These consequences of acceptance of rules should most definitely be part of a cost-benefit analysis of prospective rules. Formulating rule-consequentialism in terms of the consequences of acceptance allows them to be part of this analysis. In fact, consideration of assurance and incentive effects has played a large role in the development of rule-consequentialism (Harsanyi 1977, 1982: 56–61; 1993: 116–18; Brandt 1979: 271–77; 1988: 346ff [1992: 142ff.]; 1996: 126, 144; Johnson 1991, especially chs. 3, 4, 9).
