In this paper, the authors report on a computer-based laboratory experiment
	investigating whether disclosing the buyer’s preferences in a multi-attribute
	reverse English auctions affects buyer’s utility, suppliers’ profits
	and efficiency. The results show that full revelation of the buyer’s
	preferences significantly increases allocational efficiency. Suppliers
	use the additional information in their bidding decisions and make
	weakly significantly more profits. However, the experimental evidence
	does not support the hypothesis that the buyer is better off when
	revealing her preferences. At least, the results indicate that the
	buyer is not exploited by suppliers.
