Dynamics of Trade Integration and Technological Convergence

The issue of the impact of trade on economic performance and labour markets has been intensively discussed in recent literature on trade liberalization and globalization, where the debate was mainly about identifying the relative impact of trade and technology. The bulk of the existing literature in this area employs, almost without exception, a static Heckscher-Ohlin framework that seems not to be a suitable tool for analysing the ongoing dynamics. This paper presents a dynamic multi-sectoral framework with heterogenous labour to explore the issue of trade liberalization and sectoral catching-up in productivity levels. The model is basically an input-output framework with Schumpeterian features; the latter are modelled as the impact of transitory rents that result from uneven productivity growth and technological catching-up upon the price and quantity systems of the trading economies. Relative productivity and wage rate dynamics across sectors determine the comparative costs and the dynamics of trade specialization. In the Appendix, the equilibrium solutions of the model are derived.     

Exploring the financial consequences of the servitization of manufacturing

Commentators suggest that to survive in developed economies manufacturing firms have to move up the value chain, innovating and creating ever more sophisticated products and services, so they do not have to compete on the basis of cost. While this strategy is proving increasingly popular with policy makers and academics there is limited empirical evidence to explore the extent to which it is being adopted in practice. And if so, what the impact of this servitization of manufacturing might be. This paper seeks to fill a gap in the literature by presenting empirical evidence on the range and extent of servitization. Data are drawn from the OSIRIS database on 10,028 firms incorporated in 25 different countries. The paper presents an analysis of these data which suggests that: [i] manufacturing firms in developed economies are adopting a range of servitization strategies—12 separate approaches to servitization are identified; [ii] these 12 categories can be used to extend the traditional three options for servitization—product oriented Product–Service Systems, use oriented Product–Service Systems and result oriented Product–Service Systems, by adding two new categories “integration oriented Product–Service Systems” and “service oriented Product–Service Systems”; [iii] while the manufacturing firms that have servitized are larger than traditional manufacturing firms in terms of sales revenues, at the aggregate level they also generate lower profits as a % of sales; [iv] these findings are moderated by firm size (measured in terms of numbers of employees). In smaller firms servitization appears to pay off while in larger firms it proves more problematic; and [v] there are some hidden risks associated with servitization—the sample contains a greater proportion of bankrupt servitized firms than would be expected.

Industrial Effects of European Community Integration

This paper examines the potential effects of European Community (EC) integration. It develops a number of assumptions representing the EC directives, and introduces them in the INFORUM system of models, which links inter-industry dynamic macro-economic models of 10 countries. These assumptions include the deregulation of financial services, abolition of border controls, increased competition, economies of scale and opening up of government procurement. According to the system results, the European economies will experience higher economic growth and higher per capita income, with lower prices and higher labor productivity. It is expected that the rest of the world economies will not be affected significantly by the European integration. Finally, the integration process will generate diverse results across sectors in different countries.

Outsourcing of Services and the Productivity Recovery in U.S. Manufacturing in the 1980s and 1990s

Manufacturing productivity growth recovered during the 1980s and 1990s, while other sectors, particularly services, did not. In the same period U.S. manufacturing has engaged in the “outsourcing” or “contracting-out” of service functions. Has the recovery of manufacturing been accomplished by industrial reorganization--sloughing off sluggish services--rather than technical progress? We analyze this question by reducing service inputs to their consituent elements of material inputs. Service productivity growth is thus imputed to the goods sectors, reducing the recovery of manufacturing productivity growth in the 1980s by one fifth. The recovery lasted through the 1990s, when high productivity performers in manufacturing have been relatively successful at outsourcing sluggishservices.

     

General Equilibrium Analysis of International TFP Growth Rates

The paper presents a study of the total factor productivity (TFP) performance among developed countries between 1985 and 1990. The analysis includes the three large economies: the US, Japan and Europe. A general equilibrium model of these economies is used to estimate TFP growth at the sectoral and at the aggregate levels. The model is based on the fundamentals of the economies and employs only data on input-output flows, factor inputs across sectors, consumption and trade patterns and endowments. Prices are endogenous in the model. They are obtained as shadow prices from the model's linear program and then used to measure TFP growth and decompose it in a technical change effect, a demand effect and a terms-of-trade effect. The technical change effect is highly correlated with the conventional Solow residual measure. This result lends support to the standard measure of technological change.     

Public policies and convergence

This paper employs a dynamic framework to compare the effects of alternative government policies on convergence of industrialized economies to the technology frontier. The government's instruments include facilitating private investment and education policy. The latter enhances skills of heterogenous specialists and implies the decision on their respective shares. The analysis distinguishes between an isolated policy of a single economy and coordinated policies of various countries. Which policy maximizes the speed of convergence is crucially affected by the economy's state of development. A policy switch between the mentioned instruments while catching-up may be preferable.     

