The employment elasticity in manufacturing: a rejoinder

The trend in the share of wages is one of the factors affectingemployment elasticity over a specified period of time. Thereare alternative ways of dealing with this trend in a decompositionequation. The method suggested in Mazumdar (2003) might be preferredbecause it yields additional information.     

Trends in employment and the employment elasticity in manufacturing, 1971-92: an international comparison

Employment growth in manufacturing is limited by output growthin this sector, but the elasticity of employment with respectto output has varied widely in different regions and economies.This paper focuses attention on the idea that a major determinantof employment elasticity is the way the fruits of output growthare divided between employment growth and wage growth. But beforewe are able to determine the quantitative dimension of the trade-off,we have to allow for two other factors which affect the sizeof the cake available to labour in real terms. These are: (i)the elasticity of the wage bill with respect to output, whichdetermines the trend in the share of labour; and (ii) the priceeffect, depending partly on the rate of inflation and partlyon the movements of producer prices relative to consumer prices.A simple decomposition procedure is outlined in the paper whichallows us to quantify the relative importance of these factors,and hence give a clearer idea of the labour market outcome leaningto one or other of the two interests, employment growth andreal wage growth. The empirical analysis for different regionsof the world is carried out on time series data for the manufacturingsector collected by UNIDO from the national surveys of membercountries for the decades of the 1970s and the 1980s.     

Organisational change, technology, employment and skills: an empirical study of French manufacturing

This paper analyses the correlations between technological change,organisational change and skill change using a survey on organisationalchange in manufacturing firms conducted in 1993. Considerablediversity is allowed for in terms of the measure of technologicaland organisational change, and the analysis shows a positivecorrelation between technological change and reorganisations,whatever their types. The paper then analyses the relationshipsbetween these changes and the employment behaviour of firms.It shows that changes in the required skills and in the occupationalstructure of firms are more closely connected to organisationalthan to technological change. Although organisational changeaffects the work content and skill requirements of blue collarworkers, it is mainly indirect workers that are affected interms of the number employed. Finally, the analysis shows thattechnology tends to stabilise the workforce whereas the movetowards the model of ‘flexible enterprise’ favoursits renewal.     

Financial development and instability: The role of the labour share

This paper examines the role of the labour share in creating instability in a small open economy. We assume that financial markets are imperfect so that entrepreneurs are credit constrained, and that this constraint is tighter for low levels of financial development. Aghion, Bacchetta and Banerjee [Aghion, P., Bacchetta, P., Banerjee, A., 2004. Financial development and the instability of open economies. Journal of Monetary Economics 51, 1077–1106] have shown that as the degree of financial development increases, output rises but instability appears for intermediate levels of financial development. Crucially, they assume that labour is paid before production takes place, and hence crises are solely due to the increased cost of debt repayment as firms accumulate capital. We show that under the more reasonable assumption that wages are paid at the end of the period, changes in the labour share also play a role in eroding profitability. Our analysis also predicts that financial crises are associated with substantial movements in the sharing of value added between capital and labour.     

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.     

Home country employment and foreign direct investment: evidence from the Italian case

The present paper provides further insights on the relationshipbetween home country employment and foreign direct investment(FDI) undertaken by national firms. The unit of analysis iseach ensemble of firms operating in the same industrial sectorand localised in the same geographical region. That allows usto capture both direct and indirect effects of foreign productionon the parent's environment, which arise through the generationof linkages and externalities. Empirical evidence has been providedwith reference to the Italian case in the decade 1985–95.Results suggest that the impact of outward FDI on the labourintensity of domestic production is negative in the case ofvertical investment undertaken—especially by smaller firms—inless developed countries, and positive for horizontal and market-seekinginvestments in advanced countries.     

