This paper provides the results of a field test of contingent valuation estimates within a willingness to accept framework. Using dichotomous choice questions in telephone- mail-telephone interviews, we compare responses to real and hypothetical offers to survey respondents for the opportunity...

This paper investigates consumer choices in the presence of conflicting goals, with and without information making conflicts salient. An experimental online study was conducted with a sample of German consumers, focusing on pig farming. The results show that personal health benefits outweigh...

A number of self-beneficial motives can trigger pro-environmental and prosocial behavior of individuals. We focus on the role of the warm glow of giving-the personal benefit people experience when doing good irrespective of the consequences-in the valuation of ethically certified food products....

This paper explores potential endowment effects of contractual default rules. For this purpose, we analyze the Hadley liability default clause in a model of bilateral bargaining of lotteries against safe options. The liability default clause determines the right for the safe payoff option. We...

Overall, 72 subjects invest their endowment in four risky assets. Each com-bination of assets yields the same expected return and variance of returns. Illusion of expertise prevails when one prefers nevertheless the self-selected portfolio. After being randomly assigned to groups of four...

We replicate three pricing tasks of Gneezy, List and Wu (2006) for which they document the so-called uncertainty effect, namely, that people value a binary lottery over non-monetary outcomes less than other people value the lottery's worse outcome. While the authors implemented a verbal lottery...

We investigate whether the value of time (VOT) depends on when the corresponding preferences are measured: in advance, just before, or after the time period for which the time preferences are being evaluated. We find that the VOT is highest when elicited just before the time period. This is an...

This study tests the hypothesis that hypothetical bias may not be related to value elicitation; rather it may be a value formation problem. When participants are asked to indicate their willingness to pay for an induced value good, we find no evidence of hypothetical bias for three different...

This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes towards risk and attitudes towards...

Models can be wrong and recognising their limitations is important in financial and economic decision making under uncertainty. Robust strategies, which are least sensitive to perturbations of the underlying model, take uncertainty into account. Finding the explicit set of alternative models...
