Exporting and Productivity : Evidence for Egypt and Morocco

This paper investigates the link between exporting and importing activities and firm performance using a rich dataset on Egyptian and Moroccan firms. We test the export premium, self-selection and learning-by-exporting hypotheses using a number of firm characteristics. Our analysis also includes importing activities as a source of learning and considers their effects on productivity changes. A differences-in-differences matching estimator is used to address the endogeneity bias of target variables. The main results for Egyptian firms echo those reported for other countries using firm-level data, namely exporters are larger and more productive than non-exporters. In contrast, Moroccan exporters and non-exporters are strikingly similar. More specifically, no evidence is found of pre or post-entry differences in labour productivity for Moroccan firms
