Trade Liberalization and Wage Inequality: Evidence from India

We evaluate empirically the impact of the dramatic 1991 trade liberalization in India on the industry wage structure. The empirical strategy uses variation in industry wage premiums and trade policy across industries and over time. In contrast to most earlier studies on developing countries, we find a strong, negative, and robust relationship between changes in trade policy and changes in industry wage premiums over time. The results are consistent with liberalization‐induced productivity increases at the firm level, which get passed on to industry wages. We also find that trade liberalization has led to decreased wage inequality between skilled and unskilled workers in India. This is consistent with the magnitude of tariff reductions being relatively larger in sectors with a higher proportion of unskilled workers.     

Statistical Discrimination and Gender Wage Gap: A Model

In this paper, I extend the model in Coate and Loury (CL) (1993) to show how statistical discrimination by employers can help create gender wage gap for men and women with equal earning potentials. Given that employers do not perfectly observe a worker’s skill type and partly rely on the average skills level of his (her) peers for inference purpose, employers’ differential treatment of male and female workers can create different skill-investment incentives for them, which in turn justify employers’ discrimination in the first place. The second result of this paper which is not possible within the original CL framework is that I point to the possibility that there exist circumstances under which the gender wage gap can not be eliminated without the formerly advantaged sex being negatively affected.     

职业分割、性别歧视与工资差距

文章通过"晒工费"网络平台提供的调查数据,利用Appleton分解方法对我国城镇职工的性别工资差距进行了分解.结果表明,受教育程度、工作年限等人力资本水平对男女工贵差异有显著的影响,而且我国劳动力市场上存在一定的职业性别分割.分解数据显示,职业内工资差异与职业闻工资差异分别为22.5%和15.7%,即存在比较严重的纵向和横向性别职业隔离.此外,分析结果还揭示了职业性别歧视是导致城市男女工资差异的主要原因.     

贸易开放与性别工资差距

本文在不完全竞争市场环境下,建立贸易开放和性别工资差距的数理模型。在理论分析的基础之上,本文运用2002年中国家庭住户收入项目调查数据(CHIP)进行实证分析。在控制了年龄、婚姻状况和受教育年限等个体层面和人均GDP等城市层面的工资影响因素情形下,得出结论:贸易开放在总体上拉大了性别工资差距;贸易开放缩小了高技能劳动力的性别工资差距,拉大了低技能劳动力的性别工资差距。从某种意义上说,女性弱势群体更容易被排除在贸易开放的利益之外。因此,提高女性的受教育程度,并为之提供相应的制度保障具有尤为重要的政策含义。     

Union Wage Strategies and International Trade

We characterise a full set of possible international trade regimes for different combinations of wages in a two-country model of oligopoly with a homogeneous product. We show that the nature of any equilibrium trade will be either inter-industry (one-way) or intra-industry (two-way) depending on (endogenous) union choices between high and low-wage strategies. We show that intra-industry trade is the more likely the lower are trade costs, and that under intra-industry trade, falling trade costs lead monopoly unions to set higher wages, but the opposite obtains under inter-industry trade.     

International Trade,Technology, and the Wage Gap: Evidence from Granger‐causality Tests*

In this paper, we propose an alternative approach under which to examine the source of the increased wage gap between skilled and unskilled workers in US manufacturing. Rather than imposing the assumptions inherent in a given structural form, we posit a long‐run equilibrium relationship between international trade, technology, and the wage premium using a vector error‐correction model. We first test for the existence of a long‐run relationship using cointegration tests. If a cointegrating relationship is found, we then conduct tests on the direction of the long‐run relationship and of Granger causality. We apply our approach to each two‐digit and four‐digit SIC industry and find evidence in support of international trade being an important source of the wage gap. Our results suggest that it is premature to dismiss international trade as a possible suspect behind the rising wage premium.     

Trade Liberalization and Gender Wage Inequality in Mexico

Abstract

After twenty years of trade liberalization in Mexico, the relationship between gender wage inequality and trade remains insufficiently studied, in spite of evidence of increasing numbers of women in industrial employment. This study aims to analyze the effects of export orientation and other characteristics that represent the industrial underpinnings of restructuring on gender wage inequality for 2001–5. There is consistent evidence of the negative impact of export orientation on men's and women's wages and the gender wage ratio, signifying that women lose in both absolute and relative terms. This result holds after controlling for women's share of employment and the skills of both genders, contrary to the expected effect from trade on equality. There is also a negative relation between a rise in the proportion of unskilled workers and the gender wage ratio, which suggests that the trade-induced skill hypothesis cannot be considered an adequate explanation for gender inequality.     

