Both the theory and practice of using hedonic regressions to quality adjust inflation estimates are implicitly developed for monopolistic competitive markets. We demonstrate conditions required for consistent OLS estimation of hedonic regression for an oligopoly. To reflect firm heterogeneity,...

Both the theory and practice of using hedonic regressions to remove quality effects in price indexes are implicitly developed for monopolistic competitive markets. In this paper, we theoretically and practically analyze the application of a standard hedonic regression for an oligopoly. In the...

Pollution externalities between polluters should be taken into account in the design of optimal Pigouvian tax. When the externalities are substantial and/or the number of polluters is large, the effluent levies on these firms do not necessarily result in a deadweight loss. Rather, the tax can...
