When the probability of apprehension is the same for all individuals, optimal sanctions will be maximal: as Gary Becker (1968) suggested, raising sanctions and reducing the probability of apprehension saves enforcement resources. This argument necessarily holds only when the enforcement authority knows how difficult an individual will be to apprehend before expending any investigative resources. When differences among individuals exist and can be observed only after apprehension, or not at all, optimal enforcement may involve less than maximal sanctions. ER -
