Convertible Husbandry vs. Regular Common Fields: A Model on the Relative Efficiency of Medieval Field Systems
通过测算中世纪英格兰可转换农业与常规公地的生产率，发现两者大致相当，并解释可转换农业在中世纪表现不佳的原因在于土壤条件和不当管理，而近代早期其生产率提升则归功于饲料豆科植物的引入。
The existing literature on the economy of medieval England views the practice of convertible husbandry as a more efficient alternative to regular common fields. The article challenges this view by measuring the productivities of the systems, which are found to be approximately equivalent. In interpreting this finding, it is suggested that edaphic conditions and wrongful managerial practices account for the poor performance of convertible husbandry during the Middle Ages, whereas the greater productivity achieved by the system in the early modern period is attributed to the introduction of fodder legumes, such as clover, which were absent in previous centuries.
