Nutritional efficiency wages and child labor

This paper formally analyzes the incidence of child labor by employing an overlapping-generations general-equilibrium model of a small open economy. An individual's ability determines whether or not he/she becomes a skilled worker. The supply side of the economy is composed of two sectors: a modern sector that produces a homogeneous good using skilled labor and physical capital; and an agrarian sector that produces a traditional good using unskilled adult labor, child labor, and land. An increase in foreign direct investment and improvements in education reduce the incidence of child labor. Emigration of skilled (unskilled) workers reduces (raises) the supply of child labor, while trade sanctions reduce the demand for child labor. Child wage subsidies have an ambiguous effect on the incidence of child labor while education subsidies are effective in reducing the incidence of child labor. Simulation analysis is used to investigate the welfare effects of the aforementioned policies.     

Impact of remittances on male and female labor force participation patterns in Africa: Quasi‐experimental evidence from Ghana

In this paper, we examine how remittances, an outcome of labor mobility, affect labor market activities in Ghana using detailed household and individual‐level data. This is important, considering the extensive literature that has documented the remittance–poverty reduction nexus. First, we find a strong negative association between household remittance‐receiving status and individual labor supply decisions using instrumental variable estimation techniques. Second, we find the depressing effect of remittances on labor supply decisions to be much stronger in rural areas. Rural women who reside in remittance‐receiving households are less likely to be in the labor force compared with those who do not reside in such households. Remittances have very little impact on labor supply decisions in urban areas. Our findings support that remittances can exacerbate long‐term poverty reduction in rural areas through lower labor force participation, and as such rural‐based and gender‐based interventions may be needed to help redirect remittance income.     

人口老龄化对中国劳动力供给的影响

本文描述了我国劳动力供给的总体数量以及变化趋势,并从劳动参与率、城乡结构、人力资本三方面进行考察,探讨人口老龄化对于劳动力供给的影响。我国劳动参与率还存在较大增长空间,将会是未来劳动力供给的重要增长点;农村剩余劳动力存量仍看似充足,但其老龄化情况较严重,难以维持当前农民工向城市转移的速度;另外我国年轻劳动力的教育程度和人力资本已有显著提升。因此虽然人口老龄化已经对我国劳动力供给产生了一定负面影响,但由于人口和劳动力的变化是一个长期过程,并不会给经济发展带来突发的、灾难性的冲击。     

WHOSE LOSSES COUNT? EXAMINING SOME CLAIMS ABOUT AGGREGATION RULES FOR NATURAL RESOURCES DAMAGES

Compensation for natural resources damage may be provided, in principle, by a payment equal to the value of damage, a compensating restoration project, or partial restoration plus a compensating payment. Applicable laws have a pronounced tilt toward restoration. When determining the value of damage, no welfare-economic reason exists to count as an offsetting benefit any utility enjoyed by rubberneckers; nor should damages be excluded when incurred by those unaware of the injury, those whose motivations are thought "non-economic," those who are resource-loving passive users, or those who are parentalistic altruists. Money compensation required on behalf of nonparentalistic altruists drops to zero as active users are fully compensated. However, if (for whatever reason) active users cannot sustain a claim for full compensation, nonparentalistic altruists will suffer compensable losses.     

The British labor market in disequilibrium: Did the dole reduce employment in interwar Britain?

In this paper we estimate an econometric model of the labor market in interwar Britain. We reject the hypothesis that wages adjust sufficiently speedily to clear the labor market in each year in favor of a disequilibrium model in which the level of employment is determined by the lesser of labor demand or supply. We find that the level of unemployment benefits is a key determinant of labor supply. We estimate that a reduction in benefits to approximately half the 1925-38 average would have resulted in an increase in employment of between eight and twelve percent.     

Married women's labor supply and economic development: Evidence from Sri Lankan household data

Women's labor supply in Sri Lanka has increased steadily since the early 1990s following economic reforms, but remains well below the level predicted by national income, a feature shared by a number of Asian and Latin American countries that have undergone similar reforms and economic growth. To understand the microeconomic determinants of women's work in Sri Lanka's growing economy, this paper estimates a binary‐choice model of married women's labor supply using household survey data spanning a 23‐year period. Decomposition and cohort analysis reveal that women have been drawn into the workforce through falling fertility rates, rising tertiary education, and declining income effects among younger generations, but other factors have undermined this positive trend. Educational attainment reduces married women's labor supply except at the tertiary level, consistent with social stigmas associated with married women in non‐white‐collar employment. The strict sectoral segregation of married women by education level supports this hypothesis. In addition, growth has been concentrated in low‐skilled sectors with self‐employment more prevalent, reducing employment prospects of educated women and prompting their labor force withdrawal. This suggests it is the structure of economic development, rather than speed, that matters for women's labor force activity.     

