Should public assets such as infrastructure, education, and the environment earn the same return as private investments? The long-term nature of public investments provides commitment to current preferences, which justifies lower than private returns for time-inconsistent decision markers. An...

Climate is a persistent asset, bar none: changes in climate-related stocks have consequences spanning over centuries or possibly millennia to the future. To reconcile the discounting of such far-distant impacts and realism of the shorter-term decisions, we consider hyperbolic time-preferences in...

Uncertainty has an almost negligible impact on project value in the economic standard model. I show that a comprehensive evaluation of uncertainty and uncertainty attitude changes this picture fundamentally. The analysis relies on the discount rate, which is the crucial determinant in balancing...

As the most important driver of long-term project evaluation, from climate change policy to infrastructure investments, the social discount rate (SDR) has been subject to heated debate among economists. To uncover the extent and sources of disagreement, we report the results of a survey of over...

We examine the value of sporting success of the 2014 Football World Cup in Brazil by using a method that allows measuring non-market goods, the contingent valuation method (CVM). Besides the value of sporting success in form of the willingness-to-pay (WTP), we determine what influences the WTP...

The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model's descriptive power is comparable to numeric models used in policy advising....

The effects of a policy measure often reach the consumer only after one or more intermediatesteps, for instance because the measure lowers the cost of an input for an industry producinga consumer good. This paper is concerned with the question how to measure such indirect effectscorrectly under...

In many empirical Contingent Valuation studies one finds that household size, i. e. the number auf household members, is negatively correlated with stated household willingness to pay for the realization of environmental projects. This observation is rather puzzling because in larger households...

This paper uses the Kaldor-Hicks compensation principle to compute the present value (PV) of a non-marginal future event. Three theoretical results stand out: First, decreasing returns to capital create a wedge between the PV of future generations' willingness to pay (WTP) and the PV of their...