Trade Liberalization and Wage Inequality: Evidence from the U.S. States

This paper examines the relationship between trade liberalization and wage inequality for 50 U.S. states during the period from 1999 to 2008. The Difference-in-Differences and fixed effects methods are employed to evaluate the effect of trade liberalization on wage inequality in the U.S. states. Empirical results reveal that trade liberalization and de-unionization do increase the wage inequality between skilled and unskilled workers. Evidence shows skill-biased technological change has no significant impact on rising wage inequality. As Difference-in-Differences estimation on time-series cross sectional data involves many years, the conventional standard errors often understate the standard deviation of the estimators. This paper employs the standard bootstrapping procedure and the clustering error procedure to correct the problem, and all sign patterns still hold.     

Decomposing Gender Wage Differentials Using Quantile Regression: Evidence from the Lebanese Banking Sector

This paper investigates gender pay inequality in the labor market of a developing country. Our empirical investigation uses data derived from a sample of employees in the Lebanese banking sector for the years 2008 and 2014. Using Blinder-Oaxaca decomposition, the results reveal that the unexplained component of the gender wage gap, attributed to discrimination, represents a substantial share of the total gap. A surprising result is that the contribution of human capital to the gender wage gap is negative, suggesting that wage discrimination is the main explanation for the gap. Utilizing the Machado-Mata methodology to decompose the wage gap across the entire wage distribution, our findings indicate that the unexplained component of the raw gender wage gap is more pronounced at the low and middle ranges of the distribution. However, the explained component dominates at the top of the distribution, suggesting that earnings gaps are fully explained by observed characteristics.     

International Trade and Inter‐Industry Wage Structure in Swedish Manufacturing: Evidence from Matched Employer–Employee Data*

This study examines the inter‐industry wage structure in Swedish manufacturing, using matched employer–employee data for the period 1996 to 2000. First, we used detailed individual and job characteristics to estimate industry‐specific and time‐varying wage premiums. Secondly, we investigated the impact of international trade on wage premiums, controlling for effects of domestic competition and technical progress. Our results suggest that industries that face intensive import competition from low‐income countries have lower wage premiums. Surprisingly, the wage premiums are not related to export intensities. Furthermore, technical progress, measured by investment in R&D activity, appears to enhance inter‐industry wage premiums.     

Wage Discrimination in India's Informal Labor Markets: Exploring the Impact of Caste and Gender

Although there has been considerable interest in wage discrimination in India, available studies have largely dealt with formal rather than informal markets that are of little relevance for the poorest people. Focusing on India's informal labor markets leads to three findings of interest. First, gender wage discrimination is larger in informal than in formal labor markets, resulting in losses that are larger than receipts from one of the country's most important safety‐net programs. Second, economic growth will not make gender discrimination in wage labor markets disappear. Finally, contrary to what is found for gender, the hypothesis of no significant wage discrimination based on caste cannot be rejected.     

Trade patterns and institutional change in East Asia

We investigate how trade patterns – institutionally intensive exports (IIX) – affect institutional quality in East Asia compared to the rest of the world, and whether the effect changed due to the Asian financial crisis. To examine this, we use panel data of 117 countries for the period 1988–2007. Our fixed effect model estimation reveals that the effect of IIX on institutional quality is negative and significant for East Asia, while the effect is insignificant for the rest of the world. The negative effect in East Asia is more pronounced for the five East Asian countries that were strongly affected by the crisis – South Korea, Indonesia, Malaysia, the Philippines and Thailand – than for other East Asian countries. Furthermore, our results reveal that the negative effect for East Asia does not change significantly after the crisis, both in the short and long term, and that improvement in institutional quality after the crisis is not different from that of the rest of the world. This suggests that the crisis had no significant impact on East Asia's institutional quality or on the effects of IIX on institutional quality.     

Time-Series Wage Differential in Taiwan: The Role of International Trade

Rising relative wages between skilled and unskilled workers in developed countries has been a popular subject of recent studies. This paper analyzes Taiwan, a semi-developed economy, where the relative wage reveals a declining trend since the mid-1980s. The authors study the role of international trade. A major point of departure is to distinguish the effects of net exports to OECD countries from those to non-OECD countries. The paper also differentiates the effects of net exports to China from those to non-OECD countries except China. It is found that net exports to the OECD countries raise the relative wage of skilled workers, whereas net exports to non-OECD countries and China diminish the relative wage. Moreover, the impacts of net exports to China are much larger than those to OECD and other non-OECD countries. The documented wage effects of international trade in this work diverge from what existing works have argued based on Heckscher–Ohlin theory.     

