(Margin Requirements) This exercise models a simple example of a margin requirement, which is a type of collateral constraint. For each j ∈ {1, . . , J}, let V j = (Sj, Dj) for some asset Dj and spot price Sj > 0. The first asset is a unit discount bond (D1 = 1), while the remaining assets are risky. The margin requirement is that the combined value of all long risky-asset positions plus the (possibly negative) value of the discount-bond position must be at least equal to half the total value of long risky-asset positions plus one and a half times the amount raised by short selling risky assets.

The market may or may not allow default-free borrowing and lending, meaning that X(1) may or may not include the unit discount bond payoff 1. If 1 X(1), then the corresponding risk-free discount factor, denoted ρ, is the present value of 1 and is positive since X is arbitrage-free. On the linear space X(1), we define the inner product The demeaned version of a random variable z is denoted . More precisely, this means , but as is common in probability theory, we identify a scalar α with the random variable that is identically equal to α.

If S = Fρ, then each one of the three contracts is a synthetic contract in the other two. 18. Suppose the arbitrage-free market X is implemented by spot trading in the J assets forming the rows of the J × K matrix . That means X = X (V), where V(1) = D and V(0) = S for a column vector whose jth entry is the spot price of asset Dj. If Dk = θ'D for some replicating portfolio θ with θ k = 0, then Sk = θ'S. The analogous discussion applies to a forward market in the J assets. The contracts V 1 , . .
