We report on a series of experiments that examine bidding behavior in first-price sealed bid auctions with symmetric and asymmetric bidders. To study the extent of strategic behavior, we use an experimental design that elicits bidders' complete bid functions in each round (auction) of the...

This paper investigates experimentally how organisational decision processes affect the moral motivations of actors inside a firm that must forego profits to reduce harming a third party. In a "vertical" treatment, one insider unilaterally sets the harm-reduction strategy; the other can only...

We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we...

The paper reports on the effects of one-sided imperfect information on bidding behaviour in simultaneous and sequential first-price auctions of non-identical objects when bidders have multi-unit demands. The analysis provides the following four main results. First, when different objects are to...

Bidding challenges learning theories. Even with the same bid, experiences vary stochastically: the same choice can result in either a gain or a loss. In such an environment, the question arises of how the nearly universally documented phenomenon of loss aversion affects the adaptive dynamics. We...

Updated - please see paper 551.02 in this series. The Bank of Spain uses a unique auction format to sell government bonds, which can be seen as a hybrid of a uniform and a discriminatory auction. For winning bids above the average winning bid, buyers are charged the average winning bid,...
