不對，你還是查一下。 他從本科到博士都是經濟學，紐約大學。

Greenspan attended George Washington High School from 1940 until he graduated in June 1943, where one of his classmates was John Kemeny.^[13] He played clarinet and saxophone along with Stan Getz. He further studied clarinet at the Juilliard School from 1943 to 1944.^[14] Among his bandmates in the Woody Herman band was Leonard Garment, Richard Nixon's Special Counsel. In 1945, Greenspan attended New York University's Stern School of Business, where he earned a B.A. degree in economics summa cum laude in 1948^[15] and an M.A. degree in economics in 1950.^[16] At Columbia University, he pursued advanced economic studies under Arthur Burns but dropped out.^[17]

In 1977, Greenspan obtained a Ph.D. in economics from New York University. His dissertation is not available from the university^[18] since it was removed at Greenspan's request in 1987, when he became Chairman of the Federal Reserve Board. In April 2008, however, Barron's obtained a copy and notes that it includes "a discussion of soaring housing prices and their effect on consumer spending; it even anticipates a bursting housing bubble".^[19]
