Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

How strong are strategic complementarities in price setting across firms? In this paper, we provide a direct empirical estimate of firm price responses to changes in prices of their competitors. We develop a general framework and an empirical identification strategy to estimate the elasticities...

In markets where spatial competition is important, many models predict that average prices are lower in denser markets (i.e., those with more producers per unit area). Homogeneous-producer models attribute this effect solely to lower optimal markups. However, when producers instead differ in...

The introduction of Tagamet in the United States in 1977 represented both a revolution in ulcer therapy and the beginning of an important new industry. Today there are four prescription H2- antagonist drugs: Tagamet, Zantac, Pepcid and Axid, and they comprise a multi-billion dollar market for...

We study firms' responses to minimum standards and other forms of regulatory intervention on both the probability of exit and the distribution of observable product quality, using firm level data for a nationally representative sample of markets. Our empirical work is motivated by the literature...

We estimate the degree of 'stickiness' in aggregate consumption growth (sometimes interpreted as reflecting consumption habits) for thirteen advanced economies. We find that, after controlling for measurement error, consumption growth has a high degree of autocorrelation, with a stickiness...

Existing literature assessing the impacts of transfers on low income households assumes that transfer program participants benefit by the full amount of cash transfers received. We argue that because tax-back arrangements accompany such transfer programmes, and endogenous participantion...

Recent work on the economic effects of minimum wages has stressed that the standard economic model, where increases in minimum wages depress employment, is not supported by the empirical findings in some labour markets. In this paper we present a theoretical framework which is general enough to...
