This paper examines the trends in geographic localization of knowledge spillovers via patent citations, extracting multiple cohorts of new sample US patents from the period of 1976-2015. Despite accelerating globalization and widespread perception of the "death of distance," our matched-sample...

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...

We analyze cross-country trends in technological progress over the period of 1980-2011 by examining citations data from almost 4 million utility patents granted by the US Patent and Trademark Office (USPTO). Our estimation results on patent quality and distance to the knowledge frontier reveal...

We examine the incentives for experimentation in the context of innovation and market competition. A monopolist chooses whether to sell early-stage product or perform costly scale-up R&D. Early market participation facilitates learning about demand but invites knowledge spillovers and...

We introduce knowledge spillovers in a model of innovation competition à la Federico et al. (2017) and Denicolò and Polo (2018), which otherwise features horizontal mergers that harm innovation due to the business stealing effect. With knowledge spillovers, competition discourages investment...
