This paper shows that Cournot competition in segmented markets generate both intra-industry trade and the gravity equation. The paper also demonstrates that the gravity equation holds if and only if the market shares of an exporting country do not depend on the market where it sells. Thus, the...

It has become common to measure the quality of exports using their unit export value (UEV). Applications of this method include studies of intra-industry trade (IIT) and analyses of industrial "competitiveness". This literature seems to assume that export quality and export price (the most...

International competitiveness is often regarded as crucial for the attainment of gains from trade, which may lead policy makers to subsidize exports. This view is based on confusion between the concepts of competitive and comparative advantage. The paper argues that when comparative advantage is...

I propose a method of moments estimator of revealed comparative advantage based on a flexible specification of trade flows that is consistent with a large class of gravity models of international trade. I show that this estimator has many desirable properties. It is theoretically consistent with...

Ricardian theories of production often take the comparative advantage of locations in diff erent industries to be uncorrelated. They are seen as the outcome of the realization of a random extreme value distribution. These theories do not take a stance regarding the counterfactual or implied...

This note points out that the treatment by many texts of export subsidies in a competitive market contains an error. The error is shown to be present in both partial equilibrium and general equilibrium models. The paper also considers the ranking of export subsidies, production subsidies and a...
