This paper examines the trends in geographic localization of knowledge spillovers via patent citations, considering US patents from the period of 1976-2015. Despite accelerating globalization and widespread perception of the \death of distance," our multi-cohort matched-sample study reveals signi cant and growing localization e ects of knowledge spillovers at both intra- and international levels after the 1980s. Increased localization e ects have been accompanied by greater heterogeneity across states and industries.
