Career

Border received a bachelor's degree in economics from Caltech in 1974. Shortly after completing his Ph.D. in economics at the University of Minnesota in 1979, he returned to Caltech as a faculty member, where he remained for over forty years.^[1]

Border specialized in decision theory and auction design. In 1991, he proved a set of inequalities (now known as Border's theorem) that characterize the possible allocations for a single-item auction,^[3] a result that now plays a key role in the computational design of auctions.^[4] He also contributed several applications of Arrow's impossibility theorem to economic domains.^[5]

Border was also known for his teaching in subjects of mathematical economics, and for his extensive in-depth lecture notes.^[6]

Personal life

Border died on November 19, 2020, and is survived by his son.^[1]
