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...

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...

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,...

Macht ist ein zentraler Bestandteil sozialer Interaktion. Obgleich eine Vielzahl gebräuchlicher Anschauungen und Begriffsdefinitionen zum Thema Macht existiert, erfordert ein wissenschaftlicher Umgang mit dem Konzept der Macht deren quantitative Operationalisierung. Der vorliegende Beitrag...

Forschung und Entwicklung (F&E) ist die Basis von marktfähigen Innovationen und besitzt damit einen zentralen Stellenwert für das Wirtschaftswachstum. Um die F&E-Tätigkeit von Unternehmen zu steigern, entwickelt die Politik gezielte Fördermaßnahmen, die beispielsweise in strukturschwachen...

Many of real-world public-goods are characterized by a marginal per capita return (MPCR) close to zero and have to be provided by large groups. Up until now, there is almost no evidence on how large groups facing a low MPCR behave in controlled public-good laboratory experiments involving...

This paper studies the variance risk premium from a new perspective by disaggregating the total premium into upper and lower semivariance premia. To this end, we provide novel tools for computing conditional expectations using traded options as well as moment generating functions. Across a...

In this note, we propose a method for efficient simulation of paths of latent Markovian state processes in a Markov Chain Monte Carlo setting. Our method harnesses available parallel computing power by breaking the sequential nature of commonly encountered state simulation routines. We offer a...

The Single-Picker Routing Problem deals with the determination of sequences according to which items have to be picked in a distribution warehouse and the identification of the corresponding paths which have to be travelled by human operators (order pickers). The Single-Picker Routing Problem...
