Urban bias and wage inequality

This paper explores how urban bias affects skilled–unskilled wage inequality through building several general equilibrium models. In the basic model, we find that an increase in the degree of urban bias will widen wage inequality if the unskilled sector is more capital intensive than the skilled sector and reduce wage inequality if the skilled sector is more capital intensive than the unskilled sector. In the extended models, we find that the conclusion obtained in the basic model almost still holds under different conditions.     

Organized crime and wage inequality

This paper stresses the role of industrial organization of crime, and explores how organized crime affects wage inequality. We find that, when only unskilled workers (or both skilled and unskilled workers) engage in organized crime, an increase in the number of criminal groups will increase wage inequality if (1) the skilled sector is more capital intensive than the unskilled sector, and (2) the price elasticity of demand for the skilled product is large enough. However, when there are only skilled workers engaging in organized crime, condition (1) is sufficient to widen wage inequality, irrespective of the price elasticity.     

China wage inequality: the role of trade and technology

This article empirically investigates the impact of international trade and technical change on skill premia for a panel of 28 manufacturing sectors in China over the period 2002–2011. The results find that the effect of changes of the share of SOEs is twofold. First, the contraction of SOEs promoted productivity growth, and the promoting effect was skill-biased, which tended to increase the skill premia in China. Second, the drop of product prices resulting from falling SOEs share was more magnificent in skill-intensive industries, which helped to mitigate wage inequality through product prices. The accounted-for portion of price changes by productivity growth was skill-biased, significantly raising skill premia through product prices. However, the portion of price changes accounted for by foreign price was unskill-biased, and world price competition diminished the growing income disparity in China.     

Financial structure in the age of globalization

Using a large panel data set covering 160 countries over the period 1990 to 2010, this article aims to address the question of how financial structure (bank-based versus market-based system) changes when economies are liberalized and opened to international capital markets. Specifically, in this study, globalization is characterized not only by trade and financial integration but also by other important aspects, such as social globalization, political globalization and cultural globalization. The empirical results support the impacts of globalization on financial structure, which are, however, diverse and strongly depend on the way to measure globalization and financial structure. Our finding also reveals a significant change in financial structure after the globalization process, except the case of low-income countries, in which financial structure seems to be not correlated with either globalization process or other macroeconomic variables.     

Minimum wages and the wage distribution in Estonia

Abstract: This article studies how changes in the statutory minimum wage have affected the wage distribution in Estonia, a post-transition country with little collective bargaining and relatively large wage inequality. The analyses show that the minimum wage has had substantial spillover effects on wages in the lower tail of the distribution; the effects are most pronounced up to the twentieth percentile and then decline markedly. The minimum wage has contributed to lower wage inequality and this has particularly benefitted low-wage segments of the labour market such as women and the elderly. Interestingly, the importance of the minimum wage for the wage distribution was smaller during the global financial crisis than before or after the crisis.     

Increased sorting and wage inequality in the Czech Republic

This paper makes use of a linked employer–employee dataset to examine the evolution of wage inequality in the Czech Republic during 1998–2006. We find evidence of slightly increasing returns to human capital and diminishing gender inequality and document sharp increases in both within‐firm and between‐firm inequality. We investigate several hypotheses to explain these patterns: increased domestic and international competition, decentralized wage bargaining, skill‐biased technological change and a changing educational composition of the workforce. Domestic competition is found to lower within‐firm inequality whereas we find no evidence that increased international trade at the industry level is associated with higher between‐ or within‐firm wage inequality. The key factors driving the observed increase in wage inequality are increased educational sorting and the inflow of foreign firms to the Czech Republic.     

Increasing urban wage inequality in China

Two strictly comparable cross‐section household datasets, relating to 1988 and 1995, are used to analyse the increase in wage inequality from an initially low level in urban China over this period of labour market reform. The institutional background and the evolution of policy are described. The rapid growth of wage inequality and the sharp widening of wage structure are quantified. Earnings functions are compared, and the increase in both the level and the inequality of wages are decomposed into their constituent elements. Quantile regression analysis is conducted to throw light on the relationships between the observed and the unobserved determinants of wages. Distinctions are made between the variables likely to represent human capital, discrimination, and segmentation. The evidence suggests that productive characteristics were increasingly rewarded as marketization occurred, but that discrimination and segmentation also grew. The move towards a fully‐fledged labour market was by no means complete.     

