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,...

We construct an agent-based New Keynesian DSGE model with different social network structures to investigate the significance of network topologies to macroeconomic stability. According to our simulation results, we find that the more liquid the information flow, the higher the stability of the...

This paper presents a simple experiment on how laypeople form macroeconomic expectations. Subjects have to forecast inflation and GDP growth. By varying the information provided in different treatments, we can assess the importance of historical time-series information versus information...

This paper develops a methodology for estimating the parameters of dynamic opinion or expectation formation processes with social interactions. We study a simple stochastic framework of a collective process of opinion formation by a group of agents who face a binary decision problem. The...

Conjectures about inflation expectations are inextricably linked to our understanding of the relationship between the real and monetary sides of the economy; yet, direct empirical research on the matter has been scarce at best. This paper therefore examines the empirical properties of inflation...
