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 Betriebe der Möbelindustrie in Ostdeutschland erreichten beachtliche Restrukturierungsfortschritte. Der Umsatz wurde von 1995 bis 1999 um rund ein Drittel, darunter auch im Ausland, ausgeweitet, der Beschäftigungsabbau ist gestoppt und die Produktivität ist deutlich angehoben worden. Dennoch bestehen zum Teil noch deutliche Lücken zu Betrieben in Westdeutschland, u. a. in der Arbeitsproduktivität.

Am Ende des Jahres 2000 hat sich das Konjunkturbild eingetrübt. In Deutschland und Europa ist der Zuwachs der gesamtwirtschaftlichen Produktion schwächer geworden. Die Stimmung bei Produzenten und Verbrauchern hat sich vor allem wegen der Belastungen durch den hohen Ölpreis verschlechtert. So war auch die Sachlage, als die Wirtschaftsforschungsinstitute im Herbst den Tempoverlust der Konjunktur für 2001 bezifferten. Danach griff eine neue Welle von Konjunkturpessimismus um sich. Das IWH hat sich dem nicht angeschlossen. Denn neben den Anzeichen für Verschlechterungen gibt es auch welche für Besserungen: Der Ölpreis geht wohl schneller als erwartet zurück, der Euro scheint sich zu stabilisieren. Beides nimmt Druck von den Preisen....

Many countries and regions remain below the level of economic activity of the world’s most advanced economies. Some countries form growth clubs, some are stuck in the middle-income trap, and some stay on a very low level of economic activity. Although this situation is well documented on the country level, there is less evidence at the sub-national level within countries. We estimate county-level capital stocks and price indices and provide a comprehensive county-level data set for Germany. We find no evidence of convergence across all counties even if we condition on important drivers of long-term growth such as physical and human capital accumulation. Instead, we identify five convergence clubs, using endogenous clustering. We analyze differences in growth paths and describe the identified clusters based on variations in contributions of capital, labor, and total factor productivity to economic growth. Additionally, we examine the role of migration for regional development and find that net migration has in particular contributed to growth in richer regions.
