Abstract

The regulation of monopolistic firms has been widely investigated in the economic literature. Particular emphasis has been placed on the relationship between the regulated monopolist and the regulator. The present work deals with problems that may arise from the presence of several regulators. If regulators have different objective functions, inefficiency is likely to arise. A theoretical model with two regulators, one monopolistic firm and a renewable natural resource is presented. In this set up the level of demand relative to the sustainable use of the water resource plays a major role. The main result is the characterization of the cases in which the outcome of the regulation actually differs between the integrated-regulator and the separate-regulator scenarios. We find that the main determinants of the equilibrium are the level of demand and the marginal environmental damage. The equilibria obtained are analyzed in terms of price, environmental tax levels, and in terms of welfare distribution among the components of the regulator(s)' objective function.
