In 1975, Milgrom enrolled for graduate studies at Stanford University in the MBA program. After his first year, he was invited to the Ph.D. program,[citation needed] earning an MS in statistics in 1978 and a PhD in business in 1979.[5] His dissertation on the theory of auctions (Milgrom, 1979a) won the Leonard Savage prize.[citation needed] This also led to the first of seminal articles on auction theory (Milgrom, 1979b). His thesis advisor, Robert B. Wilson, would later become his collaborator in designing the spectrum auction used by the Federal Communications Commission.
