Identifying technology spillovers and product market rivalry
Bloom, Nick; Schankerman, Mark; Van Reenen, John - London School of Economics (LSE) - 2005
Government policies to support R&D are predicated on empirical evidence of R&D "spillovers" between firms. But there … are two countervailing R&D spillovers: positive effects from technology spillovers and negative effects from business … stealing by product market rivals. We develop a general framework showing that technology and product market spillovers have …

The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years …. A central problem in the literature is that firm performance is affected by two countervailing "spillovers" : a positive … effect from technology (knowledge) spillovers and a negative business stealing effects from product market rivals.

Peer effects in science: evidence from the dismissal of scientists in Nazi Germany
Waldinger, Fabian - London School of Economics (LSE) - 2009
This paper analyzes peer effects among university scientists. Specifically, it investigates whether the number of peers and their average quality affects the productivity of researchers in physics, chemistry, and mathematics. The usual endogeneity problems related to estimating peer effects are...

Recovering the sunk costs of R&D: the moulds industry case
Santos, Carlos Daniel - London School of Economics (LSE) - 2009
Sunk costs for R&D are an important determinant of the level of innovation in the economy. In this paper I recover them using a Markov equilibrium framework. The contribution is twofold. First, a model of industry dynamics which accounts for selection into R&D, capital accumulation and...

A trapped-factors model of innovation
Bloom, Nicholas; Romer, Paul M.; Terry, Stephen J.; Van … - London School of Economics (LSE) - 2013
We explain a counterintuitive empirical finding: Firms facing more import competition do more innovation. In our model, factors are trapped inside a firm. An increase in import competition encourages a firm to innovate by reducing the opportunity cost of inputs. Without trapped factors, trade...

Technology, information and the decentralization of the firm
Acemoglu, Daron; Aghion, Philippe; Lelarge, Claire; Van … - London School of Economics (LSE) - 2006
This paper develops a framework to analyze the relationship between the diffusion of new technologies and the decentralization decisions of firms. Centralized control relies on the information of the principal, which we equate with publicly available information. Decentralized control, on the...

Strategic patenting and software innovation
Noel, Michael; Schankerman, Mark - London School of Economics (LSE) - 2006
model that incorporates both effects, together with R&D spillovers. Using panel data for the period 1980-99, we find … evidence that both strategic patenting and R&D spillovers strongly affect innovation and market value of software firms. …
