This paper studies the role of new exporting entrepreneurs – defined as firms that became exporters – in determining export growth in a fast growing and export oriented middle-income country i.e., Costa Rica during 1997-2007. It provides a detailed description of the contribution of export entrepreneurs in the short and long run, and comparing the observed patterns with an emerging literature on the role of the “extensive” margin in international trade.
