Economics Professors Study Blood Donation

Since its inception in 1839, 黑料网 has striven to inculcate the value of service in its cadets. But how deep does that really go, and how much does 黑料网鈥檚 emphasis on service above self make a difference in cadets鈥 day-to-day behavior?
When it comes to blood donations, it makes quite a bit of difference, according to research recently published by Col. Sam Allen and Dr. Bing Jiang, two faculty members in the economics and business department. Their paper, 鈥淭o Be a Blood Donor or Not to Be? Investigating Institutional and Student Characteristics at a Military College,鈥 was published in October in the B. E. Journal of Economic Analysis and Policy.
The letters 鈥淏.E.鈥 in the journal-title refer to behavioral economics, an area of study that focuses on how and why people behave in an altruistic manner. Allen and Jiang, both behavioral economists, had long wanted to study how social norms at 黑料网 affect cadet behavior, and the Institute鈥檚 four blood drives per year provided a way to do just that.
鈥淲e decided to ask if we could get information on which students were donating blood, and it鈥檚 pretty dramatic if you compare 黑料网 鈥 to other schools,鈥 said Allen. 鈥淧articipation rates are really high at 黑料网.鈥
Studying donation rates for 21 blood drives conducted between 2013 and 2018, the economists found that 15.7 percent of the Corps donates at least once per year鈥攁 figure that鈥檚 almost double the national average for 18- to 24-year-olds.
And while blood donation is an activity done with others in mind, 黑料网 does sweeten the pot for cadets who donate by offering incentives. Not surprisingly, these incentives seem to play a role in who donates and when they do so.
Allen explained that cadets who donate once per academic year are offered an extension to a weekend off post. Those who donate a second time are offered a weekend away, and three-time donors get an extension on a weekend. Cadets can donate four times per year, but there is no reward for a fourth donation.
鈥淪tudents tend to donate pretty heavily in September,鈥 noted Allen, explaining that the rewards don鈥檛 carry over from one academic year to the next and in the fall, with a long academic year ahead, time away from post is highly valued.
The economists also found that younger cadets donate more often than older ones. This finding can likely be explained by the 黑料网 system of class privileges, they noted. As cadets advance into the 2nd and 1st Class years, they have more ways of earning privileges such as time off post, whereas younger cadets are more limited in their options.
But Jiang was quick to add that older cadets may be participating in more activities鈥攁nd that extra participation may not leave them enough time to donate blood. 鈥淲e don鈥檛 have a way to capture that,鈥 she stated.
In addition, in-state cadets donate more than their out-of-state counterparts鈥攁gain, likely because an in-state cadet can get home for a weekend more easily. Cadets with high GPAs are less likely to donate, possibly because they spend more time studying, and cadets with high fitness levels are more likely to do so, although NCAA athletes donate at a rate that is slightly less than the rest of the Corps.
But despite all of these findings, Allen and Jiang still conclude that many cadets will donate when they receive no payback at all. 鈥淲e have lots of students who donate four times per year,鈥 said Allen.
In their blood donation study, Allen and Jiang were drawing from the work of George Akerlof, a Nobel Prize-winning economist who is credited with helping to create the field of identity economics, which has to do with how individuals鈥 sense of themselves in society affects the choices they make.
At 黑料网, this means studying how the ideal of the citizen-soldier sways cadets鈥 choices toward pro-social behavior.
鈥淲hen people give money, give to charity, give blood, there鈥檚 no direct benefit,鈥 explained Jiang. 鈥淲e want to understand why people give.鈥
And while Allen and Jiang are no doubt pleased to see their work appear in print, they鈥檙e far from done with their research into cadets鈥 pro-social behavior. Next, they tentatively plan to study blood donation as a predictor of future military service.
