OUTPUT,PRODUCTIVITY AND WAGES IN THE BRITISH COAL INDUSTRY BEFORE 1914: A MODEL WITH EVIDENCE FROM THE DURHAM REGION*

This paper proposes a model of productivity and wages in the Durham coal industry during 1882–1914. The model predicts a negative relationship between wages and productivity which derives from the industrys production function and wage-setting arrange- ments and does not require or imply a ‘leisure preference’ by miners. It is also suggested that predicted effects of some variables on productivity are different from those proposed by previous investigators. Using modern time-series methods on data for output per worker and per shift, it is shown that the two measures essentially reflect predicted effects on output and productivity respectively.     

Money,Investment and Consumption: Keynes's Macroeconomics Rethought

The dominant supply-side foundation for explanations of the growth potential of an economy is losing its persuasive power in the face of persistent losses in output and employment experienced by mature economies in the aftermath of the financial crisis. There is now an opening for eclectic approaches that consider the interaction between supply-side and demand-side factors in shaping macroeconomic outcomes. In this paper, we develop a model that reflects such an approach to interpreting differential productivity growth over the long run, and then present empirical results for several countries. On the supply-side, the model considers the linkage between the intensity and efficacy of the accumulation process and the gains of productivity in terms of a Kaldorian Technical Progress Function. Then, drawing on the Evsey Domar's Keynesian notion of dynamic equilibrium as the growth rate that reconciles additions to capacity with the absorption of aggregate output by demand, we derive a locus for a ‘Domar equilibrium path’. Imbalances caused by excess aggregate supply or demand, and by the effects of ‘shocks’ are presented and discussed using a simple graphical framework. In the empirical analysis, an error-correction model is applied to the fundamental relationship between the rate of growth of product per work-hour and the rate of capital accumulation. The results suggest that the differences in productivity growth among countries are can be explained in terms of the efficiency of their ‘accumulation paths’.     

LISREL growth model on direct and indirect effects using cross-country data

Many papers have analyzed the factors affecting economic growth. However, these have concentrated on direct effects and ignored indirect effects through other variables in the model. This study investigates direct and indirect effects of various factors on growth with a causal growth model using LISREL (LInear Structural RELations) for a sample of 105 countries over the period of 1975–2002. Results suggest that ignoring the indirect effects of productivity growth, geography and economic development on economic growth may lead to a considerable underestimation of their ‘true’ total effects on growth. While the importance of the indirect effects of productivity growth and geography relative to their direct effects changes with the estimated model, the relative importance of the indirect effect of economic development on growth is found to be robust to different model specifications.     

Intertemporal consumer behaviour in developing countries

This paper explores aggregate consumption behaviour in four developing countries under the assumption that consumers' planning horizons do not extend over their expected lifetime. Under certain conditions, the resulting ‘moving planning horizon model’ suggests that changes in current income would exert considerably more influence over current consumer spending than is predicted by forward-looking theories of consumption which typically assume that consumers' planning horizons coincide with expected lifetime. Estimation of the model for the group of developing countries provides empirical support for the role of changes in current income in influencing the consumption process. The results also reveal that consumers are relatively short-sighted sinced the length of the planning period of consumers ranges from just over ten months. An important implication of these findings is that policy measures can be effective not only if they influence consumers' permanent incomes but also if they affect changes in current income.     

Multinational production,exports and aggregate productivity

This paper presents and estimates a dynamic model of multinational production (MP) and exports with heterogeneous firms. The model highlights the interaction between firms' location and export decisions and their effect on aggregate productivity. The model is structurally estimated using firm-level Indonesian manufacturing data. The results are broadly consistent with the pattern of productivity, exports and MP across firms. Counterfactual experiments suggest that there are substantial productivity gains due to international trade and MP. The implied changes in steady state real wages, however, are relatively small. The experiments emphasize that the nature of firm-level trade and MP interactions are crucial to determining the aggregate effects of trade and foreign direct investment policy.     

