Efficient Mixed Clubs: Nonlinear‐Pricing Equilibria With Entrepreneurial Managers

Scotchmer and Wooders show that efficient clubs are homogeneous when consumers are divisible in Berglas's anonymous crowding model. However, if consumers are not divisible or if clubs have multiple facilities with economies of scope, mixed clubs are efficient. In such a model, we consider clubs with multiple membership policies for different types of consumers, and show the existence and efficiency of equilibrium with nonlinear policies. We employ entrepreneurial equilibrium, all equilibrium concept with profit‐seeking entrepreneurs. Our theorem can be regarded as showing the existence of a core allocation that satisfies envy‐free property in the absence of non‐anonymous crowding effects.
