Notre méthodologie empirique repose sur la spécification de Knetter (1993) : comme le taux de marge et le coût marginal ne peuvent être observés, cette spécification empirique permet de saisir, par un jeu complet de dummies temporelles, tous les mouvements communs aux prix des produits...

This paper analyzes the impact of increasing international competition on the evolution of export prices in the last three decades. We investigate both the sensitivity of export prices to exchange rate movements, and the dynamics of profit margins for a large number of manufacturing products...

This paper employs a weighted network approach to study the empirical properties of the web of trade relationships among world countries, and its evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large...

This paper employs a weighted network analysis to study the empirical properties of the world trade web and their evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large number of strong relationships, thus...

Over the past four decades the High Performing Asian Economies (HPAE) have followed a development strategy based on the exposure of their local markets to the presence of foreign competition and on an outward oriented production. In contrast, Latin American Economies (LATAM) began taking steps...

This paper presents a simple stochastic model of proportionate growth to describe international trade and it applies this set-up to the relationship between export dynamics and economic development. Trade flows are assumed to grow as a geometric Brownian motion while new trade links follow a...

This paper contributes to the literature explaining firm-level heterogeneity in the extensive margin of trade, defined as the number of products exported by each firm. We develop a dynamic model where firms must invest in R&D to maintain and increase their portfolio of goods: the process of...

The paper develops a simple model to describe the dynamics of international trade flows. We show that such a setup is able to simultaneously match a large number of empirical regularities, such as the fraction of zero trade flows across pairs of countries, the positive relationship between...
