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.  相似文献

African agricultural production is modeled as a sequential decision process, with men's labor first allotted to clearing, then women's labor allotted to harvesting. A switching regression is then used to measure the constraints due to clearing labor capacity and harvesting labor capacity. The import of men's clearing labor depends on the valuation of shadow wages. Output appears to be more frequently constrained by husband's clearing labor, and in this situation male labor appears under‐utilized. However, output is also significantly constrained by female harvest labor, although the findings imply that female labor is over‐utilized at this stage.  相似文献

This article introduces a method for estimating structural labor supply models in the presence of unobservable wages and deviations of households' marginal revenue product of self‐employed labor from their shadow wage. This method is therefore robust to a wide range of assumptions about labor allocation decisions in the presence of uncertainty, market frictions, locational preferences, etc. We illustrate the method using data from rice producers in Côte d'Ivoire. These data, like previous studies, reveal significant systematic differences between shadow wages and the marginal revenue product of family farm labor. We demonstrate how one can exploit systematic deviations, in the present case related to household characteristics such as the land/labor endowment ratio, to control for both unobservable wages and prospective allocative inefficiency in labor allocation in structural household labor supply estimation.  相似文献

[目的]农地退耕是土地利用变化的重要组成部分,明晰农地退耕的影响因素可以为山区生态恢复提供新的路径。[方法]文章基于武陵山区180份农户调查数据,采用多元线性回归模型分析影响山区农地退耕的因素,重点分析山区农村劳动力转移对农地退耕的影响。[结果](1)研究区劳动力转移现象明显,85%的农户家庭存在不同程度的劳动力转移,劳动力转移比例达到51.61%,户均转移劳动力数量占家庭总人口的29.90%;(2)研究区农户退耕较为普遍,退耕农户占样本农户的55%,户均退耕面积0.31hm2;(3)非农收入和农业劳动力比例对农户的退耕面积产生了显著的正向影响,同时家庭女性劳动力数量、家庭总人数、承包地面积、种植耕地的总块数、两个地区哑变量——万木乡和丁市镇也显著影响了农户的退耕地面积。[结论]山区农村劳动力转移带来的非农收入增加促进了农户的农地退耕,但是劳动力转移带来的农业劳动力供给减少又降低了农户的退耕地面积,最终两者的作用相互抵消,使得农村劳动力转移对农户的退耕地面积产生了不可确定的影响。  相似文献

A theoretical model is presented which integrates the consumption and production components of the rural household. A theoretically determined system of expenditure equations, derived factor demand equations and an off-farm labor supply equation are estimated using primary data for Saskatchewan farm households. From the empirical results we conclude that if the wage rate can be observed or estimated, the farm household's behavior can be explained empirically in a manner consistent with received theory. Summary and Conclusions A theoretical model integrating the consumption and production sides of the farm household or enterprise is estimated empirically using primary data for Saskatchewan farm households. The farm household was assumed to maximize its utility function subject to farm production and cash flow constraints. The empirical results indicate that the theoretical model can be estimated successfully even when data are sparse. While the coefficients for the expenditure, derived demand, and off-farm labor supply equations are consistent with coefficients from similar equations estimated separately by others, the theoretically more precise integrated approach specifies the simultaneous effect of the variables across equations. From the empirical results and the theoretical considerations it is obvious that the wage rate is a key explanatory variable in the model. The wage rate links the three components of the model–final expenditures, the derived input demands and off-farm labor hours. The wage rate is one determinant of the allocation of the operator's time (although other factors such as the nature of the operation and opportunities to work off-farm dominated in this study), and both the wage rate and the allocation of the time determine the eventual income available to the rural household. In essence, then, the problem of explaining farm household behavior when the household's business enterprise function cannot be separated from its consumption activity is similar to that of traditional models based on the theory of the firm and models of consumer behavior. The only difference is that the wage rate is observable in the traditional models but needs to be estimated as a shadow price in models which seek to explain rural household behavior. As a result, research in this area must start with an explanation of the allocation of (at least) the operator's labor and a measure of the shadow wage rate. If the entire household's allocation of time between on-farm and off-farm labor and leisure is determined, it is possible to treat its consumption and production activities separately. Further research is required to extend the model to explain household labor supply to both the farm and off-farm labor markets.  相似文献

