We study when equilibrium prices can aggregate information in an auction market with a large population of traders. Our main result identifies a property of information—the betweenness property that is both necessary and sufficient for information aggregation. The characterization provides...

We consider a large rational expectations economy built on Han and Yang (2013) where traders can share information with each other via an information network and investigate the impact of network connectedness on market equilibrium outcomes. We find that in the equilibrium with endogenous...

Rothschild and Stiglitz (1976) show that there need not exist a competitive equilibrium in markets with adverse selection. Building on their framework we demonstrate that externalities between agents - an agent's utility upon accepting a contract depends on the average type attracted by the...

The paper provides a framework for analysis of remuneration to agents whose task is to make well-informed decisions on behalf of a principal, with managers in large corporations as the most prominent example. The principal and agent initially bargain over the pay scheme to the latter. The...

This paper examines the effect of imperfect labor market competition on the efficiency of compensation schemes in a setting with moral hazard, private information and risk-averse agents. Two vertically differentiated firms compete for agents by offering contracts with fixed and variable...

This paper examines the effect of imperfect labor market competition on the efficiency of compensation schemes in a setting with moral hazard and risk-averse agents, who have private information on their productivity. Two vertically differentiated firms compete for agents by offering contracts...

We analyze competitive credit markets with asymmetric information in which borrowers seek financing for either positive or negative net present value projects. The striking result is that there always exists an equilibrium where investment is efficient, while competitive lenders make strictly...

This paper studies general markets with adverse selection in which symmetric firms supply (potentially multiple) products to privately-informed consumers and compete with price schedules. I show that a basic price cap regulation, in which the price caps are endogenously determined by firms,...
