Edlund and Korn [2002] (EK) proposed that prostitutes are well paid and that the wage premium reflects foregone marriage market opportunities. However, studies of street prostitution in the U.S. have revealed only modest wages and considerable risks of disease and violence, casting doubt on...

Dani Rodrik (2008) offers a provocative argument for policies that seek to maintain an "undervalued" exchange rate in order to promote economic growth. The key to his argument is the empirical evidence that he presents, indicating correlation of his measure of undervaluation with economic growth...

I present a generalization of the standard (full-information) model of state- dependent pricing in which decisions about when to review a firm's existing price must be made on the basis of imprecise awareness of current market con- ditions. The imperfect information is endogenized using a...

Peter DeMarzo, Ilan Kremer and Andrzej Skrzypacz (2005, henceforth DKS) analyzed auctions in which bidders compete in securities. They show that a steeper security leads to a higher expected revenue for the seller, and also use this to establish the revenue ranking between standard auctions. In...

Street vice (anonymous prostitution, gambling, and the sale of illicit drugs) is spatially concentrated, confined largely to black neighborhoods in central cities, even though demand is quite evenly distributed throughout the general population. We show how this pattern can arise through the...

This is a formal analysis of how homeless shelters should operate: in particular, what quality of accommodations they should provide and how they should help their residents in securing conventional housing. I also examine timing. The results extend to cover optimal police response to street...

This paper takes the new approach of using a copula to characterize consumer preferences in a discrete choice model of product differentiation, and applies it to the economics of monopoly and duopoly. The comparative statics of demand strength and preference diversity, both properties of the...

The charging of school user fees is a much-debated policy issue in developing countries. In this paper, I evaluate the impact of a South African fee elimination program that was targeted at the poorest two quintiles of schools based on a community poverty score. Fixed effects estimates find that...

We consider the desirability of modifying a standard Taylor rule for a cen- tral bank's interest-rate policy to incorporate either an adjustment for changes in interest-rate spreads (as proposed by Taylor, 2008, and by McCulley and Toloui, 2008) or a response to variations in the aggregate...

Motivated by high and rising sex ratios in countries such as India and China, we formulate a theoretical framework for analyzing the impact of economic development on parental sex choice when sons are culturally prized and children provide old age support. Two key assumptions drive our model....
