A professor of economics at Stanford University and fellow at its Hoover Institution, John B. Taylor has made influential contributions in monetary policy, public service, and academia for five decades. A Celebration Honoring John B. Taylor's Contributions to Economics and Monetary Policy is based on a conference held May 8, 2025, at the Hoover Institution to honor Taylor and his career. Many of Taylor's colleagues, students, and friends came together to pay tribute and share insightful anecdotes of his character and dedication. Reflecting the conference proceedings, this volume shares the presentations and vivid discussions around Taylor's role as a leading economist, from his development of the influential Taylor rule—an important tool of monetary policy—to his laudable public service in the US Treasury and on the Council of Economic Advisers under three presidents. The impact of Taylor's work is enhanced by his deep policy engagement. This volume further captures how Taylor's influence extended through personal interactions with colleagues and generations of students.
