Ins, outs, and the duration of trade

Abstract

Abstract. We employ survival analysis to study the duration of U.S. imports. Our findings indicate international trade is far more dynamic than previously thought. The median duration of exporting a product to the U.S. is very short, on the order of two to four years. There is negative duration dependence. If a country is able to survive in the exporting market for the first few years it will face a very small probability of failure and will likely export the product for a long period of time. The results hold across countries and industries and are robust to aggregation. JEL classification: F14, F19, C14, C41
