Exporting firms often enter foreign markets that are similar to previous export destinations. We develop a dynamic model in which a firm's exports in a market may depend on how similar the market is to the firm's home country (gravity) and to its previous export destinations (extended gravity)....

We develop a structural gravity model that introduces scale effects in bilateral trade. Scale effects and incomplete passthrough give two channels through which exchange rates have real effects on trade patterns. Estimates from Canadian provincial trade data identify these effects through their...

We analyze a large dataset of commercial records produced by Assyrian merchants in the 19th Century BCE. Using the information collected from these records, we estimate a structural gravity model of long-distance trade in the Bronze Age. We use our structural gravity model to locate lost ancient...

Preferential liberalization of trade in services is a central feature of the new regionalism. "GATS-Plus" and "GATS-Minus" have become the distinctive characteristics of the service RTAs and this paper aims to investigate and distinguish the different effect of the "GATS-Plus" and "GATS-Minus"...

Gravity-based cross-sectional evidence indicates that currency unions stimulate trade; cross-sectional evidence indicates that trade stimulates output. This paper estimates the effect that currency union has, via trade, on output per capita. We use economic and geographic data for over 200...

A gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade. The panel data set used includes bilateral observations for five years spanning 1970 through 1990 for 186 countries. In this data set, there are over one hundred...

This study quantifies the impact of traditional and new age' provisions of preferential trading arrangements (PTAs) on merchandise trade and investment. It does so by estimating gravity models of bilateral trade and investment. It finds that recent and some past PTAs are not as benign as some...

The core subjects of trade theory are the pattern and volume of trade: which goods are traded by which countries, and how much of those goods are traded. The first part of the paper discusses evidence on comparative advantage, with an emphasis on carefully connecting theory models to data...

This paper estimates the effect of sovereign debt renegotiation on international trade. Sovereign default may be associated with a subsequent decline in international trade either because creditors want to deter default by debtors, or because trade finance dries up after default. To estimate the...
