PAUL R. MILGRO — PAUL R. MILGRO - THE ROLE OF INSTITUTIONS IN THE REVIVAL OF TRADE - THE LAW MERCHANT, PRIVATE JUDGES, AND THE CHAMPAGNE FAIRS

73 published claims from this book.

• A continuing relationship functions as a forfeitable bond against cheating.
• A judgment-holder gains nothing by querying the information agency, only costs.
• A Law Merchant institution can sustain honest trade as an equilibrium
• A private forum can incentivize information-gathering by tying appeals to prior queries.
• A private judge can solve collective punishment problems by centralizing information and adjudication.
• A stylized model can capture universal incentive problems across varying historical instances.
• A trader pays a judgment only when expected future trade gains exceed the cost.
• Bilateral reputation systems fail because information and sanctioning are costly public goods
• Centralized adjudicators solve trade by combining information storage with dispute resolution
• Centralizing reputation records cuts the cost of checking any trading partner.
• Cheating tempts traders while cooperation yields shared gains.
• Checking single-step deviations suffices to verify a sequential equilibrium
• Commercial law developed before states enforced contracts at scale.
• Community boycotts can sustain cooperative trade as equilibrium without fixed trading partners.
• Community ostracism alone may be insufficient to enforce trade judgments
• Community reputational enforcement works even without repeated bilateral interaction between traders.
• Controlled entry to the Champagne Fairs substituted for direct credit checks and enforced reputation.
• Cooperation can survive even when cheating pays seven times more per round.
• Cooperation survives even when cheating pays hugely and system costs are steep.
• Costly information is what breaks informal trade enforcement.
• Costly information, not infrequent trade, is the core obstacle to honest exchange.
• Enforcement of legal judgments depends on the technology and liquidity of wealth transfer.
• Entrenched reputation mechanisms give dominant fairs a durable competitive moat.
• Entry control at fairs substituted for reputational screening of trade partners
• Extortion fails when victims expect repeated bribes and refuse the first.
• Extralegal contracting needs reputational information plus cheap formalities to signal formation.
• Formal judges strengthen reputation systems rather than replace them.
• Full-history information institutions are too costly for efficient trade
• Group reputation for fair dealing drives a trading bourse’s economic viability.
• Group-wide reputation can bond honest behavior even between strangers who rarely meet.
• Growing trade communities face monitoring and one-shot-cheating problems that demand new institutions.
• In anonymous random matching, no trader’s behavior ever affects future partners.
• Informal punishment fails because traders won’t boycott lucrative partners
• Information about partners’ past behavior is essential for punishing cheaters.
• Institutions across cultures evolved mainly to publicize who violated communal norms.
• Institutions emerge where information is costly, not where enforcement is absent.
• Legal innovations follow new commercial practices as they arise.
• Litigation costs only matter as deterrents and are never paid at equilibrium.
• Long-distance trade needs institutions to fill knowledge gaps about others’ honesty
• Long-distance trade undermines honest behavior among strangers without institutions.
• Medieval European commerce was governed by private merchant law, not state law
• Medieval merchant institutions existed to overcome the spatial limits of reputation mechanisms.
• Medieval merchants developed private commercial law without state enforcement
• Merchants developed private legal codes governing long-distance trade before any nation-state existed.
• Observable disputes in trade cannot be resolved without verification of the underlying claims
• One-shot strategic games can lock rational players into collectively worse outcomes.
• One-shot trade games yield cheating as the unique equilibrium.
• Ostracism, not state force, enforced medieval merchant law
• Pre-state commercial law judges made reputation systems work where direct knowledge failed
• Pre-state trading communities sustained honesty through reputation systems backed by private judges.
• Private adjudication could function without state enforcement powers.
• Private bourse dispute-resolution and secrecy keep the diamond trade extralegal and low-breach.
• Private enforcement institutions restore cooperation but impose priced transaction costs.
• Private judges bundle self-interested services with community-benefiting enforcement
• Private trade-enforcement systems fail when wealth transfer is costly
• Private-judge trading systems succeed only when enforcement costs stay low
• Punishing cheaters by withdrawing cooperation acts as third-party enforcement within the trading community.
• Repeated trade with a high discount factor enables cooperative equilibria.
• Reputation alone cannot sustain honest trading without third-party registration.
• Reputation and institutions are complementary, not substitute, enforcement mechanisms.
• Reputation systems fail because monitoring and sanctioning are costly public goods.
• Reputation systems need cheap information flow, not frequent repeated trade, to enforce honesty.
• Some enforcement costs are unavoidable for sustaining honest exchange.
• State contract enforcement mattered mainly by lowering policing costs, not by filling a void.
• State enforcement supplanted communal reputation as the guarantor of commercial judgments.
• Strong incentives make the legal-merchant strategy robust to any history
• Sustained long-distance trade requires that reneging on agreements be unprofitable.
• The hardest enforcement problem is deterring judge bribery.
• The judge’s reputation value is itself a check against bribery and extortion.
• The mere threat of dispute costs can deter cheating without real costs being paid.
• Trade institutions must solve both an information and a punishment-motivation problem
• Trustworthy behavior requires some information cost, but imperfect information can suffice.
• Word-of-mouth reputation alone cannot sustain honest trade.
