Wage Determination in Rural Russia: A Stochastic Frontier Model

This article examines wages in rural Russia after the first decade of economic transition using data from a nationally representative household survey. The stochastic frontier analysis reveals that Russia's rural labour markets place high value on human capital. The overall level of rural wages, however, is very low, with the median wage 10% below the official subsistence level. The gender pay gap severely depresses women's wages. A woman with the same skills as a man is paid only 47% of the man's wage. Rural workers who receive income from their personal plots accept significantly lower wages. Private firms pay considerably higher wages than state or collectively owned firms, but account only for one fifth of rural workers.     

Adverse selection in health insurance markets? Evidence from state small-group health insurance reforms

The past decade witnessed major changes in state laws governing the sale of health insurance to small employers. States took measures to restrict insurers' ability to distinguish between high and low-risk customers because of concern about the low rate of coverage among workers in small firms, the high prices in the small-group market and the absence of federal health reform. Using both individual-level and employer-level data, I test predictions about the effect of reforms on the employer-provided health insurance market. I estimate these effects for small firms and their workers using large firms and their workers in the same states, as well as large and small firms and their workers in non-reform states, as comparison groups. I find the reforms decreased the rate of employer coverage on average for workers in small firms by less than two percentage points. Within small firms, low-expenditure individuals experienced a larger decline in the rate of coverage through their employer, while the coverage rate of high-expenditure individuals rose slightly in some specifications. There is also evidence that comprehensive reforms increased premiums slightly for small employers, and that most of this increase was passed on to workers through higher employee contributions.     

The Role of Expectation on Job Search and the Firm Size Effect on Wages

We formulate dynamic games which give a rationale to the firm size–wage effect that the sheer firm size increases wages. We postulate that past wages of large firms are known to new employees, while those of small firms are not. Large firms can credibly induce workers to expect high future wages and reduce turnover, while small firms have no choice but to be myopic and pay low wages. The equilibrium wage differential obtains under the same worker characteristics and production function. We provide empirical evidence that workers' expectations depend on firm size and affect wages as predicted by our model.     

The evolution of wage inequality in Italy

This article analyses the evolution of inequality in yearly and daily wages between and within groups of blue and white collar, using the INPS-ISFOL database for the period 1985 to 1999 in Italy. Between-group inequality increased in the 1990s as clerical wages grew slowly, whereas blue collars' wages remained nearly constant. Within-group inequality increased only if measured by daily wages. The covariance structure analysis shows that inequality comes from persistent differentials among older workers and from high income volatility for younger cohorts. Within inequalities in office and manual workers are driven by the growth of permanency for the older cohorts (individual abilities, say experience, matter more) and by the growth of income volatility for the younger cohorts (luck in the labour market). Within each group, low paid workers during their career acquire earning gains for their abilities and reduce differentials with respect to high paid workers.     

Equilibrium Wage Dispersion,Firm Size,and Growth

This paper analyzes a model of equilibrium wage dynamics and wage dispersion across firms. It considers a labor market where firms set wages and workers use on-the-job search to look for better paid work. It analyzes a perfect equilibrium where each firm can change its wage paid at any time, and workers use optimal quit strategies. Firms trade off higher wages against a lower quit rate, and large firms (those with more employees) always pay higher wages than small firms. Non-steady-state dispersed price equilibria are also analyzed, which describe how wages vary as each firm and the industry as a whole grow over time.

What did China’s labor contract law do to its private manufacturing firms?

Well-intended employment protection legislation may have adverse consequences. This paper uses Chinese firm-level data to assess the impacts of China’s Labor Contract Law, effective on January 1, 2008. My results show that, relative to public firms, private firms as a whole were negatively affected in terms of firm-level year-to-year employment changes. The law had negligible effects on employment and wages in firms with high wages. At the same time, employment fell and wages rose in firms with low wages. Moreover, firms who did not train workers intensively to acquire firm-specific skills had more job turnover than firms who did. Finally, I study how labor demand responded to the law along the extensive margin. For regions that experienced abrupt declines in labor mobility, possibly due to stricter labor regulation enforcement following the enactment of the Labor Contract Law, firm exit rose significantly, suggesting large incidence of mass layoff.     

