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...

This paper extends Galí and Gertler’s (1999) new hybrid KeynesianPhillips curve to the open economy context. We hypothesise that pricing decisionsdepend on both labour costs and intermediate imported input prices. The results forHong Kong are consistent with the theory if import prices are...

We examine the sources of macroeconomic economic fluctuations by estimating a variety of medium-scale DSGE models within a unified framework that incorporates regime switching both in shock variances and in the inflation target. Our general framework includes a number of different model features...

The strong response of long-term interest rates to macroeconomic shocks has typically been explained in terms of informational asymmetries between the central bank and private agents. The standard models assume that the equilibrium real interest rate is constant over time and independent of...

We propose an approach for Bayesian inference in time-varying structural vector autoregressions (SVARs) identified with sign restrictions. The linchpin of our approach is a class of rotation-invariant time-varying SVARs in which the prior and posterior densities of any sequence of structural...

We propose an event-study research design to identify the nature and propagation of large unusual shocks in DSGE models and apply it to study the macroeconomic effects of the Covid shock. The initial outbreak is represented as the onset of a new shock process where the shock loads on wedges...

This paper studies the effects of monetary policy shocks using structural vector autoregressions (SVARs). We achieve identification by imposing sign and zero restrictions on the systematic component of monetary policy. We consistently find that an increase in the fed funds rate induces a...

This paper analyses the use of factor analysis for instrumental variable estimation when the number of instruments tends to infinity. We consider cases where the unobserved factors are the optimal instruments but also cases where the factors are not necessarily the optimal instruments but can...

The estimation of dynamic factor models for large sets of variables has attracted considerable attention recently, due to the increased availability of large datasets. In this paper we propose a new methodology for estimating factors from large datasets based on state space models, discuss its...

Vi kartlegger årsakssammenhengen mellom pengemarkedsrenten og inflasjon gjennom en makroøkonometrisk modell. Modellen belyser også hvilke typer sjokk en har størst mulighet til å nøytralisere ved hjelp av moderate renteendringer, og hvilke målkonflikter som kan oppstå. I artikkelens...
