Revealed Comparative Advantage and the Alternatives as Measures of International Specialisation
The paper is an analysis of Balassa’s ‘revealed comparative advantage’ (RCA). The papers shows that when using the RCA, it should always be adjusted in such a way, so that it becomes symmetric.

The RSCA is also compared to other measures of international trade specialisation. These measures included the Michaely index and the chi square measure. The conclusion emerging from the analysis is that the RSCA is - on balance - the best measure of comparative
