We propose a new methodology to study the stability of steady-state growth. Long-run GDP per capita can be characterized by: (1) the linear trend hypothesis, where there are no long-run changes in GDP levels or growth rates, (2) the level shift hypothesis, where there are long-run level shifts,...

Can US monetary policy in the 1970s be described by a stabilizing Taylor rule when policy is evaluated with real-time inflation and output gap data? Using economic research on the full employment level of unemployment and the natural rate of unemployment published between 1970 and 1977 to...

Measuring deviations from purchasing power parity has been the subject of extensive investigation. The most common practice in empirical research for measuring real exchange rate persistence is to estimate univariate autoregressive (AR) time series models and calculate the half-life, defined as...

We investigate two alternative versions of Purchasing Power Parity (PPP): reversion to a constant mean in the spirit of Cassel and reversion to a constant trend in the spirit of Balassa and Samuelson, using long-span real exchange rate data for industrialized countries. We develop unit root...

An extensive literature that studied the performance of empirical exchange rate models following Meese and Rogoff's [Meese, R.A., Rogoff, K., 1983a. Empirical Exchange Rate Models of the Seventies: Do They Fit Out of Sample? Journal of International Economics 14, 3-24.] seminal paper has not...
