Traditionell haben Finanz-Ökonomen Anlageentscheidungen im sogenannten "Mean-Variance-FrameworkX" von Markowitz (1952) evaluiert. Experimente haben jedoch gezeigt, dass die "Prospect Theory" von Kahneman und Tversky (1979) eine bessere Beschreibung der Entscheidungen von Anlegern unter...

I: Palm oil production creates negative externalities, e.g., through intensive fertiliser application. Policies to limit externalities need an effective, sustainable and efficient measure We use a business simulation game in a framed field experiment in Indonesia to test ex ante different...

Diese Dissertation besteht aus drei Aufsätzen, welche Themen aus dem Bereich Risiko-Beurteilung und Risiko-Management behandeln. Der erste Aufsatz in Kapitel 1 analysiert die Risikodynamik von Hedge Funds, indem neue Faktoren zur Risikobeurteilung eingeführt werden. Der zweite Aufsatz in...

For the procurement of complex goods the early exchange of information is important to avoid costly renegotiation ex post. We show that this is achieved by bilateral negotiations but not by auctions. Negotiations strictly outperforms auctions if sellers are likely to have superior information...

There is growing interest in the use of loss contracts that offer performance incentives as upfront payments that employees can lose. Standard behavioral models predict a tradeoff in the use of loss contracts: employees will work harder under loss contracts than under gain contracts; but,...

To reduce the load on cellular networks, offloading to Wi-Fi has long been discussed as a technological solution. Despite advances in scheduling algorithms and incentive schemes, most mobile operators do not actively promote Wi-Fi offloading and most Wi-Fi usage is limited to stationary in-home...

This paper employs firm-level panel data of 57 incumbent and entrant firms for 23 European countries in the decade from 2003 to 2012. We examine the impact of service- and facility-based competition on firm level investment as well as the strategic effects underlying infrastructure investment...

We develop and estimate a general equilibrium model in which monetary policy can deviate from active in.ation stabilization and agents face uncertainty about the nature of these deviations. When observing a deviation, agents conduct Bayesian learning to infer its likely duration. Under...

We present a new partial equilibrium theory of price adjustment, based on consumer loss aversion. In line with prospect theory, the consumers' perceived utility losses from price increases are weighted more heavily than the perceived utility gains from price decreases of equal magnitude. Price...

We consider a simple trading relationship between an expectation-based loss-averse buyer and profit-maximizing sellers. When writing a long-term contract the parties have to rely on renegotiations in order to ensure materially efficient trade ex post. The type of the concluded long-term contract...

Am Kapitalmarkt agierende Investoren zeigen Verhaltensweisen, die dem klassischen Verständnis von einem rational handelnden Individuum (Homo oeconomicus) widersprechen. Hierzu zählt auch das Phänomen des Dispositionseffektes. Der Dispositionseffekt führt zu einer schlechteren Wertentwicklung...

We present a new theory of wage adjustment, based on worker loss aversion. In line with prospect theory, the workers' perceived utility losses from wage decreases are weighted more heavily than the perceived utility gains from wage increases of equal magnitude. Wage changes are evaluated...

We study how website defaults affect consumer behavior in the domain of charitable giving. In a field experiment that was conducted on a large platform for making charitable donations over the web, we exogenously vary the default options in two distinct choice dimensions. The first pertains to...
