"Shifting Armington trade preferences: A re-examination of the Mercosur–EU negotiations"
by Philippidis, George, Helena Resano and Ana Isabel Sanjuan Lopez

This paper examines the ‘small share’ problem inherent within the constant elasticity of substitution Armington specification. As a de facto research tool in the quantitative trade literature, this structural bias plagues the results of numerous multi-region CGE studies. Kuiper and van Tongeren (2006) proposed a fusion of gravity and CGE specifications to remedy said bias, which the current paper further develops. With a pervasiveness of ‘smallshare’ examples on Mercosur–European Union trade owing to the latter's restrictive tariff regime, the results reveal that significant additional trade led gains to Mercosur under a potential preferential trade agreement when compared with the standard Armington treatment.
