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.     

Country characteristics and the incidence of capital income taxation on wages: An empirical assessment

This paper examines the incidence of corporate income taxes on wages using data from the US Bureau of Labor Statistics for 13 OECD countries. Within a wage‐bargaining framework, our econometric analysis shows that a substantial share of the corporate tax burden is shifted from capital to labour. However, the magnitude of this shift is influenced importantly by country characteristics affecting the process of wage determination, such as the degree of capital mobility, a country's relative influence over the world price of output and trade unions’ strength.     

A Regional Analysis of the Impact of Trade and Foreign Direct Investment on Wages in Mexico, 1984–2000

The conventional Heckscher–Ohlin model of trade predicts an equalizing effect of trade on wages in developing countries abundant in less‐skilled labor. Contrary to these predictions, skill premiums and skill demand increased in Mexico following trade liberalization. “New” trade theories have offered several channels through which trade can increase relative wages and demand for skilled workers. One such channel is foreign direct investment and outsourcing. Using the Mexican Household Income and Expenditure Survey (ENIGH) covering 1984–2000, the author examines the relationship between the demand for skill and maquiladora employment across regions and states. In contrast to previous studies based on manufacturing data for the 1980s, little evidence is found that growth in maquiladora employment is positively related to the increase in relative wages or wage‐bill share of more educated workers.     

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.     

Skilled Labour and International Specialisation in OECD Countries

Human capital and skilled labour are likely to become increasingly important determinants of industrial localisation. This paper calculates the factor content—the services of skilled labour, classified by level of education, embodied in trade in manufactures—for a sample of OECD countries in 1970–85. USA and Japan show a strong ‘revealed comparative advantage’ in human capital intensive production. In general, OECD countries where highly educated labour is abundant tend to specialise in and export skill intensive goods. Changes in the ranking with respect to specialisation in skill intensive goods, in particular the strong improvement of Japans' position, seem to be linked to different rates of accumulation of human capital.     

Some reflections on the growth of female labour supply and the tertiary sector

The economic literature on female participation in the labour market concentrates mainly on microeconomic supply decisions based on economic variables (wage rates, family income, human capital etc.) and maximization under external constraints (marriage, children), and on structural (demand) influences stemming from a growing service sector. The influence of non-economic cultural factors (‘feminist revolution’) is frequently mentioned but is usually treated - if at all - as a time trend. In the present paper difference in religious denominations are taken as a proxy for different feminist attitudes and are used in a cross-section analysis of 15 European countries. It is shown that a consideration of this factor has a significant effect on parameter values and on the perspective in which the growing share of women in total employment can be seen.     

R&D and manufacturing production specialization in developed economies

A study of the relation between technology and manufacturing production specialization in a series of developed economies is performed by means of models relating indicators of revealed symmetric comparative advantage of value added and exports to similar measures of comparative performance of R&D expenditure, capital intensity, total factor productivity and wage costs. The production and R&D specialization are shown to be substantial and sticky. This contrasts with the evidence of a substantial degree of convergence in the patterns of the other variables. Regression estimates show that, although all variables play their part, the impact of comparative R&D efforts on production specialization is by far the strongest. This impact is found to be stronger in the smaller economies and it is especially important in research-intensive industries. The influence of comparative wages is, moreover, found to be positive here, suggesting the dominance of a labour skill and efficiency wage effect over a wage cost competitiveness effect. These findings are shown to conform quite well with the predictions of Schumpeterian theory and of certain contributions to ‘new trade theory’ that have stressed the importance of dynamic economies of scale.     

The demand for skills and labour costs in partner countries

We analyse the consequences of trade integration in Europe (1995–2005) detecting how the labour costs in partner countries affect the domestic demand for high‐ and low‐skilled labour in ‘Old’ (EU‐15) and five ‘New’ EU member states. In general, independently of the skill level of workers, the results suggest complementarity between domestic and foreign labour. However, when we take into account the typology of sectors, the demand for the high skilled in low skill intensive sectors in ‘New’ EU members is boosted by the increase of the average labour cost in ‘Old’ EU members. Thus in low skill intensive sectors, the high skilled in ‘New’ member countries can substitute for employment in EU‐15 countries.     

Wage inequality and skill supplies in a globalised world

We investigate empirically, and explain theoretically, how the relative wages of skilled and unskilled workers vary with their relative supplies in open economies. Our results combine the insights of simple labour market and trade models. In countries that trade, relative wages respond inversely to variation in skill supplies, but the response decreases with the degree of openness to trade and is small in very open countries. To reconcile our results with standard estimates of the elasticity of substitution between skilled and unskilled workers, we allow also for the influence of directed technical change and income elasticity of demand for skill-intensive goods.     

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.     

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.     

