社会网络与民工工资：来自中国的证据

 本文基于来自中国22个省的农户调查数据研究了利用的不同社会网络对于不同的民工在城市劳动力市场上的工资水平的影响,结果发现：并不是利用所有的社会网络都能够提高所有民工的工资水平。首先,只有利用亲友关系找到的工作才能够得到更高的工资;其次,即使亲友关系也不能提高利用它找到工作的所有民工的工资水平,而只能显著提高女性和已婚民工的工资水平。所以,在研究中忽略社会网络和民工的差异性会导致错误的研究结论。本文有助于帮助理解中国的劳动力流动及社会网络在劳动力市场中的作用。     

产业转型升级背景下的新生代农民工失业和离职——基于就业能力的分析框架

当前,新生代农民工与城市各个产业尤其是制造业有机相连,成为城市社会生活不可或缺的一部分。然而,随着国内产业转型升级的不断推进,许多企业和众多新生代农民工都面临用工与就业的严峻考验。对于新生代农民工而言,就业能力是决定其就业的核心与本质问题。文章采用Fugate(2004)对就业能力的划分,从职业认同、个人适应性、人力和社会资本分析新生代农民工就业能力的现状。在此基础上,提出新生代农民工失业和离职问题的分析框架:就业能力无法满足市场和用人单位的需求导致新生代农民工失业;就业能力虽满足市场和用人单位的需求,但由于企业无法满足其基本诉求,导致新生代农民工离职频繁。基于此,提出对未实现就业的新生代农民工,应通过政府政策支持和新民工自我管理,提升其就业能力,进而实现就业;对已实现就业的新民工,应建立组织支持契合,积极开展指导关系项目,降低其离职倾向,在实现稳定就业的基础上实现优质就业。     

我国农民工劳动合约签订率低的原因分析——基于劳动力市场分割和产业分割的分析框架

劳动合约签订是劳动保护的重要形式,但我国农民工劳动合约签订率却只是在2008年《劳动合同法》实施后有暂时较大幅度的上扬,此后随时间推移却几近停滞。文章以劳动力市场分割和产业分割框架为基础,构建了不同劳动力市场特征和产业组织特征组合的四象限分析框架,探讨了不同象限中劳动合约的运行机制,并结合我国边缘产业和农民工现状,就劳动合约签订问题建立了一个简单的博弈模型。分析得出,在边缘产业与次级劳动力市场的组合下,农民工劳动合约签订存在着"组织失灵"、"市场失灵"和"政府失灵"三重困境,这是我国农民工劳动合同签约率停滞不前的主要原因。文章最后提出了相应的结论和政策建议。     

Fluctuations in Unemployment and Industry Labor Markets

Throughout the 1990s, and particularly in the mid- to late-1990s, the Japanese employment situation went from bad to worse. We investigate the causes of rising unemployment in Japan, using data on individual workers from the “Special Survey of the Labor Force” between 1988 and 1999. This research focuses on the effect of labor market segmentation by industry on labor flows. Our findings reveal that unemployment in the construction industry and, more recently, in the service industry has contributed greatly to the national unemployment rate. We also find that most successful job transfers occur within the same industry, even though workers may experience some periods of unemployment. Finally, our results show that labor market conditions in each industry affect the probability that a worker will fall into unemployment as well as the probability that an unemployed worker will find new employment. These findings suggest that the Japanese labor market is segmented by industry and this segmentation contributed to the worsening unemployment in Japan. J. Japan. Int.

Wage increases, wage convergence, and the Lewis turning point in China

We examine the wage trends of ordinary workers and the wage convergence between unskilled and skilled workers in China. First, we find that wages in all non-agricultural sectors, wages of migrant workers, and wages of hired workers in the agricultural sector have increased dramatically since 2003. Second, through comparing wage differentials between migrant and urban resident workers and between heterogeneous education groups within migrant workers, and by investigating the changes in the contribution of the returns to education to wage differentials, we find that the wages of unskilled and skilled workers have converged. Both the increasing wage trends and wage convergence are interpreted as evidence supporting the hypothesis that China has passed what can be called the Lewis turning point in the industrial sector. We conclude that the sustainability of economic growth in China requires an upgrading of labor market institutions to accommodate the merging of the rural and urban labor forces.     

Offshoring,wages, and heterogeneity

Considering heterogeneous responses by skill group to material and service offshoring, we examine the relationship between offshoring and the individual wages of workers in the U.S. labor market. We find that offshoring has been beneficial for high-skill workers but detrimental for middle- and low-skill workers. In particular, service offshoring, which has been widespread since 2000, has severely affected the labor market, compared to material offshoring.     

