Abstract:
In this paper, we measure the effect of internal R&D and various spillover concepts on productivity growth, using a database for France that covers the period 1978-92. Three spillover concepts are distinguished: rent spillovers related to investment goods; rent spillovers related to intermediate goods; pure knowledge spillovers. When production is measured by gross output, all three spillover concepts yield positive and statistically significant coefficients. Each concept has a measurable effect on technological progress at the sectoral level. Copyright 1997 by Taylor and Francis Group
