Do regional trade agreements really boost trade? Evidence from agricultural products

We evaluate the impact on trade of regional trade agreements (RTAs) using a panel data approach at the detailed product level which exploits exports to third destinations and imports from third origins as benchmarks. This method is robust to both endogeneity and heterogeneity across agreements and across products, and allows differentiation between the impacts of tariff provisions and non-tariff provisions. The analysis covers agricultural and food products for 74 country pairs linked by an agreement entered into force during the period 1998-2009. Our estimate of the mean elasticity of substitution across imports at product level is slightly below four. Counterfactual simulations suggest that RTAs have increased partners' bilateral agricultural and food exports by 30-40 % on average, with marked heterogeneity across agreements. Also, RTAs are found to increase the probability of exporting a given product to a partner country although this impact is small. Finally, we found non-tariff provisions have no measurable trade impact.
