A method has been proposed to form the optimal structure of regional state investments, which contributes to the strategic goals and objectives of the socio-economic development of a region through the advanced development of human capital. The dynamic model has been considered representing a mathematical programming problem, which describes in the form of recurrent dependences the chain of channels of influence: "the structure and volume of investments→the indicators of the regional human capital→the indicators for the socio-economic development of a region". The weighted average of degrees in achieving the target values of resulting indicators of socio-economic development of a region on the considered horizon of planning has been used as the objective function. Recurrent dependences are the lag econometric models of panel data involving the main components. To construct three types of models (the through models, those with the deterministic and random spatial effects) using the Best Subset method, the open-source software R was employed. The best models were chosen with the help of tests by Wald, Hausman, and Breusch–Pagan. The limitations within the model are a series of assumptions about the processes of the development of human capital and the socio-economic development considering the uncertainties. The optimization variables are shares of the distribution of investment resources based on the investment directions and years. Based on the results of modeling and numerical calculations on the example of several regions of Russia in dynamics over the years, the optimal investment structure has been proposed. A given structure enables making the maximum progress towards achieving the target values of strategic indicators of the development of a region through the development of human capital
提出了一种形成区域国家投资最优结构的方法,通过人力资本的先进发展,为区域社会经济发展的战略目标和目标做出贡献。人们认为,动态模型代表了一个数学规划问题,它以循环依赖关系的形式描述了影响渠道链:"投资结构和数量→区域人力资本指标→区域社会经济发展指标"。在考虑的规划范围内,一个区域的社会经济发展指标达到目标值的程度的加权平均值被用作目标函数。循环依赖是涉及主要成分的面板数据的滞后计量模型。采用最优子集方法构建三种模型(through模型、确定性模型和随机空间效应模型),采用开源软件R。最好的模型是在Wald、Hausman和Breusch-Pagan的测试帮助下选出的。该模型的局限性在于考虑到不确定性,对人力资本发展过程和社会经济发展过程进行了一系列假设。优化变量是基于投资方向和年份的投资资源分配份额。基于多年来俄罗斯多个地区动态的建模和数值计算结果,提出了最优投资结构。一个特定的结构能够通过人力资本的发展在实现一个区域发展战略指标的目标值方面取得最大的进展

Teacher Labor Markets in Developing Countries 发展中国家的教师劳动力市场
Pub Date : 2020-02-24 DOI: 10.2139/ssrn.3542654
Lee Crawfurd, Todd Pugatch
The types of workers recruited into teaching and their allocation across classrooms can greatly influence a country's stock of human capital. This paper considers how markets and non-market institutions determine the quantity, wages, skills, and spatial distribution of teachers in developing countries. Schools are a major source of employment in developing countries, particularly for women and professionals. Teacher compensation is also a large share of public budgets. Teacher labor markets in developing countries are likely to grow further as teacher quality becomes a greater focus of education policy, including under the United Nations Sustainable Development Goals. Theoretical approaches to teacher labor markets have emphasized the role of non-market institutions, such as government and unions, and other frictions in teacher employment and wages. The evidence supports the existence and importance of such frictions in how teacher labor markets function. In many countries, large gaps in pay and quality exist between teachers and other professionals; teachers in public and private schools; teachers on permanent and temporary contracts; and teachers in urban and rural areas. Teacher supply increases with wages, though teacher quality does not necessarily increase. However, most evidence comes from studies of short-term effects among existing teachers. Evidence on effects in the long-term, on the supply of new teachers, or on changes in non-pecuniary compensation is scarcer.
招聘到教学部门的工人类型及其在各个教室的分配可以极大地影响一个国家的人力资本存量。本文考虑了市场和非市场机构如何决定发展中国家教师的数量、工资、技能和空间分布。学校是发展中国家就业的主要来源,特别是对妇女和专业人员而言。教师薪酬也占公共预算的很大一部分。随着教师质量成为包括联合国可持续发展目标在内的教育政策的更大重点,发展中国家的教师劳动力市场可能会进一步增长。教师劳动力市场的理论方法强调了非市场机构的作用,如政府和工会,以及教师就业和工资中的其他摩擦。证据支持这种摩擦在教师劳动力市场如何运作中的存在和重要性。在许多国家,教师和其他专业人员之间在薪酬和质量方面存在巨大差距;公立和私立学校的教师;签订长期和临时合同的教师;以及城市和农村的教师。教师供给随着工资的增加而增加,尽管教师质量不一定会提高。然而,大多数证据来自对现有教师的短期影响的研究。关于长期影响、新教师供应或非金钱补偿变化的证据较少。