Servitization: Disentangling the impact of service business model innovation on manufacturing firm performance

As manufacturing businesses operate in an ever more competitive, global economy where products are easily commoditized, innovating by adding services to the core product offering has become a popular strategy. Contrary to the economic benefits expected, recent findings pinpoint implementation hurdles that lead to a potential performance decline, the so-called ‘servitization paradox’. In this paper, we analyze this paradox by disentangling the value creation and value appropriation processes of 44 national subsidiaries of a global manufacturing firm turned product-service provider, in the 2001–2007 period. Our findings show that the firm under study is able to successfully transcend the inherent substitution of products by services and to enact complementary sales dynamics between the two activities. Moreover, labor-intensive services such as maintenance, which imply higher levels of customer proximity, further enhance product sales. Empirical results also reveal a positive yet non-linear relationship between the scale of service activities and profitability: while initial levels of servicing result in a steep increase in profitability, a period of relative decline is observed before the positive relationship between the scale of services and profitability re-emerges. These findings suggest the presence of initial short-term gains but also indicate the existence of a ‘profitability’ hurdle; profitable growth seems feasible only to the extent that investments in service capability are translated into economies of scale. In helping to clarify the performance implications of service innovation, our findings suggest pathways to sustainable growth through servitization for manufacturing firms.     

Post-War Growth, Productivity Convergence and Reconstruction

In this paper, it is shown that aggregate cross-country analyses of the growth process of the industrial countries should take reconstruction effects into account. The enormous growth rates in many European countries and in Japan in the fifties which often appear as outliers in aggregate analyses of productivity convergence can be understood as a catching-up with respect to the past. Neoclassical capital deepening combined with arguments from growth models relying on the stock of knowledge, knowledge spillovers and technological diffusion as the source of economic growth can explain the fast reconstruction after the war, without referring to country-specific growth factors.

Market Imperfection and Productivity Growth—Alternative Estimates for Taiwan

This study first explores why the shares of factor inputs have not been measured correctly and concludes that the earlier findings are biased due to the miscalculation of factor shares which have produced low estimated total factor productivity (TFP) growth in the East Asian countries. Second, three approaches are proposed to empirically illustrate the impact of capital and labor shares on the estimates of TFP growth. It is suggested that TFP growth in the East Asian economies will be understated if net indirect taxes and imperfect competition profit are ignored. Finally, by taking the net indirect taxes and imperfect competition profits into account, the result of this paper indicates that Taiwan's economy has enjoyed an average annual TFP growth rate of 3.6% over the period 1980–1999.     

The impact of R&D on factor-augmenting technical change – an empirical assessment at the sector level*

The aim of the paper is to quantify endogenous factor-augmenting technical change driven by R&D investments in a panel of 11 OECD countries over 1987–2007. This paper contributes to the scant empirical evidence on the speed, sources and direction of technical change for various sectors and production factors. Assuming cost-minimization behavior, a CES framework is used to derive a system of equations that is estimated by a GMM system estimator. The estimated factor-augmenting technology parameters show that in most sectors, technical change was labor-augmenting and labor-saving. Statistically significant effects of manufacturing and services R&D were found on factor-augmenting technical change (with the highest R&D elasticities found in the high-tech manufacturing and transport, storage and communication sectors). Whereas ‘in-house’ R&D stimulates total factor productivity, R&D spilled over to other sectors has a capital-augmenting effect accompanied by a higher use of labor. The results of this study provide a starting point for incorporating endogenous factor-augmenting technical change in impact assessment models aimed at broad policy analysis including economic growth, food security or climate change.     

FORMAL AND INFORMAL SECTORS IN CHINA AND INDIA

This paper discusses the estimation of a social accounting matrix that distinguishes between formal and informal activities for China and India for 2000 and 1998–99 respectively. Wage shares for formal/informal employment in China and net domestic product shares for organized/unorganized sectors in India are used as weights to calculate the size of the two sectors. The proposed methodology is a first step towards an integrated approach to account for the dualism of many economies in the developing world. The results can serve as data input for any policy-driven CGE model for developing countries.     

Should everybody be in services? The effect of servitization on manufacturing firm performance

The servitization of the manufacturing sector refers to the evolution of manufacturers' capabilities to offer services as complements to or substitutes for the goods that they produce. A vast literature has described these strategies and has shown that this phenomenon is widespread and growing in most developed economies. However, very little systematic evidence of the extent or consequences of servitization based on a comprehensive data set of firms exists. In this paper, we provide such evidence using exhaustive data for French manufacturing firms between 1997 and 2007. We find that the vast majority of French manufacturers sell services in addition to producing goods. The shift toward services is growing steadily but at a slow pace. We also estimate the impact of servitization on firm performance. Controlling for various sources of endogeneity bias, our most conservative results show that firms that start selling services increase their profitability by 0.4%, their employment by 2.1%, and their total sales by 0.6%. For small businesses, we also find a positive impact on the production of goods. We also uncover strong heterogeneity across manufacturing industries.     

