Shadow Wages and Shadow Income in Farmers’ Labor Supply Functions
提出一种新方法，在不估计生产函数的情况下推导影子工资和影子收入，并用越南农民数据验证了该方法与理论一致。
Abstract This article extends the current literature on estimating the labor supply function in agriculture by providing a different method to derive the shadow wage and shadow income. The method is based on the observation that the shadow wage is the marginal product of labor at the optimal point of both farm and household production functions. Thus, under certain assumptions on the functional form of the production functions, both the shadow wage and shadow income can be derived without estimating the production function. Using a sample of Vietnamese farmers, the results from the new method are shown to be consistent with the theory.
