Increasing energy efficiency is a key global policy goal for climate protection. An important step towards an optimal reduction of energy consumption is the identification of energy saving potentials in different sectors and the best strategies for increasing efficiency. This paper analyzes...

Identifying the incidence of free-ridership is significant to a range of issues relevant to program evaluation, including the calculation of net program benefits and more general assessments of political acceptability. Estimates of free-ridership in the area of energy policy frequently rely on...

Based on the seminal paper of Farrell (1957), researchers have developed several methods for measuring efficiency. Nowadays, the most prominent representatives are nonparametric data envelopment analysis (DEA) and parametric stochastic frontier analysis (SFA), both introduced in the late 1970s....

The proliferation of instruments targeted at combatting climate change necessitates evidence-based evaluation to identify strategies that are not only effective and cost-efficient, but also supported by the population. In Germany, the data needed to support such analysis is scarce, however. A...

Communication is well known to increase cooperation rates in social dilemma situations, but the exact mechanisms behind this have been questioned and discussed. This study examines the impact of communication on public good provisioning in an artefactual field experiment conducted with 216...

The allure of an environmentally benign, abundant, and cost-effective energy source has led an increasing number of industrialized countries to back public financing of renewable energies. Germany's experience with renewable energy promotion is often cited as a model to be replicated elsewhere,...

This article revisits an analysis by Frondel, Ritter and Schmidt (2008) of Germany's Renewable Energy Act, which legislates a system of feed-in tariff s to promote the use of renewable energies. As in the original article, we argue that Germany's support scheme subsidizes renewable energy...

The increasing use of food commodities for biofuel production has substantial impact on prices and quantities of these and other food commodities. It is therefore likely that this trend also intensifies the competition for arable land. However, evidence for this hypothesis is generated by...

Using detailed data originating from several hundred households of the German Residential Energy Survey (GRECS), this paper empirically investigates the returns on investment in home-equipped photovoltaics (PV) installations. We find that these returns were particularly high in the years 2009 to...

Interactions among peers of the same social network play significant roles in facilitating the adoption and diffusion of modern technologies in poor communities. We conduct a large-scale randomized controlled trial in rural India to identify the impact of information from friends on willingness...
