This paper discusses the properties of price- and Cost-of-Living indexes that follow from specific assumptions about the structure of consumer preferences. Of particular interest are indexes for elementary aggregates. In the first part of the paper we show how particular indexes for elementary...

In this paper, a subsystem of demand equations is estimated using data from the Norwegian survey of household expenditures 1989-1991. One objective has been to obtain substantial knowledge of Norwegian household demand for a set of food groups, with emphasis on price responses, using two...

Traditional approaches to consumer demand modelling ignores the problem associated with product heterogeneity where important product characteristics are latent. The point of departure in the present study is a particular framework developed in Dagsvik (1996a,b) and Dagsvik et al. (1998). In...

The output gap (measuring the deviation of output from its potential) is a crucial concept in the monetary policy framework, indicating demand pressure that generates inflation. The output gap is also an important variable in itself, as a measure of economic fluctuations. However, its definition...

We estimate a small open-economy DSGE model for Norway with two specifications of monetary policy: a simple instrument rule and optimal policy based on an intertemporal loss function. The empirical fit of the model with optimal policy is as good as the model with a simple rule. This result is...
