“…Self-policing based on residual claimancy appears to be effective in the regulation of common pool resources such as fisheries, irrigation, and grazing lands (Ostrom, 1990), in the regulation of work effort in producer cooperatives (Greenberg, 1986;Craig and Pencavel, 1995), and in the enforcement of non-collateralized credit contracts (Banerjee et al, 1994). Experimental studies (Frohlich et al, 1998) provide additional support for the effects of residual claimancy in inducing lower supervision costs and higher productivity in (small) work teams. Further, the fact that residual claimancy may provide incentives for self-policing even in quite complex settings and large groups is suggested by evidence that in the United States home ownership is a significant predictor of participation in community organizations (Glaeser and DiPasquale, 1999) and local politics but, significantly, not national politics (Verba et al, 1995), as well as a willingness to sanction coresidents who transgress social norms (Sampson et al, 1997).…”
