WebIn this paper, we develop an optimal matching strategy for clustered observational studies. Contrary to intuition and common practice, which first matches clusters and then matches units within matched clusters, our strategy does the opposite: it first matches pairs of units across all possible combinations of treated and control clusters, and, once all the possible …
