ICT,offshoring, and the demand for part-time workers: The case of Japanese manufacturing

This paper examines the effects of information and communication technology (ICT) and offshoring on the skill demand in Japanese manufacturing. One of the contributions of this paper is that we focus explicitly on the demand for low-wage part-time workers, which we call low skilled workers. Estimating a system of variable factor demands for the period 1980–2011, we find that industries with higher ICT stock shifted demand from middle-low to middle-high and low skilled workers. Offshoring is associated with the increasing demand for high skilled workers but it has insignificant effects on the demand for middle-high, middle-low, and low skilled workers. The results together suggest that the increasing demand for low-wage part-time workers can be attributable to ICT in Japan.     

Employment Effects of Offshoring across Sectors and Occupations in Japan

In the case of Japan, the studies conducted so far focus alone on firm‐level data and delve into the productivity effects and the skill upgrading between skilled and unskilled workers. Here, we carry out an empirical analysis of the employment effects of offshoring for Japanese industries on a broader classification of skills or occupations, while considering the three major sectors of the economy and taking account of both services and materials offshoring. The results suggest that various types of offshoring affect occupations differently. In particular, services offshoring tends to benefit highly skilled occupations more, while materials offshoring tends to benefit production workers instead.     

Firm-level effects of offshoring of materials and services on relative labor demand

Based on firm-level data over the period 1997–2002 for the Swedish manufacturing sector the objective of this paper is to analyze relative labor demand effects due to offshoring, separating between materials and services offshoring and also geographical location of trade partner. Overall, our results give no support to the fears that offshoring of materials or services lead to out-location of high-skilled activity in Swedish firms. Rather, this paper finds evidence that the aggregate effects from offshoring lead to increasing relative demand of high-skilled labor, mainly due to services offshoring to middle income countries.     

Multinationals, skills, and wage elasticities

The increase in foreign direct investments raises concerns about labor market consequences in many countries. It is feared that multinational firms are inclined to shift jobs abroad and increase job volatility. We use firm-level data to examine if multinationality and foreign ownership affect the wage elasticity of labor demand. Unlike previous studies, we distinguish the effect on different skill groups of employees. We find no general difference in wage elasticity between foreign and domestic firms but the wage elasticity is higher in multinational firms than in national firms, in particular for medium-skilled workers.     

Offshoring and working hours adjustments in a within-firm labor market

Although a growing body of literature identifies the within-firm redistribution effects of trade, research on the adjustment processes in within-firm labor markets remains scarce. This study analyzes the within-firm adjustment of working hours and wages by considering workers’ educational background and gender in response to a change in offshoring. Matched worker–firm panel data in the Japanese manufacturing sector covering 1998 to 2014 are used. The analysis leads to the following three observations. First, offshoring does not significantly alter the skill premium and gender gap in terms of scheduled monthly salaries and scheduled hourly wages. Second, offshoring decreases skill premium in annual hourly wages, whereas it increases gender gap in annual salaries. Third, this uneven impact on annual variables arises from the different changes in overtime working hours: college graduates work longer with a lower overtime premium, whereas female workers do not increase overtime work.     

Offshoring,wages, and heterogeneity

Considering heterogeneous responses by skill group to material and service offshoring, we examine the relationship between offshoring and the individual wages of workers in the U.S. labor market. We find that offshoring has been beneficial for high-skill workers but detrimental for middle- and low-skill workers. In particular, service offshoring, which has been widespread since 2000, has severely affected the labor market, compared to material offshoring.     

Offshoring and the Elasticity of Labour Demand

This paper examines the impact of offshoring on labour demand and labour demand elasticities for a sample of 40 countries over the period 1995–2009 using the World Input–output Database (WIOD). Estimating the conditional labour demand model we find that offshoring impacts negatively labour demand, and in particular the demand for low- and medium-educated labour, with some evidence indicating that offshoring has tended to increase labour demand elasticities. Of particular interest are results for the subsamples of developed and developing countries. Most notably, we find that the negative effects of offshoring in developed countries are largest for high-educated labour, an outcome which we show is due to the offshoring of developed countries with other developed countries.     

THE DETERMINANTS OF EMPLOYMENT: A SECTORAL ANALYSIS FOR TURKEY

This paper analyzes the effects of wages, openness, and demand on employment in the private manufacturing industry in Turkey based on panel data for the period of 1973–2001. The wage elasticity of employment increases after trade liberalization. Nevertheless, output elasticity of labor demand is higher than wage elasticity in the total manufacturing sector for the whole estimation period, and in the high- and medium-skilled sectors in the post-1980 period. Trade effects, after controlling for output, seem to have a low economic significance. The positive effects of exports on the labor intensity of production are low or are offset by labor saving effects of foreign trade, particularly in the high- and medium-skilled sectors. On the other hand, there is some evidence of a negative import effect in the low-skilled sectors, whereas in the high- and medium-skilled group a complementary relation between domestic labor and imported inputs dominates the effects.     

