Slavery And Information, Giuseppe Dari-Mattiacci

Giuseppe Dari-Mattiacci

This article shows how asymmetric information shaped slavery by determining the likelihood of manumission. A theoretical model explains the need to offer positive incentive to slaves working in occupations characterized by a high degree of asymmetric information. As a result, masters freed (and, more generally, rewarded) slaves who performed well. The model’s implications are then tested against the available evidence: both in Rome and in the Atlantic world, slaves with high-asymmetric-information tasks had greater chances of manumission. The analysis also sheds light on the master’s choices of carrots versus sticks and of labor versus slavery.
