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.     

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.     

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.     

Exports,Supply Constraints and Growth: An Investigation using Regional Data

In this work we first model the role of demand‐ and supply‐side factors (labour market adjustment, productive efficiency) in explaining economic growth. Empirically testing the model, we evaluate why different growth regimes may appear in the 20 Italian administrative regions. This exercise uses a two‐stage econometric approach. Estimates for the elasticity of manufacturing output to exports are obtained from regional time series: a significant long‐run relationship indicates the existence of a demand‐constrained growth regime. We then ascertain whether the regional dispersion of supply‐side factors has an impact on the regional dispersion of growth regimes. The empirical evidence supports our expectations of strong regional differences. Southern regions are less likely to display demand‐constrained regimes. In explanation of these differences, second‐stage analysis reveals that a strong role is played by such efficiency‐enhancing factors as technological innovation, bank diffusion and ‘social capital’. No role is found for labour market rigidities.     

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.     

Trade policy and industrial development: iron and steel in a small open economy, 1870−1913

In this paper we argue that effective tariff protection associated with the 1879 National Policy and the 1887 Tupper tariffs triggered investment in new, technologically advanced blast furnaces that were capable of accommodating rapid output expansion. This conclusion is based on an appreciation of the timing of late nineteenth‐century investments in Canada and their connection to changes in government policy and other demand determinants. In our empirical investigation we use new information on westbound transatlantic freight rates, intra‐continental transport costs, and furnace‐specific micro‐data, and we acknowledge the endogenous relationships linking investment to domestic demand, labour costs, and tariffs.     

The trade-off between real wages and employment in an open economy (Belgium)

The purpose of this paper is twofold. First, we discuss the nature and quantitative order of magnitude of the trade-off between real wages and employment in the small open economy Belgium. Second, we draw policy conclusions from our positive analysis, and compare income policies with alternative approaches to employment stimulation (including shorter working hours and currency depreciation).To study the trade-off between real wages and employment, we treat external balance as a binding constraint on demand management. An exogenous increase in real wages, affecting adversely the competitiveness of domestic producers on the export and import markets, impairs external balance. The impact of the wage increase on output and employment is evaluated through the reduction in domestic demand required to restore external balance.At the empirical level, we endeavour to evaluate separately the influence on exports and imports of domestic costs at unchanged capacity levels, and of capacity levels themselves. And we endeavour to evaluate the influence of real wages on capacity levels through scrapping and investment. All evaluations rely on the foreign trade equations of econometric models of the Belgian economy.The conclusions from our empirical investigation are first that estimates of the trade-off between real wages and employment in Belgium are subject to considerable imprecision; second that the short-run elasticity of employment with respect to real wages keeping capacity constant is probably quite small (like -0.2), and definitely less than unity in absolute value; third that the corresponding medium-run elasticity taking into account capacity adjustments is probably sizeable (like -2), and definitely larger than unity in absolute value; and fourth that exchange rate adjustments might not make too much difference, in either the short run or the medium run.Turning to a discussion of policy, we shall argue that these conclusions give support to a policy of constant real labour incomes, of comprehensive efforts to redistribute work through shorter working hours or related schemes, and of selective efforts to slow down capacity scrapping.     

Structural Changes in Australian Manufacturing Industry*

The paper uses a neoclassical production function and historical data to test for structural stability in Australian manufacturing industry. The production function is an extended constant elasticity of substitution form in which factor substitution elasticity, returns to scale and market structure in output, capital and labour are testable hypotheses. Tests for structural changes in homogeneity and factor substitution elasticity relations are based on overall and individual tests of covariance analysis and also on a special version of the Swerling-Kalman filtering systems as proposed by Cooley and Prescott. The empirical findings possess desirable statistical properties and indicate the existence of structural instability in the industry. The evidence also repudiates the assumptions of unitary factor substitution elasticity, constant returns to scale and market competitiveness in output and factors of production.     

The Elasticity of Demand for Labour in Australia

The elasticity of demand for labour at the aggregate level is an important parameter for macroeconomic analysis. In particular, policy issues concerning the impact of wage falls on employment and unemployment hinge on the size of this parameter. It is argued in the present paper that previous work on the elasticity of demand for labour in Australia has been unsatisfactory in a number of ways. A new set of estimates is provided that are derived using a better methodology than before.     

A note on capacity utilization,productivity, and the Canadian output gap

This study revises estimates of real Canadian potential output and the real GNP gap by applying a method of directly estimating the actual and potential factor utilization rates to quarterly Canadian data. The empirical results indicate that capital utilization varies just under twice as much as labour use over the cycle. The results also suggest that labour productivity will vary procyclically, with the elasticity of productivity with respect to the employment rate estimated to be 1.42.     

