Using propensity matching estimators to evaluate the impact of privatization on wages

Whether the transfer of ownership rights to the private sector leads to a decline or increase in wage growth is theoretically ambiguous, given that the outcome depends on the uncertain interaction between firms and workers. Using propensity matching techniques, this article investigates the effects of privatization on wages in the Portuguese banking industry. The empirical results, obtained from Quadros de Pessoal for the period between 1989 and 1997, generally show a negative (positive) short-run (long-run) effect of privatization on relative wage growth for both men and women retained in the privatized firms. Moreover, the results show that the most educated and experienced (oldest) workers, as well as those in the high skill occupational categories, were more likely to experience a negative wage effect.     

Male–female wage discrimination in Chinese industryInvestigation using firm‐level data1

We use firm‐level data to analyze male–female wage discrimination in China's industry. We find that there is a significant negative association between wages and the share of female workers in a firm's labour force. However, we also find that the marginal productivity of female workers is significantly lower than that of male workers. Comparing wage gaps and productivity gaps between men and women, we notice an intriguing contrast between state‐owned enterprises (SOEs) and private firms. The wage gap is smaller than the productivity gap in SOEs, while the converse is true for private firms. These results suggest that women in the state sector receive wage premiums, whereas women in the private sector face wage discrimination.     

企业改制模式和改制绩效——基于企业数据调查的经验分析

本文以上世纪90年代后半期的企业调查数据为基础,通过建立经济计量模型来研究公有企业的改制绩效,通过相应的技术处理消除企业的各种先天因素或改制前固有的优势,试图测试改制是否能够确实激发出显著的效率效应。分析发现,向私有产权方向改制的企业效率得到显著提高;不同的改制模式是改制绩效的重要决定因素,经营者持大股从效率上来讲是最优的改制方式,而平均分配的股份合作制的改制方式则具有较差的业绩效果。我们还讨论了其原因,以及为什么中国现阶段特定制度环境下最优的公司治理结构是大股东控股。我们认为给定当前制度背景下,最佳的改革方案之一是股权向经营者集中,股权合理定价。因为只有市场的初次分配是有效率的,才能得到收入再分配的源泉。在此基础上,国家可通过各种税收设计,进行较为公平合理的收入再分配。     

MARKET POWER AND EFFICIENCY IN A SEARCH MODEL*

We build a theoretical model to study the welfare effects and policy implications of firms’ market power in a frictional labor market. The main characteristics of our environment are that wages play a role in allocating labor across firms and the number of agents is finite. The decentralized equilibrium is inefficient and the firms’ market power results in the misallocation of workers from the high to the low productivity firms. A minimum wage exacerbates the inefficiencies by forcing the low‐productivity firms to increase their wage. Moderate unemployment benefits can increase welfare by improving the workers’ outside option.     

Privatization: Choosing the Optimal Time Path

We consider a government that wishes to choose the optimal time path of privatization. The government is concerned with maximizing output over some specified period while taking into account (1) the level of unemployment that will be attained as the end of that period, (2) the improvement in labor productivity of workers in the nationalized enterprises as a consequence of growing competition from privatized firms, and (3) the reemployment rate of the redundant workers displaced as their firms become privatized. We present a model exhibiting these features and derive the optimal policy that characterizes the rate of privatization within the period. When all of the elements noted above are present, we show it is never optimal to privatize instantaneously. We also show the relationship of the optimal rate of transition to the underlying objectives of the government. J. Comp. Econom., December 1993, 17(4), pp. 715-736.

