Slavery and Supervision in Comparative Perspective: A Model
扩展了交易成本模型，分析监督与痛苦激励相对于普通奖励在不同活动中的成本收益，解释古代和新世界奴隶制、中世纪英格兰及现代意大利的雇佣劳动、工业合同中的奖惩选择以及当代家长制现象。
The familiar transaction-costs model is extended to allow for the varying costs and benefits of supervision and pain incentives on the one hand, and ordinary rewards on the other, in differentially effort- and care-intensive activities. Applied to unfree labor, this model accounts for the observed patterns of slave governance and manumission in extractive, industrial, agricultural, and service activities in antiquity and in the New World. Applied to free labor, it accounts for wage work on large estates in labor-surplus medieval England or modern Italy, the choice between bonuses and penalties in industrial contracts, and the growing paternalism of our own time.