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.     

Firm size,employment risk and wages: further insights on a persistent puzzle

Recent inquiries into the observed positive relationship between wages and firm size suggest that unobservable characteristics give rise to a sorting of workers into large and small firms. Specifically, smaller firms tend to offer more unstable employment prospects and will tend to attract workers who are themselves unstable. As demonstrated by empirical analysis, the risk of permanent employment separation (i.e. the risk of firm failure) is in fact negatively correlated with firm size. Moreover, when this measure of employment risk is included as a determinant of wages, the independent influence of firm size on wages vanishes. These results suggest that firm size merely proxies for the risk of firm failure by capturing unobservable sources of heterogeneity in workers and firms.     

LOCAL LABOR MARKETS,JOB MATCHING,AND URBAN LOCATION*

We present a new way of modeling local labor markets by linking the space of workers' skills and the physical space of cities. The key lesson of our analysis is that firms exploit workers in these two spaces by setting wages that are below the competitive level. The degree of monopsony power depends on the elasticity of the firm's labor pool, which is inversely related to the costs workers incur in commuting and acquiring skills. Our analysis thus shows how socioeconomic ghettos emerge as workers with poor skill matches are also those who incur the highest commuting costs.     

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.     

效率工资理论的新发展：阿克洛夫的观点

阿克洛夫的效率工资理论,通过吸收社会学、人类学的研究成果,将人的劳动行为看成基于公平出发的社会习俗。根据这一习俗,企业支付的工资不少于工人预期的公平工资,而工人根据企业支付的工资决定自己的努力程度,从而决定自己的边际产出。对于追求利润最大化的企业来说,并非支付的工资越高越好,支付工人的工资应等于工人的边际产出。当公平工资高于市场出清工资时,非自愿失业问题出现,工人技术程度与其失业率负相关。二元劳动力市场的现实与人类内生的行为规范,使得非自愿失业问题的解决前景十分悲观。     

The Labour Market Impact of Adult Education and Training: A Cohort Analysis

Education boosts individuals' productivity and wages. Yet many individuals leave school with minimal skills and qualifications. One way for these workers to catch up might be lifelong learning. We find that a particular form of lifelong learning, work related training, does have a positive impact on earnings. However, firms tend only to train those workers who will gain from training. Training does benefit those chosen to receive it but if all workers received training, the average impact on wages would be low. Hence, this form of lifelong learning is not necessarily an effective way of raising wages.     

Skills scarcity and export intensity

We describe a model of trade with skills-based product differentiation and non-proportional trade costs that predicts a positive correlation between firms' export intensity, the price of their exports and the wages they pay to their workers. In equilibrium, firms that employ workers with comparatively scarcer skills export a larger proportion of their output, pay higher wages and charge higher prices. In line with empirical evidence, the model predicts that trade liberalization can cause the distribution of earnings to become more polarized, with patterns that reflect the heterogeneous effects of trade liberalization on firms' export performance.     

Do Employees’ Sickness Absences React to a Change in Costs for Firms? Evidence from a Natural Experiment*

We analyse the impact of a social security reform that changed the costs incurred by firms due to sickness absences. The reform abolished a compulsory insurance for firms, which insured them against the wages paid to sick blue-collar workers. During the first year after its introduction, we estimate that the reform resulted in about 6.3 percent fewer sickness absences, and in about 8.6 percent fewer absence days. We do not find evidence for changes in hiring or firing, and we find only limited workforce composition changes. We do not find spillover effects on the absences of white-collar workers. Robustness checks confirm these results.     

