Occupational Gender Composition and Wages in Canada: 1987-1988

The relationship between occupational gender composition and wages is the basis of pay equity/comparable worth legislation. A number of previous studies have examined this relationship in US data, identifying some of the determinants of low wages in ``female jobs'' well as important limitations of public policy in this area. There is little evidence, however, from other jurisdictions. This omission is particularly disturbing in the case of Canada, which now has some of the most extensive pay equity legislation in the world. In this paper we provide a comprehensive picture, circa the late 1980's, of the occupational gender segregation in Canada and its consequences for wages. The sample period precedes many provincial pay equity initiatives and thus the results should provide a baseline for the evaluation of this legislation. We find that the estimated wage penalties in female jobs in Canada are generally much smaller than the estimates for the United States. Although there is some heterogeneity across worker groups on average, the link between female wages and gender composition is small and not statistically significant.

Does Comparable Worth Work in a Decentralized Labor Market?

We investigate the effect of pro-active comparable worth legislation---covering both the public and private sectors---on wages, the gender wage gap and the gender composition of employment. The focus is the pay equity initiative of the Canadian province of Ontario in the early 1990s. We document substantial lapses in compliance and problems with the implementation of the law among smaller firms where the majority of men and women work. This evidence provides important lessons of the obstacles to extending pay equity to the private sector of a decentralized labor market. When we focus on those sectors of the labor market where compliance was relatively strict, our results suggest that any positive effects on the wages of women in female jobs were very modest. Our most consistently estimated effects of the law on wages are negative: slower wage growth for women in male jobs and for men in female jobs.

Gender Composition and Wages: Why is Canada different from the United States?

The correlation of occupational gender composition and wages is the basis of pay equity/comparable worth legislation. A number of previous studies have examined this correlation in US data, identifying some of the determinants of low wages in ``female jobs'', as well as important limitations of public policy in this area. There is little evidence, however, from other jurisdictions. This omission is particularly disturbing in the case of Canada, which now has some of the most extensive pay equity legislation in the world. In this paper, we provide a comprehensive picture, circa the late 1980's, of the occupational gender segregation in Canada and its consequences for wages. We also draw explicit comparisons of our findings to evidence for the United States. We find that the link between female wages and gender composition is much stronger in the United States than in Canada, where it is generally small and not statistically significant. The relatively more advantageous position of women in female jobs in Canada is found to be linked to higher unionization rates and the industry-wage effects of ``public goods'' sectors.

Women's Wages in Women's Work: A US/Canada Comparison of the Roles of Unions and Public Goods Sector Jobs

In this paper, we investigate the mechanism by which the femaleness of occupations has a negative effect on women's wages. We relate US/Canada differences in labor market institutions, the returns to skills and other dimensions of the wage structure, such as occupational rents, to corresponding differences in the rewards to female jobs. Our analysis, which uses US data from the CPS-ORG for 1988 and Canadian data from the 1988 LMAS, uncovers intriguing US/Canada differences in the effect of occupational gender composition on women's wages. The estimated effect for Canadian women is generally small and not statistically significant, while estimates for American women are relatively large and comparable to the evidence in previous studies. Relating these differences to cross-country variation in other wage determinants reveals that higher rates of unionization, and the higher occupation wage effects for certain public good sector jobs such as educational services, work to the advantage of Canadian women. We also find that the relatively higher pay of integrated jobs in the United States helps account for the larger negative effect of gender composition on women's wages in this country. Dans cet article, nous étudions le mécanisme par lequel le taux de féminité des occupations peut avoir un effect négatif sur les salaires des femmes. Nous utilisons une comparaison internationale États-Unis/Canada pour relier les différences institutionnelles du marché du travail, les différences dans les rendements des qualifications et dans d'autres dimensions de la structure salariale, comme les rentes occupationnelles, à des différences dans la rémunération des emplois à prédominance féminine. Notre analyse, qui utilise les données américaines provenant des CPS-ORG pour 1988 et les données canadiennes provenant de l'enquête sur l'activité aussi pour 1988, démontre l'existence de différences intéressantes entre les États-Unis et le Canada quant à l'effet du taux de féminité des occupations sur les salaires des femmes. L'effet estimé pour les canadiennes, dans leur ensemble, est généralement petit et n'est pas statistiquement significatif, alors que l'effet estimé pour les américaines est relativement important et comparable aux résultats des études antérieures. Lorsque nous relions ces différences internationales aux autres déterminants de la structure salariale, nous trouvons que les taux de syndication relativement élevés, et les effets fixes relativement élevés des occupations procurant des biens publics sont à l'avantage des canadiennes. Nous trouvons aussi que les salaires relativement plus élevés des occupations intégrées aux États-Unis contribuent à l'effet négatif du taux de féminité des occupations sur les salaires des femmes dans ce pays.Pay equity, comparable worth, public sector jobs, gender composition, cross-country comparison, Équité salariale, salaire égal pour travail de valeur comparable, taux de féminité occupationnel, emplois publics, syndicats, comparaisons internationales

Does Comparable Worth Work in a Decentralized Labor Market?

