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.

Standard unit root tests are not very powerful in drawing conclusions regarding the validity of Purchasing Power Parity (PPP). Rather than asking whether PPP holds throughout the whole sample period, we examine, in this study, if PPP holds sometimes by employing Hamilton-type (1989) Markov...

Recent empirical findings show that post-war real interest rates are quite persistent and that they also contain a large number of structural changes in their means. In this study, we also find concurring results for real interest rates from thirteen industrialized countries. We show, however,...

In this study, I provide corrections to the estimation results reported by Balassa (1963) on testing the implications of the Ricardian model of international trade. While all of his estimation results have changed, his main conclusions still pertain. I conjecture that the errors are most likely...

In this study, we show that a very simple structural break process can be easily confused with an Exponential Smooth Transition Autoregressive (ESTAR) model. Nonlinear estimates of an ESTAR model also appear to be quite significant and plausible when the model is applied to a structural break...
