We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When...

We use consumer price data for 205 cities/regions in 21 countries to study PPP deviations before, during and after the major currency crises of the 1990s. We combine data from industrialized nations in North America (Unites States, Canada and Mexico), Europe (Germany, Italy, Spain and Portugal),...

Firstly, we show that domestic prices of net importer countries incorporate a risk premium, driven by higher moments of future nominal exchange rate returns and secondly, using US dollar exchange rates against three currencies of major net exporting countries to the US such as Canada, Japan and...

The goal of this empirical project is to test the validity of three economic models - The General Monetary, The Purchasing Power Parity and The Interest Rate Parity models in Turkey - basing on quarterly data for the period 1975 - 1999. The project takes into account the serious economic shocks...

This paper presents a simple model of how a small open economy can undervalue its real exchange rate using its capital account policies. The paper presents several properties of such policies, and proposes a rule of thumb to assess their welfare cost. The model is applied to an analysis of...

Asset price data imply a large degree of international risk sharing, while aggregate consumption data do not. We evaluate whether a model with trade in goods and endogenously segmented asset markets accounts for this puzzling discrepancy. Active households pay a fixed cost to transfer income...
