TRADE,GEOGRAPHY AND THE SKILL PREMIUM IN U.S. MANUFACTURING

A number of studies have suggested that countries (or regions) with access to larger markets have higher wages. In this paper, we examine whether access to larger markets affects skilled and unskilled workers differently. We develop a model relating two key measures of market size, market and supplier access, to industry value added prices. We then estimate the effects of growth in these measures on factor returns in U.S. manufacturing industries between 1984 and 1996. We find that growth in these measures can explain around 5% of the rise in the skill premium over the sample period. (JEL F12, F16, L60)     

Firm-Level Hiring Difficulties: Persistence,Business Cycle And Local Labour Market Influences

We examine the correlates of reported hiring difficulties at the firm level using linked employer-employee and panel survey data over 2005-2011, focussing on the relative influence of firm-level characteristics, persistence, the business cycle and local labour market liquidity. At both the aggregate and the firm level, hiring difficulties eased after the onset of the Global Financial Crisis. Even in the presence of large cyclical changes in demand and labour market conditions, firm-level persistence is a dominant feature of the data, with one- and two-year lags of reported hiring difficulties both positively related to current difficulties. Firms paying higher wages are more likely to report difficulties when trying to hire skilled workers, while firms with more long tenure workers are less likely to report any difficulty hiring. Local labour market conditions appear unrelated to reported hiring difficulties.     

Of Skilled Migration,Brain Drains and Policy Responses*

Developed countries are increasingly trying to attract skilled migrants, rarely giving any consideration to the impact that this migration might have on countries of origin. The debate on the “brain drain” is not new but it has taken on greater urgency in the context of a globalizing economy and ageing societies and this article reviews the evidence over time and space. It examines opposing interpretations of the impact of the skilled from countries of origin and goes on to examine the particular case of the migration of health professionals. Health workers are seen to be key to achieving basic welfare objectives in any country and their loss may be critical to countries of origin. Hence, the movement of health professionals may be central to any understanding of a brain drain. However, the case for a brain drain, even in this sector, is not straightforward. Specific country and place of origin of the skilled, place of training, appropriateness of training, fit of skills to needs, and the role of return and inmigration of health professionals all need to be taken into consideration. The article examines the case for a two‐tiered health training system, one for global markets and the other for local markets. Retention and return of the skilled are examined through the potential for outsourcing in both education and health care. The article concludes with an examination of policy approaches towards skilled migration and offers pointers towards a more balanced and integrated approach by placing the emphasis on development rather than control of migrants.     

OFFSHORING PRODUCTION: A SIMPLE MODEL OF WAGES,PRODUCTIVITY, AND GROWTH

We examine the relationship between offshoring and the labor market in an occupational choice model of trade and endogenous growth where workers are employed on the basis of their individual skill levels. Trade liberalization leads to offshoring and reduces employment in the manufacturing sector. Displaced workers move into traditional and innovation sectors according to their skill levels, shaping real wages and aggregate productivity in the manufacturing sector. The paper aims to show how inter‐sectoral labor market adjustments, highlighted by skill heterogeneity, could be a possible explanation for the simultaneous rise in productivity and reduction in real wages that have coincided with the sharp escalation of offshoring activities in the U.S. manufacturing sector since 2004.

INTERNATIONAL OUTSOURCING AND THE PRODUCTIVITY OF LOW-SKILLED LABOR IN THE EU

This article presents first insights into the role of international outsourcing on the productivity of low-skilled workers in EU manufacturing. Whereas in the short run international outsourcing exhibits a negative marginal effect on real value added per low-skilled worker, the long-run parameter estimates reveal a positive impact. This may be explained by imperfections in European labor and goods markets, which prohibit an immediate adjustment in the factor employment and the output structure. The change in the outsourcing intensity since 1993 alone acounts for a long-run increase of about 6.0% in the real value added per low-skilled worker. (JEL C33 , F14 , F15 )     

Immigration and the Wages of Native Workers: Spatial versus Occupational Approaches

