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....

This paper provides real-time evidence on the frequency, size, duration and economic significance of arbitrage opportunities in the foreign exchange market. We investigate deviations from the covered interest rate parity (CIP) condition using a unique data set for three major capital and foreign...

We employ a new decision-theoretic approach to dealing with Knightian uncertainty based on Simon's bounded rationality. The basic tool of this approach is a quantitative answer to the question: For a specified policy, among a set of policies, how much can our assumptions regarding e.g. model and...

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...

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...

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....
