This paper examines Argentine exports at the firm level between 2003 and 2011, a period of exceptional and sustained export growth. While at the product level, the pattern of specialisation barely changed, exporters exhibit new dynamics in international markets: firms not only expanded sales abroad by increasing their exports in existing markets, but also by entering into new destinations and adding new products. That is, new export strategies allowed exporters achieve greater resistance to the variations in the macroeconomic environment. We find that the importance of the different export margins changes overtime: while the currency is depreciated, the intensive margin explains most of export growth, whereas the subextensive and extensive margins become the main source of export growth once the currency appreciates. We also uncover a strong complementarity between import and export growth.
