Do tariffs inhibit trade flows by limiting the entry of exporting firms (`extensive margin') or by restricting the average volume exported by each firm (`intensive margin')? Using a gravity equation approach, we analyze how the decrease in tariffs promoted during the 1990s by the Uruguay Round...

The paper investigates the dynamics of export relationships � defined as shipments by a given firm to a given destination in a given year � in a panel of almost 25,000 French exporters over the five-year period 1995-1999. It describes how the relationships evolve over time, presenting...

How are the dynamics of foreign and domestic sales correlated at the firm level? The question is relevant in that the sign of the correlation shapes the international transmission of shocks and the effects of policy measures. From a theoretical perspective, the correlation could be either zero,...

This paper examines the product specialisation of Italian exports over the period 1985-2001 to identify the roots of Italy�s sluggish export performance with respect to world trade in the second half of the 1990s. In particular, the analysis focuses on the role of product specialisation in...

This paper compares main European countries and the euro area specialization patterns. The analysis, that covers the period 1988-1997 and is based on a detailed sectoral breakdown, provides evidence to assess the degree of structural differences and convergence among European countries, which...

This paper compares the evolution of trade specialisation, by technological content, of Emilia-Romagna, Lombardia, Marche, Veneto and the Italian average over 1992-2002. It is shown that, over the period, the four regions� export performance has been negatively affected by the stationarity...

We analyze the foundations of the relationship between trade and total factor productivity (TFP) in the Ricardian model. Under general assumptions about the autarky distributions of industry productivities, trade openness raises TFP. This is due to the selection effect of international...
