The authors analyze a continuous time model with a Walrasian labor market and a random search retail market with prices set on a take-it or leave-it basis. The equilibrium distribution of money holdings is the asymptotic steady state of this stochastic process. There is a unique uniform price...

This paper presents a new approach to organizing universal health insurance. First, the government divides the entire population into many large groups. Then, the government creates a federal health insurance system (HealthFed), modeled on the Federal Reserve System, to fill the role now played...

We characterize a generalization of discounted logistic choice that incorporates a parameter to capture different views the agent might have about the costs and benefits of larger choice sets. The discounted logit model used in the empirical literature is the special case that displays a...

The authors modify the standard principal-agent model with oral hazard by allowing the contract to be renegotiated after the agent's choice of action and before the observation of the action's consequences. In equilibrium, the agent randomizes over effort levels. The optimal contract gives the...

The authors study the steady states of a system in which players learn about the strategies their opponents are playing by updating their Bayesian priors in light of their observations. Players are matched.at random to play a fixed extensive-form game and each player observes the realized...
