Auctioning fresh fish, quickly. by Hafalir, Kesten, Sherstyuk and Tao

 Here's an auction for when leisurely price discovery is costly.

When Speed is of Essence: Perishable Goods Auctions by Isa Hafalir, , Onur Kesten, , Katerina Sherstyuk, , Cong Tao.  December 2023

Abstract: We study a remarkable auction used in several fish markets around the world, notably in Honolulu and Sydney, whereby high-quality fish are sold fast through a hybrid auction that combines the Dutch and the English formats in one auction. Speedy sales are of essence for these perishable goods. Our theoretical model incorporating “time costs” demonstrates that such Honolulu-Sydney auction is preferred by the auctioneer over the Dutch auction when there are few bidders or when bidders have high time costs. Our laboratory experiments confirm that with a small number of bidders, Honolulu-Sydney auctions are significantly faster than Dutch auctions. Bidders overbid in Dutch, benefiting the auctioneer, but bidding approaches risk-neutral predictions as time costs increase. Bidders fare better in the Honolulu-Sydney format compared to Dutch across all treatments. We further observe bidder attempts to tacitly lower prices in Honolulu-Sydney auctions, substantiating existing concerns about pricing in some fish markets.

From the introduction:

"We explore a seemingly peculiar and largely under-studied dynamic auction format employed in several perishable goods markets around the world, such as in Honolulu and Sydney fish markets. In this auction, the auctioneer sets a starting price that is neither as low as in an English auction nor as high as in a Dutch, but at a middle ground, allowing bidders to bid at the onset (either by raising their hands during a verbal Honolulu auction or by clicking a button during an automated Sydney clock auction). If at least one bidder bids, the auction proceeds as an English (ascending price) auction. If there is no initial interest, the price begins to drop, as in a Dutch (descending price) auction. However, once a bidder bids, other bidders are allowed to counter-bid, potentially reverting the auction to an English auction. Although this auction format has been documented (Feldman, 2006) and is apparently employed in a number of fish markets in France and Denmark (Guillotreau and Jim´enez-Toribio, 2006; Laks´a and Marszalec, 2020) as well as in Honolulu and Sydney,2 little is understood about the reasons for its emergence and its advantages over more traditional descending-only Dutch auction that is also commonly used for perishable goods."

Abstract

Standard auction formats feature either an upper bound on the equilibrium price that descends over time (as in the Dutch auction) or a lower bound on the equilibrium price that ascends over time (as in the English auction). We show that in some settings with costly information acquisition, auctions featuring both (viz., a narrowing channel of prices) outperform the standard formats. This Channel auction preserves some of benefits of both the English (truthful revelation) and Dutch (security for necessary information acquisition) auctions. Natural applications include housing, online auction sites like eBay, recording transactions on blockchains, and spectrum rights.
