This paper uses a case study approach to explore the effects of NAFTA and GATT membership on innovation and trade in the Mexican soaps, detergents and surfactants (SDS) industry. Several basic findings emerge. First, the most fundamental effect of NAFTA and the GATT on the SDS industry was to...

This paper presents a tractable formalization and an empirical investigation of the quality-complementarity hypothesis, the hypothesis that input quality and plant productivity are complementary in generating output quality. We embed this complementarity in a general-equilibrium trade model with...

Exchange risk hedging in a static (i.e. one-period) setting is extremely straightforward. The variance-minimizing hedge of a particular future cash flow involves a forward contract equal but opposite in sign to the exposure of the cash flow. The exposure is the regression coefficient of the cash...

This paper examines the extent to which the destination of exports matters for the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. We use exchange-rate movements as a source of variation in export destinations and find that exporting to richer...

The uniform pricing puzzle for vertically differentiated products states that a monopolist sells high and low quality products at the same price despite the fact that quality is perfectly observable and that there are no significant costs of adjusting prices. The puzzle is relevant for movies,...

We utilize a unique database from a large legal services provider to examine how service quality responds to the firm's available capacity and workload, and to the nature of the firm-client relationship. We develop empirical measures of both the (internal) level of resources available to the...

This paper examines how the distribution of prices and consumer welfare change with the number of competitors in a model where consumers di¤er in the amount of price information they have. We only assume that an increase in the number of competitors results in an increase in the probability...

When will a monopolist have incentives to foreclose a complementary market by degrading compatibility/interoperability of his products with those of rivals? We develop a framework where leveraging extracts more rents from the monopoly market by 'restoring' second degree price discrimination. In...

Ranking have become increasingly popular on markets for study programs, restaurants, wines, cars, etc. This paper analyses the welfare implication of such rankings. Consumers have to make a choice between two goods of unknown quality with exogenous presence or absence of an informative ranking....
