Wassily Wassilyevich Leontief (Russian : Василий Васильевич Леонтьев; August 5, 1905 – February 5, 1999), was a Russian-American economist known for his research on input-output analysis and how changes in one economic sector may affect other sectors.
Russian is an East Slavic language, which is official in the Russian Federation, Belarus, Kazakhstan and Kyrgyzstan, as well as being widely used throughout Eastern Europe, the Baltic states, the Caucasus and Central Asia. It was the de facto language of the Soviet Union until its dissolution on 25 December 1991. Although nearly three decades have passed since the breakup of the Soviet Union, Russian is used in official capacity or in public life in all the post-Soviet nation-states, as well as in Israel and Mongolia.
An economist is a practitioner in the social science discipline of economics.
In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
Leontief won the Nobel Committee's Nobel Memorial Prize in Economic Sciences in 1973, and four of his doctoral students have also been awarded the prize (Paul Samuelson 1970, Robert Solow 1987, Vernon L. Smith 2002, Thomas Schelling 2005).
The Nobel Memorial Prize in Economic Sciences, commonly referred to as the Nobel Prize in Economics, is an award for outstanding contributions to the field of economics, and generally regarded as the most prestigious award for that field. The award's official name is The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel.
Paul Anthony Samuelson was an American economist. The first American to win the Nobel Memorial Prize in Economic Sciences, the Swedish Royal Academies stated, when awarding the prize in 1970, that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Economic historian Randall E. Parker has called him the "Father of Modern Economics", and The New York Times considered him to be the "foremost academic economist of the 20th century".
Robert Merton Solow, GCIH, 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 is currently Emeritus Institute Professor of Economics at the Massachusetts Institute of Technology, where he has been a professor since 1949. He was awarded the John Bates Clark Medal in 1961, the Nobel Memorial Prize in Economic Sciences in 1987, and the Presidential Medal of Freedom in 2014. Four of his PhD students, George Akerlof, Joseph Stiglitz, Peter Diamond and William Nordhaus later received Nobel Memorial Prizes in Economic Sciences in their own right.
Wassily Leontief was born on August 5, 1906, in Munich, Germany, the son of Wassily W. Leontief (professor of Economics) and Zlata (German spelling Slata; later Evgenia) Leontief (née Becker).W. Leontief, Sr., belonged to a family of old-believer merchants living in St. Petersburg since 1741. Genya Becker belonged to a wealthy Jewish family from Odessa. At 15 in 1921, Wassily, Jr., entered University of Leningrad in present-day St. Petersburg. He earned his Learned Economist degree (equivalent to Master of Arts) in 1925 at the age of 19.
Munich is the capital and most populous city of Bavaria, the second most populous German federal state. With a population of around 1.5 million, it is the third-largest city in Germany, after Berlin and Hamburg, and thus the largest which does not constitute its own state, as well as the 12th-largest city in the European Union. The city's metropolitan region is home to 6 million people. Straddling the banks of the River Isar north of the Bavarian Alps, it is the seat of the Bavarian administrative region of Upper Bavaria, while being the most densely populated municipality in Germany. Munich is the second-largest city in the Bavarian dialect area, after the Austrian capital of Vienna.
Economics is the social science that studies the production, distribution, and consumption of goods and services.
In Eastern Orthodox church history, especially within the Russian Orthodox Church, the Old Believers or Old Ritualists are Eastern Orthodox Christians who maintain the liturgical and ritual practices of the Eastern Orthodox Church as they were before the reforms of Patriarch Nikon of Moscow between 1652 and 1666. Resisting the accommodation of Russian piety to the contemporary forms of Greek Orthodox worship, these Christians were anathematized, together with their ritual, in a Synod of 1666–67, producing a division in Eastern Europe between the Old Believers and those who followed the state church in its condemnation of the Old Rite.
