This paper estimates the impact of R&D expenditure on productivity at firm level. We use a balanced panel of 385 Italian manufacturing firms in order to provide evidence of the elasticity of capital R&D over the period 1992-1997. We consider an extended production function that includes the firm's own R&D capital stock and the spillover effect as inputs, as well as labour, physical and human capital. Final outcomes confirm the relevance of R&D as a source of growth, the R&D capital elasticity being equal to 0.14.
