【摘要】In this paper I use a firm heterogeneity framework to relate product differentiation to export success. Relative demand in differentiated (low-σ) industries is less sensitive to price differences than in homogeneous (high-σ) industries. This demand mechanism implies positive relationship between product differentiation and plant level export probability as well as industry level share of exporters. I use the Rauch (1999) classification of goods, Broda and Weinstein (2006) elasticity estimates, and the elasticity of substitution estimated from 4-digit ISIC trade data to proxy for product differentiation. Employing Colombian plant level data I show that plants in low-σ industries are more likely to export as predicted by the model. Further, I do not find evidence that low-σ industries have a higher share of exporters. Identification comes from cross-industry variation in product differentiation.
