Firms increasingly rely on markets for technology to acquire innovations developed outside their boundaries, yet acquiring intellectual property rights alone often does not guarantee successful implementation. Many technologies depend on tacit know-how that must be supplied by the provider after the transaction is completed. This paper examines whether common ownership between a technology provider and a potential adopter mitigates this implementation problem. I develop a model in which overlapping institutional investors cause the provider to partially internalize the adopter’s gains from successful implementation, strengthening incentives to transfer tacit know-how. This mechanism operates only when know-how is unverifiable – absent this friction, common ownership leaves matching and outcomes unchanged. Under moral hazard, the model predicts that common ownership increases the likelihood of technology transfer to a given adopter, that this effect is stronger when tacit know-how is more important, and that common ownership improves post-transfer outcomes conditional on adoption. I test these predictions using U.S. patent reassignments between publicly traded firms. Using within-deal variation across competing potential adopters and plausibly exogenous variation from passive index-fund holdings, I show that common ownership increases the likelihood that a firm acquires a technology, particularly when the transferred bundle is more tacit. Common ownership predicts stronger subsequent innovation and higher future firm value, especially when ownership overlap is concentrated among investors with stronger incentives to monitor the provider. These findings show how ownership structure shapes interfirm technology transfer by affecting not only who acquires a technology, but also how much value is created.

Die Wahl Donald Trumps, der Brexit und der Erfolg populistischer Parteien in Europa zeigen tiefsitzende Skepsis gegenüber Experten und Eliten und deren komplexen Erklärungen der politischen und wirtschaftlichen Zusammenhänge. Ökonomen wird vorgeworfen, sich in Detailfragen zu verlieren und ein unrealistisches Menschenbild zu pflegen. Tatsächlich wäre es aber wichtig, die Unabhängigkeit der Ökonomen abzusichern, mehr Transparenz über die Hintergründe ihrer Ergebnisse herzustellen und stärker auf die Relevanz ihrer Forschungsfragen zu achten. Zudem sollten sie mehr Wert auf eine für alle verständliche Kommunikation mit Politik und Medien legen. Umgekehrt sollten letztere sich aber auch ernsthaft mit den ökonomischen Ergebnissen auseinandersetzen.

We analyse the impact that political business cycles and party preferences have on smuggling illegal goods across the US–Mexico border during the years 1980–2004. We find that smuggling is significantly reduced prior to Congressional elections – but only if the incumbent President is Republican.
