Educational Attainment and the Lesbian Wage Premium

This paper provides insight into the wage gap between lesbians and heterosexual women. Using data from the 2000 Decennial Census, we find a lesbian premium that equals approximately 10% for women without a bachelor’s degree, and is nearly non-existent for women with higher levels of education. These findings are consistent with proposition that the gap between lesbians’ and heterosexual women’s commitment to the labor market narrows at higher levels of education. We also find that controls for industry and occupation exert only a small effect on the gap between lesbian and heterosexual women’s wages.

Immigrant Wage Disadvantage in Sweden and the United Kingdom: Wage Structure and Barriers to Opportunity1

This article examines immigrant/native-born wage inequalities among workers in two Western European countries: Sweden, social democratic and with comparatively low wage dispersion, and the United Kingdom, economically liberal and with comparatively high wage dispersion. The analysis includes immigrants from 26 countries of origin. Findings demonstrate that inequalities in terms of real wages are smaller in more egalitarian Sweden. However, in terms of relative positions within the labor market, inequalities are if anything smaller in the UK. These findings highlight the role of wage dispersion in magnifying immigrant disadvantage, but also the limits of wage compression for ameliorating barriers to immigrant opportunity.     

Wage Decompositions with Selectivity-Corrected Wage Equations: A Methodological Note

This paper examines the implications of the standard Heckman (Heckit) correction for selectivity bias in wage and earnings functions that are subsequently used in wage decompositions. Even when justified, Heckit selectivity correction introduces some fundamental ambiguities in the context of wage decompositions. The ambiguities arise from group differences in the selection term which consists of a parameter multiplied by the Inverse Mills Ratio (IMR). The parameter is identified as the product of the standard deviation of the errors in the wage equation and the correlation between the wage equation error and the selection equation error. How should group differences in these parameters be interpreted in terms of structural differences and endowment effects? The same issue arises with respect to group differences in the IMR which reflect nonlinear group differences in the determinants of selection and in the probit coefficients.     

Intangibles and the Gender Wage Gap: An Analysis of Gender Wage Gaps Across Occupations in the Finnish Private Sector

The paper compares the gender wage differentials of two occupation groups—innovation and non-innovation workers—separately for manufacturing and services using Finnish private-sector data. We apply a decomposition method based on unconditional quantile regression techniques to identify key factors underlying the gender wage gaps observed along the whole wage distribution, as well as changes in these wage gaps between 2002 and 2009. This more nuanced approach provides important new insights. We find conspicuous differences in average gender wage gaps, in gender wage-gap profiles across the wage distribution and also in the evolution of gender wage differentials over time between sectors and occupation groups. Our results imply that sector-specific factors are a more important driving force behind these differences in patterns and trends of gender wage gaps, although occupation-specific factors cannot be totally dismissed. Hence, comparisons of gender wage gaps, including their underlying sources, of innovation and non-innovation workers for too broadly defined segments of the labour market may result in misleading conclusions concerning the factual role of intangible capital.     

Gender,Productivity, and the Marital Wage Premium

Explanations for married men’s wage premium often emphasize greater market productivity due to a gendered division of household labor, though this “specialization thesis” has been insufficiently interrogated. Using data from Wave 2 of the National Survey of Families and Households (N = 972), this paper examines the relationship between wages and time spent in paid labor and housework for married women and men with high levels of labor force attachment and their spouses. Scrutiny of couples’ time use finds strong evidence for the gendered division of labor, but little support for the anticipated wage effects of the specialization thesis itself. Less strict sample restrictions point to the need for continued research directed at couples’ joint employment and household labor decisions.     

Testing Fair Wage Theory

Fairness considerations often are invoked to explain wage differences that appear unrelated to worker characteristics or job conditions, but non-experimental tests of fair wage models are rare because market data rarely permit researchers to measure individual workers’ productivity and its value. We use data from the baseball labor market to address this problem, and find no support for fair wage theory. We do find, however, that fairness premia can be illusory: Wages appear to incorporate fairness premia in regressions that control for variation in individuals’ physical output, but such premia evaporate when the value of that output is held constant.

Trade and Wage Inequality in Developing Countries

In this article we provide a theoretical analysis of the possible impact of trade and fragmentation on the skilled–unskilled wage gap in a small developing economy. In particular, we illustrate the possibility of a decline in the relative wage of the unskilled labor following an improvement in the terms of trade. (JEL F1 , F11 , F12 )     

Union Worker Wage Effect in the Public Sector

This study examines union wage premiums in the public sector for the 1998–2004 period. Unlike previous studies, our approach estimates union wage premiums considering differences in the rewards to education, experience, and other personal characteristics for union and non-union workers. The approach provides a larger estimated wage gap than the traditional approach, and allows for simulations of union–nonunion wage gaps for different types of workers. Moreover, we use an Oaxaca decomposition to explain the larger union–nonunion wage gap in the private sector in comparison to that in the public sector. We find that between 50% and 60% of the difference in union wage premiums between the private and public sectors is due to differences in the way unionized workers are rewarded in the private and public sectors, while the remaining portion is due to differences in personal characteristics of private and public sector workers.

Visualising Gender Wage Differences in the European Union

The purpose of this article is to illustrate differences in the gender wage gap in 13 EU member states, using figures taken from the Household Panel for 2000. The methodology is based primarily on the kernel density functions of men's and women's wages. A range of situations can be observed from the Mediterranean countries (with a smaller gender pay gap) to the very specific cases of Austria and the UK and to northern European countries where the gender pay gap is chiefly the result of a larger proportion of men at higher‐paid levels. We also offer conclusions on the relevance of public employment, part‐time employment and short‐term hiring to explain the gender wage gap in each of the countries studied.     

