“…Going back to the seminal work by Merton [19], many authors have studied the problem of finding bounds for option prices under incomplete market conditions or an incomplete knowledge of the distribution of the price of the underlying assets (see, e.g., [3,4,5,8,9,15,16,18,21,22,23] and the references therein). Here, we study bounds on the expected payoff of a European call option and its associated risk, given only information on the moments of the underlying asset price at maturity.…”
