We study general discrete-types multidimensional screening without any noticeable restrictions on valuations, using instead epsilon-relaxation of the incentivecompatibility constraints. Any active (becoming equality) constraint can be perceived as "envy" arc from one type to another, so the set...

Price discrimination is an extensively studied subject in monopoly behavior. Increasing profits, covering fixed cost and reducing distortions are reasons to sell a homogenous good at different prices. Price discrimination is however present also in oligopolistic markets. This paper is going to...

The demand for organic fresh fruits and vegetable continues to grow at a rate far higher than the rest of the produce industry. The cost of meeting organic certification standards, however, has meant that supply has been slow to adjust. With limited supply, we hypothesize that organic suppliers...
