Policy makers in "small" countries facing trade liberalisation have become concerned with the potential loss of manufacturing employment and output to "large" economies in the presence of economies of scale in production and international transport costs. This paper offers a methodology to...

Using a gravity-type explanation of international trade flows at the industry level, it is shown that the pattern of comparative advantage in terms of sectoral export/import ratios in bilateral trade can be explained by relative income and relative per capita income. Total income of a country is...

This paper claims that distance alone is a poor proxy for international transport costs in gravity equations. We develop a theoretical framework with a manufacturing and a transport sector, where the level of manufacturing exports determines the demand for transport. Above a certain threshold,...

We derive a theory-based gravity-type equation that determines the main drivers of international technology diffusion under perfect enforcement of intellectual property rights. We estimate the gravity equation using bilateral royalty payments data for a sample of 53 countries and the period...

This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

Recent work suggests the patterns of international trade may be distorted because of information frictions. Little is known, however, about how advancements in information communication technology (ICT) affect trade patterns. The goal of our paper is to analyze how and why the adoption of such...

We propose and apply a new theory-consistent algorithm, which uses disaggregated inter-city trade data to identify a pyramidic city system with central places and associated hinterlands. Because central places possess more industries than the cities in their hinterlands, and because industries,...
