Non-traded goods,firm dynamics and wages in a service economy

By considering the term-of-trade and volume-of-trade effects, Jones (2012) examines the distributive effect in a competitive economy with non-traded goods. This paper reexamines the effect in an imperfectively competitive economy with firm dynamics. A rise in foreign demand can generate revenue and also mitigate market distortion, whereas skilled-unskilled wage inequality can be magnified or mitigated via the effect on firm entry or exit. Thus, how to achieve the trade-off among growth, inequality and the environment becomes an important task for government decision-makers, especially so during the pandemic of Covid-19.     

Labour unions and wage inequality among African men in South Africa

One Achilles' heel of post-Apartheid South Africa is the growing intra-racial income inequality, particularly among Africans. This paper examines the role of labour unions in explaining this phenomenon among African men given that labour markets are at the core of income inequality in South Africa. Using cross-sectional data drawn from Labour Force Surveys for 2001–10, we find a monotonically declining union wage premium. Further, our results indicate that unions have both compressionary and disequalising effects on wages. The disequalising effect dominates the compressionary effect, suggesting that unions have a net effect of increasing wage inequality among African men in South Africa. This finding implies that there is scope for unions to reduce inequality through initiatives that promote wage compression.     

Capital market distortion,firm entry and wage inequality

Distortions in the capital market are notable in developing economies like China. By building up a dual production structure with oligopolistic competition in urban manufacturing, this paper investigates the distributional and welfare effects of capital market distortions. We find that in the short run, an increase in the capital market distortion in favor of urban firms can lower both the skilled and unskilled wages. However, in the long run, the preferential policy on reducing capital cost to the urban sector attracts new entry of firms, which can worsen the skilled-unskilled wage inequality in the economy. This firm-entry effect of the capital market distortion on wage inequality is empirically confirmed for China.     

The minimum wage,exports, and firm performance: Evidence from Indonesia

This paper examines the interrelationship between changes in the provincial minimum wage, firms’ export behavior, and firms’ performance in Indonesia. In this regard, we apply a two-stage least squares regression analysis to detailed firm-level data of manufacturing enterprises during 2002–2014. We find that an increase in the minimum wage is associated with a decrease in a firm’s employment and productivity, but increase in its probability of exporting and markup. We also use the 2012 minimum wage reform in Indonesia to conduct a difference-in-difference analysis to further mitigate the potential endogeneity of minimum wage regulation. Our findings are generally robust to alternative estimation methods. Moreover, quantile regression results indicate that the average wage, firm size, and the education level of workers also affect the predictions. Above all, this study suggests that Indonesian exports and the country’s comparative advantage in international markets are not negligibly affected by higher labor costs caused by the growth in the minimum wage.     

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.     

Foreign direct investment, intellectual property rights, and wage inequality in China

This article incorporates foreign direct investment (FDI) and product differentiation in a general equilibrium trade model. The analysis shows that freer trade and FDI will upgrade China's technology, improve its skills of labor, and increase the competitiveness of local firms in the international market. At the same time, the relative wage of skilled labor to unskilled labor will rise. The size of this rise will be affected by the degree of protection for intellectual property rights. These theoretical results are consistent with empirical evidence. The analysis provides insights in coordinating policies on FDI, labor market reform, and intellectual property rights protection.     

Trade liberalization and wage inequality: Evidence from Korea

This paper investigates the heterogeneous income distribution effects of trade liberalization using Korean survey data from years of 2000–2015. Following the Stolper-Samuelson theorem most of previous research studying the effects of trade liberalization on wage differences focus on workers’ characteristics (e.g., skilled or unskilled) while heterogeneity within the same worker group has not been yet substantially investigated. To fill this gap, this paper provides empirical evidence of wage inequality across firms within the same group of workers caused by trade liberalization, potentially implied in the new-new trade models with firm heterogeneity. Employing a difference-in-differences (DID) specification, we find that the wages of unskilled workers in Korea have increased since its FTAs with more advanced countries, such as members of EU and the US, came into effect, while the effects on the wages of skilled workers are negative but not statistically significant. We also show that wage effects are heterogeneous across firms within unskilled and skilled worker groups, while the positive effects are statistically significant and largest for unskilled workers in medium-large sized firms. These findings are in line with both traditional and new-new trade models.     

International trade and within-sector wage inequality: The case of South Korea

This paper studies which factors contributed to the changes in wage inequality in Korean manufacturing over the last three decades. By adopting Akerman et al. (2013)’s decomposition method, we examine the relative importance of within-sector and between-sector wage variations in Korean manufacturing over the period of 1980–2012. Our analytic results confirm that within-sector wage variation explains the lion’s share of overall wage inequality. Taking this finding into account, we estimate the impacts of international trade, skilled-biased technological change and labor market conditions on within-sector wage inequality in Korea. Our estimation results suggest that there was a structural change in determinants of wage inequality before and after the mid-1990s. The influence of international trade mainly through heightened import competition on wage dispersion became relatively more conspicuous over the last two decades.     

