In a financial economy with asymmetric information and incomplete markets, we study how agents, having no model of how equilibrium prices are determined, may still refine their information by eliminating sequentially ¡°arbitrage state(s)¡±, namely, the state(s) which would grant the agent an arbitrage, if realizable.
