We analyze the empirical violation of the Hillman condition, a necessary and sufficient condition for the correspondence between comparative advantage and pre-trade relative prices. Our comprehensive data set allows us to investigate the Hillman condition for virtually all countries of the...

Resource-based theories of product diversification argue that firms grow by diversifying into products that share common capabilities. We bridge the product diversification literature and the innovation literature by documenting the positive correlation between a firm’s innovation-based...

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...

The concept of revealed comparative advantage (RCA) stands as a major pillar in empirical trade literature. Yet there is no absolute preference among the suggested RCA measures. Given that these are volume-based indices, results of any relevant empirical analysis would be heavily influenced by...

Latin American countries have lost competitiveness in world markets in comparison to China over the last two decades. The main purpose of this study is to examine the causes of this development. To this end an augmented Dornbusch-type Ricardianʺ model is estimated using panel data. The...

We introduce quality differentiation into a Ricardian model of international trade. We show that (1) quality differentiation allows industrialized countries to be active across the full board of products, complex and simple ones, while developing countries systematically specialize in simple...

We illustrate a new source of comparative advantage that is generated by countries' different ability to adjust to technological change. Our model introduces substitution of workers in codifiable (routine) tasks with more efficient machines, a process extensively documented in the labor...
