Transactional framework of sharecropping: empirical evidence
收集近期证据验证Chew提出的分成制佃农交换框架假说，即马歇尔均衡是常态而张五常均衡罕见，结果支持马歇尔均衡，间接支持该框架。
Chew [Chew, Tek-Ann, 1991. Share contracts in Malaysian rubber smallholdings. Land Econ., 67: 85–98; Chew, Tek-Ann, 1993. The Transactional framework of sharecropping: further implications. Can. J. Agric. Econ., 41: 209–221.] proposed a transactional framework of sharecropping that accommodates both the Marshallian and the Cheungian equilibria. An important conclusion arising thereof is the hypothesis that Cheung's sharecropping equilibrium is the rarity while the Marshallian equilibrium is the norm. In this paper, we collated some recent evidences to verify this hypothesis. The evidences support the Marshallian equilibrium, thereby providing indirect support for the transactional framework of sharecropping.
