In this paper we offer new measures of agricultural productivity advance in the Lower South between 1720 and 1800. Past efforts and quantification have focused exclusively on the region's export performance. In addition to extending and refining measures of regional exports, we develop two new series based on the value of slave labor and on measurements of total agricultural production in the region. Despite differences in their short-term behavior, all of the indices show that long-run productivity improvements were modest at best, and may have been negative. Surprisingly, taking account of production for domestic consumption yields the most favorable long-term performance. ER -
