Rural Population Growth, 1950–1990: The Roles of Human Capital, Industry Structure, and Government Policy

Human capital raises rural incomes, but this effect is swamped by higher returns to human capital in urban markets. This leads to "brain drain" from rural areas. Populations grow more rapidly in rural counties that have a diversified employment base. Farm population grows faster (or declines more slowly) in counties with relatively high farm income, and nonfarm populations grow faster in counties with relatively high nonfarm income. However, higher farm incomes lead to slower nonfarm population growth and vice versa. Rural county government services financed by local taxes or debt have neutral or negative effects on population growth.     

Employment Dynamics and Linkages in the Rural Economy: Insights from Senegal

Evidence on rural wage employment is thin and lacks nuance for different employment sources, insights on dynamic effects, and an understanding of the channels of effects. We assess conceptually and empirically the direct and indirect welfare effects of entry and continuation in different types of wage employment in rural Senegal. Using panel data, fixed effects and first-difference estimation, we show substantial positive welfare and linkage effects. We find that participation in wage employment increases per capita income by 143%, and reduces poverty, poverty gap and food insecurity by, respectively, 63%, 89% and 48%. While the direct effect on income is larger for non-agricultural and contractual wage employment, the indirect income effects through self-employment are more pronounced for agricultural and casual wage employment. Our results imply that job creation is important for rural development, that wage employment in agriculture can lead to considerable growth multiplier effects, and that synergies exist between large-scale and small-scale agriculture.     

集体林权改革制度下农户劳动力分配情况分析——基于辽宁省农户调查数据

利用辽宁省5个县农户2000、2006、2010年的面板数据,进行林改前后农户劳动力分配变化、产权安全对农户就业影响的回归分析,结果表明:林改后随着户均林地面积的增加,农户增加了对林业的投工,林业生产与非农就业存在一定程度的替代性,但随着农户年龄、教育水平的增长,非农就业,特别是工资性劳动的投工呈增长趋势;产权安全的增长对农户加强林业生产有正相关关系。     

Market and Cost Structure in the U.S. Beef Packing Industry: A Plant-Level Analysis

A resurgence of consolidation in the U.S. meat packing industry in the past few decades has stimulated academic and policy debate. Issues raised include the role of cost economies in driving these patterns, and the effects on the agricultural sector (cattle producers) from market power. Here, plant level cost and revenue data for U.S. beef packing plants are used to estimate a cost-based model incorporating cattle- and output-market pricing behavior. The robust results indicate little market power exploitation in either the cattle input or beef output markets, and that any apparent evidence is counteracted by cost efficiencies such as utilization and scope economies.     

新冠肺炎疫情对2020年农业农村发展的影响评估与应对建议

由于种养业季节性强、农民工流动性大、农村防护条件差,疫情对农业农村发展的影响具有全面性和持久性。研究显示,疫情防控导致的物流中断,家禽养殖企业遭遇生存危机,导致短期肉价下跌和2020年肉类供需紧张局面加剧;果蔬滞销、粮食销售延迟以及部分农产品消费抑制,将使相当部分种植户2020年收益面临下滑;疫情期间的延期复工和疫情后的长期停工会导致农民工就业人数下降205万人至351.1万人,2020年农民工人均工资收入名义增长速度可能将下降1.45至2.46个百分点。综合考虑疫情对各项收入来源的影响,2020年农村居民人均可支配收入名义增长速度可能将下降2.59至3.59个百分点。因此,应加紧建立应急储备和加大供需调节力度,以补贴和政策性信贷支持引导龙头企业帮助小农户度过难关,加大对农民工再就业培训和返乡创业的支持,多渠道稳定农民收入。     

Employment Growth, Worker Mobility, and Rural Economic Development

A county-level labor market model is estimated for North Carolina. The model accounts for inter-county commuting, migration, and within-county adjustments to labor demand shocks. Econometric results indicate that most employment growth (70–80%) during the 1980s was accommodated by changes in commuting flows. Evidence is also presented indicating that labor force growth—and, by extension, population growth and associated fiscal impacts—in rural counties is sensitive to employment growth in nearby urban counties. These results highlight two opposing forces related to spatial spillovers that are usually neglected in analyses of the economic and fiscal impacts of employment growth.