根据劳动力转移新经济学理论和家庭内部劳动力分工理论,基于2018年浙江省14个县(市)681户营林调查户样本数据,运用Tobit模型分析了非农就业对营林劳动力女性化的影响。结果表明:非农就业对女性劳动力单位面积营林投工量和女性营林投工比例具有显著正向影响;非农就业对不同林种营林投入女性化有明显差异,对经济林农户家庭营林投工女性化有显著正向影响,而对用材林农户家庭营林投工女性化作用不明显。提出完善农村劳动力社会保障制度;加强农村女性劳动力营林生产技能培训;发挥女性劳动力的营林生产优势等建议。  相似文献

基于浙江省龙游县5个行政村115户农户268块竹林地投入产出数据,采用DEA模型对竹林生产效率进行测度,运用Tobit模型进行计量分析,从空间和时间角度分析劳动力转移对竹林生产效率的影响。结果表明:竹林地的综合效率、纯技术效率及规模效率的均值分别为0.470、0.560及0.842,竹林地的生产效率相对较低;劳均非农就业时间、劳动力转移类型的复合性、竹林收入占家庭收入比例及户主年龄对竹林地生产效率有显著正向影响,家庭竹林地总块数对竹林地生产效率有显著的负向影响。因此,提出改善竹林投入、提高生产效率的相关对策建议。  相似文献

农民收入的困境与“三农”问题的逻辑——江苏视角   总被引:1,自引:0,他引:1  
江苏省农村居民家庭收入具有区域差异性、农业贡献递减性和工资性来源主导性等基本特征。就业选择对农民纯收入影响的分析表明,劳动力产业转移的收入效应单调递增,不同劳动力转移模式的收入效应各异,行业技术密集度的收入效应为正。研究认为,农民收入问题的解决必须放在宏观经济发展的框架下考虑,不能与"农业问题"混为一谈;解决"农民问题"和"农村问题"的关键在于努力增加人力资本,拓展就业空间,提升就业稳定性;解决"三农"问题的关键在于加大体制、机制改革的力度,建立向"三农"倾斜的外部环境。  相似文献

The reaction of labor markets to economic reforms is an important indicator of the progress of transition. Because of diminished government support and the breakup of state and collective enterprises, labor market adjustments in the transition economies have been particularly severe in the agricultural sector. This article evaluates the off-farm labor market for a sample of agrarian households in transition Bulgaria. We give particular attention to the distributional assumptions that underlie standard approaches to the evaluation of labor supply. A variety of specification tests are considered and support for standard maximum likelihood estimates which rely on normality as a maintained hypothesis is mixed. Alternative semiparametric (distribution-free) estimators are also considered. The empirical results indicate that, five years after the initiation of the transition, off-farm labor supply patterns for Bulgarian agricultural households are similar to what is commonly observed in developed market economies. Labor supply is positively affected by factors such as education and work experience which are hypothesized to increase off-farm wages. Social benefit programs providing monetary or in-kind support payments are shown to significantly decrease off-farm work.  相似文献

Since high-yielding modern rice varieties (MVs) are adopted only in favorable production environments, significant regional productivity differentials have emerged in Nepal. This study explores the distributional consequences of such differential MV adoption based on an intensive survey of favorable and unfavorable villages. We found that MV adoption increased returns to land but decreased family labor earnings from rice production, as it facilitated the substitution of hired for family labor. As a result, the differential MV adoption did not significantly worsen the household income distribution according to the results of the counterfactual Gini decomposition analysis.  相似文献
