摘要

本研究有助于确定影响参与非洲粮食市场决策的因素。与以往的研究不同,我们将劳动力市场参与引入农户模型,以突出决策中的异质性。在经验上,我们依赖于Heckman方法的扩展,并引入控制函数来缓解与农业技术采用相关的内生性问题。我们发现,交通基础设施的限制,通过抑制粮食供应,限制了家庭经历劳动力过剩;价格激励可能对市场制度的选择产生相反的影响,尽管对生产的影响可能对已经参与其中的家庭是积极的。我们还表明,农民对粮食价格的反应对他们的劳动力市场地位并不敏感。农业技术的使用促进了谷物生产和外部农业劳动力的就业。因此,本研究为制定促进市场营销和农村就业的政策提供了更好的目标。

A Crossed Analysis of Participations in Labor and Grain Markets: Evidence from Malawi
This study contributes to the literature on the identification of factors shaping the decision to participate in the grain market in Africa. Unlike previous studies, we introduce labor market participation into the farm household model to highlight heterogeneities in decision making. Empirically, we rely on an extension of Heckman's approach and introduce control functions to mitigate endogeneity issues related to the adoption of agricultural technologies. We find that limited access to transportation infrastructure, by discouraging the supply of grain, constrains households to experience an excess of labor; price incentives may have a reverse effect on the choice of market regimes, even though the effect on production may be positive for households that are already participants. We also show that farmers' responses to grain prices are not sensitive to their labor market position. The use of agricultural technologies encourages cereal production and employment of external agricultural labor. This study thus provides a better targeting when designing policies promoting marketing and rural employment.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
