Harsanyi Values of Large Economies:
Non-Equivalence to Competitive Equilibria

Sergiu Hart and Andreu Mas-Colell

We consider economies with many agents, and compare the competitive equilibria and the value allocations of the resulting coalitional games. In particular, we provide a (smooth and robust) example where the "value principle" does not hold for the Harsanyi NTU-value: there is a unique competitive equilibrium, which however does not belong to the (nonempty) set of Harsanyi value allocations.
