Abstract: A key market institution is the degree of accountability to which the officials involved in regulation are exposed. While elected officials strive for re-election, appointed ones are career-concerned. Provided that the effort exerted to uncover the firm's unknown cost is sufficiently effective in swaying votes, elected officials produce more information than appointed ones do. As a result, when the demand is inelastic, appointment induces wider allocative distortions and higher profits which, in turn, yield stronger incentives to invest. Hence, appointment will prevail on election when investment inducement is sufficiently relevant and shareholders are sufficiently more powerful than consumers. Data on electricity rates and costs, and the methods of selecting regulators and appellate judges for a panel of forty-seven U.S. states confirm these predictions.
