  1. P is the set of all products (with i∈P),
  2. XAi is the country A’s exports of product i,
  3. Xwi is the worlds’s exports of product i,
  4. Σj∈PXAj is the country A’s total exports (of all products j in P), and.
  5. Σj∈PXwj is the world’s total exports (of all products j in P).

What is revealed symmetric comparative advantage?

It shows that when using RCA, it should be adjusted such that it becomes symmetric around its neutral value. The proposed adjusted index is called ‘revealed symmetric comparative advantage’ (RSCA). The result of the analysis is that RSCA-on balance-is the best measure of comparative advantage.

Do you export when you have a comparative advantage?

Due to its multiplicative specification, it has a moving mean without a useful interpretation, while its distribution depends on the number of countries and industries.
