When Does Member Governance Substitute for Regulation in Consumer-Owned Utilities?

Abstract

Abstract This paper asks when member governance can substitute for external regulation in consumer-owned natural monopolies. Holding quantities fixed, usage-proportional patronage refunds neutralize the transfer motive for monopoly over-pricing, shifting the welfare margin toward operating efficiency. In a principal-agent model, a cooperative board supports and monitors a risk-averse manager under a linear cost-based incentive contract. Regulation reduces the variance of realized operating costs and supports stronger incentives, but it also imposes a compliance burden and displaces the board’s own support and monitoring. Exemption therefore raises effort only when burden relief and stronger internal governance outweigh the loss of external information. Welfare dominance further requires the operating-cost gain to cover changes in effort disutility, governance costs, risk-bearing, and the social value of discretion rents. The case for exemption is therefore conditional rather than categorical and supports hybrid oversight that retains regulatory reporting, auditing, and benchmarking while relaxing behavioral constraints.