Is there an export or import-led productivity growth in rapidly developing Asian countries? a multivariate VAR analysis

In contrast to cross-country studies, the paper investigates the relationships between trade and labour productivity for nine rapidly developing Asian countries in a time-series framework using a vector error-correction model. Independent tests on the long-run and short-run relationship between trade variables of exports and imports and productivity are conducted. The results suggest that trade has an important impact on productivity and output growth in the economy, however it is imports that provide the important?‘virtuous’?link between trade and output growth. The results indicate that exports and imports have qualitatively different impacts on labour productivity. The long-run result shows that there is no causal effect from exports to labour productivity growth for Hong Kong, Indonesia, Japan, Taiwan and Thailand; thereby suggesting that there is no export-led productivity growth in these countries. However, significant causal effects were found from imports to productivity growth, suggesting import-led productivity growth in India, Indonesia, Malaysia, Philippines, Singapore and Taiwan. In addition, the results indicate that imports tend to have greater positive impact on productivity growth in the long run.     

Joan Robinson as a teacher

Sraffa's construct, the standard commodity, responds to Ricardo's search for an ‘invariable’ measure of value, since it is a measurement unit invariant to changes in distribution. But Sraffa suggests that there is no ‘counterpart,’ no analogous search or needed construct, for the ‘problem’ of ‘difference’ as distinct from change (‘why two commodities produced by the same quantities of labour are not of the same exchangeable value’). Difference in this sense is crucial to Marx, who distinguishes value and surplus-value from capitalist price and profit in part in order to theorize differences as systematic value transfers. In that effort, Marx repeatedly poses commodities and capitals as ‘aliquot parts’ of the whole, so that profit is a redistributed share of aggregate surplus-value. This paper shows that, when Marx's aliquot part imagery is formalized, the resulting hypothetical system represents a meaningful ‘counterpart,’ a construct with a function in Marx's analysis of difference comparable to that of Sraffa's standard commodity in analyzing distributional change. A Marxian ‘standard system’ posing each commodity as an aliquot part of the social capital (a) defines the needed labor-time unit of social account by homogenizing heterogeneous concrete labors as socially average (‘abstract’) labor while simultaneously (b) allowing the derivation of exchange-value (e.g., capitalist production price) on that scale via summation of directly and indirectly embodied labor. Indeed, Marx's approach to production prices as resulting from an inter-industry redistribution of aggregate surplus-value is shown to be algebraically identical to the calculation of labor-embodied under ‘aliquot part’ production conditions.     

A Case for Managed Exchange Rates*

The incorporation of adaptive expectations by Dornbusch in a Mundell-Fleming model modifies significantly the traditional results of policy effectiveness in a small, open economy. While monetary policy is still able to influence aggregate demand when flexible exchange rates prevail, the effects of this policy on other important variables in the economy during the adjustment process to a new equilibrium may be considered sufficiently ‘disruptive’ so that the authorities will be hesitant to use their only fully-effective policy instrument for income-stabilization purposes. However, by adding a target level for the exchange rate to their list of goal variables and by using an appropriate mix of monetary and fiscal policies, it appears to be possible for the government to avoid these disruptive side effects.     

Asymmetric output growth effects of government spending: Cross-sectional and panel data evidence

Using a model that accommodates asymmetric adjustments of output growth to changes in growth of government spending, the effects of aggregate and disaggregate government spending variables on output growth are examined. Both cross-section and panel regression estimations are conducted. Robustness of results to joint-endogeneity of output and government spending, alternative conditioning variables, and cointegration is investigated. Aggregate government spending appears to have positive output growth effects particularly in periods of below-trend growth in this variable. The government sector's productivity appears to be higher than non-government sector's productivity when spending growth is below-trend growth and only for non-OECD countries; no differences in sectoral productivities are detected for OECD countries. Government consumption spending has no significant output growth effects, but government investment spending has positive output growth effects particularly when its growth falls below its trend-growth; this favorable effect turns negative when government investment spending growth exceeds its trend-growth. Results are robust across alternative model specifications and estimation methods.     

Products and Productivity*

When firms make decisions about which product to manufacture at a more disaggregated level than observed in the data, measured firm productivity reflects both characteristics of the firm and attributes of the products that are non‐randomly chosen by the firm. This paper develops a model of industry equilibrium in which firms endogenously sort across products and characterizes the resulting bias in measured firm and aggregate productivity. Calibrating the model's parameters, we show that endogenous product selection can have quantitatively important effects on measured firm and aggregate productivity and their response to changes in parameter values.     

