摘要：We use a laboratory experiment to study the link between cooperative research and development (RD) in clean technology and collusion in a downstream product market in the presence of a time‐consistent emissions tax. Such a tax creates additional interconnections between firms, in addition to the standard technological spillovers. Our results show a link between RD cooperation and market collusion under symmetric RD spillovers in a duopoly, but when the spillovers are asymmetric, RD cooperation does not necessarily result in collusion. With symmetric spillovers, the link between RD cooperation and collusion remains even in three‐ and four‐firm industries. (JEL C90, L5, O30, Q55)
