英文文献作者：Bettis, Lee W.,Meyer, RIchard L.,Walker, Francis E.
英文文献摘要：
Incentives exist for landowners to employ sharecroppers in Northeast Brazil. Four components of a typical sharecropping contract were parameterized. The sensitivity of landowner income, number of sharecroppers employed and enterprise mixes revealed unexpected relationships. These results are important to policymakers interested in regulating sharecropper contracts.
