The purpose of this study is to investigate the validity of the absolute version of the purchasing power parity (PPP) of a sample of four advanced and four emerging countries covering the period from 1993 to 2014. To examine the existence of PPP we apply the Augmented Dickey-Fuller, DF-GLS and...

We sketch a model that shows how skill-biased technological change may reverse the classic Balassa-Samuelson effect, leading to a negative relationship between the productivity in the tradable sector and the real exchange rate. In a small open economy, export goods are produced with capital,...

While it is widely agreed that Purchasing Power Parity (PPP) holds as a long-run concept the specific dynamic driving the process is largely build upon a priori economic belief rather than a thorough statistical modeling procedure. The two prevailing time series models, i.e. the exponential...

Recent research has generated support to the notion that the real exchange rate adjustment is nonlinear and that the PPP half-life is faster than the puzzling 3 to 5 years based on linear models. While different nonlinear models survive the specification tests against linear ones, there is...

This paper addresses difficulties in modelling exchange rates in South Africa. Real exchange rate models of earlier research seem to be sensitive to the sample period considered, alternative variable definition, data frequency and estimation methods. Alternative exchange rate models proposed in...

It has been noted in many papers that primary commodity exporting economies and developing countries frequently respond to movements in the real exchange rate as part of their monetary policies. For many central banks, this variable is the primary indicator of real activity. At the same time,...

We set up and estimate a structural unobserved components open economy model for the rate of unemployment and the real exchange rate in Sweden. This approach enables us to simultaneously determine changes in both cyclical and equilibrium rates. Our results show that the Natural Rate/NAIRU has...

This study revisits the relation between the uncovered interest parity (UIP), the ex ante purchasing power parity (EXPPP) and the real interest parity (RIP) using a VAR approach for the US dollar, the British sterling and the Japanese yen interest rates, exchange rates and changes in prices. The...