Short-Term and Long-Term Margins of International Trade: Evidence from the Canada-Chile Free Trade Agreement

We investigate the impact of the Canada-Chile Free Trade Agreement (CCFTA) on Canadian exports to Chile, particularly the dynamic effects of the agreement on extensive and intensive margins of trade. Consistent with the literature, we find that the extensive margin effects occurred later than the intensive margin effects and became more prominent in the long-term. Surprisingly, the intensive margin effects died off in the long-term. A theoretical model is constructed to show that our results can arise in a standard setting of intra-industry trade.     

Monetary Integration in East Asia: Evidence from Real Effective Exchange Rates

This paper investigates the feasibility of forming a monetary union in East Asia by examining the cointegration and causality of the real effective exchange rates of local currencies. A “pentagon” group of five countries is found—South Korea, the Philippines, Thailand, Indonesia, and Malaysia—which may have potential for success for further monetary integration. Singapore is loosely tied to this group. The Greater China area—China, Hong Kong and Taiwan—does not show any significant degree of integration either internally or externally. Neither a yen bloc nor a US dollar bloc is forming in East Asia.     

贸易开放、劳动力流动与城镇劳动者性别工资差距——来自1992-2009年中国省际面板数据的经验证据

贸易开放给劳动力市场带来的经济后果是非常复杂的,而收入不平等就是其中一个重要方面.现有关于贸易开放影响收入不平等的文献大多着眼于总体收入不平等程度或技能工资差距,而对性别工资差距的关注则不多.文章利用1992-2009年国家统计局的城镇住户调查数据,系统地考察了贸易开放对不同部门、不同技能水平的城镇劳动者性别工资差距的影响.研究发现:(1)贸易开放对制造业的性别工资差距具有显著的正向影响;(2)分技能水平的分析结果显示,贸易开放对制造业中高技能劳动者的性别工资差距无显著影响,主要是拉大了低技能劳动者的性别工资差距;(3)贸易开放是通过影响劳动力流动和就业结构来影响性别工资差距的.因此,从保护女性的角度来说,政府应该通过提高女性的技能水平等政策措施来促进两性平等.     

市场歧视对城镇地区性别工资差距的影响

本文使用基于分位数回归的反事实分析方法研究了中国城镇地区的性别工资差距问题,发现了以下三个结论:第一,性别工资差距在工资分布不同位置上存在不对称现象。从横截面数据来看,在工资分布顶端性别工资差距较小,在工资分布末端性别工资差距较大。从时序数据来看,在工资分布顶端性别工资差距越来越小,在工资分布末端性别工资差距越来越大。第二,性别工资差距在横截面数据上表现出不对称现象的原因是,女性在工资分布顶端受到的歧视程度低,在末端受到的歧视程度高。第三,性别工资差距在工资分布末端越来越大的原因是,女性受到的歧视程度越来越高;在工资分布顶端越来越小的原因是,男性和女性个人特征方面(如受教育水平)的差别越来越小。     

Gender Wage Gap: Some Recent Evidences from India

Gender wage inequality is a chronic socioeconomic malice in developed as well as in developing countries. This paper describes the outcomes of our study on the estimation of gender wage gap in the Indian labour market, using the 68th Round NSSO employment–unemployment data. The study uses Blinder–Oaxaca decomposition technique and Heckman two-step methodology, for removal of selectivity bias in the sample data, to measure the components of total gender wage gap, viz. (1) occupational segregation (explained by economic rationale) and (2) direct discrimination (not explained by economic rationale). The analysis indicates that the maximum direct discrimination is for job-related factors, such as industry type which are controlled by employers. The majority of the Indian employers today are men, which may be the reason for the insensitivity to the chronic direct discrimination against women in workplaces. The study also indicates that most of the explained gender wage gap is due to lower skill and experience amongst women. The findings suggest that besides labour law reforms for ensuring gender neutrality in workplaces, focused government policies for promoting women entrepreneurship and skill development of women are urgently required for reducing the gender wage gap in India.

     

Trade Strategy, Investment and Exports: Another Look at East Asia

The export booms in South Korea and Taiwan starting in the early 1960s are anomalous when compared with later export booms in non-East Asian countries such as Chile and Turkey. First, these booms have taken place in the context of comparatively small changes in relative prices in favor of exportables. Second, they have been associated from the start with booms in investment. This paper offers evidence and a formal model to suggest that exports in East Asia may have been driven by an increase in the profitability of investment, with outward orientation a consequence of the investment boom rather than its instigator.
