Reputation, not third-party enforcement, governs diamond market transactions.

Evidence

If dealers really did rely on arbitration to resolve most disputes, one would expect that if it were not available more disputes would go to court. This is not observed; litigation between two nonmembers is also infrequent. Similarly, if reputation bonds were not strong enough to enforce arbitration judgments, one would expect to see frequent recourse to the courts for judicial confirmation of arbitrated judgments. This is also not observed. Thus, it appears that the dispute resolution institutions in the diamond industry can fairly be called extralegal: it is primarily the fear of damage to reputation that maintains discipline in the diamond trade, not the bourse’s board of arbitrators or the procedural right to appeal arbitrated decisions in court. — Lisa Bernestein, Opting out of the Legal System, 252

Diamond dealers consistently maintain that transactions between two club members, between two nonmembers, and between a member and a nonmember are conducted in exactly the same way. If the availability of the DDC’s arbitration system and enforcement mechanisms were central to parties’ ex ante decision making, the terms of the transaction (either substantive or price) should be different when at least one party is a nonmember. For example, a member seller who would sell a stone to another member on thirty-day terms would be expected to charge a nonmember a higher price (or perhaps demand cash on the spot) to compensate for the risk of nonpayment and the unavailability of arbitration. Dealers insist, however, that no such differences exist and that they decide who to deal with purely on the basis of the other party’s reputation. — Lisa Bernestein, Opting out of the Legal System, 250

Categorization

• XREF: Directly supports the reader’s thesis: third-party enforcement is hollowed out because reputation-based social sanctions do the real work — analogous to Coleman’s network closure but here functioning against formal institutions. — connects to: Secrecy and private offices displace open trading for large diamond dealers. — Lisa Bernestein, Opting out of the Legal System, 41; Undetectable diamond treatments shift verification burden onto reputation chains. — Lisa Bernestein, Opting out of the Legal System, 131; Transaction costs alone cannot explain the diamond industry’s rejection of legal contracts — Lisa Bernestein, Opting out of the Legal System, 137 (+9 more)
• DEEPTHINKING: The strong empirical inference from absence of evidence — both counterfactuals (no arbitration available, no enforcement of awards) fail to produce litigation — is a clean quasi-natural experiment establishing the exogeneity of reputation.
• QUESTION: If the arbitration system exists yet isn’t priced into terms, is it essentially vestigial, or does its mere availability change reputation dynamics in ways dealers don’t consciously account for?
• corroborated: 2 independent passages support this claim — Lisa Bernestein, Opting out of the Legal System, 252; Lisa Bernestein, Opting out of the Legal System, 250
