Service Offshoring and Productivity: Evidence from the US

The practice of sourcing service inputs from overseas suppliers has been growing in response to new technologies that have made it possible to trade in some business and computing services that were previously considered non‐tradable. This paper estimates the effects of offshoring on productivity in US manufacturing industries between 1992 and 2000. It finds that service offshoring has a significant positive effect on productivity in the United States, accounting for around 10 per cent of labour productivity growth during this period. Offshoring material inputs also have a positive effect on productivity, but the magnitude is smaller accounting for approximately 5 per cent of productivity growth.     

Jobs and Exposure to International Trade within the Service Sector in Sweden

To establish in which service industries there is international trade (or it may potentially exist), we calculate locational Ginis for different industries. The basic idea is that from this measure of regional concentration of different activities within a country we can identify industries where there appears to be regional trade, and hence also a potential for international trade. Based on our method, we find that: (i) the number of employed in tradable service appears to be at least as large as in the manufacturing sector, (ii) tradable service is much more skill intensive than manufacturing, and (iii) lately, the employment in tradable service has increased substantially. We argue that the last mentioned result is consistent with the substantial growth of skilled labour in Sweden since the mid‐1990s (Rybczynski effect) and factors leading to increased relative demand for skilled labour. Particularly, increased competition from and offshoring to low‐wage countries seem recently to have had a considerable impact on the creation of skilled jobs and the displacement of less skilled jobs in the tradable sector in Sweden. Furthermore, we apply a similar method as for industries to identify tradable occupations. Using our classification of tradable industries and tradable occupations in a Mincer type wage equation, we find that workers in such industries and occupations receive a wage premia of 12–13 per cent.     

The Effects of Globalisation on the US Labour Mark'et: Service Sectors Considered

How has globalisation affected employment and wages in the United States? Existing studies largely ignore the intersector labour movement between the manufacturing and service sectors by focusing only on the intrasector movement within the manufacturing sector. However, by decomposing the aggregate labour demand in the United States, we find that the intersector movement is more substantial than intrasector movement. Motivated by the decomposition results, this study presents a three‐sector model that includes a manufacturing sector and two service sectors at varying skill intensities. The model shows that offshoring might translate into smaller‐than‐expected wage changes because of the intersector labour movement. In line with the theoretical predictions, two notable empirical results are presented. First, an occupation's exposure to offshoring has non‐significant, albeit negative, effects on wages. Second, the more an occupation is exposed to offshoring, the lower its employment in the manufacturing sector as a share of its total employment. Furthermore, these effects are larger for more routine occupations or those requiring less education.     

The Effect of R&D Services Offshoring on Skilled Employment: Firm Evidence

The offshoring of high‐tech services has greatly increased in recent years, with consequences for firms demand for skilled employment in firms. This paper specifically analyses the relationship between R&D offshoring and the demand for R&D employment using firm‐level data for Spanish manufacturing and services companies during the period 2004–11. Estimating different specifications with panel data techniques, we find that this association is statistically positive. In particular, for services firms a 1 percentage point increase in R&D offshoring raises the demand for researchers by about 11 per cent.     

Offshoring and the Skill‐premium: Evidence from Individual Workers’ Data

During the 1980s the United States has experienced an increase in both international trade and the skill‐premium. The association between these two phenomena has proven elusive in the early empirical literature on the subject. Indeed, the consensus among labour economists seems to be that trade has not been the main cause of such increase in the skill‐premium. This view has been challenged by Feenstra and Hanson (1999, Quarterly Journal of Economics, 114, 3, 907) who find that offshoring sizably affects the skill‐premium. I revisit this debate using individual workers’ data from the March Current Population Survey combined with industry‐level trade data. This strategy improves upon the work of Feenstra and Hanson who do not control for the demographic characteristics of the labour force. In my results, offshoring can explain between 9 and 30 per cent of the increase in the college wage premium, relative to high‐school workers. In addition, I find that offshoring can explain 21 per cent of the increase in the relative employment of skilled labour. These results suggest that offshoring may play an important role in the increase in the relative demand of skilled workers.     

