Family linkages,social interactions,and investment in human capital: A theoretical analysis

This paper introduces parent–child interactions into the Beckerian model of human capital. The acquisition of human capital, jointly determined by parental investment and child effort, is an equilibrium outcome of the intergenerational interactions, which is Pareto efficient within the family. We show that the equilibrium output of human capital is not affected by the parental authority over child behavior, but it is usually lower than the level that maximizes the instantaneous aggregate family welfare. In a family with more than one child, siblings not only compete for parental investments but also directly interact with each other in their effort choices. Exploring intragenerational connections and their interplay with intergenerational forces, we present a more complete theory of family linkages in human development and its implications for the rise and fall of families. Social interactions among children from different families induce intragenerational feedback effects that are further amplified by intrafamily interactions and accelerate regression toward the mean in the economic status of families.     

Parental actions and sibling inequality

This paper presents a simple model of resource allocation within the family. The model is based on two main assumptions: there are nonconvexities in human capital investments and parents cannot borrow to finance their children's education. The model shows that poor and middle-income parents will often find it optimal to channel human capital investments into a few of their children, thus creating sizable inequalities among siblings. The paper shows that the predictions of the model are consistent with the available evidence for three Latin American countries.     

Moving to safety and staying in school: The effects of violence on enrollment decisions in Mexico

There is a vast literature documenting negative impacts of crime on human capital accumulation, which has focused on large‐scale armed conflicts affecting both individuals and infrastructure. However, there is much less evidence in contexts where violence is not accompanied by the destruction of infrastructure. To fill this gap, this paper studies the effects of Mexico's War on Drugs (WoD) on individuals’ schooling decisions. Our results show only small effects of violence on total enrollment of children and young adults, in contrast to recent studies which find significant negative effects for some specific age‐by‐gender groups. Our analysis, which aims to assess the overall impacts of the WoD on enrollment decisions and takes advantage of various rounds of administrative data, the population census, and labor force surveys, shows that many families responded to the increase in violence by migrating to less affected municipalities. However, we find that their education decisions have been quite robust as greater violence did not affect their probability of being enrolled in school. In the long term, however, it is still possible that the increase in violence affects human capital accumulation through indirect effects arising in skill acquisition in early childhood and other stages.     

人口老龄化、公共人力资本投资与 经济增长*

本文利用内生化老龄化的世代交叠模型,探讨了老龄化社会中为了促进经济增长可选择的公共人力资本投资的最优相对规模和结构。本文研究表明,公共人力资本投资相对规模（即占GDP比例）和公共健康支出占比（即占公共人力资本投资比例）均与经济增长呈倒U型关系,且最优值通过老龄化对经济增长的作用表现出来。即当老龄化对经济增长有促进（抑制）作用时,政府促进经济增长的政策是提高（降低）人力资本投资相对规模和公共健康支出占比。基于中国省级面板数据的实证研究发现,老龄化不利于经济增长,公共人力资本投资相对规模及公共健康支出占比偏大,均处在倒U型曲线的下降阶段,分别通过挤出对经济增长更具促进作用的私人投资、公共物质资本投资和公共教育支出而不利于经济增长。本文的政策含义是,政府需提高公共教育支出占比,引导和鼓励更有效率的社会私人资本进行人力资本投资,以逐步降低公共人力资本投资的相对规模。当前公共物质资本投资则需继续加强。     

Ageing,fertility, and growth

This paper analyses the interaction between human capital accumulation, fertility, and labour participation of families in the presence of technology shocks. Altruistic families spend time on the education of their children to increase their level of human capital. Compensating transfers through negative bequests are blocked by an active bequest constraint. Productivity shocks increase the opportunity costs of children and may cause a drop in fertility, which results in population ageing. We investigate the effects of ageing on allocation and welfare in the presence of a Pay-As-You-Go (PAYG) pension system.     

Demographic change and long‐term growth in China: Past developments and the future challenge of aging

This paper explores the influence of demographic changes, particularly the sharp decline in fertility and the evolution of the population age structure, on economic development in China. A general equilibrium overlapping generations model with endogenous decisions on fertility, educational investment, and factor accumulation is employed for our analysis. The family support provided by children to the elderly, which is a component of traditional culture in Chinese society, is also considered. We find that technological changes matter most for growth. Demographic changes, on average, account for approximately 4% of the growth in China, while the effect is negative in the pre‐1980 period. With an extension to include population aging, we find that aging is not necessarily adverse to growth. This finding reflects the fact that a longer life expectancy requires more savings and makes educational investment in children more attractive, which accelerates physical capital and human capital accumulation. However, if the social norm of family support for aging parents is strict, aging will significantly increase the children's burden and crowd out physical and human capital accumulation.     