Using data from the Current Population Survey, we study the impact of the increasing proportion of immigrants on the wages of native workers. Two different approaches are contrasted. The most common method has been the spatial approach that uses some geographic unit of analysis to investigate the multivariate association between the proportion of immigrants and the wages of native workers. Previous studies using the spatial approach have generally found little evidence of a significant negative effect. We propose, however, a contrasting method that represents an occupational approach in which occupations are the unit of analysis to investigate the impact of the proportion immigrant. This occupational approach avoids the bias that is inherent in the spatial approach due to the endogenous nature of immigrants' decisions about where to reside and the economic opportunities of local areas. In contrast to the spatial approach, our results using the same data but employing the occupational approach yield consistently negative net effects of the proportion immigrant on the wages of native workers during the period from 1994 to 2006.     

How information technology affects wages: Evidence using internet usage as a proxy for IT skills

Many research studies have found a positive link between information technology (IT) in the work place and wages. Using data from the December, 1998 Current Population Survey, we examine the impact of IT, as proxied by on-the-job Internet usage, on wages. After controlling for selectivity bias, we estimate an average wage gain of 13.5 percent for on-the- job Internet usage. This wage advantage is consistent with estimates from studies based on data collected earlier in the 1990s examining the impact of computers in the workplace. We also tested for differences across industries in the manufacturing sector. We conclude that industries marked by less intensive use of technology offered significantly higher wage premiums than industries characterized by more intensive use of technology. This finding undermines the argument that higher wages go to those working in high-tech firms, not to those with high IT skills. We also find evidence that high-tech firms sort workers by skill level, which is also consistent with earlier studies.     

The level and growth of union/nonunion relative wage effects, 1967–1977

This paper pools cross-section data to obtain an estimate of the overall effects of unions on relative wages for the period 1967 through 1977. We found the average union wage premium for all workers to be roughly 24 percent, but that this premium varies substantially between subgroups of workers. Our analysis showed that real wage rates increased faster in the union sector than in the nonunion sector between 1967 through 1977. However, we found that this relative growth pattern in wages was caused by economic conditions rather than in any fundamental shift in the power of unions. We wish to thank James S. Cunningham, H. Gregg Lewis, and John Pencavel for helpful comments.     

Temporary Skilled Migration to Australia: Employers' Perspectives1

With the 1996 introduction of a new visa making it easier for employers to sponsor skilled foreign workers, temporary skilled migration has become a significant component of international migration flows to Australia. This paper examines employers' reasons for sponsoring skilled workers from abroad, their modes of recruitment, the occupational skills they require, and their industry profile. We also discuss issues relating to the perception of a shortage of skilled workers, the extent that sponsoring foreign workers substitutes for investing in local training, and the role of networks in recruiting overseas workers. Many employers' now have a global view of labour recruitment. While this is understandable for multinational companies with global operations, many small businesses and public sector institutions are adopting the same strategy to obtain skilled labour which they say is in short supply in Australia. With the internationalization of the Australian economy, there is also an increasing demand for people with specialized skills and knowledge that is not available in Australia's relatively small labour market. An understanding of the demand factors motivating temporary skilled migration is crucial to effectively managing Australia's migration and labour trends.     

Noncitizen Employment and the Wages of Healthcare Support Workers in the US

This study examines the relative wages of citizens and noncitizens employed as healthcare support workers as well as examines the effect of noncitizen support worker employment on the wages of citizen support workers. Relative wage findings reveal noncitizen support workers with less than eight years of US residency receive a noncitizen-citizen wage discount statistically significantly greater than the legal maximum of 5% below the local prevailing wage. These low relative wage levels could contribute to lower wages for citizen support workers, however elasticity of substitution findings suggest noncitizen support workers are not close substitutes for healthcare support workers who are US citizens. In addition, wage effect findings do not reveal a negative influence of noncitizen employment on the wages of native born US citizen support workers, while these findings reveal a relatively small wage decline for naturalized support workers. These findings are consistent with the citizen status job heterogeneity hypothesis. Nonetheless, finding noncitizen-citizen wage differences does not allow for ruling out the possibility of weak enforcement of prevailing wage legislation and possible employment of undocumented workers.     

