Firms with a reputation as socially responsible may have an important cost advantage: If workers prefer their employer to be socially responsible, equilibrium wages may be lower in such firms. We explore this hypothesis, combining Norwegian register data with data on firm reputation collected by...

Applications of the DEA models show that inadequate results may arise in some cases, two of these inadequacies being: a) too many efficient units may appear in some DEA models; b) a DEA model may show an inefficient unit from the point of view of experts as an efficient one. The purpose of this...

The two fund separation property of the elliptical distributions is extended to the skew-elliptical and by adding a number of funds equalling the rank of the skewness matrix. Some elements of the generalization to singular extended skew-elliptical distributions are covered.

Measuring productive efficiency is an important research strand within fields of economics, management science and operations research. One definition of efficiency is the proportional scaling needed for observations of an inefficient unit to be projected onto an efficient production function...

The purpose of this paper is to estimate wage effects of occupational pensions, exploiting the introduction of mandatory occupational pensions in Norway as a source of exogenous variation in pension coverage. Various difference-in-differences models are estimated on a large sample of Norwegian...

Since governments can influence the demand for a new abatement technology through their environmental policy, they may be able to expropriate innovations in new abatement technology ex post. This suggests that incentives for environmental R&D may be lower than the incentives for market goods...

We investigate empirically the effect of government purchases on unemployment in 20 OECD countries, for the period 1960-2007. Compared to earlier studies we use a data set with more variation in unemployment, and which allows for controlling for a host of factors that influence the effect of...

We use a two-period model to investigate intertemporal eects of cost reductions in climate change mitigation technologies for the power sector. With imperfect climate policies, cost reductions related to carbon capture and storage (CCS) may be more desirable than comparable cost reductions...

Under the current market structure in the TV industry advertising prices are typically set by TV channels while viewer prices are set by distributors (e.g., cable operators). The latter implies that the distributors partly internalize the competition between the TV channels, since they take into...

The new-Keynesian Phillips curve (NKPC) includes expected future inflation to explain current inflation. Such models are estimated by replacing the expected value by the future outcome, using InstrumentalVariables or Generalized Method of Momentsmethods. However, the underlying theory does not...
