A Welfare Analysis of Policy Responses to the Skilled Wage Premium

I build a model with heterogeneous agents which is consistent both with rising wage inequality across education levels and with an increasing relative number of college graduates. I use the model to investigate the welfare implications of policies which influence the structure of net wages. Each policy affects agents directly through taxes and subsides and indirectly as wages respond to changes in the relative supply of skilled and unskilled workers. I find that as wage inequality grows due to skill-biased technological change, policies which promote a more egalitarian wage structure can become increasingly acceptable to all agents and that for nearly all agents, education subsidies may be preferred to direct transfers as a means of decreasing wage inequality.

Spatial price dynamics and integration in russian food markets

In general, vocational education does not lead to higher wages. However, in some countries, labor markets are characterized by employment growth and skill shortages. In these, vocational schooling has produced higher wages and returns on investment than general education. Using 1998 Egyptian household survey, the study adds evidence to the debate on relative benefits of vocational education and of general education at the secondary level. The findings suggest that providing general education to the workforce followed by on-the-job training would provide the most benefit.     

Testing for uniform wage trends in West-Germany: A cohort analysis using quantile regressions for censored data

The rise of unemployment in West Germany is often attributed to an inflexibility of the wage structure in the face of a skill bias in labor demand trends. In addition, there is concern in Germany that during the 70s and 80s unions were pursuing a too egalitarian wage policy. In a cohort analysis, we estimate quantile regressions of wages taking account of the censoring in the data. We present a new framework to describe trends in the entire wage distribution across education and age groups in a parsimonious way. We explore whether wage trends are uniform across cohorts, thus defining a macroeconomic wage trend. Our findings are that wages of workers with intermediate education levels, among them especially those of young workers, deteriorated slightly relative to both high and low education levels. Wage inequality within age-education groups stayed fairly constant. Nevertheless, the German wage structure was fairly stable, especially in international comparison. The results appear consistent with a skill bias in labor demand trends, recognizing that union wages are only likely to be binding floors for low-wage earners.     

The wage gap between Francophones and Anglophones: a Canadian perspective, 1970–2000

Abstract. The wage gap between Francophone and Anglophone men from 1970 and 2000 fell by 25 percentage points within Quebec, but only by 10 points Canada‐wide, largely because the wages of Quebec Anglophones fell by 15 points relative to other Canadian Anglophones. Accordingly, the Canadian measure of the Francophone gap better reflects the changing welfare of Francophones than the Quebec measure. Over half of the reduction in the Canadian Francophone wage gap is explained by rising Francophone education levels. In Quebec, the declining number and relative wages of Anglophone workers is best explained by a falling demand for English‐speaking labour.     

Long-run relations between private and public sector wages in Sweden

Using a maximum likelihood cointegration approach we find two long-run relationships between central government, local government, and private sector wages in Sweden. This means that there is one common trend for the three sectoral wages. Private sector wages are weakly exogenous for the estimation of the long-run relationships. This suggests that the private sector is the wage leader. Testing linear restrictions on the estimated cointegrating space, we reject stationarity for the three relative wages using likelihood ratio-tests. The hypotheses of homogeneity for the two cointegrating vectors, i.e., that wages do not diverge in the long run, is also rejected.     

Changes in Wages,Wage Inequality and the Return to Human Capital Skills in Kenya: 1977–2005

The conventional literature on wage inequality in Kenya has two drawbacks: first, by focusing on manufacturing sector wages, overlooking wages in other sectors, the results may be biased. Second, previous studies emphasize wage determination solely at the conditional mean rather than resort to wage determination across the entire earnings distribution. We remedy these weaknesses and add a new layer of research previously unexamined. Particularly, we consider wage changes during periods of wide GDP fluctuations from 1977 to 1986, 1986 to 1999, and 1999 to 2005 and explore if prices of measured human capital skills moved in tandem with changes in the dispersion of unmeasured human capital skills as is postulated by human capital theory. Our results support human capital theory: we find higher wages and higher residual wage dispersion during periods of rising GDP (1999–2005) but find lower wages and lower residual wage dispersion during periods of falling GDP (1977–86 and 1986–99).     

Like father like son? Revisiting the role of parental education in estimating returns to education in China

Parental education has been used as an instrument in the earnings equation to deal with the endogeneity problem of education. Recently, however, many have found that parental education can be a proxy for unobservable networking, which directly affects wages. This article revisits the role of parental education in estimating returns to education by introducing the “geographical isolation” theory. For migrant workers who receive an education and move around to work, parental education affects their education but otherwise is unrelated to their wages, which makes parental education a good instrument in the instrumental variable approach. For local residents who stay in the same place during childhood and adulthood, parental education can directly affect their wages, and is better introduced as a proxy variable using the control variable method. This article identifies the heterogeneous effect of parental education on wages for different Chinese cohorts and contributes to the debate between the control variable and instrumental variable methods in returns to education studies. Moreover, the idea of geographic isolation can help in the search for good instrumental variables for migrant workers, which is valuable when studying the large migrant population in developing countries such as Mexico, China, India, Vietnam, and many African countries.     

