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.     

Wage and employment effects of a wage norm

Most transition countries used tax‐supported wage norms in the early 1990s, as a part of their market liberalization programmes. This article analyses how a firm‐level tax (or subsidy) on deviations from a pre‐set wage norm may promote employment by rotating the labour demand curve perceived by the workers’ union around the value of the norm. We derive the conditions under which it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labour demand curve and the role of the tax rate on its slope.     

Labor taxation, public finance, and wage determination: evidence from OECD countries

This paper analyzes the relationship between unemployment, average effective labour tax rates and public spending in 17 OECD countries. The focus is on the degree of centralization and cooperation in wage setting. Estimation results from a dynamic time-series-cross-section model suggest that the countries where wage setting takes place at the firm level have used labour taxes less extensively in financing welfare spending, compared to countries with centralized or decentralized bargaining. This is consistent with another finding, according to which labour taxes distort the labour demand the least in the countries with firm level bargaining.     

Multinationals,cross‐border acquisitions and wage dispersion

Abstract We examine the impact of cross‐border acquisitions on intra‐firm wage dispersion using a detailed Swedish linked employer‐employee data set including data on all firms and about 50% of the Swedish labour force with information on job‐tasks and education. Foreign acquisitions of domestic multinationals and local firms increase wage dispersion but so do also other types of cross‐border acquisitions. Hence, it is the acquisition itself rather than foreign ownership that increases wage dispersion. The positive wage effect is concentrated to CEOs and other managers, whereas other groups are either negatively affected or not affected at all.     

Child labor,urban proximity,and household composition

Using detailed survey data from Nepal, this paper examines the determinants of child labor with a special emphasis on urban proximity. We find that children residing in or near urban centers attend school more and work less in total but are more likely to be involved in wage work or in a small business. The larger the urban center, the stronger the effect is. Urban proximity is found to reduce the workload of children and improve school attendance up to 3 h of travel time from the city. In areas of commercialized agriculture located 3 to 7 h from the city, children do more farm work. Urban proximity effects are accounted for by a combination of local labor supply and demand conditions, most notably the local importance of agriculture, the education level of the parents, and the local wage rate. Child servants, which represent a small proportion of all children, work much harder than other children and appear particularly at risk.     

Entry Deterrence in a Unionized Oligopoly

We investigate wage determination between an incumbent firm and its labour union under threat from another firm entering its product market. In equilibrium, it may be optimal for a labour union of the incumbent firm to lower its wage demand. This may make it possible for the incumbent firm to maintain a higher employment level, in that the lower wages can help the firm deter the entry of a rival firm. This will yield a higher profit for the incumbent firm and a lower utility level for the labour union compared with those in an equilibrium with no threat of entry.

Gender Roles,Occupational Choice and Gender Wage Differential*

This paper addresses the impact of occupational choice and the perception of gender roles on the gender wage differential. We examine the effect of occupational choice upon the level of wages and investigate the determinants of occupational choice. The evidence supports earlier findings that the wage differential is caused by demand discrimination within occupations. We also conclude that if females had a less traditional attitude towards their role in the labour market they would generate an occupational distribution that would produce a higher wage     

Offshoring, labour market institutions and the elasticity of labour demand

This paper analyses the evolution of the elasticity of labour demand and the possible role of offshoring therein using industry-level data for a large number of OECD countries. The first main finding is that the wage elasticity of labour demand has increased substantially since 1980, although some of this increase may reflect a trend increase in the speed of adjustment rather than an increase in the long-run wage elasticity. The evidence on the potential contribution of offshoring to raising labour demand elasticity is mixed. No association is found between increases in offshoring and demand elasticity during the second half of the 1990s, but there is a significant cross-sectional association between higher average offshoring intensity during this period and higher demand elasticity. We also find some evidence that strict employment protection legislation weakens the cross-sectional association between offshoring and higher labour demand elasticity, suggesting that the relationship between offshoring and the labour demand elasticity may depend on the national institutional environment.     

