Sir Henry Roy Forbes Harrod (13 February 1900 – 8 March 1978) was an English economist. He is best known for his biography of John Maynard Keynes and the development of the Harrod–Domar model, which he and Evsey Domar developed independently. He is also known for his International Economics, a former standard textbook, the first edition of which contained some observations and ruminations (wanting in subsequent editions) that would foreshadow theories developed independently by later scholars (such as the Balassa–Samuelson effect).
Born in London he attended St Paul's and then Westminster School. Harrod attended New College in Oxford on a history scholarship. After a brief period in the Artillery in 1918 he gained a first in "literae humaniores" in 1921, and a first in modern history the following year. Afterwards he spent some time in 1922 at King's College, Cambridge. It was there that he met and befriended Keynes.
After moving back to Oxford, he became a Student (i.e., Fellow) and Tutor in economics at Christ Church. He held the fellowship in modern history and economics until 1967. He was still in contact with Keynes and was later his biographer. He was additionally a Fellow at Nuffield College 1938 to 1947 and from 1954 to 1958.
At the 1945 General Election he stood as Liberal candidate for Huddersfield and finished third.
After retiring in 1967, he moved to Holt, Norfolk.
Interviewed for the book Authors take Sides on Vietnam, Harrod declared himself a supporter of the American military campaign in Indochina.
Contributions to Endogenous Money Theory
Although Harrod is typically remembered for his contributions to growth theory with his Harrod-Domar growth model some argue that he was the first Post-Keynesian economist to provide a detailed institutional exposition of the theory of endogenous money. In his book Money he provides a detailed institutional discussion of how the contemporary monetary system operates. He highlights, among other things: that loans create deposits; that central banks attempt to control the level of economic activity through the influence they exert on interest rates; and that central banks automatically extend funds when government borrowing puts upward pressure on interest rates. This last point discredits the mainstream views on crowding out and makes Harrod an early progenitor of the Modern Monetary Theory school of economics.