Canadian wage inequality over the last two decades

We study the dispersion of wages of full-time full-year workers over two decades controlling for both education and experience. Applying non-parametric statistical methods we find statistically significant and large increases in inequality for males with low levels of education and experience coexist with more modest changes in inequality for those with average education and experience, and with actual declines in inequality for older, more experienced workers with a university degree. These relative patterns tend to be similar for females though with a stronger tendency towards inequality in each education-experience category. Given the recent focus in this debate on the issue of polarization, we also show graphs of the actual distributions of wages and analyze these to conclude that the groups experiencing increased dispersion do display what is commonly known as polarization though it would be an exaggeration to claim that the jobs in the middle of the distribution have vanished.

The Increase in College Premium and the Decline in Low‐Skill Wages: A Signaling Story

The increase in the college premium over the last 30 years in the United States is to a large extent driven by a reduction in noncollege wages. We show that the signaling effects triggered by an improvement in the incentives to attend higher education can explain this fact, as well as the increase in the number of college graduates. Under imperfect credit markets and wealth heterogeneity, higher education is not only a signal of ability but also of individuals' (parents') wealth. General conditions on the distribution of wealth guarantee that after an increase in incentives to attend higher education, the absence of a college degree becomes a more evident signal of low ability. This results in a reduction in low‐skill wages but not necessarily in increased high skill wages. The increased incentives to enroll in college can either arise from a skill‐biased technology change or an improvement in access to higher education. An important difference is that while skill‐biased technology change always results in an increase in the college premium, that is not necessarily the case when the increased incentives to enroll arise from improved access to higher education.     

Increasing wage dispersion and the changes in relative employment and wages in Mexico's urban informal sector: 1987-1993

This study analyses the role of changes in informal/formal relative employment, wage levels and wage inequality in explaining increasing wage dispersion in Mexico during the 1987–1993 period. From 1987 to 1993, the variance of the log of hourly wages for Mexican workers increased by more than 50 per cent. Using data from the Encuesta nacional de empleo urbano we find that this increase in the overall wage dispersion was mainly driven by increasing wage dispersion in the formal sector coupled with a faster growth in formal sector employment as a percentage of total employment. However, compression in the distribution of wages within the informal sector contributed to substantially slowdown the increasing overall wage inequality. About 60 per cent of the 1987–1993 4.65 percentage point reduction in the informal sector share of total employment is explained by changes in the structure that determines sectoral employment; the rest is explained by changes in the composition of the labour force, particularly increases in the sectoral education gap and a change in the regional relative share of sectoral employment. Also, from 1987 to 1993 the sectoral wage ratio increased from 0.59 to 0.63. It seems that a relative improvement in unobserved skills in the informal sector helped to close the wage differential but this effect was partially offset by an increase in the relative prices of both observed and unobserved skills, as well as increases in relative observed skills in the formal sector, particularly education.     

The Spatial Determinants Of Wage Inequality: Evidence From Recent Latina Immigrants In Southern California

Abstract

Recent Latina immigrants to the United States earn lower hourly wages than any other broad demographic group. This paper investigates the role space and scale play in shaping the employment opportunities and wages this group receives in Southern California relative to others there. Results suggest that, although individual factors such as education, experience, and ability to speak English are important, spatial forces also influence wages. Access to jobs, particularly low-skilled jobs and those held by Latinos, as well as ethnic neighborhood networks, explain a large share of the variation in hourly wages. The paper provides evidence that labor-market scales differ across groups within US metropolitan areas, with recent Latina immigrants being more geographically constrained and hence more dependent on local opportunities and resources than other workers, with the exception of black women.     

How Does Imperfect Competition in the Labor Market Affect Unemployment Policies?

We consider a continuum of workers ranked according to their abilities to acquire education and two firms with different technologies that imperfectly compete in wages to attract these workers. The education cost to be borne by workers is higher in the high-technology firm. In equilibrium, we show that the unemployed workers are those with the lowest initial abilities. We then study different policies that subsidize either education cost or wages. We found that the first-best allocation can only be implemented by selective policies. We analyze second-best nonselective policies and show that, in terms of welfare, subsidizing education costs or wages is strictly equivalent.     

Evaluating the Impact of Educational Expansion on the Occupational Status of Youth

This paper exploits the remarkable increase in the average educational attainment of Australian youth during the 1980's to evaluate the role of education in labour market performance. Rather than focus on the impact of schooling on wages, however, we examine changes in the occupational distribution of recent labour market entrants. The evidence indicates that the educational expansion appears to move all individuals up the educational ladder without altering their relative position. The results indicate that while the second cohort obtained substantially more education than the first cohort the occupational distribution of the two cohorts were almost identical. Furthermore, there was no evidence that the increased education counterbalanced changes in the structure of labour demand or manifested itself in higher wages.     

