This paper presents a trade model with capital and labor as factors of production. The main contribution of this paper is that it considers a new type of firm heterogeneity, which is empirically relevant: firms in this paper differ with respect to their factor shares in production. Therefore,...

This paper uses firm-level data for Mexican exporters to understand how firm-level export decisions shape a country's aggregate exports. The data allows for a characterization of both the crosssectional distribution of Mexican exports, across destinations and across exporting firms, and of the...

Based on a many-industry Chamberlinian-Ricardian trade model with iceberg trade costs, this note examines the impact of two modes of economic integration: a reduction in trade costs, and technical standardization due to information spillover. It is shown that these two modes of economic...

Small and medium-sized enterprises (SMEs) play an important role in generating economic activity and employment in developing and developed countries. However, partly due to remaining at-the-border trade costs, SMEs continue to be less represented in international trade – as direct exporters...
