Long-run costs of piecemeal reform: Wage inequality and returns to education in Vietnam

In this paper, we examine changes in wage structure and wage premia during Vietnam’s transition from command to market economy. Relative to other work in this literature, our paper is unique in that we identify the policies that lead to such changes. By examining skill premium trends along the two dimensions of particular importance to the transition—state or non-state firms, and traded or non-traded industries—we are able to separate the contribution of external liberalization to wage growth and rising skill premia from that of domestic labor market reforms, and to examine potential interactions between the two types of reform. The results point to the high cost of incomplete reform in Vietnam. Capital market segmentation creates a two-track market for skills, in which state sector workers earn high salaries while non-state workers face lower demand and lower compensation. Growth is reduced directly by diminished allocative efficiency and reduced incentives to acquire education, and indirectly by higher wage inequality and rents for workers with access to state jobs.     

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.     

International knowledge spillovers and wage inequality in developing countries

In this paper, international knowledge spillovers are incorporated in a horizontal innovation model, designed to explain the observed uncertain effects that openness of trade can have on wage inequality in small developing countries. Openness of trade can produce two different effects: an increase in the relative price of less-skilled labor-intensive products and a wider skill discrepancy due to knowledge spillovers from the more to less developed country. The former triggers a fall in the wage premium, while the latter widens the wage premium gap in a developing country. These two opposing forces explain the observed uncertain effects of openness to trade on wage inequality in developing countries.     

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.     

Spillover effects of a minimum wage increase – evidence from Slovenia

This article Analysis the effects of a large increase in Slovenia’s minimum wage in March 2010 on the wage distribution using an administrative matched employer–employee panel database. We find that the minimum wage hike increased the concentration of low-paid workers, creating a much more pronounced spike at the minimum, particularly in market services, and for the young, the least educated and those with the least work experience. Our analysis also shows that the March 2010 minimum wage increase also produced sizeable spillover effects. The spillover effects were higher among young and older workers, especially for wage levels near the new minimum wage. The results are based on a difference-in-differences approach comparing changes in wages during the control and treatment periods as experienced by workers in the wage group immediately above the level of the new minimum wage and workers in wage groups higher up in the wage distribution.     

The evolution of the returns to education and wage differentials in Brazil: a quantile approach

This paper uses quantile regression techniques to analyze the returns to education across the conditional distribution of wages from individuals separated both by gender and skin color, while accounting for the endogeneity of the education decisions. Using data from the Brazilian households survey (PNAD) for the years of 1988 and 1996, the results indicate that the returns to education are significantly heterogeneous across the distribution of earnings, as well as the wage gap between the groups, according to gender and skin color. Moreover, there has been a significant improvement in the wage differentials between the groups across the years.     

The returns to education and wage penalty from overeducation: New evidence from Vietnam

This study intends to estimate the rate of returns to education in Vietnam, the distributive effects of education on wages, and the wage penalty from the incidence of overeducation in the Vietnamese labor market during 2004–2016. This study employs a pseudo-panel approach to address omitted variables bias and the unconditional quantile regression to identify the heterogeneity of returns to education across the income distribution. Our main finding indicates that the estimated rate of returns to education in Vietnam is approximately 6.5%, showing a downward bias from previous estimates. The returns vary across wage distributions, where a lower rate of return is observed in lower quantiles and a higher rate among those individuals at the higher quantiles. The returns to education have declined since 2008, confirming the oversupply of highly educated workers in the Vietnamese labor market with an estimated wage penalty of 17%. Government assistance measures are needed to reduce the overeducation and the wage penalty issues in the Vietnamese labor market.     

Anti‐immigration policy in the destination country and skilled–unskilled wage inequality in a source economy with or without unemployment

This paper is aimed at theoretically examining the consequence of the anti‐immigration policy adopted in the destination country on the skilled–unskilled wage inequality in a source nation using a couple of two‐sector, specific‐factor general equilibrium models in both the presence and absence of unemployment. Emigration requires incurring some capital cost for professional skill formation on the part of every prospective emigrant that adds to the opportunity cost of emigration. The authority of the destination country determines the number of visas to be granted and hence directly controls the magnitude of skilled emigration from the source country. In the migration equilibrium, the expected skilled wage income abroad is equal to the opportunity cost of emigration. In both the presence and absence of unemployment of unskilled labor, the outcome of the policy on the wage inequality crucially hinges on both the magnitude of the fixed cost of emigration and the technological factors. In the specific‐factor Harris–Todaro model, the degree of imperfection in the unskilled labor market is an additional factor. Finally, some policy recommendations have been made for protecting the interest of the poor unskilled workforce.     

Wage inequality and between-firm wage dispersion in the 1990s: A comparison of rural and urban enterprises in China

Using a worker–firm matched sample, this paper compares the changes of wage structures of urban and rural enterprises following public sector restructuring in China's manufacturing sector. While the wage responses of rural firms with respect to firm characteristics are found to have declined steadily, compensation of urban workers has become increasingly linked to their firms' ability to pay. Our analysis reveals that industrial restructuring has weakened the influence of institutional factors, such as market power, soft budget constraints, and insider influence, on the wage determination of rural firms but it has enhanced their impact on urban firms.

Wage settlements and wage setting: results from a multi-level model

Which dimensions of wage setting differ across establishments applying collective contracts and uncovered establishments? The empirical analysis reported here utilizes German linked employer–employee data for the years 1990, 1995 and 2001 and is restricted to workers without supervisory functions in larger manufacturing firms. Results show that the expected wage of an average worker is higher in firms applying collective contracts, while returns to human capital and the gender wage gap are reduced. Moreover, during the 1990s these effects became stronger.     