Policy reform and labour demand in branches of Sri Lankan manufacturing industry

Many policy reforms in developing countries aim to remove factor market distortions. Whether such reforms reduce unemployment depends partly on the substitution possibilities between labour and other factors of production. This paper examines labour demand in seven branches of Sri Lankan manufacturing industry, using data on 4-digit industrial categories over the 1990 to 1997 period. The Box–Cox transformation is used to allow for flexible, and data-dependent, elasticities. The elasticity of capital–labour substitution varies widely across the branches of industry and is usually variable rather than constant. The average, long-run own-wage elasticity of labour demand for the manufacturing sector is estimated as ?0.80, so factor price policy should have an important effect on labour demand in this setting.     

Incorporating International Competitiveness into the Demand for Labour Function: Some Issues of Specification and Interpretation*

This paper attempts to clarify the theoretical status and the empirical role of measures of ‘international competitiveness’ that have been used in econometric demand for labour equations. Some currently popular alternatives are finked to a simple version of the Salter-Swan-Dornbusch (‘Australian‘) dependent economy model which is found to provide insufficient basis for choosing between alternative measures, which in the Australian case at least are found to behave rather differently. In explaining employment in Australia during the period 1971-83, the preferred competitiveness variable is found to play a marginal role only with estimated long-run elasticity similar to that for the real labour cost     

Market power and output stability

The conjectural variation elasticity is used in a comparative statics analysis to show that, contrary to a long-standing tenet of industrial organization, market power may destabilize output when cost and demand are stochastic, under other assumptions similar to those of recent empirical studies.

Supply-side effects of strong energy price hikes in German industry and transportation

This article studies the short-term effects of energy price hikes on the supply of industrial goods and transport services including the repercussions on remuneration of input factors. The empirical analysis is based on a theoretical model, which assumes that the output good is produced by capital, labour and energy according to a nested production function framework where capital and energy are combined by a CES function at the intermediate stage. The output responses to energy price changes are derived, using estimates of the elasticity of substitution. While industry suffered more from the oil price shock of the late 1970s than from that of the early 1970s and the 2004?C2008 upsurge, evidence suggests the reverse for transportation. Regarding the impact on income distribution, both sectors share the same pattern, whereby in the recent episode, rising energy costs were more than compensated by falling unit labour costs, while in the 1970s, cost structures had been strained by an expansive wage policy in addition to the oil price shocks.     

An input-output approach to forecasting gross domestic output and employment intensities by sectors

The purpose of this paper is to integrate two commonly known input-output models of Leontief and Stone for employment analysis. Although assumptions of Leontief model are somewhat different from Stone's model, the empirical analysis can be conducted ignoring the difference between competitive and noncompetitive imports in the initial stage. The Leontief model is used to make predictions of gross domestic output on the basis of predicted imports and final demand by sectors. The predicted output is used to derive employment by sectors for a target year and this in turn is used in Stone's input-output framework for the analysis of total labour intensity by sectors. The approach on the estimates of labour intensity by sectors is illustrated using Japan's input-output data.     

STRATEGIC INVESTMENT IN A LABOUR‐MANAGED DUOPOLY

Developing a Cournot two‐stage game model with strategic capital interaction, we compare two different kinds of equilibrium in a labour‐managed (LM) duopoly. An LM firm's reaction function is negatively sloped when capital and output are simultaneously determined, while the slope of its reaction function in the second stage changes in sign depending on the magnitude of its labour‐expansion elasticity. Hence, whether the LM firms employ more capital and produce greater output at the equilibria in the two‐stage game model than at the equilibria resulting from the simultaneous selection of capital and output depends on the magnitude of their labour‐expansion elasticity.     

A MACROECONOMIC PERSPECTIVE ON SKILL SHORTAGES AND THE SKILL PREMIUM IN NEW ZEALAND*

Qualification and occupation‐based measures of skilled labour are constructed to explain the skill premium – the wage of skilled labour relative to unskilled labour in New Zealand. The data exhibit a more rapid growth in the supply of skilled labour than the skill premium, and a very large increase in the real minimum wage over the period from 1986 to 2005. We estimate the rate of increase in the relative demand for skills and the elasticity of substitution. The data are consistent with skill shortages and a skill‐bias technical change. We examine the effects of the minimum wage, capital complementarity, and the exchange rate on the skill premium. We also test whether the demand for skills and the elasticity of substitution varied across industries and over time.     

Factor Demand in Pakistan's Manufacturing Sector

This paper estimate factor demand function by choosing appropriate technology. Departing from the conventioanl parting from the conventional practice of using and capital as factor inputs we extend the list of factors of production by including energy. Since we have more than two factor inputs the two-level (nested) CES production function is the natural choice for the appropriate technology. Using this technology we derive the factor demand for functions and estimate these for Pakistan's manufactruing sector covering a period from 1959-60 to 1982-83. The output elasticity of labour, capital and energy are found to be 0.47, 0.66 respectively. These informations, in particular, the employment elasticity are extremely important for manpower planning. These findings confirm the capital intensive structure of Pakistan's manufacturing units.

Outsourcing, Imports and Labour Demand

This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.
