We offer a critique of the popular notion that the log-change of the real exchange rate equals the log-difference between the IMRSs of economically distinct agents in two economies. Contrary to existing claims, we show that this interpretation does not hold true in reduced-form SDF models that...

We examine the impact of monetary injections in the Grossman-Weiss-Rotemberg Model and show that monetary shocks can lead to nominal exchange rates that are more volatile than inflation, money growth or interest rate differentials. Moreover, movements in real exchange rates following monetary...

Fixed exchange rates are less volatile than floating rates. But the volatility of macroeconomic variables such as money and output does not change very much across exchange rate regimes. This suggests that exchange rate models based only on macroeconomic fundamentals are unlikely to be very...

Empirical evidence shows that macroeconomic fundamentals have little explanatory power for nominal exchange rates. On the other hand, the recent microstructure approach to exchange rates' has shown that most exchange rate volatility at short to medium horizons is related to order flows. This...

Using a large sample of developing and industrialized economies during 1970-1999, this paper explores whether the choice of exchange rate regime affects the sensitivity of local interest rates to international interest rates. In most cases, we cannot reject full transmission of international...

This paper tests the portfolio-balance approach to exchange rate determination in a new way. Past work on portfolio balance in foreign exchange falls into two groups: (1) tests using measures of asset supply and (2) tests using measures of central-bank asset demand. We address the demand side,...

Macroeconomic models of nominal exchange rates perform poorly. In sample, R2 statistics as high as 10 percent are rare. Out of sample, these models are typically out-forecast by a na‹ve random walk. This paper presents a model of a new kind. Instead of relying exclusively on macroeconomic...

This paper surveys recent research in open-economy macroeconomics, using questions raised by European economic and monetary unification to guide the topics discussed. A striking empirical regularity is the tendency for changes in the nominal exchange rate regime systematically to affect the...

Many monetary and fiscal policy decision makers and economists hold the view that exchange rates are volatile even though nominal exchange rates vary less than many other financial market prices and yields. This paper seeks an explanation for this puzzle by contrasting exchange rate dynamics in...

This paper attempts to make the case that a 2-sector model using the familiar traded non-traded distinction offers a reasonably successful empirical account of why Mexico needed to devalue its exchange rate in 1994. This model provides a way to define and measure disequilibrium in the exchange...
