Clark A. Warburton, 83, an economist with the Federal Deposit Insurance Corporation from 1934 until 1965, died Tuesday at Fairfax Hospital after a heart attack. He lived in McLean.

He became chief of the banking and business section of the division of research and statistics at FDIC in 1953, and held that position until retiring in 1965.

In 1962, Dr. Warburton took a leave of absence from the FDIC to serve on the staff of the House Banking and Currency Committee. Before joining the FDIC, he had been a member of the research staff at the Brookings Institution for two years and was co-author of "America's Capacity to Consume."

Dr. Warburton was known for his contributions toward furthering American scholarship in monetary economics. Calling these contributions "significant," the noted economist and educator, Paul McCracken, wrote of Dr. Warburton in 1965:

"The field of economic policy has been particularly benefited by his insistent attention to the role of money and monetary and credit policy in explaining economic developments. I believe it is not an exaggeration to say that the highly important scholarly work of Dr. Clark Warburton was the single most important factor drawing the attention of economists generally to these important matters."

Dr. Warburton was born near Ithaca, N.Y. He served with the American Expeditionary Force in France in World War I after attending Houghton College in New York.

After the war, he earned bachelor's and master's degrees from Cornell University and later received a doctorate from Columbia University.

Before joining the federal government, he taught at Ewing Christian College and the University of Allahabad in India, Emory University, Rice Institute, Michigan State University, the University of Virginia and the University of California at Davis.

Dr. Warburton was a member of Phi Beta Kappa, the American Economics Association, the Southern Economic Association and the Cosmos Club. He was the author of three books and numerous articles in his field.

He is survived by a son, Peter, of Sunnyvale, Calif., and two grandchildren. His wife, the former Amber Arthun, died three years ago.