Catch-up and convergence: a model of cumulative growth

This article builds a model of cumulative growth in order to explain the patterns of convergence and divergence in levels of productivity for a large sample of developed and developing countries. Determinants of productivity growth are endogenized: investment equipment share in GDP, innovative activity and the level of schooling. The catch-up hypothesis states that lagging countries should enjoy a higher rate of productivity increase. In fact, this hypothesis must be qualified, countries that possess a ‘social capability’ can catch up to the technological leaders. The model presented here tries to take account of some important determinants of the social capability. The growth of productivity rests on a cumulative growth mechanism based on investment, innovation and education. The model is estimated for a sample of 59 countries over the period 1960–85. Contrary to most recent studies on the subject, a general pattern of divergence rather than convergence in productivity levels is found.     

A Note on Aggregate Investment in Australia*

The purpose of this paper is to explore the relevance of Tobin's ‘q theory’ of investment in explaining aggregate investment in Australia, over the period from December 1966 to December 1986. Using standard capital stock data, the q theory performs poorly. However, the cost of adjustment model implies that the conventional capital stock data need to be revised to allow for these adjustment costs. Once this is done, it is found that the q theory explains a statistically significant (although small) proportion of the movements in aggregate investment The residual behaviour of investment is well explained by an accelerator model     

Trade and technological explanations for changes in sectoral labour demand in OECD economies

This paper sets out to establish the main determinants of variations in the demand for aggregate labour in manufacturing and service sectors (22) for a cross-section of OECD countries (14). A relatively new panel data set is employed in the analysis, the OECD's International Sectoral Data Base. Preliminary analysis revealed that the ‘within’ sector variation in the wage share dominated overall variation for most countries and time periods. A separate dynamic model was thus generated to explain the ‘within’ sector variation in the wage share. This model contained real wages, output, the capital stock, technological change (total factor productivity) and trade (the imports to value-added ratio) as independent variables. In addition the wage level was also interacted with these explanatory variables on the presumption that skill is positively correlated with the level of wages. Because of the potential for simultaneity bias, estimation was conducted by IV and OLS. The main findings were that the capital stock and technological change were the main determinants of shifts in labour demand. While some countries reported the trade variable as significant its influence was only of slight importance in most cases. The interaction terms proved to be significant in a large number of countries. Some evidence was found that capital and technological were complementary with skill. Overall it was found that broad agreement existed across countries in the factors which influence labour demand despite considerable differences in the cross-country nature of labour market institutions.     

Firm-level productivity in Latin America and the Caribbean

While the accumulation of factors of production, both physical and human capital, has helped Latin America and the Caribbean (LAC) to narrow the income gap with developed economies, aggregate productivity is still relatively low. Although there are numerous determinants of aggregate productivity, it is largely based on the underlying productivity of all firms in the economy. Using firm-level data from several waves of the World Bank Enterprise Survey and Chile's National Manufacturing Survey, we explore the ‘what’ question on productivity dispersion in LAC. We document three stylized facts: (i) there are significant differences in firm productivity within industries – the firm at the 90th percentile of the productivity distribution produces almost seven times as much output (using the same measured inputs) as the 10^th percentile firm; (ii) productivity differences persist over time – regressing a firm's current productivity on its one-year lagged productivity yields an autoregressive coefficient of around 0.9; and (iii) most of the growth in aggregate productivity comes from improvements in the productivity of existing firms.     

KEEPING UP WITH THE JONESES, GROWTH, AND DISTRIBUTION

A recent class of models on ‘keeping up with the Joneses’ suggests that comparison with the consumption of other individuals affects individual utility. This paper nests three variants of the ‘Joneses’ effect into an otherwise standard growth model. Under some conditions, growth and distribution are jointly determined, presenting thus a unification of the relevant theories. These variants are however not equivalent in terms of their effects on growth and distribution. It is also shown that, at least if comparisons‐in‐mean predominate, rises in the mean skills level and in the exogenous skills variance increase both growth and inequality with ambiguous effects on aggregate welfare.     