The impact of material and service outsourcing on employment in Thailand's manufacturing industries

With increasing emphasis on the importance of outsourcing, the ‘fear of job losses’ has been of significant interest, not only in the developed countries, but also in the developing countries. In this article, we empirically investigate the impacts of intermediate inputs (material) and services outsourcing on the relative demands for skilled and unskilled labour in Thailand's manufacturing sectors from 1999 to 2003. Based on the aggregation of establishment-level data at 4-digit industrial classification, we find that both intermediate inputs and service outsourcing are relatively skill-biased. Further, our results show that intermediate inputs outsourcing has negative impacts on the relative demands for skilled and unskilled workers, whereas service outsourcing shifts the demand towards skilled workers at the expense of unskilled workers.     

The elasticity of substitution in India's manufacturing sector

Using cross-section data and the translog cost function this paper examines the substitution possibilities between capital and materials and labor and materials since raw materials might be used to overcome the bottlenecks caused by shortages of physical capital and skilled labor. Three significant conclusions are: (a) Since materials are substitutable for both capital and labor to a considerable extent, capital and skilled labor may not be a binding constraint on growth. Agricultural materials expansion may substitute for these inputs and lead to expansion in the industrial sector. (b) Fixed proportion models are not warranted in India without modification, and (c) separability tests showed that materials must be included in the production function.     

ICT and employment generation: evidence from Turkish manufacturing

This study is said to be the first attempt in exploring the impact of information and communication technologies (ICT) capital on employment generation/destruction in Turkish manufacturing industry by using labour demand estimation framework. The analysis is based on firm-level data, which includes all firms employing 20 or more employees in Turkish manufacturing for the period 2003–2013. Our findings based on system GMM estimations show that ICT has employment-enhancing effects in Turkish manufacturing. Moreover, our results provide the evidence that tangible ICT capital has stronger employment generation impact than that of intangible ICT capital in medium- and low-tech industries.     

Inter-capital relations and the network organisation: redefining the work and employment nexus

The blurring of organisational boundaries associated with ‘networks’of organisations suggests the need to reconsider how work andemployment are shaped by shifting inter-capital relations. Traditionaltheories of the internalised employment relationship understateits inter-relationship with both the form of inter-capitalistcompetition and the type of inter-capitalist production relations.Also, existing theories of inter-organisational contractingdo not adequately address how these are shaped by employmentrelations, both within and between organisations. An alternativeapproach provides a new perspective for considering forms ofcountervailing power to protect workers' interests in a capitalistsystem continuously shifting from integrated to non-integratedforms.     

The firm-level employment effects of innovations in high-tech US manufacturing industries

We focus on four two-digit manufacturing industries that are known for their high patenting activity. We then use Principal Components Analysis to generate a firm- and year-specific ‘innovativeness’ index by extracting the common variance in a firm’s patenting and R&D expenditure histories. To begin with, we explore the heterogeneity of firms by using semi-parametric quantile regression. We then move on to parametric regressions that include a weighted least squares (WLS) analysis, which explicitly takes into account the different job-creating potential of firms of different sizes. As a result, we investigate the effect of innovation on total number of jobs, whereas previous studies have focused on the effect of innovation on firm behavior. Indeed, previous studies have typically taken the firm as the unit of analysis, implicitly weighting each firm equally according to the principle of ‘one firm equals one observation’. Our results suggest that firm-level innovative activity leads to employment creation that may have been underestimated in previous studies.     

Is labour becoming more or less flexible? Changing dynamic behaviour and asymmetries of labour input in US manufacturing

Have employment and hours become more flexible over time? Vectorauto-regressions are estimated using monthly time-series datato generate impulse responses, which reflect the dynamic responseof employment and average hours of labour input following agiven shock in output demand. A marked change in the US manufacturingsector occurred after 1979. Although there is heterogeneityby industry and asymmetry over the business cycle, hours havebecome somewhat more and employment considerably less flexible,particularly during expansion phases. Employers are apparentlydelaying hiring and relying more on using hours as a bufferto absorb fluctuations in output demand.     

