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 article is related to the large recent literature on Phillips curves in sticky- price equilibrium models. It differs in allowing for the degree of price stickiness to be determined endogenously. A closed-form solution for short-term inflation is derived from the dynamic stochastic general...

In this paper I investigate the relationships between wage adjustment, competitiveness, macroeconomic policy and aggregate fluctuations in a small open economy. Based on a model of an economy producing both traded and non-traded goods, and assuming that the traded goods sector is competitive...

This paper presents a compact derivation of the determinants of changes in the equilibrium real exchange rate (the price index of non-traded goods relative to traded goods) in a small open economy with any number of goods and factors. It is shown that the change in the real exchange rate equals...

It is well known that the neoclassical model does not generate comovement among macroeconomic aggregates in response to news about future total factor productivity. We show that this problem is generally more severe in open economy versions of the neoclassical model. We present an open economy...

The recent volatility in global commodity prices and in the price of oil, in particular, has created renewed interest in the question of how monetary policy makers should respond to oil price fluctuations. In this paper, we discuss why this question is ill-posed and has no general answer. The...

We examine optimal policy in a two-country model with uncertainty and learning, where monetary policy actions affect the real economy through the real exchange rate channel. Our results show that whether policy should be cautious or activist depends on the size of one country relative to...

This paper estimates and tests a new Keynesian small open economy model in the tradition of Christiano, Eichenbaum, and Evans (2005) and Smets and Wouters (2003) using Bayesian estimation techniques on Swedish data. To account for the switch to an inflation targeting regime in 1993 we allow for...

We construct an open economy disequilibrium model to assess the welfare effects of aid in different macroeconomic regimes. Aid is shown to have different effects in different unemployment regimes because it increases the social costs of wage-price rigidities in the classical regime but decreases...

Recent empirical work has suggested that in response to a positive technology shock, labour productivity rises more than output, while employment shows a persistent decline. This finding has raised doubts concerning the relevance of the RBC model as well as the quantitative significance of...
