Draw the payoff function of the log-contract.

Log-contract The payoff of the log-contract on an underlying asset S is DT = – ln(ST / F0), where F0 is the forward price of S for maturity T.

(a) Draw the payoff function of the log-contract.

(b) Find the fair value D0 of the log-contract in the lognormal model as a function of r, σ and T.

(c)  Imagine that, for a given maturity T, we know the prices of an infinite number of European calls and puts struck along a continuum between 0 and infinity. Consider a portfolio which is:

(i) long a quantity dK / K² of puts struck at K <>₀;

(ii) long a quantity dK / K² of calls struck at K > F₀.
