Regulation of a Risk Averse Firm

We extend the Laffont–Tirole regulation model to the case of risk-averse firms. Our main results are:

• The impact of risk aversion is to shift the optimal contract toward a cost-plus contract.

• As compared with the risk-neutral case, distortions are greater and informational rents are smaller.

• For high levels of risk aversion, the optimal contract involves cost ceilings and the less efficient firms are bunched together.
