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.     

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.     

Industrialization and wage inequality in nineteenth-century urban America

What happened to wage inequality during American industrialization? This paper uses old and new data to address this question. The old data are in the form of pay ratios, while the new capture changes in the overall wage distribution, rather than in just the relative pay of workers at the top and bottom. Using payroll information from the Aldrich report for establishments in construction, railroads, and manufacturing, we calculate Theil indices for all production workers. These two data sets provide complementary information but suggest a common conclusion — namely that American wage inequality did not rise perceptibly over the nineteenth century.     

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.     

Appropriation,firm dynamics,and wage inequality

This paper examines the income distribution and welfare effects of appropriation activities in an economy. In the short run, with a given number of firms, appropriation can narrow wage inequality between skilled and unskilled labor when the capital resources accrued by appropriators are not large. However, wage inequality widens when the capital accrued is large. In the long run, with free entry and exit of firms, an increase in appropriation can cause firms to enter when the accrued capital is not large. This gives rise to a win–win outcome by raising the wages of skilled and unskilled labor. However, if accrued capital is large, firms exit and a lose–lose situation may occur in which skilled and unskilled wages are reduced.     

Trade and wage inequality: Are they related?

The objective of this paper is to investigate the relationship between net exports and wage inequality in the U.S. The short- and long-run analyses of the U.S. trade and wage data are undertaken. Cointegration test results indicate that net exports and wage inequality are related in the long run. The main contribution of this paper lies in its focus on the short-run investigation of the relationship between net exports and wage inequality. This investigation was conducted using the vector error correction (VEC) testing framework. Contrary to the prevailing view, the VEC test results indicate that trade has no statistically significant impact on wage inequality in the U.S. Instead, the empirical evidence shows a negative causal impact of wage inequality on net exports.     

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.     

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.     

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.     

Hukou and Graduates’ Job Search in China*

This paper presents evidence that graduates from rural areas, classified as non‐urban Hukou, choose to invest in higher levels of job‐search effort (as measured by number of different search methods used and the number of employers contacted) and also set a lower reservation wage, reflected in acceptance of a lower starting salary, than do comparable graduates of urban Hukou, in China. The former also appear to have higher probabilities of being employed, in terms of both their higher probabilities of receiving offers and, more importantly, their higher probabilities of acceptance. The evidence thus suggests that graduates with non‐urban Hukou face more intense pressure to gain employment in the period leading up to graduation, than do their urban counterparts. More generally, the evidence suggests that effort invested in job search is rewarded in the graduate labor market in China.     

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.     

Scale-independent North-South trade effects on the technological-knowledge bias and on wage inequality

This paper develops a general equilibrium endogenous growth model that highlights the scale-independent mechanisms through which trade-induced North-South technological-knowledge diffusion affects the technological-knowledge bias and, thus, the paths of intra-country wage inequality. In contrast with the market-size effect, stressed in the previous literature on skill-biased technological change, the operation of the emphasized price channel following openness predicts, in line with the recent trends in developed and developing countries, an increasing skilled technological-knowledge bias, which, in turn, rises wage inequality in favor of skilled labor.     

Automation and inequality in China

In transitional economies, low wages imply sub-OECD yet growing labor shares of value added. China's rapid development has, however, seen a declining low-skill labor share and rising inequality. Here, a stylized model with three households and separable TFP and factor bias suggests a third of the decline in the low-skill share since 1994 is due to structural change and the rest mainly to skill-biased technical change. Expected future twists away from low-skill labor toward capital yield further inequality, moderated if strong TFP growth and population stability continue. But if the bias accompanies TFP shortfalls, worker displacement and rising inequality are in prospect.     

Multinational companies and wage inequality in the host country: The case of Ireland

Multinational Companies and Wage Inequality in the Host Country: The Case of Ireland. — In this paper, the authors analyze the impact of multinational companies on wage inequality in a host country. Based on a model, in which the introduction of new technologies leads to increases in the demand for skilled labour and, therefore, to rising wage inequality, they econometrically study the Irish manufacturing sector between 1979 and 1995. They examine inequality between wages for skilled and unskilled labour within the same manufacturing sector. Their results indicate that there is an inverted-U relationship between wage inequality and multinationals, i.e., with the increasing presence of multinationals, wage inequality first increases, reaches a maximum, and decreases eventually.     