Trade, technology, and unemployment: the role of endogenous skill formation

Abstract .  This paper analyses trade in an asymmetric  2 × 2 × 2  world, where the two countries ('Europe' and 'America') differ in their preferences towards wage inequality. Fair wage considerations compress wage differentials in both countries. European workers are more averse to wage inequality, and Europe is characterized by lower wage differentials and higher unemployment. Allowing for endogenous skill formation, the effects of a globalization shock, global technological change, and a change in the educational capital stock on skill premia and employment levels are derived. In contrast to a model with exogenous factor supplies, international wage and unemployment differentials are affected by global shocks.     

International trade,technological change and wage inequality in the UK economy

This paper examines the joint impact of international trade and technological change on UK wages across different skill groups. International trade is measured as changes in product prices and technological change as total factor productivity (TFP) growth. We take account of a multi-sector and multi-factor of production economy and use mandated wage methodology in order to create an well-balanced approach in terms of theoretical and empirical cohesion. We use data from the EU KLEMS database and analyse the impact of both product price changes and TFP changes of 11 UK manufacturing sectors on factor rewards of high-, medium- and low-skilled workers. Results show that real wages of skill groups are significantly driven by the sector bias of price change and TFP growth of several sectors of production. Furthermore, we estimate the share of the three different skill groups on added value for each year from 1970 to 2005. The shares indicate structural change in the UK economy. Results show a structural change owing to decreasing shares of low-skilled workers and increasing shares of medium-skilled and high-skilled workers over the years.     

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.     

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).     

An Empirical Analysis of Australian Labour Productivity

This study presents a model capturing sources of Australian aggregate labour productivity using annual time series data from 1970 to 2001. Labour productivity, or real output per hour worked, in this model is determined by real net capital stock in information technology and telecommunications (ITT), real net capital stock in the non-ITT sector, trade openness, human capital, the wage rate, international competitiveness, and the union membership rate. Given the lack of long and consistent time series data, multivariate cointegration techniques are inappropriate as the cointegration results will be sensitive to the lag length, the inclusion or exclusion of the intercept term or a trend in the cointegration equation and/or the vector autoregression (VAR) specification. Therefore, the Engle-Granger representation theorem and the Hausman weak exogeneity test have been employed to determine the short and long-term drivers of Australian productivity. Empirical estimates indicate that, in the long-term, policies aimed at promoting various types of investment, trade openness, international competitiveness, and the use of wage as a stimulant in a decentralised wage negotiation system, will improve labour productivity. In the short term, all the above variables except for human capital and labour reforms, which both need more time to evolve, determine productivity performance.     

Causal Relationships in Australian Wage Inflation and Minimum Award Rates*

When variables are correlated in time-series studies, it is often difficult to determine which is cause and effect, and in what sense. This paper applies multivariate time-series tests of causality to Australian wage, price, minimum wage award, labour demand and strike (working days lost) variables for 1953-76. The results provide tentative support for a model in which strikes are exogenous:the size of Arbitration Commission awards is determined by strikes (suggesting that a trade union capture theory of Arbitration Commission regulation may apply):money wages are determined by minimum wage awards; and the demand for labour variable (measured in this paper by the ratio of actual to potential output) is determined (in a negative relationship) by money wages.     

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.     

Greenfield FDI and skill upgrading: A polarized issue

Outbound FDI is often accused of increasing income inequality in developed countries by shifting labour demand from low‐skilled towards high‐skilled workers (wage polarization). In response, we employ data on greenfield FDI that, in contrast to M&As, may be more clearly linked to skill upgrading. Our data also delineate greenfield FDI by sector, function and destination, allowing us to control for different motives and skill intensities for 17 developed countries for 2003–2005. We find that greenfield FDI in support services, e.g., back and front office services, induces polarized skill upgrading, benefitting high‐skilled workers at the expense of medium‐skilled workers, thereby polarizing wages.     

Skills,Tasks and the Scarcity of Talent in a Global Economy

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low‐skilled and high‐skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the productivity advantage of high‐skilled workers in the performance of complex tasks. I study the firms’ assignment problem under two labor market regimes, which capture the polar cases of fully flexible wages and a binding minimum wage for low‐skilled workers. Since the minimum wage lowers the skill premium, it increases the range of tasks performed by high‐skilled workers, which enhances the stock of knowledge within firms to solve complex tasks and reduces the mass of active firms. In a setting with fully flexible wages trade does not affect the firm‐internal assignment of workers to tasks. On the contrary, if low‐skilled wages are fixed by a minimum wage, trade renders high‐skilled workers a scarce resource and reduces the range of tasks performed by this skill type with negative consequences for the human capital stock within firms. In this case, trade leads to higher per‐capita income for both skill types and thus to higher welfare in the open than in the closed economy, whereas – somewhat counter‐intuitive – inequality between the two skill types decreases, as more low‐skilled workers find employment in the production process.
