We propose a cross-country specialization index - the B ⋆ - defined as the share of a given product in total country’s exports “normalized” by the average share across all countries. This indicator draws from the Revealed Comparative Advantage index suggested by Balassa (Manch Sch Econ Soc Stud 33(2):99–123, 1965), but its dynamic and cardinal properties are more suitable to perform a cross-country...
This paper proposes an empirical framework for analyzing the dynamics of trade specialization, using a symmetric transformation of the standard Balassa (Manch Sch Econ Soc Stud 33(2):99–123, 1965) index and the conditional density estimation methods suggested by Hyndman et al. (J Comput Graph Stat 5(4):315–336, 1996). The framework is implemented using data on the cross-sector export and import specialization...