Decomposition and wage inequality

Earning differentials are investigated by a quantile regressions based decomposition, which disentangles the inequalities linked to the covariates and coefficients at various quantiles. Gender and region are considered the main sources of inequality. The unexplained gender and regional differences decrease at the highest wages. Their combination at the lower wages’ level affects women more, causing a so-called sticky floor. Gender and regional covariate effects show a prevalence of women covariates compared with the men’s group, and a prevalence of southern women covariates within the women’s group, particularly at the higher quantiles. This can be interpreted as a glass ceiling hindering southern women at higher wages.     

Efficient taxation, wage bargaining and policy coordination

This paper is related to the literature on optimal nonlinear taxation under right-to-manage wage formation, and we assume that the fall-back profit facing firms during wage bargaining depends on the profit they can obtain if moving production abroad. The purpose is to study how policy coordination among countries can be used to increase the welfare level in comparison with an uncoordinated equilibrium. We consider coordinated policy reforms with respect to the marginal taxation of labor income, the unemployment benefit and the provision of a public good. The results show that policy coordination that leads to fewer hours of work per employee and/or a reduction of the unemployment benefit will increase welfare compared to the uncoordinated equilibrium.     

The impact of the informal economy on R&D,wage inequality and economic growth

We extend the existing research and development (R&D) growth literature by focusing on the short–medium–long run effects of the informal sector on R&D intensity, wage inequality and economic growth, and by considering 18 OECD countries between 1990 and 2008. We show that: the steady state is unique and stable; the share of informal economy (IE) in production affects negatively R&D intensity and wage equality; Nordic countries have the lowest share of IE in production, while Mediterranean countries have the highest share of IE, wage inequality and R&D intensity but R&D spillovers are lower.     

Long-run impact of increased wage pressure

An unanticipated permanent increase in wage pressure is analyzed in a dynamic general-equilibrium model combining standard theory of capital accumulation and monopolistic wage setting. The long-run (steady-state) implications are identical percentage reduction in employment, consumption, and capital stock whereas wages and the real interest rate are unchanged. The reduction in employment on impact is larger than the steady-state reduction whereas wages rise and the real interest rate declines on impact.     

Green technological progress,agricultural modernization,and wage inequality: Lessons from China

Green technological progress (GTP) is crucial for environmental protection and economic growth in China. Over the past decades, China made huge GTP which exerts a far-reaching consequence on economic and social development. However, a paucity of research investigates the distributional effect of GTP. Meanwhile, we incorporate agricultural producer service sector into a three-sector general equilibrium model to reflect the modernization of small-scale agriculture. The agricultural producer service sector that acts as an intermediate sector can facilitate the utilization of intermediate inputs indirectly. To desalinate this process, a two-layer vertical production structure is established: parts of manufacturing goods are utilized by the service sector, outputs of which are intermediate inputs that could substitute labor in agriculture. Theoretical analysis shows that GTP increases both wage of skilled labor and unskilled labor. Nevertheless, GTP generates a greater impact on the wage of skilled labor than unskilled labor, leading to widening income disparity. Then, we examine the impact of GTP on wage inequality using a balanced panel data covering 30 provincial units in China during 2000–2019. In line with our theoretical conjecture, we find strong supportive evidences that GTP significantly widens the wage inequality.     

