Elasticity of substitution and productivity, capital and skill intensity differences across firms

This paper, instrumented with six theorems, shows that differences between firms in labor productivity, capital intensity and relative demand for skilled labor can be explained by differences in the substitution parameters between capital, skilled and unskilled labor in the presence of skill biased technical change.     

Unions and wage inequality: The roles of gender,skill and public sector employment

We examine the changing relationship between unionization and wage inequality in Canada and the United States. Our study is motivated by profound recent changes in the composition of the unionized workforce. Historically, union jobs were concentrated among low-skilled men in private sector industries. With the steady decline in private sector unionization and rising influence in the public sector, half of unionized workers are now in the public sector. Accompanying these changes was a remarkable rise in the share of women among unionized workers. Currently, approximately half of unionized employees in North America are women. While early studies of unions and inequality focused on males, recent studies find that unions reduce wage inequality among men but not among women. In both countries, we find striking differences between the private and public sectors in the effects of unionization on wage inequality. At present, unions reduce economy-wide wage inequality by less than 10%. However, union impacts on wage inequality are much larger in the public sector. Once we disaggregate by sector, the effects of unions on male and female wage inequality no longer differ. The key differences in union impacts are between the public and private sectors—not between males and females.     

Tobacco policy and tobacco use: differences across tobacco types,gender and age

Using state-level data for 1997, this paper studies the effectiveness of tobacco policies at reducing tobacco use across different population groups in the USA. The effectiveness of tax (price)-based and non-price tobacco policies are examined on tobacco prevalence (including cigarettes and smokeless tobacco) across gender and age. Besides shedding light on the efficacy of sub-national tobacco policies, the results also examine the extent of spillovers of policy actions across tobacco types. Significant differences in tobacco use are found across gender, age, policies, and between smoking and smokeless tobacco. Policy implications are discussed.     

New insights on earnings trends across skill groups and industries in West Germany

This paper provides an empirical analysis of the structure of earnings in West Germany across skill groups and industries. Our analysis is based on data from the German Socioeconomic Panel for the period 1984 to 1994. We estimate quantile regressions, both for the entire sample period and for each year separately, in order to obtain a finer picture of the earnings structure compared to conventional least squares methods. For robust standard error estimation, this study uses a block bootstrap procedure taking account of heteroskedasticity and autocorrelation in the error term. We also suggest a simple procedure to obtain a consistent estimate of inter-industry earnings variability. Our main findings are: first, pooled estimation comprising a uniform time trend is not rejected by the data, and second, the effects of human capital variables and industry dummies on earnings differ considerably across quantiles.

Factor market distortions across time,space and sectors in China

In this paper, we measure TFP losses in China?s non-agricultural economy associated with labour and capital misallocation across provinces and sectors between 1985 and 2007. We also decompose the overall loss into factor market distortions within provinces (between state and non-state sectors) and distortions between provinces (within sectors). Over the entire period, misallocation lowers aggregate non-agricultural TFP by an average of twenty percent. However, after initially declining, these losses increased appreciably beginning in the mid-1990s. This reversal can be attributed almost exclusively to increasing misallocation of capital between state and non-state sectors within provinces, while losses from between province misallocation remained fairly constant. We argue that the recent increase in capital market distortions is related to government policies that encourage investments in the state sector at the expense of investments in the more productive non-state sector.     

The wage effects of ethnicity in Estonia

Using the retrospective (1989-94) Estonian Labour Force Survey (ELFS), we attempt to examine potential wage discrimination based on ethnicity (Estonian and Russian). Using standard wage decomposition methodology, we look at male full-time workers in the years 1989 and 1994. There is no evidence of discrimination against either ethnic group in 1989. However, the available data provide substantial evidence of discrimination against ethnic Russians in 1994. The evidence also suggests that Estonian language ability does not significantly affect wages. Surprisingly, Estonian-born ethnic Russians appear to fare worse than immigrant ethnic Russians in terms of wages.

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

Trade,tasks and training: The effect of offshoring on individual skill upgrading

We offer a theoretical explanation and empirical evidence for a positive link between increased offshoring and individual skill upgrading. Skill upgrading takes the form of on‐the‐job training, complementing the existing literature, which mainly focuses on the retraining of displaced workers. To establish a link between offshoring and on‐the‐job training, we introduce an individual skill upgrading margin into the Grossman and Rossi‐Hansberg ( 2008 ) model of offshoring. By scaling up worker's wages, offshoring creates previously unexploited skill upgrading possibilities, which lead to more training. Using data from German manufacturing, we establish a causal link between industry‐level offshoring growth and increased individual skill upgrading.     

Financial deregulation,credit allocation across sectors,and economic growth: evidence from China

This paper investigates whether financial deregulation causes economic growth through financial development. Financial development is measured by two channels: (1) changes in the allocation of credit across sectors, and (2) changes in savings and investment rates. We measure financial deregulation in China at the provincial level from 1981 to 1998. Our results suggest that financial reform causes economic growth in China. Further, its effect largely comes through the reallocation of credit across sectors, rather than changes in savings and investment rates.     

