The empirical literature is abundant with detrended cointegration, where cointegration relations are estimated with deterministic trend terms. The use of detrended cointegration will mask important time series properties, however, because trend and cointegration indicate both deterministic and...

The purchasing power parity (PPP) hypothesis has attracted a lot of attention from academics and policy-makers particularly, during the recent float. Most previous studies used data from the developed world. This study examines the validity of the PPP hypothesis using data during the recent...

When univariate methods are applied to real exchange rates, point estimates of autoregressive coefficients typically imply very slow rates of mean reversion. Rogoff (1996) discusses that the remarkable consensus of 3-5 year half-lives of purchasing power parity (PPP) deviations is found among...

This paper models the dynamics of the adjustment process of Indonesian purchasing power parity (PPP) relative to US, Japan and Singapore by employing a nonlinear framework, which is recently shown to be appropriate in the presence of transaction costs associated with international trade. Using...

Looking closely at the PPP argument, it states that the currencies purchasing power should not change when comparing the same basket goods across countries, and these goods should all be tradable. Hence, if PPP is valid at all, it should be captured by the relative price indices that best fits...

The important concept of purchasing power parity (PPP) has a number of practical implications. Our central objective is to examine the stationarity of Turkey’s real exchange rates to test for the empirical validity of PPP. Our results from conventional univariate unit root tests fail to...
