Drivers of the duration of comparative advantage in the European Union’s agri-food exports by Imre FERTŐ and Stefan Bojnec was published in Agricultural Economics – Zemeldska Ekonomika
The article investigates the duration of comparative advantage indices in the European Union (EU-27) agri-food exports using the normalised revealed comparative advantage index on the global market. There is employed both a descriptive analysis of the duration of comparative advantage, and examined the major drivers using discrete-time duration models with proper controls for unobserved heterogeneity. The robustness of the models is tested with alternative estimation
procedures and sub-samples. Estimations show that the comparative advantages for most agri-food products survived for a certain number of years, but a high percentage of them have a shorter duration. Larger trade costs decrease the probability of survival in comparative advantages, while the level of economic development, the size of the country, the agri-food export diversification, and being a new EU member state increases it. Implications for the EU-27 member states and agri-
-food policies are suggested in the conclusion.
