Helmet laws and organ donors

Would it be repugnant to have a state helmet/donor law that said you are free to ride a motorcycle without wearing a helmet, but when you do so you assert that you wish to be an organ donor in the event of a fatal accident?

Here's a paper from 2011 that suggests such a law might have some effect, since apparently helmet laws reduce organ donations.

Donorcycles: Motorcycle Helmet Laws and the Supply of Organ Donors

Stacy Dickert-ConlinTodd Elder ( and Brian Moore
Journal of Law and Economics, 2011, vol. 54, issue 4, pages 907 - 935
Abstract: Traffic safety mandates are typically designed to reduce the harmful externalities of risky behaviors. We consider whether motorcycle helmet laws also reduce a beneficial externality by decreasing the supply of viable organ donors. Our central estimates show that organ donations resulting from fatal motor vehicle accidents increase by 10 percent when states repeal helmet laws. Two features of this association suggest that it is causal: first, nearly all of it is concentrated among men, who account for over 90 percent of all motorcyclist deaths, and second, helmet laws are unrelated to the supply of donors who die in circumstances other than motor vehicle accidents. The estimates imply that every death of a helmetless motorcyclist prevents or delays as many as .33 death among individuals on organ transplant waiting lists.

Here's a related news story that came up when I searched:

Repugnance of animal sales by zoos

Luke Stein writes to me:

"As the consummate collector of repugnant market stories, I thought you might be interested in a recent NPR story on the exchange of animals across zoos.

Planet Money Episode 566: The Zoo Economy

Zoo animals are different than most possessions, because zoos follow a fundamental principle: You can't sell or buy the animals. It's unethical and illegal to put a price tag on an elephant's head. Today on the show: What do you do in a world where you can't use money?

I don’t remember seeing anything on the blog about zoo animal exchange, and it seems some interesting phenomena have arisen in the face of barriers on the use of money as a medium of exchange. For example, it sounds as if there are barter chains that can get started with certain animals for which there is widespread demand (e.g., jellyfish), and that these chains are fostered by zoos’ developing a reputation for “generosity.”

Unfortunately, the story is audio only—a transcript doesn’t seem available yet—but I was glad to have heard it."

I'm reminded of the repugnance aroused by the prospect of art museums selling art works.

An interview in Spanish (with English translation), and one in German

Jordi Benetiz of Capital Magazine interviewed me, and the interview appears on their website, in Spanish, here: Alvin Roth, Nobel de Economía en 2012: “La pobreza está a menudo relacionada con los fallos en los mercados”

There's also an English version here: “Often poverty is related to the failure of markets”

And here's an article in German, which seems to be based on an interview I gave in Lindau, although the picture is from a panel session there:  Der Markt-Designer

Illegal trade in protected species

The NY Times ran a recent story on the crime lab in Ashland Oregon that handles cases related to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES): Animal Traffic

"The lab has been described as “Scotland Yard for animals” and ” ‘CSI’ meets ‘Doctor Dolittle.’ ”
"Wildlife crime has grown to a $19 billion dollar annual global trade, according to a report released last year by the International Fund for Animal Welfare, a conservation nonprofit. The black market in wildlife parts and products is the fourth-largest illegal industry worldwide, behind narcotics, counterfeiting and human trafficking, and it may well outstrip other illicit enterprises in terms of the variety of crimes and the complexities they pose for law enforcement. The wildlife trade encompasses culinary delicacies and Asian medicines, pets and hunting trophies, clothing and jewelry. It takes in commodities such as elephant ivory, rhinoceros horn, bushmeat, the shells of giant tortoises, the pelts of big-game cats. The environmental and social costs of the trade are grave. Wildlife crime is contributing to the erosion of natural resources and the spread of infectious diseases; it is providing robust new revenue streams for criminal syndicates and even terrorists. In a July 2013 executive order enhancing United States government coordination to combat wildlife crime, President Obama deemed the surge in poaching and trafficking an “international crisis” that is “fueling instability and undermining security.”

Competition by intermediaries can drive up prices:

A paper by Ben Edelman and Julian Wright considers how intermediaries can compete with each other for buyers by offering bigger refunds than do their competitors, resulting in higher prices and lower welfare...
