Farm Poverty and Safety Nets

Farm families with incomes below the poverty line are far less likely than wealthier farmers to receive farm support payments. Using data from the 1989–2004 Current Population Survey, we find that poor farm families are also not participating in other assistance programs. Controlling for other factors, eligible farm families have substantially lower participation rates in the Food Stamp Program and in Medicaid than eligible nonfarm families. Removing farm safety net program payments would increase the number of farmers eligible for these programs but, in the absence of behavioral changes, would only lead to small increases in the number of recipients.     

农户科学储粮技术认知与采用意愿研究——基于山东省的实证分析

山东是经济发达的产粮大省,农户科学储粮技术在山东的试点对全国其它地区具有示范作用与借鉴意义。文章基于山东361户农户调查数据资料,首先考察"农户科学储粮专项"试点背景下农户2010~2012连续3年的小麦与玉米年末存量、储存方式、储藏损失、储粮目的及储存效果,然后对农户科学储粮技术的认知、采用及其效果进行描述性统计分析,并运用Logistic模型深入探究影响农户科学储粮技术采用意愿的个人及家庭特征因素。结果表明:农户近3年来粮食储量稳定,主要储粮方式是袋装与缸装,损耗来源于鼠害、虫害及霉菌;科学储粮技术效果明显,但普及率低;大多数农户具有技术采用意愿;家庭人口学特征与粮食生产、消费和储备情况及农户对技术的了解情况在不同程度上影响其技术采用意愿。主要政策建议与启示为:扩大试点范围,开发不同技术满足各类农户需求,并探索适当的补贴机制、构建技术服务体系,融"科学储粮工程"于新农村建设及农业服务体系之中。

Off‐farm labor market decisions and agricultural shocks among rural households in Kenya

Using household level data from rural Kenya, this article explores whether and how farm households respond to unfavorable agricultural production environments, including any ex post adjustments in off‐farm labor supply in response to unexpected weather shocks. While controlling for a wide range of educational, demographic, and other locational factors, we examine how long‐term weather conditions and specific rainfall shocks influence a household's decision to engage in, and their earnings from, the off‐farm labor market. We find that rural households engage in off‐farm work as a long‐term strategy to deal with the effects of anticipated weather conditions on their farming operations. The analysis does not reveal major short‐term adjustments in off‐farm engagement as a result of specific, unexpected rainfall shocks; these households do however rely on remittance income and petty agricultural wage labor under these circumstances. Holding other factors constant, and conditional on participation, households in areas with a more productive local agriculture tend to earn more from off‐farm work especially in the informal/business sector than their counterparts in regions with a less productive agriculture. As expected, a vibrant local economy in the form of public investment increases the probability of off‐farm participation.     

农村劳动力市场发育对农村土地流转的影响分析——基于农户调查的实证研究

利用农户调查数据,运用多元回归模型实证分析了农村劳动力市场发育对农地流转的影响。模型估算结果表明：在表征农村劳动力市场发育程度的四个变量中,工资自主决定程度对农地转出率影响最大,回归系数达到了0.528,即该变量每增加一个单位将会使农地转出率增长52.8%。就业流动自由度对农地转出率的影响也比较大,回归系数为0.423。就业市场服务体系完善程度对农地转出率的影响相对较小,回归系数为0.126。在此基础上,得出相应的政策启示。