Offshoring,Plant Survival and Employment Growth

This paper empirically investigates the effects of offshoring on plant survival and employment growth using data on the Danish manufacturing plants during the period 1995–2006. To control for the potential endogeneity of the offshoring decision, the paper uses instrumental variables and propensity score‐matching approaches. The data allow me to control for the heterogeneity between the units by using firm‐level offshoring activities in different regions and performing the empirical analysis on plantlevel aggregation, which is shown to be of crucial importance. Using firm as a unit of observation, the effect of offshoring is, if any, very small. However, using plant as a unit of observation, there are strong indications that offshoring plays a much larger role for the extensive and intensive margin of adjustments. The results reveal that plants survival prospect is higher if the main offshoring is located in high‐wage countries; lower if it is located in low‐wage countries; and not affected if it is located in medium‐wage countries. Finally, the results also reveal that depending on where the main offshoring is located, the growth rate of low‐skilled employment is 2 to 8 per cent lower in plants of offshoring firms.     

Foreign Direct Investment,Productivity, Demand for Skilled Labour and Wage Inequality: An Analysis of Uruguay

This study seeks to identify the causal effects of foreign ownership on productivity, the demand for skilled labour and wage inequality. With this aim, we use differences‐in‐differences techniques for a panel of Uruguayan manufacturing firms in the period 1997–2005. Our results seem to indicate that FDI causes higher productivity and increased demand for skilled labour. Furthermore, although average wages are higher in foreign‐owned firms than in domestic ones, the wage gap between skilled and unskilled workers is wider. It follows that promoting foreign investment enhances productivity. In addition, due to the greater demand for skilled workers, policies such as training schemes would be conducive to raising productivity still further, while other social policies could help to mitigate the wage inequality effects.     

Innovativeness,offshoring and black economy decisions. Evidence from Italian manufacturing firms

Following recent models in international trade this paper examines the characteristics that businesses should possess to pursue internationalization strategies. We do this in the peculiar context of Italy, the G-7 country with the largest share of the black economy in GDP. Specifically, we posit that Italian manufacturing firms may use three strategies to counter the competitive threats by emerging economies: (i) improve the innovative content of their products (ii) venturing into offshoring, or, alternatively, (iii) entering the black economy. We estimate the impact of these moves with firm-level data drawn from two waves of the Italian Manufacturing Survey (IMS) covering a six-year period (1998–2003). We find that offshoring firms are larger, more innovative, have higher capital/labour ratio and are located in provinces where the share of the black economy is lower. Firms belonging to provinces in which the share of the black economy is larger are less likely to choose the internationalization mode. The offshoring-black economy nexus bears relevant policy implications. In particular, vis-à-vis their offshoring companions, firms choosing to enter the black economy may be producing negative spillover effects by lowering productivity and the propensity to innovate.     

Trade and Innovation in Services: Evidence from a Developing Economy

Studies on innovation and international trade have traditionally focused on manufacturing because neither was seen as important for services. Moreover, the few existing studies on services focus only on industrial countries, even though in many developing countries services are already the largest sector in the economy and an important determinant of overall productivity growth. Using a recent firm‐level innovation survey for Chile to compare the manufacturing and ‘tradable’ services sector, this paper reveals some novel patterns. First, even though services firms have on average a much lower propensity to export than manufacturing firms, services exports are less dominated by large firms and tend to be more skill intensive than manufacturing exports. Second, services firms appear to be as innovative as – and in some cases more innovative than – manufacturing firms, in terms of both inputs and outputs of ‘technological’ innovative activity, even though services innovations more often take a ‘non‐technological’ form. Third, services exporters (like manufacturing exporters) tend to be significantly more innovative than non‐exporters, with a wider gap for innovations close to the global technological frontier. These findings suggest that the growing faith in services as a source of both trade and innovative dynamism may not be misplaced.     

Outsourcing and the US Labour Market

There is worldwide concern about the vulnerability of the current labour force to displacement by future imported services. In the USA, some have suggested that as much as one‐third of the workforce might be vulnerable to such outsourcing. However, the labour market impacts of this displacement are difficult to assess using purely analytical or statistical approaches. In this paper, simulation methods are used to understand how sensitive the US economy and labour market are to increases in services imports. Specifically, the scenario examined assumes that the share of imported services in total employment increases from 0.8 per cent to 7.25 per cent over a time horizon in which workers are unable to change occupations. In response, it is found that all industries increase their use of imported services and their use of the composite input that is comprised of imported services and tradable labour. With the exception of legal workers, all workers in tradable occupations experience declines in their real wages. Demand for non‐tradable occupations labour rises in the industries that expand the most, while demand falls in shrinking industries. The non‐tradable occupations that are used intensively in the shrinking industries experience declines in real wages, while the real wages rise for workers in non‐tradable occupations used intensively in the expanding industries.     

