Julio Rotemberg, the William Ziegler professor of business administration at Harvard Business School died April 2, 2017, of cancer. He was 63.

Rotemberg earned a bachelor’s degree in economics from the University of California, Berkeley, in 1975. In 1981 he earned a Ph.D. degree in economics from Princeton. From 1980 to 1996, he was on the faculty of the MIT Sloan School of Management. He joined the Harvard faculty full time in 1997.

Rotemberg was a pioneering and influential economist who developed an econometric approach to modeling the economy. He published more than 50 articles, papers, and book chapters on economic fluctuations, especially the effects of monetary and fiscal policies. In 2016, the American Economics Association honored him with its Distinguished Fellows Award.

The dean of Harvard Business School, Nitin Nohria, stated, “Julio Rotemberg was a superb scholar and beloved teacher who left a lasting mark on the field of economics and on thousands of students.” Former Harvard President Lawrence H. Summers added, “In a University full of extraordinary talents, Julio was truly one of a kind. … Above all, I’ll miss our intellectual companionship.”

Rotemberg is survived by his wife, Analisa Lattes; their two children; and his mother, Ellen Wolf, of Argentina.
