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...

We study a health-insurance market where individuals are offered coverage against both medical expenditures and losses in income. Individuals vary in their level of innate ability. If there is private information about the probability of illness and an individual’s innate ability is...

This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

We analyze a long-term contracting problem involving common uncertainty about a parameter capturing the productivity of the relationship, and featuring a hidden action for the agent. We develop an approach that works for any utility function when the parameter and noise are normally distributed...

We consider resource allocation within an organisation and show how delegation bears on moral hazard and adverse selection when agents have a preference for autonomy. Agents may care about autonomy for reasons of job-satisfaction, status or greater reputation when performing well under autonomy....

We develop a private-information model of union contract negotiations in which disputes signal a firm's willingness to pay. Previous models have assumed that all labor disputes take the form of a strike. Yet a prominent feature of U.S. collective bargaining is the holdout: negotiations often...

The resolution of any bargaining conflict depends crucially on the relative urgency of the agents to reach agreement and the information each agent has about the others' preferences. This paper explores, within the context of an infinite-horizon bargaining model with two-sided uncertainty, how...

The role of strategic delay is analyzed in an infinite-horizon alternating-offer model of bargaining. A buyer and seller are engaged in the trade of a single object. Both bargainers have private information about their own preferences and are impatient in that delaying agreement is costly. An...

A central question in economics is understanding the difficulties that parties have in reaching mutually beneficial agreements. Informational differences provide an appealing explanation for bargaining inefficiencies. This chapter provides an overview of the theoretical and empirical literature...