最低工资制在完全与不完全市场中的影响——一个理论分析框架

本文通过构建一个包含产品市场和劳动力市场的模型,分析了最低工资制度在社会、经济等方面的影响,并得出以下结论:如果企业是市场工资率的被动接受者,则推行最低工资制度在促进劳动者福利提升的同时,会以减损社会总福利为代价,同时社会总产出水平下降;如果企业对市场工资率有影响能力,则通过最低工资制度提高就业者工资率水平,这不仅会促进劳动者福利的提升,同时也会造成社会总福利的改进,社会总产出水平上升。以此为基础,结合当前中国的社会实际,对于最低工资制度的实施提供了相关的政策建议。     

Do E‐verify mandates improve labor market outcomes of low‐skilled native and legal immigrant workers?

We examine the impact of the 2007 Legal Arizona Workers Act (LAWA) on employment outcomes of low‐skilled legal workers. We use the synthetic control method to select a group of states against which the labor market trends of Arizona can be compared. Our results suggest that contrary to its intent, LAWA does not appear to have improved labor market outcomes of legal low‐skilled workers who compete with unauthorized immigrants, the target of the legislation. In fact, we find some evidence of diminished employment and increased unemployment among legal low‐skilled workers in Arizona. These findings are concentrated on the largest demographic group of workers—non‐Hispanic white men. While they are less likely to find employment, those who do have on average higher earnings as a result of LAWA. The pattern of results points to both labor supply and labor demand contractions due to LAWA, with labor supply dominating in terms of magnitude.     

Wages and the Composition of Experience

This paper provides evidence on the relation between alternative forms of experience and wages using data drawn from the National Longitudinal Survey of Youth. Prior labor market experience is segmented into mutually exclusive categories based on industry and occupation to examine how subsequent employers value skills acquired on previous jobs. We find that most forms of experience, including tenure at the current job, provide a comparable return. However, the wage return to prior experience in a different occupation and industry is significantly lower. Such “career changes” constitute over half of all prior work experience among workers in their mid-30s.     

The value-added tax reform and labor market outcomes: Firm-level evidence from China

The tax incentives designed to stimulate firm investment may have a large and unexpected impact on labor market outcomes. Using a comprehensive data set on Chinese manufacturing firms during the period 1998–2007 with a difference-in-differences approach, we examine the impact of the value-added tax reform in 2004 on the firm-level labor market outcomes. We find that firms in eligible industries and pilot regions (treated firms) enjoying lower costs of purchasing fixed assets under the reform tended to increase capital investment and reduce employment simultaneously relative to firms that did not have tax incentives (the control firms). Compared with the control firms, the treated firms became more capital intensive but had declines in labor share in value added and average wage. We also find that the employment adjustment is associated with increase in the share of skilled workers in terms of engineers and technicians, but not workers with a college degree or higher.     

Migrants and urban wage: Evidence from China's internal migration

Using China's 2005 1% population survey, this paper examines the wage impact on urban workers of rural to urban migration. We find that, on average, migrants increase the wages of urban workers, with the effect being magnified for more skilled urban workers. This suggests that migrants with skills similar to those of urban workers may complement them. We explore the possible channels of these effects. From the supply perspective, we find that migration inflows accelerate the occupational upgrading of urban workers, especially for low- and medium-skilled workers. From a demand perspective, as the share of migrants in the urban labor force increases, the number and output of industrial firms also increase, and firms become more reliant on low-skilled workers. The more migrants in a city, the greater the available employees for industrial firms, particularly for low-skilled employees. However, the effects on high-skilled firms are much smaller or insignificant. In addition, we find that migrants have little impact on firms' capital-labor and capital-output ratios. This suggests that firms can expand through capital adjustments to absorb inexpensive migrants, which alleviates the possible negative impact of migrants on the urban labor market.     

Wage differentials between urban and rural-urban migrant workers in China

Since the end of the 1980s, the number of migrants working in the urban labor market has increased dramatically. However, migrant workers are treated differently from urban workers. In this paper we examine the labor market discrimination against rural migrants from the point of view of wage differentials using CHIP-2007 data. We apply Jann pooled method to deal with index number problem and use Heckman two step model to correct selection problem when decomposing the wage gap. The decomposition results show that a significant difference in wage gains persists between the two groups as late as 2007. In 2007 migrants only earned 49% of urban workers' income and 17% of the wage gap cannot be explained by observed factors. In detail, differences in educational attainment, work experience and distribution across industry, occupation, and ownership of enterprises account for most of the explained wage gap.     

Females,the elderly,and also males: Demographic aging and macroeconomy in Japan

The speed and magnitude of ongoing demographic aging in Japan are unprecedented. A rapid decline in the labor force and a rising fiscal burden to finance social security expenditures could hamper growth over a prolonged period. We build a dynamic general equilibrium model populated by overlapping generations of males and females who differ in participation rate, employment type and labor productivity as well as life expectancy. We study how changes in the labor market over the coming decades will affect the transition path of the economy and fiscal situation of Japan. We find that a rise in the labor supply of females and the elderly of both genders in an extensive margin and in labor productivity can significantly mitigate effects of demographic aging on the macroeconomy and reduce fiscal pressures, despite their negative effects on equilibrium wages during the transition. The study suggests that a combination of policies that remove obstacles hindering labor supply and that enhance a more efficient allocation of male and female workers of all age groups will be critical to keeping government deficit under control and raising income across the nation.     