The long-run effects of the real exchange rate on employment and wages in Canadian manufacturing

ABSTRACT

The literature on real exchange rate effects on the labour market is dominated by short-run analysis showing that there is heterogeneity in the responses of firms or industries to a real exchange rate shock. Analysing data on Canadian manufacturing industries, I conclude that there is a common long-run equilibrium across all manufacturing industries controlling for their openness to trade after varying adjustments to a real exchange rate shock have taken place. This conclusion is important from the perspective of policy making because it helps to form expectations about the effects of a real exchange rate movement on the labour market. The results suggest that real appreciation leads to economically significant reductions in employment in manufacturing in the long run. Real wages decrease in industries that are highly engaged in international trade and somewhat increase in industries that are relatively closed to international trade. Both employment and real wages converge quickly to the long-run equilibrium.     

SIDD: An adaptable framework for analysing the distributional implications of policy alternatives where savings and employment decisions matter

The Simulator of Individual Dynamic Decisions, SIDD, is publicly available software for analysing the distributional effects of policy alternatives. SIDD is a framework, rather than a model, in the sense that it is designed to facilitate adaptation to alternative country and policy contexts. The microsimulation framework can generate panel data describing a wide range of characteristics at annual intervals for each adult in an evolving population cross-section. Structural methods are employed to project savings and employment decisions, making SIDD a suitable tool for exploring the incentive effects of policy alternatives, and how these vary across the population and over time. The framework is also a valuable test-bed for empirical analyses of alternative behavioural assumptions, especially those concerning preferences for risk. In an effort to support good policy design and empirical analysis of savings and labour supply behaviour, SIDD has been made free for download from www.simdynamics.org.     

Outsourcing of peripheral services: Evidence from Spanish manufacturing plant-level data

In this paper we empirically explore outsourcing decisions of peripheral services using information from a data set of 926 Spanish manufacturing plants. We find that increases in outsourcing of peripheral services are positively correlated with increases in the plant׳s market share as well as increases in product market competition and product prices. These findings are robust to controlling for whether plants belong to single-plant or multi-plant firms. These patterns are consistent with a strategic shift in the allocation of attention to core manufacturing activities, and are at odds with traditional TCE and PRT theories of vertical integration.     

Heterogeneity and participation in informal employment among non-cultivator workers in India

Labour informality is one of the most serious challenges facing a developing economy like India with large-scale poverty and decent work deficits. This study has inspected possible heterogeneity within informal employment among the non-cultivator workers. Multinomial Logit was applied to find out the determinants of participation in different components of informal employment. Significant heterogeneity within the informal employment on poverty, age, gender, socio-religious communities, educational attainment and industrial classification was observed. There is coexistence of voluntary and involuntary informal employment. Given the diversity of employment, one-size-fits-all policy design may adversely affect sustainable and inclusive growth in India.     

Correcting for biases when estimating production functions: an illusion of the laws of algebra?

This paper shows that the endogeneity bias that allegedly appearswhen estimating production functions using value data, and whichthe literature has tried to deal with since the 1940s, is simplythe result of omitted-variable bias due to a poor approximationto an accounting identity. This problem has no econometric solution.As a result, recent attempts to solve the problem by developingnew estimators are questioned. The only possible way to estimatethe technological parameters of the production function is touse physical quantities.     

Influence of open innovation strategies on employment dynamics: evidence for Spanish manufacturing firms

ABSTRACT

In this paper, we explore the influence of different modes of openness of innovative firms on employment growth. Using a panel database of Spanish manufacturing firms during the period 1998–2015, we analyze the influence open innovation (OI) strategies on employment distinguishing by type of external partner. The main objective of the research is to know whether opening innovation strategy contributes to employment taken into account another firm capabilities and sectorial technological opportunities. For this purpose, a two-step procedure is specified. Firstly, a random-effect computes the effects of OI on the innovation probability. In the second step, the variation of innovativeness due to openness on GMM-system estimation controlling by potential endogeneity and unobserved firm heterogeneity is used. The results support that the influence of open strategy on employment growth is positive. Moreover, the employment depends on the breadth of OI measured by the number of out-inbound relationships. Finally, the employment consequences are different for each mode of open strategy.
