Hagemann focuses on John R. Hicks, the first British economist to receive the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel in 1972. Hicks felt a lifelong commitment to London School of Economics (LSE), the institution that made him an economist and where he taught from 1926 to 1935. Hagemann discusses how Hicks’s later works at Cambridge, Manchester and Oxford are linked to his earlier influences at LSE. The emphasis is not only on his work on general equilibrium theory and welfare economics but also on Hicks’s other major works from wage theory to monetary theory, capital and growth theory, and the challenges posed by Hayek and Keynes. Hicks’s deep interest in (economic) history and history of economic thought also influenced his work as a theoretician.
