The Polish wage inequality explosion1

This paper presents and analyses the sharp increase in hourly wage inequality after 1998 in Poland. The increase was similar in magnitude to the much‐studied increase in British wage inequality during the 1980s. Using data from the Polish Labour Force Survey, we find this increase to be associated with rising wage differentials and within‐group variances at both the upper and lower ends of the wage distribution. These increases are associated with differences in wage‐setting patterns between the public and private sector as well as with the rapid increase in demand for educated labour. One important difference between the sectors is the lack of an impact of local labour market conditions, or wage curve, clearly evident in private sector wages, on public sector wages.     

A contribution to the public–private wage inequality debate

This paper studies the public–private wage inequality in Romania. Although public sector employment is perceived as safer and offering more benefits, we find that in Romania it also offers higher wages, after controlling for experience, education and gender. This result is at odds with the negative premium uncovered in other transition economies. The public–private wage premium is increasing across the wage distribution, leading to more inequality in the public sector. Decomposing the wage premium into the effect of personal characteristics, coefficients and residuals, we show that only about half of this premium can be attributed to personal characteristics, especially in the top half of the wage distribution. We also find that the number of other public sector employees in the family is a significant driver of public sector employment, facilitating access to jobs. However, the effects of self‐selection are negligible, the premium being still positive and significant after controlling for this.     

Employment and Wages in the Private and Local Government Sectors in a Centralized Fiscal System

This paper discusses the interaction between the local government and private sector in an institutional context consistent with a centralized fiscal system. Under decentralized wage setting in the private sector, the effects of shocks in the two sectors depend on whether private and local public goods are substitutes or complements in the union utility function. Higher wage markup in the local government sector unambiguously decreases government output while the effect on private sector employment is ambiguous. Higher income taxes have ambiguous effects on local government output. Shocks in the private sector can be reinforced through feedback effects from the local government sector. A shift from decentralized to centralized wage setting in the private sector reduces wages and increases employment in both sectors.     

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.     

Employment and Capital Accumulation in Unionised Labour Markets: Evidence from five south-European countries

This paper analyses the link between employment and capital accumulation in unionised labour markets by using a dynamic monopoly union model. The role of wage setting is also explored within the above context. The empirical analysis is based on annual data from the manufacturing sector of five European countries (France, Greece, Italy, Portugal and Spain). It verifies that capital accumulation has a positive influence on employment. Concerning wages, there is evidence that, in most countries, income opportunities in the public sector play an important role in wage determination. A larger public sector crowds out private investment and employment by serving as a safety net that allows wage setters to push for higher wage demands.     

Public–Private Sector Wage Differentials in Australia

This paper examines public–private sector wage differentials in Australia. After controlling for observed characteristics and individual fixed effects, we show that on average workers in the public sector earn about 5.1 per cent more in hourly wages than those in the private sector. The wage premium is slightly higher for females than males. Using a panel data quantile regression model with fixed effects, we show that the positive wage effects of public sector employment are heterogeneous, with comparatively larger impact at the lower end of the wage distribution than at other parts. We also find evidence of heterogeneity in the public sector wage premiums by qualification, time period, occupation and state/territory.     

Public Sector Employment,Wage Inequality and the Gender Pay Ratio in the UK

This paper assesses the relative contributions of the different systems of pay determination in the private sector and the public sector toward the changing level of wage inequality and the gender pay ratio in the UK. The greater centralisation of pay arrangements in the public sector compared with the private sector in the UK suggests that public sector employment may have acted to offset the widening wage inequality seen in recent years, as well as making an important contribution to the increase in women's relative average earnings compared to men. This issue is addressed by drawing on unpublished occupational hourly earnings data from the New Earnings Survey and applying decomposition of the Theil index of wage inequality to analyse both static and dynamic trends. The change in wage inequality for the period 1986 to 1995 primarily reflected the change in wage dispersion within the private sector, and the narrowing of the gender pay gap among the public sector workforce was an important factor in explaining the overall improvement in women's relative earnings. The paper argues that the relatively centralised pay arrangements in the public sector, compared with the private sector, played an important role in slowing the increase in wage inequality and narrowing the gender pay gap. As such, future policies to decentralise pay determination in the UK public sector may exacerbate the increasing level of wage inequality and reverse women's recent relative pay improvements.     

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.     

