This paper examines empirical strategies that have been or could be used to evaluate the importance of agglomeration and trade models. This theoretical approach, widely known as ‘New Economic Geography’ (NEG), emphasizes the interaction between transport costs and firm-level scale economies...

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...

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...

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...

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...

We investigate the hypothesis that firms prefer to locate ``where the markets are." We use a theoretical model of location choice under imperfect competition to formalise this concept. The model yields an equilibrium profit equation incorporating a term closely connected to the market potential...

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...

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...

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...
