Does global value chain participation improve firm productivity? A study of selected ASEAN developing countries

This paper examines the impact of local firms’ participation in global value chains (GVCs) on productivity by considering three different patterns of GVC participation. We conducted a DID-PSM estimation involving three countries, Indonesia, the Philippines, and Vietnam, and 17 manufacturing sectors in 2009 and 2015 in a panel framework. We found an endogenous relationship between firm productivity and GVC participation: firms that enter GVCs have high productivity before participating in the GVCs (selection effect), and only Indonesian firms that entered GVCs had high productivity growth after joining GVCs (learning effect). These two effects were only found for firms that both import intermediate goods and export output and not for firms that only either import or export. We also found that indirect exporting does not improve a local firm's productivity. Several recommendations are made to help firms and governments facilitate the participation of firms in GVCs.     

Institutions and participation in global value chains: Evidence from belt and road initiative

The “One Belt and One Road” (OBOR) initiative proposed by China aims to promote highly efficient resource allocation, deep regional integration, and extension of global value chains (GVCs). The main challenges faced by OBOR include large variations in regional institutions and a high degree of political instability among OBOR countries. This paper examines the linkage between regional institutions and GVC participation. First, we show that OBOR countries have much weaker institutions and less GVC participation than non-OBOR countries. Second, we find that institutions play important roles in GVC participation in both OBOR and non-OBOR countries. Improved regulatory quality, political stability, government effectiveness, and rule of law can significantly promote GVC participation in institutionally sensitive industries. Finally, a firm-level analysis that is based on the World Bank's Enterprise Survey Data indicates that better quality local institutions encourage firms to participate in GVCs.     

Do firms' political connections depress the union wage effect? Evidence from China

Our paper reconciles the debated literature on the role of the Chinese unions by exploring the heterogeneous effects of unionization on wages in firms with and without political connections. We utilize a survey of 1268 firms in 12 cities to verify our hypothesis that wages increase due to unionization, but this union wage effect is significantly depressed by firms' political connections. Through a detailed analysis of the mechanism behind the empirical results, we conclude that unions increase workers' wages by strengthening the bargaining power of workers, while this bargaining power can be weakened by firms' political connections. Our main conclusion is robust to a series of robustness checks. Moreover, the results from quantile regressions inform us that the union wage effect and the role of political connections may vary along with the firms' wage distribution. Our findings suggest that the solution to further increase wages for low-wage workers and reduce wage inequality is to make the labor union an independent organization which can freely bargain with firms in terms of workers' wages and benefits, rather than an agency subordinate to the government whose role can be affected by the government support and undermined largely by firms' political connections.     

How does intermediate consumption affect GVC positions? - A comparison between China and US

Using the data of the World Input and Output Table (WIOD) from 2000 to 2014, this paper measures the positions of China and the US in the global value chains (GVCs). We develop a new dual structural decomposition method to analyze the drivers behind the GVC position differences between the two countries from the perspective of intermediate consumption. The results show that (1) China is moving away from both end-users and primary factors, while the U.S. is moving towards both ends of the GVCs. The gap between China and the US in GVCs is widening. (2) About 40% of the difference between the GVC positions of China and the US can be attributed to the difference in industrial structures between the two countries, and the remaining 60% is related to the difference in the GVC positions of the same industries between the two countries. (3) China's three major industries are all embedded in a further GVC position from households, governments, and investors (HGIs) than the US, but they are formed for completely different reasons. The domestic direct effect is the main reason for the resource industry, the multiplier effect is the main driver for the manufacturing industry, and the domestic linkage effect is the main factor for the service industry. (4) The different roles of the two countries in the international division of labor result in the difference in the two countries' consumption coefficients of the manufacturing and service sectors, and the asymmetric interaction between industries ultimately leads to the differentiation in the GVC positions of the industries between the two countries.     

Backward participation in global value chains and exchange rate driven adjustments of Swiss exports

This paper examines the effect of exchange rate movements on export volume, export revenues and propensity to export taking into account the extent of foreign value added content of exports (“backward integration”) in global value chains (GVCs). Using both product-level and firm-level panel data, our results suggest that Swiss exports (intensive margin) and the export probability (extensive margin) are negatively affected by a currency appreciation. However, this adverse effect is mitigated in sectors and firms that are more integrated in GVCs, which could be explained by the “natural hedging” of exchange rate movements. Our findings are robust to the use of different measures of natural hedging and GVC integration and also hold across various specifications and estimation methods that control for sample selection, firm heterogeneity, heteroskedastic errors and persistence in export behavior. The dynamic specifications also reveal that export hysteresis driven by a currency appreciation is a concern particularly for firms that are not established in export markets.     

Tariffs,relative prices and wage inequality: Evidence from China

This paper, based on data from China after its membership into the World Trade Organization (WTO), shows the co-existence of a fluctuating skill premium and rises in wages for both skilled and unskilled labor. Our research provides one specific factor, the tariff reduction biased toward unskilled labor-intensive sectors, to explain and quantify the magnitudes of skill premium dynamics using the mandated-wage approach. The empirical evidence indicates that sector-biased tariff reductions have widened wage inequality in China through their effect on product prices. World price competition, on the other hand, has contributed to declining wage inequality via product prices, which is consistent with the endowment-based expectations of China's integration into the more skilled-labor abundant world.     

