Contracts are examined when outcomes depend on managers' choices as we
ll as efforts. As the cost of effort shrinks relative to payoffs, the
optimal contract converges to a linear payoff if the control space of
the agent has full dimensionality, but not otherwise. Thus, when the a
gent can trade expected return for greater correlation with other retu
rns, it is better to ignore relative performance when the cost of effo
rt is small. When the choices include all fair gambles and hedges, the
linear schedule is no more expensive than any other schedule that ind
uces effort. Unfair gambles are examined as well.