金融全球化与中国金融安全

在经济全球化的过程中，金融全球化是其发展的主要内容和高级阶段。金融的全球化会为经济的进一步发展创造更优越的金融条件，但与此同时也必然会带来金融风险的变化。金融全球化对世界经济和国别经济产生了深刻的影响，对国家金融安全的影响同样深刻，使国家金融安全问题更为突出。鉴于我国目前在金融安全领域存在的问题及国际上的经验教训，我国在制定发展战略、融入全球化浪潮时，对金融安全问题必须超前研究对策，做到趋利避害。     

Income inequality and financial reform in Asia: the role of human capital

We investigate whether financial reform can reduce income inequality in Asia, with particular emphasis on the role of human capital. Extending Galor and Zeira (1993), we demonstrate that financial reform is effective in reducing income inequality, and the effect is more profound in a country with higher human capital. Using the data for 18 countries in Asia, the region with the most promising financial reform, we confirm our theoretical finding. In addition, among disaggregated financial reforms, lift of credit control, better banking supervision and security market development seem to be significantly associated with reduction of income inequality.     

The contribution of minimum wage valorization policy to the decline in household income inequality in Brazil: A decomposition approach

There is a vast literature that estimates the effect of the minimum wage on wage inequality in various countries. However, as the minimum wage directly affects nonlabor income of families in some countries (in the Brazilian case via the benefits of the pension system and of certain social programs), this article extends the empirical analysis by studying the effects of the minimum wage on the level of inequality of household income as a whole. To accomplish that we employ a decomposition method that gauges the contribution of the increases in the minimum wage that occurred in recent decades in Brazil through the labor and nonlabor sources of household income. The results show that the minimum wage had a contribution of 64 percent to the observed fall in income inequality between 1995 and 2014 and that pensions were the most relevant channel over this period.     

Explaining the increase in inequality during transition

This paper attempts to explain the increase in inequality that has been observed in all transition economies by constructing a simple model of change in composition of employment during the transition. The change consists of the 'hollowing-out' of the state-sector middle class as it moves into either the 'rich' private sector or the 'poor' unemployed sector. The predictions of the model are contrasted with the empirical evidence from annual household income surveys from six transition economies (Bulgaria, Hungary, Latvia, Poland, Russia and Slovenia) over the period 1987-95. We find that the most important factor driving overall inequality upwards was increased inequality of wage distribution. The non-wage private sector contributed strongly to inequality only in Latvia and Russia. Pensions, paradoxically, also pushed inequality up in Central Europe, while non-pension social transfers were too small everywhere and too poorly focussed to make much difference.     

The Polish wage inequality explosion1

This paper presents and analyses the sharp increase in hourly wage inequality after 1998 in Poland. The increase was similar in magnitude to the much‐studied increase in British wage inequality during the 1980s. Using data from the Polish Labour Force Survey, we find this increase to be associated with rising wage differentials and within‐group variances at both the upper and lower ends of the wage distribution. These increases are associated with differences in wage‐setting patterns between the public and private sector as well as with the rapid increase in demand for educated labour. One important difference between the sectors is the lack of an impact of local labour market conditions, or wage curve, clearly evident in private sector wages, on public sector wages.     

Downsizing, wage inequality and welfare in a developing economy

This paper focuses on the cost cutting effects of firm downsizing in a developing economy. Using a dualistic production structure to depict a developing economy, the impacts of downsizing on wage inequality and social welfare are examined. Downsizing is revealed to not only narrow the wage gap between skilled and unskilled labor but also to raise the level of manufactured output and reduce the unemployment ratio in the urban sector. These effects improve the social welfare of the economy.     

The Vietnam reforms,change in wage inequality and the role of the minimum wage

The Vietnam ‘renovation’ reforms were implemented during the 1990s, but their full effect was only felt several years later. We present evidence on the developments in real wage growth and inequality in Vietnam from 1998 to 2008. Using a variety of approaches (traditional measures of inequality, comparison of density functions, decomposition of the change in real wage by sector as well as a detailed decomposition of the change in the Gini), we present a consistent picture: contrary to what one might have expected given the nature of the reforms, inequality declined sharply in the private sector (but not in the state sector). This study links these developments to the policy of aggressively increasing the minimum wage over the past several years, differences in implementation by sector as well as variation in the over‐time changes in minimum wage.