Leontief sided with campaigners for academic autonomy, freedom of speech and in support of Pitirim Sorokin. As a consequence, he was detained several times by the Cheka. In 1925, he was allowed to leave the USSR, mostly because the Cheka believed that he was mortally ill with a sarcoma, a diagnosis that later proved false.He continued his studies at the Frederick William University in Berlin and, in 1928 earned a Ph.D. degree in economics under the direction of Werner Sombart, writing his dissertation on The Economy as Circular Flow (original German title: Die Wirtschaft als Kreislauf).
Pitirim Alexandrovich Sorokin was a Russian-born American sociologist and political activist, best known for his contributions to the social cycle theory.
The KGB, translated in English as Committee for State Security, was the main security agency for the Soviet Union from 1954 until its break-up in 1991. As a direct successor of preceding agencies such as the Cheka, NKGB, NKVD and MGB, the committee was attached to the Council of Ministers. It was the chief government agency of "union-republican jurisdiction", acting as internal security, intelligence and secret police. Similar agencies were constituted in each of the republics of the Soviet Union aside from Russian SFSR, and consisted of many ministries, state committees and state commissions.
A sarcoma is a cancer that arises from transformed cells of mesenchymal origin. Connective tissue is a broad term that includes bone, cartilage, fat, vascular, or hematopoietic tissues, and sarcomas can arise in any of these types of tissues. As a result, there are many subtypes of sarcoma, which are classified based on the specific tissue and type of cell from which the tumor originates. It is important to note that sarcomas are primary connective tissue tumors, meaning that they arise in connective tissues. This is in contrast to secondary connective tissue tumors, which occur when a cancer from elsewhere in the body spreads to the connective tissue. The word sarcoma is derived from the Greek σάρξ sarx meaning "flesh".
From 1927 to 1930, he worked at the Institute for the World Economy of the University of Kiel. There he researched the derivation of statistical demand and supply curves. In 1929, he traveled to China to assist its ministry of railroads as an advisor.
The Kiel Institute for the World Economy is an independent, non-profit economic research institute and think tank based in Kiel, Germany. In 2017, it was ranked as one of the top 50 most influential think tanks in the world and was also ranked in the top 15 in the world for economic policy specifically. German business newspaper, Handelsblatt, referred to the Institute as "Germany's most influential economic think tank", while Die Welt, stated that "The best economists in the world are in Kiel".
The University of Kiel, officially the Christian-Albrecht University of Kiel, is a university in the city of Kiel, Germany. It was founded in 1665 as the Academia Holsatorum Chiloniensis by Christian Albert, Duke of Holstein-Gottorp and has approximately 27,000 students today. Kiel University is the largest, oldest, and most prestigious in the state of Schleswig-Holstein. Until 1864/66 it was not only the northernmost university in Germany but at the same time the 2nd largest university of Denmark. Faculty, alumni, and researchers of the Kiel University have won 12 Nobel Prizes. Kiel University has been a member of the German Universities Excellence Initiative since 2006. The Cluster of Excellence The Future Ocean, which was established in cooperation with the GEOMAR Helmholtz Centre for Ocean Research Kiel in 2006, is internationally recognized. The second Cluster of Excellence "Inflammation at Interfaces" deals with chronic inflammatory diseases. The Kiel Institute for the World Economy is also affiliated with Kiel University.
In 1931, he went to the United States and was employed by the National Bureau of Economic Research.
The National Bureau of Economic Research (NBER) is an American private nonprofit research organization "committed to undertaking and disseminating unbiased economic research among public policymakers, business professionals, and the academic community." The NBER is well known for providing start and end dates for recessions in the United States.
During World War II, Leontief served as consultant at the U. S. Office of Strategic Services.
Leontief joined Harvard University's department of economics in 1932 and in 1946 became professor of economics there.
In 1949, Leontief used an early computer at Harvard and data from the U.S. Bureau of Labor Statistics to divide the U.S. economy into 500 sectors. Leontief modeled each sector with a linear equation based on the data and used the computer, the Harvard Mark II, to solve the system, one of the first significant uses of computers for mathematical modeling,along with George W. Snedecor's usage of the Atanasoff–Berry computer.
Leontief set up the Harvard Economic Research Project in 1948 and remained its director until 1973. Starting in 1965, he chaired the Harvard Society of Fellows.
