Constrained Pseudo-Market Equilibrium

We propose a pseudo-market solution to resource allocation problems subject constraints. Our treatment of constraints is general: including bihierarchical due considerations diversity in school choice, or scheduling course allocation; and other forms needed model, for example, the market roommates, combinatorial assignment problems, knapsack Constraints give rise pecuniary externalities, which are internalized via prices. Agents pay extent that their purchases affect value relevant at equilibrium The result constrained-efficient market-equilibrium outcome. outcome fair treat agents symmetrically.