Temporary contracts and labour productivity in Spain: a sectoral analysis

This paper analyses the impact on sectoral labour productivity growth caused by the increase in the use of temporary employment contracts in Spain over the period 1987–2000. With this aim, we estimate a production function model in which effective labour is represented by the shares of permanent, temporary and self-employed workers. Results suggest that productivity growth has been slowed down by the use of temporary contracts for regular jobs and that this has not been affected by compositional changes in activity over the period. However, this effect has only been detected in the manufacturing and energy sector, in contrast to low-technology low-human capital sectors like construction and hospitality.     

Productivity and Inflation: a Paradox

In his Budget speech, Mr. Lawson drew attention to the greatly improved record of productivity growth in UK manufacturing:
"During the 1960s, and again in the 1970s, growth in manufacturing productivity in the UK was the lowest of all the seven major industrial countries in the world. During the 1980s, our annual rate of growth of output per head in manufacturing has been the highest of all the seven major industrial countries."
Ironically this success in regard to productivity may cause a problem in regard to inflation if the UK moves to a fixed exchange rate policy within the EMS. In this Viewpoint we report the consequence of such a move and also describe the possible required rise in the exchange rate if price stability is to be attained. We show that price stability requires the exchange rate to rise (i) to offset world inflation and (ii) to compensate for the productivity gap between the traded and non-traded sectors.     

PRODUCTIVITY AND STRUCTURAL CHANGE: A REVIEW OF THE LITERATURE

Abstract.  This paper is a survey of the existing research on structural change at various levels of aggregation with a special focus on the relation to productivity and technological change. The exposition covers the research concerning the development of the three main sectors of the private economy, multisector growth models and recent evolutionary theories of structural change. Empirical studies of the reallocation of market or sector shares as a result of differential productivity developments are also discussed. The synthesis emphasizes the crucial interaction of supply- and demand-side forces in shaping structural change.     

Disaggregate productivity comparisons: sectoral convergence in OECD countries

International comparisons of productivity have used exchange rates or purchasing power parity (PPP) to make output comparable across countries. While aggregate PPP holds well in the long run, sectoral deviations are persistent. It raises the need for a currency conversion factor at the same level of aggregation as the output that is compared. Mapping prices from household expenditure surveys into the industrial classification of sectors and adjusting for taxes and international trade, I obtain an expenditure-based sector-specific PPP. Using detailed price data for up to 8 years between 1970 and 1999, I test whether the sectoral PPPs adequately capture differential changes in relative prices between countries. They work well for agriculture and the majority of industrial sectors, but not for most service sectors and for manufacturing sectors that produce differentiated products. Using the most appropriate conversion factor for each industry, productivity convergence is found to be taking place in all but a few industries for a group of 14 OECD countries. The latter results are robust to the base year used for the currency conversion.     

Localized Innovation and Productivity Growth in Asia: An Intertemporal DEA Approach

Recent contributions to growth theory stress the importance of localized innovation for the performance of more backward countries. In earlier papers, analyses by means of DEA techniques confirmed this intuition. In this paper, we extend this type of analysis by relaxing the macroeconomic viewpoint adopted until now. New databases on output, labor and capital input in the agricultural and manufacturing sectors are developed for 40 countries. Using intertemporal DEA, it is found that changes in the global production frontier are localized at high levels of capital intensity. This result is stronger in agriculture than in manufacturing. Further, a decomposition of labor productivity growth in eight Asian countries for the period 1975–1992 into the effects of capital intensification, learning and innovation is made. The results suggest that there is a particular development path in which increases in capital intensity appear to be a prerequisite to benefit from international technology spillovers.JEL Classification: O14, O30, O40, O47     

Absorptive Capacity and Productivity Spillovers from FDI: A Threshold Regression Analysis*

This paper explores whether the effect of foreign direct investment (FDI) on productivity growth is dependent on absorptive capacity using recently developed threshold regression techniques. In manufacturing sectors where technology‐exploiting multinationals are prevalent, the results point to the presence of nonlinear threshold effects: the productivity benefit from FDI increases with absorptive capacity until some threshold level beyond which it becomes less pronounced. But there is also a minimum absorptive capacity threshold level below which productivity spillovers from FDI are negligible or even negative. On the contrary, no evidence of productivity spillovers is found in sectors where FDI appears to be motivated by technology‐sourcing considerations.
