An influential literature has documented large differences across countries and industries in terms of product quality. It is important to understand the determinants of these differences, because the production of high-quality goods influences key aspects of economic performance. In this paper,...

We study patterns of FDI in a multi-country world economy. First, we present evidence for a broad sample of countries that firms direct FDI disproportionately to markets with income levels similar to their home market. Then we develop a model featuring non-homothetic preferences for quality and...

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...

We study the relation between product quality and worker quality using an economic model that, under certain conditions, provides a direct link between product price, product quality and work-force quality. Our measures of product quality are the evolution in the detailed product price relative...

We analyse the impact of increased outside opportunities brought to consumers by access to a global market on local market performance under monopoly versus oligopoly. If consumers have to choose once where to shop we show that under all forms of organizing the local market, increased...

We develop a theoretical framework to study illicit drugs markets and we estimate it using data on purchases of crack cocaine. Buyers are searching for high-quality drugs, but they determine drugs' quality (i.e., their purity) only after consuming them. Hence, sellers can rip off first-time...

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...

This paper studies advertising in vertically differentiated product markets with positive consumption externalities. In markets with consumption externalities, the value of the product to the consumer depends on the purchasing decisions of other consumers. In such markets, we show that firms...

This paper studies the impact of income inequality on the level of innovative activity in a model where innovations result in quality improvements. The market for quality goods is characterized by a natural oligopoly with two types of consumers – rich and poor. In general, we find that for...

We investigate the link between real exchange rates and sectoral total factor productivity measures for countries in the Eurozone. Real exchange rate patterns closely accord with an amended Balassa-Samuelson interpretation, both in cross-section and time series. We construct a sticky price...
