We study the effect of economic openness on domestic prices by linking the quantity theory of money (QTM) with purchasing power parity (PPP). Our model pertains to long run domestic price movements, and shows that economic openness has a negative relation with QTM and a positive relation with...

Real exchange rate variance decompositions indicate that only a small fraction of real exchange rate movements can be attributed to changes in the relative price between traded and non-traded goods. This paper argues that those exercises, by ignoring the nature of the shocks behind real exchange...

We find that observed cross-country price differences primarily reflect regional market segmentation occurring within countries. Using a model of price-setting subject to costly search, we show that identification of national versus regional segmentation requires augmenting price data with...

While the impact of exchange rate changes on economic growth has long been an issue of key importance in international macroeconomics, it has received renewed attention in recent years, owing to weaker growth rates and the debate on "currency wars". However, in spite of its prevalence in the...

This paper uses fractional integration and cointegration in order to model the DM/dollar and the yen/dollar real exchange rates in terms of both monetary and real factors, more specifically real interest rate and labour productivity differentials. We find that whilst the individual series may be...

This paper studies the survival of fixed exchange rate regimes. The probability of an exit from a fixed exchange rate regime depends on the time spent within this regime. In such a context durations models are appropriate, in particular because of the possible non-monotonic pattern of duration...

We introduce a portfolio friction in a two-country DSGE model where investors face a constant probability to make new portfolio decisions. The friction leads to a more gradual portfolio adjustment to shocks and a weaker portfolio response to changes in expected excess returns. We apply the model...

The topic of contagion has gained importance in the last few decades, earning its place amongst the most debated topics in international economics. Contagion is a phenomenon where market disturbances in crisis times are observed to spread from one country to the other in the form of comovements...