The Trouble with Offshoring: Static and Dynamic Losses in the Presence of Unemployment

This study provides theoretical support for the popular objection to offshoring, whereby firms at home employ services of labour located abroad. In the presence of unemployment, our analysis highlights welfare losses from offshoring – not only for the static case of a fixed stock of capital, but also for the dynamic one of optimal saving and investment. We compare these static and dynamic losses to the gains that would instead arise under full‐employment conditions, assumed by most of the theoretical literature on offshoring. Our results suggest that public concerns over offshoring are justified when unemployment is taken explicitly into account.     

China,India and the Commodity Boom: Economic and Environmental Implications for Low‐income Countries

The international role of China has risen steadily for two decades – and has become even more important in the current global recession. The growing supply of labour‐intensive manufactured exports from China has been accompanied by a huge expansion in its imports both of raw materials and of skill‐intensive manufactured parts and components. This ‘offshoring’ of intermediates production by a large, labour‐abundant economy has economic and environmental implications for other developing economies. More recently, the rapid expansion of the Indian economy and trade indicates that it too will soon exert similar effects on global markets. We sketch a model showing how the growth of these developing‐country ‘giants’ generates adjustment pressures on other developing economies. We discuss in particular how differences in relative factor endowments of resource‐rich economies can produce quite different outcomes in the context of product fragmentation and expanding commodity trade. We also explore the effects on production, trade, environment and prospects for future growth in resource‐rich economies, particularly in the context of weak institutions and other market failures. We illustrate these different impacts by considering the cases of Indonesia, Malaysia and Thailand and highlight implications for growth, development and policy.     

Exposure to the new wave of offshoring: An unemployment perspective

This paper examines the impact of increasing service offshoring in a two‐sector economy. We find that it leads to lower domestic unemployment if the marginal task‐specific offshoring cost in the service sector is sufficiently large. Under this condition, the jobs created due to enhanced productivity outweigh the jobs that are destroyed. The reduction in unemployment increases the cost of hiring domestic workers, thus encouraging firms in the manufacturing sector to increase their offshoring scale and productivity. This, in turn, increases their cost savings and may lead to a further decrease in unemployment. Hence, complementarity between two sectors’ offshoring activities may emerge. We calibrate the model using economic parameters from Belgium, and the calibration results predict varied unemployment trends and impacts on manufacturing‐sector offshoring activities with different task‐specific offshoring cost schedules.     

Age Structure and Trade Openness: An Empirical Investigation

This study focuses on the relationship between age structure and trade openness. We hypothesise that a higher share of the working‐age population in the total population increases trade openness, because the dependent population tends to spend more than the working‐age population on non‐tradable goods such as education and medical services. We estimate the effects of age structure on trade openness using panel data for 85 countries from 1991 to 2010. The empirical results show that the share of the working‐age population has a positive effect on trade openness. An increase in the share of the working‐age population is considered to be one factor that contributed to an increase in trade openness in the sample period.     

Export Spillovers: Opening the Black Box

This paper studies the importance of export spillovers in a firm's decision to enter specific export markets and extends the current state of the literature by assessing different mechanisms through which they may occur, namely (i) labour movement, (ii) intra‐industry spillovers and (iii) inter‐industry linkages. We do so by exploiting a unique data set covering the universe of manufacturing firms in Denmark for the period 1995–2006 which combines transaction‐level export data, firm accounting data, employer–employee linked data and information from yearly input–output tables. We corroborate the literature on export spillovers by presenting robust evidence of destination‐specific export spillovers. The results suggest that labour mobility as well as intra‐ and inter‐industry linkages (backward linkages) are important channels for export spillovers, while presenting heterogeneous effects across firms of different size and export markets.     

