Martin S. Feldstein


In addition to his wide-ranging influence within the academic and policy spheres of economics, Harvard Economics Professor Martin S. Feldstein ’61 has perhaps had his greatest impact in the classroom.

While sitting in a meeting about Social Security reform in the West Wing of the White House in 1999, Harvard Kennedy School Professor Jeffrey B. Liebman—once a Ph.D. student of Feldstein’s—realized he shared something with the others at the meeting.

“[I noticed] that three of the four economists in the room—Larry Summers, Doug Elmendorf, and myself—had been Marty’s students,” he said. “The fourth economist had studied at MIT under someone who himself had been a student of Marty’s.”

Feldstein, a professor at Harvard since 1967, has taught every level of economics, from introductory to upper-level graduate courses—training some of the world’s foremost economists in the process and spurring the Wall Street Journal to term him perhaps the “most influential economist of his generation.”

But his influence reaches far beyond Harvard. Feldstein served as the Chairman of the Council of Economic Advisers for President Ronald Reagan from 1982 to 1984 and led the National Bureau of Economic Research as its president from 1984 to 2008.


In his 21-year role as head of Harvard’s introductory economics course, Economics 10: “Principles of Economics,” Feldstein introduced hundreds of students to the discipline each year, beginning each fall with the same sentiment: “This is a particularly good year to be studying economics.”

“I always enjoyed teaching Ec 10, thinking about how to explain key issues to students with little to no background in economics,” Feldstein says.

Every year since he stopped teaching Ec 10, Feldstein has returned to Sanders Theatre to give a guest lecture on Social Security.

According to Harvard Economics Professor N. Gregory Mankiw, who took over the course from Feldstein in 2005, Feldstein never took a sabbatical in the 21 years he taught Ec 10.

“He’s a very dedicated teacher,” Mankiw says, “More dedicated than anyone I know.”

Mankiw conducted his graduate work at MIT under a professor who was a former student of Feldstein’s.

Although Feldstein now devotes all of his time in Harvard classrooms to the study of economics, as an undergraduate, Feldstein’s courses were much more diverse.

In fact, Feldstein completed the required pre-medical coursework and was debating between pursuing economics and attending medical school.

In the end, he chose economics, and in his over 40 years as a professor at Harvard, has taught students including University Professor and former University President Lawrence H. Summers, current Harvard Kennedy School Dean David T. Ellwood ’75, Columbia Business School Dean R. Glenn Hubbard, and prominent economist and Columbia University Professor Jeffrey D. Sachs ’76.