Labour market effects of public capital stock: evidence for the Spanish private sector

This paper provides a new rationale for the positive effect of public capital stock on employment and wages. We show that higher levels of public capital reduce wages along the wage equation and enhance employment due to the resulting larger elasticity of labour demand with respect to wages. The estimation of a structural model for the Spanish private sector reveals that this wage channel is empirically relevant. We use the estimated parameters to simulate the recent incidence of the ratio of public to private capital stock on the private sector economic performance. We find (i) sizeable effects on employment, capital stock and gross domestic product, and (ii) that the wage channel is particularly important for employment.     

Informality,public employment and employment protection in developing countries

This paper proposes an equilibrium matching model for developing countries’ labor markets where the interaction between public, formal private and informal private sectors are taken into account. Theoretical analysis shows that gains from reforms aiming at liberalizing formal labor markets can be annulled by shifts in the public sector employment and wage policies. Since the public sector accounts for a substantial share of employment in developing countries, this approach is crucial to understand the main labor market outcomes of such economies. Wages offered by the public sector increase the outside option value of the workers during the bargaining processes in the formal and informal sectors. It becomes more profitable for workers to search on-the-job, in order to move to these more attractive and more stable types of jobs. The public sector therefore acts as an additional tax for the formal private firms. Using data on workers’ flows from Egypt, we show empirically and theoretically that the liberalization of labor markets plays against informal employment by increasing the profitability, and hence job creations, of formal jobs. The latter effect is however dampened or even sometimes nullified by the increase of the offered wages in the public sector observed at the same time.     

Public or Private Sector Wage Leadership? An International Perspective*

Whether a government acts as a wage leader, placing pressure on private‐sector wages (more open to competition), or whether it plays a passive role and merely follows wage negotiations in the private sector, there are important implications for macroeconomic development, particularly in small open economies and/or countries that are members of a monetary union, such as those of the European Monetary Union. With the notable exception of the case of Sweden, opinion on this issue is still divided. In this paper, we look at public‐ and private‐sector wage interactions from an international perspective (18 OECD countries). We focus on the causal two‐way relationship between public and private wage setting, confirming that the private sector, on the whole, appears to have a stronger influence on the public sector, rather than vice versa. However, we also find evidence of feedback effects from public wage setting, which affect private‐sector wages in a number of countries. When the private sector takes the lead on wages, there are few feedback effects from the public sector, while public wage leadership is typically accompanied by private‐sector feedback effects.     

Continuity and Change in Australian Wages Policy

Australia shares with several small European economies the characteristic of having a relatively coordinated union movement with the ability to influence real wage levels. This article explores the course of wages policy over the last decade by applying to Australia a model of wage determination originating in Europe, a model which assumes that the union movement can determine the real wage level. The wage level the union movement chooses is influenced by choices it faces between real wage increases and employment growth. The unions are also influenced by the public sector employment generating activity of government. Stagflation in the late 1970s is analysed by hypothesising a misperception by the union movement of the policy options available to government, and a mistrust by government of the unions' willingness to moderate wage increases if employment levels rise rapidly. The model suggests that an accord between unions and government (such as that which has been in place in Australia since 1983) is a way to escape some of these policy dilemmas.     

Taxes,Strikes and Wages

A union and a firm bargain about wage increases. The firm possesses private information about its revenues. A two-period screening model is used to derive equilibrium wage demands by the union and to calculate measures of strike activity. Changes in wage demands and dispute probabilities due to alterations in various taxes are analysed. A more progressive income tax, a lower level of income taxes and higher payroll taxes reduce wages and strike activity. Hence, tax policy can be used not only to affect wages and employment, but lso to influence strike incidence.     

Factor‐biased public infrastructure and wage inequality

This paper analyzes how factor‐biased public infrastructure affects the skilled–unskilled wage inequality. In the basic model with a full employment economy, we find that when the weighted dependence of skilled labor and capital in the urban skilled sector on public infrastructure is large enough relatively to that of unskilled labor and capital in the urban unskilled sector, the wage inequality will be expanded. We also discuss labor‐biased and capital‐biased public infrastructure in our framework, and find that the relative dependences of relevant labor or capital on public infrastructure are important determinants of wage inequality. In the extended models, we analyze separately the issue of wage inequality in the economy with unemployment and the totally open capital market, and find the results of the basic model almost still hold.     

