Previous time-series studies have shown evidence of mean-reversion in real exchange rates. Deviations from purchasing power parity (PPP) appear to have half-lives of approximately four years. The long samples required for statistical significance are unavailable for most currencies, however, and...

Both the literature and new empirical evidence show that exchange rate regimes differ primarily by the noisiness of the exchange rate, not by measurable macroeconomic fundamentals. This motivates a theoretical analysis of exchange rate regimes with noise traders. The presence of noise traders...

Exchange rate regimes differ primarily by the activity of the exchange rate, not observable macroeconomic ‘fundamentals’. Fixed exchange rates are typically stable and floating exchange rates are volatile, but macro phenomena are regime-independent. Fundamentals only seem to be relevant for...

Gravity-based cross-sectional evidence indicates that currency unions stimulate trade; cross-sectional evidence indicates that trade stimulates output. This paper estimates the effect that currency union has, via trade, on output per capita. We use economic and geographic data for over 200...

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

While overall inflation has fallen dramatically in countries like Italy and Spain, inflation in the home good sector remains stubbornly higher than inflation in the traded good sector. If nominal exchange rates are fixed, these real appreciations imply an inflation differential with countries...

A democratic society in which the distribution of wealth is unequal elects political parties which tend to represent the interests of the poor. The clientele of such governments favour unanticipated inflation taxes to erode the real value of debt service and redistribute income from the rich to...

We analyse the proposed ‘stability pact’ for countries joining a European Monetary Union (EMU). Within EMU shortsighted governments fail to fully internalize the inflationary consequences of their debt policies, which results in excessive debt accumulation. Hence, although in the absence of...

We explore endogenous monetary unification in the context of a model in which a country with serious structural distortions (and, hence, high inflation) is admitted into a monetary union once its economic structure has converged sufficiently towards that of the existing participants. If...