Product cycles, endogenous skill acquisition, and wage inequality

Abstract .  This paper presents an endogenous product cycle overlapping generations model, where the supply of skilled labour is endogenously determined. This is used to examine how production shifts through imitation by developing countries affect the domestic wage differential and supply of skilled labour in developed countries. In the model, production shifts increase the demand for researchers in developed countries and cause higher relative wages for skilled labour: this leads to more individuals acquiring the skills. As a consequence, the model helps to explain the simultaneous increase in the domestic wage gap and in the supply of skilled labour observed in developed countries.     

A dynamic spatial panel data approach to the German wage curve

A wage curve is a decreasing function of wages on the regional unemployment rate. Most empirical studies on the wage curve ignore possible spatial interaction effects between the regions which are the primary units of research. This paper reconsiders the western German wage curve with a special focus on the geography of labour markets. Spillovers between regions are taken into account. The paper tests whether the unemployment rate in the larger surrounding region also affects wages. In addition, agglomeration effects and effects of local monopsony are assessed.The main database is a random sample of 974,179 employees observed over the period 1980-2004 and covering 326 NUTS3 units (districts). This rich data set is used to estimate a dynamic wage curve according to the two-step approach of Bell et al. (2002). In the first step one controls for individual heterogeneity and in the second step one allows for spatial effects of unemployment across regions on wages. We check the sensitivity of this wage elasticity to various spatial weight matrices as well as allowing for the endogeneity of unemployment. We also estimate the wage elasticity for various population groups.     

Real Wages,Demand and Employment in the UK 1921–1938: A Disaggregated Analysis

This paper uses the Layard and Nickell model of the labour market to examine the determinants of employment at a sectoral level for the interwar UK economy. Sectoral level data permits examination of the differing responses to changes in the determinants of employment. Estimation of employment functions indicates significant elasticities with respect to aggregate demand variables across a wide range of sectors but less support for a negative real wage effect, particularly in those industries responsible for major losses in employment. The evidence is therefore more consistent with the low-aggregate-demand explanation of labour market behaviour than it is with the high-real-wage hypothesis.     

Labour mobility during transitionEvidence from Georgia1

This article deals with labour mobility in Georgia during economic transition. We use quarterly 1998–99 panel data to examine mobility across six labour market statuses (inactivity, unemployment, formal wage employment, informal wage employment, self‐employment and farming). Our findings are consistent with the hypothesis of labour market segmentation. Formal employment is preferred to informal employment. Unemployment is largely a queuing device for individuals with higher education waiting for formal jobs. Some self‐employment is subsistence activities and consistent with a segmented labour market, while other is high risk and potentially high return activities. Age, gender and education are significant determinants of labour mobility. Finally, informal employment serves as a buffer in times of recession – with farming and informal wage employment absorbing labour shed by other statuses during the Russian financial crisis.     

Trade and technological explanations for changes in sectoral labour demand in OECD economies

This paper sets out to establish the main determinants of variations in the demand for aggregate labour in manufacturing and service sectors (22) for a cross-section of OECD countries (14). A relatively new panel data set is employed in the analysis, the OECD's International Sectoral Data Base. Preliminary analysis revealed that the ‘within’ sector variation in the wage share dominated overall variation for most countries and time periods. A separate dynamic model was thus generated to explain the ‘within’ sector variation in the wage share. This model contained real wages, output, the capital stock, technological change (total factor productivity) and trade (the imports to value-added ratio) as independent variables. In addition the wage level was also interacted with these explanatory variables on the presumption that skill is positively correlated with the level of wages. Because of the potential for simultaneity bias, estimation was conducted by IV and OLS. The main findings were that the capital stock and technological change were the main determinants of shifts in labour demand. While some countries reported the trade variable as significant its influence was only of slight importance in most cases. The interaction terms proved to be significant in a large number of countries. Some evidence was found that capital and technological were complementary with skill. Overall it was found that broad agreement existed across countries in the factors which influence labour demand despite considerable differences in the cross-country nature of labour market institutions.     

