Abstract [en]

Interviews with Swedish authorities reveal large variations in the time horizons and discount rates used in their policy decisions. The time horizon, i.e. the future time period for which effects are included in the analysis, is seldom longer than 40-50 years, and nuclear waste is the only area in which a time horizon longer than 100 years is used regularly. Discount rates for non-commercial purposes vary between 2 per cent and 4 per cent, with 4 per cent as the most common rate. The differences between policy areas appear to be unsystematic and insufficiently justified. We suggest that there may be a need for coordination and, possibly, harmonization, of the choices of time horizons and discount rates.
