Sir Henry Roy Forbes Harrod (13 February 1900 – 8 March 1978) was an English economist. He is best known for writing The Life of John Maynard Keynes (1951) and for 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 School 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 remained in contact with Keynes until Keynes's death in 1946, and was later his biographer (1951). Harrod was additionally a Fellow at Nuffield College 1938 to 1947 and from 1954 to 1958.
At Oxford Harrod was part of the Railway Club, which included: Henry Yorke, Roy Harrod, Henry Thynne, 6th Marquess of Bath, David Plunket Greene, Edward Henry Charles James Fox-Strangways, 7th Earl of Ilchester, Brian Howard, Michael Parsons, 6th Earl of Rosse, John Sutro, Hugh Lygon, Harold Acton, Bryan Guinness, 2nd Baron Moyne, Patrick Balfour, 3rd Baron Kinross, Mark Ogilvie-Grant, John Drury-Lowe. 
During the Second World War, he was briefly in Winston Churchill's "S-branch" – a statistical section within the Admiralty.
At the 1945 General Election he stood as Liberal candidate for Huddersfield and finished third.
In 1966, Harrod, was the 2nd winner of the prestigious Bernhard-Harms-Preis.  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. 
Assar Lindbeck, the former chairman of the Nobel Prize Committee, wrote that Harrod would have been awarded a Nobel Memorial Prize in Economic Sciences if he had lived longer.
Harrod married Wilhelmine "Billa" Cresswell (1911–2005), step-daughter of General Sir Peter Strickland, in 1938.  One of their sons was Dominick Harrod, an economics correspondent for the BBC. 
After the death of his Cambridge friend and colleague, the economist John Maynard Keynes, in 1946, Harrod and Austin Robinson wrote a lengthy obituary of Keynes for The Economic Journal.  At the encouragement of Geoffrey Keynes, Harrod then undertook the task of writing a major biography of Keynes. The Life of John Maynard Keynes was published to widespread acclaim in 1951, at a time when most of Keynes's family and friends were still alive.
With the post-war influence of so-called Keynesian economics and then challenges to it, cultural interest in the Bloomsbury Group, and the publication of thirty volumes of The Collected Writings of John Maynard Keynes in the 1970s and 1980s,  high interest in Keynes's life led to further biographies, most prominently by Robert Skidelsky and Donald Moggridge, and to detailed studies such as by Donald Markwell on Keynes and international relations. These works have corrected and added details to the Keynes depicted by Harrod, and Skidelsky in particular has contrasted his account of Keynes with what he has depicted as Harrod's hagiography. 
The Harrod Papers are housed at the British Library. The papers can be accessed through the British Library catalogue. 
John Maynard Keynes, 1st Baron Keynes was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics.
Post-Keynesian economics is a school of economic thought with its origins in The General Theory of John Maynard Keynes, with subsequent development influenced to a large degree by Michał Kalecki, Joan Robinson, Nicholas Kaldor, Sidney Weintraub, Paul Davidson, Piero Sraffa and Jan Kregel. Historian Robert Skidelsky argues that the post-Keynesian school has remained closest to the spirit of Keynes' original work. It is a heterodox approach to economics.
Nicholas Kaldor, Baron Kaldor, born Káldor Miklós, was a Cambridge economist in the post-war period. He developed the "compensation" criteria called Kaldor–Hicks efficiency for welfare comparisons (1939), derived the cobweb model, and argued for certain regularities observable in economic growth, which are called Kaldor's growth laws. Kaldor worked alongside Gunnar Myrdal to develop the key concept Circular Cumulative Causation, a multicausal approach where the core variables and their linkages are delineated. Both Myrdal and Kaldor examine circular relationships, where the interdependencies between factors are relatively strong, and where variables interlink in the determination of major processes. Gunnar Myrdal got the concept from Knut Wicksell and developed it alongside Nicholas Kaldor when they worked together at the United Nations Economic Commission for Europe. Myrdal concentrated on the social provisioning aspect of development, while Kaldor concentrated on demand-supply relationships to the manufacturing sector. Kaldor also coined the term "convenience yield" related to commodity markets and the so-called theory of storage, which was initially developed by Holbrook Working.
Sir John Richards Hicks was a British economist. He is considered one of the most important and influential economists of the twentieth century. The most familiar of his many contributions in the field of economics were his statement of consumer demand theory in microeconomics, and the IS–LM model (1937), which summarised a Keynesian view of macroeconomics. His book Value and Capital (1939) significantly extended general-equilibrium and value theory. The compensated demand function is named the Hicksian demand function in memory of him.
