Liberalization and the Changing Inter‐industry Wage Structure of the Organized Manufacturing Sector in India, 1973/74–2003/04

This paper examines the inter‐industry wage structure of the organized manufacturing sector in India for the period 1973/74–2003/04 by estimating the growth of average real wages for production workers by industry. Using wage data on 51 three‐digit industries, our estimation procedure obtains estimates of growth of real wages per worker that are wholly deterministic in nature by accounting for any potential structural break(s) associated with the reforms. Our paper identifies three distinct regimes—pre‐reform, first phase reforms and second phase reforms, over which real wages have grown at varying rates for each industry. Our findings suggest that the inter‐industry wage differences have become more pronounced in the post‐reform periods. The paper provides new evidence from India on the need to consider seriously the hypothesis that industry affiliation is potentially an important determinant of wages when studying any relationship between reforms and wages.     

The establishment-size wage premium: evidence from European countries

This study examines the magnitude and determinants of the establishment-size wage premium in five European countries using a unique harmonised matched employer–employee data set (the 1995 European Structure of Earnings Survey). This data set enables to test the validity of various traditional explanations of the size wage gap (i.e. the labour quality hypothesis, the theory of compensating wage differentials, the role of monitoring and institutions) and of more recent hypotheses (i.e. size differences in job stability and in the concentration of skilled workers). We find some support for traditional explanations, but there remains a significant wage premium for workers employed in large establishments. Further results indicate that the magnitude of this premium fluctuates substantially across countries and appears to be negatively correlated with the degree of corporatism.     

Wage inequality between and within groups: trade-induced or skill-bias technical change? Alternative age models for the UK

According to recent econometric studies, technical progress is the main source of the increasing skill premium in the UK and the US. However, it is not yet clear if technical progress is skill-bias or sector-bias and, most importantly, if the use of foreign technology has a role to play. By using alternative AGE models for the UK economy, I show that both trade-induced sector-bias technical change and skill-bias technical change can explain the stylised facts of the UK economy: tertiarisation; deindustrialisation; openness to foreign markets; increased skill premium; rise in wage inequality within the skilled; and unskilled labour groups. However, the model with sector-bias technical change due to trade performs better, because it can also explain two other important stylised facts: the decline of the wage rate of unskilled workers; and the large increase of imported capital goods.     

Are low-skill public sector workers really overpaid? A quasi-differenced panel data analysis

Public–private sectoral wage differentials have been studied extensively using quantile regression techniques. These typically find large public sector premiums at the bottom of the wage distribution. This may imply that low skill workers are ‘overpaid’, prompting concerns over efficiency. We note several other potential explanations for this result and explicitly test whether the premium varies with skill, using Australian data. We use a quasi-differenced Generalized Method of Moments (GMM) panel data model which has not been previously applied to this topic, internationally. Unlike other available methods, this technique identifies sectoral differences in returns to unobserved skill. It also facilitates a decomposition of the wage gap into components explained by differences in returns to all (observed and unobserved) skills and by differences in their stock. We find no evidence to suggest that the premium varies with skill. One interpretation is that the compressed wage profile of the public sector induces the best workers (on unobserved skills) to join the public sector in low wage occupations, vice versa in high wage occupations. We also estimate the average public sector premium to be 6% for women and statistically insignificant (4%) for men.     

The Value of Transferable Skills

Most studies on skill transferability focus on the return to capabilities developed in the initial job and disregard the different characteristics of the origin and the destination industries. In contrast, this article assesses the borders of skill transferability by comparing the return to skills for firm stayers, firm changers in the same industry, and firm changers to other industries. Based on a sample of Portuguese employees in retail banking, our results confirm significant inter‐firm and inter‐industry skill transferability. Difference‐in‐differences estimates with propensity score matching show that firm switchers benefit from a wage premium compared to firm stayers. However, the wage premium drops sharply when movers leave the banking sector.     

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.     

The minimum wage, employment, and the AS-IF methodology: A forecasting approach to evaluating the minimum wage

Out-of-sample employment forecasts for 33 U.S. industries which are likely to be sensitive to the federal minimum wage are, more often than not, more accurate when information about the minimum wage is not taken into account. This is true even in instances where this information improves wage forecasts. When employment forecasts conditional on the minimum wage are better, the improvement is typically small. These results are invariant to the number of workers previously making less than the new minimum wage, and to the value of the minimum wage relative to industry average wages.

