Fewer Helmets, Higher Healthcare Costs

We’ve written before about an unintended consequences of state repeals of motorcycle helmet laws: more organs available for transplant.  Here’s one more consequence, from Michigan, which stopped requiring helmets last year:

State legislators changed the law last year so that only riders younger than 21 must wear helmets. The average insurance payment on a motorcycle injury claim was $5,410 in the two years before the law was changed, and $7,257 after it was changed – an increase of 34 percent, the study by the Highway Loss Data Institute found.

After adjusting for the age and type of motorcycle, rider age, gender, marital status, weather and other factors, the actual increase was about 22 percent relative to a group of four comparative states, Illinois, Indiana, Ohio and Wisconsin, the study found.

“The cost per injury claim is significantly higher after the law changed than before, which is consistent with other research that shows riding without a helmet leads to more head injuries,” David Zuby, chief research officer for the data institute and an affiliated organization, the Insurance Institute for Highway Safety, said.

An Easy Way to Cut Down on Pill Suicides?

Ezekiel Emanuel, who’s popped up in our blog and podcasts, writes in the Times about a simple way to reduce suicides:

We need to make it harder to buy pills in bottles of 50 or 100 that can be easily dumped out and swallowed. We should not be selling big bottles of Tylenol and other drugs that are typically implicated in overdoses, like prescription painkillers and Valium-type drugs, called benzodiazepines. Pills should be packaged in blister packs of 16 or 25. Anyone who wanted 50 would have to buy numerous blister packages and sit down and push out the pills one by one. Turns out you really, really have to want to commit suicide to push out 50 pills. And most people are not that committed.

The Persistence of Financial Illiteracy

Annamaria Lusardi, the doyenne of financial (il)literacy reseach (she has appeared on this blog and on Freakonomics Radio), is back with more depressing news.  The Wall Street Journal summarizes:

In fact, Americans’ grasp of concepts such as investment risk and inflation has weakened since the recovery began in mid-2009. Research released last week shows that on a five-question test (take the test here), respondents did worse in 2012 than in 2009. The average number of correct answers fell to 2.9 in 2012 from 3.0 on the test in 2009.

Unfortunately, the research indicates that most people aren’t aware of their own shortcomings:

Although many respondents were short on financial education, they didn’t lack confidence about managing their books. Researchers said they found “a disconnect between self-perceptions and actions in day-to-day financial matters.” Many people who gave themselves high marks for managing their finances also were using non-bank borrowing methods, such as payday loans, or had overdrawn their checking accounts.

On the plus side, more respondents indicated they were able to cover their monthly expenses (40 percent as compared to 36 percent in 2009).



Is Paying for Blood a Good Idea After All?

An article in Science by Nicola Lacetera, Mario Macis, and Robert Slonim summarizes their research on economic incentives and blood donation (abstract; PDF). Contrary to previous studies, the researchers found that various incentives, from gift cards to a day off, increased blood donation: 

Overall, 18 of the 19 distinct incentive items offered in observational and field experimental studies increased blood donations, and the effects were larger for items of higher monetary value; only one reward offer, a free cholesterol test, had no effect. When data were available (for 15 of the items), no effect on blood safety was detected. Finally, although temporary rewards might affect long-term motivations, no post intervention effects on donations were found, including any negative effects deriving from potential motivation loss.
