Robustness of the proposed measures of revealed comparative advantage

The concept of revealed comparative advantage (RCA) stands as a major pillar in empirical trade literature. Yet there is no absolute preference among the suggested RCA measures. Given that these are volume-based indices, results of any relevant empirical analysis would be heavily influenced by the choice of the RCA measure. Considering such an ambiguity, this paper critically evaluates the proposed measures of RCA to identify the ideal measure based on theoretical, statistical and empirical precedence. Its suggested that the Balassa Index and the two corresponding multiplicative normalised variants are more consistent and robust for RCA analysis. -- Revealed Comparative Advantage