The object of research is the human capital of the agricultural sector of the national economy. The study of scientific works has revealed that in defining the essence of human capital as an economic category, scientists have not reached a common opinion. With all the variety of theoretical approaches, the problem of the peculiarities of human capital formation in the agricultural sector remains insufficiently studied. There are significant differences in methodological approaches to the interpretation of its essence at different levels of manifestation and certainty. The methods of systematic approach and structural-functional analysis, abstract-logical, monographic and graphical methods were used in the research. The study identifies the nature and peculiarities of human capital formation in the agrarian sector of the economy and clarifies the human capital functions of the agrarian sector and the factors that contribute to its development. In the work on the basis of generalization of theoretical researches on the role of human capital in the economy, its state and prospects of development in the agrarian sector of economy are analyzed. The factors that influence the level of formation and development of human capital are analyzed. The functions of human capital are described and ways to improve the available human capital in rural areas are proposed. The peculiarities of the human capital of the agrarian sector of the economy are revealed, the main of which are: – close connection of the human capital of the agrarian sector with the rural way of life, agrarian work and life; – significant social and professional homogeneity; – great dependence of its use on natural rhythms and cycles; – significant territorial dispersion of the human capital of the agricultural sector, its relatively low mobility compared to human capital in other sectors of the national economy; – need for development and development under conditions of disability due to the lower standard and quality of life in rural areas, etc.
本文的研究对象是国民经济中农业部门的人力资本。对科学著作的研究表明,在将人力资本的本质定义为一个经济范畴的问题上,科学家们并没有达成共识。尽管有各种各样的理论方法,但对农业部门人力资本形成的特殊性问题的研究仍然不足。在不同的表现和确定性层面上,对其本质的解释在方法论上存在显著差异。研究方法采用系统方法和结构-功能分析法、抽象-逻辑法、专著法和图解法。该研究确定了农业经济部门人力资本形成的性质和特点,并阐明了农业部门的人力资本职能及其发展的因素。在对人力资本在经济中的作用的理论研究进行概括的基础上,分析了人力资本在农业经济中的现状和发展前景。分析了影响人力资本形成和发展水平的因素。阐述了人力资本的功能,提出了提高农村可利用人力资本的途径。揭示了农业经济部门人力资本的特殊性,主要表现在:农业经济部门人力资本与农村生活方式、农业生产和生活密切相关;-显著的社会和职业同质性;-很大程度上依赖于自然节奏和周期;-农业部门人力资本在地域上明显分散,与国民经济其他部门的人力资本相比,其流动性相对较低;-由于乡郊地区的生活水平和质素较低,发展需要和残疾情况下的发展等。

Effects of Globalisation on Human Resources Practice in Nigeria Oil & Gas Industry 全球化对尼日利亚油气行业人力资源实践的影响
Pub Date : 2020-02-05 DOI: 10.2139/ssrn.3532759
Samuel Ajayi
The roles and responsibilities of Human Resources departments are transforming as the modern business faces pressures of globalization. The local supply of talent is short of its long-term demand in Nigeria oil and gas industry, and the gap is a challenge for operators in the Hydrocarbon industry in Nigeria and other areas. The shortage between the demand and supply of talent is likely to continue to increase, notably for high skilled workers and for the next generation of business executives. Now organizations in this sector are required to place greater emphasis on attracting, developing and retaining human capital for their short and long term business needs. To remain in profitable and sustainable operation global staffing and management of a workforce diverse in culture and language skills, and dispersed in different nations are the key goals of global human resources. Only those organizations with systems and processes in place that support quick and easy adaptation to their human resource practices in line with the changing global labor market conditions will be able to attract and retain high performing and motivated employees. Companies with the ability to foresee their business needs and their workforce needs – especially for high skills – will gain the decisive competitive advantage.
随着现代企业面临全球化的压力,人力资源部门的角色和职责正在发生转变。尼日利亚油气行业的人才供不应求,这对尼日利亚油气行业和其他地区的运营商来说是一个挑战。人才供需之间的短缺可能会继续加剧,尤其是对高技能工人和下一代企业高管而言。现在,该部门的组织需要更加重视吸引、发展和保留人力资本,以满足其短期和长期的业务需求。全球人力资源的关键目标是保持盈利和可持续的运作,对文化和语言技能不同、分散在不同国家的劳动力进行全球人员配置和管理。只有那些拥有系统和流程的组织,能够根据不断变化的全球劳动力市场条件,快速、轻松地适应其人力资源实践,才能吸引并留住高绩效和积极进取的员工。有能力预见其业务需求和劳动力需求(特别是高技能人才)的公司将获得决定性的竞争优势。

