Interpreting Wage Gaps of Disabled Men: The Roles of Productivity and of Discrimination

Using the UK Labour Force Survey, we study wage gaps for disabled men after the introduction of the Disability Discrimination Act. We estimate wage gaps at the mean and at different quantiles of the wage distribution and decompose them into a part explained by differences in workers' and job characteristics, a part that can be ascribed to health‐related reduced productivity, and a residual part. The large original wage gaps reduce substantially when we control for differences in education and occupation, although significant residuals remain. However, when we isolate productivity differences between disabled and nondisabled workers, the residual wage gap becomes insignificant in most cases.     

A Case of Sticky Floors: Gender Wage Differentials in Thailand

Using 2004 Household Socio‐Economic Survey data for Thailand, we explore the gender wage differentials across the entire unconditional wage distribution and find a strong sticky floor effect. Glass ceilings, although observed along with sticky floors in the raw data and pooled regressions, disappear in the counterfactual decompositions, suggesting a strong sticky floor pattern in gender wage differentials in Thailand. Whereas the evidence for most European countries points to glass ceilings, our findings for Thailand are qualitatively similar to those from other South Asian and Southeast Asian countries for which evidence exists; namely, Singapore, the Philippines and Sri Lanka.     

Prostitutes,Pimps, and Brothels: Intermediaries,Information, and Market Structure in Prostitution Markets

Prostitution is a multi‐billion dollar, globally distributed, low‐concentration service industry that is receiving increasing attention in the economics literature. This article focuses on a widespread, but little studied, feature of this environment—the role of intermediaries (pimps or brothel owners) on market outcomes. Prostitution laws and markets are perhaps unique in that transactions between principals (prostitutes and johns) are legal in many countries, while intermediary activity (pimping) is illegal. After surveying the varying cross‐country legality of agents we develop a simple theoretical model to analyze how the presence or absence of intermediaries shifts the distribution of market surplus. We show that eliminating pimps and brothels may shift surplus in non‐obvious ways, depending on the precise function they perform and on whether equilibrium is pooling or separating across “high quality” and “low quality” market segments. The implications of alternative policy regimes (intermediaries legal or illegal) are considered.     

二元结构下我国城镇劳动力市场中的性别工资差异研究

文章利用CHIP2002和CHIP2013数据,采用基于RIF无条件分位数回归的分解法,比较了不同时间维度和不同分位数水平上,我国农民工和城镇职工的性别工资差距及其形成机理。研究结果表明：第一,我国城镇劳动力市场中的性别工资差距不断扩大,其中农民工的性别工资差距全方位扩大,且低分位数上的增速最快,致使2013年其各分位数上的性别工资差距超过城镇职工。其中,低收入城镇职工与中等收入农民工群体的性别工资差距及其来源具有相似特征。第二,系数效应是造成城镇职工和农民工性别工资差异的主要因素,两个群体的性别歧视均有所增强。但与城镇职工相比,农民工群体的性别歧视较大且增速较快。由于低收入群体中性别歧视的快速增长,城镇劳动力市场中遭受性别歧视最严重的群体由2002年的高收入的城镇女性职工和高收入的女性农民工,转变为2013年中等收入的女性农民工和低收入的城镇女性职工。第三,尽管针对中高收入城镇女性职工的市场前歧视和市场歧视均有所弱化,但低收入的城镇女性人力资本水平及其回报率仍低于同类男性,呈现与女性农民工相似的特点。上述结果意味着,城镇劳动力市场中不同户籍、不同收入水平的女性,遭受着不同程度的性别歧视,应针对不同群体采用差别化的性别干预政策。     

The Link Between CEO Compensation and Firm Performance: Does Simultaneity Matter?

