We propose a new decision criterion under risk in which people extract both utility from anticipatory feelings ex ante and disutility from disappointment ex post. The decision maker chooses his degree of optimism, given that more optimism raises both the utility of ex ante feelings and the risk...

This paper uses laboratory experiments to provide a systematic analysis of how different presentation formats affect individuals' investment decisions. The results indicate that the type of presentation as well as personal characteristics influence both, the consistency of decisions and the...

We study the impact of coupling a decision maker’s lottery payoffs to those of a peer on the preferred level of risk by means of a lab experiment. Compared to the benchmark where the lotteries are paid off individually, symmetrically coupled payoffs increase the willingness to take risks,...

This study explores people's risk attitudes after having suffered large real-world losses following a natural disaster. Using the margins of the 2011 Australian floods (Brisbane) as a natural experimental setting, we find that homeowners who were victims of the floods and face large losses in...

Many important economic and political decisions are made by teams. In the economic literature, however, the decision units are frequently modeled as individual economic agents. The paper experimentally investigates the question to what extent observed team decisions under risk are actually...

The supposed irrelevance of historical costs for rational decision making has been the subject of much interest in the economic literature. In this paper we explore whether individual decision making under risk is affected by the cost of the supplied information. Outside of the lab, it is...