Long-run costs of piecemeal reform: Wage inequality and returns to education in Vietnam

In this paper, we examine changes in wage structure and wage premia during Vietnam’s transition from command to market economy. Relative to other work in this literature, our paper is unique in that we identify the policies that lead to such changes. By examining skill premium trends along the two dimensions of particular importance to the transition—state or non-state firms, and traded or non-traded industries—we are able to separate the contribution of external liberalization to wage growth and rising skill premia from that of domestic labor market reforms, and to examine potential interactions between the two types of reform. The results point to the high cost of incomplete reform in Vietnam. Capital market segmentation creates a two-track market for skills, in which state sector workers earn high salaries while non-state workers face lower demand and lower compensation. Growth is reduced directly by diminished allocative efficiency and reduced incentives to acquire education, and indirectly by higher wage inequality and rents for workers with access to state jobs.     

WILL TAX‐BASED HEALTH INSURANCE REFORMS HELP THE SELF‐EMPLOYED STAY IN BUSINESS?

The self‐employed face a tax‐induced disadvantage relative to wage and salary workers when it comes to the payment of health insurance premiums. This paper uses a panel of individual tax return data to test whether lower health insurance premium costs because of an expanded tax incentive result in longer periods of self‐employment. The results suggest that households claiming the deduction are indeed less likely to exit self‐employment. Equalizing the treatment of health insurance premiums for the self‐employed and wage workers by allowing full deductibility from Self‐Employment Contributions Act (SECA) taxes would result in a 7% decrease in the probability of exit.

技能偏向型技术进步必然加剧工资不平等吗?

劳动经济学界在20世纪90年代形成了共识:美国等OECD国家从70年代末到90年代末的教育升水(不同教育水平工人的工资差距)持续上升是由技能偏向型技术进步导致的。但90年代共识无法解释第二次世界大战后美国在技能偏向型技术进步下教育升水并非总是上升的事实。此外其理论基础在于技能偏向型技术进步下抑制低技能劳动力需求的腐蚀效应和提升高技能劳动力需求的市场规模效应会加剧工资不平等。本文指出其理论基础的缺陷,并将教育效率和劳动力市场的技能供求关系整合在一个技能偏向型技术进步与工资不平等都处于内生演化的动态模型中。本文证明技术进步率的提升在短期会提升工资不平等,但当教育系统的效率处于一定的区间时,技能偏向型技术进步在长期会降低工资不平等。因此,本文的研究挑战了90年代共识的悲观论点,并丰富了有关技能偏好型技术进步对于工资不平等影响的研究。     

Wage Growth Distribution and Changes over Time: 2001–2018

We explore how much wage growth varies among Australian employees and how it has changed over the 2001–2018 period. The results show that, after increasing between 2002 and 2007, wage growth significantly slowed post 2008, and particularly from 2013 onwards, returning to early 2000s levels. Employee age, education, employment contract, occupation and industry explain a large share of differences in wage growth between individuals. Employee occupation is more important post‐2008 than pre‐2008, whereas education is more important pre‐2008. Finally, casual employees receive a wage growth premium during periods of economic upturn and a penalty during downturn.     

Inter-industry wage premiums and industry-specific productivity in Taiwan

By using Taiwan's Manpower Utilization Survey data for the 1978–2000 period, different inter-industry wage premiums in Taiwan are observed and the impact of workers’ industry-specific productivity on the wage explored. The empirical results show that industry-specific skills result in industry stayers having higher wages than industry switchers through their reservation wages. It is also found that the pre-displacement industry affiliations that are associated with the post-displacement wages are explained by the workers’ unobserved abilities. Furthermore, by comparing the different residual means between industry switchers and stayers based on each industry's wage equation, it is found that the switchers are low-wage workers who tend to be located in the high-wage industries. The high-wage industry leavers are also found to have higher post-displacement wage residuals than the low-wage industry leavers. These results suggest that the differences in industry wage premiums may be explained by the industry-specific productivity.     

High skills pay off: the changing wage structure during economic transition in Poland

Economic transition turns the inherited wage structure upside down. Changes are rapid and dramatic. The Polish example shows that even in the first year of market-oriented reforms, there was a marked increase in earnings inequality, a dramatic rise in the wage premium for white-collar skills, and a significant jump in the returns to education. In contrast, skills acquired under the old system lost their value. It is younger workers who are rewarded with higher wages. The changes are spearheaded by the private sector, where inequalities and the educational premium are higher than in the public sector. Privatization, thus, has its social aspects in that it strengthens the incentive for human capital investment. This paper documents these changes and sets out possible explanations.     