We investigate the effect of pro-active comparable worth legislation covering both the public and private sectors on wages, the gender wage gap and the gender composition of employment. The focus is the pay equity initiative of the Canadian province of Ontario in the early 1990s. We document substantial lapses in compliance and problems with the implementation of the law among smaller firms where the majority of men and women work. This evidence provides important lessons of the obstacles to extending pay equity to the private sector of a decentralized labor market. When we focus on those sectors of the labor market where compliance was relatively strict, our results suggest that any positive effects on the wages of women in female jobs were very modest. Out most consistently estimated effects of the law on wages are negative: slower wage growth for women in male jobs and for men in female jobs. Dans cet article, nous étudions les effets d'une loi d'équité salariale proactive, qui s'applique à la fois au secteur public et au secteur privé, sur les salaires, le rapport entre le salaire moyen des femmes et des hommes et la féminité des emplois. Cette initiative législative a été mise en oeuvre dans la province canadienne de l'Ontario au début des années quatre-vingt-dix. Nous documentons plusieurs défaillances dans le respect de la loi, ainsi que les problèmes d'implémentation de la loi dans les petites et moyennes entreprises qui emploient une majorité d'hommes et de femmes. Cela nous permet de tirer des leçons importantes quant aux obstacles rencontrés dans l'application de l'équité salariale dans une économie décentralisée. Lorsque nous nous concentrons sur les secteurs du marché du travail où la loi a été le plus respectée, nos résultats indiquent que les effets positifs sur les salaires des femmes occupant des emplois féminins sont très minces. Nos résultats les plus robustes quant aux effets de la loi sur les salaires sont plutôt négatifs: celle-ci aurait ralenti la croissance des salaires des femmes occupant des emplois masculins et des hommes occupant des emplois féminins.Pay equity, comparable worth, pro-active pay equity plans, Ontario, enforcement and compliance, Équité salariale, salaire égal pour travail de valeur comparable, programmes d'équité pro-actifs, Ontario, mise en vigueur et respect des lois

Early- and late-migrating cranial neural crest cell populations have equivalent developmental potential in vivo

We present the first in vivo study of the long-term fate and potential of early-migrating and late-migrating mesencephalic neural crest cell populations, by performing isochronic and heterochronic quail-to-chick grafts. Both early- and late-migrating populations form melanocytes, neurons, glia, cartilage and bone in isochronic, isotopic chimeras, showing that neither population is lineage-restricted. The early-migrating population distributes both dorsally and ventrally during normal development, while the late-migrating population is confined dorsally and forms much less cartilage and bone. When the late-migrating population is substituted heterochronically for the early-migrating population, it contributes extensively to ventral derivatives such as jaw cartilage and bone. Conversely, when the early-migrating population is substituted heterochronically for the late-migrating population, it no longer contributes to the jaw skeleton and only forms dorsal derivatives. When the late-migrating population is grafted into a late-stage host whose neural crest had previously been ablated, it migrates ventrally into the jaws. Thus, the dorsal fate restriction of the late-migrating mesencephalic neural crest cell population in normal development is due to the presence of earlier-migrating neural crest cells, rather than to any change in the environment or to any intrinsic difference in migratory ability or potential between early- and late-migrating cell populations. These results highlight the plasticity of the neural crest and show that its fate is determined primarily by the environment

Procarbazine and antidepressants: a retrospective review of the risk of serotonin toxicity

Background Procarbazine is an anticancer agent that also inhibits monoamine oxidase, an enzyme responsible for the metabolism of various catecholamines, including serotonin. Methods A retrospective chart review of lymphoma patients who were treated with both procarbazine and an antidepressant, as well as procarbazine alone, was performed to determine if signs and symptoms of serotonin toxicity were present. Results A total of 65 patients received procarbazine between 2004 and 2010 and were eligible to be included in the study. Twenty‐six of these patients received an antidepressant in combination with procarbazine, with selective serotonin reuptake inhibitors being the most common type of antidepressant. No patients in the study were diagnosed with serotonin toxicity, nor did any meet Hunter's diagnostic criteria for serotonin toxicity. Diarrhea, tremor, and shivering were the symptoms from Sternbach's criteria that were further analyzed, with diarrhea occurring 8.54% of the time, tremor occurring 5.53% of the time, and shivering occurring 2.51% of the time in patients who received an antidepressant with their procarbazine. Despite these symptoms, the diagnosis of serotonin toxicity according to Sternbach's criteria was determined to be unlikely. Conclusions In this small sample of patients treated with procarbazine plus an antidepressant (most typically SSRIs), there were no reports of serotonin toxicity, nor did any patients demonstrate symptoms consistent with serotonin toxicity. The authors urge clinicians to ensure depression is adequately managed in cancer patients who are undergoing procarbazine therapy, starting with typical first‐line antidepressant agents.

A Multi-Proxy Approach to Archaeobotanical Research: Archaic and Fremont Diets, Utah

New analytical techniques in archaeobotany allow researchers to examine human plant use by developing interrelated, yet independent lines of evidence. Here we outline the results of a two-method archaeobotanical approach to investigate Archaic and Fremont Great Basin diets. We conducted both macro- and microbotanical (starch granule) analyses at nine archaeological sites located in central and southwestern Utah. Our results show that in contexts where macrobotanical remains are poorly preserved, the application of microbotanical methods can produce additional sets of information, thus improving interpretations about past human diets. In this study, macrobotanical remains represented seed-based dietary contributions, while microbotanical remains came primarily from geophytes. Results suggest largely overlapping diets for Archaic and Fremont residents of Utah