Education, Work and Wages in the UK

Abstract. This paper is concerned with the relationship between education, wages and working behaviour. The work is partly motivated by the sharp distinction in the literature between the returns to education and the effect of wages on labour supply. Education is the investment that cumulates in the form of human capital while labour supply is the utilization rate of that stock. Yet, variation in education is usually the basis for identifying labour supply models – education is assumed to determine wages but not affect labour supply. Moreover, it is commonly assumed that the private rate of return to education can be found from the schooling coefficient in a log-wage equation. Yet, the costs of education are largely independent of its subsequent utilization but the benefits will be higher the greater the utilization rate. Thus the returns will depend on how intensively that capital is utilized and we would expect that those who intend to work least to also invest least in human capital. Indeed, the net (of tax liabilities and welfare entitlements) return to education will be a complex function of labour supply and budget constraint considerations.
Here we attempt to model the relationship between wages, work, education and the tax/welfare system allowing for the endogeneity of education as well for the correlations between the unobservable components of wages and working behaviour. We use the estimates to simulate the effect of a new UK policy designed to increase education for children from low-income households.     

Why has wage inequality increased more in the USA than in Europe? An empirical investigation of the demand and supply of skill

During the past two decades the wage gap between high and low skill labour has increased more in the USA than in many European countries. In this paper, the correspondence between occupation and education is used to construct aggregates of skill supply, skill demand and unemployment by skill group that are comparable across countries. Using individual data for years 1983–1994, it is found that the relative demand for skilled labour has increased to a similar extent in the USA and in Europe and that wage inequality remained low in Europe partly because the European relative supply of skill increased much faster than in the USA, and partly because European relative wages were rigid, which caused an increase in unemployment among the low-skilled.     

THE IMPORTANCE OF SKILL MEASUREMENT FOR GROWTH ACCOUNTING

In a growth accounting context one usually constructs a quality adjusted index of labor services by aggregating over predefined groups of workers, using the groups' relative wage bills as weights. In this article we suggest a method based on decomposing individual predicted wages into a skill‐related part and a part unrelated to skill, where the former consists of both observed and unobserved components. The predicted wages, associated with individual skill attributes, are sorted and classified into deciles. The median predicted skill‐related wage in each decile is used to construct an alternative skill‐adjusted index of labor services. We find that total factor productivity (TFP) growth decreases significantly when using the latter method. This means that when using the alternative method one explains more of the growth in labor productivity than what a more traditional labor quality adjustment procedure does.     

中国高等教育投资风险和收益的实证研究

With the expanding of higher education in China from 1999, more and more youngsters are able to invest in higher education, resulting a high unemployment rate for higher education graduates and more and more graduates employed in non-graduate position, while the analysis upon risk and return to each level of high education is absent due to the limitation of dataset. The paper employs college students sample survey to research the determinants of all levels of higher education beginning wages, the probability to find an appropriate job in order to conclude the risks and returns to each level of higher education based on the wages growth rate and economic development. The research finds the return to master degree is the highest, but the risk is the lowest in China.      

Measuring heterogeneity in the returns to education using an education reform

In this paper, we explore the impact of a mandatory education reform as well as pre-reform availability of schools above the mandatory level, on educational attainment and returns to education in Norway. We contribute to the existing literature by focusing on the heterogeneity of the impact of reforms. Our results indicate that increased compulsory education from seven to nine years increased the general level of education beyond the compulsory education. We also find that the effect of family background on educational attainment was weaker after the reform. The average treatment effect on returns to education is surprisingly high for education of intermediate duration. This means that increasing the general level of education potentially generates high returns in the form of wages. We also find that the effect of treatment on the treated on the returns to education is 1-4 percentage points higher than the average treatment effect.     

WAGES AND EMPLOYMENT IN THE U.S. APPAREL INDUSTRY

This article uses individual-level data from the U.S. Census, Public Use Microdata Sample (PUMS), to examine wages and employment in the U.S. apparel industry. Total employment in this sector has been falling since 1970, and its overall average wage is the lowest of 25 industry aggregates. But disaggregation by gender, education, and nativity reveals that groups of highly educated male native workers earn higher average wages in apparel than in other industries. Moreover, after adjusting for observed individual differences in human capital (in addition to the three characteristics used to form worker subsets), highly educated male natives earn positive wage premiums in this sector. In contrast, most categories of immigrants and female natives earn relatively low average wages and experience negative wage premiums in apparel. This variation in the adjusted industry wage premiums across worker groups may be related to apparel's relative exposure to imports and immigrant workers.
