چکیده
We study a stochastic dynamic game of process innovation in which firms can initiate and terminate R&D efforts and production at different times. We discern the impact of knowledge spillovers on the investments in existing markets, as well as on the likely structure of newly forming markets, for all possible asymmetries between firms. While an increase in spillovers may improve the likelihood of a competitive market, it may at the same time reduce the level to which a technology is developed. We show that the relation between spillovers, R&D efforts, and surpluses depends on relative as well as absolute efficiency of firms. High spillovers are not necessarily pro-competitive as they can make it harder for the laggard to catch up with the technology leader.

متن کاملThe role of spillovers in research and development expenditure in Australian industries
Using administrative data from firms in Australia that conduct research and development (R&D), we examine how R&D activity of other firms and public institutions affect a firm’s own R&D expenditure. We distinguish between the impact of peers, suppliers and clients. We examine whether geographical proximity and industrial clustering affect R&D spillovers. Overall, we detect positive effects on R...

Innovation, Demand and Knowledge Spillovers: Theory and Evidence from European Regions
The Importance of innovation for the economic performance of industrialized countries has been largely stressed recently by the theoretical and empirical literature. Very few studies have carefully considered the determinants of European innovation, the productivity of its R&D and the existence of knowledge spillovers across regional boundaries. Here we develop a model which, emphasizing “the d...
