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.     

Inequality of Opportunity in China's Labor Earnings: The Gender Dimension

This paper investigates the inequality of opportunity in China's labor earnings, defined as the component of inequality determined by personal circumstances that lie beyond the control of an individual, of which gender is one, as opposed to the component determined by personal efforts. Using the Survey of Women's Social Status in China (2010), we measure the share of inequality of opportunity in the total inequality of individual labor earnings for people aged 26–55 years, and separately for six birth cohorts and for female and male subsamples. Gender is revealed as the single most important circumstance determining nationwide individual labor earnings, with one's region of residence, father's occupation, father's education, birth cohort and holding rural or urban hukou also playing significant roles. A further investigation into the roles of circumstances and personal efforts (including education level, occupation, Communist Party membership, migration and marital status) confirms that circumstances play an alarmingly high role in shaping labor earnings distribution in China, and reveals notable gender differences that cannot be attributed to personal effort alone. These results provide the basis for recommending ways to improve gender equality of opportunity in the future.     

Gender Discrimination and Worker Selectivity: A Comparison of the Self-employed and Wage Earners

This study compares the size and nature of the gender earnings differentials for the self-employed and wage earners in Korea, taking into account the workers’ self-selection of each employment type. The two-stage estimates of the earnings equation, corrected for worker selectivity, are used to decompose the gender earnings differentials into productivity-related and discriminatory factors. Our results suggest that the size of the gender earnings gap is larger in the wage sector than in the self-employment sector, but not by large margin, and so is the discrimination effect when not controlled for worker selectivity. With worker selectivity controlled, the discrimination effect is greatly intensified in the wage sector, while it becomes not significant in the self-employment sector. These findings imply that the observed gender earnings gap in the wage sector is largely ascribed to discrimination against women, while the gender earnings gap in the self-employment sector is mostly due to productivity difference that, in part, is caused by worker selectivity.     

Inequality and Determinants of Earnings in Malaysia, 1984–1997*

Using three large nationally‐representative Malaysian Household Income Surveys from 1984, 1989 and 1997, the present paper examines inequality and determinants of earnings. During the period 1984–1997, Malaysia's real per capita GDP increased by approximately 70percent, the participation rates for both men and women went up among all age groups, and the average number of years of schooling increased by 1.2years. There was a significant relative wage improvement among the bottom deciles. The rate of return to an additional year of schooling remained high (at 10percent), despite the huge increase in the supply of the highly educated. The stable overall rate, however, masks an increased rate of return on women's education, and a decreased rate for men. Wage discrimination against women amounts to 16–20percent, and the bias has increased in 1997. The pro‐Chinese earning ethnic bias is estimated at 31percent.     

Do men and women discriminate against women for the same reason? Evidence from China

In this study, we examine whether men and women form gender discrimination for the same reason. To do that, we build an experimental Chinese labor market in which employers evaluate the productivity of workers who perform a real-effort task. Before evaluation, the employer observes the worker’s personal and group information. The personal information contains gender identity and a signal of productivity. The group information reveals the productivity distributions of some other male and female workers who do not differ in average productivity. However, it shows more male workers at the very top productivity levels and more female workers at the very bottom productivity levels in one treatment than in the other. According to the belief-based theory, there will be a greater degree of discrimination against female workers in the former. We find that, however, only male employers’ evaluations are well predicted by this approach. Female employers behave oppositely: their degree of gender discrimination is smaller in the treatment emphasizing men’s advantage in the tails of the productivity distributions. To explain female employers’ evaluations, we adopt the preference-based approach. Our findings suggest that employers of different genders can have different motivations for gender discrimination, and thus call attention to the theoretical foundation of gender discrimination and policy measures aimed at reducing gender discrimination.     

