The Law Merchant and related legal codes evolved considerably over time. In addition to providing a court of law especially suited for merchants, it fostered significant legal developments that reduced the transaction costs of exchange (North, 1989, ch. 13).

The same also held for the new practices of credit agreements and insurance. — PAUL R. MILGRO, PAUL R. MILGRO - THE ROLE OF…, 33