Wage determination and returns to education in different ownerships of China: Evidence from quantile regressions

In this paper, quantile regressions is used to estimate wage equations of different ownerships. Quantile regressions give us distributions rather than a single estimate of the returns both to education and experience in each ownership sector. For state-owned enterprises (SOE), the returns to education tended to be larger at the bottom of the conditional distribution of wages in 1991 and 1993, and there was no such trend in 1997. For the private sector, however, the returns to education tended to be larger at the top positions in 1993 and 1997. It is also found that the growth rates of the wages at the bottom of the conditional distribution of wages are higher than those at the top in SOEs. No such patterns for the private sector is found. It is suggested the wage mechanism in the private sector is more market-oriented. __________ Translated from Shijie Jingji Wenhui 世界经济文汇 (World Economic Papers), 2006, (4): 1–26     

Wage inequality and skill supplies in a globalised world

We investigate empirically, and explain theoretically, how the relative wages of skilled and unskilled workers vary with their relative supplies in open economies. Our results combine the insights of simple labour market and trade models. In countries that trade, relative wages respond inversely to variation in skill supplies, but the response decreases with the degree of openness to trade and is small in very open countries. To reconcile our results with standard estimates of the elasticity of substitution between skilled and unskilled workers, we allow also for the influence of directed technical change and income elasticity of demand for skill-intensive goods.     

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.     

Changes in wage inequality in Canada: An interprovincial perspective

This paper uses the Canadian Labour Force Survey to understand why the level and dispersion of wages have evolved differently across provinces from 1997 to 2013. The faster increase in the level of wages and the decline in wage dispersion in Newfoundland, Saskatchewan and Alberta are the starkest interprovincial differences. We find that they are accounted for by the growth in the extractive resources sectors, which benefited less‐educated and younger workers the most. Increases in minimum wages since 2005 are found to be the main reason why wages at the very bottom grew more than those in the middle of the distribution.     

Determinants of wage stickiness in a developing economy

We explore wage flexibility in a developing country and compare our results to what has been found in similar studies using European data. In particular, we conduct a survey of 1189 firms in Pakistan to analyze the determinants of wage rigidity. We find that the existence of competitive wages and an interaction with the informal economy are statistically significant determinants of wage stickiness. While the role of competitive wages is similar to what has been found in studies of European firms, the latter find a much larger role for turnover, collective bargaining and employment protection. In contrast, in Pakistan we find that firms hiring from the informal sector are significantly more flexible in changing their wages. This suggests that the informal sector adds to the wage flexibility of the formal sector.     

Spikes and spill-overs: The impact of the national minimum wage on the wage distribution in a low-wage sector

The UK National Minimum Wage (NMW) has had a minimal impact on UK wage inequality because it has been set at a modest level and because aggregate evidence suggests very small spill-over effects. But the small spill-over effects might be because of the small numbers of workers affected and widespread anticipation of the introduction of the NMW might make the impact effect appear very small. This paper investigates these issues using data collected from care homes where the NMW affected 40% of workers. But we still find no evidence of large spill-over effects and very small amounts of anticipation of the NMW.     

Wage inequality and overeducation in a model with efficiency wages

Abstract.  This paper shows that the existence and persistence of 'overeducation' can be explained by an extension of the efficiency wage model. When calibrated to fit the amounts of overeducation found in most empirical studies, the model implies that both the relative wage and the relative employment of high‐skill workers depend inversely on aggregate economic activity. Keeping aggregate employment constant, furthermore, low‐skill unemployment rises, following an increase in the relative supply of high‐skill labour, and relative wages may be insensitive to changes in relative labour supplies. The model may help to explain rising wage inequality in some countries since the early 1970s. JEL classification: J31     

Employment effects of introducing a minimum wage: The case of Germany

Income inequality has been a major concern of economic policy makers for several years. Can minimum wages help to mitigate inequality? In 2015, the German government introduced a nationwide statutory minimum wage to reduce income inequality by improving the labour income of low-wage employees. However, the employment effects of wage increases depend on time and region specific conditions and, hence, they cannot be known in advance. Because negative employment effects may offset the income gains for low-wage employees, it is important to evaluate minimum-wage policies empirically. We estimate the employment effects of the German minimum-wage introduction using panel regressions on the state-industry-level. We find a robust negative effect of the minimum wage on marginal and a robust positive effect on regular employment. In terms of the number of jobs, our results imply a negative overall effect. Hence, low-wage employees who are still employed are better off at the expense of those who have lost their jobs due to the minimum wage.     

The long-run consequences of minimum wage regulation in a monetary economy

This paper investigates the long-run implications of minimum wage regulation on the growth process with monetary repercussions. The paper shows, among other results, that if the minimum wage floor (MWF) is sufficiently low, then the qualitative behavior of the dynamic path is similar to the case of full employment in which the steady state is a saddle point, and that if the MWF is sufficiently high, the economy decays all the way toward the origin.     

Environmental control,wage inequality and national welfare in a tourism economy

This paper examines the effects of stricter environmental regulation on income distribution and welfare for an open economy with inbound tourism. The pollution input is considered as a mobile factor between sectors, and a decrease in it lowers wages of skilled labor in the traded sector but can increase the wages of unskilled labor in the non-traded sector. A stricter policy on environmental controls can narrow wage inequality and increase welfare if the tourism terms-of-trade effect dominates. These results are confirmed by simulations.
