The role of unit labor costs in African manufacturing investment and export performance

Several studies have pointed out that manufacturing wages are relatively higher in African countries than in other countries at similar levels of development, and that this contributes to the continent's lower levels of manufacturing competitiveness. This paper derives unit labor costs (ULCs)—average wages relative to productivity—for two-digit manufacturing sectors across a sample of 79 developed and developing countries, including 13 African countries, over the 1990–2015 period. We benchmark the ULCs to China and estimate the relationship between relative ULCs and manufacturing sector investment rates and export performance. We find that relative ULCs have a smaller association with exports in Africa relative to other developing regions. There is some evidence that investment responds to changes in relative ULCs in Africa; however, the estimated effects are smaller than in the full sample. Further, we find that for Africa, the level of labor productivity has a quantitatively stronger and more robust association with manufacturing performance than the level of real wages. The results have important implications for industrial policy in African countries.     

The productivity-wage and productivity-employment nexus: a panel data analysis of Indian manufacturing

This article investigates the long-run relationship between labour productivity and employment, and between labour productivity and real wages in the case of the Indian manufacturing sector. The panel data set consists of 17 two-digit manufacturing industries for the period 1973–1974 to 1999–2001. We find that productivity-wages and productivity-employment are panel cointegrated for all industries. We find that both employment and real wages exert a positive effect on labour productivity. We argue that flexible labour market has a significant influence on manufacturing productivity, employment and real wages in the case of Indian manufacturing.     

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.     

RISING WAGES: HAS CHINA LOST ITS GLOBAL LABOR ADVANTAGE?

We document dramatic rising wages in China for the period 1978–2007 based on multiple sources of aggregate statistics. Although real wages increased seven‐fold during the period, growth was uneven across ownership types, industries and regions. Over the past decade, the wages of state‐owned enterprises have increased rapidly and wage disparities between skill‐intensive and labour‐intensive industries have widened. Comparisons of international data show that China's manufacturing wage has already converged to that of Asian emerging markets, but China still enjoys enormous labour cost advantages over its neighbouring developed economies. Our analysis suggests that China's wage growth will stabilize to a moderate pace in the near future.     

The dynamics of financial development,globalisation, economic growth and life expectancy in sub‐Saharan Africa

The importance of life expectancy is recognised in the development economics literature because of its increasing effects on labour productivity and economic growth in long‐run. However, no published study to date empirically examines the nonlinear relationships between globalisation, financial development, economic growth and life expectancy in sub‐Saharan African (SSA) countries. Therefore, our study intends to fill this gap by using non‐parametric cointegration test and multivariate Granger causality test towards a non‐linear empirical understanding of the factors affecting the life expectancy. We consider the case of 16 sub‐Saharan African economies using annual data over the period 1970–2012. The empirical analysis indicates that financial development, globalisation and economic growth appear to have a positive impact upon life expectancy in sub‐Saharan African economies, except for Gabon and Togo. Our empirical findings may provide insightful policy implications towards improving population health conditions which are vital for promoting the productivity of labour force and long‐run economic growth in sub‐Saharan African countries. In light of these policy implications, governments should incorporate globalisation, financial development and economic growth as key economic instruments in formulating sustainable developmental policy to promote life expectancy for the people in sub‐Saharan African countries.     

Picking “Lemons” or Picking “Cherries”? Domestic and Foreign Acquisitions in Norwegian Manufacturing*

We compare the performance in employment, wages and productivity for domestic plants acquired by new domestic and foreign owners. Prospective foreign owners pick large, high‐wage, high‐productivity plants, while new domestic owners choose average performers of above‐average size. Employment, labour productivity, and total factor productivity decline in domestic acquisition targets before acquisitions; only wages recover afterwards. Employment, wages and labour productivity increase after foreign acquisitions. The sample selection introduced by long‐term comparisons and a focus on unique events introduces a downward bias into the results for domestic acquisitions and an upward bias for the foreign acquisitions.     

The Impact of Company Human Resource Policies on Social Skills: Implications for Training Sponsorship, Quit Rates and Efficiency Wages

The concept of a firm's human capital is reconsidered to include both the technical and the social skills of its workforce. Technical skills are defined by the ability to turn inputs into outputs, and measured by the productivity of unit labour effort. Social skills are defined by the propensity to behave in a manner conducive to the firm's objectives. In other words, social skills are constituted as the norm of effort contribution to which an individual assents, and are measured by observed motivation and behaviour. The existence for firms of a labour management function is proposed and supported, relating social skills to human resource policies. Implications for the labour market are that: (i) firms pay for general training and, at the same time, wages do not necessarily increase with training; (ii) human capital acquisition may not lead to an increase in quitting, even controlling for wages; (iii) human resource policies substitute for efficiency wages or for employee monitoring; and (iv) economies with high organisational commitment have low equilibrium unemployment rates.     

