What are the dynamics of R&D investment when firms agglomerate in environments with weak intellectual property rights protection? Specifically, do foreign and domestic firms present equal opportunities for free riding by domestic firms in such environments? We examine the impact on local firms' R&D investment from knowledge spillovers originating from co‐located foreign and domestic firms within and across industries. Building on fieldwork in I ndia, we predict free riding by local firms on nearby foreign and local firms. Furthermore, we expect local firms to free ride more from other local firms within their industry and from foreign firms across industries. Analyzing a sample of 3,475 R&D lab investment decisions during 2003–2010 in I ndia, we find that local firms free ride from other local firms both within and across industries .