Female labour force participation in an era of organizational and technological change

Abstract The supply of skilled female labour increased significantly at the beginning of the twentieth century as women assumed positions in the newly created clerical workforce. Evidence suggests that despite this increase in labour supply, the wage paid to female clerical workers increased over the period and that the ratio of female clerical wages to male manufacturing wages was roughly constant. These labour market facts can be accounted for in a dynamic general equilibrium model in which an exogenous increase in human capital induces an increase in demand for skilled clerical workers. While induced technological change that favours skilled workers may account for the observed increase in female real wages, explaining the stagnate relative weekly wages paid to female clerical workers requires a framework that includes organizational change.     

Labour Quality and Wage Differentials

This paper presents a quality theory for labour. Analytical solutions for the equilibrium demand for labour quality equation and the equilibrium wage equation are computed. Wage differentials can be explained by variations in labour quality. A method that yields consistent estimates for all the parameters of the equilibrium demand for labour quality equation, the labour quality index equation, and the equilibrium wage equation is also presented. To illustrate the methodology an application is presented that focuses on the market for seminars and the wages and quality characteristics of trainers.     

Exporting and labour demand: Micro‐level evidence from Germany

It is widely believed that globalization increases the extent of employment and wage responses to economic shocks. In this paper, we investigate the effect of firms’ exporting activities on the wage elasticity of labour demand. Using rich, administrative linked employer–employee panel data from Germany and destination‐specific industry‐level information on trade flows, we explicitly control for self‐selection into exporting and endogeneity concerns. Overall, we find that exporting has a significant positive effect on the (absolute value of the) unconditional wage elasticity of labour demand. In line with our hypothesis, we further show that the effect is particularly strong for those plants that export a significant share of their output to low‐ and medium‐income countries, hence face relatively more price‐elastic product demand.     

Equilibrium unemployment with outsourcing and wage solidarity under labour market imperfections

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high- and low-skilled workers. When the labour union adopts a solidaristic wage policy, it will dampen this tendency. Further, higher outsourcing will increase equilibrium unemployment among the high-skilled workers, whereas it will reduce it among the low-skilled workers. Overall, outsourcing will reduce economy-wide equilibrium unemployment under the reasonable condition that the proportion of high-skilled workers is sufficiently low.     

The Determinants of Relative Wage Change in Australia

This article uses data from 3500 Australian workers to investigate which factors have had a significant influence on microeconomic wage growth over the years 1997 to 2000. The relative importance of four types of factors—outside incomes, demand for labour, workers' relative bargaining strength and category of wage contract—are compared. Basic individual demographic characteristics and some indicators of workers' bargaining power provided most of the explanation for wage changes. Proxy variables for labour demand, while significant and correctly signed, were small in magnitude.     

Labour Utilization and Wage Inflation in Australia: An Empirical Examination*

This paper tests the hypothesis that the level of labour utilization within the firm should be substituted into the Phillips Curve in place of traditional measures of excess demand. Gregory and Smith (1983) proposed overtime hours as a proxy for labour utilization within the firm. For various reasons we prefer the deviation from trend in hours worked. The results support the underlying hypothesis, and add strength to the view that to understand the process of wage inflation at the macro level we must examine the utilization of labour at the micro level of the firm.     

Wage,foreign-owned firms,and productivity spillovers via labour turnover: a non-linear analysis based on Chinese firm-level data

Using firm-level panel data from Chinese manufacturing firms over the period 2004–2007, this article investigates the impact of the wage gap between local and foreign-owned firms on foreign direct investment (FDI) spillovers in terms of total factor productivity (TFP). We find a non-linear threshold effect that: a low-level wage gap threshold exists, below which FDI spillovers are significantly negative. This is because FDI spillovers via labour turnover are blocked due to the low wages of local firms, which jeopardizes the flow of skilled workers from foreign firms to local firms. In contrast, when the wage gap reaches a high-level threshold, local firms can get benefits from FDI spillovers. The reason is that high wages of local firms attract skilled employees to leave foreign firms, which yields a large magnitude of worker mobility from foreign firms to local firms. Our article provides evidence that labour turnover as the channel of FDI spillovers only works when the wage gap is beyond some threshold. Also, these thresholds vary across regions and firm ownerships.
