Foreign Exchange Market Efficiency : Fractional Cointegration Approach
Belkacem, Lotfi; El Meddeb, Zahra; Boubaker, Heni - 2005
In the present study, we investigate the market weak efficiency hypothesis (MEH) in the case of the Tunisian exchange market. For this aim, we use fractional cointegration tests based essentially on estimation of an error correction bivariate ARFIMA model. The cointegration tests are conducted...