Issues and Challenges in Agripreneurship 农业创业中的问题与挑战
Pub Date : 2020-02-04 DOI: 10.2139/ssrn.3531626
Pradeep Kumar
India's Economy is principally dominated by Agriculture with more than 70% population dependent onagriculture. It accounts for about 14% of Gross Domestic Products of the country. India being predominantly agricultural, agripreneurs play very vital and important role in the agricultural value chain. They contribute significantly to increase the agricultural GDP by the process of their value addition. In order to tap the untapped potential rich and unexplored rural resources, agripreneurship has a huge scope. Significant growth in manufacturing and service sectors is contributing for the better living conditions and lifestyle of urban population whereas agriculture and allied sectors are still in back foot in providing the better living conditions in rural India. This paper highlights the issues and challenges in agripreneurship.
印度经济主要以农业为主,超过70%的人口依赖农业。它约占该国国内生产总值的14%。印度以农业为主,农业企业家在农业价值链中发挥着非常重要的作用。它们通过自身的增值过程,对提高农业GDP做出了重要贡献。为了挖掘尚未开发的潜在丰富和未开发的农村资源,农业创业有着巨大的空间。制造业和服务业的显著增长为城市人口提供了更好的生活条件和生活方式,而农业和相关部门在为印度农村提供更好的生活条件方面仍然处于落后地位。本文重点介绍了农业创业中存在的问题和面临的挑战。

Early Childhood Care and Cognitive Development 幼儿保育与认知发展
Pub Date : 2020-02-01 DOI: 10.3386/w26813
J. Chaparro, Aaron J. Sojourner, Matthew Wiswall
This paper combines multiple sources of information on early childhood development in a unified model for analysis of a wide range of early childhood policy interventions. We develop a model of child care in which households decide both the quantities and qualities of maternal and non-maternal care along with maternal labor supply. The model introduces a novel parenting-effort channel, whereby child care subsidies that permit less parenting may enable better parenting. To estimate the model, we combine observational data with experimental data from the Infant Health and Development Program (IHDP) which randomly assigned free child care when the child was 1 and 2 years old. We estimate a cognitive skill production function and household preferences, giving insight into mechanisms driving the ex post heterogeneous effects of the IHDP intervention, accounting for alternative care substitutes available to the control group and spillovers of the child care offer across the household's decisions. We also estimate ex ante effects of counterfactual policies such as an offer of lower-quality care, requiring a co-pay for subsidized care, raising the maternal wage offer, or a cash transfer. Finally, we use the model to rationalize existing evidence from outside the US on the effects of universal child care programs.
本文将儿童早期发展的多种信息来源结合在一个统一的模型中,用于分析广泛的儿童早期政策干预措施。我们开发了一种儿童保育模式,其中家庭决定了母亲和非母亲照顾的数量和质量以及母亲的劳动力供应。该模型引入了一种新的养育努力渠道,即允许较少养育的儿童保育补贴可能使更好的养育成为可能。为了评估该模型,我们将观察数据与婴儿健康与发展计划(IHDP)的实验数据结合起来,该计划在儿童1岁和2岁时随机分配免费儿童保育。我们估计了认知技能生产函数和家庭偏好,深入了解了驱动IHDP干预的事后异质性效应的机制,考虑了对照组可用的替代护理替代品以及整个家庭决策中儿童保育服务的溢出效应。我们还估计了反事实政策的事前影响,如提供较低质量的护理,要求共同支付补贴护理,提高产妇工资,或现金转移。最后,我们使用该模型来合理化来自美国以外的关于普遍儿童保育计划影响的现有证据。

Vertical Specialization in North–South Trade: Industrial Relocation, Wage and Welfare 南北贸易纵向专业化:产业转移、工资与福利
Pub Date : 2020-02-01 DOI: 10.1111/roie.12444
H. Kurata, Ryoichi Nomura, Nobuhito Suga
This paper presents a North–South trade model with vertically linked industries and examines how declining costs of trade across stages of production encourage vertical specialization and affect wages and welfare. As trade costs fall below a threshold, the production of all final goods relocates to the South and vertical specialization emerges. In some industries, production of intermediate goods also relocates against comparative costs because of benefits of co‐location, and further declines in trade costs lead to reshoring. A country may temporarily lose from falling trade costs, but both countries can be better off after trade costs fall sufficiently.
本文提出了一个具有垂直联系产业的南北贸易模型,并研究了跨生产阶段的贸易成本下降如何鼓励垂直专业化并影响工资和福利。当贸易成本低于某一阈值时,所有最终产品的生产都将转移到南方,垂直专业化就出现了。在一些行业中,由于同地的好处,中间产品的生产也会相对于比较成本进行转移,而贸易成本的进一步下降会导致回流。一个国家可能会暂时因贸易成本下降而遭受损失,但在贸易成本充分下降后,两国都可能变得更好。