更多兄弟姐妹是否降低个人教育成就?—来自中国家庭的微观证据

文章利用多个微观数据集,检验我国家庭内同胞数量的增加是否会降低个体教育成就,以及这种影响是否因个体性别而存在差异.实证结果给出了肯定的答案:兄弟姐妹会对个体产生教育挤占效应,并且这种效应存在显著的性别差异.即个体的兄弟姐妹数量增加,将导致个体的受教育年限下降,无论个体是男是女都如此,但对女性来说这种效应会更加严重.上述结论在多个微观数据集和系列检验中均显示稳健.研究还表明,中国家庭偏好男孩的传统观念以及劳动力市场的性别歧视,是导致同胞数量对女性的教育挤占效应更加严重的重要原因.文章的研究结论对改善女性在教育中受到的歧视具有重要的政策含义.     

Why is the rate of single-parenthood lower in Canada than in the U.S.? A dynamic equilibrium analysis of welfare policies

Abstract .  A critical question in the design of welfare policies is whether to target aid according to household composition, as was done in the U.S. under the Aid to Families with Dependent Children (AFDC) program, or to rely exclusively on means-testing, as in Canada. Restricting aid to single mothers, for instance, has the potential to distort behaviour along three demographic margins: marriage, fertility, and divorce. We contrast the Canadian and the U.S. policies within an equilibrium model of household formation and human capital investment on children. Policy differences we consider are eligibility, dependence of transfers on the number of children, and generosity of transfers. Our simulations indicate that the policy differences can account for the higher rate of single-parenthood in the U.S. They also show that Canadian welfare policy is more effective for fostering human capital accumulation among children from poor families. Interestingly, a majority of agents in our benchmark economy prefers a welfare system that targets single mothers (as the U.S. system does), yet (unlike the U.S. system) does not make transfers dependent on the number of children.

The Layoff Rat Race*

We investigate how discretionary investments in general and specific human capital are affected by the possibility of layoffs. After investments are made, firms may have to lay off workers, and will do so in inverse order of the profit that each worker generates. Greater skill investments, especially in specific human capital, contribute more to a firm's bottom line, so that workers who make those investments will be laid off last. We show that as long as workers' bargaining positions are not too weak, workers invest in specific human capital in order to reduce layoff probabilities. Indeed, workers over‐invest in skill acquisition from a social perspective whenever their bargaining power is strong enough, even though they only receive a share of any investment. More generally, we characterize how equilibrium skill investments are affected by the distribution of worker abilities within firms, the probability that a firm will downsize, and the distribution of employment opportunities in the economy.     

Do Population Control Policies Induce More Human Capital Investment? Twins, Birth Weight and China's "One-Child" Policy

In this paper, we address the issues of whether reductions in fertility increase human capital investments per child and whether twinning can identify the quantity–quality (Q–Q) trade-off. We show that estimates of the effects of twinning at higher parities on the outcomes of older children in prior studies do not identify family-size effects but are confounded by inter-child allocation effects because of the endowment deficit and close spacing of twins. However, examining the effects of twinning by birth order, net of the effects stemming from the endowment deficit of twins, can provide upper and lower bounds on the trade-off between the family size and average child quality. Our estimates, based on data from China, indicate that an extra child at parity one or at parity two, net of one component of birth-endowment effects associated with birth weight, significantly decreases the schooling progress, the expected college enrolment, grades in school and the assessed health of all children in the family. Despite the evident significant trade-off between number of children and child quality in China, the findings suggest that the contribution of the one-child policy in China to the development of its human capital was modest.     

教育、闲暇与经济增长--理论模型与实证研究

本文通过把消费者时间分为工作时间、教育时间、闲暇时间,重点扩展了闲暇时间对人力资本积累作用和技术进步的外部性,将闲暇时间和教育时间同时引入经济增长模型中分析了两种时间对经济增长的影响和最优平衡增长路径.随后进行了实证研究,结果表明:我国教育时间(即人力资本投资)对中国经济增长有很大的拉动作用,同时,积极健康的闲暇活动能够促进经济增长,但是由于我国处于工业化阶段,对闲暇的偏好还很低,总体上闲暇时间对我国经济增长有微弱的抑制作用.因此,合理安排闲暇活动和正规教育活动对我国经济增长有重要意义.     

should Transfers To Poor Families Be Conditional On School Attendance? A Household Bargaining Perspective*

This article considers the welfare implications of transfers to poor families that are conditional on school attendance and other forms of investment in children's human capital. Family decisions are assumed to be the result of (generalized) Nash bargaining between the two parents. We show that, as long as bequests are zero, conditional transfers are better for children than unconditional transfers. The mother's welfare may also be improved by conditional transfers. Thus, conditioning transfers to bequest‐constrained families have potentially desirable intergenerational and intragenerational welfare effects. Conditioning transfers to unconstrained families make every family member worse off.     