The Efficiency of China's Banking Industry and the Determinants

The recent global financial crisis highlights the importance of a sound financial sector for economic development. This paper evaluates the economic efficiency of China's banking industry and investigates the determinants of this efficiency. Our analysis shows that the average economic efficiency of joint-stock commercial banks is highest, followed by the ‘Big Four’ state-owned commercial banks and city commercial banks. The economic inefficiency of these banks during the past 15 years was mainly caused by technical inefficiency, and this technical inefficiency was mainly caused by scale inefficiency. Using the scores of efficiency as dependent variables, the paper also comprehensively studies the impact of (1) the characteristics of individual banks, (2) the characteristics of the whole banking industry and (3) macroeconomic factors on banking efficiency. The results suggest a number of factors that banks can work on to improve efficiency and lend support to deepening reforms in the Chinese banking industry, including regulatory reforms that require capital adequacy in a more strict way, reforms that introduce more competition and, more broadly, reforms that aim at establishing institutions that can truly commercialize Chinese banks. Last but not least, the efficiency of banking depends on healthy growth of the overall economy.     

Money and rank in the labor market

We analyze the gains/losses in wage and in rank position for workers switching firm. Voluntary movers enjoy a wage premium relative to stayers, but that premium declines with rank inside the new firm, indicating that movers are trading-off money and rank.     

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.     

City Size and Wage Disparity in Segmented Labour Market in China

The relation between city size and wage inequality is well established for Western countries. This paper finds that city size–wage premium exists across Chinese cities to a lower extent than the Western world. Further, using a simplified model on the Chinese Household Income Project survey data, we find that the city size–wage premium varies with difference in skills among urban citizens. The variation amounts to 50% more for the high‐skill workers compared with their low‐skill counterparts. Moreover, owing to the presence of segmented labour market, the patterns of city size–wage premium and city size–wage inequality premium are notably different for the migrants, who receive a much lesser wage than the citizens and do not experience wage variation owing to their skill heterogeneity.     

Lower coverage but stronger unions? Institutional changes and union wage premia in Central Europe

In this paper we use the national samples from the European Structure of Earnings Survey (ESES) to analyze the evolution of the wage premium of firm- and industry-level agreements in the Czech Republic, Hungary, and Poland (the CE3) around the time of their accession to the EU. We find that despite a generalized reduction in union coverage in these countries, the union wage premium after accession to the EU became bigger and statistically more significant for Poland and Hungary, particularly for industry-level agreements. We interpret these findings in terms of the institutional reforms that occurred in the CE3 between 2002 and 2006. These reforms, which were prompted by the EU Commission's requirements for EU accession, increased the social partners' ability to bargain and enforce wage agreements, and made industry-level unions more effective in guaranteeing the protections provided by labor standards. Results are less conclusive for the Czech Republic, probably due to factors that attenuate the effect of bargaining coverage upon wages, e.g. a smaller effect of institutional reforms, a greater use of mandatory extension mechanisms, the more radical firm restructuring during transition in that country.     

Concentration and Wage Earnings in an Open Economy: A Case Study of Korea

The object of this paper is to increase our understanding of the effect of output market power (the degree of concentration in an industry) on wage earnings in Korea. We conduct a series of econometric investigations based on the traditional human capital theory and find that workers in a more concentrated industry are paid higher. This wage premium is not explained in terms of the differences in the quality of labor and/or compensating factors. It suggests to us that the conventional estimates of the misallocation of resources due to the output market power are underestimated since this source of higher unit costs is disregarded.

Economic returns to schooling in urban China, 1988 to 2001

This study provides estimates of the returns to schooling in urban China over an extended period of economic reforms. We find a dramatic increase in the returns to education, from only 4.0 percent per year of schooling in 1988 to 10.2 percent in 2001. Most of the rise in the returns to education occurred after 1992 and reflected an increase in the wage premium for higher education. The rise is observed within groups defined by sex, work experience, region, and ownership, and is robust to the inclusion of different control variables. The timing and pattern of changing schooling returns suggest that they were influenced strongly by institutional reforms in the labor market that increased the demand for skilled labor.
