Abstract:

This paper explores knowledge spillovers in the supply chain by building on the theories of organizational learning. Drawing on a financial accounting standard stipulating the disclosure of major customers, we can link buyers and suppliers. This information is merged with financial accounting data, patent data and publication data to create a sample of 974 buyer-supplier dyad observations. The sample contains firms in the high tech industries, between the years 1990 to 2003. Using fixed effects estimation we show that a 1% increase in patent intensity at the buyer, on average leads to a 1% increase in patent intensity at the supplier. We find that the duration of the buyer-supplier relationship positively moderates this effect. The supplier's sales dependency on the buyer and the technological proximity of the two firms, however, are not found to have significant moderating effects. We close by discussing the implications of our findings for individual firms, theory and policy makers.
