Exporter Heterogeneity and Price Discrimination: A Quantitative View

We quantify a class of commonly-employed general equilibrium models of international trade and pricing-to-market that feature firm-level heterogeneity and consumers with nonhomothetic preferences. We demonstrate theoretically that the models lack the flexibility to match salient features of US firm
