This study looks at the efficacy of legislative actions in driving broader changes beyond targeted organizations through shared-personnel-enabled interorganizational spillovers of compliance-oriented related knowledge. Using the context of the Quality Payment Program and leveraging a unique four-year Florida patient claim panel data assembled from three data sources, we employed a Difference-in-Differences analysis for hypotheses testing. Our results demonstrate the existence of interorganizational spillover effects for related knowledge driven by the legislation. We further find spillover effect heterogeneity based on the target performance metrics (distance of related knowledge to focal knowledge) and characteristics of the non-targeted organization (hospital teaching intensity).
