ABSTRACT: This paper revisits the principal-agent model with moral hazard when its solution is obtained invoking the first-order-approach. We show that the solution can be economically inconsistent even when “sufficient conditions” ensuring its validity ([1,2]) hold. To be more precise, we provide examples where is impossible to find Lagrange multipliers validating the approach. The correct solution to the problem provides a rationale for option-like contracts and minimum payments.
