The Arrow-Debreu model is extended to include a sequential market model with financial markets. This is done by dropping the contingent contracts from the Arrow-Debreu model, leaving only a sequence of spot markets for commodities. The resulting market structure is inefficient. Efficiency is restored with a sequence of stock markets and option markets. In addition, consumers are shown to be unanimous in wanting each firm to maximize the price of its common stock.
