Abstract: We study the convexity property of the set of arbitrage-free prices for a multi-period financial exchange economy. We provide sufficient conditions for the set of arbitrage-free prices to be a convex cone, which includes 2-date model. Further we show that a financial exchange economy with the set of arbitrage-free prices neither convex nor cone can be equivalent to a financial exchange economy with the convex cone set of arbitrage-free prices.
