Collusive agreements are often observed in procurement auctions. They are probably more easily achieved when competitors’ costs are easily estimated. If, however, the individual costs of bidders are private information, effective ring formation is difficult to realize. We compare...

Does geographic or (perceived) social distance between subjects signi?cantly affect proposer and responder behavior in ultimatum bargaining? To answer this question, subjects once play an ultimatum game with three players (proposer, responder, and dummy player) and asymmetric information (only...

We study an ultimatum experiment in which the responder does not know the offer when accepting or rejecting. Unconditional veto power leads to acceptances, although proposers are significantly greedier than in standard ultimatum games, and this is anticipated by responders.

We experimentally investigate competition for innovations in a patent race scenario. Pairs of subjects compete as seller firms on a duopoly market, investing in risky search. Successful innovations resulting thereof are rewarded via temporary monopoly rents. Classifying investor types reveals...

For given product specifications by two competing firms the demand levels are determined by a randomly generated ideal composition of aspects. Firms can vary some demand. Although the product space is much too large to be explored systematically, we expect (and test for) rather reasonable...

We experimentally investigate four allocation mechanisms - all based on the fair division approach, with varying bid elicitation methods and price rules - in terms of their allocation efficiency, distributional effects, and regularities in individual bidding behavior. In a repeated design, an...

In an experimental setting, firms in a duopoly market engage in a patent tournament and compete for profit-enhancing product advancements. The firms generate income by matching exogenously defined demand preferences with an appropriately composed product portfolio of their own. Demand...

We experimentally explore individual and competitive search, and we test whether generally accepted principles of bounded rationality adequately explain observed search behavior. Subjects can, at a cost, employ screening and selection methods not only facilitating search but also directly...
