LINK Abstract: Research background: In the era of globalization, there is a need to address decent work deficits in Global Value Chains (GVCs). The forms of working conditions reveal a broad dispersion of contents. The literature review exposes hardly any Europe-focused research assessing the socioeconomic impact of global production links and going beyond their pure economic effects assessed in terms of employment, productivity or wages.
Purpose of the article: This paper investigates how  involvement in GVCs affects labour standards. In particular, we assess how the integration into GVCs impacts the probability of having indefinite type of employment contract, which stands for one of the decent work indicator. Moreover, we draw individual and firm-level characteristics determining the type of employment contract.
Methods: We use linked employer-employee data from the Structure of Earnings Survey merged with industry-level statistics on GVCs based on World Input-Output Database — the sample is composed of over 5 million workers from 10 Central and Eastern European countries (CEEC) observed in 2014. The involvement into GVCs is measured using a novel approach based on the concepts of global import intensity (GII). We employ logistic regression with robust standard errors.
Findings & Value added: Controlling for individual and firm-level characteristics (sex, age, education level, length of service in enterprise, size of the enterprise) we find that greater integration into GVCs increases the probability of having temporary type of employment contract, mainly in tradable sectors. However, across CEE countries the relation between GVC and employment type is mixed. In this way we expand the existing literature by reporting the effects of GVCs on labour standards in CEEC.

LINK Abstract: Using rich individual-level data on workers from 28 European countries, this study provides the first so extensive cross-country assessment of wage response to global production links within GVC in the period 2005–2014. Unlike the other studies, the authors (i) address the importance of backward linkages in globally integrated production structures (capturing imports of goods and services needed in any stage of the production of the final product); (ii) measure occupational task profile of workers with country-specific indices of routinisation; (iii) compare the impact of global production links on wages between workers from Western, Central-Eastern and Southern Europe; employed in manufacturing and non-manufacturing sectors; (iv) account for direct and indirect dependence on GVC imports from developing and high-income countries. The study takes into account the potential endogeneity issues. The results suggest that global import intensity of production exhibits negative pressure on wages in Europe. This effect concerns mainly workers from Western Europe employed in manufacturing and is driven by production links with non-high income countries but our counterfactual estimates suggest that the effect is economically small.

LINK Abstract: This paper contributes to the empirical literature on the relationship between “export variety” (export diversification) and economic development by relaxing the assumption of cross-country independence and allowing for spatial diffusion of shocks in observed and unobserved factors. Export variety is measured for a balanced panel of 114 countries (1992–2012) using very detailed information on their exports (HS 6-digit product level). The estimation results of a dynamic spatial panel data model confirm the relevance of spatial network effects in export diversification: indirect effects (spatial spillovers) strongly reinforce direct effects, while spatial proximity to large countries accelerates the diversification process. In about 10 years the whole space–time diffusion of the diversification shock is widely completed. We reveal that the long run spillover impact from European countries is much higher than from other countries such as the United States, Japan, or the BRICS (Brazil, Russia, India, China, and South Africa).

LINK Abstract This paper uses a multi-country microeconomic setting to contribute to the literature on the nexus between production fragmentation and wages. Exploiting a rich dataset on over 110,000 workers from nine Eastern and Western European countries and the United States, we study the relationship between individual workers’ wages and industry ties into global value chains (GVCs). We find an inverse (but weak) relationship between the degree of industries’ involvement in GVCs and wages. Workers employed in routine occupations clearly earn less, but it is difficult to attribute it to the role played by the involvement of their countries and industries in global value chains.

