影子工资、影子收入与农户劳动供给——基于四川沐川县、安徽金寨县的调查分析

贫困地区就业的典型特征是自我雇佣,很少从事有酬劳动。如何在没有工资的情况下估计劳动供给行为就成为一个难题。在这种情况下,通过影子工资和影子收入来观察农户及其成员的劳动供给行为,为我们研究农户劳动力配置提供了一个有效的分析工具。本文利用Translog和C—D生产函数对四川省沐川县、安徽金寨县农户在林业、种植业、畜牧业和非农业的影子工资率进行估算,并利用Heckman两阶段模型分析了影子工资率等因素对农户劳动供给的影响,结果表明该地区农户的影子工资与劳动时间之间是负向关系,闲暇对于男性和女性来说是劣质品,家庭劳动供给的联合决策特征非常明显,家庭劳动力存在主次之分,该结论对于说明家庭内劳动分工以及劳动力流动有一定的指导意义。     

城市贫困群体就业扶持政策的劳动供给效应——一个基于自然实验的研究

本文将城市贫困群体就业扶持政策的实施作为一个自然实验,应用微观经济计量方法分析了城市贫困群体中女性和男性的劳动供给反应。研究结果表明,贫困群体中女性劳动供给和男性劳动供给的净工资弹性分别为3.22和1.94;就业扶持政策使贫困群体中女性劳动供给和男性劳动供给分别增加了106.47%和57.33%;贫困群体劳动供给的增加主要是由就业率上升而非工作时间增加引起的。因此,通过就业扶持政策可以有效地增加贫困人口的劳动供给,提高贫困人口收入,达到有效削减贫困的目的。     

中国城镇居民的劳动供给行为——倒S型劳动供给曲线在中国城镇劳动力市场上的实证检验

依据2002年中国家庭收入项目(CHIP)数据,本文应用微观经济计量方法估计了城镇居民的就业方程和工作时间方程。研究结果表明,随着教育年限的增加,个体就业概率不断增加;随着家庭其他收入的增加,个体就业倾向逐渐降低,工作时间逐渐减少;随着家庭人口数的增加,就业个体的工作时间逐渐增加。低收入群体女性和男性工作时间的工资弹性分别为-0.3237和-0.3167,而女性中高收入群体工作时间的工资弹性为0.1429,说明倒S型劳动供给曲线在2002年中国城镇劳动力市场是存在的。因此,政府部门应结合经济发展水平适时地提高最低工资标准,完善社会保障制度,同时加大对低收入群体教育和培训投入力度,促进低收入群体社会福利水平的改善。     

林业主产区农户影子工资对家庭劳动供给影响的实证分析

本文利用1990—2001年我国四川省沐川县、安徽省金寨县480户农户的数据,采用Translog函数和C-D生产函数对样本林业主产区农户在林业、种植业、畜牧业和非农业的影子工资进行估算,并利用Heckman两阶段模型分析了影子工资、影子收入、户主年龄、户主受教育程度、家庭负担等因素对农户劳动供给的影响。研究结果表明:样本林业主产区农户的影子工资与劳动供给时间存在负向关系,闲暇对于农户家庭中男性和女性来说是劣质品;农户家庭劳动供给的联合决策特征非常明显;农户家庭劳动力存在主次之分,该结论对于说明农户家庭内劳动分工以及劳动力流动有一定的指导意义。     

杭州都市圈经济增长问题研究——基于C-D生产函数的面板数据实证分析

基于C-D生产函数,对杭州都市圈的经济增长问题进行研究。发现杭州都市圈的总产出Y与资本投入K和劳动投入L同向变动,资本产出弹性和劳动产出弹性分别为0.77%、0.47%。尽管各年份的产出资本弹性和产出劳动弹性相同,但是产出会随着时间的推移逐渐增加,说明技术进步对经济所起的作用在逐年提高。最后证明了杭州都市圈的经济产出、资本投入和劳动投入三者是存在协整关系的,这三者在长期存在一个稳定的均衡关系。     

代际支持、女性劳动供给与中国性别工资差异收敛−基于性别分工的视角

我国"男主外、女主内"的性别分工观念年深日久,但相比世界很多国家,女性劳动参与率反而很高、性别工资差异也较低,中国文化中长期承袭着父辈对子女代际支持的传统可能是缓解女性劳动供给约束的重要动因.文章构建考虑父辈代际支持的家庭劳动供给模型,利用中国家庭追踪调查数据(CFPS),分析了父辈时间支持和经济支持对子女,特别是女性劳动力的劳动供给和工资收入的影响与机制.研究发现,父辈的时间支持明显缓解女性劳动参与的时间约束,提高其劳动供给和工资收入,但没有发现对男性有显著影响,故有利于性别工资差异收敛;而父辈的经济支持均未发现对子女的劳动参与和工资收入有显著影响.此外,对城乡进行区分后发现,父辈时间支持对城镇女性的作用比农村女性更强.文章的研究有助于加深对我国劳动力市场中女性劳动供给行为和性别工资收敛性的理解,对进一步完善劳动就业制度也有一定启示.     

