The aim of this paper is to provide a tractable model where both socialization (or network formation) and productive efforts can be analyzed simultaneously. This permits a full-fledged equilibrium/welfare analysis of network formation with endogenous productive efforts and heterogeneous agents....

This paper studies many-to-one matching markets where each student is assigned to a hospital. Each hospital has possibly multiple positions and responsive preferences. We study the game induced by the student-optimal stable matching mechanism. We assume that students play their weakly dominant...

We show that the welfare of a representative consumer can be related to observable aggregate data. To a first order, the change in welfare is summarized by (the present value of) the Solow productivity residual and by the growth rate of the capital stock per capita. We also show that...

This paper develops a methodology to estimate the entire population distributions from bin-aggregated sample data. We do this through the estimation of the parameters of mixtures of distributions that allow for maximal parametric flexibility. The statistical approach we develop enables...

We study the effect of borrowing limits on welfare in several versions of exchange and production economies. There is a "quantity" effect of a larger borrowing limit which is beneficial for liquidity constrained agents, but essentially irrelevant otherwise. There is also a "price effect" which...

Firms select not only how many, but also which workers to hire. Yet, in standard labor market models, all workers have the same probability of being hired. We argue that selective hiring crucially affects welfare analysis. Our model is isomorphic to a standard search and matching model under...

We study the interaction between insurance and capital markets within a single but general framework. We show that capital markets greatly enhance the risk sharing capacity of insurance markets and the scope of risks that are insurable because efficiency does not depend on the number of agents...
