Organ Donation Supply and Demand

My wife is helping with a local drive to get people to register to donate organs. We thought that, as a cancer survivor, she herself would not be allowed to register. Wrong. Anyone under age 85 can register, so long as their cancer is not active and they do not have a systemic infection of any kind.

The doctor who informed us says this increases the potential supply of transplantable organs. If the demand is high enough, and the patients sick enough, the doctors will choose to use a donated organ even if the transplantation risk from the particular organ is substantial. Thus, while fortunately the price system is not used explicitly in the transplantable organ market, the choice to allow more people to register and to compare the demand to the increased supply suggests economics is currently present in this market.



We Are Shocked — Shocked! — to Learn that College Football Coaches Exhibit a Conflict of Interest When Rating Teams

File under “Not Surprising But Still Interesting.” A new working paper by Matthew Kotchen and Matthew Potoski makes these claims:

Using individual coach ballots between 2005 and 2010, we find that coaches distort their rankings to reflect their own team’s reputation and financial interests. On average, coaches rank teams from their own athletic conference nearly a full position more favorably and boost their own team’s ranking more than two full positions. Coaches also rank teams they defeated more favorably, thereby making their own team look better. When it comes to ranking teams contending for one of the high-profile Bowl Championship Series (BCS) games, coaches favor those teams that generate higher financial payoffs for their own team. Reflecting the structure of payoff disbursements, coaches from non-BCS conferences band together, while those from BCS conferences more narrowly favor teams in their own conference. Among all coaches an additional payoff between $3.3 and $5 million induces a more favorable ranking of one position. Moreover, for each increase in a contending team’s payoff equal to 10 percent of a coach’s football budget, coaches respond with more favorable rankings of half a position, and this effect is more than twice as large when coaches rank teams outside the top 10.

“Football Freakonomics”: How Much Do Injuries Hurt?

The following is a cross-post from NFL.com, where we’ve recently launched a Football Freakonomics Project.

It doesn’t take a genius to argue that injuries can have a massive effect on an NFL team’s fortunes. This season, we may be living through the most heightened example in history of that fact. The Indianapolis Colts, with Peyton Manning sidelined since Week 1 with a neck injury, currently stand winless at 0-12. Over the previous five seasons with Manning in charge, the Colts have gone 61-19 during the regular season.

How can the absence of one player, even a star quarterback, have such an impact? As Aaron Schatz of Football Outsiders contends in the latest episode of Football Freakonomics: “Not only were they built around him offensively, but the defense was generally built around them getting the lead and then having defensive ends just tee off on the opposing QB while the other team has to pass to try to catch up.”

The Manning-less Colts are losing off the field too – attendance is down, Manning jersey sales are down, and some Colts fans have jumped on the “Suck for Luck” campaign, figuring that if the Colts are going to be bad they might as well be bad enough to snare Andrew Luck with the top pick in the draft.

Answer to Our Nudge Photo Contest

The results are in from the nudge photo contest we posted on Monday. Thirty-six out of 103 responses got it exactly right: to stop folks from urinating on the wall. Many also wrote that it was to prevent grafitti, so close but not (as I’ve been told) the exact motivation.

The first to answer correctly was, Skyjo, whose response was third overall.

Of the 36 correct answers, we randomly chose comment #63 by ann, “So that people won’t urinate on the wall as a sign of respect.”

Nudges aren’t just for humans. Here is a photo, also from Jan Chipchase, of a similar nudge with the same exact goal of reducing public urination. This time the target is dogs, not humans.
