英文文献摘要：
This work has developed a theoretically consistent model of a farm household's choice between working on-farm and working off-farm and the effects of that choice on farm investment choices. The theory demonstrates the potential for wages driven by local economic conditions to be more important to dairy farm investment decisions than characteristics of dairy farms and farmers. The switching regression model developed from the theory is then tested with data from a representative sample of Wisconsin dairy farms. The econometric results demonstrate the importance of wages to farm investment decisions.

这项研究建立了一个理论上一致的模型，描述了农户在从事农场工作和从事非农工作之间的选择，以及这种选择对农业投资选择的影响。该理论表明，由当地经济条件驱动的工资潜力，比奶牛场和奶农的特征对奶牛场投资决策更重要。然后，利用威斯康辛州奶牛场的一个代表性样本的数据，对基于该理论建立的转换回归模型进行了检验。计量经济学结果表明了工资对农业投资决策的重要性。