谁增加了劳动时间供给？——来自CHNS的证据

文章利用微观经济理论推导出低收入者在追求效用最大化和满足最低生存必需支出的约束条件下,低工资率时劳动供给曲线将向右下方倾斜。在此基础上,利用CHNS（2006）数据对其劳动供给时间进行了实证分析并进行解释,找出了工资率下降时增加劳动供给时间的劳动者个体特征。     

新《劳动合同法》的实施对劳动力供给的影响研究

新<劳动合同法>的实施引起社会各界的广泛关注,新法对劳动力供给究竟产生何种影响,目前国内尚无此问题微观角度的实证分析.本文采用个体跨期最优模型,通过计算劳动力供给跨期弹性,分析新法对劳动力供给的影响.结果发现,在新<劳动合同法>实施后,劳动力的跨期弹性变小.新法的实施达到了建立和谐稳定的劳动关系和稳定劳动力供给的目的.     

中国公共部门劳动生产效率实证研究

借鉴Karras(2007)的实证模型,本文利用中国1988-2007年30个省、市、自治区的面板数据,对公共部门的劳动生产效率进行实证分析,结果显示:(1)中国公共部门的劳动产出弹性为0.008;(2)中国公共部门的劳动边际产出高于非公共部门;(3)中国公共部门劳动人员的显性工资存在低估。虽然中国公共部门的劳动边际产出相对于非公共部门高,但其产出弹性仍处于较低水平。本文的政策含义是:加大劳动密集型公共品供给力度,有利于提高中国整个经济的产出水平;中国非公共部门需要改变劳动力粗放投入模式,地方政府应鼓励私人部门为员工提供多元化的职业培训与技能教育,以提高其边际产出。同时,优化公务员薪酬结构,将隐性收入逐步纳入正规货币工资范围之中。     

人力资本投资对工资的影响

市场对劳动力作用的评价是工资。人力资本投资通过提高劳动素质来决定劳动市场的供给方面，从而间接决定工资水平。     

Reference Dependent Preference and Labor Supply: Evidence from China

This paper investigates the daily labor supply decisions of Hangzhou cabdrivers. We find that Hangzhou cabdrivers’ wage elasticity is significantly positive, their working decisions are largely affected by shift time, and crude proxy variables for income; hours targets can hardly explain their working behavior. Nevertheless, Hangzhou cabdrivers are still affected by reference dependent preference. Using new empirical strategies, we show that cabdrivers are more likely to continue working when wage rates are unexpectedly low and more likely to quit when wage rates are unexpectedly high.     

Do Women Have Different Labor Supply Behaviors? Evidence Based on Educational Groups in Uruguay

This study uses Uruguay’s historical fluctuation in real wages to set up a natural experiment to measure the relation between women’s labor supply and wages. Using data from the Continuous Household Surveys of the Uruguayan National Statistics Institute, for 1986–2010, it aims to identify and explain heterogeneity in the labor supply behavior of women with different educational backgrounds. It finds that all women groups seek to optimize their remunerated work allocation throughout their life cycle, although women’s labor behaviors vary depending on educational levels. The rising trend of women’s labor force participation is expected to continue; its implications at the intensive margin are ambiguous and depend on how women conciliate paid work with household responsibilities – especially women with less education. These results could inform present debates about designing public policies to facilitate women’s entry into the labor market and cater to their different wage profiles and household care demands.     

Labor and behavior determinants of remittances in Saudi Arabia

Saudi Arabia is the second largest sender of international remittances. These remittances constitute large foreign capital inflows to labor‐exporting remittee economies. This study is the first to structurally decompose remittance dynamics into behavioral and labor market outcomes of migrants. Remittance outflows are decomposed into migrant labor supply, unemployment and participation rates, wage earnings, and the marginal propensity to remit (MPR) out of migrant earnings. The estimates suggest that migrant labor supply is highly elastic. The important driver of remittance dynamics is the MPR, migrant wages, and the labor supply of migrants. The MPR is found to respond counter‐cyclically to foreign gross domestic product.     

