IDENTITY MANAGEMENT: WORKER INDEPENDENCE AND DISCRIMINATION AGAINST GAY MEN

I build on a growing literature documenting wage differentials for gay men by showing that the wage differential gay men experience varies significantly across occupations with different levels of worker independence. The penalty is smallest in management and professional occupations, which involve a high level of worker independence. It is largest in service occupations, which include a lower level of independence. This distribution of earnings penalties is consistent with discrimination being the source of the gay wage penalty. The results support the conjecture that higher levels of independence allow gay men to more successfully manage the disclosure of sexual orientation and mediate the negative effects of discrimination.

WAGE VOLATILITY AND CHANGING PATTERNS OF LABOR SUPPLY

Over the past few decades, the skilled–unskilled hours differential for U.S. men increased when the skill premium rose sharply, in contrast with dominant income effects. Based on PSID data, we show that over the 1967–2000 period, skilled men experienced a three times larger increase in wage volatility than unskilled men. With the rise in wage volatility, our general equilibrium incomplete markets model generates a 2.7 hours increase in the hours differential whereas it increased by 1.4 hours in the data. We find that hours adjustments are important for self‐insurance in the short run, whereas precautionary savings play a crucial role eventually.     

中国农村老人的劳动供给研究

本文利用2000年农户抽样调查数据,测算了中国农村50岁及以上人口的劳动参与率并分析了影响农村老年劳动力劳动供给的因素。研究发现,农村老人的劳动参与率较高;影响老人是否工作的因素主要是年龄、健康状况、所承担的责任、性别、居住方式和土地等家庭因素,与经济因素关系不大。分析结果表明,随着农村家庭的核心化和青壮年劳动力向城镇流迁,农村传统的家庭养老模式正面临冲击,必须在农村建立社会养老保障机制。     

MEDICAID AND THE LABOR SUPPLY OF SINGLE MOTHERS: IMPLICATIONS FOR HEALTH CARE REFORM

The Medicaid expansions and health insurance subsidies of the Affordable Care Act (ACA) change work incentives for single mothers. To evaluate the employment effects of these policies ex ante, I estimate a model of labor supply and health insurance choice exploiting variation in pre‐ACA Medicaid policies. Simulations show that single mothers increase their labor supply at the extensive and intensive margin by 12% and 7%, respectively, uninsurance rates decline by up to 40%, and an average family's welfare improves by 1,600 dollars per year. Health insurance subsidies and not Medicaid expansions mostly drive these effects.     

FACTORS AFFECTING THE LABOR SUPPLY DECISIONS OF REGISTERED NURSES

We estimate the labor force participation and the full‐time and part‐time work decisions of female registered nurses (RNs) and find higher wages are not a significant factor to (a) increase the likelihood of working nor (b) to encourage full‐time work. Another key factor is age which, given the aging of the RN population, foreshadows dwindling labor supply. This, while demand for RNs is predicted to continue to rise, will exacerbate labor shortages in the market for RNs. The results also offer insight to explain the reduction in labor supply wage elasticities for female workers in general in the United States. (JEL I11, J22, J44)     

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。     

THE EFFECTS OF THE 1978 PREGNANCY DISCRIMINATION ACT ON FEMALE LABOR SUPPLY*

This article analyzes the effects of the 1978 Pregnancy Discrimination Act (PDA) on the labor force participation rates of married women by estimating a dynamic model of labor force participation. Results show that the PDA increased the labor force participation rate of pregnant women by 8.2 percentage points, of women with a child less than one year old by 3.4 percentage points, and of women with older children by 1.5 percentage points. Counterfactual policy simulations show that the provision of unpaid leave will increase the labor force participation rate of women with older children by an additional 3.7 percentage points.     

家庭劳动供给的影响因素研究： 文献综述视角

随着招工难、用工短缺问题的持续蔓延,从微观角度特别是家庭角度来剖析劳动供给行为的基本规律,显得愈发重要。本文从家庭劳动供给的决策模式、家庭特征变量与外部环境变量的影响、家庭成员间的交互影响、公共政策的作用等五个维度梳理了国外对家庭劳动供给行为的最新研究成果,这对引导我国家庭劳动供给决策、缓解工业劳动力供求矛盾具有重要的借鉴意义。     

THE EFFECTS OF THE 1.03 MILLION YEN CEILING IN A DYNAMIC LABOR SUPPLY MODEL

In this paper I examine the effects of a means-tested transfer system in Japan ("1.03 million yen ceiling") in a dynamic labor supply model with endogenous retirement. In Japan, married women have reason to limit their annual earnings to no more than 1.03 million yen in order to receive a number of benefits available to low-income wives, and in fact often choose to do so. In a dynamic model, the optimal labor supply schedule follows a pattern that is not seen in a static framework, which I call the "spillover effect." The paper also examines the properties of dynamic welfare cost of this ceiling. ( JEL J22, H24, H55)     