全球价值链参与对出口产品质量的影响

基于微观企业数据,研究了全球价值链分工对出口产品质量的影响,得到以下结论：从整体上看,企业GVC上游参与程度提高有助于提升出口产品质量,而下游参与程度提高阻碍了出口产品质量的提升。从分组检验中看,企业GVC上游参与度提高对出口产品质量有稳健的正效应;而下游参与度提高的效应对于不同特征的组别存在差异,加工贸易企业GVC下游参与度提高有利于产品质量的提高,而一般贸易企业GVC下游参与度提高不利于产品质量的提高;外资企业GVC下游参与度提高的质量效应较明显,而对于国有企业该效应较弱;低技术类型企业GVC下游参与度的提高有助于产品质量提升,而对中、高技术类型企业来说则有显著的负效应。文章还发现GVC下游参与通过"中间品效应"、"溢出效应"渠道提升了出口产品质量。     

Upstreamness,exports, and wage inequality: Evidence from Chinese manufacturing data

In this paper we investigate within-firm wage inequality across heterogeneous industries that hold different positions in the domestic value chain, and across heterogeneous firms that have different exposure to trade. We find that the wage inequality problem is more severe in upstream industries than in downstream ones, and among firms with greater exposure to trade (i.e., larger export share of sales). Our findings support both classic and new new trade theories on wage inequality. In downstream industries where Chinese firms are typically engaged in processing and assembly work with intensive use of unskilled labor, trade leads to less wage inequality within firms. However, trade also introduces pro-competitive effects which usually benefit exporters and their skilled labor. The results hold after various checks and controls for robustness.     

Wage inequality dynamics and trade exposure in South Korea

South Korea has experienced a great U-turn in its inequality trends during the past few decades. In this paper, we explore the role of international trade in its wage inequality dynamics over the 1998–2012 period, using a unique household panel survey. Our analysis reveals that most of the overall wage inequality occurs within sectors and educational groups rather than between them. However, the share in total inequality of the “between” variation across sectors and educational groups has moderately increased over time. Furthermore, we document that almost the entire aggregate wage inequality in both manufacturing and services occurs within different trade-exposure categories rather than between them, and this pattern is persistent through time. These results suggest that international trade might not be the main driving force behind the rising wage dispersion in South Korea in the last two decades.     

Product differentiation,export participation and productivity growth: Evidence from Chinese manufacturing firms

In this paper, we investigate how the degree of export participation and product differentiation affect firms' productivity growth through learning-by-exporting. We extend the model of Melitz and Ottaviano (2008) to endogenize the effort firms allocate to learning. This effort choice depends on both the degree to which firms enter export markets and the extent to which products are differentiated across producers. Using a firm-level dataset from China's manufacturing industries, we implement propensity score matching methods to test the model's predictions. Our results indicate that the degree of export participation is positively correlated with TFP improvements. Simultaneously, we empirically verify that firms exporting less differentiated products experience faster TFP growth than those exporting more differentiated products.     

Skilled-Labor Intensity Differences Across Firms,Endogenous Product Quality,and Wage Inequality

This paper proposes a theory to explain the relative wage-rate increase for skilled labor that results from trade liberalization that relies on within-sector reallocations of production resources (skilled and unskilled labor) across firms. Motivated by some stylized facts, in a model with firm heterogeneity, including firms that differ in their skill intensity even within a narrowly defined industry, firms with relatively high skill intensity that are more likely to be exporters, and a positive association between a firm’s skill intensity and its product quality, I develop a general equilibrium model where firms with a higher skill intensity endogenously choose a higher-quality product, and tend to be more profitable. In this framework, a reduction in trade costs allows members of the workforce to reallocate to more efficient firms that produce higher-quality products, using their skilled labor more intensively, resulting in a rising skill premium. The main sources of the increasing wage inequality that followed trade openness are a positive link between a firm’s skill intensity, its product quality, and quality competition.     

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.     

女性家庭地位上升、生育率差异与工资不平等

文章通过把女性生育率和劳动力市场性别歧视内生化,为理解工资不平等的发展趋势提供了新的视角。研究表明,随着女性家庭地位上升和生育率下降,企业性别歧视程度降低,于是工资不平等将受女性技术工人和非技术工人生育率差异的影响。如果生育率差异扩大,那么技能溢价将上升。当性别工资差距可以影响女性家庭地位时,生育率下降将扩大女性家庭地位对技能溢价的影响。这一影响机制在关于我国农民工调查数据的实证研究中得到了验证。     

Product Scope and Productivity: Evidence from India's Product Reservation Policy

Protections for small enterprises are commonplace in developing countries. How do these policies affect overall industrial performance? Using exogenous variation in the timing of an Indian policy dismantling laws that “reserved” certain products for exclusive manufacture by small firms, we identify the effect of the dereservation policy on size, productivity, product churning, and other industry dynamics. Following the change, we find that firms significantly altered their product lines, leading to the reallocation of productive factors, increasing exits, and increasing total factor productivity. These effects were driven by new entrants moving into the formerly restricted product space, and in particular by multiproduct firms. Our findings underscore the importance of intrafirm heterogeneity on the impact of size‐contingent regulations, as firms' product line dynamics can be an important dimension of productivity growth.     

