math modeling 9. The following simple model is intended to represent the dynamics of supply and demand. Let P denote the selling price of a certain product and Q the quantity of this product being produced. The supply curve Q = f(P) tells how much should be produced at a given price to maximize profit. The demand curve P = g(Q) tells what price buyers should pay given a certain level of production in order to maximize their utility. (a)...

Suppose that you have a stock in the one-period binomial model with fixed u, d,and r suchthat 0< d <1 + r < u. Suppose that there are positive numbers p1and q1such that p1,q1<1, p1+q1= 1, and (1 +r)S0=p1S1(H) +q1S1(T). Show that p1= ̃p and q1= ̃q .Hint: You know that the risk-neutral probabilities satisfy these equations as well.