Gender earnings gap among the youth in Malawi

While young women's engagement in economic activities is an essential component of development, gender gaps are still commonly observed worldwide and especially in developing countries like Malawi. This study introduces recent data to provide new evidence for a sub‐Saharan country that has yet been closely examined. Using the International Labour Organization's School‐to‐Work Transition Survey (ILO SWTS) individual‐level data, I examine the gender earnings gap among the youth in Malawi by conducting Mincer earnings regressions with Heckman selection correction and applying Blinder–Oaxaca decomposition methods. I find that young women in Malawi earn significantly less than young men and that women are significantly less likely to engage in income‐generating work activities. Also, substantial unadjusted gender earnings difference in Malawi is overwhelmingly due to differences in returns. Moreover, detailed decomposition results show that gender differences in work‐related individual characteristics and firm characteristics also contribute to the gender earnings gap. The results suggest that any effort to reduce the gender earnings gap should involve improved access to education as well as better workplaces for women.     

Do Exporting Firms Pay Higher Wages? Evidence from Kenya's Manufacturing Sector

Abstract: When trade liberalization was first embarked on in Kenya some 20 years ago, a key argument against it was that it would reduce domestic wages, as exporting firms sought to remain competitive versus, for example, the low‐cost Asian countries. A counter argument was that manufactured exports require more elaborate design, supervision, packaging and handling, and thus a more educated labor force than production for the domestic market. To attract such skills, exporting firms would need to pay higher wages than non‐exporting ones. This paper uses data from Kenyan manufacturing to study the impact of trade liberalization on earnings, distinguishing between exporting and non‐exporting firms. In particular, it investigates whether exporting firms paid a wage‐premium to their employees. The study uses manufacturing firm survey data from a World Bank regional project. The study has three important findings: (1) There was a large and significant effect of exporting on wages in the first decade of trade liberalization. During the first half of the 1990s, workers in exporting firms earned up to 30 percent more than those engaged in non‐exporting firms. The results are robust even after controlling for individual and firm‐level characteristics such as employee demographics, productivity, firm location and occupation. (2) After a decade of trade liberalization, exporting ceased to be a significant determinant of wages in Kenyan manufacturing, after controlling for productivity and firm location. (3) During the 2000s, casual or irregular employment became a more common feature of exporting firms. The results suggest that while higher wages were important in attracting skilled labor to exporting firms at the beginning of trade liberalization in the 1990s, domestic competition has since reduced the wage premium. Cost cutting pressures are instead reflected in the substitution of casual and low wage labor for permanent and better educated labor and in increased automation.     

Who is Better Off from Trade Liberalization? An Experience from Urban China*

Empirical studies have found that the skill wage gap (difference between wages earned by skilled and unskilled workers) narrowed in the case of the ‘Four Asian Dragons’ as they underwent trade liberalization during the 1960s and 1970s, whereas the gap widened in most of the Latin American countries after they liberalized their economies in the 1980s. China's integration into the world economy since 1978 has been used to explain this phenomenon, but few formal studies have been carried out in China regarding the effects of trade liberalization on the skill wage gap because of the limited availability of data. The present study uses unique household surveys conducted in ten provinces of China in 1988 and 1995 to study this issue. Results show that trade liberalization that occurred in China between 1988 and 1995 was responsible for an average increase of 28.73 yuan (approximately 20 percent of the total increase) in average monthly wages. However, trade liberalization significantly widened the urban skill wage gap in China by introducing an increase in income only for those who had 13 years or more of education (at least junior high school graduates). Interestingly, import liberalization also only benefited those who had more than 9 years of schooling; whereas export liberalization brought wage increases for people with 7–12 years of education. Finally, those with specific production skills from technical schools, rather than those with several years of general education, were mostly favored in the labor market in China between 1988 and 1995.     

Tattoos,Employment, and Labor Market Earnings: Is There a Link in the Ink?

