In previous models of (cumulative) prospect theory reference-dependence of preferences is imposed beforehand and the location of the reference point is exogenously determined. This paper provides an axiomatization of a new specification of cumulative prospect theory, termed endogenous prospect...

Some path-breaking work on mergers takes efficiency gains for granted, or assumes that firms have perfect knowledge when taking merger decisions. In practice, firms and competition authorities cannot know exact future efficiency gains, prior to merger consummation. This paper analyzes horizontal...

In providing precautionary incentives and allocating environmental risk, liability for environmental damages faces two difficulties: randomness of damages incurred and nonobservability of precautionary measures. Hence, a major obstacle in enforcing legal claims is the difficulty of proving...

Analyzing a large weekly retail transaction price dataset, we uncover a surprising regularity— small price increases occur more frequently than small price decreases for price changes of up to about 10 cents, while there is no such asymmetry for larger price changes. The asymmetry holds for...

Apart from scaling up foreign aid by NGOs, informed choices of private donors could also encourage an efficient and targeted use of NGO funds in international development cooperation. We assess the determinants of private donations across a large sample of US based NGOs with foreign aid...

Reichen die auf dem G-20-Gipfel beschlossenen Maßnahmen aus, die Finanzmärkte zu regulieren und die Wahrscheinlichkeit zukünftiger Krisen zu senken? Für Rolf J. Langhammer, Institut für Weltwirtschaft, Kiel, dienten die Beschlüsse des G-20-Gipfels der Krisenüberwindung und dem Versuch,...

Common ratio effects should be ruled out if subjects' preferences satisfy compound independence, reduction of compound lotteries, and coalescing. In other words, at least one of these axioms should be violated in order to generate a common ratio effect. Relying on a simple experiment, we...

This paper analyzes insurance demand under prospect theory in a simple model with two states of the world and fair insurance contracts. We argue that two different reference points are reasonable in this framework, state-dependent initial wealth or final wealth after buying full insurance....

We present a preference foundation for Chance Theory (CT), a model of decision making under uncertainty where the evaluation of an act depends distinctively on its lowest outcome. This outcome is evaluated with the riskless value function u and the potential increments over it are evaluated by...

In an intensively discussed paper, Andreoni and Sprenger (2012) , henceforth A&S, present an experiment where subjects can allocate money between two different points of time under the condition of risk. A&S claim that their results refute discounted expected utility (DEU) as well as prospect...
