1. Compare Eq. (8.16) to the CAPM result for expected returns, to relate u to rQ. Impose the requirement that E{u} = 1 to determine u exactly as a function of rQ.
2. Using the simple stock example in the text, price an instrument which pays $1 in state 1 [cf(t,1) = 1] and $-1 in state 2 [cf(t,2) = -1]. What is the expected return to this asset? What is its beta with respect to the stock? How does this relate to the breakdown of Eq. (8.7)?
