Financial vulnerability and export dynamics

International audienceThis study documents the implications of financial vulnerability for export diversification in developing economies. Financial crises, by increasing the incidence of sunk costs of entry into exporting, reduce firm export dynamics. Financially-vulnerable exporters are not able to fully realize economies of scale in production and access better-sophisticated technologies. The number of products and destinations per exporter are therefore likely to decrease in times of crisis. We use a comprehensive crosscountry dataset on export dynamics, with data covering 1997-2011 for 34 developing countries to investigate this issue. Building on the generalized difference-indifferences procedure proposed by Rajan & Zingales (1998) to remove any endogeneity bias, the results point to a negative and economically large effect of financial vulnerability on export diversification. Financial crises reduce export dynamics disproportionately more in financially dependent industries. This effect is less pronounced in countries with initially more open capital account, suggesting that portfolio inflows are good substitutes for underdeveloped domestic financial markets
