The level of CSR determines the weight a firm puts on consumer surplus in its objective function before it decides upon supply. We show that the more efficient firm chooses a higher CSR level, reinforcing its dominant position. If there are sufficiently large fixed costs of CSR, only the more efficient firm will engage in CSR.engcorporate social responsibilitycournot duopolyasymmetric costsheterogenous firms650articleurn:nbn:de:bvb:473-irb-539411
