We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

Firm agglomeration is positively correlated with productivity, and it exhibits significant heterogeneity across industries. Yet, the connection between agglomeration and corporate investment remains underexplored. We develop a model of information sharing which predicts that knowledge-intensive...

Die deutsche Autoindustrie kann auf ein goldenes Jahrzehnt zurückblicken. Zwischen den Jahren 2008 und 2018 erzielten die Unternehmen einen Absatzrekord nach dem anderen. Der Haupttreiber dieser Entwicklung war das starke Wachstum des chinesischen Marktes, von dem die deutschen Hersteller und...

Objective: The aim of this article is to investigate the impact of vertical R&D cooperation on market performance of firms. Specifically, we explore the impact of vertical R&D cooperation on firms’ process innovation, outputs, market prices, and economic profits. Research Design & Methods: We...

This study explicitly takes into account that the decision to enter into a cooperative R&D relationship is related to the antecedent decision to carry out R&D. This calls for a methodological approach that, at the same time, allows the joint analysis of the determinants of the two decisions and...

Patent race models assume that an innovator wins the only patent covering a product. But when technologies are complex, this property right is defective: ownership of a product's technology is shared, not exclusive. In that case I show that if patent standards are low, firms build "thickets" of...

Technology lock-in advocates argue that governments should step in to coordinate technology adoption decisions. Due to the presence of network effects, advocates warn that consumers may fail to adopt the best technology, thus missing out on potential benefits. Even worse, consumers may split,...

We find that the effects of parent firm R & D on plant-level productivity are diminished by both the geographic and technological distance between the research lab and the plants, that productivity appears to depend on R & D per plant rather than on the total amount, and that spillovers from...
