To test whether students’ educational investments are affected by peer pressure, researchers offered high school students the opportunity to sign up for free access to an online SAT preparatory course. Some students were told that their decision to sign up would be public, and others were told that their decision would be kept private. In non-honors classes, sign-up rates were lower for students who were told that their decision would be public. In honors classes, sign-up rates were not affected.

Researchers partnered with several agencies of the Government of Punjab, Pakistan, to evaluate the impact of giving procurement officers more autonomy, compared to financial rewards, on public procurement performance. Shifting authority away from supervisors and towards procurement officers improved performance, particularly when supervisors were more inefficient or corrupt. In contrast, financial rewards for officers did not improve performance when their supervisors were inefficient or corrupt.
