this paper investigates the effect of exchange rate uncertainty on the iran’s import trade. the exchange rate ‎uncertainty series were generated utilizing the tarch model. this model analyzes the asymmetric effects. the analysis of uncertainty and asymmetry ‎of the exchange rate shows significant tarch ‎effect on iran’s exchange rates‎. the findings of the study indicate negative shocks (bad ne...

We investigate the link between real exchange rates and sectoral total factor productivity measures for countries in the Eurozone. Real exchange rate patterns closely accord with an amended Balassa-Samuelson interpretation, both in cross-section and time series. We construct a sticky price dynamic general equilibrium model to generate a crosssection and time series of real exchange rates that c...

This paper studies the response of the nominal exchange rate to monetary shocks in an economy with consumption home bias (CHB) and sticky wages. The importance of accounting for the exchange rate with CHB are twofold. CHB is a consequence of the small open economy assumption when outputs are specialized and fluctuations in the relative price of traded goods generate deviations from purchasing p...

Recent studies of purchasing power parity (PPP) account for the possible presence of unit roots in nominal exchange rates and relative price indices by applying standard unit-root tests to real exchange rates, which are ratios of nominal exchange rates and relative price indices. These studies occasionally find evidence of PPP, but as a whole, the evidence is not definitive. Standard unit-root ...