Labour Demand in the Post‐apartheid South African Wine Industry

In 2013 the minimum agricultural wage in South Africa was increased by an unprecedented 51%. We use data on 77 Western Cape Province wine grape farms from 2005–2015 to estimate the impacts on employment. Previous post‐apartheid labour market reforms increased minimum wages substantially, but re‐entry to global markets after sanctions were lifted increased demand and this preserved jobs in the wine sector. However, by 2005 this demand growth had largely ceased. The long‐run wage elasticity for permanent employees was found to be ?0.4, but for casual workers the figure was ?4.7, so the 51% wage increase is likely to decimate casual employment in the future. Thus, the poorest and most vulnerable casual workers lose most in terms of jobs, incomes and secure livelihoods, whereas 80% of full‐time staff benefit from the higher minimum wages. Thus, the minimum wage change is likely to increase the gap between privileged permanent staff and casual workers. This result is not surprising in view of the long‐standing interdependence between farmers and their permanent workers in wine grape production.

Demand for Seasonal Wage Labour in Agriculture: What Does Family Farming Hide?

This article draws on the agricultural household literature to understand the dynamics of wage labour on farms in a context of family farming. The recent evolution towards an increased use of seasonal wage labour motivates the original distinction of three types of labour: family labour, permanent‐wage labour and seasonal‐wage labour. Considering the two wage labour types and hiring cost for seasonal workers, our empirical results based on 2000 French data on fruit and vegetable farms suggest that the choice between hiring permanent or seasonal wage labour is not only determined by the seasonality of the activity. Indeed, the characteristics of the local labour market also affect the trade‐off between permanent and seasonal wage labour. This result provides insights on the substitutability of the two labour types, especially when the local labour market is tight. Moreover, the substitution of seasonal‐wage labour for permanent‐wage labour can occur in the agricultural sector as a mean of increasing flexibility as well as reducing costs and commitments. Finally, family labour is found to substitute for wage labour and more specifically for seasonal‐wage labour.     

贫困地区农业结构调整对农民收入的影响——重庆五区县实证分析

本文利用重庆贫困地区5个区县619户农户实地调查资料,着重从农产品商品率和现金收入的变化,分析了农业结构调整对贫困地区农户人均纯收入的影响。同时探讨了农业结构调整对农户增收的影响因素。经过计算和分析认为:农民人均纯收入的变化中,贡献率最大的是外出打工等工资性收入,农业纯收入增量的贡献率不到1/3。且农业纯收入增量中,由于商品率提高带来的现金收入增量也不到一半。因此可以说,农业结构调整对农户收入的提高产生了一定影响,但作用有限。另外,农村基础设施建设,如道路、电力通讯等设施建设是影响农业结构调整对农民增收作用的重要因素。     

A Regional Analysis Of The Supply And Demand Of Farm Labor In Canada

This is an aggregative study covering the years 1946 to 1962, with the primary objective of examining the most significant factors which affect a market structure for farm labor. A recursive system is used to derive an equilibrium level of both hired and family farm labor during the period studied as well as an equilibrium level of future farm labor requirement by 1970 .
The findings show that the demand for farm labor was apparently not, or weakly, responsive to the farm wage rate in all regions and it was weakly responsive to the parity ratio, farm machinery and productivity. On the supply side, farm labor also was not, or weakly, responsive to the variables included in all regions with the exception of the farm wage rate or parity ratio in B.C. and the adjusted non-farm wage rate and farm machinery in the Atlantic region. The results also show that, in Canada as a whole, the projected family labor employment will be 294,000 manequivalents by 1910 or 42 percent decline as compared to the 1962 level, while the projected hired labor employment will be 114,000 manequivalents in 1970 or 14 percent increase in the eight years after 1962. This would likely be the tendency because of the continuous economic development on the one hand and the consolidation of farms on the other .     

