Heterogeneous Popularity and Exporting Uncertainty

Empirical work shows that a considerable fraction of firms quit the export market soon after entrance. A natural interpretation to this quick exit from the export market is that firms did not predict the profitability of their variety correctly before entry. In this paper a firm heterogeneity model is put forward to account for this type of exporting uncertainty due to lack of information. Firms are heterogeneous with respect to the popularity of their good, technically the CES weight, and the popularity of a good varies across markets. Therefore, firms are uncertain about the profitability of their good in the export market. Upon payment of sunk export costs the popularity of the good is revealed and some firms stay in the export market while others leave. Comparative statics show that lower sunk export costs lead to higher probability that firms start to export, but to lower probability of export success. Lower fixed export costs instead lead to both a higher probability to start exporting and to be successful in exporting.