The specificity of manufacturing in Marx's economic thought

Abstract

This article examines Marx's approach to manufacturing and the extent to which manufacturing could be considered to have a special place in Marx's economic thought, especially in relation to accumulation and growth. The important ‘progressive’ features of manufacturing that can be found in Marx's writings and which are discussed here include: division of labour; socialisation of labour; mechanisation; increasing returns to scale; learning-by-doing; technological advancement; and overall, superior potential for cumulative productivity increases. These insights anticipate some of the thinking around the specificity of manufacturing found in twentieth-century structuralist development economics and some heterodox schools of thought such as Kaldorian approaches. This article suggests an interpretation of Marx as having a two-dimensional conceptualisation of activity specificity, with not only sectoral but also ‘technological–organisational’ dimensions, where these two dimensions are not fully independent of each other.     

Productivity growth patterns in US dairy products manufacturing plants

We analyse the productivity growth patterns in the US dairy products industry using the Census Bureau's plant-level data set. We decompose Total Factor Productivity (TFP) growth into the scale and technical change components and analyse variability of plants’ productivity by constructing transition matrices. We observe a cross-sectional dispersion in plant-level productivity growth in the industry. Even though the industry aggregate shows a small TFP growth rate ?0.3%, quartile rank analysis shows that while the lowest productivity quartile plants average 1.9% loss in productivity, the highest productivity quartile plants average 1.1% growth annually. Our results show considerable movements of plants in their productivity rank categories overall and across age groups, and we find that the scale effect contribution to TFP growth accounts for about 90% of TFP growth on average in the industry. These plants extract scale efficiencies over technological progress to fuel TFP growth. The youngest plants start with the lowest productivity growth at the initial time period, but they catch up older plants productivity, which present the highest average growth rate through years. This may indicate a ‘learning-by-doing’ process for the industry.     

Did the rising importance of services decelerate overall productivity improvement of Turkey during 2002–2007?

This paper answers the question of what would have been the growth rate of aggregate productivity in Turkey between 2002 and 2007, had it realized China’s rates of productivity growth in agriculture, industry, and services. It does this in a three-sector general equilibrium model calibrated to the Turkish economy over the 2002–2007 period. The main findings are: (i) Turkey would have had much higher aggregate productivity growth over this period if it had experienced China’s service sector productivity growth; (ii) very low productivity growth rates in finance and in the non-market service sector are the main culprits behind Turkey’s weak service-sector performance.     

The Short Period and the Long Period in Macroeconomics: An Awkward Distinction

The aim of this paper is to show that the meaning of the well-known concepts of short period and long period is often unclear and may be seriously misleading when applied to macroeconomic analysis. Evidence of this confusion emerges through reappraisal of the interpretative debate of the 1980s and 1990s, which aimed to establish whether Keynes's General Theory should be considered a short- or long-period analysis of the aggregate level of production. Further evidence is provided by the ambiguous use that seems to be made of this distinction in macroeconomics textbooks, as will be shown in the paper. Having explored some possible explanations for the difficulties in defining and applying these methodological tools at a ‘macro’ level, the conclusion is drawn that it would be preferable to abandon this terminology in classifying different aggregate models and simply to make explicit the given factors and the independent and dependent variables in each model, exactly as Keynes did in Chapter 18 of his major work.     

Convergence in Productivity Across Industries: Some Results for New Zealand and Australia

New Zealand shares a wealth of common interests and experiences with Australia. This has tempted some to assume that these economies form an ‘Economic Club’, in which one would expect to identify common aggregate trends and growth experiences. In this paper we present results that test, and generally reject, convergence in labour productivity across Australia and New Zealand, using both aggregate and disaggregate, industry‐level data. We find that only two industries satisfy our definition of Conditional Convergence (Agriculture, Forestry and Fishing and Cultural and Recreational Services), and that the Mining and Wholesale Trade industries have particularly important roles to play in explaining the measured divergence. Cointegration‐based tests reveal more stochastic trends governing Australian productivity than in New Zealand. The evidence suggests, therefore, that the underlying growth processes of the two economies are fundamentally different, thereby questioning the relevance of aggregate comparisons between them. New evidence using industry‐level data does not, therefore, resolve the aggregate‐level ‘non‐convergence puzzle’ identified here, and elsewhere.
