摘要:To study the constrained efficient public insurance provision against unemployment risks, we build a directed search model with households where a spouse's ability to provide consumption insurance determines the risks job-seekers take on. The planner's transfers to the unemployed fall with the spouse's income because of concave preferences with limited complementarity between consumption and the spouse's labor. Due to the absence of such a transfers scheme in the laissez-faire equilibrium, too...

摘要:We consider a Kyle (1985) one-period model where insider trading may be subject to a penalty that is increasing in trade size. We characterize the solution - the equilibrium price and optimal trading strategy explicitly and establish existence and uniqueness for an arbitrary penalty function for the case of uniformly distributed noise. We use this framework to capture the difference between legal and illegal insider trading, and identify the set of 'efficient penalty functions' that would be o...

摘要:This paper derives primitive, easily verifiable sufficient conditions for existence and uniqueness of (stochastic) recursive utilities for several important classes of preferences. In order to accommodate models commonly used in practice, we allow both the state space and per-period utilities to be unbounded. For many of the models we study, existence and uniqueness is established under a single, primitive thin tail condition on the distribution of growth in per-period utilities. We present se...

摘要:This study examines the effects of changes in an agent's preferences over income and effort on the principal's costs. The incentive cost is fundamentally affected by two factors: the income-effort marginal rate of substitution at the first-best wage, and the degree of absolute risk aversion around it. Thus, a resulting increase in the first-best wage has mixed effects because both factors are altered simultaneously. When the limited liability constraint does not bind and if the utility is conc...

摘要:This paper proposes a model of how biased individuals update beliefs in the presence of informational ambiguity. Individuals are ambiguous about the actual signal-generating process and interpret signals according to the model that can best support their biases. This paper provides a complete characterization of the limit beliefs under this rule. The presence of model ambiguity has the following effects. First, it destroys correct learning even if infinitely many informative signals can be obs...

摘要:The Gibbard-Satterthwaite theorem implies that all anonymous, Pareto-optimal, and single-valued social choice functions can be strategically manipulated. In this paper, we investigate whether there exist social choice correspondences (SCCs), that satisfy these conditions under various assumptions about how single alternatives are eventually selected from the choice set. These assumptions include even-chance lotteries as well as resolute choice functions and linear tie-breaking orderings unknow...

摘要:I estimate and evaluate a model with a representative agent who is concerned that the persistence properties of her baseline model of consumption and inflation are misspecified. Coping with model uncertainty, she discovers a pessimistically biased worst-case model that dictates her behavior. I combine interest rates and aggregate macro series with cross-equation restrictions implied by robust control theory to estimate this worst-case distribution and show that (1) the model's predictions abou...

摘要:We study trade in dynamic decentralized markets with adverse selection. In contrast to the literature on the topic so far, we assume that the informed sellers make the offers so that signaling through prices is possible. We establish basic properties of equilibria, discuss the standard two-type case in detail, and then analyze the general finite-type case. We prove that market efficiency, measured by the maximum gains from trade in equilibrium, is invariant to trading frictions. Our analysis s...

摘要:A seller chooses a reserve price in a second-price auction to maximize worst-case expected revenue when she knows only the mean of value distribution and an upper bound on either values themselves or variance. Values are private and iid. Using an indirect technique, we prove that it is always optimal to set the reserve price to the seller's own valuation. However, the maxmin reserve price may not be unique. Sometimes it is optimal to choose a deterministic reserve price even when randomization...

摘要:This paper models a two-way dynamic feedback mechanism between bank lending standards and firm entry. The composition of the borrower pool affects banks' screening decisions and the credit terms they offer. Likewise, lending standards affect potential entrepreneurs' decisions to start new firms, varying the borrower pool. Firms delay borrowing when they wait for banks to finish screening or when they expect the borrower pool to improve soon. The model's predictions are consistent with basic fa...