Parteka A. (2018) Import Intensity of Production, Tasks and Wages: Microlevel Evidence for Poland. Entrepreneurial Business and Economics Review. 6(2): 71-89 (listed in Web of Science - Emerging Sources Citation Index)

LINK Abstract: This article relates to recent literature on labour market consequences of production fragmentation within Global Value Chains, analysed in the presence of workers’ heterogeneity and differences in the task content of jobs. The main aim is to assess if there is a relationship between wages of Polish workers and the degree of Polish production dependence on imported inputs. Using microdata from EU-SILC on workers from Poland observed in 2008-2014, we estimate a Mincerian model, augmented by a measure of task content of occupations and the industry level index of the import intensity of production computed with input-output data and accounting for good’s production sequence). IV estimation is employed to account for potential endogeneity between the import intensity of production and wages. Regression results suggest that negative relationship between wages of Polish workers and the dependence of their sector of employment on foreign inputs is magnified by the routinization level of the occupation. Hence occupation-specific task requirements play a role. Implications & Recommendations: It implies that not all the Polish workers are affected in the same. The movements towards jobs with higher degree of non-routine content could protect against negative wage effects of fragmentation. The relationship between wages in Poland and the reliance on foreign inputs and GVCs links has not yet been studied from the micro-level task-based perspective. This article fills in this gap.

LINK Abstract: The study presents the empirical analysis of firms’ involvement in different forms of internationalisation: export, indirect export, import, indirect import and finally simultaneous exporting and importing. The analysis is based on firm-level data from the World Bank Enterprise Survey (March 2017 release). The empirical part is divided into two stages. Firstly account is taken of firms’ heterogeneity and then a Melitz type analysis of the firms’ likeliness of being involved in international activity is performed. Secondly the sample of firms is limited to only those involved in the internationalisation process and then a regression is carried out with the export/import intensity being the dependent variable. The results indicate that determinants of the foreign markets are different from those connected with trade intensity with the exception of the foreign ownership which is the only one associated in the same way with involvement in internationalisation and with its intensity.

LINK Abstract:  The aim of this research is to reanalyse the possible impact of production fragmentation on employment using the newest World Input-Output Database (WIOD) release (2016) and recently proposed by Timmer, Los, Stehrer and de Vries measure of production fragmentation which traces the imports needed in all stages of production. This study is provided on country-industry level for 56 industries and 41 countries for the years 2000-2014. The estimated model is based on augmented labour demand function. Our empirical results show that certain countries and sectors can in fact feel the negative impact of increasing production fragmentation on labour demand.

LINK Abstract: The main aim of this article is to present how the heterogeneity of workers, firms, and tasks can be incorporated into empirical international trade analysis. In particular, we provide an empirical example in which we aim to quantify the reliance on foreign value added (FVA) within Global Value Chains (GVC) on wages.We estimate a Mincerian wage model augmented with a measure of foreign value added drawn from international input-output data. We employ econometric modeling with instrumental variable (addressing the endogeneity between trade and wages) and estimated through weighted regression with cluster-robust standard errors. Controlling for individual workers and job characteristics, we find the negative correlation between FVA and wages. The effect is conditional on the skill and task typology (affecting mostly workers performing routine tasks).

LINK Abstract: In this article we quantify the magnitude and evolution of gender wage differentials in Poland over the years 2005–2014 using microlevel data from EU-SILC database (Statistics on Income and Living Conditions). It the study gender wage gap is examined through quantile regression analysis. It is shown that the gender wage gap varies along the wage distribution with workers’ skills heterogeneity playing a role. Additionally, the decomposition technique reveals that the unexplained wage gap is highest for the top of the distribution. Finally, the results suggest a slow decrease in discriminatory component of the wage gap –only for the bottom of the wage distribution.

LINK Abstract: The aim of this paper is to present key facts concerning trade in the value added of those countries participating in the Transatlantic Trade and Investment Partnership (TTIP). In particular, we describe how involvement in global production networks (GPN) varies across EU countries with respect to the United States. After describing the key concepts, we locate them within recent economic literature and present the results of an empirical exercise, comparing the domestic and foreign content of the analysed countries’ exports.