Offshoring and the Skill Structure of Labour Demand in Belgium

A major concern regarding the consequences of offshoring is the worsening of the labour market position of low-skilled workers. This paper addresses this issue by providing evidence on the impact of offshoring on the skill structure of manufacturing employment in Belgium between 1995 and 2007. Offshoring is found to significantly lower the employment share of low-skilled workers. Its contribution to the fall in the employment share of low-skilled workers amounts to 35 %. This is mainly driven by offshoring to Central and Eastern European countries. While most of the previous papers on this subject focus on materials offshoring, we show that offshoring of business services also contributes significantly to the fall in the low-skilled employment share. As a complement to the existing literature, we compare the widely used current price measure of offshoring with a constant price measure that is based on a deflation with separate price indices for domestic output and imports. This reveals that the former underestimate the extent of offshoring and its impact on low-skilled employment. Finally, we also find that the impact of offshoring on low-skilled employment is significantly smaller in industries with a higher ICT capital intensity.     

Labour-Market Outcomes of Older Workers in the Netherlands: Measuring Job Prospects Using the Occupational Age Structure

This paper analyses changes in job opportunities of older workers in the Netherlands in the period 1996–2010. The standard human capital model predicts that, as a result of human capital obsolescence, mobility becomes more costly when workers become older. We measure and interpret how changing job opportunities across 96 occupations affect different age and skill groups. Older workers end up in shrinking occupations, in occupations with a lower share of high-skilled workers, in occupations facing a higher threat of offshoring tasks abroad, more focus on routine-intensive tasks and less rewarding job content. This process is not only observed for the oldest group of workers, but for workers aged 40 and above. Observing older workers in declining occupations is to a large extent a market outcome, but declining job opportunities in terms of less satisfying working conditions and job tasks and content could potentially raise incentives to retire early.     

Foreign-affiliate presence and skilled labour demand

This paper investigates the effect of inward foreign investment on the relative employment of skilled labour. The extensive review of the empirical evidence shows that the results seem to be country-specific. Using Canadian industry-level panel data, the paper shows that most Canadian industries have experienced skill upgrading, and that foreign investment, as measured by FDI or majority ownership, has contributed to this development. Moreover, notwithstanding higher regulatory restrictions on foreign investment into Canadian services industries, foreign investment has had a similar impact on skill upgrading across both the services and non-services sectors. Finally, offshoring is found to only have a positive significant impact on skill upgrading in the services sector.     

Effect of intra-industry trade on skill premium in manufacturing in China

In making use of the panel data in 27 manufacturing industries, this paper examines the recent increase in skill premium in China's manufacturing. The paper argues that the recent increase in skill premium in Chinese manufacturing can be partly attributed to the decline in intra-industry trade. A reasonable explanation on this is that the decline in intra-industry trade occurred in the period studied is associated with a decrease in output. This led to a reduction in relative demand of low-skilled workers, which supports the hypothesis of the output-skill substitutability, and finally an increase in skill premium. Further, this paper finds that the negative effect of intra-industry trade on skill premium is larger for high-skilled manufacturing than low-skilled manufacturing. One more result in this paper is that the increase in capital input reduced the skill premium in Chinese manufacturing. The empirical evidence is consistent with a modified model of intra-industry trade with differentiated products and three factor inputs: high-skilled labor, low-skilled labor and capital.     

Taking technology to task: The skill content of technological change in early twentieth century United States

This paper uses new data on the task content of occupations to present a new picture of the labor market effects of technological change in pre-WWII United States. I show that, similar to the recent computerization episode, the electrification of the manufacturing sector led to a “hollowing out” of the skill distribution whereby workers in the middle of the distribution lost out to those at the extremes. OLS estimates show that electrification increased the demand for clerical, numerical, planning and people skills relative to manual skills while simultaneously reducing relative demand for the dexterity-intensive jobs which comprised the middle of the skill distribution. Thus, early twentieth century technological change was unskill-biased for blue collar tasks but skill-biased on aggregate. These results are in line with the downward trend in wage differentials within U.S. manufacturing up to 1950.     

