Existing models of R&D are not easily reconciled with four observable aspects of R&D: initial technologies (“ideas”) need to be developed further, only a minority of initial ideas is successfully brought to the market, production and process innovations take place simultaneously (whereby,...

We present a continuous-time generalization of the seminal R&D model of d’Aspremont and Jacquemin (American Economic Review, Vol. 78, No. 5) to examine the trade-off between the benefits of allowing firms to cooperate in R&D and the corresponding increased potential for product market...

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...
