Abstract

We examine a simple hidden information economy with a single agent, multiple identical firms, and two goods. The agent’s states are unknown to the firms. The game unfolds in two stages: in the first stage, firms offer a menu of allocations, and in the second stage, the agent selects her preferred allocation from the offered allocations. We show that, in almost all cases, the constrained efficient allocation cannot be implemented by a subgame perfect equilibrium in the game.