Economic Status and Social Attitudes of Migrant Workers in China

Migrant workers, meaning those who used to be farmers but have left rural areas and found jobs in cities as a result of economic reform and rapid development in China, have made a significant contribution to the burgeoning labor market and played an important role in speeding up the transition from a planned to a market economy. This present paper considers the economic status and social attitudes of migrant workers. It is based on the analysis of a large‐scale survey in 2006, which was conducted using questionnaires and covered 28 provinces, municipalities and autonomous regions throughout the country. It was found that the income status of migrant workers depends heavily on the education and technical skills that they have developed, rather than on identity‐based discrimination. Surprisingly, it was also found that those on less income and of lower economic and social status show more positive attitudes to society than those who are affluent and considered of higher social status. It is concluded that the decisive factor in attitude and behavior of migrant workers is historic rather than economic.     

Why is the gender earnings gap greater in Korea than in the United States?

It has long been recognized that the gender earnings gap varies across countries. This paper examines the relatively higher gender earnings gap found in the Korean labor market compared to the US labor market. Using the data set representative of the population for both countries, I found that the significant part of the differences in the gender earnings gap simply arise from the differences in the observed characteristics of women among two countries. In particular, relatively lower labor market experience, current job tenure, and educational attainment by Korean female workers play dominant roles in explaining the observed higher earnings gap. In addition, wage structure and labor market discrimination seem to be against Korean female workers compared to US female workers. J. Japanese Int. Economies 21 (4) (2007) 455–469.     

On labor incentives and work norm in Japanese firms

In this paper, we argue that social/corporate norms play an important role in achieving higher productivity and better economic welfare. We define “social norm” to be a standard of behavior suggested by a social custom, i.e., a customary choice of actions in each social situation. We reinterpret the well-known Nash equilibrium as a “norm equilibrium.” A norm equilibrium is a stable social norm, stable in the sense that there is no incentive to deviate from the behavior suggested by the prevailing social norm. This interpretation requires less information than the traditional interpretation. Moreover, we need not be concerned with the problem of refinement because it is the social norm itself which refines the equilibria. We apply this concept to the labor market. The key assumption is that the level of an individual worker's effort is private information known to workers as a whole; i.e., all workers' efforts are known to their fellow workers as well as to the workers themselves. We show that different work norms may emerge in different corporations at an equilibrium. In “prestigious” firms cooperation is the prevailing work norm, while in “nonprestigious” firms noncooperation is the norm. Thus, the efficiency wage hypothesis holds without the existence of unemployment. Some implications of this interpretation for the Japanese labor markets are discussed.     

TFP growth slowdown and the Japanese labor market in the 1990s

Unemployment in Japan nearly tripled during the 1990s. Underlying this upsurge lie an increase in the probability of workers to lose their jobs and a decrease in the probability that the unemployed find jobs. This paper analyzes the sources responsible for these labor market changes in Japan in the decade of the 1990s. We build, calibrate, and simulate a neo-classical growth model with search frictions in the labor market. Using actual TFP data, the model is able to reproduce the path of unemployment and the job flows, as well as that of output. We find it to be the decrease in productivity, coupled with the reduction in hours worked, which curtails the profits of firms, inducing a drop in employment and an increase in unemployment.     

我国劳动管理体制的演变及走势分析

随着社会主义市场经济的不断改革,劳动力市场的逐步形成、建立和日趋成熟、完善,中国提高竞争力的关键就在于企业素质的加强、提升与政府职能的转变。以中国改革开放以来经济社会转型为背景,阐述了经济转型期我国劳动劳动管理体制的演变过程和特征;以及逐步打破旧的劳动管理框架,探讨结合企业、劳动者以及政府三方协调的劳动管理体制的趋势。     

我国民营企业劳资关系新探

企业作为市场经济条件下协调劳动关系的主体,对改善劳资关系和完善劳动力市场起着极其重要的作用,而在企业的利益共同体中,劳资双方的统一与合作是绝对的,对立与冲突是相对的。本文从"经济人"和"社会人"视角对劳资关系的对立统一思想进行了理论探源。在现实新探方面,以制造业为例阐述了劳动力的低成本优势,并且认为农民工才是劳资冲突中的特殊群体。同时,劳动力的正外部性对持续性供给的冲击,加剧了我国当前的民工荒现象。为解决紧张的劳资关系,企业应承担相应的社会责任,良好的企业信誉将形成巨大的无形资产,增强其持续发展能力。
