Estimating the Effects of Interventions That are Deployed in Many Places: Place-Randomized Trials

Estimating the Effects of Interventions that are Deployed in Many Places: Place-Randomized Trials
Place-randomized trials have been mounted in a variety of countries to estimate the relative effects of interventions that are intended to ameliorate problems or improve conditions in organizations and geopolitical jurisdictions. This article presents studies in which villages, police hot spots, housing developments, hospital units, schools, and other entities are the units of random allocation.
