In this paper I examine optimal monetary policy and the informational implications of the Phillips curve in a stochastic model of a small open economy. It is assumed that the economy produces both traded and non-traded goods, that capital mobility is perfect and that the economy faces a variety...

This paper presents an investigation of the empirical significance of the Lucas Critique for the Phillips Curve. The investigation is carried out with annual historical time series for the United Kingdom (1857-1987) and the United States (1892-1987). The results, for two different models of the...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

Why is inflation so much lower and at the same time more stable in developed economies in the 1990s, compared with the 1970s? This paper suggests that the United Kingdom, United States and other countries may have escaped from a volatile inflation equilibrium. Our argument builds on the story...

The Paper extends Woodford’s (2000) analysis of the closed economy Phillips curve to an open economy with both commodity trade and capital mobility. We show that consumption smoothing, which comes with the opening of the capital market, raises the degree of strategic complementarity among...

This paper investigates the sources of the widely noticed reduction in the volatility of American business cycles since the mid 1980s. Our analysis of reduced volatility emphasizes the sharp decline in the standard deviation of changes in real GDP, of the output gap, and of the inflation rate....

This paper models Chinese inflation using an output gap Phillips curve. Inflation modelling for the world’s sixth largest economy is a still under-researched topic. We estimate a partially forward-looking Phillips curve as well as traditional backward-looking Phillips curves. Using quarterly...
