Modern corporate governance codes include clauses requiring the disclosure of managerial compensation. Such codes have been installed to protect shareholders' interests. In this paper, we explore the impact of such disclosure on consumer welfare. We consider two-stage delegation games in which owner-shareholders negotiate about compensation with their managers in the game's first stage. At the end of the first stage, the managerial compensation contract outcomes of the bargaining process are publicly announced. In the second stage, Cournot competition evolves. We prove that sales delegation generates equilibria radically different from relative performance delegation. Using classical Cournot as the benchmark, contractual bargaining over sales compensation gives tougher product market competition - and hence higher consumer surplus. The opposite holds true for relative performance delegation. Then, cartel behavior is promoted, reducing consumer surplus.
