A standard model of equilibrium unemployment consists of static equations for real wage ambitions (wage curve) and real wage scope (price curve), which jointly determine the NAIRU. The heuristics of the model states that unless the rate of unemployment approaches the NAIRU from any given initial...

This paper uses imperfect competition as a basis for modelling the export price for an aggregated commodity produced by the Norwegian private mainland economy. The long run solution is analysed using a cointegration technique. The dynamics are modelled according to two different approaches; a...

We examine estimation of a model of producer behavior in the presence of correlated measurement errors in the regressors. Scale economies and price-cost margins are estimated from a set of panel data for manufacturing plants. The paper presents a somewhat new model for estimation of these...

The Norwegian export price for an aggregated commodity is modelled assuming price-setting behaviour. The focus is on the choice between backward- and forward looking models. The dynamics is modelled according to three different approaches; a backward looking error correction model and two...

This paper explores the inconsistency of common scale estimators when output is proxied by deflated sales, based on a common output deflator across firms. The problems arise when firms operate in an imperfectly competitive environment and prices differ between firms. In particular, we show that...

The paper analyses the price on domestic market for an aggregate commodity produced by Norwegian private mainland economy. The long-run solution is modelled assuming imperfect competition. The elasticities with respect to unit labour costs and competing prices vary with an indicator for...
