Many empirical studies of business cycles have followed the practise of applying the Hodrick-Prescott filter for cross-country comparisons. The standard procedure is to set the weight \lambda, which determines the 'smoothness' of the trend equal to 1600. We show that if this value is used for...

In this paper we study the macroeconomic effects of an inflow of low-skilled workers into an economy where there is capital accumulation and two types of agents. We find that there are substantial dynamic effects following unexpected migrations with adjustments that resemble those triggered by a...

We study the effects of German unification in a model with capital accumulation, skill differences and a welfare state. We argue that this event is similar to a mass migration of low-skilled agents holding no capital into a foreign country. Absent a welfare state, we observe an investment boom,...

This paper reconsiders the empirical evidence on the asymmetric output effects of monetary policy. Asymmetric effects is a common feature of many theoretical models, and there are many different versions of such asymmetries. We concentrate on the distinctions between positive and negative...

We study relative price behavior in an international business cycle model with specialization in production, in which a goods market friction is introduced through transport costs. The transport technology allows for flexible transport costs. We analyze whether this extension can account for the...