In order to combat the principle-agent problem, directors of public companies use incentive-based contracts to align the interests of CEOs and shareholders. Some studies suggest that these contracts are an inefficient use of resources, and that they do not motivate CEOs to do what is best for the firm. In this study, the author estimates a regression to find the relationship between CEO Compensation and market value of a firm. In order to address persistence, endogeneity and firm-specific effects the author uses the first-differenced and system GMM regression techniques first used by [Arellano, M.; Bover, O. “Another Look at the Instrumental-Variable Estimation of Error-Component Models,” Journal of Econometrics, 68, 1995, pp. 29–51] and [Blundell, R. W.; Bonds, S. R. “Initial Conditions and Moment Restrictions in Dynamic Panel Data Models,” Journal of Econometrics, 87, 1998, pp. 115–43; Blundell, R. W.; Bond, S. R., Windmeijer, F. “Estimation in Dynamic Panel Data Models: Improving on the Performance of the Standard GMM Estimators,” Institute for Fiscal Studies Working Paper W00/12, London, England, 2000]. These regressions report a positive relationship between CEO compensation and market value of a firm. This study concludes that incentive based contracts are effective, due to the positive pay-to-performance link, when controlling for simultaneity.

The Effect of Peer and Professor Gender on College Student Performance

The effects of peer and professor gender on student performance have been examined separately but not in conjunction. We augment previous research by including peer and professor gender, as well as their interaction, in estimations of student performance. After controlling for both student and faculty fixed effects we find that female students typically perform better than males, but this performance gap varies depending on the gender of the professor and of the classroom. Overall the effect of professor gender on student performance is small at best if classrooms are predominantly female and much larger if classrooms are predominantly male.     

Central Bank Independence,Wage Bargaining,and Labor Market Performance: New Evidence

Using data on 20 industrial countries over the period 1982 to 2003, this article finds central bank independence to favorably affect both unemployment and employment rates. The size of these effects appears to be substantial, particularly in the long term. In contrast to some of the previous literature, the article finds that the favorable effects of central bank independence do not depend on the degree of wage bargaining centralization or coordination. Furthermore, it finds that higher centralization as well as higher coordination of wage bargaining may also have favorable direct effects on labor market performance.     

The Wage Elasticity of Informal Care Supply: Evidence from the Health and Retirement Study

This article focuses on the wage elasticity of informal care supply to elderly parents employing an instrumental variable approach to account for the fact that the wage rate is likely to be correlated with omitted variables. Using the 1998 wave of the 1998 ), the wage elasticity of informal care supply is estimated to be negative and larger in magnitude than found previously. The lower bound of this elasticity is estimated to be ?1.8 for males and ?3.6 for females. Additional findings suggest that this wage elasticity differs by the type of care provided to elderly parents and that it is larger in magnitude among individuals with siblings and those with independently living parents. Overall the reductions in the informal care constitute about 18% of the labor supply response for men and about 56% of the labor supply response for women, which are not compensated by monetary transfers.     

Technological Change,Job Risk,and Wage Premium: Evidence from Taiwan

The paper reports the results of analyzing the effects of technological change and job risk on wage premiums in Taiwan. Using unique individual data combined with industry‐level indices of technological change and fatality rates across industries, the empirical results show that, overall, industries characterized by a higher rate of technological change or fatality pay a higher wage. However, these positive correlations are attributed to the sorting effect in which workers with some specific features choose to find jobs in industries with rapid technological change and higher job risk. Furthermore, this paper reports a positive relationship between education and wages after controlling for individual heterogeneity, showing the existence of education premium in Taiwan.     

Export Activity,Firm Size and Wage Structure: Evidence from Taiwanese Manufacturing Firms*

This study adopts a semiparametric smooth coefficient model to evaluate the export–wage premiums, firm size–wage premiums, and the wage gap between skilled and unskilled labor. Particular focus is placed upon widespread evidence indicating that pay levels in ‘large’ and ‘export‐oriented’ firms are higher than in their ‘small’ and ‘domestic‐oriented’ counterparts. Applying the firm‐level data for Taiwanese manufacturing firms, we find a positive export–wage premium for skilled workers and a negative export–wage premium for unskilled workers. The hypothesis of a constant export premium across firm size is rejected. While most of the export–wage premiums for skilled labor can be attributed to the small and medium firms, the large exporting firms have a significant adverse effect on wages for unskilled labor. Moreover, our results suggest that the firm size–wage premiums for skilled workers are larger than those for unskilled workers. The wage gap between the two skill groups is also sensitive to size categories.     

