We investigate the extent of variation in output sharing in land rental contracts and alternative hypotheses to explain this variation. Close to half of the rental contracts in our study in northern Ethiopia have output shares that deviate from the dominant 50–50 equal sharing. Variation in land quality, the relative bargaining power of landlords and tenants, production risks and shocks are hypothesised to influence output shares. Matched data of landlords and tenants are used. The importance of endogenous matching of landlords and tenants is investigated by assessing how endogenous tenant characteristics are correlated with landlord characteristics. We find evidence of negative assortative matching for key resource characteristics. A control function approach is used to control for endogenous matching in the output share models. The results reveal that production risks, as well as relative bargaining power, affect output shares in the reverse tenancy setting where tenants are relatively wealthier and more influential than landlords.

土地租赁合同中产出份额的变化和内生匹配：来自埃塞俄比亚的证据

我们调查了土地租赁合同中产出共享的变化程度，并用其他假设来解释这种变化。在我们在埃塞俄比亚北部的研究中，近一半的租赁合同的产出份额偏离了占主导地位的50–50平均分配。假设土地质量的变化，房东和房客的相对议价能力，生产风险和冲击会影响产出份额。使用房东和租户的匹配数据。通过评估内生租户特征与房东特征之间的关系，研究了房东与租户内生匹配的重要性。我们发现关键资源特征的负分类匹配的证据。控制函数方法用于控制输出份额模型中的内生匹配。
