This paper presents a result of a voluntary contribution mechanism experiment with partial communication. We found that the trend of mean investments depended on whether a communication network was connected or not and on how fast all subjects could share information.

This paper reports experimental evidence on behaviour in an Ultimatum Game where responders have low structural information and feedback so that they have to learn the nature of the game during repeated play. The results lend support to the view that certain learning conditions are less...

In economics, adjustment of behavior has traditionally been treated as a "black box." Recent approaches that focus on learning behavior try to model, test, and simulate specific adjustment mechanisms in specific environments (mostly in games). Results often critically depend on distinctive...

This paper provides evidence that free riders are heavily punished even if punishment is costly and does not provide any material benefits for the punisher. The more free riders negatively deviate from the group standard the more they are punished. As a consequence, the existence of an...

This paper is on production planning and inventory control in systems where manufacturing and remanufacturing operations occur simultaneously. Typical for these hybridsystems is, that both the output of the manufacturing process and the output of the remanufacturing process can be used to...
