The Gender Wage Gap in New York State and Its Solutions
by Ariane Hegewich, Jeff Hayes, Ph.D., Heidi Hartmann, Ph.D., Jocelyn Fischer, Claudia Williams, and Justine Augeri (December 2011)

This gender wage gap has pernicious consequences for women and their families. 14.8 percent of women in New York State had incomes at or below the official poverty threshold (for families of their size and composition). This poverty rate for women in New York is approximately the same as that for women in the United States as a whole, with 28 states having less female poverty than New York State.


Retirement on the Edge: Women, Men, and Economic Insecurity After the Great Recession
by Cynthia Hess, Ph.D., Jeff Hayes, Ph.D. and, Heidi Hartmann, Ph.D. (September 2011)

The IWPR/Rockefeller Survey addressed the extent of economic security almost a year and a half after the recession officially ended. Many of the survey’s findings are detailed in the report, Women and Men Living On the Edge: Economic Insecurity After the Great Recession (Hayes and Hartmann 2011). This report analyzes a specific aspect of the IWPR/Rockefeller Survey’s findings: issues related to retirement security following the recession. It finds that men and women after the Great Recession experience uncertainty about the adequacy of their financial resources for the proverbial “golden years,” an uncertainty that may shape how they view the meaning of retirement and their own decisions about the future.

Women and Men Living on the Edge: Economic Insecurity After the Great Recession
by Jeffrey Hayes, Ph.D. and Heidi Hartmann, Ph.D. (September 2011)

The IWPR/Rockefeller Survey of Economic Security, like several other recent surveys, finds that the effects of the 2007–2009 recession, known as the Great Recession, are both broad and deep. The IWPR/Rockefeller survey shows that more than one and a half years after the recession came to an official end, and the recovery supposedly began, many women and men report that they are still suffering significant hardships. They are having difficulty paying for basics like food (26 million women and 15 million men), health care (46 million women and 34 million men), rent or mortgage (32 million women and 25 million men), transportation (37 million women and 28 million men), utility bills (41 million women and 27 million men), and they have difficulty saving for the future (65 million women and 53 million men). On almost every measure of insecurity and hardship the survey reveals the Great Recession has visited more hardship on women than it has on men.

Latinas and Social Security
by Jeffrey Hayes, Ph.D., Youngmin Yi, and Heather Berg (April 2011)

Social Security is a crucial source of income for many Americans. This is particularly true for women and people of color, who tend to have fewer alternative sources of income, experience higher poverty rates, and earn less on average throughout their working years (Hartmann, Hayes, and Drago 2011).

Social Security: Especially Vital to Women and People of Color, Men Increasingly Reliant

Better Health for Mothers and Children: Breastfeeding Accommodations under the Affordable Care Act
by Robert Drago, Ph.D., Jeffrey Hayes, Ph.D., and Youngmin Yi (December 2010)

This study examines new workplace protections for nursing mothers under federal law. We report current patterns of breastfeeding, and provide the first estimates of coverage rates under the law, as well as the first projections of the likely effect of the new protections on increasing rates of breastfeeding in the United States. The research represents part of a broader body of work undertaken by the Institute for Women’s Policy Research on balancing work and family commitments. The research was made possible by grants from the Annie E. Casey Foundation, the Ford Foundation, the Kellogg Foundation, and the Rockefeller Foundation.

Separate and Not Equal? Gender Segregation in the Labor Market and the Gender Wage Gap
by Ariane Hegewisch, Hannah Leipmann, Jeffrey Hayes, and Heidi Hartmann (September 2010)


Separate and Not Equal? Gender Segregation in the Labor Market and the Gender Wage Gap
by Ariane Hegewisch, Hannah Liepmann, Jeffrey Hayes, and Heidi Hartmann (August 2010)

Occupational gender segregation is a strong feature of the US labor market. While some occupations have become increasingly integrated over time, others remain highly dominated by either men or women. Our analysis of trends in overall gender segregation shows that, after a considerable move towards more integrated occupations in the 1970s and 1980s, progress has completely stalled since the mid 1990s. Occupational segregation is a concern to policy makers for two reasons: it is inefficient economically, preventing able people from moving into occupations where they could perform well and that would satisfy them more than the ones open to them. And occupational segregation is a major cause for the persistent wage gap. Our analysis confirms that average earnings tend to be lower the higher the percentage of female workers in an occupation, and that this relationship is strongest for the most highly skilled occupations, such as medicine or law. Yet this is also a strong feature of jobs requiring little formal education and experience, increasing the likelihood of very low earnings for women working in female-dominated, low-skilled occupations such as childcare.

Are Women Now Half the Labor Force? The Truth about Women and Equal Participation in the Labor Force
by Ashley English, Heidi Hartmann, PhD, and Jeff Hayes (March 2010)

For more than a year the news media have been tracking the moment when women might become half the labor force. In spring 2009, it was said it might happen in the next few months, by summer it was said maybe it would happen in the fall. By one measure, women’s share of employment reached a high of 49.96 percent in October 2009; still 113,000 fewer women than men were counted on payrolls that month, and as of March 2010 the gap has grown to about 360,000 workers. Although still a statistically significant difference, a gap that small is nevertheless close to equality, especially when total payroll employment in the United States is measured at nearly 130,000,000.