中国国有企业民营化绩效研究

本文研究中国国有企业民营化是否有效的问题。我们通过对国企民营化进程的考察来对此问题作出经验解答。根据世界银行一份对中国五个城市、覆盖六个行业的近300家国有企业(SOEs)1996—2001年间的调查数据,我们发现:(1)绩效较好的国有企业优先被民营化;(2)总体上来说,中国的民营化是富有成效的,尤其是提高了销售收入,降低了企业的成本,并最终导致企业盈利能力和生产率的大幅提高;而且在获得这些收益的同时并没有带来大规模的失业问题;(3)由民营机构控股、彻底民营化的企业比那些仍然是国有控股、部分民营化的企业绩效表现更好。     

Wages in Managed Markets: An Explanation of the Gender Wage Gap?

Over the last decade or so in Australia, relative wages have declined in some female‐dominated occupations, notably in the care industries. This article argues that the strong growth in labour force participation of mature‐aged women has allowed wages to remain low in these ‘managed’ industries. Limited mobility across industries and occupations, at least in part due to preferences for part‐time work, and an institutional wage‐setting mechanism also play a role. Growing demand for workers in the care industries, rising skill levels of women, and slowing growth in participation as rates converge with those of men will contribute to stronger wage growth in the future.     

THE IMPACT OF THE MINIMUM WAGE ON FEMALE EMPLOYMENT IN JAPAN

This article examines the impact of the minimum wage on employment, focusing on women in their 20s and 30s, who are known to be typical low‐wage workers in Japan. The results, based on a panel estimation, suggest that the minimum wage has a measurable impact on employment; the workers whose current wage is below the revised minimum wage are about 20–30 percentage points less likely to be employed in the following year than comparable low‐wage workers who are not affected by the revision of the minimum wage. The estimation results are sensitive to the choice of the control group. (JEL J23, J38, J88)     

ECONOMIC TRANSITION AND THE GENDER EARNINGS GAP IN CHINESE INDUSTRY: THE ROLE OF FIRM CHARACTERISTICS

This paper analyzes the gender wage gap in the post‐reform Chinese industry using a unique employer‐employee matched dataset. The analysis shows that the sex‐related wage premiums at the firm level account for almost all the portion of the gender wage gap that is not explained by observed personal characteristics. It is found that firms which have a larger pay gap between men and women are more likely to operate in the market with fierce competition, subject to a hard budget constraint, adopt piece rates, and have a lower degree of employees' influence.

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.     

Spillovers of Equal Treatment in Wage Offers

We analyse a labour‐matching model with wage posting, where – reflecting institutional constraints – firms cannot differentiate their wage offers within certain subsets of workers. Inter alia, we find that the presence of impersonal wage offers leads to wage compression, which propagates to the wages for high productivity workers who receive personalized offers.     

Investment abroad and labour adjustment at home: evidence from UK multinational firms

Abstract. This paper provides new evidence on the effects of overseas FDI on the skill‐mix of multinational firms’ home‐country operations. The analysis exploits China's WTO accession to identify the impact of outward investment into a low‐wage economy and uses plant‐level data to investigate changes in industrial structure within firms driven by plant closures. As predicted by models of vertical FDI, the paper demonstrates that overseas investment in low‐wage economies is associated with asymmetric effects on workers in low‐ and high‐skill industries in the home economy and, in particular, with firms closing down plants in low‐skill industries.

THE SCOPE FOR NON‐PROFIT OBJECTIVES IN A MIXED OLIGOPOLY UNDER INTERNATIONAL COMPETITION

We ask how the scope for non‐profit objectives in a state‐owned enterprise (SOE) in a mixed oligopoly changes because of competition from firms in another country. There is no change if costs and demand are given, unless the trade partner is a low‐cost country. However, the scope for non‐profit objectives is limited by the country's relative size if wages are market‐clearing and if workers and firms are stationary, because of reduced competitiveness caused by higher real wage rates. The total surplus is then not affected by the actions of the SOE. International trade does not otherwise reduce the scope for its non‐profit objectives if workers and firms are mobile, but productivity differences might require restrictions in order to avoid a complete relocation of the workforce in either country.     

