Federal student aid is designed to lower the costs of postsecondary attendance, working to ensure that higher education is widely accessible. The effectiveness of these programs depends crucially on the existence of offsetting price changes. Contrary to the intention of policymakers, I find that...

On the one hand, empiricists debate on which and how many labor dimensions are relevant for understanding the employment effects of the 1990's service offshoring boom. On the other hand, theorists pursue trade theory's traditional goal: to explain wage-responses to the shock. This paper...

This paper seeks to understand the returns to self-employment. The analysis is motivated by the empirical puzzle that most entrepreneurs enter and persist in self-employment, despite lower initial earnings and earnings growth (Hamilton, 2000). I propose a new hypothesis to make sense of this...

The asymptotic behavior of nonparametric estimators of the probability density function of an i.i.d. sample and of the spectral density function of a stationary time series have been studied in some detail in the last 50-60 years. Nevertheless, an open problem remains to date, namely the...

We study the asymptotic properties of a class of statistics used for testing the null hypothesis that an ordinal dominance curve is concave. The statistics are based on the Lp-distance between the empirical ordinal dominance curve and its least concave majo- rant, with 1 ≤ p ≤...

Almost all fisher models assume time-invariant parameter values of the underlying biological growth function except for an i.i.d. error term. We examine the economic implications of cyclical growth parameters in both single and multi-species models, which are frequently observed in many...

Consideration sets have become a central concept in the study of consumer behavior. Frequently, consumers are asked to split choice alternatives into those that that they would consider and those that they would not. Information on alternatives not in the consideration set is then typically not...

This paper identifies two distinct types of payoff kinks that can be exhibited by preference functions over monetary lotteries - "locally separable" vs. "locally nonseparable" - and illustrates their relationship to the payoff and probability derivatives of such functions. Expected utility and...

A major environmental tragedy of modern times is the widespread arsenic contamination of shallow drinking water wells in Bangladesh. High levels of arsenic present in many wells went unrecognized for years. Now large numbers of people show a range of symptoms associated with chronic arsenic...
