Another contested auction, and some precautions

In an earlier post, Auction disruption by fake bids, I followed an auction of Chinese artifacts that was opposed by the Chinese government, and was ultimately disrupted when the high bidder indicated that his bid was fraudulent. Today's news is of an auction in Manhattan of Gandhi memorabilia (a watch and some other personal property) opposed by the Indian government (which had offered a pre-emptive bid of $20,000 for the items in an attempt to halt the sale, and had obtained an injunction in an Indian court when this was refused): Gandhi Items Sold for $1.8 Million.

The high bidder was an Indian national who may or may not be planning to donate the items to the Indian government. The auction house took some steps intended to protect themselves against the kind of disruption by false bid that occurred in the auction of Chinese artifacts.

"For the first time, Antiquorum Auctioneers, which focuses on watches, is requiring banking references, said Mr. Maron, the chairman.
Recently, Cai Mingchao, a collector and auctioneer, raised an uproar after he submitted two winning bids for bronze sculptures from China’s Qing Dynasty at a Christie’s auction in Paris. Mr. Cai later refused to pay for the items, saying he had deliberately sabotaged the auction because the sculptures had been illegally looted in the 19th century from an imperial palace outside Beijing.
“We are concerned about what happened at Christie’s,” Mr. Maron said in a phone interview. "

Auction disruption by fake bids

In an earlier post, Markets and Fraud, I discussed the case of an environmental activist who disrupted an auction for oil and gas drilling rights by submitting the winning bids on several tracts. Now comes a report of an auction by Christies of some Chinese bronzes that the Chinese government claims as national cultural artifacts: Chinese Man Bids but Won’t Pay for Looted Bronzes , and Chinese Bidder Says He Won’t Pay for Looted Bronzes

"A man claiming to be the mysterious bidder who bought two Qing dynasty bronzes at an auction in Paris surfaced Monday, saying it was his patriotic duty to refuse to pay the $40 million winning bid.
A Chinese collector and auctioneer, Cai Mingchao, said at a news conference in Beijing he had made the anonymous winning bids for the 18th-century bronze heads of a rat and a rabbit. He described himself as a consultant with the Lost Cultural Relics Recovery Program, a nongovernmental group that seeks to bring looted artifacts back to China.
...
"On moral grounds, and as a way to protest the auction, Mr. Cai added, “I want to emphasize that the money won’t be paid.”"


"The Chinese government had attempted to halt the sale of the relics, saying they should be returned, not sold.
However, the government denied having anything to do with the fake bid."
...
"In a statement, Christie's said: ''We are aware of today's news reports. As a matter of policy, we do not comment on the identity of our consignors or buyers, nor do we comment or speculate on the next steps that we might take in this instance.''"

One aspect of auction design that may need greater attention if these kinds of disruptions become commonplace is how to qualify and verify bidders and winners, and notify other bidders in the event that winners default, so that auctions can be made more resistant to attack by fake bidders.

Market for honey: "honey laundering"

'Honey laundering' beats US tariffs on Chinese food products (I couldn't resist a new criminal activity with such a great name...)

"As the name suggests, honey laundering involves disguising drums of the sticky stuff from China by selling it to a third party—usually a distributor in another part of the world—then re-packaging it and re-exporting it, so that its source remains unknown. ...
As harmless as honey laundering might sound, health officials say that unless something is done, the problem could result in a repeat of the tainted baby milk and pet food scandals that dominated headlines this year—this time with honey. The reason dates back to 1997 when Chinese bee hives were almost wiped out by a bacterial epidemic. Instead of destroying the hives, beekeepers treated them with chloramphenicol, a toxic antibiotic... The practice has since been outlawed by China’s Ministry of Agriculture, but even today, some Chinese honey remains tainted—hence the fact that random checks on shipments are carried out at US ports. "

Markets and fraud

You can't read the news these days without thinking about fraud, and how market designers should think about it. I don't just mean headline grabbing Ponzi schemes of unprecedented proportions either, but run of the mill misbehavior. Part of the answer involves regulation, legislation, law enforcement, and the profession of accountancy. There's even an Association of Certified Fraud Examiners.

Scott Kominers (an aspiring market designer who is applying to grad schools this year, and looks like a hot prospect) draws my attention to a case that might fall under the heading of environmental activism: Bidder said it was easy to rig government auction.

Scott writes:
"Apparently, "Tim DeChristopher, 27, a University of Utah economics student and environmental activist," infiltrated the government oil and gas parcel auction. 'He snapped up 22,500 acres of parcels between Arches and Canyonlands national parks that he doesn't plan to develop or even pay for. He also drove up prices on other bids by hundreds of thousands of dollars.' Proof that those who do not practice safe market design are doomed to be beaten by economics students."

Black market in poverty--fraudulent ration cards

The Hindu reports: Hi-tech foodgrains rationing system introduced for below poverty line families

"Bangalore: The State Government has introduced a hi-tech rationing system which will ensure the timely supply of foodgrains to people living below the poverty line and simultaneously prevent black-marketing and circulation of bogus ration cards. ...
"Governments in the State over the past three decades have found it difficult to check the rampant black-marketing in foodgrains and circulation of bogus ration cards, although it is evident that politicians have been behind the large-scale issue of below poverty line cards in exchange for votes.

Financial Fraud, and law enforcement

Some parts of market design involve criminal law, and these depend for their effectiveness on law enforcement. The NY Times reports that the
F.B.I. Struggles to Handle Wave of Financial Fraud Cases

"The bureau slashed its criminal investigative work force to expand its national security role after the Sept. 11 attacks, shifting more than 1,800 agents, or nearly one-third of all agents in criminal programs, to terrorism and intelligence duties. Current and former officials say the cutbacks have left the bureau seriously exposed in investigating areas like white-collar crime...
"So depleted are the ranks of the F.B.I.’s white-collar investigators that executives in the private sector say they have had difficulty attracting the bureau’s attention in cases involving possible frauds of millions of dollars."
