"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...

"Feenstra and Kee study the link between export product variety and country productivity based on data from 34 industrial and developing countries, from 1982 to 1997. They measure export product variety by the share of U.S. imports on the set of goods exported by each sampled country relative to...

Country size matters in determining the effectiveness of domestic and foreign competition on pricing behavior in manufacturing. Removing barriers to entry of new firms reduces markups more in large countries, while removing barriers to imports reduces markups more in small countries

This paper provides a consistent estimate of the bound of the marginal effect of an unobserved right-hand side variable on the dependent variable when only the sum of that variable with a positively correlated variable is available

In the classic literature of multi-sector small open economy, there are two, competing hypotheses on growth. Findlay and Grubert (1959) showed that productivity growth in one sector affects the factor intensity of all sectors. Rybczynski (1955) presents the long run growth effects of endowment...

This paper provides a systematic estimation of import demand elasticities for a broad group of countries at a very disaggregated level of product detail. We use a semiflexible translog GDP function approach to formally derive import demands and their elasticities, which are estimated with data...

Studies of the impact of trade restrictiveness on growth, poverty, or unemployment are frequent in the academic literature. Few authors, however, provide a precise definition of what they mean by trade restrictiveness. When they do, the definition is unlikely to have tight links with trade...

This paper quantifies trade policy changes and the associated trade impacts for about 100 countries between 2008 and 2009. Results show that there has been no widespread increase in protectionism. Only a few countries, including Russia, Argentina, Turkey, and China, have increased tariffs on...
