John Richard Hicks

Sir John Richard Hicks (April 8, 1904 – May 20, 1989) was a British economist, one of the most influential economists of the twentieth century. He contributed to the field of economics with his IS/LM model, which summarized the Keynesian view of macroeconomics, and his statement of consumer demand theory in microeconomics. In 1972, Hicks was awarded the Nobel Prize in Economics for his contributions to general economic equilibrium theory and welfare theory.

Life

John Richard Hicks was born in Leamington Spa, Warwickshire, England, the son of a journalist. He was educated at Clifton College (1917-1922) and later received a mathematical scholarship to study at Balliol College, at the University of Oxford, where he enrolled in 1923.

Although initially specializing in mathematics, Hicks was not content and had a strong interest for literature and history. He transferred in 1923 to the newly opened School of Philosophy, Politics and Economics. However, he did not have adequate qualification in any of the subjects that he studied, and graduated with a second-class degree.

In the 1920s, economists were very scarce and so Hicks picked up a temporary lectureship at the London School of Economics, which was then continued. He started as a labor economist, doing descriptive work on industrial relations, but gradually moved over to the analytical side. He discovered that his mathematics, by that time almost forgotten, could be revived, and was sufficient to cope with what anyone used in economics.

In 1935, Hicks married fellow economist, Ursula Webb. At that time he transferred to Cambridge University where he became a lecturer in economics. During his three years in Cambridge, Hicks completed his Value and Capital, which was based on the work he had done in London. He was also a fellow of Gonville and Caius College, at Cambridge, from 1935 to 1938.

In 1938, Hicks became professor at the University of Manchester. It was there that he started to focus mainly on [[welfare economics], and its application to social accounting. In 1946 he returned to Oxford, first as a research fellow of Nuffield College (1946-1952), then as Drummond Professor of Political Economy (1952-1965), and finally as a research fellow of All Souls College (1965-1971).

Hicks became a fellow of the British Academy in 1942; a foreign member of the Royal Swedish Academy in 1948, of the Accademia dei Lincei, Italy, in 1952, and of the American Academy in 1958. He was knighted in 1964. He received honorary doctor degrees from several British Universities - Glasgow, Manchester, Leicester, East Anglia, and Warwick - as well as of the Technical University of Lisbon, Portugal.

In 1972, Hicks received the Nobel Prize in Economics, together with Kenneth J. Arrow, for his work on general economic equilibrium theory and welfare theory.

John Hicks died on May 20, 1989 in Blockley, Gloucestershire, Great Britain.

Work

Microeconomics

Hicks' early work was as a labor economist culminated in The Theory of Wages (1932), still considered a standard in the field. In that book he gave his own interpretation of marginal productivity theory, attempting to reinvoke interest in it. In the book he also introduced his famous "elasticity of substitution" which is defined as “the elasticity of the ratio of two inputs to a production (or utility) function with respect to the ratio of their marginal products (or utilities).”

In the mid-1930s, Hicks worked on a way to unite various theories of imperfect competition, introducing the concept of "conjectural variations." He also attempted to resurrect the Lausanne School of economics developed by Léon Walras and Vilfredo Pareto. The central feature of the Lausanne School was its development of general equilibrium theory which he attempted to introduce to the English-speaking world. In 1934 he tried to do the same with his review of Gunnar Myrdal's work, which drew attention to the Stockholm School of economics.

His magnum opus was Value and Capital, published in 1939. This book built upon ordinal utility and mainstreamed the now-standard distinction between the substitution effect and the income effect for an individual in demand theory for the case of two consumer goods. It generalized analysis to the case of one consumer good and a composite good, that is, all other goods. It also aggregated individuals and businesses through demand and supply across the economy, anticipating the aggregation problem, most acutely for the stock of capital goods.

Hicks' book introduced general equilibrium theory to an English-speaking audience, refined the theory for dynamic analysis, and for the first time attempted a rigorous statement of stability conditions for general equilibrium. In the course of analysis Hicks formalized comparative statics. In the same year, he also developed the famous "compensation" criteria called Kaldor-Hicks efficiency for welfare comparisons of alternative public policies or economic states.

The book Value and Capital had tremendous impact. Much of modern microeconomics, as well as general equilibrium theory, has its roots in this book.

Macroeconomics

Hicks' most familiar contribution in macroeconomics was the Hicks-Hansen IS-LM model, which formalized the theory of John Maynard Keynes. The model describes the economy as a balance between three commodities: money, consumption, and investment. This model eventually became the starting point of the Neo-Keynesian synthesis in economic systems which dominated in the mid-twentieth century. It later came under criticism in the early 1970s, when high inflation and growing unemployment seemed to be incompatible with the predictions of the system. In one of his later works, published in 1980, Hicks criticized his own model, asserting it had omitted some crucial components of Keynes' arguments, especially those related to uncertainty.

Among his other contributions to macroeconomics is the concept of "liquidity trap" – which happens in a stagnant economy, when the nominal interest rate is close or equal to zero, and when people start to keep their savings only in short-term bank accounts, expecting a recession. He also developed the concept of "temporary equilibrium," enlarged the "Linear Theory" and elaborated on the von Neumann turnpike.

In the 1970s Hicks worked to resurrect the Austrian school of economics, attempting to formalize the Austrian theory of capital which included both fixed and circulating capital.

Legacy

John Richard Hicks was one of the most important and influential economists of the twentieth century. He broke with Marshallian tradition that dominated the English-speaking world in the 1930s, in what is commonly known as “Paretian revival,” and reintroduced the theories of Leon Walras, the Austrian school, and the Swedish school based on the work of Gunnar Myrdal and Bertil Ohlin. His work, together with other great economic thinkers such as Paul Samuelson, Oskar Lange, Abba Lerner, Maurice Allais, and Harold Hotellin, helped consolidate the Marginalist revolution, which started some fifty years before.

Although his work was deep enough, and his influence strong enough to form a school of thought, Hicks never gathered any great number of followers. The reason for this is probably that his approach was critical and eclectic, building upon every school that had something to offer. He however inspired generations of thinkers, especially in the neo-Walrasian tradition, including Michio Morishima, Frank H. Hahn, and Takashi Negishi.
