英文文献摘要：
This paper test farm households' joint decisions to work off-farm, and their investments in farm capital respectively, using a farm level data set involving 252 sole proprietorships in Southwestern Minnesota. Time series are collected from the period 1993 through 2002 and estimation is done using a recursive two-step simultaneous censored equations model. Strong support is found for endogeneity of farm capital in an off-farm reliance model as well as for of off-farm income reliance in a farm capital model. In addition, evidence of true state dependence in off-farm income reliance is supported by the data.

摘要本文利用一个涉及明尼苏达州西南部252家独资企业的农场水平数据集，分别测试了农户从事非农工作的共同决策及其对农场资本的投资。时间序列是从1993年到2002年期间收集的，并使用递推的两步同时截尾方程模型进行估计。我们发现，非农依赖模型中农业资本的内生性得到了有力支持，而农业资本模型中非农收入的内生性也得到了有力支持。此外，这些数据支持了非农收入依赖中真正的国家依赖的证据。
