We investigate and compare countries' export growth based on their performance at the extensive and intensive export margins. Our empirical approach is motivated by an extension to the Melitz (2003) model of heterogeneous firms in which exporters are subject to a one-time sunk cost and also a...

This paper employs survival analysis to study the duration of US imports. We find that the median duration of exporting a product to the US is very short, on the order to two to four years. Our results also indicate that there is negative duration dependence meaning that if a country is able to...

We examine the extent to which product differentiation affects duration of US import trade relationships. The results are consistent with a matching model of trade formation. Using highly disaggregated product level data we estimate the hazard rate is at least 23% higher for homogeneous goods...
