The optimal income tax problem, since it requires self-selection constraints which define nonconvex feasible sets, is one of the many problems in economics for which randomization in the solution may be desirable. For a two-class economy. we characterize the optimal random tax schedules and we...

The optimal income taxation problem has been extensively studied in one-period models. This paper analyzes optimal income taxation when consumers work for many periods. We also analyze what information, if any, that the government learns about abilities in one period can be used in later periods...

Most analyses of optimal income taxation make restrictive technical assumptions on preferences (such as single-crossing) and only derive properties of welfare-maximizing tax schedules. Here, for an economy with any finite numbers of groups and commodities, Pareto efficient tax structures are...

This paper presents results from a 1971 natural experiment carried out by the Canadian government on the unemployment insurance system. At that time, they dramatically increased the generosity of the system. We find that the propensity to collect UI increases with a first time exposure to the...

This paper uses data from the 1990s to examine changes in the wages, employment, and effort of nurses in California hospitals following takeovers by large chains. The market for nurses has been described as a classic monopsony, so that one might expect increases in firm market power to be...

This chapter reviews the literature on employment and labor law. The goal of the review is to understand why every jurisdiction in the world has extensive employment law, particularly employment protection law, while most economic analysis of the law suggests that less employment protection...

Contract law and the economics of contract have, for the most part, developed independently of each other. In this essay, we briefly review the notion of a contract from the perspective of lawyer, and then use this framework to organize the economics literature on contract. The review thus...

Reforms to the Joint and Several Liability rule (JSL) are one of the most common tort reforms and have been implemented by most US states. JSL allows plaintiffs to claim full recovery from one of the defendants, even if that defendant is only partially responsible for the tort. We develop a...

This paper provides a theoretical and empirical analysis of the intrinsic preferences of state appellate court judges. We construct a panel data set using published decisions from state supreme court cases merged with institutional and biographical information on all (1,636) state supreme court...

Expert performance is often evaluated in a one dimensional way by assuming that good experts have good outcomes. We examine the example of expertise in medicine and develop a model that allows for two dimensions of physician performance: Procedural decision making and skill performing...