Trade in High-Tech Services

This paper examines the size, scope, and potential implications of trade in high-tech services in the U.S. The results suggest that many service activities are tradable, tradable service activities tend to employ more educated workers and pay higher wages, and high-tech services account for a large share of service activities that are tradable. Service exporters are more prevalent in high-tech industries with larger establishments and higher wages. Within industries, service exporters tend to be larger, pay higher wages, and are more productive. Tradable service activities seem consistent with U.S. comparative advantage and, as a result, less likely to be vulnerable to offshoring. Consistent with this, recent employment growth in tradable service industries is not significantly different than employment growth in non-tradable service industries.     

Privatisation and the unusual case of Belarusian accession to the WTO

The accession negotiations of Belarus to the WTO are unusual since, due to its obligations in the Eurasian Economic Union, WTO accession is not expected to impact its tariffs or formerly substantial trade‐distorting agricultural subsidies. Nonetheless, we estimate that WTO accession will increase welfare by 9.9% of consumption in Belarus. We show that inclusion of: (i) foreign direct investment; (ii) reduction in non‐discriminatory barriers against services providers; and (iii) our model with imperfect competition and endogenous productivity effects together produce estimated gains eleven times larger than a model of perfect competition with only cross‐border trade in services. Our analysis is enabled by our production of a data set on both discriminatory and non‐discriminatory barriers in services and their ad valorem equivalents. Based on a new data set on labour productivity by sector and type of ownership, in our central model, we estimate that privatisation will increase welfare by 35.8% of consumption. We find substantial variance in the estimated gains from privatisation depending on model assumptions, but all the estimates of the impacts of privatisation indicate substantial welfare gains.     

Does Outsourcing to Central and Eastern Europe Really Threaten Manual Workers’ Jobs in Germany?

Starting from the observation of significant within‐industry skill‐upgrading, this paper analyses how international outsourcing has affected the relative demand for manual workers in German manufacturing during the 1990s. We combine trade and input‐output data to disentangle international outsourcing and trade in final goods and differentiate between the effects of narrowly and broadly defined outsourcing towards Central and Eastern Europe (CEEC), the European Union (EU15) and the rest of the world. Accounting for the endogeneity of international outsourcing by applying instrumental variable techniques, the empirical analysis showed that international outsourcing is indeed an important explanatory factor for the observed decline in relative demand for manual workers in German manufacturing. Particularly, outsourcing towards CEEC plays a major role, irrespective of whether a narrow or wide measure of outsourcing is applied. Using a narrow outsourcing measure and controlling for the adverse demand effects of skill‐biased technological change, time‐changing industry characteristics, wages as well as industry unobserved characteristics, international outsourcing towards CEEC is found to have lowered the manual workers’ wage bill share by 2.7 per‐centage points between 1991 and 2000. In its magnitude this effect is comparable to the skill‐biased effect of technological progress, as captured by our controls. Outsourcing towards countries outside CEEC and outside the EU15 is found to have small negative effects on the relative demand for manual workers, but only if one follows the broad definition of international outsourcing. Outsourcing towards the EU15 is, however, always found to be insignificant.     

The rise of the machines: Capital imports and real manufacturing wages in 57 nations

Outward-oriented policy reform has attracted a large number of academics to the study of the trade-labour market nexus. One of these fields has focused on capital intensive (machinery) imports and its effect on manufacturing wages. The skill-enhancing-trade (SET) hypothesis was put forth to explain a potential relationship where an inflow of capital imports results in increased demand for skilled labour and decreased that of unskilled labour, and thus resulted in a rise in skilled wages and a decrease in their unskilled counterparts. This study revisits this hypothesis with a panel from the manufacturing sector of 57 nations. We improve upon previous studies in a number of ways. We add developed nations to the sample and examine capital imports from rich countries as well as the rest of the world. This takes into account the prominence of vertical production networks in international trade. We adhere closely to the neo-classical trade model and employ definitions of skilled and unskilled workers that capture the production process of particular items. Finally, we fit a robust dynamic panel data model that accounts for the endogeneity of the determinants of trade and wages. In this way we test whether the SET hypothesis is generally applicable as opposed to previous studies which use an ad hoc selection of countries and variables. We find that the SET hypothesis is not driving changes in manufacturing wages. Instead, worker productivity and GDP per capita explain these labour market outcomes.
