Multi-dimensional screening:: A user's guide

Abstract Multi-dimensional screening models have many potential applications but economists have so far been hindered by the considerable technical difficulties involved in their resolution. This paper studies the simplest formulation of the general screening model, and we provide a complete solution to this case. We then show how this model can be applied to multi-product nonlinear pricing and to multi-product monopoly regulation. Finally, we discuss how the model has been applied to other economic situations of interest, including auction design and optimal taxation.
