Inferring Yields from Probate Inventories

Abstract

An improvement on Mark Overton's method of computing crop yields from probate inventories is proposed. Harvesting costs are explicitly allowed for and a new procedure for eliminating cost-of-production valuations is offered. Applying these methods to a sample of Oxfordshire probate inventories generates higher yields than Overton's investigation of East Anglian inventories. The finding lends support to the view that most of the yield increase in early modern England occurred in the seventeenth century rather than the eighteenth.