Increasing wage dispersion and the changes in relative employment and wages in Mexico's urban informal sector: 1987-1993

This study analyses the role of changes in informal/formal relative employment, wage levels and wage inequality in explaining increasing wage dispersion in Mexico during the 1987–1993 period. From 1987 to 1993, the variance of the log of hourly wages for Mexican workers increased by more than 50 per cent. Using data from the Encuesta nacional de empleo urbano we find that this increase in the overall wage dispersion was mainly driven by increasing wage dispersion in the formal sector coupled with a faster growth in formal sector employment as a percentage of total employment. However, compression in the distribution of wages within the informal sector contributed to substantially slowdown the increasing overall wage inequality. About 60 per cent of the 1987–1993 4.65 percentage point reduction in the informal sector share of total employment is explained by changes in the structure that determines sectoral employment; the rest is explained by changes in the composition of the labour force, particularly increases in the sectoral education gap and a change in the regional relative share of sectoral employment. Also, from 1987 to 1993 the sectoral wage ratio increased from 0.59 to 0.63. It seems that a relative improvement in unobserved skills in the informal sector helped to close the wage differential but this effect was partially offset by an increase in the relative prices of both observed and unobserved skills, as well as increases in relative observed skills in the formal sector, particularly education.     

Wage Inequality and Returns to Education in Turkey: A Quantile Regression Analysis

This paper investigates the male wage inequality and its evolution over the 1994–2002 period in Turkey by estimating Mincerian wage equations using ordinary least squares and quantile regression techniques. Male wage inequality is high in Turkey. While it declined at the lower end of the wage distribution it increased at the top end of wage distribution. Education contributed to higher wage inequality through both within and between dimensions. The within‐groups inequality increased and between‐groups inequality decreased over the study period. The latter factor may have dominated the former contributing to the observed decline in the male wage inequality over the 1994–2002. Further results are provided for the wage effects of experience, public sector employment, geographic location, firm size, industry of employment and their contribution to wage inequality. Recent increases in foreign direct investiment inflows, openness to trade and global technological developments are discussed as contributing factors to the recent rising within‐groups wage inequality.     

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.

Employment shifts, economic reform and the changes in public/private sector wages in Mexico: 1987–1997

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises, and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have important public policy implications since they suggest that public sector workers earn more and their wages have grown faster than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

Changes in the structure of earnings during the Polish transition

We document changes in the structure of earnings during the economic transition in Poland. We find that inequality in labor earnings increased substantially from 1988 to 1996. A common view is that the reallocation of workers from a public sector with a compressed wage distribution, to a private sector with much higher wage inequality, accounts for the bulk of increased earnings inequality during transition (see, e.g., the models of Aghion and Commander (1999) [Aghion, Philippe, Commander, Simon, 1999. On the dynamics of inequality in the transition. Economics of Transition 7, 275–2898.] and Commander and Tolstopiatenko (1998) [Commander, Simon, Tolstopiatenko, Andrei, 1998. The role of unemployment and restructuring in the transition. In: Commander, Simon (Ed.), Enterprise Restructuring and Unemployment in Models of Transition. The World Bank, Washington, pp. 169–192.]). However, our decomposition of the sources of the increase in inequality suggests that this compositional effect accounts for only 39% of the increase. Fully 52% of the increase is due to the increase in the variance of wages within sectors. That is, earnings inequality within both the private and public sectors grew substantially, and by similar amounts. This is consistent with prior work suggesting that even state-owned enterprises in Poland moved towards competitive wage setting as they restructured (see, e.g., Pinto et al. (1993) [Pinto, Brian, Belka, Marek, Krajewski, Stefan, 1993. Transforming state enterprises in Poland: evidence on adjustment by manufacturing firms. Brookings papers on Economic Activity, 213-70.] Commander and Dhar (1998) [Commander, Simon, Dhar, Sumana, 1998. Enterprises in the Polish transition. In Simon Commander (Ed.), Enterprise Restructuring and Unemployment in Models of Transition. The World Bank, Washington, pp. 109-142.]).A substantial part of the increase in earnings inequality was between group, due largely to increased education premiums. However, changes in inequality within education–experience–gender groups account for about 60 percent of the increase in overall earnings inequality. The increases in within-group inequality were very different across skill groups, with much larger increases for highly educated workers. These patterns hold in both the private and public sectors, although increases in education premiums were somewhat greater in the private sector.     

Wage differentials by sector and gender: a quantile analysis for the Spanish case

This paper analyses existing wage differentials between workers in the public and private sectors and by gender in Spain. This analysis is run throughout the entire earnings distribution and observed wage differentials are decomposed into a part explained by differences in productive characteristics and a part due to differences in returns to such characteristics. Our results show that public sector workers tend to earn higher wages than private employees, although most of this sector wage gap is due to better public workers’ productive characteristics. A wage premium in favour of men is also found in both the public and private sectors, with the gender wage gap greater at the top of the earnings distribution.