社会保障税与社会保障制度优化

社会保障税是指定用于社会保障的工薪税。本文分析了工薪税的税收归宿和劳动供给弹性的影响。当劳动供给弹性较小时 ,税收主要由劳动力负担 ,而且可能会增加就业压力 ;工薪税在劳动同质程度较高时可以取得较好的再分配效应。本文还描述了社会保障制度优化的理论过程。社会保障制度优化是指现收现付计划和强制储蓄计划的最优搭配 ,它以“黄金律”条件下的隔代帕累托改进为标准。就同代收入再分配而言 ,将收入再分配计划的目标定为提高受益人的受教育水平 ,而不是直接为其提供免费的社会福利 ,将有助于缓解收入再分配的代价。     

Relative Affluence and Child Labor—Explaining a Paradox

Some micro level empirical studies found child labor incidence increasing even with improvement in the economic conditions of the poor. This paper provides a possible explanation as to why increase in absolute income may not be sufficient to solve the problem of child labor. We argue that people in general are not just concerned about their own consumption; they are very much affected by the consumption of their peers. While taking decisions regarding the time allocation of their children between work and leisure, parents do keep an eye on their relative position in the society. We develop a theoretical model of household decision making to show that child labor supply from a poor family can increase even with improvements in its economic conditions, if the family's relative position in the society deteriorates and if the relative status effect is sufficiently strong.     

Foreign Direct Investment and Domestic Child Labor

Empirical evidence suggests that use of child labor as domestic help has increased significantly in recent years although the overall incidence of child labor across the globe has declined satisfactorily. This should draw the attention of economists and policymakers because domestic child labor is considered as exploitative and in many cases hazardous. This paper purports to explain this apparently perplexing finding theoretically in terms of a three‐sector general equilibrium model with a nontraded sector where only child labor is used to render services to the richer section of the society. The analysis shows how FDI‐led economic growth increases the size of the services sector although it lowers the overall incidence of child labor in the economy and improves the welfare of the poor families that supply child labor. Finally, a composite policy has been recommended that can deal with all three aspects favorably.

由于全球劳工形势和企业所有制结构的不利变化以及我国劳动力市场供过于求和供需结构性矛盾等因素的影响,目前我国企业职工享有的权益处于较低水平,企业职工权益保护状况呈现出层次性、差异性和复杂性.强化企业职工权益保护,应构建适应社会主义市场经济本质要求的新型劳动关系,明确劳动者权益保护的基本原则,进一步完善我国的劳动法律体系,健全劳动者权益保护的有效机制,充分发挥政府主导作用和工会、雇主组织的积极作用,平衡劳资双方的力量与权益.     

Asymmetric labor supply

The estimation of labor supply elasticities has been an important issue in the economic literature. Yet all works have estimated conditional mean labor supply functions only. The objective of this paper is to obtain more information on labor supply, estimating a conditional quantile labor supply function. We use a sample of prime age urban males employees in Brazil. Two stage estimators are used as the net wage and nonlabor income are found to be endogenous to the model. Contrary to previous works using conditional mean estimators, it is found that labor supply elasticities vary significantly and asymmetrically across hours of work. While the income and wage elasticities at the standard work week are zero, for those working longer hours the elasticities are negative.     

不能离开生产关系探讨分配问题--关于分配问题的一些看法

分配是人与人之间的经济关系。在社会主义初级阶段,总起来看,按劳分配为主、按劳分配与按要素分配相结合的分配方式是惟一公平的。我们应该正确认识和处理分配过程中出现的剥削和两极分化现象并最终要以消灭它为目标,当然这要随着条件的成熟逐步实现,而且还是一个十分漫长的历史过程。但是,这不等于理论教育中可以回避剥削和两极分化问题。     

Socially responsible products: what motivates consumers to pay a premium?

The motivation to pay a premium for socially responsible products is partly an expression of consumer concern for the well-being of those involved in the production process. Buying a product with a socially responsible label, and donating to a charity are similarly motivated actions. While there is an extensive literature on the economics of charitable giving that examines motivations to donate as well as on the impacts of labelling on consumer demand, there is little overlap between the two literatures. We bridge these two literatures by investigating whether consumers have heterogeneous motivations for paying a premium. Through a laboratory experiment that auctions coffee with hypothetical socially responsible labels that put different weights on in-kind versus cash transfers, we find that those consumers who prefer an in-kind transfer (paternalistic altruists) are willing to pay a 52.5% price premium over standard coffee. Those who prefer that most of the premium is paid as cash (strong altruists) are willing to pay a 42.5% premium. Finally, those who are indifferent to how the premium is spent by the recipient (warm-glow givers) are willing to pay only a 19.2% premium. We discuss the implications of our results and future research directions.     