Collective bargaining and regional wage differences in Spain: an empirical analysis

This article analyses the importance of labour market institutions and, in particular, collective wage bargaining in shaping regional wage differences in the Spanish labour market. Using microdata from the Spanish Structure of Earnings Survey, our results reveal that there are significant inter-regional wage differences for similarly skilled workers. These differences are present throughout the whole wage structure and can be explained by both competitive and non-competitive factors, such as insufficient competition in product markets. In this context, industry-level collective bargaining plays a major role in accounting for regional wage differences, a role that in the Spanish case is enhanced due to its unusual regional dimension.     

The effects of differences in year‐round,full‐time labor market experience on gender wage levels in the United States

This paper utilizes longitudinal information on annual hours worked to construct a more robust measure of labor market experience for young workers in the USA. This enhanced experience measure is then used to assess recent gender wage differentials. Our experience measure yields a dramatic improvement in the ability of standard earnings regressions to explain the variation in wages across individuals, especially for young women. In addition, our results indicate that approximately one‐fourth of the gender difference in average wages is attributable to the higher work experience levels of men.     

Investment in human capital and gender wage differences: evidence from the NLSY

This paper uses data from the National Longitudinal Survey of Youth (NLSY) to investigate gender differences in returns to various forms of human capital. Since the NLSY includes relatively detailed information regarding on- and off-the-job training, we place special emphasis on measuring gender differences in the incidence of and returns to formal post-school training. Also considered is the role of nonhuman capital factors such as industry and occupation in explaining the wage gap. It is found that about 60% of the gender wage gap in the sample is explained by mean differences in individual characteristics and market circumstances. This suggests a smaller role for discrimination in explaining the wage gap than previous research has found. The research indicates that training does not affect the gender wage gap. Also it is found that there is no statistically significant difference in the rate of return to other measures of human capital for women versus men. Our research suggests that the largest factors contributing to the wage gap are differences in the stocks of human capital for men and women, and differences in the distributions of men and women across industries and occupations.     

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.     

Analysis of wage differences between native and immigrant workers in Spain

This paper analyses the nature of wage differences between native and immigrant workers in Spain. By estimating separated wage equations for the sub samples of both native and non-native workers and applying the Oaxaca–Blinder method, we observe that the relative unexplained (or discriminatory) component of the wage difference has a decreasing behaviour along the most part of the wage distribution, even becoming negative at the end. So, in this paper we detect the existence of a remarkable wage difference against the group of immigrants with the lowest wages which is not explained by the differences in the productive features of both native and non-native workers. This paper has been funded by the project SEJ2004-04065/ECON. Previous versions of this article have greatly improved thanks to the comments of two anonymous referees and the Managing Editor.     

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.     

Incidence theory and the shifting of protection across sectors: the South Asian experience

Using the theoretical framework of a simple general equilibrium model, this paper examines whether strategies aimed at protecting or promoting manufacturing industries indirectly taxed the agricultural and service sectors. A panel data set consisting of five South Asian countries over a 26 year time period is employed in the analysis. Three different estimation procedures are used to account for factors that are country specific and those that are common to all countries. The results indicate that the agricultural sector indirectly felt the brunt of the net protection provided to manufactures due to the ‘shifting of protection’ across sectors. The service sector, on the other hand, indirectly benefited from the general equilibrium spillover effects.     

The economic effects of improving investor rights in Portugal

The Portuguese economy has performed remarkably well since joining the EU in 1986. Output per worker grew at an annual rate of 2.25%. The relative price of investment has declined. Real investment has increased compared to output, in part fuelled by an increase in capital inflows. At the same time, resource allocation seems to have improved as well: firm-level data shows a significant decline in the dispersion of labor productivity and size across firms. This paper argues that improvements in outside investor rights that have taken place since Portugal joined the EU is a prime candidate to explain this set of facts.

The minimum wage, employment, and the AS-IF methodology: A forecasting approach to evaluating the minimum wage

Out-of-sample employment forecasts for 33 U.S. industries which are likely to be sensitive to the federal minimum wage are, more often than not, more accurate when information about the minimum wage is not taken into account. This is true even in instances where this information improves wage forecasts. When employment forecasts conditional on the minimum wage are better, the improvement is typically small. These results are invariant to the number of workers previously making less than the new minimum wage, and to the value of the minimum wage relative to industry average wages.

Closing the gap: The employment and unemployment effects of minimum wage policy in Puerto Rico

This paper examines the dynamic effect of minimum wage policy on employment and unemployment using multivariate time series techniques. The particular minimum wage policy being considered occurred in Puerto Rico in 1974 when it was decided to close the minimum wage gap between the island and the United States incrementally by 1980. Multivariate transfer functions are specified with the intent of distinguishing between minimum wage policy effects and structural changes brought about by the post-1974 recessions. The results suggest that minimum wage policy gave rise to more significant unemployment than disemployment effects. The pattern of labor mobility supports that suggested by the development literature in which labor flows from uncovered to covered sectors. However, given the structure of welfare programs on the island, it is likely that flows from the covered to the non-market sector also took place.
