The value of preventing a fatality or (saving) a statistical life is an important question in health economics as well as environmental economics. This paper reviews and adds new insights to several of the issues discussed in the literature. For example, how do we define the value of a...

The European Union’s Emissions Trading System, EU ETS, has been reformed, shifting the system from a fixed-cap system into a system with an endogenous supply of permits. This paper discusses how to handle the scheme in project appraisal. The focus is on a few relatively straightforward...

The European Union's Emissions Trading System is the largest system in the world for trade in greenhouse gases. It used to be a cap-and-trade scheme with a fixed supply of permits. However, a recent reform of the system "punctures the waterbed" by making the supply of permits endogenous. The...

We estimate the effects of the implementation of a compulsory work injury insurance in Sweden in 1978 on compensating wage differentials. This involves two steps. First, we investigate if there are compensating wage differentials on the Swedish labor market and second, we assess if these were...

The effect of economic incentives on worker absenteeism is analyzed using panel data on work absence behavior for each day during 1990 and 1991 (i.e., 730 observations in the time dimension) for a representative sample of 1,396 Swedish blue collar workers. During the observed time period, a...

This paper discusses how to evaluate a large project when there is a substitute. The new large project causes discrete price adjustments in the substitute market. For example, a new high-speed rail may shift the demand curve for flight tickets to the left and reduce their price, in turn shifting...

Abadie and Imbens (2008, Econometrica) showed that classical bootstrap schemes fail to provide correct inference for K-nearest neighbour (KNN) matching estimators of average causal effects. This is an interesting result showing that bootstrap should not be applied without theoretical...