ANTI‐POACHING AGREEMENTS IN LABOR MARKETS

We analyze competition for experienced workers among wage‐setting firms. The firms can design poaching offers with higher wages to workers who switch from rivals relative to wages paid to their own existing employees. We evaluate the profit and welfare effects of anti‐poaching agreements that eliminate poaching offers as a recruiting method. Anti‐poaching agreements increase industry profits, whereas workers are made worse off. We show that the effects of anti‐poaching agreements on total welfare are determined by the magnitude of workers' switching costs and the productivity change associated with switching employers.

BRAIN DRAIN IN GLOBALIZATION: A GENERAL EQUILIBRIUM ANALYSIS FROM THE SENDING COUNTRIES' PERSPECTIVE

According to the economic literature, high‐skilled emigration may either harm or benefit developing economies. Recent research highlighted several positive and negative channels through which the brain drain operates. This paper aims at evaluating the relative magnitudes of various brain drain channels and quantifying their global impact on migrants' sending countries. For this purpose, we develop a 10‐region general equilibrium model of the world economy characterized by overlapping‐generations dynamics. Our findings suggest that the short‐run impact of brain drain on resident human capital is extremely crucial, as it affects not only the number of high‐skilled workers available to domestic production, but also the sending economy's capacity to innovate/adopt modern technologies. This latter effect is particularly important in globalization, where capital investments are made in places with high production efficiencies. Hence, despite positive feedback effects, those countries facing prevalent high‐skilled emigration are the most candid victims to brain drain. (JEL F22, J24, O57)     

Gender segregation and the wage gap in Portugal: an analysis at the establishment level

Using a large linked employer-employee data set, this paper aims at quantifying the trend in worker segregation at the establishment level and its impact on wages in Portugal over a fifteen year period. We concentrate on the gender dimension, to answer the questions: What is the level of gender segregation across establishments in the Portuguese labor market and how has it evolved over time? What is the impact of segregation on wages? Is that impact different for men and women? Systematic and random components of segregation are computed. We use standard wage decomposition techniques to evaluate the impact of the composition of the labor force at the establishment level on wages. The results reveal a high degree of systematic gender segregation. A higher proportion of females in the establishment lowers females’ wages while, on the contrary, it raises males’ wages. The evidence gathered is consistent with the taste-based model of employer behavior and with the theory of sorting of workers across establishments based on their productivity.     

On the integration of labor markets: A definition and test of the radical — Segmentation hypothesis

The empirical results of this paper are indicative of overall labor market integration. Segmentation theories are not supported by the high covariability of wage rates supported by this test. If segmentation theories are to mean more than that relative wages differ among industries, proponents of such theories must argue that segmented markets are cut off from other markets and able to resist the forces of supply and demand. Indeed if labor unions are to be able to insulate workers from market forces they must also segment their markets. The results of this paper indicate that unions are not able to insulate their workers from market forces. We are grateful to William Boyes, Dennis Logue, John Bishop, Stephen E. Baldwin, William McEachern, Roger Sherman, and Robert Tollison for comments on earlier versions and to James Bennett and an unidentified referee for comments on this final version.     

FINANCIAL DEVELOPMENT AND WAGE INEQUALITY: THEORY AND EVIDENCE

We argue that financial market development contributed to the rise in the skill premium and residual wage inequality in the United States since the 1980s. We present an endogenous growth model with imperfect credit markets and establish how improving the efficiency of these markets affects modes of production, innovation, and wage dispersion between skilled and unskilled workers. The experience of U.S. states following banking deregulation provides empirical support for our hypothesis. We find that wages of skilled workers increased by between 0.5% and 6.3% following deregulation while those of unskilled workers fell by between 3.5% and 8.7%. Similarly, residual (or within‐group) inequality increased; the 90–50 percentile ratio of residuals from a Mincerian wage regression and their standard deviation increased by 4.2% and 1.7%, respectively.