The popularity of tattooing has increased substantially in recent years, particularly among adolescents and young adults. Moreover, tattooed images are permanent unless the individual opts for expensive, time consuming, and painful removal procedures. Given the increasing popularity of tattooing, and the permanent nature of this action, it is of interest to know whether tattooed workers are more or less likely to be employed and, conditional on employment, if they receive wages that are different from the wages of their non‐tattooed peers. To investigate these questions, we analyze two large data sets—from the United States and Australia—with measures of tattoo status, employment, earnings, and other pertinent variables. Regardless of country, gender, specific measures, or estimation technique, the results consistently show that having a tattoo is negatively and significantly related to employment and earnings in bivariate analyses, but the estimates become smaller and nonsignificant after controlling for human capital, occupation, behavioral choices, lifestyle factors, and other individual characteristics related to labor market outcomes. Various robustness checks confirm the stability of the core findings. These results suggest that, once differences in personal characteristics are taken into account, tattooed and non‐tattooed workers are treated similarly in the labor market. We offer suggestions for improving future surveys to enable a better understanding of the relationships between tattooed workers and their labor market outcomes.     

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.     

Influence of a Wife's Working Status on Her Husband's Accumulation of Human Capital

Japanese household‐level data consisting of husband's earnings, wife's working status and their schooling levels are used to test three hypotheses, with particular consideration given to the time‐consuming process of human capital accumulation within marriages. The empirical results supports the following hypotheses: (i) a non‐working wife's schooling has a greater positive effect on her husband's earnings than a working wife's schooling; and (ii) the effect of a non‐working wife's schooling increases with the length of marriage, whereas the effect of a working wife's schooling does not change over the course of marriage.     

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.     

Decomposition of the increase in earnings inequality in urban China: A distributional approach

This study examines changes in Chinese urban income distribution from 1987 to 1996 and 1996 to 2004 using nationwide household data and investigates the causes of these changes. The Firpo, Fortin, and Lemieux (2007, 2009) method based on unconditional quantile regressions is used to decompose changes in income distribution and income inequality measures, such as variance and a 10:90 ratio. The decomposition results show that wage structure effects, such as a widening gender earnings gap, increases in returns to college education, and increases in earnings differentials between industries, company ownership types, and regions, have been the major contributors to the overall increases in income inequality. It was also found that at different points on the income distribution (e.g., the lower or upper half), the contributing factors that increase income inequality are different.     

The impact of E‐Verify mandates on labor market outcomes

A number of states have adopted laws that require employers to use the federal government's E‐Verify program to check workers' eligibility to work legally in the United States. Using data from the Current Population Survey, this study examines whether such laws affect labor market outcomes among Mexican immigrants who are likely to be unauthorized. We find evidence that E‐Verify mandates reduce average hourly earnings among likely unauthorized male Mexican immigrants while increasing labor force participation among likely unauthorized female Mexican immigrants. Furthermore, the mandates appear to lead to better labor market outcomes among workers likely to compete with unauthorized immigrants. Employment rises among male Mexican immigrants who are naturalized citizens in states that adopt E‐Verify mandates, and earnings rise among U.S.‐born Hispanic men. There is no evidence of significant effects among U.S.‐born non‐Hispanic whites.     

Parental Education and Children's School and Work Status in Urban Ethiopia: A Note on Gender Bias

This paper examines gender bias in the parental education–child status link using data from urban Ethiopia. Gender bias is defined here, specifically, as the differential impact of a parent's education on a child's status depending on the gender of the parent vis‐à‐vis the child. Children's status is measured by school enrolment and participation in market work. Results from a basic model point to same‐gender bias – father–son, mother–daughter in school enrolment and father–son in market work. In an extended model, results show that father–son bias in market work may be particularly pertinent for middle‐ to later‐born children. Policy interventions should be mindful of such differential effects, particularly if the aim is to address persistent gender disparities in children's status.     

