M. Alexander Pearl has posted “Of ‘Texans’ and ‘Custers’: Maximizing Welfare and Efficiency Through Informal Norms,” forthcoming in the Roger Williams University Law Review, on SSRN.
Here is the abstract:
Professor Robert Ellickson (Yale) theorized that the informal norms of a close-knit community maximize aggregate welfare and Professor Barak Richman (Duke) identified two distinct types of private ordering systems: “shadow of law” and “order without law.” Under the Ellickson-Richman structure, many Indian tribes qualify as close-knit groups where informal norms effectively operate. The additional trait of isolation — both geographic and cultural — makes them ideal communities for the prioritization of informal norms. The imposition of external law, such as state law, is harmful and unnecessary to the maintenance of order in these communities. Recent legislative efforts to ameliorate criminal problems in Indian Country miss the mark and an alternative solution prioritizing the operation of informal norms and private ordering should prevail over application of external law and structures.
This article expands upon Ellickson’s assessment of how social behavior is affected by law and other forces, such as the informal norms in a given social group. Part I explains Ellickson’s theory and analyzes other important contributions made by other scholars. Part II discusses the taxonomy of historical and current examples of communities utilizing informal norms, or private law based mechanisms, to resolve disputes and how efficient results that maximize welfare (as defined by the community) are achieved. Part III, addresses the question of whether government law enforcement interferes with the close-knit community to an extent great enough to diminish the efficacy, or existence, of operative informal norms. Part IV examines anthropological sources to argue that the unique attributes of various Indian tribes and tribal communities warrant definition as the type of close-knit communities contemplated under Ellickson’s theory. Part V explains why the informal norms of certain tribal communities should be allowed to operate without interference from outside legal forces (Custers). Finally, Part VI looks at the relevant provisions in the recently passed Tribal Law and Order Act of 2010 and asks whether they effectively address the criminal justice issues facing Indian tribes subject to State criminal jurisdiction.