Cointegration Tests of the Profit-maximising Equilibrium in Greek Manufacturing: 1958–91

This paper applies the recently developed cointegration techniques to test for a long-run equilibrium among real wages and the average productivity of labour as implied by profit maximisation in the Greek manufacturing sector. We find evidence for a profit-maximising equilibrium and for adjustment towards this long-run equilibrium through nominal wages and labour productivity. We have also provided an estimate of the elasticity of substitution of 0.23 which is consistent with that of other studies using alternative approaches.     

Prices,Productivity and Wage Bargaining in Open Economies*

According to the standard union bargaining model, unemployment benefits should have big effects on wages, but product‐market prices and productivity should play no role in the wage bargain. We formulate an alternative strategic bargaining model, where labour and product‐market conditions together determine wages. A wage equation is derived and estimated on aggregate data for four Nordic countries. Wages are found to depend not only on unemployment and the replacement ratio, but also on productivity, international prices and exchange rates. There is evidence of considerable nominal wage rigidity. Exchange rate changes have large and persistent effects on competitiveness.     

Structure and performance of the service sector in transition economies1

This paper examines the performance of the service sector in the Eastern European transition economies during the 1997–2004 period. The performance of the service sector as a whole and of its sub‐sectors is very heterogeneous within the region. Service sub‐sectors that are information and communications technology producers or users and those using skilled labour more intensively exhibit the highest labour productivity growth. Our estimates show a positive and significant effect of liberalization on service labour productivity growth that is stronger for sub‐sectors that are more distant from the technological frontier. Service liberalization is also shown to have a positive effect on labour productivity levels and growth of downstream manufacturing industries.     

The Beveridge curve and labour market dynamics in Turkey

This article investigates the dynamics of unemployment and vacancy rates in Turkey during the period 1951 to 2008 by means of a Beveridge Curve (BC). The time-series analysis of unemployment and vacancies as well as two other relevant labour market variables, real wages and real labour productivity, strongly suggests inefficiency in the Turkish labour market. A stable long-run relationship between unemployment rate and vacancy rate is found for Turkey, that is, the existence of a negatively sloped BC is verified. The estimated Turkish BC reflects the structural problems and lack of flexibility in the labour market. The modified BC with real wages and labour productivity reveals that labour productivity has no significant effect on unemployment rate whereas wages have positive and significant effects on the same variable.     

The optimality and overuse of labour in Estonian manufacturing enterprises*

Transition economies need labour market flexibility for successful restructuring and reallocation of the labour force, and for coping with the requirements of the European Monetary Union. In this paper we apply a novel approach to the issue of labour market flexibility in transition countries by studying the optimality and efficiency of labour usage in Estonian manufacturing enterprises. We employ a dynamic model in which both the long‐run optimal level of employment and the speed at which actual employment is adjusted to the optimal are modelled as functions of several variables. Firm‐level panel data of 1995–99 were used. The results showed that in the long run, employment responds most strongly to wages, followed by value added and capital stock. The speed of adjustment, labour use optimality and efficiency all show much greater variations over firms than over time. In the course of time, both labour‐saving technical change and an increase in the efficiency of labour usage occur. On average, there is shortage of labour compared to firms’ own optimal level, along with overuse of labour compared to best‐practice technology. Capital seems to be a binding constraint on the development of employment in the Estonian labour market.     

Schumpeterian and semi‐endogenous productivity growth explanations

This paper examines the nature and sources of productivity growth in South African manufacturing sectors, from an international comparative perspective. On panel data estimations, we find that the evidence tends to support Schumpeterian explanations of productivity growth for a panel of countries including both developed and developing countries, and a panel of South African manufacturing sectors. By contrast, semi‐endogenous productivity growth is supported for a panel of OECD (Organisation for Economic Cooperation and Development) manufacturing sectors. However, we also report evidence that suggests that sectors are not homogeneous. For this reason, time series evidence may be more reliable than panel data. Time series evidence for South Africa suggests that prospects for the sustained productivity growth associated with Schumpeterian innovation processes, is restricted to a narrow set of sectors. For the OECD manufacturing sectors, both semi‐endogenous and Schumpeterian growth finds support. Schumpeterian growth is present for a larger number of sectors than for South Africa, and is most prevalent in the North American economies.     