The macroeconomics of the quiet revolution: Understanding the implications of the rise in women’s participation for economic growth and inequality

We study the impact of the rise in female labor supply on the economic performance of the United States over the period 1967–2002 through the lens of a calibrated structural model. The model features all the key forces behind the increase in female participation (the “Quiet Revolution”): (1) the decline in marriage rates, (2) the narrowing gender wage gap, (3) the preference (or cultural) shift towards market work, and (4) the change in women’s bargaining power within the household. We find that preference shifts and the rise in relative wages of women were the most important driving forces behind rising women’s participation, while changes in marriage patterns have also had a sizeable effect. We conclude that half of the growth in US earnings per capita over this period can be traced to growth in female labor supply. We also find that the rise in female labor supply has had offsetting effects on income inequality and, therefore, its overall role has been negligible relative to skill-biased demand shifts and rising residual wage volatility.     

HOUSEWORK: PRICELESS OR VALUELESS?

Two ways of estimating the value of housework are currently used. One is the opportunity cost approach, which sets the value of work done at home equal to the income the person could earn in the labor market. The other is the market cost approach, which uses the cost of hiring someone to do the housework to determine its value. In this study we use data on earnings of female clerical workers with various patterns of labor force participation to obtain estimates of the opportunity cost of hometime for such women. We find that potential market earnings do not provide an acceptable estimate of the value of housework, and suggest that using the wages of general household workers is a better approach.     

Migration and imperfect labor markets: Theory and cross-country evidence from Denmark,Germany and the UK

We investigate the labor market effects of immigration in Denmark, Germany and the UK, three countries which are characterized by considerable differences in labor market institutions and welfare states. Institutions such as collective bargaining, minimum wages, employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks, and, hence, the labor market effects of immigration. We employ a wage-setting approach which assumes that wages decline with the unemployment rate, albeit imperfectly. We find that the wage and employment effects of immigration depend on wage flexibility and the composition of the labor supply shock. In Germany immigration involves only moderate wage, but large unemployment effects, since immigrants are concentrated in labor market segments with low wage flexibility. The reverse is true for the UK and Denmark.     

Increasing dispersion of skills and rising earnings inequality

In recent decades many countries have simultaneously liberalized their trading regimes and expanded their education systems. The theoretical effect of these regime shifts on the wage differential between skilled and unskilled workers is ambiguous. On the one hand, openness to trade causes demand shifts in the labor market which may widen or narrow the differential. This result depends on whether the unskilled wage is depressed, as in the case of importing countries, or raised, as in the case of exporting countries. On the other hand, an increased supply of more educated workers reduces their wages and narrows the skill wage gap. In this study of the labor market of Hong Kong, we document that recent changes in response to the trade liberalization of Mainland China and expanded access to education have increased the earnings differential between skilled and unskilled workers. Using detailed census data, we argue that the main reason for this outcome is the widened dispersion of skills across the earnings distribution, resulting from demand and supply shifts in the labor market caused by trade openness and expanded access to higher education.     

我国工资差异变化及影响因素分析——基于家计调查的实证研究

尽管中国在经济转型过程中取得了令世人瞩目的经济增长速度,但随之而来的是不断扩大的工资收入差异和持续扩大的工资收入差距引发了广泛关注.一般认为,工资差距过大对社会公平和正义造成伤害,并直接影响中国经济和社会的可持续发展.基于家计调查数据并使用经济计量模型分析方法,本论文对中国在过去二十年日益增长的工资差距进行实证分析并探讨影响工资差距的主要因素.研究表明,政府对劳动力市场机构特别是工资政策改革是引发工资差距不断扩大的原因之一.本论文指出,劳动力市场机构的变化不是造成工资差异扩大的唯一因素;其它重要因素包括劳动力市场歧视以及制度性障碍,如中国现行的户口政策造成的劳动力市场分割等.本论文还从政策层面对减少工资差异提出建议.     

我国价格总水平决定的一个理论模型

开放经济条件下的价格总水平由产品市场、货币市场和劳动市场三个市场达到均衡状态时共同决定,影响我国价格总水平的主要因素包括货币供给量、名义工资水平、利率、汇率和资本市场发展水平。从长期来看,在其他情况不变的情况下,价格总水平随着名义货币供给量、名义工资水平、汇率以及利率的增加而上涨;推动资本市场发展对于促进价格总水平的稳定具有积极作用。     

Labor-Leisure Choice and Relative Income Concerns in the Shadow of the Housing Market

We theoretically examine the connection among labor productivity, work time, and housing costs in an economy with households differing in wages and neighborhoods differing in quality. We argue that the location rent component of housing cost is key to explicating the connection. We trace how the housing market makes relative income instrumental for maximizing utility even if households’ utility functions are not interdependent. Over time, productivity growth yields higher wages but households compete some of that away on the housing market. This structural inflation of location rents counteracts preferences to work less as wages rise and hinders the expansion of leisure. Relative income effects are shown to arise as a consequence of a market institution that monetizes socially-imbued preferences.
