This paper analyses the dynamic effects of aggregate demand, supply and real oil price shocks on real output and unemployment. Oil price shocks are included explicitly in the model, to investigate their role in explaining periods of global recessions. The different structural disturbances are...

This paper analyses the sources of business cycles in economies that have an important energy producing sector. Especially, I investigate the effects of oil and gas extractions (energy booms) on the manufacturing sector, and analyse whether there is any evidence of a "Dutch disease", that is...

This paper calculates core inflation, by imposing long run restrictions on a structural vector autoregression (VAR) model containing the growth rate of output, inflation and oil prices. Core inflation is identified as that component in inflation that has no long run effect on output. No...

Modelling the Norwegian exchange rate against a basket of currencies, we find a robust long-term link between the real exchange rate and real interest differential that is consistent with purchasing power parity (PPP) and uncovered interest parity (UIP). However, PPP alone is rejected. These...

This paper analyses the role of real and nominal shocks in explaining business cycles in a small open economy like that of Norway. In particular, we study the sources behind real exchange rate fluctuations since the collapse of the Bretton Woods agreement. Imposing long run restrictions implied...

This study compares the forecasting performance of a structural exchange rate model that combines the purchasing power parity condition with the interest rate differential in the long run, with some alternative models. The analysis is applied to the Norwegian exchange rate. The long run...

This paper addresses the purchasing power parity (PPP) puzzle for commodity currencies. A substantial part of the literature on commodity currencies has found that, despite controlling for the effect of commodity prices, PPP does not hold in the long run. We show that once we also control for...
