We investigate the importance of employing a valid model for monetary policy analysis. Specifically, we investigate the economic significance of differences in specification and empirical validity of models. We consider three alternative econometric models of wage and price inflation in Norway....

We investigate whether a decline in real interest rates and the US dollar contribute to higher commodity prices, and whether commodity prices tend to display overshooting behavior in response to changes in especially real interest rates. We analyze the behavior of a broad range of real commodity...

We employ information-gap decision theory to derive a robust monetary policy response to Knightian parameter uncertainty. This approach provides a quantitative answer to the question: For a specified policy, how much can our models and data err or vary, without rendering the outcome of that...

This paper investigates the presence and characteristics of arbitrage opportunities in the foreign exchange market using a unique data set for three major capital and foreign exchange markets that covers a period of more than seven months at tick frequency, obtained from Reuters on special...

This paper investigates the validity of the law of one price (LOP) in international financial markets by examining the frequency, size and duration of inter-market price di erentials for borrowing and lending services (`one-way arbitrage'). Using a unique data set for three major capital and...

Denne artikkelen undersøker hvor mye vi bør bruke av petroleumsinntektene hvis vi samtidig skal minimere kostnadene ved å bruke dem. Slike kostnader forbindes med sektoromstillinger som ikke kan opprettholdes og må reverseres for unngå intern og ekstern ubalanse i økonomien....

We investigate whether overnight interbank loans and interest rates can be reliably inferred at the market and bank level from central banks' interbank payments data. We identify overnight loans and interest rates among interbank payments for 11 banks in Norway and compare them with the actual...

We employ the robust-satisficing approach to derive robust monetary policy when parameters of a macro model are uncertain. There is a trade-off between robustness of policies and their performance. Hence, under uncertainty, the policy maker is assumed to be content with policy performance at...

We characterise the behaviour of Norwegian output, the real exchange rate and real money balances over a period of almost two centuries. The empirical analysis is based on a new annual data set that has recently been compiled and covers the period 1830-2003. We apply multivariate linear and...

This paper addresses the so-called natural resource curse by devising a rule that can reduce macroeconomic costs associated with the consumption of revenues from natural resources. It assumes that such macroeconomic costs are mainly brought about by changes in the real exchange rate, which...
