Faynzilberg and Kumar (Rev Econ Design 5(1):23-58, 2000) show that the usual Mirrlees Rogerson conditions to validate the first-order approach in moral hazard agency models are no longer valid in the generalized agency case. They consider the risk-averse agent case and identify one set of technological conditions, where the production technology satisfies the linear distribution function condition in actions and types, that validates ex-ante the first-order approach. With the usefulness of their decomposition approach, we show that the first-order approach in the generalized agency case can be checked ex-ante under the MirrleesRogerson conditions when the agent is risk-neutral but there is a binding limited liability constraint on the agent’s wage.
