Abstract

Private state-verification is introduced in a two-period economy with spot markets in both periods and complete futures markets for contingent delivery in the second period. Existence of equilibrium is established, under standard assumptions. The equilibrium allocation is shown to be generically efficient if the number of states is not greater than the number of goods.
