Estimating a labour supply function of farm households
利用包含收入和休闲的效用函数以及非线性预算约束，估计了奶牛场家庭劳动供给弹性，发现内生工资弹性较小。
The supply elasticity of family labour on dairy farms is estimated using a utility function with income and leisure as variables, and a non-linear budget constraint linking income through a quadratic production function to labour supply. Using a local linear approximation to this constraint and distinguishing one other variable input, the endogenous wage elasticity of labour supply is derived. It turns out to be small.
