Empirical relationships between crude oil prices and exchange rates of oil exporting countries tend to vary over time. I use econometric models of the norwegian and canadian nominal exchange rates to investigate whether such time-variation could reflect shifts in the key oil price drivers over...

We investigate the economic significance of trading off empirical validity of models against other desirable model properties, and the potential loss from ’overestimating’ model uncertainty and basing monetary policy on a relatively robust model, or on a suite of models. We find that...

Kompetanseforskjeller mellom innvandrere og innfødte arbeidere kan være én mulig årsak til at de har ulik ledighets- og sysselsettingsmønster. Innvandrere står overfor en mer usikker avkastning på investeringer i humankapital enn innfødte arbeidere. De står f.eks. overfor en...

This paper tests for multiple equilibria in the Norwegian unemployment rate and investigates whether it displays asymmetric response to positive and negative shocks. Linear and nonlinear univariate models are employed to account for the unemployment behaviour over the period 1972-1997. Among...

Despite the emerging consensus on the validity of purchasing power parity (PPP) between trading countries in the long run, empirical evidence in favour of the PPP theory is scarce in data predominantly exposed to real shocks. This paper tests for PPP between Norway and its trading partners using...

Major changes in the Norwegian exchange rate have often coincided with large fluctuations in the price of crude oil. Previous empirical studies have however suggested a weak and ambiguous relation between the oil price and the exchange rate. In contrast to these studies, this paper explores the...

Empirical and theoretical studies suggest that employment behaviour varies with the state of the labour market since hiring and firings costs depend on the availability of labour. Extending earlier empirical work on this subject, we test for state dependence in employment adjustment and in the...

Existing studies generally reject purchasing power parity (PPP) on datasets from countries that have been affected by large real shocks, including Norway. However, we offer strong evidence of PPP between Norway and its trading partners during the post-Bretton Woods period, in which the Norwegian...
