Fifty years ago Arrow [
] introduced contingent commodities and Debreu [
] observed that this reinterpretation of a commodity was enough to apply the existing general equilibrium theory to uncertainty and time. This interpretation of general equilibrium theory is the Arrow-Debreu model. The complete market predicted by this theory is clearly unrealistic, and Radner [
] formulated and proved existence of equilibrium in a multiperiod model with incomplete markets.
In this paper the Radner result is extended. Radner assumed a specific structure of markets, independence of preferences, indifference of preferences, and total and transitive preferences. All of these assumptions are dropped here. We — like Radner — keep assumptions implying compactness.
