This paper experimentally investigates the effects of a costly punishment option on cooperation and social welfare in long finitely repeated public good contribution games. In a perfect monitoring environment increasing the severity of the potential punishment monotonically increases both...

We experimentally study the effect of auction format (sealed-bid vs. closed clock vs. open clock) and auction sequence (simultaneous vs. sequential) on bidding behaviour and auction outcomes in auctions of multiple related multi-unit items. Prominent field applications are the sale of emission...

This paper experimentally investigates how individual preferences, through unrestricted deliberation, are aggregated into a group decision in two contexts: reciprocating gifts and choosing between lotteries. In both contexts, we find that median group members have a significant impact on the...

Reciprocal feedback distorts the production and content of reputation information, hampering trust and trade efficiency. Data from eBay and other sources combined with laboratory data provide a robust picture of how reciprocity can be guided by changes in the way feedback information flows...

This paper revisits and extends the experiment on the solidarity game by Selten and Ockenfels (1998). We replicate the basic design of the solidarity game and extend it in order to t test the robustness of the ‘fixed total sacrifice’ effect and the applied strategy method. Our results only...