In 1975, Leontief joined New York University and founded and directed the Institute for Economic Analysis. He taught graduate and undergraduate classes.
In 1932, Leontief married the poet Estelle Marks. Their only child, Svetlana Leontief Alpers, was born in 1936. Estelle wrote a memoir, Genia and Wassily,of their relations with his parents after they came to the US as émigrés.
As hobbies Leontief enjoyed fly fishing, ballet, and fine wines. He vacationed for years at his farm in West Burke, Vermont, but after moving to New York in the 1970s moved his summer residence to Lakeville, Connecticut.
Leontief died in New York City on Friday, February 5, 1999 at the age of 93. His wife died in 2005.
Leontief is credited with developing early contributions to input-output analysis and earned the Nobel Prize in Economics for his development of its associated theory. He has also made contributions in other areas of economics, such as international trade where he documented the Leontief paradox. He was also one of the first to establish the composite commodity theorem.
Leontief earned the Nobel Prize in economics for his work on input-output tables. Input-output tables analyze the process by which inputs from one industry produce outputs for consumption or for inputs for another industry. With the input-output table, one can estimate the change in demand for inputs resulting from a change in production of the final good. The analysis assumes that input proportions are fixed; thus the use of input-output analysis is limited to rough approximations rather than prediction. Input-output was novel and inspired large-scale empirical work; in 2010 its iterative method was recognized as an early intellectual precursor to Google's PageRank.
Leontief used input-output analysis to study the characteristics of trade flow between the U.S. and other countries, and found what has been named Leontief's paradox; "this country resorts to foreign trade in order to economize its capital and dispose of its surplus labor, rather than vice versa", i.e., U.S. exports were relatively labor-intensive when compared to U.S. imports. This is the opposite of what one would expect, considering the fact that the U.S.'s comparative advantage was in capital-intensive goods. According to some economists, this paradox has since been explained as due to the fact that when a country produces "more than two goods, the abundance of capital relative to labor does not imply that the capital intensity of its exports should exceed that of imports."
Leontief was also a very strong proponent of the use of quantitative data in the study of economics. Throughout his life Leontief campaigned against "theoretical assumptions and non-observed facts".According to Leontief, too many economists were reluctant to "get their hands dirty" by working with raw empirical facts. To that end, Wassily Leontief did much to make quantitative data more accessible, and more indispensable, to the study of economics.
The Global Development and Environment Institute at Tufts University awards the Leontief Prize in Economics each year in his honor.
Leontief is listed in the Russian-American Chamber of Fame of Congress of Russian Americans, which is dedicated to Russian immigrants who made outstanding contributions to American science or culture.
Much of current academic teaching and research has been criticized for its lack of relevance, that is, of immediate practical impact. ... The trouble is caused, however, not by an inadequate selection of targets, but rather by our inability to hit squarely on them, ... by the palpable inadequacy of the scientific means with which they try to solve them. ... The weak and all too slowly growing empirical foundations clearly cannot support the proliferating superstructure of pure, or should I say, speculative economic theory.... By the time it comes to interpretations of the substantive conclusions, the assumptions on which the model has been based are easily forgotten. But it is precisely the empirical validity of these assumptions on which the usefulness of the entire exercise depends. ... A natural Darwinian feedback operating through selection of academic personnel contributes greatly to the perpetuation of this state of affairs.
The role of humans as the most important factor of production is bound to diminish in the same way that the role of horses in agricultural production was first diminished and then eliminated by the introduction of tractors.

Leontief's paradox in economics is that a country with a higher capital per worker has a lower capital/labor ratio in exports than in imports.
In economics, gross output (GO) is the measure of total economic activity in the production of new goods and services in an accounting period. It is a much broader measure of the economy than gross domestic product (GDP), which is limited mainly to final output. As of first-quarter 2019, the Bureau of Economic Analysis estimated gross output in the United States to be $37.2 trillion, compared to $21.1 trillion for GDP.

Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. By convention, these applied methods are beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, and other computational methods. Proponents of this approach claim that it allows the formulation of theoretical relationships with rigor, generality, and simplicity.