新农村建设中红色文化遗产法律保护的经济学分析

文章基于公共物品私人供给的模型,构建了新农村建设时期乡村红色文化遗产保护过程中村民在个体理性支配下同集体理性进行博弈的分析框架,并据此对实践中存在的保护政策失效和村民间保护意愿差异的现象进行了解析。结论认为,村民在个体理性支配下的博弈行为符合福利经济学基本理论,构成了保护政策失效的主要原因;为此,结合村民的行为特点和福利经济学的分析,引入了法律保护机制以探求思路和对策。     

THE DIVISION OF LABOR AND ROUNDABOUT PRODUCTION: ALLYN YOUNG REVISITED

Abstract.  This paper investigates Allyn Young's two important doctrines concerning the division of labor and roundabout production. First, apart from advancing the state of knowledge, the progressive division of labor that can occur within a given population encourages the adoption of more specialized, differentiated intermediate goods in the production process. Second, the level of division of labor and the extent of the market depend on each other. Using a general equilibrium model with increasing returns to specialization, economies of complementarity between intermediate goods, and transaction costs, we demonstrate that the level of division of labor and the number of intermediate goods increase concurrently as transaction conditions are improved.     

GLOBALIZATION AND THE EVOLUTION OF THE SUPPLY CHAIN: WHO GAINS AND WHO LOSES?*

This article focuses on two distinct facets of globalization: decrease in the trade costs of goods and the decline of communication costs between headquarters and production facilities. When the unskilled have about the same wage in two regions, decrease of these costs fosters the agglomeration of plants in the core accommodating headquarters. When the wage gap is significant, process of integration eventually triggers the relocation of plants into the periphery. When this process of relocation is driven by falling communication costs, the welfare of all workers in the core falls whereas that in the periphery rises.     

INEQUALITY OF OPPORTUNITY IN EARNINGS AND CONSUMPTION EXPENDITURE: THE CASE OF INDIAN MEN

The paper associates inequality of opportunities with outcome differences that can be accounted by predetermined circumstances which lie beyond the control of an individual, such as parental education, parental occupation, caste, religion, and place of birth. The non‐parametric estimates using parental education as a measure of circumstances reveal that the opportunity share of earnings inequality in 2004–05 was 11–19 percent for urban India and 5–8 percent for rural India. The same figures for consumption expenditure inequality are 10–19 percent for urban India and 5–9 percent for rural India. The overall opportunity share estimates (parametric) of earnings inequality due to circumstances, including caste, religion, region, parental education, and parental occupation, vary from 18 to 26 percent for urban India, and from 16 to 21 percent for rural India. The overall opportunity share estimates for consumption expenditure inequality are close to the earnings inequality figures for both urban and rural areas. The analysis further finds evidence that the parental education specific opportunity share of overall earnings (and consumption expenditure) inequality is largest in urban India, but caste and geographical region also play an equally important role when rural India is considered.     

TEMPORARY EMIGRATION AND WELFARE: THE CASE OF LOW‐SKILLED LABOR

This article studies the implications of temporary emigration for the welfare of a source country. The framework is one of general equilibrium, where the economy's stocks of both capital and labor are endogenously determined by the saving and migration decisions of optimizing agents. Simulations of the model suggest that for realistic values of the parameters, welfare of nonmigrants of the source country is maximized when the migrants are employed abroad for a period in the range of roughly 8–12 years. The ideal duration is found to be an increasing function of the international wage differential, migration costs, and the degree to which the rights of migrants are protected in the host country.     

THE POLITICAL ECONOMY OF LEGAL SEGREGATION: JIM CROW AND RACIAL EMPLOYMENT PATTERNS

Legal segregation was a fact of life for blacks in the American South during the first half of the present century. These laws are sometimes compared to South African apartheid . However, there seems to be one important difference: Jim Crow, unlike apartheid , did not directly hamper the ability of blacks to compete with whites in labor markets. Our paper explores this problem. We report evidence which suggests that, in spite of the absence of direct labor market restrictions confronting blacks subject to Jim Crow, these laws nevertheless reduced the ability of blacks to compete with whites for jobs.     

公共征信机构建立的供求契机及境外实践

征信机构是重要的金融基础设施。结合若干经济现象与经济理论,本文研究表明,对于原生的建立机制而言,后工业化背景下的政府干预是一国建立公共征信机构的供给因素;金融体系的银行主导型特征为需求因素;而爆发重大经济、金融问题则是建立公共征信机构的触发点。公共征信机构是否与私营征信机构并存则主要取决于二者在市场定位、功能定位上的差异程度。当前中国坚持公共征信机构为主导的征信模式有其经济上的必然性、合理性。