Substitution or Complementation: The Relationship between School Education and Shadow Education 替代还是互补:学校教育与影子教育的关系
Pub Date : 2020-01-31 DOI: 10.2139/ssrn.3534829
Jiali Li
In order to explore the relationship between school education and shadow education, this study applied two-level Bernoulli Model to estimate the school-level determinants of private tutoring by analyzing the data of PISA 2015 of four regions of China (Beijing, Shanghai, Jiangsu, and Guangdong). The results indicated that: (1) the four regions have large scale of private tutoring ranging from 58.7% to 74.0% for science, mathematics, and reading; (2) the participation rate of private tutoring in villages is much higher than that in cities; (3) the quality of school teachers significantly negatively affects the likelihood for receiving tutoring. Shadow education plays both substitutional and complementary roles for school education, and the growth of shadow education is in accompany with the low quality of school education in rural areas but with high quality of school education in urban areas. Instead of increasing Education resources and improving infrastructure, increasing teacher quality will reduce the participation probability of private tutoring.
为了探讨学校教育与影子教育之间的关系,本研究通过分析中国四个地区(北京、上海、江苏和广东)的PISA 2015数据,应用两层伯努利模型来估计学校层面的私人辅导决定因素。结果表明:(1)4个地区科学、数学、阅读的课外辅导比例在58.7% ~ 74.0%之间;(2)农村私教参与率远高于城市;(3)学校教师素质显著负向影响接受辅导的可能性。影子教育对学校教育既有替代作用,又有补充作用,影子教育的发展伴随着农村学校教育质量低、城市学校教育质量高的趋势。提高教师素质会降低私教参与的概率,而不是增加教育资源和改善基础设施。

Shadow education plays both substitutional and complementary roles for school education, and the growth of shadow education is in accompany with the low quality of school education in rural areas but with high quality of school education in urban areas. Instead of increasing Education resources and improving infrastructure, increasing teacher quality will reduce the participation probability of private tutoring.","PeriodicalId":210669,"journal":{"name":"Labor: Human Capital eJournal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132684980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conduct an empirical simulation exercise that gauges the plausible impact of increased rates of college attainment on a variety of measures of income inequality and economic insecurity. Using two different methodological approaches--a distributional approach and a causal parameter approach--we find that increased rates of BA and AA attainment would meaningfully increase economic security for lower income individuals and shrink gaps between the 90th percentile and lower percentiles. Increases in college attainment would not significantly reduce inequality at the very top of the distribution, as measured by the 99/90 earnings ratio.
我们进行了一项实证模拟练习,以衡量大学入学率提高对各种收入不平等和经济不安全感指标的可能影响。使用两种不同的方法方法——分配方法和因果参数方法——我们发现,BA和AA获得率的提高将显著提高低收入个体的经济安全,并缩小第90百分位数与更低百分位数之间的差距。以99/90的收入比率衡量,大学学历的提高不会显著减少收入分配最顶层的不平等。

Teachers’ Monitoring and Schools’ Performance: Evidence from Public Schools in Pakistan 教师监督与学校绩效:来自巴基斯坦公立学校的证据
Pub Date : 2020-01-30 DOI: 10.2139/ssrn.3527951

This paper evaluates the impact of an innovative monitoring system on teacher attendance and school performance in Pakistan. In 2014, the government in Khyber Pakhtunkhwa province introduced the Independent Monitoring Project aiming at increasing teacher attendance in primary and secondary public schools by distributing to the government-hired monitors smart phones with a special data collection software installed. Our analysis is based on a difference-in-differences approach using the country wide Annual Status of Education Report from 2012 to 2016. Our findings suggest that monitoring of government schools has increased teacher attendance by 7.5 percentage points in the first year of intervention. But the positive effect wears off to 2.7 percentage points in the second year. Child attendance and test scores also increased in the first year, but in the second year they disappeared. Especially, in the first year, the monitoring system improved students’ math, reading, and English test scores by 0.13, 0.14, and 0.15 standard deviation, respectively, if they are grades 1-5. This result suggests that teacher attendance has an important role in delivering better student outcomes, but that monitoring should be coupled with appropriate incentive mechanism in order to have a lasting impact.
本文评估了巴基斯坦创新监测系统对教师出勤和学校表现的影响。2014年,开伯尔-普赫图赫瓦省政府推出了独立监测项目,旨在通过向政府雇用的监测员分发安装了特殊数据收集软件的智能手机,提高公立中小学教师的出勤率。我们的分析基于一种差异中的差异方法,使用了2012年至2016年全国年度教育状况报告。我们的研究结果表明,在干预的第一年,对公立学校的监督使教师出勤率提高了7.5个百分点。但这种积极影响在第二年逐渐减弱,降至2.7个百分点。儿童出勤率和考试成绩在第一年也有所提高,但在第二年就消失了。特别是,在第一年,监测系统使1-5年级学生的数学、阅读和英语考试成绩分别提高了0.13、0.14和0.15个标准差。这一结果表明,教师出勤在提供更好的学生成绩方面发挥着重要作用,但为了产生持久的影响,监控应与适当的激励机制相结合。
