Great paper, but I have an issue with the student incentives. Free tuition might not be of interest to those underperforming in community colleges, so the likely result is that, when combined with teacher incentives, there is no real change. I would have split the student incentives into two treated groups: the first being allowed to go on a 3-day trip to some (exotic!) foreign location and the other being the prestige of a new console (a PS6 or the like!). These oppurtunities appeal more to young students nowadays, although I'm not american, so perhaps there are other more culturally engaging incentives out there! My experience as an intern in a stockbroker firm tells me that incentives work best when they're double-edged and benefit both parties, but perhaps less resources would be used up if they were one-sided.🤭
