Innovation processes within corporations increasingly tap into international technology sources, yet little is known about the relative contribution of different types of innovation channels. We investigate the effectiveness of different types of international technology sourcing activities...

Aghion, Van Reenen and Zingales (2013) find that institutional ownership causes an increase in innovation as measured by citation-weighted patent counts. To identify a causal effect, they use membership in the S&P 500 as an instrument for institutional ownership in a panel regression. We first...

How much does US-based R&D benefit other countries and through what mechanisms? We test the 'technology sourcing' hypothesis that foreign research labs located on US soil tap into US R&D spillovers and improve home country productivity. Using panels of UK and US firms matched to patent data we...

We examine the home bias of knowledge spillovers (the idea that knowledge spreads more slowly over international boundaries than within them) as measured by the speed of patent citations. We present econometric evidence that the geographical localization of knowledge spillovers has fallen over...

Recent research suggests that much of the cross-firm variation in measured productivity is due to differences in use of advanced management practices. Many of these practices - including monitoring, goal setting, and the use of incentives - are mediated through employee decision-making and...

We examine the “home bias” of knowledge spillovers (the idea that knowledge spreads more slowly over international boundaries than within them) as mea- sured by the speed of patent citations. We present econometric evidence that the geographical localization of knowledge spillovers has...
