This paper addresses the purchasing power parity (PPP) puzzle for a commodity currency. In particular, we analyse the real exchange rate behaviour in Norway, which has a primary commodity (oil) that constitutes the majority of its exports. A substantial part of the literature on commodity...

this paper analyzes two effects which might have an important impact on a reduction of global external imbalances. These are valuation effects on the one hand and interest rate effects on the other hand. We use a four-region model that is based on the models by Obstfeld and Rogoff (2005) and...

Real exchange rates are quite persistent. Standard unit root tests are not very powerful in drawing a conclusion regarding the validity of purchasing power parity [PPP]. Rather than asking if PPP holds throughout the whole sample period, we examine if PPP holds sometimes by employing...

This paper analyzes deviations from uncovered interest rate parity which are interpreted as indicator of the substitutability of currencies. Backward recursive statistical tests and error correction models are applied to study the co-movement of interest rates, and rolling regressions are used...

This paper contributes to the debate about the puzzle of the Swiss Interest Rate Island. It starts out by establishing some stylized facts about the nature of the puzzle. First it shows that long run real returns on Swiss Euro Deposits have been significantly lower than in any other major...

This paper analyzes purchasing power parity and uncovered interest parity in the laboratory. It finds strong evidence that purchasing power parity, covered interest parity, and uncovered interest parity hold. Subjects are endowed with an intrinsically useless (green) currency that can be used to...

The variance of real interest rate differentials (rids) is decomposed between ex post deviations from relative purchasing power parity and uncovered interest rate parity (UIRP) for a set of emerging markets from 1995M5 to 2004M3. The results point out to
