Online auction platforms like eBay provide a wide range of auctions containing substitutable goods. Some of these auctions exhibit parallel elements which means that two or more auctions run side by side for a certain time. Experiments have shown that multiple auctions ending at the same time,...

This paper experimentally studies persuasion effects in ultimatum games and finds that Proposers' payoffs significantly increase if, along with offers, they can send messages which Responders read before their acceptance decision. Higher payoffs are due to higher acceptance rates as well as more...

In online auction platforms, offers are listed side by side and may end at the same point in time. While theoretical studies predict efficient coordination across auctions, experimental and empirical studies observe efficiency losses, i.e. goods remain unsold. In order to mitigate this...

Small monopoly trade unions decide upon the wage rate per hour and the hours of work subject to firm's demand for union members. Since the resulting Nash equilibrium is characterized by excess unemployment, we study the employment and welfare effects when trade unions try to coordinate their...

Experimental economists have discovered various violations of expected utility theory and offered alternative models that can explain laboratory results. This study discovers a new violation in risky choices that cannot be explained by theories like Prospect Theory, Disappoint- ment or Regret...

The use of screening contracts is a common approach to solve supply chain coordination problems under asymmetric information. One major assumption in this context is that subjects will rather use their private information strategically than to reveal them truthfully, if they do not get any...

This paper deals with credit market imperfections and idiosyncratic risks in a two–sector heterogeneous agent dynamic general equilibrium model of occupational choice. We focus especially on the effects of tightening financial constraints on macroeconomic performance, entrepreneurial...

Mit dem von P. Nyhuis und H.-P. Wiendahl entwickelten Konzept der logistischen Kennlinien ist das Ziel verbunden, den Zusammenhang zwischen verschiedenen Kenngrößen eines logistischen Systems mit einem einfachen Funktionsverlauf hinreichend genau abzubilden. Im Rahmen von Lagerkennlinien soll...

Das Bestandsmanagement von Ersatzteilen stellt Hersteller langlebiger Industrie- und Konsumgüter insbesondere in der Nachserienphase vor große Herausforderungen, da nach Abschluss der Serienproduktion die zur einer effizienten Bedarfsbefriedigung notwendige Flexibilität nur noch in...
