Recent theoretical work on economic geography emphasizes the interplay of transport costs and plant-level increasing returns. In these models, the spatial distribution of demand is a key determinant of economic outcomes. In one strand, it is argued that higher demand gives rise to a more than...

Using data on name distributions in 95 French departments observed from 1946 to 2002, we investigate spatial and social mechanisms behind the transmission of parental preferences. Drawing inspiration from recent work on social interactions, we develop a simple discrete choice model that predicts...

Knickerbocker (1973) introduced ‘oligopolistic reaction’ to explain why firms follow rivals into foreign markets. We develop a model that incorporates central features of Knickerbocker's story-oligopoly, uncertainty, and risk aversion-to establish the conditions required to generate...

The majority of independent nations today were part of empires in 1945. Using bilateral trade data from 1948 to 2006, we examine the effect of independence on post-colonial trade. On average, there is little short run effect of trade with the colonizer (metropole). However, after three decades...

Quantifications of gains from trade in heterogeneous firm models assume that productivity is Pareto distributed. Replacing this assumption with log-normal heterogeneity retains some useful Pareto features, while providing a substantially better fit to sales distributions—especially in the left...

National borders, including the easily crossed US-Canada border, have been shown to separate markets and sustain price differences. The resulting arbitrage opportunities vary temporally with the exchange rate and cross-sectionally with travelers' distance to the border. We estimate a structural...

This chapter focuses on the estimation and interpretation of gravity equations for bilateral trade. This necessarily involves a careful consideration of the theoretical underpinnings since it has become clear that naive approaches to estimation lead to biased and frequently misinterpreted...

With increasing sophistication, economists have been estimating gravity equations for five decades. Robust evidence shows that borders and distance impede trade by much more than tariffs or transports costs can explain. We therefore advocate investigation of other sources of resistance, despite...

Investigations of the effect of quality differences on heterogeneous performance in exporting have been limited by lack of direct measures of quality. We examine exports of French wine, matching the exporting firms to producer ratings from two wine guides. We show that high quality producers...

Free trade in audio-visual services has faced opposition on the grounds that foreign media undermine domestic culture, and ultimately, global diversity. We assess the media-culture link using name frequencies as a measure of tastes. Using a 47-year panel of French birth registries, we first show...
