Robert Merton Solow (born August 23, 1924) is an American economist particularly known for his work on the theory of economic growth that culminated in the exogenous growth model named after him. He was awarded the John Bates Clark Medal (in 1961) and the 1987 Nobel Memorial Prize in Economic Sciences.
Robert Solow was born in Brooklyn, New York in a Jewish family on August 23, 1924, the oldest of three children. He was well educated in the neighborhood public schools of New York City and excelled academically early in life. In September 1940, Solow went to Harvard College with a scholarship at the age of 16. At Harvard, his first studies were in sociology and anthropology as well as elementary economics.
By the end of 1942, Solow left the university and joined the U.S. Army. He served briefly in North Africa and Sicily, and later served in Italy during World War II until he was discharged in August 1945.
He returned to Harvard in 1945, and studied under Wassily Leontief. As his research assistant he produced the first set of capital-coefficients for the input-output model. Then he became interested in statistics and probability models. From 1949–50, he spent a fellowship year at Columbia University to study statistics more intensively. During that year he was also working on his Ph.D. thesis, an exploratory attempt to model changes in the size distribution of wage income using interacting Markov processes for employment-unemployment and wage rates.
