This study tests the importance of Ricardian technology differences for international trade. The empirical analysis has three comparative advantages: including emerging and advanced economies, isolating panel variation regarding the link between productivity and exports, and exploiting...

Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

The gravity model is a workhorse tool that has been widely used in international trade. However, one empirical question that frequently arises is related to the conceptualization and measurement of distance. To overcome this limitation, our study proposes an index of distance based on...

We use French microdata to test an ubiquitous property of firm-based models of importing. When firm efficiency is factor neutral and input prices and qualities are common across firms, firm size should have no effect on expenditure shares on the different products and varieties sourced, holding...

Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

To study the effects of tariffs on gross domestic product (GDP), one needs import demand elasticities at the tariff line level that are consistent with GDP maximization. These do not exist. Kee, Nicita, and Olarreaga modify Kohli's (1991) GDP function approach to estimate demand elasticities for...

The elasticity of substitution between domestic and imported goods is a central parameter in macroeconomic models, but after decades of empirical studies there is no consensus on its magnitude. Earlier literature using time series arrives at low values, while more recent studies using...

This paper provides estimates and explores the role of own price import demand (Armington) elasticities between different source countries for five agricultural commodities in a framework that incorporates temporal dimension formulated as trading habit persistence. The estimations employ FAO's...
