Multinational firms play a pivotal role in the global economy, yet economic and finance research has largely examined them in isolation. Economic theory focuses on trade and multinational activity but gives relatively little attention to cross-border mergers, while finance research emphasizes...

We develop and test a theory of efficient international trade. Efficiency gains arise through lower trade costs faced by 'trade specialists', whose superiority over 'common traders' manifests itself through lower trade costs. To test our theory, we construct and deploy a novel dataset based on...

A striking pattern in transaction-level data is the concentration of international shipments in the hands of a few large firms. One common feature of dominating high-performance firms is that they produce multiple products and ship them to many destinations. Motivated by the emergence of highly...

We carry out an indirect inference test of two versions of a computable general equilibrium (CGE) model of world trade. One of these, the ‘classical’ model,is well-known as the Heckscher-Ohlin-Samuelson model of world trade, in which countries trade homogeneous products in world markets and...

Helpman, Melitz and Rubinstein (2008) derive gravity equations to estimate effects of trade barriers on the intensive and extensive margins of trade. They exploit the frequency of zeros in aggregate bilateral trade data to identify effects on the extensive margin and to obtain controls for firm...

What has been the overall global welfare impact of the accession to the World Trade Organization of a large country like China, or the global welfare impact of the completion of the Uruguay round of GATT negotiations? Can we come up with a simple user-friendly formula to calculate the global...

Growing empirical literature shows that financial constraints are reduce the chance of exporting, suggesting that financial constraints are an important determinant of international trade patterns. In this aspect, I develop a model of international trade based on new trade theory with financial...

Using a gravity model, this article presents an analysis of aggregate trade flows aimed at identifying China's impact on Latin America's trade. The results obtained indicate that: i) China´s growth in the last years implied a growing supply of exports to this market from most countries in the...
