We experimentally study the role of reputation in procurement using two common mechanisms: price-based and buyer-determined auctions. While buyers are bound to buy from the lowest bidder in price-based auctions, they can choose between bidders in buyer-determined auctions. Only in the latter...

Centipede games and Dutch auctions provide important instances in which game theory fails empirically. The reasons for these empirical failures are not well understood. Standard centipede games and Dutch auctions differ from each other in terms of their Institutional Format (IF), Dynamic...

We provide an overview of experimental literature on lottery contests and point out the two main phenomena observed in most contest experiments: overbidding relative to the standard Nash equilibrium prediction and heterogeneous behavior of ex-ante symmetric contestants. Based on the sample of...

We run experiments of first-price auctions with two groups, by which we directly detect the presence of bidders' loss aversion. Each human bidder bids against three pre-programmed computer bidders -- computers independently draw their values from the uniform distribution and bid their values in...

This paper reports the experimental results of implicit pre-play communication on the equilibrium selection in threshold public goods game experiments. The existence of an asset market in which the right to participate in a public goods game with a provision point is auctioned off among a larger...

The theoretical literature on collusion in auctions suggests that the first-price mechanism can deter the formation of bidding rings. In equilibrium, collusive negotiations are either successful or are avoided altogether, hence such analysis neglects the effects of failed collusion attempts. In...

In this study, we designed a delayed payment mechanism in laboratory second price auctions (SPAs) under which subjects received a cash endowment two weeks after the experiment day and had to use their own money to pay the experimental loss (if any) on the experiment day. We compared the effect...

In first- and second-price private value auctions with sequential bidding, second movers may discover the first movers' bid. Equilibrium behavior in the first-price auction is mostly unaffected but there are multiple equilibria in the second-price auction. Consequently, comparative statics...

We investigate experimentally whether emotions affect bidding behavior in a first price auction. To induce emotions, we confront subjects after a first auction series with a positive or negative random economic shock. We then explore the relation between emotions and bidding behavior in a second...

In an experiment using two-bidder first-price sealed bid auctions with symmetric independent private values, we scan also the right hand of each subject. We study how the ratio of the length of the index and ring fingers (2D:4D) of the right hand, a measure of prenatal hormone exposure, is...