Arthur Cecil Pigou was an English economist. As a teacher and builder of the School of Economics at the University of Cambridge, he trained and influenced many Cambridge economists who went on to take chairs of economics around the world. His work covered various fields of economics, particularly welfare economics, but also included Business cycle theory, unemployment, public finance, index numbers, and measurement of national output. His reputation was affected adversely by influential economic writers who used his work as the basis on which to define their own opposing views. He reluctantly served on several public committees, including the Cunliffe Committee and the 1919 Royal Commission on Income tax.
Lionel Charles Robbins, Baron Robbins, was a British economist, and prominent member of the economics department at the London School of Economics (LSE). He is known for his leadership at LSE, his proposed definition of economics, and for his instrumental efforts in shifting Anglo-Saxon economics from its Marshallian direction. He is famous for the quote, "Humans want what they can't have."
Colin Grant Clark was a British and Australian economist and statistician who worked in both the United Kingdom and Australia. He pioneered the use of gross national product (GNP) as the basis for studying national economies.
The Harrod–Domar model is a Keynesian model of economic growth. It is used in development economics to explain an economy's growth rate in terms of the level of saving and of capital. It suggests that there is no natural reason for an economy to have balanced growth. The model was developed independently by Roy F. Harrod in 1939, and Evsey Domar in 1946, although a similar model had been proposed by Gustav Cassel in 1924. The Harrod–Domar model was the precursor to the exogenous growth model.
Robert Jacob Alexander, Baron Skidelsky, is a British economic historian. He is the author of a three-volume award-winning biography of British economist John Maynard Keynes (1883–1946). Skidelsky read history at Jesus College, Oxford, and is Emeritus Professor of Political Economy at the University of Warwick, England.
Alvin Harvey Hansen was an American economist who taught at the University of Minnesota and was later a chair professor of economics at Harvard University. Often referred to as "the American Keynes", he was a widely read popular author on economic issues, and an influential advisor to the government on economic policy. Hansen helped create the Council of Economic Advisors and the Social Security system. He is best remembered today for introducing Keynesian economics in the United States in the 1930s and 40s.
Evsey David Domar was a Russian American economist, famous as developer of the Harrod–Domar model.
Richard Ferdinand Kahn, Baron Kahn, CBE, FBA was a British economist.
Sir Edward Austin Gossage Robinson, was a University of Cambridge economist. He was an undergraduate at Christ's College, Cambridge, and a fellow of Sidney Sussex College, Cambridge.
Donald John Markwell is an Australian social scientist, who has been described as a "renowned Australian educational reformer". He was appointed Head of St Mark's College, Adelaide, from November 2019. He was Senior Adviser to the Leader of the Government in the Australian Senate from October 2015 to December 2017, and was previously Senior Adviser on Higher Education to the Australian Minister for Education.
The Keynesian Revolution was a fundamental reworking of economic theory concerning the factors determining employment levels in the overall economy. The revolution was set against the then orthodox economic framework, namely neoclassical economics.
Athanasios "Tom" Asimakopulos was a Canadian economist, who was the "William Dow Professor of Political Economy" in the Department of Economics, McGill University, Montreal, Quebec, Canada. His monograph, Keynes's General Theory and Accumulation, reviews important areas of Keynes's General Theory and the theories of accumulation of two of his most distinguished followers, Roy Harrod and Joan Robinson.
Keynes: The Return of the Master is a 2009 book by economic historian Robert Skidelsky. The work discusses the economic theories and philosophy of John Maynard Keynes, and argues about their relevance to the world following the Financial crisis of 2007–2010. In contrast to the 30 years he needed to write his prize-winning biography on Keynes, the author was able to write this 240-page book in only three months.
Peace economics is a branch of conflict economics and focuses on the design of the sociosphere's political, economic, and cultural institutions and their interacting policies and actions with the goal of preventing, mitigating, or resolving violent conflict within and between societies. This violent conflict could be of any type and could involve either latent or actual violence. Recognizing the cost of violence, peace economics focuses on the benefits of (re)constructing societies with a view toward achieving irreversible, stable peace. Along with approaches drawn from other areas of scholarship, peace economics forms part of peace science, an evolving part of peace and conflict studies.
