First, we relax the strong technical assumptions he imposed on preferences and consumer types. Second, we extend the result beyond the monopolistic market structure to generalized oligopoly settings with entry. We also analyse applications to several quite different settings: credit markets, automobile industry, research grants, the regulation of a monopolist with unknown demand and cost functions, and involuntary unemployment in the labor market.34 p.DigitalPortuguêsworking paperMultidimensional screeningexclusionregulation of a monopolyinvoluntary unemploymentBEWP 089/2010
