We advance a two-stage theoretical model which contends that the export performance of emerging economy firms (EEFs) will depend both upon their firm-specific capabilities and their home institutional environments. Specifically, we argue that EEFs will be more likely to export when facing more uncertainty at home from greater political instability, substantial informal competition, and high corruption. Furthermore, we hypothesize that firms’ export intensities will be contingent upon specialized internal capabilities such as a skilled workforce, top managerial experience, and access to external technologies. We test these hypotheses using a dataset of more than 16,000 firms from the four BRIC economies (i.e., Brazil, Russia, China and India). Our results confirm that political instability and informal competition have robust effects on the export propensity of EEFs, whilst export intensity is contingent upon the availability of skilled workers and access to external technologies via licensing.
