The Gravity of Knowledge

Working Paper: CEPR ID: DP7553

Authors: Wolfgang Keller; Stephen R. Yeaple

Abstract: How large are spatial barriers to transferring knowledge? We analyze the international operations of multinational firms to answer this fundamental question. In our model firms can transfer bits of knowledge to their foreign a¢ liates in either embodied (traded intermediates) or disembodied form (direct communication). Knowledge transfer costs interact with the knowledge intensity of production to determine the geographic structure of multinationals' input sourcing as well as its competitiveness in foreign markets. The model shows how data on observable trade costs and features of multinationals' global operations reveal the size and nature of knowledge transfer costs. Our empirical analysis confirms the model's predictions using firm-level data, quantifies the aggregate implications of the model for the structure of multinationals' operations, and demonstrates that transfer costs shape the knowledge content of intra-firm trade flows.
