Why is the gender earnings gap greater in Korea than in the United States?

It has long been recognized that the gender earnings gap varies across countries. This paper examines the relatively higher gender earnings gap found in the Korean labor market compared to the US labor market. Using the data set representative of the population for both countries, I found that the significant part of the differences in the gender earnings gap simply arise from the differences in the observed characteristics of women among two countries. In particular, relatively lower labor market experience, current job tenure, and educational attainment by Korean female workers play dominant roles in explaining the observed higher earnings gap. In addition, wage structure and labor market discrimination seem to be against Korean female workers compared to US female workers. J. Japanese Int. Economies 21 (4) (2007) 455–469.     

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 vs. industry subsidies: coping with technology related unemployment in a globalized economy

In the past, economic policy has largely adopted a sectoral approach to technology-related unemployment. More recently though, wage subsidies have gained attention as an alternative means of reemployment, with the dispute on how best to cope with unemployment still unsettled. However, despite the fact that results may differ, research mostly assumed a closed-economy setting. Based on a HOS model with factor-augmenting technical change and labor-market rigidities, the paper examines the differences of these two subsidization schemes on output and employment. Since both schemes work through different channels, namely the demand versus the supply side, effects differ not only in magnitude. The paper includes a comparative calibration exercise for the case of Germany.

Wage and employment effects in the EU of international trade with the emerging economies

The paper investigates whether significant HOS effects are present in the EU from trade liberalization with the emerging economies. Regarding wage inequality, there is only evidence of a trade-induced technological change, but biased towards thelower-skilled-labor-intensive sectors. Relative wages in the EU member states are not affected differently. Trade liberalization under ‘European assumptions’, however, could affect primarily relative factor demand. A flexible cost function approach shows that import competition from the emerging economies influenced relative labor demand in favor of the higher skilled, implying an intrasectoral rather than an intersectoral specialization in skill-intensive activities.

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.     

Changing labor-force gender composition and male-female income diversity in Singapore

This paper traces the employment trends by gender in various industries, occupational groups, and educational levels in the city-state of Singapore. Over the years, Singapore’s female labor-force participation rate has increased as a result of rising educational attainment. At the same time, income inequality among the females has increased, while male-female income inequality has decreased. This paper explores the gender wage gap at various occupational and educational levels. It is found that the gender wage gap has been reduced over the period 1975–1999. This paper also finds that because of a lack of sufficient childcare facilities and unavailability of part-time work, women who leave the labor market to start families face certain obstacles when trying to re-enter the workforce.     

Jobs with different wage determination mechanisms, social efficiency and unemployment

The purpose of this paper is to construct a theoretical framework for the labor market, which is composed of a variety of jobs with different wage determination mechanisms. We identify an equilibrium in which some firms post a wage and others bargain with workers. This paper shows that the proportion of firms adopting wage bargaining in a decentralized equilibrium is below the socially optimal level. We identify policies to increase this proportion and to improve social efficiency. Furthermore, we examine the impact of those policies on unemployment. The results of this study will determine the direction of employment policy on the labor market with various employment styles.     

The rise and fall of the sliding scale, or why wages are no longer indexed to product prices

Though almost no postwar union contracts indexed wage rates to prices of the employer’s products, union agreements linking wage rates to product prices, known as sliding scales, were common in some industries in the United States and Britain from the 1860s through the 1930s. This paper explains why sliding scales disappeared after the 1930s, and examines what practical experience with sliding scales revealed about fundamental constraints on wage indexation. Paradoxically, the history of sliding scales confirms that workers’ information about product prices and materials costs is generally imperfect, in ways that would substantially constrain wage indexation in long-term contracts. Sliding scales were not indexed long-term contracts, but rather devices to forestall costly strikes in the absence of contracts by revealing employers’ private information about product demand. In the postwar US, unions and employers failed to link wage rates to product prices because they had gained the ability to enter binding contracts, which could achieve the benefits of preventing strikes without incurring the extra negotiation costs and information problems associated with product-price indexation. I present a model to show how sliding scales could forestall strikes by revealing information, and how the introduction of binding union contracts reduced incentives to link wages to product prices.     

Wage dispersion in Germany and the US: is there compression from below?