Pollution mitigation,unemployment rate and wage inequality in the presence of agricultural pollution

This paper established a small open general equilibrium model to investigate the effects of the changes of consumers' unit private mitigation expenditure on the unemployment rate and the urban-rural wage inequality etc.. We found that (1) in the capital specific case, the increase of unit private mitigation expenditure will not only increase the urban unemployment rate but also expend the urban-rural wage inequality; (2) in the capital movable case, the conclusions are exactly opposite to that of the capital specific case. And under certain conditions, the increase of unit private mitigation expenditure may improve national income. According to the parameter calibration and numerical simulation results of the relevant macroeconomic data of China in 2017, we also found that (3) the effects of the changes of unit private mitigation expenditure on the urban unemployment rate is greater than that of the urban-rural wage inequality; (4) the influence degree of the changes of unit private mitigation expenditure on the unemployment rate in the capital movable case is greater than that of the capital specific case, but the influence degree of the change of unit private mitigation expenditure on the urban-rural wage inequality in the capital movable case is smaller than that of the capital specific case.     

Market reforms and consumption puzzles in China

China exhibits above average savings and below average consumption as shares of total economic activity when compared with other countries. At the same time, to create more balanced growth at home and rebalance key bilateral trade and capital flow relationships, China's leadership is trying to increase domestic demand. To complement studies that investigate the high rate of savings in China, this study focuses on the variation in consumption as a share of GDP across provinces between 1979 and 2004. Drawing on well-established consumption theories and work done on savings behavior in China, this paper develops an empirical investigation of the variables hypothesized to influence the pattern of consumption across regions.We find that the normal, economic variables have a small explanatory power if significant at all, while the key variables influencing the macro consumption share are structural, and mostly related to government behavior. For example, local government expenditure on health and education is significant and has a relatively large effect on consumption. Consistent with this we also find a positive relationship between consumption shares and the size of the state sector and the share of tax revenue in GDP. We also find some evidence that financial development has a positive effect on consumption shares. Our results suggest that in order for domestic consumption to be increased in the future, new public and private options to replace the declining security and responsibility of the prior state-dominated system will be needed.     

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.     

Geography and educational inequality in China

Since the 1980s, educational reforms in China have decentralized administration and finance and privatized costs. These changes have emerged in the context of rapid economic growth and rising regional economic disparities. The reforms have mobilized new resources in support of education, but they have also exacerbated regional disparities in funding for schools. Analyses of trends in school finance and expenditures have emerged, but detailed studies of the shifting ties between geography and educational outcomes in the population have not.Using 2000 census data on year and location of birth and educational attainment, we begin to address this gap. We compare the links between birth province and educational outcomes across 5-year birth cohorts to illuminate trends in region-based inequalities. Results show that the percent of variation in years of schooling explained by birth province declined for cohorts born through the early 1960s, and then increased thereafter.Additional analyses use a dissimilarity index to characterize the strength of the link between geography and access to each level of schooling. This index indicates that the link between geography and access to primary school has greatly increased across cohorts, as the few without access to primary school are ever more concentrated in poor areas. The link between birth province and access to subsequent levels of schooling shows mixed trends through cohorts born in the early 1960s: stability for junior high school and a weakening trend for senior high school and college. Thereafter, the dissimilarity index increased, substantially for junior high school and slightly for senior high school and college.Results attest to the enduring significance of geography as an educational stratifier in China. More broadly, results suggest the importance of regional inequalities in conditioning the relationship between development and educational stratification.     

Hukou status,housing tenure choice and wealth accumulation in urban China

In Chinese cities, migrants with rural hukou, compared to residents with local urban hukou, face more uncertainty, have limited access to mortgage finance, and are less eligible for low-cost housing. A simple model demonstrates that for these reasons, rural-to-urban migrants are less likely to own housing units in cities and as a result accumulate less wealth. Our empirical analysis examines a nationally representative household survey from 2013 and uses mother's hukou status as an instrumental variable. We find that household heads with rural hukou are about 20 percentage points less likely to own housing units in cities than comparable household heads with local urban hukou. Consequently, the average household head with a rural hukou owns 315 thousand yuan less housing wealth and 226 thousand yuan less total wealth than comparable household heads with local urban hukou. The average household head with a rural hukou has 288 thousand yuan less in housing capital gains than comparable household heads with local urban hukou. Moreover, we find that these differences are much larger in the first- and second-tier cities, cities with more stringent hukou regulations, and among younger cohorts.
