Econometric analyses of treatment response commonly use instrumental variable (IV) assumptions to identify treatment effects. Yet the credibility of IV assumptions is often a matter of considerable disagreement. There is therefore good reason to consider weaker but more credible assumptions. To...

Under the new welfare system, states must design and institute programs that both provide assistance and encourage work, two objectives that have thus far appeared incompatible. Will states meet these new requirements? For many innovative programs, the randomized welfare-to-work experiments...

The observation that many workers report wanting to work more or fewer hours at their current rate of pay appears to contradict standard neoclassical theory. Although most jobs limit the ability of workers to choose hours, economists typically assume that workers can choose hours by choosing...

We revisit the fundamental issue of market provision of variety associated with Chamberlin, Spence, and Dixit and Stiglitz when firms sell several products. Both products and firms are envisaged as di?erentiated. We propose a nested demand model where consumers decide upon a firm then which...

Technological changes over the past two decades have made it easier to distribute and to copy intellectual property. Creators and owners of intellectual property have responded to these changes with a variety of creative pricing strategies. The paper reviews some of these pricing innovations....

This paper estimates the dollar amount of public higher education subsidies received by U.S. youth and examines the distribution of subsidies and the taxes which finance them across parental and student income levels. Although youths from highincome families obtain more benefit from higher...

This paper reports laboratory data for a series of two-person games that are played only once. These games span the standard categories: static and dynamic games with complete and incomplete information. For each game, the treasure is a treatment for which behavior conforms quite nicely to the...

On college campuses across the country and on millions of home computers, too, young adults download from each other digital files containing recorded music and films for their entertainment. The owners of that copyrighted material pursue the downloaders with legal action as well as the software...

Recent theoretical advances have dramatically increased the relevance of game theory for predicting human behavior in interactive situation. By relaxing the assumptions of perfect rationality and perfect foresight, we obtain much improved explanations of (i) initial decisions (ii)dynamic...