A research on wage status and wage expectations of migrant workers in Hulan District

Since 2004, there has been the succession of migrant workers labor shortage all over the country. Among the factors causing farmers to hunt jobs in cities, wage plays a decisive role. So in this paper, it made an investigation and research on wages status and salary expectations of migrant workers in Hulan District. There are three main problems of migrant workers wages in Hulan District： The migrant workers＇ average wage is less than the community average wage; the wages were cut down in fact because of long working hours, as well as the low rate of return. In this district, the wage expectation of migrant workers on average is between 1341.8 and 1496.9 Yuan, that is 0.91-1.01 times as many as local minimum wage standard （after adding the overtime pay）; and 0.98-1.12 times as many as AVG salary last year. At last, it gives some suggestions： The enterprises should raise the standard of wages referring to the wage expectation of local migrant workers; local government should enhance skill trainings for migrant workers.     

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.     

Minimum wage,trade and unemployment in general equilibrium

The path‐breaking work of Card and Krueger, showing that a higher minimum wage can increase employment, turned the age‐old conventional wisdom on its head. This paper demonstrates that this apparently paradoxical result is perfectly plausible in a competitive general equilibrium production structure of a small open economy with a non‐traded good, without recourse to monopsony, spatial heterogeneity, heterogeneity of consumers and so on, the usual theoretical drivers behind the result. Following Jones and Marjit, we build a simple general equilibrium model with production complementarity and we show that a higher minimum wage can raise aggregate employment. Expansion in the non‐traded sector following a wage hike may be consistent with the overall expansion of the export sector in a multi‐good framework, an unlikely outcome in a conventional two‐good model which cannot accommodate with production complementarity.     

The effect of tariff reductions on firm size and firm turnover in canadian manufacturing

Using panel data on 81 Canadian manufacturing industries over the 1983–1996 period, the authors show that the estimated impact of recent tariff cuts was a positive and significant increase in the exit rate of firms. Supplementing this finding with recent research showing, that exiting firms tend to be less productive than those that survive, this provides support for recent trade models asserting that increased exposure to international trade induces the exit of least efficient firms, thereby contributing to productivity growth.

全球生产网络、贸易结构与工资差距：来自中国的证据

论文通过建立全球生产网络的中间投入品模型,实证分析中间品贸易对一国技术劳动力和非技术劳动力工资差异的影响。研究发现：加工贸易是中国融入全球生产网络的典型形态;其出口会扩大对技术和非技术劳动力的需求。但技术劳动力的工资上涨幅度要高于非技术劳动力的工资涨幅,从而使相对工资差距扩大。短期内,中间品的进口减少了技术劳动力的需求和就业,但长期来看中间品进口会扩大对技术劳动力的需求,相对工资差距拉大。人力资本投资的供给增长由于未能满足劳动力市场的需求,从而在一定程度上表现为工资差距拉大;但长期来看,人力资本积累机制的完善使得相对工资差距会逐渐缓和。     

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.

Wage Differentials in Taiwanese Manufacturing, 1982–1997

The present paper examines the impacts of technological change and trade flows on wage inequality across manufacturing industries. Using micro–level data from the Taiwan Manpower Utilization Survey (TMUS), 1982–1997, a slight decline in the log–wage differential between college and high–school workers is detected during this period. These results indicate that the accelerated growth in the relative supply of college graduates, combined with steady demand growth in favor of more highly educated workers, can largely explain the narrowing wage differentials within Taiwanese manufacturing over the period 1982–1997. In terms of demand–side factors, this study concludes that technology and trade are the two major forces driving the differences in wage inequality across industries.     

Parenthood penalty and gender wage gap: Recent evidence from Thailand

This study first examines the evolution of gender wage gap in Thailand, using cross-sectional data from the Labor Force Survey (LFS) for 1985–2017. We find that education, occupation, and industry significantly contribute to gender wage gap convergence in Thailand. Furthermore, for females, the wage gap between mothers and non-mothers has increased over time, while for males, the changes are relatively small. Thereafter, we examine the gender wage gap associated with marriage and parental status, using panel data from the Socio-Economic Survey (SES) for 2005–2012, and find wage penalty for both motherhood and fatherhood in Thailand.     

Global value chains,firms, and wage inequality: Evidence from China

How does participating or moving to more upstream in the global value chains (GVCs) affect the premium paid to skilled compared to unskilled labor within firms? In this paper, we develop a model of heterogeneous firms with intermediate trade and two skill inputs, in which we apply the fair wage hypothesis to predict the wage premium changes according to firms' GVCs activities. The model predicts that firms' backward GVC participation, as measured by the share of foreign value-added content in exports (FVAR), has an ambiguous impact on wage inequality of skills, which depends on the relative importance of “FVAR-labor substitution effect” and “FVAR-profit effect.” However, moving to upstream sectors in GVCs, as measured by the export varieties' upstreamness (or average distance from final use), raises a firm's wage premium. Using detailed Chinese firm-level data from 2000 to 2006, we develop a Mincer-type empirical model to study the wage premium changes associated with FVAR and upstreamness. We find robust empirical evidence that the rise of wage inequality in China mainly arises from moving to more upstream sectors rather than changing GVC participation.
