We characterize optimal redistributive taxation when individuals are heterogeneous in their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are endogenous. Average tax rates are increasing...

Incumbent firms, especially in high-tech industries, often contract and collaborate with small research units on single projects. A delicate resulting contracting decision thus is how to allocate control. This paper considers the incumbent's problem to design a research contract that specifies:...

The paper studies the optimal education policy of a budget-constrained utilitarian government. Households differ in their income and in the intellectual ability of their children; income is observed by the government, but ability is private information. Households can choose to use private...

This paper concerns optimal taxation and public goods in an economic federation with decentralized leadership, where one lower level government is the first mover also in the horizontal dimension. Under plausible assumptions, horizontal leadership reinforces the incentives created by...

When employers can incur losses from the labor relationship in a gift exchange game, they offer lower wages on average than in a no-loss relationship. Taking employers’ risk of losing money into account, employees exert more effort per wage unit.

In a bargaining setting with asymmetrically informed, inequity-averse parties, a fully efficient mechanism (i.e., the double auction) exists if and only if compassion is strong. Less compassionate parties do not trade in the double auction in the limit of strong envy.

This chapter summarizes the many aspects of public policy for health care. I first consider government policy affecting individual behaviors. Government intervention to change individual actions such as smoking and drinking is frequently justified on externality grounds. External costs of...

Economists seeking to improve the efficiency of health care delivery frequently emphasize two issues: the fragmented structure of physician practices and poorly designed physician incentives. This paper analyzes these issues from the perspective of organizational economics. We begin with a brief...

I develop a dynamic model of financing decisions and optimal debt maturity choice in which creditors face adverse selection and learn about the firm's quality from news. In equilibrium, shareholders may choose to postpone debt issuance to reduce adverse selection and improve the pricing of newly...
