What judges maximize:toward an economic psychology of the judicial utility function

Posner proposes that federal appellate judges' income from judicial work and moonlighting is maximized within the constraint of time spent on leisure: he argues that judges' voting behavior be conceptualized as consumption, and that judges avoid the hard work and hassle involved in writing opinions. I propose that the terms entering the judicial utility function be simplified to judicial and non-judicial income, and consumption, some of which is enjoyed during leisure time but a proportion of which is enjoyed in working time (voting, reputation, avoidance of criticism, etc.) Moreover, the extent to which a judge experiences judicial work as laborious and hassling depends upon his cognitive style: adaptors and innovators are expected to conceptualize and experience the detailed work of opinion writing in different ways and thus to have distinct preferences for competing sources of utility.