贵州省百香果种植适宜性评价

目的 百香果近几年在贵州域内推广种植,因当地整体气候环境条件与其最优生境条件存在较大差异,导致部分地区百香果无法越冬、成熟果实产量和质量较低等问题,因此分析贵州省百香果种植适宜性对其产业化发展具有指导意义。方法 文章将百香果种植适宜性评价体系分为两层：生长适宜层与现状限制层,生长适宜层除了5项常规生长指标（常年均温、最冷月均温等）外,考虑贵州百香果种植低产、质低的问题,引入百香果关键生长期（5—11月、7—8月）的温度作为生长指标之一;现状限制层包括5种不宜种植的土地利用类型和重度石漠化、极度石漠化以及坡度大于25°地区。运用空间叠加、栅格计算以及空间统计等GIS方法得出百香果种植适宜评价结果。结果 （1）评价等级面积：不适宜>次适宜>适宜,面积分别为1 456.096 457万hm²、274.224 849万hm²、31.348 694万hm²,全省无最适宜区分布。（2）次适宜区面积较广,但在黔西和黔中地区分布面积较少;适宜区涉及到25区县,81.71%适宜区集中在南北盘江流域低热河谷区域。（3）以适宜性评价结果为基础,区县为基本单元,根据适宜性程度进行百香果产业发展区划,其中重点5个、一般区11个、分散选育区27个、非推荐种植区45个。（4）可种植百香果贫困区县有22个,占贫困县总数的66.67%。结论 贵州省不适宜大面积种植百香果,33个贫困县中10个贫困县区县可作为百香果产业发展区。

农地规模化流转背景下的农业雇佣生产合约:理论模型及实证分析

在中国农地规模化流转的背景下,农业雇佣生产成为客观事实。本文基于多任务委托—代理思想,通过建立农业雇佣生产合约模型,从合约激励角度推演出三种典型的合约形式,即固定工资+过程监督、计件工资+事后客观评估、固定工资+收益分成+事后主(客)观评估。进一步地,本文借助经验素材证实了上述合约形式的存在及其合理性。研究结果表明:在雇佣采茶情景下,采用固定工资+过程监督合约会导致采茶工、茶农和社会三方出现效率损失和福利损失,计件工资+事后客观评估合约优于固定工资+过程监督合约。     

The impact of the 2008 financial crisis on dynamic productivity growth of the Spanish food manufacturing industry. An impulse response analysis

The emergence of a financial crisis is an event that can impact the fortunes of nearly all economic agents. The focus here is on the 2008 financial crisis and how firms’ productivity growth was impacted by this crisis in the years that followed. This article focuses on dynamic productivity growth and its components using a firm‐level data set of Spanish meat processing, dairy processing, and oils and fats firms. The impulse response analysis shows that the impact of the crisis on dynamic productivity growth is negative and persistent in the oils and fats industry, initially positive but then negative in the meat processing industry, and positive in the dairy processing industry. The observed magnitudes of change in indicator are between 2% and 5% for oils and fats industries, and of 1% in both dairy and meat industries. Our analysis further confirms that firms’ size is an important factor in explaining how crisis impacts dynamic productivity growth and its components, while we find only slight evidence regarding the firms’ experience in the market.     

How Labourers Fare in Fresh Fruit Export Industries: Lemon Production in Northern Argentina

Horticultural export industries have been acclaimed as promoting employment and growth. Critics, however, contend that most of the jobs created are low wage jobs. This article examines whether field labourers fared better than previously in a well positioned, producer-driven, innovative horticultural export industry. Our findings indicate that workers initially fared badly and we identify the strategies used to cap wages. Real wages and seasonal incomes increased significantly from 2002, but only after producers were pressured by government and the union regained political power. Contrary to expectation, escalating consumer demands for high-quality healthy fruit and responsible agronomic practices contributed to producers' response to the union's demands. We argue that the monitoring technologies and practices required by buyers allowed large producers to gain greater information about the role of field labourers in the production process and the transaction costs associated with unreliable, poorly trained occasional harvesters. Nevertheless, even after real wages rose, only few harvesting families managed to escape poverty at the height of the season.

Developing Economic Indexes for the Quebec Hog/Pork Industry

The Quebec hog/pork industry has grown significantly over the last 25 years. Explanations of this growth in the literature have centered on government policies, expansion of profitable market opportunities, and reforms in marketing institutions. A coincident index model that trends with total hog slaughters in Quebec is estimated using a dynamic factor model. It implicitly defines a variable that measures the overall state of economic activity in the Quebec hog/pork industry. The results show that reforms in hog marketing institutions are strongly correlated with the economic expansion of the industry. A leading economic index also forecasts the growth of the coincident index using leading variables. The overall statistical performance of the leading coincident index is disappointing, but the growth in American inventories of frozen pork meat is shown to have useful predictive value.