Effects of female labour force attachment on health in Australia

This study examines the impact of female labour force attachment on health in Australia, where health care is socially provided. Longitudinal panel data from Women’s Health Australia is used in a metric analysis to capture the impact of labour market attachment on the physical component health score of relatively young and older female workers. After controlling for the healthy worker effect – wherein firms hire and retain the healthiest workers – and other health‐related changes in socio‐economic status, the analysis suggests that even a moderate attachment to the paid labour force has benevolent effects on health relative to no or marginal attachment. Given the existing social structure in Australia, remunerative work generally appears to enhance the health of young women and arrest the decline of health for older female workers.     

Worker flows, job flows and firm wage policies

Like many transition economies, Slovenia is undergoing profound changes in the workings of the labour market with potentially greater flexibility in terms of both wage and employment adjustment. To investigate the impact of these changes, we use unique longitudinal matched employer‐employee data that permits measurement of employment transitions and wages for workers and enables links of the workers to the firms in which they are employed. We can thus measure worker flows and job flows in a comprehensive and integrated manner. We find a high pace of job flows in Slovenia especially for young, small, private and foreign‐owned firms and for young, less educated workers. While job flows have approached the rates observed in developed market economies, the excess of worker flows above job flows is lower than that observed in market economies. A key factor in the patterns of the worker and job flows is the determination of wages in Slovenia. A base wage schedule provides strict guidelines for minimum wages for different skill categories. However, firms are permitted to offer higher wages to an individual based upon the success of the worker and/or the firm. Our analysis shows that firms deviate from the base wage schedule significantly and that the idiosyncratic wage policies of firms are closely related to the observed pattern of worker and job flows at the firm. Firms with more flexible wages (measured as less compression of wages within the firm) have less employment instability and are also able to improve the match quality of their workers.

On modeling task,skill and technology upgrading effects of globalization with heterogeneous labor

We adapt Yeaple's (2005) heterogeneous agent framework to model firms in the North as making explicit offshore outsourcing decisions to cheap-labor economies. We highlight how firms' technology transformations due to globalization will induce skill upgrading in the North, increase aggregate productivity, average wages and therefore total welfare at the cost of increased wage inequalities. We analytically derive conditions under which all consumers – including lower-skilled workers – might nevertheless gain from the surge of offshore outsourcing. We also show that extending the model to the more realistic case of multi-product firms tends to boost the potential welfare gains.     

Immigration-induced effects of changes in size and skill distribution of the labor force on wages in the U.S.

We isolate the effect of immigration-induced changes in the size and skill distribution of the labor force on labor market outcomes using a model in which firms endogenously respond to these changes. We analytically show that while the immigration-induced increase in the size increases the relative wages, employment and output shares of the skill intensive sector, changes in the skill distribution lead to analytically ambiguous effects. We derive quantitative results for the US economy under different counter-factual scenarios with respect to immigration-induced changes in size and skill distribution of the labor force, where these changes resemble those of U.S. as a whole, New York, California and Canada, and reflect different immigration policy regimes. For example, immigration increases the mass of workers at the lower range of the skill distribution in the U.S., and the upper range in Canada. Regardless of these differences across scenarios, our quantitative results indicate that immigration increases the relative average wages of the skill intensive sector. Further, real wages of all workers increase due to reduced prices caused by the increased size of the labor force.     

Micro Foundations for Wage Flexibility: Wage Insurance at the Firm Level*

To what extent do firms insulate their workers' wages from fluctuations in product markets? Which firm and worker attributes are associated with wage flexibility at the micro level? We first rely on Guiso, Pistaferri and Schivardi (2005) to estimate dynamic models of sales and wages, finding that in Portugal, workers' wages respond to permanent shocks on firm performance, as opposed to transitory shocks. We then explore the factors associated with wage flexibility, finding that collective bargaining and minimum wages are associated with higher wage insurance by the firm, while the threat of firm bankruptcy reduces it. Managers receive less protection against permanent shocks than other workers.
