The Jurisprudence of American Slave Sales
分析了所有涉及奴隶买卖的上诉案件，发现南方法院帮助降低了奴隶交易成本，且奴隶买卖法在成熟度上超越了同时期的其他商法，原因在于买卖双方信息差距大、奴隶财产价值高以及法律规则替代了自由劳动市场的雇佣法。
An analysis of all appellate cases involving slave-sales reveals that southern courts helped minimize the costs of trading in slaves. Slave-sales law also surpassed other contemporaneous commercial law in sophistication. Why? Greater information gaps between slave buyers and sellers called for more complex institutional support. The enormous property value embodied by slaves also led to more litigation, greater need for settled law, and a more even match of power between plaintiff and defendant. Additionally, legal rules surrounding slave sales substituted for the employment law governing free-labor markets.
