Shocks and rigidities as determinants of CEE labour markets’ performance

In this article, the impact of real wage, productivity, labour demand and supply shocks on eight Central and Eastern European (CEE) economies from 1996–2007 is analysed with a panel structural vector error correction model. A set of long‐run restrictions derived from the dynamic stochastic general equilibrium (DSGE) model is used to identify structural shocks, and fluctuations in foreign demand are controlled for. We find that the propagation of shocks on CEE labour markets resembles that found for OECD countries. Labour demand shocks emerge as the main determinant of employment and unemployment variability in the short‐to‐medium run, but wage rigidities were equally important for observed labour market performance, especially in Poland, Czech Republic and Lithuania. We associate these rigidities with collective bargaining, minimum wage, active labour market policies and employment protection legislation.     

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.

The NAIRU reconsidered: why labour market deregulation may raise unemployment

According to the mainstream theory of equilibrium unemployment, persistent unemployment is caused mainly by ‘excessive’ labour market regulation, whereas aggregate demand, capital accumulation and technological progress have no lasting effect on unemployment. We show that the mainstream non‐accelerating inflation rate of unemployment (NAIRU) model is a special case of a general model of equilibrium unemployment, in which aggregate demand, investment and endogenous technological progress do have long‐term effects. It follows that labour market deregulation does not necessarily reduce steady‐inflation unemployment. Theoretically, if the decline in real wage growth claims owing to deregulation is smaller than the ensuing decline in labour productivity growth and in the warranted real wage growth, then in that case steady‐inflation unemployment may increase. Empirical evidence for 20 Organisation for Economic Cooperation and Development (OECD) countries (1984–1997) indicates that the impact of labour market deregulation on OECD unemployment is zero, and possibly negative (causing a higher rate of unemployment).     

Labour Demand, Wage Mark-ups and Product Market Integration

Globalization makes it easier to relocate production and thus employment across countries. Therefore, it is often asserted that labour demand becomes more elastic, causing wage mark-ups to fall and thus erode the effective market power of trade unions. We explore this issue in a general equilibrium model where the elasticity of labour demand is endogenized and related to the facility by which production can be relocated across countries. Wages and employment increase unambiguously as a result of product market integration, but it is ambiguous whether wage mark-ups decrease or increase. A numerical illustration suggests that the elasticity effect – even when the wage mark-up falls – is of second order relative to the gains from trade.      

Looking back, looking ahead: Biased technological change, substitution and the wage gap

The implications of ICT on wage inequality are studied by applying a CES production function with skilled and unskilled labour. Skill-biased technological change increases wage inequality. The result is reinforced in a two-sector general equilibrium model if the income elasticity of the demand for high-tech goods and the elasticity of substitution between final goods are larger than one.     

Institutions,capital stock and wage setting in Spain

This article confronts two distinct perspectives of the labour market: the institutionalist view?–?highlighting equilibrium and labour market institutions?–?and the Chain Reaction Theory?–?emphasizing dynamics and the growth drivers’ role in labour market performance. We consider the ratio of public to private capital stock as a growth driver relevant to the labour market; provide different economic rationales for this ratio to exert a negative influence in wage setting; and explore its empirical relevance in the context of a wage setting curve for Spain comprising the standard variables. There are two main results. First, several institutional variables taken to be critical to explain unemployment in the mainstream literature are not relevant for the Spanish wage setting curve. Second, there is a negative and significant influence of the ratio of public to private capital stock, which is robust to different specifications of the wage setting equation.     

Skilled–unskilled wage inequality: A general equilibrium analysis

The paper develops a static three sector competitive general equilibrium model of a small open economy in which skilled labour is mobile between a traded good sector and a non-traded good sector and unskilled labour is specific to another traded good sector. The capital is perfectly mobile among all these three sectors. We examine the effects of change in different factor endowments and of globalization on skilled–unskilled wage inequality. We find that the effect of a change of a factor endowment on wage inequality depends on the factor intensity ranking between two skilled labours using sectors and on the relative strength of the marginal effects on demand for and supply of non-tradable good. We also find that a decrease in the price of the product produced by skilled (unskilled) labour using traded good sector lowers (raises) the skilled–unskilled wage inequality.     

Skilled–unskilled wage inequality,nontraded good and endogenous supply of skilled labour: A theoretical analysis

The paper develops a static four sector competitive general equilibrium model of a small open economy in which skilled labour is endogenously produced by the education sector and is mobile between a traded good sector and a nontraded good sector. Capital is also perfectly mobile among the education sector, skilled labour using traded good sector and the nontraded good sector. However, land and unskilled labour are specific to another traded good sector. We analyse the effects of change in different factor endowments and reduction in tariff rate on skilled–unskilled wage inequality. We find that the effect of a change in different parameters on wage inequality depends on the factor intensity ranking between two skilled labour using sectors and on the relative strength of the marginal effects on demand for and supply of nontraded final good. We also analyse the effects of changes in different parameters on the supply of skilled labour.     

The impact of labour unions on external auditor selection and audit scope: evidence from the Korean market

We examine whether labour unions influence external auditor selection and audit scope. As a major user group of financial information, labour unions likely demand financial information of high quality and thus high-quality audits. As a union’s request for wage increases is likely strong when a firm is performing well, management facing wage negotiations with the labour union has incentives to manipulate earnings downward and may therefore prefer auditors who allow more discretion. Using union data unique to Korea during 2005–2008, we find that firms with a stronger labour union tend to choose higher-quality auditors (i.e. Big N or industry specialist auditors). We also find that unionization is negatively (positively) associated with positive (negative) abnormal audit fees and audit hours, and the effects are more pronounced when the union is stronger and more active. Given that departures from normal audit fees and audit hours in either direction arguably impair audit quality, this finding is consistent with our prediction of unions’ demand for high-quality audits. Overall, our findings suggest that labour unions play an important role in determining audit quality.     

