1. Life

Sir Richard Stone's life journey was marked by a significant transition from law to economics, driven by a desire to address societal challenges, and a distinguished career that saw him establish and lead key economic research institutions.

1.1. Early Life and Education

Richard Stone was born in London, England, on 30 August 1913. He received an English upper-middle-class education, attending Cliveden Place and Westminster School. Notably, he was not taught mathematics and science until secondary school. At the age of 17, he accompanied his father to India, where his father had been appointed a judge in Madras. During his year in Asia, Stone also visited Malaya, Singapore, and Indonesia.

In 1931, he returned to London and matriculated at Gonville and Caius College, Cambridge, where he initially studied law for two years. However, Stone soon changed his focus to economics. This shift was motivated by his belief that "if there were more economists, the world would be a better place," a conviction strengthened by the high unemployment rates during the Great Slump of the 1930s. Despite his parents' initial disappointment with his career choice, Stone pursued economics with great enthusiasm. At Cambridge, he received supervision from notable economists such as Richard Kahn and Gerald Shove. His quantitative mindset was particularly influenced by Colin Clark, his statistics teacher, who introduced Stone to his project on measuring national income. This project laid the groundwork for Stone's future Nobel Prize-winning work, and he and Clark became close friends.

1.2. Early Career and World War II Activities

After graduating from Cambridge in 1935, Stone worked at Lloyd's of London until World War II. During the war, he served as a statistician and economist for the British Government, collaborating with James Meade. They were tasked with analyzing the UK's economy in relation to the nation's total resources available for the war effort. This crucial work led to the development of the early versions of the system of national accounts and resulted in the publication of the UK's first national accounts in 1941.

Their collaboration ended after 1941 when their office was divided. Meade took responsibility for the Economic Section, while Stone focused on national income. In his new role at the Central Statistical Office, Stone served as an assistant to John Maynard Keynes. He concluded his government service when the war ended in 1945.

1.3. Academic Career

Following World War II, Stone embarked on a distinguished academic career at Cambridge University, where he played a pivotal role in shaping economic research and methodology.

1.3.1. Department of Applied Economics at Cambridge

In 1945, Stone took up an academic position at Cambridge as the founder and first director of the newly established Department of Applied Economics (DAE), a role he held until 1955. Under his leadership, the DAE focused on research programs in economic theory and statistical methodology, attracting many leading economists of the era. Notable contributions from the department during this period included Durbin and Watson's work on testing serial correlation in econometrics, and Alan Prest and Derek Rowe's research on demand analysis. Stone's strategic direction transformed the DAE into one of the world's foremost centers for quantitative economic research. His own projects at the DAE included national accounting, where he employed Agatha Chapman as a research associate, as well as analyses of consumer demand and the development of a system of socio-demographic accounts.

1.3.2. Cambridge Growth Project

In 1955, Stone stepped down from his directorship at the DAE upon his appointment as the P.D. Leake Chair of Finance and Accounting at Cambridge, a position he held until becoming emeritus in 1980. In this capacity, he initiated the Cambridge Growth Project alongside J.A.C. Brown. This project was instrumental in developing the Cambridge Multisectoral Dynamic Model (MDM) for the British economy. The project utilized Social Accounting Matrices (SAM), which also formed the basis for computable equilibrium models later developed at the World Bank. Stone was eventually succeeded as the leader of the Cambridge Growth Project by Terry Barker. In 1978, Cambridge Econometrics, a company founded by members of the DAE, was established with Stone as its first honorary president. The company continues to develop the MDM and uses it for economic forecasting.

1.3.3. Other Academic and Societal Engagements

Beyond his work at the DAE and the Cambridge Growth Project, Stone held several other influential academic and societal roles. From 1970 to 1972, he served as the Chairman of the Faculty Board of Economics and Politics at Cambridge. He was also President of the Royal Economic Society from 1978 to 1980. Furthermore, Stone served as the President of the Econometric Society in 1955, demonstrating his significant standing within the field of quantitative economics. His influence extended to international bodies, as he was a central member of the United Nations Statistical Commission, playing a key role in the development of the 1968 System of National Accounts (SNA).

2. Major Achievements and Contributions

Sir Richard Stone's most significant contributions to economics lie in his pioneering work on national accounting and his methodological advancements in economic analysis, which fundamentally reshaped the field.

2.1. Development of the System of National Accounts (SNA)

Stone is widely regarded as the 'father of national income accounting' for his pivotal role in developing a comprehensive accounting model to track economic activities. His pioneering approach involved the application of double-entry bookkeeping to national accounting. This method, which dictates that every income item on one side of a balance sheet must be balanced by an expenditure item on the opposite side, provided a reliable and systematic way to track trade and wealth transfers on a global scale. This double-entry system forms the foundation of nearly all modern accounting practices today.

His work culminated in the development of the System of National Accounts (SNA), a standardized framework for measuring economic activity. Stone was a central figure in the United Nations Statistical Commission, where he played a crucial role in the development of the 1968 version of the SNA, often referred to as the "New SNA." This system integrates various economic indicators, including input-output tables, national income accounts, flow of funds accounts, balance of payments, and national balance sheet, to systematically record the national economy from the perspectives of goods, money, flows, and stocks. Stone himself acknowledged the historical lineage of his work, mentioning François Quesnay and his Tableau économique during his Nobel acceptance speech, recognizing it as one of the earliest works to examine interconnected economic sectors on a global level.

2.2. Economic Analysis Methodology

Stone's methodological contributions extended beyond national accounting to various areas of economic analysis. His studies on consumer demand statistics and demand modeling are among his most cited works, providing crucial tools for understanding consumer behavior. He also made significant contributions to the fields of economic growth and input-output analysis. Furthermore, Stone is credited with devising the "Stone method," a fundamental rule for handling byproducts in input-output tables, which is highly regarded for its practical application in economic modeling. These contributions provided economists with robust tools for understanding complex economic dynamics and informing policy decisions.

2.3. Nobel Memorial Prize in Economic Sciences

In 1984, Sir Richard Stone was awarded the Nobel Memorial Prize in Economic Sciences for his pioneering work in developing systems of national accounting. The Nobel Committee recognized the profound impact of his contributions on economic measurement and policy, highlighting how his systematic framework revolutionized the way countries collect, organize, and analyze economic data. His work provided the essential statistical infrastructure for informed economic governance and facilitated evidence-based approaches to addressing societal challenges.

3. Personal Life

Sir Richard Stone was married three times. His first marriage was in 1936 to Winifred Mary Jenkins, also from Cambridge. Both shared a passion for economics and co-founded a monthly paper called Trends, which served as a supplement to the periodical Industry Illustrated. Trends featured articles on British economic conditions. This marriage ended in 1940.

In 1941, Stone married his second wife, Feodora Leontinoff, who passed away in 1956.

His third marriage, in 1960, was to Giovanna Saffi (1919-2009), the great-grandchild of the Italian patriot Aurelio Saffi. Giovanna became his partner in many of his professional endeavors, including their collaboration on rewriting his renowned book "National Income and Expenditure" in 1961. He was survived by Giovanna and his daughter, Caroline.
