A valuation process for a payoff is then … valuing by absence of arbitrage alone. We show that this always yields put-call parity, although put and call values …

We consider fundamental questions of arbitrage pricing arising when the uncertainty model incorporates volatility … uncertainty. With a standard probabilistic model, essential equivalence between the absence of arbitrage and the existence of an … martingale measure sets, in a dynamic trading framework under absence of prior depending arbitrage.

We further deduce a pricing formula for European options written on the precipitation swap and obtain the … minimal variance hedging portfolio in the underlying weather market. In the second part of the paper, we provide a … formula for the associated information premium and investigate minimal variance hedging of precipitation derivatives under …
