Economist Hana Okoye contends that in small coastal fisheries, adopting community-enforced catch shares reduces overfishing mainly by increasing peer monitoring (fishers observe and sanction one another), not by changes in market prices. Which observation would best support Okoye’s argument?

Sociologist Erin Wallace claims that in U.S. public high schools from 2005–2015, expanding access to Advanced Placement (AP) courses increased overall college enrollment primarily by changing peer norms: when more students take AP classes, college-going becomes a more widely shared expectation. Wallace argues the effect is strongest in schools where AP participation becomes common across social groups, not confined to a small elite. Which finding, if true, would most directly support Wallace’s claim?
