Although there is a consensus about time variation in market betas, it is not clear how this variation should be captured. Several researchers continue to analyze different versions of the conditional CAPM. However, Ghysels (1998) shows that these conditional CAPM models fail to capture the...

We analyze the post-float real exchange rates for a group of OECD countries using the newly developed threshold test and tests for unit roots against stationary but nonlinear alternative by Caner and Hansen ( 2001). These tools help us disentangle the nonlinearity from the nonstationarity...

This is a corrigendum. We correct the mistakes in Basci and Caner, "Are Real Exchange Rates Nonlinear or Non-stationary? Evidence from a New Threshold Unit Root Test" 2005, vol.9.4, Article 2.