人力资本投资结构与经济增长——基于包含教育资本、健康资本的内生增长模型理论研究

文章针对已有的关于人力资本投资的理论研究往往只关注于人力资本投资数量而忽视人力资本投资结构的现状,把教育和健康看作两种资本,分析了人力资本投资结构的具体构成形式。假设人力资本由教育资本和健康资本按照Cobb-Douglas生产技术形式组合生成,在扩展MRW模型的基础上,文章构建了一个内生经济增长模型。分析结论表明人力资本投资结构制约着经济增长,人力资本投资结构和数量(存量)都对经济产生重要影响。     

AIDS crisis and growth

We investigate an OLG economy where an AIDS epidemic influences human capital accumulation and growth through the creation of large numbers of orphans. We study how intra-family allocations regarding school and work time of children are adjusted in the face of AIDS within a family, and how, in turn, these adjustments influence accumulation of physical and human capital. We compute the aggregate effects of an AIDS epidemic on human and physical capital accumulation and growth. We find that growth effects of an AIDS epidemic are large. Some policies such as subsidization of AIDS medication have relatively small effects.     

Remittances and the human capital of children: New evidence from Kyrgyzstan during revolution and financial crisis, 2005–2009

We analyze the effect of the receipt of remittances on the education and health of children in Kyrgyzstan during a volatile period of their recent history, 2005–2009. The country experienced revolution in 2005 and the global financial crisis beginning in 2008. Both events impact human capital investment, and the changes vary by region of the country. We use fixed effects estimation and fixed effects, instrumental variables estimation to isolate the effects of remittances and other events on human capital. We find that boys aged 14–18 in remittances’ receiving households are less likely to be enrolled in school than other children. We also find that girls in remittances’ receiving households are more likely to be malnourished (thin). Both effects are relatively small. Remittances do not improve the human capital of children left behind. However, we do find an overall positive improvement in school enrollment among young children between 2005 and 2009 but a negative trend in enrollment among older boys and girls. Nutrition improves over time. Regional differences are apparent in these trends in nutrition and education.     

Should Education be Publicly Provided?

This study suggests that a subsidy in the form of public provision has the potential to be the most efficient educational policy because it stimulates investment in human capital, which would otherwise be inefficiently low because of distortionary income taxation and possible external benefits. Moreover, it can potentially do this without grossly distorting the mix of investments in human capital. Other policies do not have the potential to achieve both these ends without introducing additional, perhaps overwhelming, problems. Thus public provision of education appears to provide incentives for human capital accumulation which are more efficient than any other feasible policy.     

Financial crises,debt overhang,and firm growth in transition economies

ABSTRACT

We examine the effects of the global financial crisis of 2008 and the European debt crisis of 2011 on the relationship between capital structure, investments, and performance for Eastern European companies. While the existing literature documents how firms’ investments are sensitive to the availability of internal funds and to debt holdings, we further investigate whether this investment sensitivity also translates in different levels of performance, and document that capital structure indeed has both a direct and an indirect effect, mediated by the capital expenditure channel. We show that firms with higher financial flexibility experience higher investments and returns on capital. Over-levered firms instead suffer from a debt overhang condition, forcing them to curb investments, and consequently experiencing lower performance. Overall, we provide evidence on the importance of capital structure and financial flexibility on investments and performance, showing the real consequences of the debt overhang condition on firm value creation. Firms should therefore aim at maintaining adequate financial flexibility in order to be able to pursue future profitable investment opportunities, and avoid the under-investment problem arising from a debt overhang situation.     

Replacing Corporate Income Tax with a Cash Flow Tax

We design a parsimonious cash flow tax for Australia and estimate revenue effects. It allows immediate deduction of all capital expenditures, denies deductions of interest payments, and compensates negative cash flows at the same rate and time as it taxes positive cash flows. It allows taxpayer timing choice on implementation over 10 years. It has incentive effects comparable to lowering the corporate income tax rate to zero. It removes distortions that artificially favour debt over equity, short- over long-term investments, rents over competitive returns, large, established over small and new businesses, and conventional over innovative investments. It closes international tax evasion loopholes. Its spur to investment and timing of revenue impacts favours implementation in recession.
