Is the Exchange Rate of Bangladesh Mean Reverting? A Panel Unit Root Approach

Abstract

This paper evaluates whether the exchange rate of Bangladesh is mean reverting or not by applying first-generation and second-generation panel unit root test approaches. The paper considers annual data from 1986 to 2011 of major twenty-two trading partners of Bangladesh. Although some inconclusive outcomes emerge from the first-generation tests, the second-generation test reconciles the controversy and confirms that the weak form of PPP is relevant for Bangladesh. Consequently, the bilateral exchange rate of Bangladesh is mean reverting and the PPP hypothesis can be considered as an exchange rate determinant in the long-run.