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.     

WHAT CAN CHANGES IN STRUCTURAL FACTORS TELL US ABOUT UNEMPLOYMENT IN EUROPE?

This paper examines the impact of temporal variation in labour market institutions and other structural factors on unemployment in Europe. A system comprising a labour demand and a wage equation is estimated on pooled time‐series data for the six largest EU countries for the 1980s and 1990s. The results suggest that changes in regional mismatch, trade union density and the ratio between consumer and producer prices are positively associated with structural unemployment. This result is robust to a wide variety of different specifications. No consistent role is found for other institutional factors (such as social security benefits, employment security and minimum wage).     

Multinational companies, backward linkages, and labour demand elasticities

Abstract .  This paper investigates the link between nationality of ownership and wage elasticities of labour demand at the level of the plant. In particular, we examine whether labour demand in multinationals becomes less elastic with respect to the wage if the plant has backward linkages with the local economy. Our empirical evidence, based on a rich plant level dataset, shows that the extent of local linkages does indeed generally reduce the wage elasticity of labour demand. This result is economically important and holds for a number of different specifications.     

Why has wage inequality increased more in the USA than in Europe? An empirical investigation of the demand and supply of skill

During the past two decades the wage gap between high and low skill labour has increased more in the USA than in many European countries. In this paper, the correspondence between occupation and education is used to construct aggregates of skill supply, skill demand and unemployment by skill group that are comparable across countries. Using individual data for years 1983–1994, it is found that the relative demand for skilled labour has increased to a similar extent in the USA and in Europe and that wage inequality remained low in Europe partly because the European relative supply of skill increased much faster than in the USA, and partly because European relative wages were rigid, which caused an increase in unemployment among the low-skilled.     

Trade Unions in an Open Economy: A General Equilibrium Analysis*

This paper derives a general equilibrium demand-for-labour schedule within the Heckscher-Ohlin-Samuelson model of a large open economy, and then introduces an economy-wide labour union that maximizes its utility subject to this demand schedule, thereby determining the real wage and hence total employment A parametric shift's comparative-static effects on the equilibrium levels of unemployment and welfare are analyzed within this fully unionized economy.     

An approach to the wage level determination for a developing economy

The purpose of this paper is to investigate the factors determining wage and salary rates in Greek manufacturing. The model used originates from a derived demand for, and a supply of, labour. The wage equation is a theoretical long-run relationship. Because in the short-run disequilibria occur we develop an adjustment process whereby wage-rates in the short-run adjust to the long-run factors. The statistical estimates reveal that in this determination employment can be used as a proxy of product demand. This is due to the fact that in developing economies the increasing size of the product market determines employment. It is shown, moreover, that the use of productivity for the formulation of an incomes policy entails large wage-rates differentials, but due to the existence of a wage transfer mechanism wage-rates and salary-rates move upwards in unison.     

The role of the wage-productivity gap in economic activity

This paper argues that wages lagging behind productivity is a long-run structural phenomenon due to the interplay of wage dynamics and productivity growth. We call this interplay frictional growth, a term that can only be nullified in the utopian case of zero growth and/or no dynamics. In that vein, we challenge the prevailing view of the neutrality of the labour income share and investigate its impact on the evolution of employment. We thus estimate wage setting and labour demand equation systems – for France, Germany, Italy, Japan, Spain, the UK, and the US over the 1960–2008 period – and find that the labour share is negatively associated with employment even when the conventional assumption of a unitary long-run elasticity of wages with respect to productivity holds. Acknowledging the presence of the wage-productivity gap in both the short and long run, this work stands as the building block for assessing the effect of the falling labour share on economic activity. As recent work has shown that the widening wage gap is also an important factor prompting inequality, it can be argued that by supporting employment the falling labour share ‘sweetens’ the impact of rising income inequality, and, as such, deserves the attention of policy makers.     

How Does Uncertainty about Future Fiscal Policy Affect Current Macroeconomic Variables?

A dynamic stochastic general equilibrium macromodel is constructed, based on infinitely lived, dynamically optimising households with labour market monopoly power. Randomness in future government spending causes randomness in the future output and price levels, both when the money wage is flexible and when it is set one period in advance. We show that, through three different mechanisms, rational anticipation of this depresses current aggregate demand. If the wage is preset, it thereby also depresses current output. Such fiscal uncertainty is suggested as one possible explanation for the faltering of the economic recovery in Europe in 1995 and 1996.     

Labour Demand and Wage-induced Innovations: Evidence from the OECD countries

This paper shows that increasing real wages steepens or reverses the slope of the labour demand schedule because increasing wages give firms incentives to innovate and to invest in newer and more efficient vintages of capital. Using macroeconomic data for the OECD countries it is shown that the efficiency inducement of higher real wages steepens the traditional neoclassical labour demand function substantially. Taking into account the adverse demand effects of wage reductions it is doubtful that real wage reductions are a cure for the unemployment problem in the OECD countries.     

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.     

The estimation of a disequilibrium real wage equation for Britain

An aggregate wage equation is formulated based on a disequilibrium labor market model. The specification allows for an important special case to be tested, namely the equilibrium hypothesis that real wages move instantaneously to equate the demand for and supply of labor. The hypothesis that the British labor market has been in equilibrium is rejected. The adjustment path for real wages is monotonic and dominated by demand factors. Real wages move quickly to eliminate excess demand but the results contradict the monetarist contention that the aggregate labor market is continuously in a temporary, if not full, equilibrium.
