Janet Yellen

Janet Louise Yellen, born August 13 1946, is an American economist who served as the 78th United States Secretary of the Treasury from 2021 to 2025 and previously held several prominent positions in monetary policy and economic research. Her career spans academia, federal government, and think‑tank leadership, making her a central figure in contemporary macroeconomic thought and public finance.

Early life and career

Yellen was raised in Bay Ridge, Brooklyn, a neighborhood of New York City with a strong Polish Jewish community. Her parents were Julius Yellen, a family physician, and Anna Ruth Blumenthal, an elementary school teacher who later became a stay‑at‑home mother. She has one older brother, John, who works as a program director for archaeology at the National Science Foundation. The family’s heritage traces back to Sokołów Podlaski, a town near Warsaw whose Jewish population was largely destroyed during the Holocaust.

During her secondary education, Yellen attended Fort Hamilton High School, where she distinguished herself academically and participated in various clubs, including the psychology club, history club, and the school newspaper. She earned a National Merit commendation letter and was admitted to a selective science honors program at Columbia University for Saturday mathematics studies. In 1963, she graduated as valedictorian of her high‑school class.

Yellen entered Pembroke College at Brown University with an initial interest in philosophy but switched to economics during her freshman year. Influenced by professors George Herbert Borts and Herschel Grossman, she completed a Bachelor of Arts in economics summa cum laude and Phi Beta Kappa in 1967. She then pursued graduate studies at Yale University, earning both a master’s degree and a Ph.D. in economics in 1971. Her dissertation, supervised by James Tobin—a future Nobel laureate—examined employment, output, and capital accumulation in an open economy through a disequilibrium lens.

After completing her doctorate, Yellen began her academic career as an assistant professor of economics at Harvard University (1971–1976). At that time, she was one of only two female faculty members in the department. She later worked as a staff economist for the Federal Reserve Board (1977–1978) and served on the faculty of the London School of Economics (1978–1980).

In 1980, Yellen joined the University of California, Berkeley, where she has remained a faculty member ever since. She holds the Eugene E. and Catherine M. Trefethen Professorship in Business Administration and Economics at UC Berkeley’s Haas School of Business and is professor emeritus there. Her long tenure at Berkeley has been marked by significant contributions to macroeconomic theory, particularly in the areas of monetary policy, employment dynamics, and international economics.

Cabinet tenure

Yellen’s first major federal appointment came when President Bill Clinton nominated her to serve on the Federal Reserve Board of Governors (1994–1997). She later became Chair of the White House Council of Economic Advisers under the same administration (1997–1999), where she advised on national economic policy.

After a period in academia, Yellen returned to public service as President and Chief Executive Officer of the Federal Reserve Bank of San Francisco (2004–2010). In 2010, President Barack Obama appointed her Vice Chair of the Federal Reserve Board, a position she held until 2014. Three years later, she was nominated by President Obama to succeed Ben Bernanke as Chair of the Federal Reserve, becoming the first woman to hold that office. Her tenure as Chair (2014–2018) included navigating the economy through the aftermath of the global financial crisis and implementing monetary policy adjustments.

Following her service at the Fed, Yellen joined the Brookings Institution as a distinguished fellow in residence from 2018 until early 2020. In November 2020, President‑elect Joe Biden nominated her to serve as Secretary of the Treasury. The United States Senate confirmed her appointment on January 25 2021, and she was sworn into office by Vice President Kamala Harris the following day. Yellen served as Treasury Secretary from 2021 until 2025, overseeing federal fiscal policy, financial regulation, and international economic relations.

Legacy

Janet Yellen’s career is distinguished by several firsts: she became the first woman to serve as Chair of the Federal Reserve and the first woman to hold the position of United States Secretary of the Treasury. Her academic work has influenced both theoretical and applied macroeconomics, with a particular emphasis on monetary policy frameworks, labor market dynamics, and international capital flows.

In public service, Yellen’s leadership roles placed her at the center of critical economic decision‑making during periods of significant change, including the recovery from the 2008 financial crisis and the early stages of the COVID‑19 pandemic. Her tenure as Treasury Secretary involved managing fiscal responses to unprecedented economic challenges and coordinating with international partners on monetary policy and trade issues.

Beyond her formal positions, Yellen has been a prolific scholar and educator. Her long association with UC Berkeley’s Haas School of Business has produced numerous students who have gone on to influential roles in academia, government, and the private sector. She has also contributed to public discourse through research publications, policy briefs, and participation in national economic forums.

Yellen’s legacy is characterized by a blend of rigorous academic inquiry and practical policymaking experience. Her contributions continue to shape contemporary discussions on monetary policy, fiscal responsibility, and global economic cooperation.
