Non-global social contracts: A note on inefficient social institutions

This paper explores some perverse features that can emerge when social contracts are moved from a social vacuum to a setting of social interdependence. In particular we note incentives that might exist in conjunction with externality problems that yield situations in which: (1) social contracts reduce social wealth; (2) sub-global social contracts are Pareto inferior to the absence of social contracts; (3) there are no incentives for global social contracts. While previous works emphasized the benefits of contracts, this paper focuses on their costs. A conclusion reached is that perhaps justice and efficiency demand not a single global social contract but rather a rich melange of sub-global contracts with appropriate interstices of anarchy.
