We consider the principal shareholders agent manager problem in connection with investment and CEO compensation under two types of limited commitment where the principal worries about model uncertainty and exhibits ambiguity averse with respect to the true probability Consistent with maxmin criterion a robust principal makes decisions under some endogenous worst case In the case of limited commitment on the manager side the firm invests less and average q and marginal q are always lowered in the presence of ambiguity However in the case of limited commitment on the shareholder side ambiguity induces under investment and over investment simultaneously and has different implications for average q and marginal q Moreover the robust compensation contract features time varying compensation no matter whether the limited commitment constraints bind or not which is contrary to the conventional wisdom Finally the optimal sensitivity of continuation utility increases with ambiguity aversion 2022
