Rulemakers’ Professional Experience and Rulemaking Efficiency in U.S. Federal Agencies

I explore the potential impact of rulemakers’ professional experience on the efficiency of rulemaking by U.S. federal agencies. I highlight two types of professional experience rulemakers may have—inside experience gathered by working in the federal government, if not the same agency, and outside experience gained before entering the civil service or between stints in government. I discuss several plausible mechanisms through which inside and outside experience may affect rulemaking efficiency. Using data combining rulemakers’ career backgrounds with rulemaking life-cycles from 1999 to 2023, I show that outside experience, and not inside experience, is associated with two measures of rulemaking efficiency: a higher likelihood for proposed rules to be promulgated as final and a lower likelihood of unanticipated events—extensions of public comment periods, other delays to the rulemaking timetable, and the withdrawal of rules already issued.
