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...

The ongoing financial crisis is shaking central bankers’ certainties about their mission, and a rethinking of such mission can greatly benefit from a non-finalistic reassessment of how central banking has evolved over the centuries. This paper does so by taking a functional, instead of an...

This paper finds that asset prices on Oslo Stock Exchange is the single most important block of data to improve estimates of current quarter GDP in Norway. Other important blocks of data are labor market data and industrial production indicators. We use an approximate dynamic factor model that...

Most theoretical central bank models use short horizons and focus on a single tradeoff. However, in reality, central banks play complex, long-horizon games and face more than one tradeoff. We account for these issues in a simple infinite-horizon game with a novel tradeoff: higher rates deter...

This study reports the outcome of an effort to collect market price data for Norway with a view to constructing monthly price indices from the year 1777 to 1920. The material covers data on commodity prices from agriculture, shery, dairying, manufacturing and mining. Indices of the wholesale and...

This paper examines the impact of different types of oil price shocks on the U.S. economy, using a factor-augmented VAR (FAVAR) approach. The results indicate that when examining the effects of oil price shocks, it is important to account for the interaction between the oil market and the...

The paper presents an incomplete competition model (ICM), where inflation is determined jointly with unit labour cost growth. The ICM is estimated on data for the Euro area and evaluated against existing models, i.e. the implicit inflation equation of the Area Wide model (AWM) - cf. Fagan, Henry...

We investigate optimal horizons for targeting inflation in response to different shocks and their properties under alternative preferences of an inflation-targeting central bank. Our analysis is based on a well specified macroeconometric model of Norway, but we examine how alternative...

I document price adjustments in both high and low inflation years from 14 milllion monthly price observations of 1,133 goods and services. The variation in the frequency of price changes explains all the variation in the inflation rate. On average, prices increase more often when inflation is...

According to a Keynesian view, short term output fluctuations are normally demand side led. Since prices reflect demand, they should mirror output fluctuations. Thus, prices and output are expected to move in the same direction in the short run. The present paper investigates the historical...
