This paper presents a meta-analysis of 46 primary studies reporting a total of 108 genetically modified food valuation estimates. The analysis shows that elicitation methods and formats used in the primary studies affect valuation estimates much more than do sample characteristics. Moreover,...

We present a simple two-steps procedure for a within-subject test of the inequity aversion model of Fehr and Schmidt (1999). In the first step, subjects played modified ultimatum and dictator games and were classified according to their preferences. In the second step, subjects with specific...

This paper investigates in how far equity preferences may matter for climate negotiations. For this purposes we conducted a simple experiment with people who have been involved in international climate policy. The experiment, which was run via the Internet, consisted of two simple non-strategic...

We investigate the dynamic effects of a charitable lottery and an income tax on donations. The analysis is based on a two-round dictator game with the subject's charity of choice as recipient and additional incentives in the first round only. The immediate effect of a charitable lottery leads to...

Exemptions from costly policy measures are frequently applied to alleviate financial burdens to specific market participants. Using a stated-choice experiment with around 6,000 German household heads, we test how exemptions for low-income households and energy-intensive companies influence the...

Based on a survey among more than 5,000 German households and a single-binary choice experiment in which we randomly split the respondents into two groups, this paper elicits both households’ willingness to pay (WTP) for power supply security and their willingness to accept (WTA) compensations...

Based on hypothetical responses originating from a large-scale survey among about 6,000 German households, this study investigates the discrepancy in willingness-to-pay (WTP) estimates for green electricity across single-binary-choice and open-ended valuation formats. Recognizing that...

Public good games in coalitional form, such as the ones depicting international environmental agreements for the reduction of a global pollutant, generally foresee scarce levels of cooperation. The incentive to free ride, that increases for higher levels of cooperation, prevents the formation of...

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...

This paper investigates how competition and firm size affect the relationship between market uncertainty and R&D investment. We use an intuitively appealing measure of firm-specific uncertainty along with panel data to show that firms invest less in current R&D as uncertainty about market...