Training,productivity and wages: An investigation of China's manufacturing enterprises in a privatization era

We estimated a structural model of production and wage determination in which labour quality can be affected by a firm's training decision using data of China's manufacturing enterprises in an era of privatization (2004–2007). Training increased both productivity and wages, but the former increased more, which explained the voluntary provision of on-the-job training. Our results also indicate that state-controlled enterprises' investment in training could be both privately and socially efficient; unions played a role in promoting training; it might be more privately and socially efficient for manufacturing firms to prioritize training resources to lower-educated, female and junior workers, if they had not done so, during privatization.     

MINIMUM WAGES AND GROSS DOMESTIC PRODUCT

This study is the first to explore the relationship between minimum wage increases and state gross domestic product (GDP). Using data drawn from the Bureau of Economic Analysis (BEA) and the Current Population Survey (CPS) from 1979 to 2012, I find no evidence that minimum wage increases were associated with changes in overall state GDP. However, this null finding masks substantial heterogeneity in the productivity effects of minimum wages across industries and over the business cycle. Difference‐in‐difference‐in‐difference estimates suggest that a 10% increase in the minimum wage is associated with a short‐run 1% to 2% decline in state GDP generated by lower‐skilled industries relative to more highly skilled industries. This differential appears larger during troughs as compared to that during peaks of the state business cycle. (JEL J3, J4, L5)     

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).     

WAGES AND EMPLOYMENT IN THE U.S. APPAREL INDUSTRY

This article uses individual-level data from the U.S. Census, Public Use Microdata Sample (PUMS), to examine wages and employment in the U.S. apparel industry. Total employment in this sector has been falling since 1970, and its overall average wage is the lowest of 25 industry aggregates. But disaggregation by gender, education, and nativity reveals that groups of highly educated male native workers earn higher average wages in apparel than in other industries. Moreover, after adjusting for observed individual differences in human capital (in addition to the three characteristics used to form worker subsets), highly educated male natives earn positive wage premiums in this sector. In contrast, most categories of immigrants and female natives earn relatively low average wages and experience negative wage premiums in apparel. This variation in the adjusted industry wage premiums across worker groups may be related to apparel's relative exposure to imports and immigrant workers.     

When does transition increase the gender wage gap?

In the context of underlying stability in female participation rates, the gender wagegap, measured by the log of monthly wages, more than doubled in Belarus from 1996 to 2006. In this respect, the country has experienced a variant of the transition which occurred in the former Soviet Union where relative female wages fell by more than female participation. We have used the Machado and Mata (2005) analysis of the gender gap distribution. This reveals that the effect of coefficients on observed characteristics in widening the gap was increasing over time, especially in the lower and middle deciles of the wage distribution. At the same time, the effect of the characteristics themselves in reducing the gap was shrinking. The decomposition of changes in the gap over time, based on Juhn et al. (1991) , confirms that the contraction of women’s relative wages has been caused both by a deterioration in the observed characteristics of female workers and by the associated remuneration. Changes in the residual wage distribution tend to slightly reduce the gap rather than, as is the case elsewhere, to increase it. The analysis carried out in line with Neuman and Oaxaca (2004) suggests that the increased gap was not caused by sample selection. Instead, two observed factors are found to be mainly responsible for the results: hours of work have increased for men more than for women and women have experienced segregation in low‐wage industries.     

Unobserved Individual and Firm Heterogeneity in Wage and Job‐Duration Functions: Evidence from German Linked Employer–Employee Data

Abstract. We analyse the correlations between individual and firm fixed effects, and wage and job‐duration functions. Our results for large firms suggest that low‐wage firms tend to be stable firms, suggesting that lower wages can buy job stability. Furthermore, high‐wage workers sort into the stable low‐wage firms. Our interpretation is that high‐wage workers have a higher wage to insure against job loss and can afford more easily to forgo wages in favour of job stability. This may provide an explanation of the puzzle identified in previous literature that high‐wage workers are matched to low‐wage firms.