Why Do Foreign-Owned Firms Pay More? The Role of On-the-Job Training

While foreign-owned firms have consistently been found to pay higher wages than domestic firms to what appear to be equally productive workers, the causes of this remain unresolved. In a two-period bargaining framework we show that if training is more productive and specific in foreign firms, foreign firm workers will have a steeper wage profile and thus acquire a premium over time. Using a rich employer-employee matched data set we verify that the foreign wage premium is only acquired by workers over time spent in the firm and only by those that receive on-the-job training, thus providing empirical support for a firm-specific human capital acquisition explanation.

Efficiency Wages,Interfirm Comparison,and Unemployment

The paper presents an efficiency wage model where worker effort depends on own wages relative both to wages of other workers in the firm and to similar workers in other firms. First, we show how the Solow conditions are modified if internal comparison effects are at work. Second, we discuss the effect of internal wage comparison on wage inequality within firms. Third, we study unemployment and relative wage determination within a general equilibrium model, and analyze the effect of technological change and various tax policies on equilibrium unemployment and relative wages. Finally, the short-run effects of aggregate demand shocks are analyzed.     

Art of the Deal: The Merger Settlement Process at the Federal Trade Commission

This paper models the modern merger review process in which an enforcement agency, here the Federal Trade Commission (FTC), interacts with the acquiring firm to determine the outcome of antitrust regulation. Our empirical implementation of a game theoretic analysis tests whether decisions are driven by the costs and benefits of the proposed enforcement initiative as well as whether firms' responses are colored by competitive and institutional considerations. With respect to firms, the results suggest that mergers are driven by the opportunity to capture efficiencies, In contrast, the structural (anticompetitive) characteristics of mergers do not seem to impact firms' litigation decisions. Firms, however, are deterred from fighting the FTC by the potential negative impact on their reputations. In addition, “hostage effects” associated with the size of the noncontroversial portion of acquisitions held up by the FTC's competitive concerns also affect firm decisions.     

Global value chains and servicification of manufacturing: Evidence from firm-level data

Recent literature on global value chains (GVCs) has mainly focused on manufacturing firms’ global sourcing and investment strategies. Our question here is that, if the manufacturing firms established foreign manufacturing plants and engaged in sourcing inputs and exporting outputs, have they changed their domestic employment composition toward service workers? This is what we call servicification of manufacturing firms in this paper. To answer this question, using Korean firm-establishments matched data, we examine changes in the shares of service employment in manufacturing firms from 2008 to 2013, when those firms are participating in both import-and-export and foreign direct investment (i.e., GVC firms). We find that the two-way trading firms that own manufacturing plants in foreign countries—and particularly in nearby foreign countries—have changed their domestic employment structures to increase the number of service workers they employ. Moreover, the relatively greater increase in the share of R&D workers than of wholesale-and-retail workers serves as further evidence of the servicification of domestic manufacturing. Overall, our findings suggest that Korean firms who engage in GVCs through both trade and foreign direct investment have reorganized domestic labor structure to be able to provide high value-added headquarter services for their manufacturing plants that are closely located in foreign countries.     

Do excessive wage increases raise imports?: Theory and evidence

This paper uses a model of trade in vertically differentiated products to examine the effects of “excessive wage” increases (i.e. above productivity) on the volume of commodity imports. The model predicts that if the domestic country has comparative advantage in producing high quality varieties of some products, then “excessive wage” increases may result in a decrease in the volume of imports for these products. The empirical validity of the model's predictions is demonstrated with the use of disaggregated Japanese import data for the period 1967–1995. We also find that the aggregate volume of Japanese imports is not responsive to “excessive wage” changes.     

Experimental Evidence of the Impact of Increasing Auditors' Legal Liability on Firms' New Investments*

This laboratory market study examines the potential effect of increasing auditors' liability on firms' new investments. The experimental hypotheses are derived from Shibano's 2000 model, which predicts that an increase in auditors' liability will decrease the frequency of audit failures and may decrease firms' new investments if the liability level is “excessive”. Results from three experimental market settings (with low, medium, and high liability levels) suggest two major conclusions. First, firms' new investments increase significantly when auditors' liability level increases from low to medium, and decrease significantly as the liability level increases from medium to high. This result provides support for the argument that adequate auditor liability is necessary to motivate firms to invest in new projects. Excessive liability, however, may discourage firms from making new investments. Second, the frequency of audit failure decreases insignificantly when auditors' liability increases. These two results have an important policy implication: the benefit of imposing high liability on the auditor (i.e., an insignificant decrease in audit failure) may be more than offset by its cost (i.e., a significant decrease in new investments).