Minimum Wages in a Segmented Labor Market: Evidence from South Africa

The segmented labor market model describes the impacts of minimum wages on covered and uncovered sectors. This paper examines the impacts of an industry-specific minimum wage in South Africa, a state characterized by high unemployment, a robust union movement, and the presence of a large informal sector. Under the industry-specific wage law, formal agricultural and household workers are covered, while workers in other sectors are not. The unique aspect of this paper lies in the ability to compare the impacts of minimum wage legislation on formal covered, informal covered, formal uncovered, and informal uncovered workers. This natural experiment allows us to test whether industry-specific minimum wage legislation leads to higher wages, whether wage increases are restricted solely to covered formal sectors or if there are spillover effects, and whether such legislation manifests in disemployment effects. We find evidence of higher wages yet disemployment among black workers in formal markets. In informal markets we find no employment effects, but higher wages in formal markets appear to have spilled over into informal markets in covered sectors.     

Unemployment,union density,and wages

We investigate, both theoretically and empirically, whether long-run industry unemployment rates modify the wage impact of union density on the earnings of members. Our theory suggests that the density effect increases as unemployment increases. Our empirical estimates use wage equations exclusive and inclusive of unemployment and of the interactive effect of unemployment and density in influencing wages. Based on a 1985 sample of manufacturing production workers, our findings indicate that the wage effect of union density for union workers as usually measured is only 41 percent as large as the effect when unemployment is in the model.     

"BUMPING", LAYOFFS, AND WORKSHARING

This paper deals with an interesting but often-neglected labor practice prevalent in large North American firms with well-developed internal labor markets. Large North American firms typically respond to a decline in demand for their products by first reducing the number of hours worked (or worksharing). As the demand continues to fall, however, they begin to make skilled workers "bump onto" unskilled jobs, displacing unskilled workers. Skilled workers are laid off only after a considerable number have bumped. I develop an implicit contract model and explain the practice.     

Regionalization,economic restructuring and labour migration in Singapore

This paper documents the impact of economic development on changes in employment and labour migration in Singapore.
High export-led growth and the relaxation of immigration policies in the late 1960s enabled employment of substantial numbers of unskilled foreign labour in manufacturing, construction and domestic service sectors. Unskilled foreign labour in Singapore now totals about 350,000 or 20 per cent of the labour force. It has made possible an augmentation of domestic labour supply and skills which helped Singapore to achieve higher rates of economic growth. On the negative side, the influx of foreigners has been cited as one possible cause of low productivity growth in the 1970s. In addition to the increased demand on housing, the social costs of crime and the potential economic consequence arising from strained diplomatic ties with the source countries are also areas of concern.
Economic development in the 1990s, characterized by the regionalization drive which relocates relatively resource-intensive operations of Singapore-based companies overseas, has led to increased retrenchments and a moderation of demand for foreign workers. The upgrading of remaining production operations in Singapore is expected to increase demand for workers with higher skill levels. Emigration of highly educated and skilled professionals from Singapore became a national concern in the late 1980s. However, with regionalization, the new challenge in the 1990s has become one of encouraging Singaporeans to temporarily take up overseas positions.
The future foreign labour pool in Singapore is expected to comprise a growing proportion of skilled workers to sustain the 7–8 per cent economic growth rate in the medium term. Slower economic growth in the developed economies and the internationally competitive salaries paid to professionals in Singapore are expected to continue to reduce the outflow of permanent emigrants from Singapore.     

IMMIGRATION,SKILL HETEROGENEITY,AND QUALIFICATION MISMATCH

We investigate the effects of U.S. immigration in a comprehensive search and matching framework that allows for skill heterogeneity, imperfect substitutability between skilled and unskilled inputs, different search cost between natives and immigrants, cross‐skill matching, and imperfect transferability of foreign human capital. When we simulate the effects of the U.S. immigration that took place between the years 2000 and 2009, we find that both skilled and unskilled natives, as well as skilled and unskilled immigrants, gain in terms of income and employment. We also investigate the effects of an improvement in the transferability of human capital across borders and find that, although it has some redistributive effects, overall it benefits both immigrants and natives.
