Exploiting the available degrees of freedom in coagglomeration patterns, we estimate the industry-speci c benefi ts of sharing labor needs and supply links with local rms. On aggregate, coagglomeration patterns of services are at least as strongly driven by input-output linkages as those of manufacturing, whereas labor linkages are much more potent drivers of coagglomeration in services than in manufacturing. Moreover, the degree to which labor and input-output linkages are reflected in an industry's coagglomeration patterns is relevant for predicting patterns of city-industry employment growth.en-USResearch Paper or Report2020-12-16
