Economic transition and gender differentials in wages and productivity: Evidence from Chinese manufacturing enterprises

We use firm-level data to analyze male–female wage differences in Chinese industry in the late 1990s. Our estimates indicate that employers' discrimination against women was not a significant source of the gender wage gap in Chinese state-owned enterprises. Instead, we find that the relative wage of unskilled female to male workers was higher than their relative productivity. This result indicates that unskilled female workers in the state sector had historically received wage premiums and consequently accounted for a disproportionate share of the sector's labor surplus.     

PRIVATIZATION IN CHINA: TECHNOLOGY AND GENDER IN THE MANUFACTURING SECTOR

This paper examines the impact of privatization on gender discrimination in China across firms with different technology intensities. Using a comprehensive firm‐level survey, the paper identifies gender wage‐productivity differentials by directly estimating the relative productivity levels of workers from the production function of firms. The panel structure of the survey is taken advantage of by following firms that were fully state‐owned in the initial year, and distinguishing them from firms that were later privatized. The main results show that privatization was associated with an increase in relative productivity of female workers in high technology industries, and a reduction in relative productivity of female workers in low technology industries. Time varying coefficient results suggest that the improvements in gender outcomes in high technology industries may not be maintained in the long run as the relative wage and productivity ratios tend to deteriorate, potentially due to low supply of highly educated female workers. At the same time, outcomes in privatized low technology industries increase over time, lowering the wage and productivity gaps between male and female workers. (JEL J16, J31, P20)     

THE RESPONSE OF STATE‐OWNED ENTERPRISES TO IMPORT COMPETITION: EVIDENCE FROM CHINESE MANUFACTURING FIRMS

We examine the wage and employment impact on Chinese firms of an increase in import competition associated with China's WTO accession in December 2001, with an emphasis on state‐owned enterprises (SOEs). We find that both wage and employment are negatively impacted by an increase in import competition, but firms with high state ownership cut employment less and reduce wages more than their private counterparts, suggesting that they prioritize the protection of employment over that of wages. This finding supports the notion that SOEs may have ‘multitask’ responsibilities in terms of protecting employment as well as achieving efficiency. We also find that firms with higher capital intensity reduce their wages less but cut employment more in response to intensified import competition. This provides empirical support for the efficiency wage theory.     

Sex, Wages, and Productivity: An Empirical Analysis of Israeli Firm-Level Data

Sex discrimination in labor markets may generate a wage gap between men and women that exceeds any gap in marginal productivity. We test for this type of discrimination using unique firm-level data on manufacturing firms in Israel. There is a statistically significant negative association between wages and the proportion of a firm's workforce that is female. However, there is also a statistically significant negative association between marginal productivity and the proportion of females. The difference beween the wage and productivity gaps is small relative to wage-regression estimates of wage discrimination, and is not statistically significant, which is most consistent with no discrimination.     

The impact of China's millennium labour restructuring program on firm performance and employee earnings1

Around the turn of the century, China experienced perhaps the largest labour restructuring program in the world. This paper uses a new dataset of Chinese industrial enterprises to examine what leads to downsizing, and tries to understand the effects of labour downsizing on firms’ technical efficiency, financial performance and employee wages. We find that downsizing is more prevalent in state‐owned enterprises (SOEs), and is more likely when enterprises are older, larger and have higher excess capacity. For both SOEs and private firms, downsizing is more likely when the prices of their products drop, but private firms respond more dramatically. Moreover, downsizing has serious short‐term costs in terms of total factor productivity (TFP). For mild downsizing, private firms suffer more deterioration in productivity. The distribution of surplus after downsizing is more favourable to labour in SOEs. For severe downsizing, both SOEs and private firms exhibit lower TFP growth with similar magnitudes. Our findings imply that private firms emphasize profit goals, while SOEs place a greater weight on labour protection.     

Sex Differentials in Earnings in the South Korean Labor Market

We examine gender differences in earnings among South Korean workers in 1988 – the year the South Korean National Assembly enacted the Equal Employment Opportunity Act. Using the "88 Occupational Wage Bargaining Survey on the Actual Condition," we calculate women's mean earnings as a percentage of men's mean earnings by major industrial category and educational attainment. We find a larger wage gap among clerical and sales workers than production workers or professionals. Generally, the more education a woman has, the smaller the gap between her earnings and those of her male counterparts. Women with a middle-school education have a mean income 53.5 percent that of comparable men, while the female-to-male wage ratio among college graduates is 76.1 percent. We analyze wage differences separately for women and men. Following Ronald Oaxaca's (1973) work, we decompose male–female wage differentials. We also calculate a discrimination coefficient. Our work shows that, all else equal, men earn from 33.6 percent to 46.9 percent more than women with comparable skills. We attribute the difference to gender discrimination.     

