Signalling in auctions: Experimental evidence

Journal of Economic Behavior and Organization, 187, s. 448- 469. Doi: 10.1016/j.jebo.2021.04.001

We study the relative performance of the first-price sealed-bid auction, the second-price sealed-bid auction, and the all-pay sealed-bid auction in a laboratory experiment where bidders can signal information through their bidding behaviour to an outside observer. We consider two different information settings: the auctioneer reveals either the identity of the winning bidder only, or she also reveals the bidders’ payments to an outside observer. We find that the all-pay sealed-bid auction in which the bidders’ payments are revealed outperforms the other mechanisms in terms of revenue, while this mechanism underperforms in terms of efficiency relative to the winner-pay auctions.

Firm-specific information and explicit collusion in experimental oligopolies

European Economic Review, 82, s. 132- 141. Doi: 10.1016/j.euroecorev.2015.11.002

We experimentally study the effect of information about competitors’ actions on cartel stability and firms’ incentives to form cartels in Cournot markets. As in previous experiments, markets become very competitive when individualized information is available and participants cannot communicate. In contrast, when communication is possible, results reverse: markets become less competitive and cartels become more stable when individualized information is available. We also observe that the extra profits that firms obtain thanks to the possibility to communicate are higher when individualized information is present, suggesting that firms have greater incentives to form cartels in that situation