The driving forces behind China’s growth1

The main objective of this article is to disentangle the determinants of the Chinese economic growth that occurred from 1965 to 2000. We have explored, first, the time series properties of the growth rates of gross domestic product and labour productivity with an extended battery of unit‐root tests. Then, in a multivariate setting, we use the VAR model methodology to provide evidence that physical and human capital accumulation, R&D expenditure, openness and competitiveness are the main drivers of output, labour productivity and total factor productivity growth in the long run. Additionally, we also show that although China has not yet converged to its long‐run equilibrium, it is in the process of catching up. These results are more consistent with some versions of the endogenous growth models than with Solow‐type models of growth, since they support active strategies of economic policy to stimulate economic growth and catching up with more advanced economies.     

Are wages and productivity converging simultaneously in Euro-area countries?

A convergence analysis is applied to wages and productivity for Euro-area countries in the period from 1981 to 2001. The results show a reduction in the dispersion of wages and unit labour costs, but not in productivity. Different patterns are found for real and nominal wages: higher levels of inflation in countries with higher growth rates of unit labour costs have caused nominal wages to move towards equalization. Moreover, disparities in all the variables have remained more or less the same since 1997, suggesting that the establishment of a single currency area has not accelerated the process of wage equalization.     

Convergence and growth. Labour productivity dynamics in the European Union

This paper investigates labour productivity dynamics for 1263 regional economies of the European Union during 1991–2007. Despite convergence is usually found to occur conditionally to economy-wide factors, results reveal a clear process of unconditional convergence for financial and business-related market services. Such an evidence is not found for manufacturing and aggregate productivity, for which long run distribution dynamics are characterized by bimodality. The decomposition of the growth rate of aggregate labour productivity reveals that pure productivity gains drive growth. Structural change plays a minor role in the process, however it halves the contribution of the manufacturing sector for the richest regions, while it enhances the weight of financial market services.     

Monopolistic wages or efficient contracts?

Using a representative sample of medium and large firms, this paper explores the process of employment and wage bill determination in the Bulgarian manufacturing sector. The results suggest that, during 1997–2001, the labour market behaviour of these firms was consistent with weakly efficient contracting and employment elasticity with respect to both sales and wages similar to that of the fastest‐reforming Central and Eastern Europe economies. Although a case study using data on sell‐off deals by the Privatization Agency suggests that the largest firms selected for cash privatization may have exhibited higher preference for wage enhancement than employment protection, the results do not bring into question the efficient performance of the post‐crisis labour market in Bulgaria. Importantly, the study rejects the hypothesis that either persistent government stakes or mass privatization may have led to efficiency deterioration.     

Determinants of labour productivity: Comparison between developing and developed countries of Asia‐Pacific

The current study investigates the trends in labour productivity of the major developing and developed economies of the Asia‐Pacific region and examines its determinants over the period 1980–2014. The study analyses capital deepening, human capital, technology, share of agriculture in GDP, financial development, institutional quality, inflation as well as macroeconomic variables as potential determinants of productivity, and identifies the differences in the impact of these factors on the productivity of developing and developed countries. Using panel cointegration and group‐mean fully modified ordinary least squares estimation, the study finds that capital deepening, human capital, technology, institutional quality and macroeconomic variables (i.e. government size and openness) are significant determinants of labour productivity of both developing and developed economies of the Asia‐Pacific region. The study further finds that while both trade openness and foreign direct investment affect productivity of developing economies positively, only trade openness has a positive and significant impact on the productivity of developed economies. The share of agriculture in GDP affects the labour productivity of developing Asia‐Pacific economies significantly but not that of developed economies. Furthermore, capital deepening has a much higher impact on the productivity of developing Asia‐Pacific economies than that of developed economies.     

Foreign Direct Investment and Enterprise Restructuring in Central Europe

Foreign direct investment is at the forefront of economic policy decisions in Central Europe, as it is expected to accelerate enterprise restructuring and aid in the successful transition to a market economy. This paper contains a panel data study of the effects of FDI in 11 different manufacturing sectors within three Central European economies: Hungary, Poland and the Czech Republic. We find evidence that FDI has increased labour productivity levels in most manufacturing sectors. We are able to differentiate between sectors with a high elasticity of substitution between labour and capital and those that are inelastic. We have also presented evidence to support the theory that the impact on labour productivity is predominantly due to the intangible assets introduced by foreign firms, rather than simply the fixed capital investment associated with FDI.     

Real wages,inflation and labour productivity in Australia

This article presents an analysis of real wages, inflation and labour productivity interrelationships using cointegration, Granger causality and, most importantly, structural change tests. Applications of tests to Australian data over the 1965 to 2007 period corroborate the presence of a structural break in 1985 and show that a 1% increase in manufacturing sector real wages led to an increase in manufacturing sector productivity of between 0.5% and 0.8%. Comparable estimates for the effect of inflation on manufacturing sector productivity have limited statistical significance. Granger causality test results suggest that real wages and inflation both Granger cause productivity in the long run.