Wage differentials, discrimination and efficiency

I analyze a large labor market where homogeneous firms post wages to direct the search of workers who differ in productivity. I show that the model has a unique equilibrium. The wage differential depends positively on the workers’ productivity differential only when the latter is large. When the productivity differential is small, high-productivity workers get a lower wage than low-productivity workers. This reverse wage differential remains even when the productivity differential shrinks to zero. However, the equilibrium is socially efficient. High-productivity workers always get the employment priority and higher expected wages than low-productivity workers. Although discrimination in terms of expected wages does not exist, conventional measures are likely to incorrectly find discrimination in the model.     

Wage differentials and state‐private sector employment choice in Yugoslavia*

In this study we use the newly available Yugoslavian Labor Force Survey data to investigate wage differentials and employment decisions in the state and private sectors in Yugoslavia. For the analysis we use three empirical models that rely on different statistical assumptions. We extend the standard switching regression model to allow non‐normality in the joint distribution of the error terms. After correcting for the sector selection bias and controlling for workers’ characteristics we find a private sector wage advantage. The wage premium is largest for workers with low education levels and declining for workers with higher educational levels. Given the regulatory and tax policies that pushed the private sector into the informal sphere of the economy during the period covered by our data, we argue that the state/private wage gap is likely to grow in the future. This will make it increasingly difficult for the state sector to attract and retain highly skilled employees.     

Unions and wage inequality: The roles of gender,skill and public sector employment

We examine the changing relationship between unionization and wage inequality in Canada and the United States. Our study is motivated by profound recent changes in the composition of the unionized workforce. Historically, union jobs were concentrated among low-skilled men in private sector industries. With the steady decline in private sector unionization and rising influence in the public sector, half of unionized workers are now in the public sector. Accompanying these changes was a remarkable rise in the share of women among unionized workers. Currently, approximately half of unionized employees in North America are women. While early studies of unions and inequality focused on males, recent studies find that unions reduce wage inequality among men but not among women. In both countries, we find striking differences between the private and public sectors in the effects of unionization on wage inequality. At present, unions reduce economy-wide wage inequality by less than 10%. However, union impacts on wage inequality are much larger in the public sector. Once we disaggregate by sector, the effects of unions on male and female wage inequality no longer differ. The key differences in union impacts are between the public and private sectors—not between males and females.     

From central planning towards a market economy: The role of ownership and competition in Vietnamese firms’ productivity

This paper examines the role of ownership and market competition in Vietnamese firms’ total factor productivity (TFP) from 2001 to 2011. Making use of a large panel dataset of manufacturing firms, we find that, on average, both foreign-owned enterprises (FOEs) and state-owned enterprises (SOEs) have performed better than privately owned enterprises (POEs) in terms of their TFP levels. However, while FOEs’ TFP ranked the highest in the period 2001–2006, SOEs “closed the gap” in the period 2007–2011. Moreover, we find that market competition has been effective in enhancing average firm productivity and in reducing the gaps in efficiency across ownership types. SOEs’ remarkable performance may be linked to several concurrent factors experienced during the period 2001–2011, namely, the process of restructuring the state sector during the 2000s, the increased economic integration due to the country's accession to the World Trade Organization (2007) and, finally, the preferential access to financial capital and land granted to SOEs. While some evidence supports SOEs’ equitization as an explanation for their remarkable productivity performance, WTO accession and cheaper access to inputs do not fully explain it.     

How Women Are Faring in the Australian Labour Market

The Economic and Social Outlook Conference that was held in 2011 carried a separate session on the role of women in the Australian labour market for the first time. Women now make up some 45 per cent of the workforce—in the late 1970s, the proportion stood at one‐third. While women play an increasingly more important role in the labour market, the gap between male and female earnings has shown stubborn persistence, at around 15 per cent. Various explanations include productivity‐related characteristics and the changing age profile of the female workforce. For low‐paid workers, these explanations are convincing; for high‐paid workers, both in the public and private sector, the pay gap remains unexplained.     

Wage Differentials between the State and Private Sectors in Moscow

In this study the 1997 Russian Labor Force Survey is used to investigate wage differentials between the state and the private sector in the city of Moscow. Our analysis demonstrates that substantial differences exist between private and state sector wages. We estimate the gap between private and state sector wages to be 14.3 percent for men and 18.3 percent for women. We also find gender differences in wages. Men in the private sector earn on average 23.7 percent more than women. The gender wage gap in the state sector is even higher at 32.5 percent. In the state sector, wages for both men and women increase as years of tenure increase. But in the private sector this is only true for men; women earn no return to tenure. The probability of employment in the private sector decreases with age and tenure.     

