After a forecast failure, a respecification is usually necessary to account for the data ex post, in which case there is a gain in knowledge as a result of the forecast failure. Using Norwegian consumption as an example, we show that the financial deregulation in the mid 1980s led to forecast...

A framework for forecasting new COVID-19 cases jointly with hospital admissions and hospital beds with COVID-19 cases is presented. This project, dubbed CovidMod, produced 21-days ahead forecasts each working day from March 2021 to April 2022, and forecast errors that were used to assess...

The dynamic properties of the The New Keynesian Phillips curve (NPC) is analysed within the framework of a small system of linear di.erence equations.We evaluate the empirical results of existing studies which uses ‘Euroland’ and US data. The debate has been centered around the...

Several features of the U.S. natural rate of unemployment are reconsidered through specification and testing of econometric models. Traditionally, the choice has been between a wage Phillips curve model, PCM, or an equilibrium correction wage curve model, WECM. The models proposed in this paper...

We specify an empirical model of US inflation which has the dynamics of wage and price setting at its core. In the dynamic wage equation an equilibrium-correction term connects the wage level to industrial prosperity indicators. In that way, the role of wage setting in the dynamics of the...

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...
