Der Kapitalwert lässt sich auch bei Null- und Negativzinsen zumindest über endliche Zeiträume einfach berechnen sowie betriebswirtschaftlich für Investitionsentscheidungen sinnvoll ver­wen­den. Volkswirtschaftlich ist relevant, warum es Zinsen von und unter null überhaupt gibt und ob...

In 2021, the Biden Administration issued mandates requiring COVID-19 vaccinations for U.S. federal employees and contractors and for some healthcare and private sector workers. Although these mandates have been subject to legal challenges and some have been halted or delayed, rigorous appraisal...

The estimated values to society from long-term public projects, including climate change mitigation and infrastructure construction, are highly sensitive to the social discount rate (SDR) employed. Governmental guidance on social discounting has predominantly been based on input from expert...

The appraisal of public investments is subject to formal guidelines which often require input prices, such as forecasted energy prices. Using Danish guidelines as a case study, we explore the discounting assumptions in these input prices and find rates ranging from 2.97% to 17.5%, markedly...

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...

While the global economy continues to grow, ecosystem services tend to stagnate or decline. Economic theory has shown how such shifts in relative scarcities can be reflected in project appraisal and environmental-economic accounting, but empirical evidence has been sparse to put theory into...

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...

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...