Wage compression from below is a common diagnosis for Germany compared to the U.S. We develop alternative hypotheses in order to identify the so-called accordion effect, i.e. reduced inter-quantile distances below the median especially for low skilled and other ill-paid groups. Our results are partly at odds with wide-spread beliefs. Using large micro data sources we find evidence of an accordion effect at the low end of the distribution for the U.S. The results for Germany, however, are contrary to what one would have expected in case of marked wage compression from below. For low-skilled workers of both genders and for female workers in general we find higher inter-quantile distances below rather than above the median. By contrast, there is strong evidence for the accordion effect if skilled male workers are considered.     

市场化进程、企业绩效与高管过度隐性私有收益

制度环境是影响我国高管薪酬契约发挥激励作用的重要因素,本文以市场化进程为背景,检验企业绩效与高管过度隐性私有收益之间的关系,并探究市场化进程对上述关系的影响。研究发现：由于我国上市公司高管隐性薪酬契约普遍缺乏有效设计和监督,企业上期绩效与本期高管过度隐性私有收益负相关;随着市场化进程深入,民营企业绩效与高管过度隐性私有收益之间的负相关关系显著缓解,并且当民营企业高管权力较大时,市场化进程能够更加有效地抑制企业绩效与高管过度隐性私有收益之间的负相关关系,但是上述关系在国有企业中并未得到有效改善。进一步检验发现,市场化改革促使企业绩效和高管现金薪酬之间的相关性不断提高。本文的研究结果有助于揭示市场力量在提高高管薪酬契约激励有效性时发挥的作用及遇到的困难,为抑制国企高管过度隐性私有收益提供合理建议。     

Wage increases, wage convergence, and the Lewis turning point in China

We examine the wage trends of ordinary workers and the wage convergence between unskilled and skilled workers in China. First, we find that wages in all non-agricultural sectors, wages of migrant workers, and wages of hired workers in the agricultural sector have increased dramatically since 2003. Second, through comparing wage differentials between migrant and urban resident workers and between heterogeneous education groups within migrant workers, and by investigating the changes in the contribution of the returns to education to wage differentials, we find that the wages of unskilled and skilled workers have converged. Both the increasing wage trends and wage convergence are interpreted as evidence supporting the hypothesis that China has passed what can be called the Lewis turning point in the industrial sector. We conclude that the sustainability of economic growth in China requires an upgrading of labor market institutions to accommodate the merging of the rural and urban labor forces.     

The Chinese State Enterprise Sector: Labour Market Reform and the Impact on Male–Female Wage Structure

The paper examines the wage structure in the Chinese state enterprise sector between 1981 and 1987. This period is of particular interest given the introduction of major labour market reforms in China during the early 1980s. In essence the reforms represented a movement away from administratively determined prices towards a market–oriented system combined with a relatively flexible system of labour allocation. The Juhn, Murphy and Pierce (1991) decomposition is employed to shed light on the role of changing labour market institutions over the period.

Smoking and wage rates – Evidence from Japanese panel data

This paper analyzes smoking behavior and its effects on wage rate. It is widely known that smoking has negative health effects and to discourage the practice, governments frequently implement policies such as tax increases and restrictions on public smoking. To evaluate these policies, it is necessary to understand the economic benefits and costs of reducing the number of smokers. We conduct a panel data analysis while controlling for unobserved heterogeneity and show that smoking is not the main factor causing observed wage differentials between smokers and non-smokers in Japan.As for the relationship between smoking and wages, we find that male smokers receive lower hourly wages than male nonsmokers. Smoking behavior generally depends on environmental, congenital, or social factors. These factors, however, do not only affect smoking behavior but also the wages of these individuals. To isolate the effect of smoking on wages, we control for individual heterogeneity using panel data to verify the existence of such an effect.Using tax change as an instrumental variable in the fixed effects model and several robustness checks, the results show that smoking has no statistically significant effect on wage rate. This suggests that smoking does not directly affect wages; rather, unobserved individual heterogeneity (other factors influencing both smoking and wages) leads to wage differences between smokers and nonsmokers. Nevertheless, smoking can affect wages in the long run through health problems. The nine-year panel data used in this research, however, is insufficient to capture the long-term indirect health effects. Thus, future research should consider analyzing indirect health effects using panel data spread across a wider time frame.
