Globalization has reinforced interdependency between international trade and mobility of the means of production. In this context, the questing of the impact of migration on trade, and especially on exports is valid. Up to now, migration’s positive effects on trade have been highlighted on a macroeconomic level. However current studies (both theoretical and empirical) have not much addressed the effects of migration on exports. Studies so far show that exports have an entry cost, namely to gain knowledge on the new market or to establish a local distribution/retail center. Thus the most “used” destinations are probably those with a small entry cost. We will also see the extent to which migrants employed by a French company can drive up company performance, in terms of sales volume or market penetration for their country of birth.