 LINK Abstract: The main aim of this article is to assess the implications of involvement in global value chains (GVC) on sectoral productivity growth from the international perspective. Our panel data analysis covers 40 countries, 20 industries (13 manufacturing and 7 services sectors) in the period 1995–2011. Estimation results suggest that there is a positive link between TFP growth and the involvement of sectors in global value chains (measured as a share of foreign value added in exports). In particular, positive impact of foreign value added on TFP growth takes place mainly in manufacturing sectors. The results are robust to changes in productivity growth measurement.

 LINK Abstract:  This paper examines the relationship between the relative position of industries in Global Value Chains (GVCs) and wages in ten Central and Eastern European countries in the period 2005-2014. We combine GVC measures of global import intensity of production, upstreamness  (distance  from  final  use),  and  the  length  of  the  value  chain  (based  on WIOD) with micro-data on workers from EU-SILC. We find that the wages of CEEC workers are higher when their industry is at the beginning of the chain, far from final demand (high upstream) or at the end (low upstreamness – sectors close to final demand) than in the middle. Secondly, wage changes depend on the interplay between upstreamness and GVC intensity. In sectors close to final demand, greater production fragmentation, measured either by global import intensity or by vertical specialisation, is associated with lower wages. Higher upstream, this effect is not sustained.

 LINK  Abstract: This paper investigates how involvement in Global Value Chains (GVCs) affects working conditions. We use linked employer-employee data from the Structure of Earnings Survey merged with industry-level statistics on GVCs based on the World Input-Output Database. The sample consists of almost 9 million workers in 24 European countries in 2014. Given the multidimensional nature of the dependent variable, we compare the estimates resulting from a Mincerian wage model with zero-inflated negative binomial regressions that analyse other aspects of working conditions (overtime work and bonus payments). As to the impact of production fragmentation on social upgrading, wages prove to be negatively related to sectoral GVC involvement. Workers in sectors more deeply involved in GVCs have lower and less stable earnings, meaning worse working conditions; on the other hand, they are also less likely to have to work overtime, which one may see as a sign of better labour standards.

 LINK Abstract:  In this paper we examine the linkages between involvement in global value chains (GVCs) and gender wage inequalities. We use merged data from the wide-ranging Structure of Earning (SES) database and the World Input Output Database (WIOD) for the years 2002, 2006, 2010 and 2014 covering manufacturing industries in 18 European countries. We employ a wealth of information on employees’ personal and company characteristics and a sectoral variable reflecting involvement in GVCs measured with foreign added value embodied in exports (FVA/Exp.) We augment the Mincerian regression with the GVC variable and report on gender wage discrimination among European employees. The results indicate that the wages of workers employed in sectors more involved in GVCs are lower. However, the relationship between GVC involvement and wages differs with respect to gender: women are more affected by the negative impact of greater trade involvement than men. There is some education/skill/occupation heterogeneity, with workers with a medium level of education and medium skills being most affected. Finally, our results show different patterns for concentrated and competitive industries: a greater female wage disparity due to GVC intensification is observed for the former.

 LINK Abstract:  This  article  examines  the  overall  effect  of  global  value  chains  (GVCs)  on  labour  market outcomes,  namely  wages  and  labour  demand.  The  analysis  exploits  the  World  Input-Output Database (WIOD, 2016 release) covering 43 countries and 54 sectors from 2000 to 2014. GVC involvement is measured by the recently developed GVC participation indexes (based  on  both  backward  and  forward  linkages)  and  relative  GVC  position  (Wang  et  al., 2017a, 2017b).  The  estimates  employ  the  three-least-squares  method.  The  results  indicate that  GVC  position  is  negatively  correlated  both  with  wages  and  with  employment,  while the effect of GVC participation as such depends on whether backward or forward linkages are  considered.  We  find  some  heterogeneity  between  countries  (middle-versus  high-income) and sectors (manufacturing versus services). Importantly, the labour market effect of  involvement  in  GVCs  is  different  from  the  channel  of  traditional  trade  in  which  the production process does not cross national borders.