Gender Effect in Explaining Mobility Patterns in the Labor Market: A Case Study of Turkey

This paper examines the importance of gender for different job mobility patterns using an extensive household survey data from İzmir, the third largest city in Turkey. The determinants of job‐to‐job and job‐to‐nonemployment transitions are analyzed with the help of a multinomial logit estimation method. The results indicate that there is a distinction regarding the probability of job mobility patterns based on gender. It is more likely for women to be engaged in job‐to‐nonemployment transition, whereas men tend to change jobs more often. Although gender plays a significant role in job mobility patterns, traditionally imposed social constraints associated with childcare and household duties provide us with mixed results considering the behavior of women in the job market. On the other hand, having highly paid and secure jobs decreases the probability of both patterns of job mobility.     

Unionization,Unemployment, and Growth in Korea: A Cointegration Approach

Thanks to numerous empirical research studies, a general consensus has been reached on the effects of labor unionization on the economy such as unemployment and economic growth (GDP). However, most of the previous research examines the effects of labor unionization on the U.S. and U.K. labor markets using multiple regression models. By applying different statistical tools (multivariate cointegration analysis and vector error correction model) to Korean data, this paper finds: (1) there is a long-run equilibrium linkage among unionization, unemployment and economic growth; and (2) unionization unidirectionally and significantly Granger-causes unemployment and economic growth.     

Wage Structure Effects of Taiwan's Science and Technology Development Policy*

This article extends the demand shift analysis of Katz and Murphy (1992) to examine the impact of Taiwan's science and technology development policy on the wage structure between 1979 and 1998. Changes in factor demand are required to account for changes in the wage structure throughout this time. Decomposing factor demand shifts by industry reveal that for men with a vocational college education, the policy can account for 30 percent of the increase in demand; for a university qualification, the amount is 20 percent. It is argued that the policy effect was mostly exogenous.

The Chinese State Enterprise Sector: Labour Market Reform and the Impact on Male–Female Wage Structure

The paper examines the wage structure in the Chinese state enterprise sector between 1981 and 1987. This period is of particular interest given the introduction of major labour market reforms in China during the early 1980s. In essence the reforms represented a movement away from administratively determined prices towards a market–oriented system combined with a relatively flexible system of labour allocation. The Juhn, Murphy and Pierce (1991) decomposition is employed to shed light on the role of changing labour market institutions over the period.

The Effect of Social Security Contributions on Coverage and Wages: A Gender Perspective Using a Natural Experiment from Colombia

This article investigates, from a gender and marital status perspective, the effects of pension and health care contributions on the employment and wages of workers covered by social security regulations. To do this, I use as a natural experiment a reform implemented in Colombia during the mid‐1990. In particular I employ a differences‐in‐differences estimation based on an endogenous switching‐regression model that accounts for self‐selection into coverage. My results indicate that, for females, a 10% increase in contributions reduces the relative wages of covered workers by 7.2%. On the other hand, for males, the reform increases the relative wages of covered workers by 7.1%. Among females, the effect is predominantly present in single women. Among men, divorced and widowed workers are the only group not to experience an effect on earnings. For most family groups, the social security reform has no significant effect on coverage.     

Sexual Identity,Same‐Sex Relationships,and Labour Market Dynamics: New Evidence from Longitudinal Data in Australia

Using newly collected data on sexual identity from the Household, Income and Labour Dynamics in Australia Survey, this study examines the relationship between sexual identity and labour market outcomes. Our findings show that gay males are: (i) less likely to be continuously employed than their heterosexual counterparts, and (ii) face an annual earnings penalty of 16–21%. There are also important differences in earnings dynamics for men who transition into (or out of) same‐sex versus opposite‐sex live‐in relationships. Individual fixed effects estimates show that opposite‐sex partnerships are associated with increased earnings for men, while same‐sex partnerships are associated with small declines in earnings that are statistically indistinguishable from zero. For women, we find evidence of an earnings premium for lesbians, driven largely by increased labour supply on the intensive margin.