Migrants and urban wage: Evidence from China's internal migration

Using China's 2005 1% population survey, this paper examines the wage impact on urban workers of rural to urban migration. We find that, on average, migrants increase the wages of urban workers, with the effect being magnified for more skilled urban workers. This suggests that migrants with skills similar to those of urban workers may complement them. We explore the possible channels of these effects. From the supply perspective, we find that migration inflows accelerate the occupational upgrading of urban workers, especially for low- and medium-skilled workers. From a demand perspective, as the share of migrants in the urban labor force increases, the number and output of industrial firms also increase, and firms become more reliant on low-skilled workers. The more migrants in a city, the greater the available employees for industrial firms, particularly for low-skilled employees. However, the effects on high-skilled firms are much smaller or insignificant. In addition, we find that migrants have little impact on firms' capital-labor and capital-output ratios. This suggests that firms can expand through capital adjustments to absorb inexpensive migrants, which alleviates the possible negative impact of migrants on the urban labor market.     

IMPORTED SKILL‐BIASED TECHNOLOGICAL CHANGE IN DEVELOPING COUNTRIES

This paper discusses the occurrence of skill‐enhancing technology import, namely, the relationship between imports of embodied technology and widening skill‐based employment differentials in low‐ and middle‐income countries. Generalized method of moments (GMM) techniques are applied to an original panel dataset comprising 28 manufacturing sectors for 23 countries over a decade. Econometric results provide robust evidence of the determinants of widening employment differentials in low‐ and middle‐income countries. In particular, the proposed empirical evidence indicates capital–skill complementarity as a possible source of skill bias, while imported skill‐enhancing technology emerges as an additional driver of increasing demand for the skilled workers in these countries.     

A model of trade,task offshoring and social insurance

The purpose of this paper is to study the role of social insurance design in a comparative-advantage model of offshoring and trade. To do so, we incorporate social insurance into a modified version of the Grossman and Rossi-Hansberg (Am Econ Rev 98(5):1978–1997, 2008) model by formalizing its administrative, compensation, cost, labor-supply and productivity effects. The compensation and productivity effects, which are novel, give rise to important offshoring and trade implications that can contribute to explain how social insurance provision can be sustained under globalization pressure and why similar globalization pressure can lead to different skill premia developments in Western economies.     

Regional production networks,service offshoring,and productivity in East Asia

Using the Asian International Input–Output Table (1990, 1995, and 2000), this paper explores regional production networks and offshoring of material and service inputs in East Asia. In doing so, offshoring is measured directly from the Table, which has not been used in previous literature regarding this issue. It turns out that East Asian countries source significant shares of inputs within East Asia. In addition to material offshoring, service offshoring in East Asia has become increasingly common in the era of globalization. We also evaluate the effects of this fast growing offshoring on productivity. Our econometric results demonstrate that offshoring exerts a significant and positive impact on total factor productivity in East Asia. Service offshoring, in particular, performs a more significant role than material offshoring.     

Causes of labour supply and demand mismatches in the Dutch building trades

Summary In this paper the significance of some hypotheses on possible causes of labour supply and demand mismatches is tested on data of the Dutch building trades by means of a UV analysis. In contrast with most other UV research this study does not refer to a search-theoretical framework, but focuses on skill differences between labour supply and demand. Three significant causes of labour market frictions appear to be: the development of the skill composition of labour demand, the apprenticeship possibilities and the relatively high wages of older workers. Some other hypotheses show weakly significant results: bumping-down processes, reschooling of unemployed older workers and the development of secondary labour market segments.At the moment of writing this paper the author was working at the Department of Economics, Free University, Amsterdam, The Netherlands.The author would like to thank Professor J.A.M.

Export Activity,Firm Size and Wage Structure: Evidence from Taiwanese Manufacturing Firms*

This study adopts a semiparametric smooth coefficient model to evaluate the export–wage premiums, firm size–wage premiums, and the wage gap between skilled and unskilled labor. Particular focus is placed upon widespread evidence indicating that pay levels in ‘large’ and ‘export‐oriented’ firms are higher than in their ‘small’ and ‘domestic‐oriented’ counterparts. Applying the firm‐level data for Taiwanese manufacturing firms, we find a positive export–wage premium for skilled workers and a negative export–wage premium for unskilled workers. The hypothesis of a constant export premium across firm size is rejected. While most of the export–wage premiums for skilled labor can be attributed to the small and medium firms, the large exporting firms have a significant adverse effect on wages for unskilled labor. Moreover, our results suggest that the firm size–wage premiums for skilled workers are larger than those for unskilled workers. The wage gap between the two skill groups is also sensitive to size categories.