An analysis of the demand for skill in a growing economy

We construct a trade theoretic model of skill formation with skill as a produced intermediate input. Capital is required for production as well as for education which transforms unskilled labor into skilled. We use this model to reflect analytically on India's rising requirement of skilled manpower. We show that even if growth of capital and supply of skilled manpower match, relative stagnation of unskilled manufacturing sector will magnify the gap between growth in demand and supply of skill. This may happen, for example, if there is a vast pool of workforce who may not have even the basic education to qualify as “unskilled” and excessive capital flows into the skilled sector. Thus a country with lack of education at a very basic level will be forced to import skilled manpower from the rest of the world.

Can Growth Ease Class Conflict?

This paper proposes a theory that links labor supply to wage growth and economic growth, and the conflict of interest between capital and labor. During the early stages of industrialization of a country, "surplus" labor drawn from the traditional sector of the economy is available to the modern capitalist sector at a constant or only slowly rising wage. As industrialization proceeds, this labor surplus vanishes, leading to wages rising in tandem with the growth of output. As long as there is surplus labor, workers in the modern capitalist sector, who are organized, have little interest in growth as it does not raise wages. The effect of growth is external to them, simply drawing more workers into the capitalist sector and enabling the entrants to receive rents. So capitalist-sector workers would like to redistribute income regardless of the adverse effect on growth. Once the economy grows enough for the subsistence sector to vanish, further growth raises wages. Hence, this change in the structure of the economy leads to a reduction in the intensity of the labor–capital conflict.
The dual economy model implies that growth rates rise over time and fall after the exhaustion of the labor surplus which is consistent with the stylized fact of economic growth.     

Measuring human capital in the labor market: The supply of experience in 8 OECD countries

To investigate the evolution of the supply side of the labor market, I derive a methodology to measure an important component of the human capital level of the workforce, the experience of the labor market. Based on the perpetual inventory method, a stock of experience is estimated for eight OECD countries. It appears that, during the last three decades, the OECD labor markets have faced a decline in the supply of experience by the labor market participants, with a minimum in the early 1980s for most countries and a recovery in the 1990s. Some implications regarding relative wages, relative unemployment and schooling are discussed.     

Fertility and labor supply: evidence from the One-Child Policy in China

This study provides new evidence on on the causal effect of fertility on maternal labor supply in rural China, using the fact that in some parts of rural China couples are allowed to have a second child if their firstborn is female. Estimates show that a second child reduces maternal labor force participation by 4.6 percentage points, labor supply intensity (hours worked conditional on employment) by 1.4 h per week and monthly income by 54.5 Chinese Yuan (18.7 percent). Further, the labor supply of mothers whose husbands are rural-to-urban migrants is the most sensitive to having an additional child, likely because they have more difficulty balancing farming and childcare. Conversely, labor supply is not reduced by fertility for mothers living in three-generation families, most likely because grandparents can provide both time and money to help with childcare.     

户籍管制、基本公共服务供给与城市化——基于城市特征与流动人口监测数据的经验分析

本文在理论分析户籍管制、基本公共服务供给对城市化影响的基础上，利用2015年240个城市特征数据与2016年流动人口监测微观数据进行了实证检验。研究结果显示，户籍管制抑制了流动人口迁移的稳定性与完整性，是城市选择性吸纳高禀赋人口的重要制度工具。提高基本公共服务供给有助于促进流动人口自身稳定与家庭完整迁移，但基本公共服务的正向作用不足以抵消户籍管制的负向影响。研究结果还发现户籍管制、基本公共服务供给对流动人口迁移稳定性与完整性的影响存在个体差异。户籍管制制约了新生代流动人口迁移的稳定性与完整性，增加基本公共服务供给则有利于新生代流动人口与高禀赋人口的稳定与完整迁移。     

Indeterminacy, underground activities and tax evasion

This paper introduces underground activities and tax evasion into a one-sector dynamic general equilibrium model with aggregate external effects. The model presents a novel mechanism driving the self-fulfilling prophecies, which is characterized by well behaved (downward sloping) labor demand schedules. This mechanism differs from the customary one, and it is complementary to it. Compared to traditional labor market income, the income derived from underground labor activity is subject to a lower expected tax rate when considering both the probability of detection and the evasion penalty. During a belief-driven expansion, the household allocates more time to both traditional and underground labor supply. In equilibrium, this action serves to lower the effective labor tax rate faced by the household, thus providing stimulus to aggregate labor supply so as to make the initial expansion self-fulfilling. The mechanism here is akin to a “regressive tax”; the household's effective tax rate depends negatively on the level of total labor income. We argue that an underground sector, and the associated tax evasion, offer a good economic rationale for a regressive tax rate.
