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...

This empirical study investigates whether and how much individuals are willing to pay for hosting Olympic Games in Germany. Moreover, it is examined for the first time what individuals are willing to accept to host Olympic Games in their own country if they do not like that. Furthermore, this...

In Stated Preference studies for the appraisal of environmental projects in poor countries or regions it often turns out that the stated willingness to pay of people for environmental improvements, which is used as measure of individual welfare changes, is very low. This is often interpreted as...

In "How should the distant future be discounted when discount rates are uncertain?" (2010) Gollier and Weitzman claimed having solved the Weitzman-Gollier puzzle, concluding from a risk-averse utility maximizing model that Weitzman discounting is qualitatively correct and that when uncertain...

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...

Through the Hartz reforms, German active labor market policy was fundamentally restructured and has since been systematically evaluated. This paper reviews the recent evaluation findings and draws some conclusions for the future setup of active labor market policies in Germany. It argues in...

This paper analyzes the effectiveness of occupational training programs for the unemployed before and after the substantial amendments in German labor market legislation known as Hartz reforms. Based on the official evaluation of the reforms, we show that program impacts vary much across...

There are many reasons to suspect that benefit-cost analysis applied to environmental policies will result in policy decisions that will reject those environmental policies. The important question, of course, is whether those rejections are based on proper science. The present paper explores...

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...

This paper examines implications of limits to substitution for estimating substitutability between ecosystem services and manufactured goods and for social discounting. Based on a model that accounts for a subsistence requirement in the consumption of ecosystem services, we provide empirical...