Input Trade Liberalization and the Export Duration of Products: Evidence from China

This paper introduces a quasi‐natural experimental framework into trade policy evaluation and reassesses China's trade liberalization through the survival of export products. We use propensity score matching and China's dual trade system to design a quasi‐natural experiment based on Chinese industrial enterprises, customs import and export, and tariff data over the period of 2000–2006; we then use survival analysis to study the impacts of China's trade liberalization on the export duration of manufacturing firms’ products. We find that the substantial reduction in import tariffs after China's accession to the World Trade Organization enhances the export duration of firm products, indicating that trade liberalization ameliorates the survival of export products. The promotion effects of tariff reduction on export duration are obviously stronger for core products than for noncore products.     

Health Status and Earnings of Migrant Workers from Rural China

The migration of rural laborers into cities for employment has been one of the main driving forces of China's economic growth over the past three decades. Based on a dataset collected by the Ministry of Agriculture of China from 2003 to 2007, this paper examines the impact of health on the earnings of migrant workers engaging in physically‐intensive work requiring good health. Our findings indicate that a poor health status not only weakens the incentive of rural laborers to participate in the migrant labor force but also significantly reduces their earnings. A migrant worker in poor health only earns 67 percent of what a healthy worker makes. Among all the human capital characteristics and family economic factors, health status is the most influential on earnings for less educated workers. Labor productivity has a greater impact on earnings than the annual number of days that a person works. Ongoing health‐care reforms aimed at the improvement of the health‐care services available to rural laborers are urged to help reduce poverty in rural China.     

户籍歧视对劳动报酬差异的影响

在我国，户籍歧视是形成劳动力市场分割的重要原因，它不但通过阻碍劳动力流动造成城乡收入差异，也会促成农民工和城镇工人之间劳动报酬的差异。本文利用中国健康与营养调查（CHNS）多年的数据，对我国户籍歧视影响劳动报酬差异的程度进行计算和分析。结论表明，近几年户籍歧视现象并没有明显改观，政府在制定相应政策时，仍需关注这方面的问题。     

生育政策、子女数量与中国的性别教育平等

近年来,中国性别教育差距快速缩小并呈现出女性高等教育在校生比重超越男性的现象,文章从生育政策视角对这一现象进行了解释,认为计划生育政策通过改善女性教育获得显著促进了性别教育平等。队列分析显示,生育政策之后的出生队列中女性相对教育水平明显提高,性别教育差距明显缩小。基于生育政策地区差异和出生队列差异构建的双差分模型分析发现,以农村二孩政策地区为参照组,严格的独生子女政策在提高女性相对受教育机会方面更为明显。但相对于二孩政策,一孩半政策在促进性别教育平等方面不存在显著差异,这可能由于在一孩半政策下独女户和双女户数量较少,家庭受性别偏好影响会将资源向男性倾斜,导致政策没有通过控制家庭规模提高女性相对教育获得机会。研究认为,随着中国放松生育政策,农村地区由一孩半政策过渡到二孩政策并不会对女性教育获得产生明显影响,应该关注生育政策调整对严格独生子女政策地区女性教育获得的影响。同时,随着性别教育差距逐步缩小,可以利用劳动力市场政策降低市场性别歧视,进一步提高女性地位并促进性别平等。     

How Do Local Labor Markets and Human Capital Affect Employment Outcomes after Job Loss?

This article uses the Longitudinal Employer‐Household Dynamics to evaluate how local industry concentration affects earnings losses for displaced workers. “Concentrated industries” are those industries with a high employment share within a labor market. This article compares earnings changes between displaced workers and job stayers within concentrated industries to the same within less concentrated industries. A separate comparison is made based on the expected level of job availability within the labor market. The findings show that earnings changes for displaced workers relative to job stayers are 7–13% higher within concentrated industries when job loss occurs during periods of high job availability. Earnings changes are 4.5–6% lower, however, when the same comparison is made during periods of low job availability. When firms are hiring workers, they are more likely to hire those previously employed within the same industry, since these workers have accumulated more relevant human capital.
