Firms’ R&D Dilemma: To Undertake Or Not To Undertake R&D

Abstract

It is well known that in most industries a significant proportion of firms do not perform innovative activities. Although empirical studies on the determinants of R&D often have taken this fact into account by considering the dependent variable as a censured one, there is not an explicit theoretical model to explain the zeros. The concern of this letter is to discuss a simple theoretical model where firms simultaneously decide whether to undertake or not R&D activities jointly with the l evel of the R&D investment. We show that a firm performs R&D activities only when its optimal level of R&D expenditure is higher than a threshold. Additionally, we show that both the probability of undertaking R&D activities and the R&D expenditure increase with market power, with the elasticity of demand with respect to quality and with the elasticity of quality with respect to R&D. Finally, from this simple theoretical framework we discuss a suitable econometric model that threats these decisions simultaneously.
