摘要：We study theoretically and experimentally how the bracketing of non-binding goals in a repeated task affects the level of goals that people set for themselves, the actual effort provided, and the pattern of effort over time. In our model, a sophisticated or partially naive individual sets either daily or weekly goals to overcome a motivational problem caused by present-biased preferences. In an online, real-effort experiment, we randomly allocated subjects to treatments where they set either d...

摘要：This paper studies the policy implications of the endogeneity of information about the state of the economy. The business cycle can be made less noisy, and more efficient, by incentivizing firms to vary their pricing and production decisions more with their beliefs about the state of the economy. This calls for countercyclical taxes complemented by a monetary policy that leans against the wind. The optimal policies trade-off allocative efficiency for informational efficiency.

摘要：We examine a strong form of robust implementation in dynamic mechanisms that is both belief- and belief-revision-free. Specifically, we characterize robust wPBE-implementation, that is, full implementation in weak Perfect Bayesian equilibrium across all type spaces. We introduce a dynamic robust monotonicity condition that is weaker than Bergemann and Morris' (2011) robust monotonicity condition and show that under a conditional no total indifference condition, ex-post incentive compatibility ...

摘要：It is commonly understood that making a tournament ranking process more noisy leads to a reduction in effort exerted by players in the tournament. But what exactly does it mean to have more noise? We address this question and show that the level of risk, as measured by the variance or the second-order stochastic dominance order, is not the answer, in general. For rank-order tournaments with arbitrary prizes, equilibrium effort decreases as noise becomes more dispersed, in the sense of the disp...

摘要：A seller is selling multiple objects to a set of agents, who can buy at most one object. Each agent's preference over (object, payment) pairs need not be quasilinear. The seller considers the following desiderata for her mechanism, which she terms desirable: (1) strategy-proofness, (2) ex post individual rationality, (3) equal treatment of equals, (4) no wastage (every object is allocated to some agent). The minimum Walrasian equilibrium price (MWEP) mechanism is desirable. We show that at eac...

摘要：What does utility maximization subject to a budget constraint imply for intertemporal choice under uncertainty? Assuming consumers face a two period consumption-portfolio problem where asset markets are incomplete, we address this question following both the standard local infinitesimal and finite data approaches. To focus on the separate roles of time and risk preferences, individuals maximize KPS (Kreps- Porteus-Selden) preferences. The consumption-portfolio problem is decomposed into a one ...

摘要：Before embarking on a project, a principal must often rely on an agent to learn about its profitability. We model this learning as a two-armed bandit problem and highlight the interaction between learning (experimentation) and production. We derive the optimal contract for both experimentation and production when the agent has private information about the efficiency of experimentation. This private information in the experimentation stage generates asymmetric information in the production sta...

摘要：We introduce and characterize a recursive model of dynamic choice that accommodates naivete about present bias. While recursive representations are important for infinite-horizon problems, the commonly used Strotz model of time inconsistency presents well-known technical difficulties that preclude such representations. Our model incorporates costly self-control in the sense of Gul and Pesendorfer (2001) to overcome these hurdles. The important novel condition is an axiom for naivete. We first ...

摘要：We analyze cheap talk warnings about a strategic adversary, with applications to cybersecurity and national security. Each period an expert receives a noisy private signal about whether an attack by the adversary is feasible. The expert wants to warn a decision maker while also maintaining credibility for future warnings, but unlike in a standard cheap talk game, the adversary can undermine the expert's credibility by delaying attack. While such delays increase warning fatigue, they also make ...

摘要：This paper investigates endogenous network formation by heterogeneous agents. The agents' types determine the value of linking and we incorporate spillovers as utility from indirect connections. We provide sufficient conditions for a class of networks with sorting to be stable for low to moderate spillovers; with only two types these networks are the unique pairwise stable ones. We also show that this sorting is suboptimal for moderate to high spillovers despite otherwise obeying the condition...
