Strategic patenting is widely believed to raise the costs of innovating, especially in industries characterised by cumulative innovation. This paper studies the effects of strategic patenting on R&D, patenting and market value in the computer software industry. We focus on two key aspects:...

We use futures instead of forward rates to study the complete maturity spectrum of the forward premium puzzle from two days to six months. At short maturities, the slope coefficient is positive, but it turns negative as the maturity increases to the monthly level. Futures data allow us to...

The recent emergence in the industrial organization literature of a wave of studies identifying small firms as being at least as innovative as their larger counterparts poses something of a paradox. Where do small firms get their knowledge generating inputs? The purpose of this paper is to link...

In this paper we consider the case for subsidies towards firms which generate R&D spillovers in open economies. We show that in the presence of strategic behaviour by firms many expected results are overturned. Local R&D spillovers to other domestic firms may justify an R&D tax rather than a...

This paper aims at assessing the impact of R&D spillovers on firms’ economic performance as measured by productivity growth. The construction of R&D spillovers is based on Jaffe’s methodology (1986, 1988), which associates econometrics and data analysis. The main objective of the paper is to...

This paper examines the rationale for multilateral agreements to limit investment subsidies. The welfare ranking of symmetric multilateral subsidy games is shown to depend on whether or not investment levels are "friendly", raising rival profits in total, and/or strategic complements, raising...

Empirical evidence strongly suggests that R&D increases a firm’s ‘absorptive capacity’ (its ability to absorb spillovers from other firms) as well as contributing directly to profitability. We explore the theoretical implications of this. We specify a general model of the absorptive...

This paper examines the free-market and socially-optimal outcomes in a dynamic oligopoly model with R&D spillovers. First-best optimal subsidies to R&D are higher when firms play strategically against each other, but lower when they cooperate on R&D (at least with high spillovers) and when they...

We simultaneously assess the contributions to productivity of three sources of research and development spillovers: geographic, technology and product–market proximity. To do this, we construct a new measure of geographic proximity that is based on the distribution of a firm’s inventor...

We analyse strategic interaction in R&D internationalization decisions by two multinational firms competing both abroad and in their home markets and examine different incentives for foreign R&D faced by technology leaders and technology laggards. The model takes into account the impact of local...
