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 high, and decrease more often when inflation is low. The...

We construct factor models based on disaggregate survey data for forecasting national aggregate macroeconomic variables. Our methodology applies regional and sectoral factor models to Norges Bank’s regional survey and to the Swedish Business Tendency Survey. The analysis identifies which of the pieces of information extracted from the individual re...

We explore the existence of downward real wage rigidity (DRWR) at the industry level, based on data from 19 OECD countries for the period 1973–1999. The results show that DRWR compresses the distributions of industry wage changes overall, as well as for specific geographical regions and time periods, but there are not many real wage cuts that are p...

A number of recent studies have documented extensive downward nominal wage rigidity (dnwr) for job stayers in many oecd countries. However, DNWR for individual workers may induce downward rigidity or “a floor” for the aggregate wage growth at positive or negative levels. Aggregate wage growth may be below zero because of compositional effects, for...

Både innføring av inflasjonsmål rundt årtusenskiftet og finanskrisen i 2008/09 endret hvordan makroøkonomi undervises på universiteter og høyskoler, se feks Blanchard (2016), Bowles og Carlin (2019), Carlin og Soskice (2015), Core (2017), Holden (2016) og WrenLewis (2015). En viktig endring fra ISLM-modeller som dominerte makrofaget tidligere, er a...

This paper documents a firm level dataset of hourly wages for skilled blue collar workers by profession in the Norwegian pulp and paper industry 1967–79.

This paper studies price dispersion in the Norwegian retail market for 766 products across 4,297 stores over 60 months. Price dispersion for homogeneous products is significant and persistent, with a coefficient of variation of 37 percent for the median product. Price dispersion differs between product categories and over time. Store heterogeneity...

This is the first paper documenting the frequency and size of price adjustments using micro data from both the high-inflation period in the 1970s and 1980s, and the period of low inflation since the early 1990s. When inflation is high and volatile, prices change more frequently and in smaller magnitudes. When inflation is low and stable, prices cha...

We study the possible existence of downward nominal wage rigidity (DNWR) at wage growth rates different from zero in aggregate data. Even if DNWR prevails at zero for individual workers, compositional effects might lead to falling aggregate wages, while changes in relative wages combined with DNWR might lead to positive aggregate wage growth. We ex...

We assess the forecast ability of Norges Bank’s regional survey for inflation, GDP growth and the unemployment rate in Norway. We propose several factor models based on regional and sectoral information given by the survey. The analysis identifies which information extracted from the ten sectors and the seven regions performs particularly well at f...

Recent microeconomic studies have documented extensive downward nominal wage rigidity (DNWR) for job stayers in many OECD countries, but critics argue that the effect might be undone by compositional changes and flexibility in wages of new entrants. Using data for hourly nominal wages at industry level, we explore the existence of DNWR on industry...

This paper explores the existence of downward real wage rigidity (drwr) in 19 oecd countries, over the period 1973–1999, using data for hourly nominal earnings at industry level. Based on a nonparametric statistical method, which allows for country and year specific variation in both the median and the dispersion of industry wage changes, we find e...

Based on a nonparametric statistical method, which allows for country- and year-specific variation in both the median and the dispersion of industry wage changes, we f...

This paper explores the existence of downward nominal wage rigidity (DNWR) in the industry sectors of 14 European countries, over the period 1973–1999, using a data set of hourly nominal wages at industry level. Based on a novel nonparametric statistical method, which allows for country and year-specific variation in both the median and the dispers...

This paper explores the existence of downward nominal wage rigidity (DNWR) in the manufacturing sectors of 14 European countries, over the period 1973-1999, using an unbalanced data set of hourly nominal wages at industry level. Based on a novel univariate statistical method, which allows for country and year specific variation in both the mean and...

The concept of core inflation is supposed to serve as a tool for monetary policy by indicating the trend component of inflation. In order to fulfill this task we argue that core inflation needs to be defined within an econometric model of the inflation mechanism. Furthermore, because monetary policy is forward looking this model must meet several d...

Wage determination in Norwegian industry is investigated using a panel of over 7,000 firms over 17 years. A standard right-to-manage bargaining model serves as theoretical background for the empirical specification. Wage equations focusing on the relative importance of insider vs outsider variables are estimated, controlling for firm-specific fixed...

Increased tax progressivity raises the elasticity of labour demand with respect to consumer wages which implies that labour unions subtitute wages with employment. This paper investigates the effects to tax prograssivity on wages using Nerwegian establishment level panel data.

Adjustment costs of labour motivates a dynamic labour demand equation which is estimated using different methods on a panel data set of 6281 Norwegian manufacturing firms from 1974-91. A 95% con�dence interval for the autoregressive coe�cient is (0.74,0.82) which indicates the impor- tance of adjustment costs to labour demand, is comparable to othe...

The Norwegian authorities pursue active labour market policies to fight unemployment by qualifying the unemployed in a wide range of programmes. We discuss theoretically and investigate empirically the effects such policies might have on the wage curve using a panel of more than 5400 Norwegian firms and regional unemployment figures. Total unemploy...

Med utgangspunkt i fagforeningsteori der bedrift og fagforening forhandler om lønna, analyseres lønnsdannelsen for fagarbeidere i norsk treforedlings-industri (paneldata). Et viktig skille i denne teorien går mellom interne og eksterne faktorer som kan påvirke lønnsdannelsen. Teorien for integrerte variable er sentral i utforming og tolking av en e...