"Holding hands at midnight": The paradox of caring labor

Abstract

The gender wage gap in the United States narrowed considerably throughout the 1980s and then more slowly in the 1990s. Using a decomposition methodology and US Current Population Survey data, this study investigates the impact of deindustrialization's continuing shift in employment away from manufacturing to services on the US gender wage gap between 1990 and 2001. The study finds that the widening of the gender wage gap in the service sector caused a slowdown in the narrowing of the US gender wage gap. Within the service sector, two occupational elements affected the growing gender wage gap: women's entry into traditionally male occupations characterized by high wages and high gender wage differentials that resulted in the relative increase in men's wages compared to women's wages in these occupations.     

Firm ownership and internal labour practices in a transition economy

One feature common to many post‐socialist transition economies is a relatively compressed wage structure in the state‐owned sector. We conjecture that this compressed wage structure creates weak incentives for work effort and worker skill acquisition and thus presents adverse consequences for the entire transition economy if a substantial portion of the labour force works in the state sector. We explore firm wage incentives and worker training, as well as other labour practices and outcomes, in a transition setting with matched firm and worker data collected in one of the largest provinces of Vietnam – Ho Chi Minh City. The Vietnamese state sector exhibits a compressed wage distribution in relation to privately owned firms with foreign ownership. State wage practices stress tenure over worker productivity and their wage policies result in flatter wage–experience profiles and lower returns to education. The state work force is in greater need of formal training, a need that is in part met through direct government financing. In spite of the opportunities for government financed training and at least partly due to inefficient worker incentives, state firms, by certain measures, exhibit lower levels of labour productivity. The private sector comparison group to state firms for all of these findings is foreign owned firms. The internal labour practices of foreign firms are more consistent with a view of profit‐maximizing firms operating with no political constraints. This is not the case for Vietnamese de novo private firms that exhibit much more idiosyncratic behaviour and whose labour practices are often indistinguishable from state firms. The exact reasons for this remain a topic of on‐going research yet we conjecture that various private sector constraints, including limited access to formal capital, play an important role.     

公、私制企业效率工资的比较研究

造成国有、私营企业绩效差异的一个很重要原因是二者生产效率的巨大差异。造成国有、私营企业生产效率巨大差异的主要原因是国有企业不能解雇工人的劳动用工制度。国有企业的目标多元化要求其必须对稳定社会就业承担责任,即不能解雇工人,但这给国有企业对工人的管理激励带来很大困难,造成生产效率低下的严重后果。     

Comparable worth in a decentralized labour market: the case of Ontario

Abstract.  We document the application of pro‐active pay equity legislation to the private sector of the Canadian province of Ontario in the early 1990s. We report substantial lapses in compliance among smaller firms where the majority of men and women work. We also find that the pay equity law had no effect on aggregate wages in female jobs or on the gender wage gap. This experience provides unique perspectives on (1) the tensions between the workings of a decentralized labour market and the principles of comparable worth and (2) the obstacles to its extension to the private sector.

New evidence on public sector wage differentials

This paper examines the nature of wage differentials for men and women in the public sector, using a sample selection approach. This includes the self-selection that occurs in the sectoral choice process as well as the selection that arises in context of the labour force participation decision of men and women. Using 1991 Current population Survey data, it is found that male workers in the public sector on an average earn higher wages than male private sector workers, whereas the wage premium earned by women is undermined by a slightly greater degree of discrimination in the public sector     

Glass Ceiling or Sticky Floor? Exploring the Australian Gender Pay Gap

Using the Household, Income and Labour Dynamics in Australia survey, this paper analyses the gender wage gaps across the wage distribution in both the public and private sectors in Australia. Quantile regression techniques are used to control for various characteristics at different points of the wage distributions. Counterfactual decomposition analysis, adjusted for the quantile regression framework, is used to examine if the gap is attributed to gender differences in characteristics, or to the differing returns between genders. The main finding is that a strong glass ceiling effect is detected only in the private sector. A second finding is that the acceleration in the gender gap across the distribution does not vanish even after account is taken of an extensive set of statistical controls. This suggests that the observed wage gap is a result of differences in returns to genders. By focusing only on the mean gender wage gap, substantial variations of the gap will be hidden.     

Unionization,international integration,and selection

Abstract We study how unionization affects competitive selection between heterogeneous firms when wage negotiations can occur at the firm or at the profit‐centre level. With productivity specific wages, an increase in union power has: (i) a selection‐softening; (ii) a counter‐competitive; (iii) a wage‐inequality; and (iv) a variety effect. In a two‐country asymmetric setting, stronger unions soften competition for domestic firms and toughen it for exporters. With profit‐centre bargaining, we show how trade liberalization can affect wage inequality among identical workers both across firms (via its effects on competitive selection) and within firms (via wage discrimination across destination markets).