A Production Theory Approach to the Imports and Wage Inequality Nexus

I employ a production theory approach to investigate the effect of fluctuations in the prices of imports of different origin on the wage differential between skilled and unskilled labor in the United States. Unlike competing methodologies, the employed framework of analysis accounts for the economy-wide effects of imports that derive from both domestic output substitution as well as downstream production. The results of this study suggest that the overall impact of imports, including those that originate in less developed economies, on the wage differential is negligible. Economy-wide dynamic processes of capital accumulation and technical change appear to play a far more important role in wage dispersion.     

The Gender Wage Gap in the United States and Cross Nationally

Scholarship in sociology and economics has long explored the gender wage gap. Recent research suggests that these inequalities are indicative of important differences not only between men and women, but among women and men, reflecting rising levels of income inequality among workers in the post‐industrial era. We argue that the most interesting debates in the gender wage gap – those exploring differences among subgroups by class, race, and/or parenthood status (such as the motherhood wage penalty), as well as those considering differences across countries – can bring new insights to the study of wage inequality, as well as to understandings of what drives gendered wage inequality.     

Domestic Work and the Wage Penalty for Motherhood in West Germany

Previous research suggests that household tasks prohibit women from unfolding their full earning potential by depleting their work effort and limiting their time flexibility. The present study investigated whether this relationship can explain the wage gap between mothers and nonmothers in West Germany. The empirical analysis applied fixed‐effects models and used self‐reported information on time use and earnings as well as monthly family and work histories from the German Socio‐Economic Panel (1985–2007, N = 1,810; Wagner, Frick, & Schupp, 2007 ). The findings revealed that variation in reported time spent on child care and housework on a typical weekday explains part of the motherhood wage penalty, in particular for mothers of very young children. Furthermore, housework time incurred a significant wage penalty, but only for mothers. The authors concluded that policies designed to lighten women's domestic workload may aid mothers in following rewarding careers.     

Wage indexation: Social benefits and private incentives

The question addressed in this paper is: Do social benefits from wage indexation coincide with private incentives to incorporate COLA clauses in union contracts? In general, market forces provide an “approximately correct” solution so that legislative remedies are not required. Based on the work of Gray and Fischer, full indexation is beneficial when the economy is subjected to stochastic nominal shocks, but only partial indexation is optimal when real disturbances dominate. If unions and management of firms are risk-averse they both have an incentive to adopt full indexation when monetary uncertainty exists. On the other hand, when the economy faces real shocks, union negotiators oppose indexation if the demand for labor is elastic, but insist on full indexation if demand is inelastic. Managers of firms prefer nominal wage contracts in either case. This suggests that both parties will agree to omit COLA clauses in the first case, but are likely to compromise with partial indexation in the second case. A role for government intervention is indicated only to the extent that bargaining strength may dictate a degree of indexation that deviates from the social optimum. The analysis is extended briefly to other assumptions about the utility function of the two parties at the bargaining table.     

Examining Equality between Public- and Private-Sector Wage Distributions

Most comparability studies examine average pay differences, but this article explores differences in the distribution of public- and private-sector wages. Applying a new type of decomposition method, the results indicate that the difference in average wages is only a small part of wage incomparability, whereas differences in the variance of the differential are a much more important factor explaining incomparability. Further results find that differences in wage structure and unobservable factors determining wages have distinct effects in different parts of the wage distribution.     

Impact of the National Minimum Wage on Disabled People

The survey reported here found disparities in the impact of the introduction of the National Minimum Wage on disabled people. These were associated with age, gender, impairment and type of employment setting. The main determinant of whether individuals gained from the NMW was their status as claimants of welfare benefits. We also found evidence that paid hours had been reduced to implement the NMW with no net increase in earnings, possibly to enable people to retain benefits entitlements. We make recommendations about how the anomalies can be tackled. It may be unrealistic to expect the Act to have been implemented fully so soon after it became law and some of the anomalies found may eventually disappear. However, many of the inequalities uncovered by this survey are not addressed by the NMW, specifically those inequalities associated with impairment and gender.     

The Gender Wage Gap in Belarus

A new release of the Belarusian Household Survey on Incomes and Expenditures provides the unique opportunity for an in-depth study of the gender pay gap in Belarus. The econometric analysis involves estimates of augmented earnings equations, also corrected for sample selection bias, as well as for least absolute deviations estimates at different quantiles of the wage distribution. The results suggest that the gender wage gap is smaller than in other countries of the Commonwealth of Independent States and Central and Eastern European countries, as one would expect considering the slow transition process, and is reduced after controlling for unobservable characteristics. Moreover, the gap increases as one moves from the 10th to the 90th quantile. This means that having jobs providing generally higher levels of wages for a woman, it is more and more difficult to get the same wage as that of a man.     

How Wage Compression Affects Job Turnover

I use Swedish establishment-level panel data to test the hypothesis of Bertola and Rogerson (Eur Econ Rev 41:1147–1171 1997) of a positive relation between the degree of wage compression and job reallocation. Results indicate that the effect of wage compression on job turnover is positive and significant in the manufacturing sector. The wage compression effect is stronger on job destruction than on job creation, consistent with downward wage rigidity. Further results include a strong positive relationship between the fraction of temporary employees and job turnover and a negative relationship between the amount of working-time flexibility and job reallocation.
