize technology diffusion and have a limited number of units of each of the two technol...

摘要：Revealed preference restrictions are increasingly used to predict demand behavior at new budgets of interest and as shape restrictions in nonparametric estimation exercises. However, the restrictions imposed are not sufficient for rationality when predictions are made at multiple budgets. 1 highlight the non-convexities in the set of predictions that arise when making multiple predictions. 1 develop a mixed integer programming characterization of the problem that can be used to impose rational...

摘要：In many contests in economic and political life, both all-pay and winner-pay expenditures matter for winning. This paper studies such hybrid contests under symmetry and asymmetry. The symmetric model assumes very little structure but yields a simple closed-form solution. More contestants tend to lead to substitution toward winner-pay investments, and total expenditures are always lower than in the corresponding all-pay contest. With a biased decision process and two contestants, the favored co...

摘要：Since Telser (1960), there is a well-established argument that a competitive market will not provide service due to freeriding. We show that with search frictions, the market may well provide service if the cost of doing so is not too large. Any market equilibrium with service provision has two or more firms providing service, implying overprovision of service as the social optimum mandates at most one service provider Firms that provide service and those that do not can coexist, where consume...

摘要：This paper studies the optimal design of dynamic research contests. We introduce interim transfers, which are paid in every period while the contest is ongoing, to an otherwise standard setting. We show that a contest where (i) the principal can stop the contest in any period, (ii) a constant interim transfer is paid to agents in each period while the contest is ongoing, and (iii) a final prize is paid once the principal stops the contest, is optimal for the principal and implements the first-...

摘要：We present revealed-preference characterizations of the most common models of intertemporal choice: the model of exponentially discounted concave utility, and some of its generalizations. Our characterizations take consumption data as primitives, and provide nonparametric revealed-preference tests. We apply our tests to data from two recent experiments and find that our axiomatization delivers new insights and perspectives on datasets that had been analyzed by traditional parametric methods.

摘要：We examine the relationship between job security and productivity in a fixed wage worker-firm relationship facing match quality uncertainty. The worker's action affects both learning and current productivity. The firm, seeing worker behavior and outcomes, makes a firing decision. As bad news accrues, the firm cannot commit to retain the worker. This creates perverse incentives: the worker strategically slows learning, harming productivity. We fully characterize the unique equilibrium in our co...

摘要：We investigate how distorted, yet structured, beliefs can persist in strategic situations. Specifically, we study two-player games in which each player is endowed with a biased-belief function that represents the discrepancy between a player's beliefs about the opponent's strategy and the actual strategy. Our equilibrium condition requires that (i) each player choose a best-response strategy to his distorted belief about the opponent's strategy, and (ii) the distortion functions form best resp...

摘要：The lack of hard evidence in allegations about sexual misconduct makes it difficult to separate true allegations from false ones. We provide a model in which victims and potential libelers face the same costs and benefits from making an allegation, but the tendency for perpetrators of sexual misconduct to engage in repeat offenses allows semiseparation to occur, which lends credibility to such allegations. Our model also explains why reports about sexual misconduct are often delayed, and why t...

摘要：This paper studies (1) whether, from a welfare point of view, oligopolistic competition leads to too few or too many products in a market, and (2) how a change in competition affects the number and the composition of product offerings. We address these two questions in the context of the US smartphone market. Our findings show that this market contains too few products and that a reduction in competition decreases both the number and variety of products. These results suggest that product choi...
