by Heidi Hartmann, Ph.D. (January 2014)

IWPR President Heidi Hartmann's testimony on equal pay and the minimum wage before the House Democratic Steering and Policy Committee for the hearing, "When Women Succeed, America Succeeds: Moving Forward on the Five-Year Anniversary of Lilly Ledbetter Fair Pay Act," held on January 29, 2014.


Pay Secrecy and Wage Discrimination
by Institute for Women's Policy Research (January 2014)

About half of all workers (51 percent of women and 47 percent of men) report that the discussion of wage and salary information is either discouraged or prohibited and/or could lead to punishment. Most government agencies have formal grade and step systems that make general wage and salary information public (only 18 percent of women and 11 percent of men in the public sector report discouragement or prohibition of wage and salary discussions).


How Equal Pay for Working Women would Reduce Poverty and Grow the American Economy
by Heidi Hartmann, Ph.D., Jeffrey Hayes, Ph.D., and Jennifer Clark (January 2014)

Persistent earnings inequality for working women translates into lower pay, less family income, and more poverty in families with a working woman, which is of no small consequence to working families. About 71 percent of all mothers in the United States work for pay. Of these, about two-thirds (68 percent) are married and typically have access to men’s incomes, but married women’s earnings are nevertheless crucial to family support. One-third (32 percent) are single mothers and often the sole support of their families. And many without children, both single and married, work to support themselves and other family members. This briefing paper summarizes analyses of the 2010-2012 Current Population Survey Annual Social and Economic supplement and uses statistical controls for labor supply, human capital, and labor market characteristics to estimate: 1) how much women’s earnings and family incomes would rise with equal pay; 2) how much women and their families lose because women earn less than similarly qualified men; and 3) how much the economy as a whole suffers from inequality in pay between women and men.


Job Growth Slows in December: Women Gained All 74,000 Jobs Added to Payrolls
by Institute for Women's Policy Research (January 2014)

According to an Institute for Women’s Policy Research (IWPR) analysis of the January employment report from the U.S. Bureau of Labor Statistics (BLS), women gained 75,000 jobs added to nonfarm payrolls in December while men lost 1,000 for a net increase of 74,000 jobs in December. Because women continued to add jobs in the past month, as of December, women hold more jobs on payrolls than ever. Men have regained 75 percent (4.5 million) of the jobs they lost between December 2007 and the trough for men’s employment in February 2010 (6 million). The gap between women’s and men’s employment is 1.5 million jobs in December, substantially less than at the start of the recession (3.4 million jobs in December 2007).

How Education Pays Off for Older Americans
by Heidi Hartmann, Ph.D. and Jeff Hayes (December 2013)

This report presents findings from an Institute for Women’s Policy Research (IWPR) analysis of the 2005-2009 American Community Survey data regarding the earnings of older men and women with different levels of education. The analysis was funded by the Alfred P. Sloan Foundation, and is part of IWPR’s on-going research concerning the economic status and security of older women and men.


Valuing Good Health in Newark: The Costs and Benefits of Earned Sick Time
by Claudia Williams, Susan Andrzejewski, and Jeff Hayes, Ph.D. (December 2013)

This briefing paper uses data collected by the U.S. Bureau of Labor Statistics, the Centers for Disease Control and Prevention, the New Jersey Department of Health, and the U.S. Census Bureau to evaluate costs and benefits of Newark’s Worker Sick Leave Ordinance. It estimates how much time off Newark workers would use under the proposed policy and the costs to employers for that earned sick time. This analysis also uses findings from previous peer-reviewed research to estimate cost-savings associated with the proposed policy, through reduced turnover, reduced spread of contagious disease in the workplace, prevention of productivity losses from employees working while sick, minimized nursing-home stays, and reduced norovirus outbreaks in nursing homes. The study is one of a series of analyses by IWPR examining the effects of earned sick day policies.


Job Growth Continues with 203,000 Jobs Added in November
by Institute for Women's Policy Research (December 2013)

According to an Institute for Women’s Policy Research (IWPR) analysis of the December employment report from the U.S. Bureau of Labor Statistics (BLS), of the 203,000 total jobs added to nonfarm payrolls in November, women gained 94,000 of those jobs (46 percent) while men gained 109,000 jobs (54 percent).


Access to Earned Sick Days in Eugene, Oregon
by Claudia Williams. (December 2013)

An analysis by the Institute for Women’s Policy Research (IWPR) reveals that about 25,310 or 51 percent of private sector employees in Eugene, Oregon lack even a single earned sick day off. Access to earned sick days promotes healthy work environments by reducing the spread of illness, increasing productivity, and supporting work and family balance. Earned sick days allow people to take time off work to recover from illness and to tend to family members’ health without the fear of lost pay or other negative consequences. This briefing paper presents estimates of lack of earned sick days access rates in Eugene, Oregon by sex, and personal annual earnings, and in Oregon by race and ethnicity through analysis of government data sources, including the National Health Interview Survey (NHIS) and the American Community Survey (ACS).


Accelerating Change for Women Faculty of Color in STEM: Policy, Action, and Collaboration
by Cynthia Hess, Ph.D., Barbara Gault, Ph.D., and Youngmin Yi (November 2013)

This report is part of a project to address the underrepresentation of women faculty of color in science, technology, engineering, and mathematics (STEM) led by the Institute for Women’s Policy Research (IWPR). It summarizes highlights from a convening held in May 2013 that brought together nearly 50 experts, including professors, academic administrators, and representatives of government, professional societies, the corporate sector, and women’s organizations. It addresses the barriers that make it difficult for women faculty of color to advance in STEM fields, key programmatic and policy shifts that would promote their success, and strategies for implementing promising changes and taking them to scale. The convening and report are part of IWPR’s research on education and training, which includes early care and education, girls’ experiences in the K-12 system, postsecondary attainment, and high-quality workforce development opportunities for STEM and other careers. IWPR’s recent research in this area includes a profile of programs at community colleges designed to engage women in STEM fields, as well as reports exploring pedagogical methods to increase women’s participation in engineering.

Women and Men in the Recovery: Where the Jobs Are; Women’s Recovery Strengthens in Year Four
by Heidi Hartmann, Ph.D., Elyse Shaw, and Elizabeth Pandya (November 2013)

While the number of jobs dropped steeply, particularly for men, in the Great Recession, slow job growth has characterized much of the recovery. In the first two years of the recovery men saw faster job growth than women. In the third year of recovery, women's job growth saw pronounced gains and had largely caught up to men's. Strong gains continued for women into the fourth year of recovery where, overall, the percentage of job’s recovered for women surpassed that of men’s. As of June 2013, men had regained 68 percent of the jobs they lost in the recession and women had regained 91 percent of the jobs they lost.


Expanding Social Security Benefits for Financially Vulnerable Populations
by Older Women's Economic Security (OWES) Task Force of the National Council of Women's Organizations and Center for Community Change (October 2013)

Social Security benefits are especially important to populations that experience greater economic insecurity as they age — particularly women, people of color, and same-sex couples. These populations are often disadvantaged both as workers and consumers, which contributes to their increased financial vulnerability in retirement. Social Security, from the beginning, has included features that partially offset the effects of workplace disadvantages. This legacy should be built upon by the enactment of the modest changes proposed in this white paper. This paper outlines five key policy changes that would help to build upon our Social Security system and help to make sure that it functions even better for women, samesex spouses, and low-income people.
