We develop an analytically tractable two-country model that marries a full account of global macroeconomic dynamics to a supply framework based on monopolistic competition and sticky nominal prices. The model offers simple and intuitive predictions about exchange rates and current accounts that...

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. However, the long samples required for statistical significance are unavailable for most currencies, and...

The central claim in this paper is that by explicitly introducing costs of international trade (narrowly, transport costs but more broadly, tariffs, nontariff barriers and other trade costs), one can go far toward explaining a great number of the main empirical puzzles that international...

Using the gravity model, we find evidence that the EC affects trade flows. A pair of EC members trade with each other 48 percent more than two otherwise similarly-placed countries. We also find that bilateral exchange rate variability fell by half within Europe during the 1980s, and that this...
