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...

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 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...

We examine the value of sporting success to the German population at two major sport events in 2012, the European Championships in football and the London Olympic Games. Using the contingent valuation method (CVM), this study is the first to compare the value of sporting success between two...

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...

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...

World income grows fast without verifiable climate-change impacts on the economy. The growth spell can end if climate impacts turn real but this can take decades to learn. We develop a tractable stochastic climate-economy model with a hidden-state impact process to evaluate the contributions of...

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...
