David Cooper

Director of the Economic Analysis and Research Network (EARN)

Some of the most innovative and consequential policymaking happens at the state and local level, and we have to make sure that policymakers at every level of government are doing what’s best for working people, and prioritizing anti-racist, equity-promoting policies. EARN’s impeccable research and strong partnerships with grassroots allies are critical to that achieving that goal.”

Biography

David Cooper is director of the Economic Analysis and Research Network (EARN), a national network of nearly 60 state- and local-level policy research and advocacy organizations coordinated by the Economic Policy Institute. He assumed the leadership of EARN in October 2021, after serving as senior economic analyst and EARN deputy director. As EARN director, Cooper works to expand the network’s reach and deepen its impact by strengthening partnerships between EARN groups and grassroots organizations, labor unions, and community advocates. He also works to expand EARN groups’ ability to provide rigorous analysis that centers people of color and is grounded in the real-world experiences of workers and families.

In his time with EARN, Cooper has overseen a vast expansion in the program’s research and analytical capacities and a more explicit focus on the experience of Black and Brown workers—building up the data, research, and policy resources available to support EARN groups’ worker, racial, and gender justice work. He has guided EARN’s creation of new training programs, workshop series, state-level data tools, and a robust technical assistance infrastructure to assist policy researchers and advocates throughout the country. With support from the EARN team at EPI, EARN groups have shaped numerous state and local policy debates, providing timely and credible analyses that have helped secure critical pro-worker, equity-promoting policy reforms, such as higher minimum wages, expanded access to overtime, paid leave benefits, fair scheduling protections, and stronger collective bargaining rights.

As part of EPI’s research team, Cooper’s work on the minimum wage, wage theft, social insurance, and state labor markets has been used by policymakers in city halls and statehouses across the country, as well as in Congress and the White House. His analyses on the impact of minimum wage laws have been instrumental in dozens of state and local minimum wage debates since 2011. He has testified in many states and cities on the challenges low-wage workers and low-income families face.

Cooper has been interviewed and cited by numerous media, including the New York Times, Washington Post, and Wall Street Journal. He has appeared on many local and national news programs, including the Public Broadcasting Service’s “NewsHour,” CNBC’s “Closing Bell,” National Public Radio’s “All Things Considered,” and American Public Media’s ”Marketplace.”

Heidi Shierholz

President

Since its founding, EPI has highlighted how rising inequality, wage stagnation, and an expanding Black–white wage gap are not ‘natural’ phenomena, but are the result of deliberate policy choices shifting power from workers to the wealthy. Through its research and expertise, EPI has the opportunity to advance real reforms that lead to economic justice, racial justice, and gender equity.”

 

 

Biography

Heidi Shierholz (she/her) is the president of the Economic Policy Institute, a nonprofit, nonpartisan think tank that uses the power of its research on economic trends and on the impact of economic policies to advance reforms that serve working people, deliver racial justice, and guarantee gender equity. In 2021 she became the fourth president EPI has had since its founding in 1986.

Shierholz, who served the Obama administration as chief economist at the Department of Labor, has been a consistent and leading voice for a worker-centered policy agenda that prioritizes economic and racial justice. Taking the helm at EPI after former President Thea Lee departed to work for the Biden administration, Shierholz is strengthening EPI’s ability to deliver economic analysis that challenges and transforms the mainstream narrative about the economy. Under her leadership, EPI is focused on fighting for and winning federal, state, and local legislative and regulatory reforms that support collective bargaining; increase worker power; improve wages, benefits, and working conditions; and reduce racial and gender inequities.

 

Shierholz testifying before the Senate on the importance of unions to racial justice

As EPI policy director from 2017 to 2021, Shierholz led a significant expansion of EPI’s federal policy work, using deeply credible economic research and analysis to build power for working people. Research and insights from EPI on labor and employment policy, wage stagnation, unions, inequality, unemployment benefits, and the policies needed to generate a strong and equitable recovery from the COVID-19 recession routinely shaped policy proposals and informed economic news coverage.

As chief economist at the Department of Labor from 2014 to 2017, Shierholz developed and executed initiatives to boost workers’ rights, wages, and benefits. During her term, the Labor Department became a focal point for ambitious economic policies, such as new regulations guaranteeing overtime pay for millions of workers.

A labor market economist who holds a Ph.D. in economics from the University of Michigan, Shierholz was tapped in 2007 by then EPI President Larry Mishel to join EPI as a labor economist, a role she held until joining the Obama administration in 2014. Prior to joining EPI in 2007, Shierholz was assistant professor of economics at the University of Toronto.

Throughout her career, Shierholz has educated policymakers, journalists, partner organizations, and the public about the effects of economic policies on low- and middle-income families. A frequent expert witness before congressional committees and public commentator on major media outlets, Shierholz was named one of Washington’s most influential people outside of government by Washingtonian Magazine in 2021. Her work has been cited in many news outlets, including NBC Nightly News, CBS Evening News, The Today Show, MSNBC, CNN, CNBC, CSPAN, Fox Business, Bloomberg, NPR, PRI, New York Times, Washington Post, Wall Street Journal, and Los Angeles Times.

From C-SPAN to the halls of Congress, Shierholz showcases impactful moments where our voice is heard, making strides for the change we believe in. Media Inquiries: news@epi.org.

A consistent theme throughout Shierholz’s career has been the research showing that unions are a critical force for equality and racial economic justice in this country.

“All workers get a boost from being in unions … but Black workers and Hispanic workers get a bigger boost from being in unions than white workers do,” Shierholz explained to a congressional committee in 2021. “If we take seriously this discussion we are having about racial economic justice, a really important thing we have to do there is boost unionization.”

In addition, she led the creation of a new Worker Power initiative focused on expanding the ability of working people to achieve justice through organizing, collective bargaining, and enacting state and local policies that ensure all workers have the freedom to join together in a union and gain a voice on the job.  

Before joining EPI, Walker served as assistant to the president at the American Federation of State, County and Municipal Employees (AFSCME), where she coordinated AFSCME’s partnerships with allies and coalitions to build power for working families.
