Jacob Marschak (23 July 1898 – 27 July 1977) was an American economist.
Born in a Jewish family of Kyiv,   Jacob Marschak (until 1933 Jakob) was the son of a jeweler. During his studies he joined the social democratic Menshevik Party, becoming a member of the Menshevik International Caucus. In 1918 he was the labor minister in the Terek Soviet Republic. In 1919 he emigrated to Germany, where he studied at the University of Berlin and the University of Heidelberg. 
From 1922 to 1926 he was a journalist, and in 1928 he joined the new Kiel Institut für Weltwirtschaft . With the gathering Nazi storm, he emigrated to England, where he went to Oxford to teach at the Oxford Institute of Statistics,  which was funded by the Rockefeller Foundation, allowing him to emigrate in 1939 to the United States.  After teaching at the New School for Social Research, in 1943 he went to University of Chicago, where he led the Cowles Commission.  He followed the commission's move to Yale University,  and he then became a professor at UCLA in 1960.  
In 1972 he co-founded Team Theory with Roy Radner.
Marschak was fluent in approximately one dozen languages. Shortly before he was due to become president of the American Economic Association, he died from a cardiac arrest. 
UCLA sponsors the recurring Jacob Marschak Interdisciplinary Colloquium on Mathematics in the Behavior Sciences.
Kenneth Joseph Arrow was an American economist, mathematician, writer, and political theorist. He was the joint winner of the Nobel Memorial Prize in Economic Sciences with John Hicks in 1972.
Gérard Debreu was a French-born economist and mathematician. Best known as a professor of economics at the University of California, Berkeley, where he began work in 1962, he won the 1983 Nobel Memorial Prize in Economic Sciences.
Theory of Games and Economic Behavior, published in 1944 by Princeton University Press, is a book by mathematician John von Neumann and economist Oskar Morgenstern which is considered the groundbreaking text that created the interdisciplinary research field of game theory. In the introduction of its 60th anniversary commemorative edition from the Princeton University Press, the book is described as "the classic work upon which modern-day game theory is based."
Harold Hotelling was an American mathematical statistician and an influential economic theorist, known for Hotelling's law, Hotelling's lemma, and Hotelling's rule in economics, as well as Hotelling's T-squared distribution in statistics. He also developed and named the principal component analysis method widely used in finance, statistics and computer science.
John Brian Taylor is the Mary and Robert Raymond Professor of Economics at Stanford University, and the George P. Shultz Senior Fellow in Economics at Stanford University's Hoover Institution.
Michio Morishima was a Japanese heterodox economist and public intellectual who was the Sir John Hicks Professor of Economics at the London School of Economics from 1970–88. He was also professor at Osaka University and member of the British Academy. In 1976 he won the Order of Culture.
Hirofumi Uzawa was a Japanese economist.
Sanford "Sandy" Jay Grossman is an American economist and hedge fund manager specializing in quantitative finance. Grossman’s research has spanned the analysis of information in securities markets, corporate structure, property rights, and optimal dynamic risk management. He has published widely in leading economic and business journals, including American Economic Review, Journal of Econometrics, Econometrica, and Journal of Finance. His research in macroeconomics, finance, and risk management has earned numerous awards. Grossman is currently Chairman and CEO of QFS Asset Management, an affiliate of which he founded in 1988. QFS Asset Management shut down its sole remaining hedge fund in January 2014.
Takeshi Amemiya is an economist specializing in econometrics and the economy of ancient Greece.
Lionel Wilfred McKenzie was an American economist. He was the Wilson Professor Emeritus of Economics at the University of Rochester. He was born in Montezuma, Georgia. He completed undergraduate studies at Duke University in 1939 and subsequently moved to Oxford that year as a Rhodes Scholar. McKenzie worked with the Cowles Commission while it was in Chicago and served as an assistant professor at Duke from 1948–1957. Having received his Ph.D. at Princeton University in 1956, McKenzie moved to Rochester where he was responsible for the establishment of the graduate program in economics.
Leonid Hurwicz was a Polish-American economist and mathematician, known for his work in game theory and mechanism design. He originated the concept of incentive compatibility, and showed how desired outcomes can be achieved by using incentive compatible mechanism design. Hurwicz shared the 2007 Nobel Memorial Prize in Economic Sciences for his seminal work on mechanism design. Hurwicz was one of the oldest Nobel Laureates, having received the prize at the age of 90.
Marc Leon Nerlove is an American agricultural economist and econometrician and a distinguished university professor emeritus in agricultural and resource economics at the University of Maryland. He was awarded the John Bates Clark Medal from the American Economic Association (AEA) in 1969 and held appointments at eight different universities from 1958–2016. The Clark Medal is awarded to an economist under the age of 40 who “is judged to have made the most significant contribution to economic thought and knowledge”, and when the AEA appointed him as a distinguished fellow in 2012, they cited his development of widely used econometric methods across a range of subjects, including supply and demand, time series analysis, production functions, panel analysis, and family demography.
Griffith Conrad Evans was a mathematician working for much of his career at the University of California, Berkeley. He is largely credited with elevating Berkeley's mathematics department to a top-tier research department, having recruited many notable mathematicians in the 1930s and 1940s.
Roy Radner was Leonard N. Stern School Professor of Business at New York University. He was a micro-economic theorist. Radner's research interests included strategic analysis of climate change, bounded rationality, game-theoretic models of corruption, pricing of information goods and statistical theory of data mining. Previously he was a faculty member at the University of California, Berkeley, and a Distinguished Member of Technical Staff at AT&T Bell Laboratories.
David Schmeidler was an Israeli mathematician and economic theorist. He was a Professor Emeritus at Tel Aviv University and the Ohio State University.
Ross Marc Starr is an American economist who specializes in microeconomic theory, monetary economics and mathematical economics. He is a professor at the University of California, San Diego.
In economics, non-convexity refers to violations of the convexity assumptions of elementary economics. Basic economics textbooks concentrate on consumers with convex preferences and convex budget sets and on producers with convex production sets; for convex models, the predicted economic behavior is well understood. When convexity assumptions are violated, then many of the good properties of competitive markets need not hold: Thus, non-convexity is associated with market failures, where supply and demand differ or where market equilibria can be inefficient. Non-convex economies are studied with nonsmooth analysis, which is a generalization of convex analysis.
Convexity is an important topic in economics. In the Arrow–Debreu model of general economic equilibrium, agents have convex budget sets and convex preferences: At equilibrium prices, the budget hyperplane supports the best attainable indifference curve. The profit function is the convex conjugate of the cost function. Convex analysis is the standard tool for analyzing textbook economics. Non‑convex phenomena in economics have been studied with nonsmooth analysis, which generalizes convex analysis.
Hukukane Nikaido was a Japanese economist.
Charles Frederick Roos was an American economist who made contributions to mathematical economics. He was one of the founders of the Econometric Society together with American economist Irving Fisher and Norwegian economist Ragnar Frisch in 1930. He served as Secretary-Treasurer during the first year of the Society and was elected as President in 1948. He was director of research of the Cowles Commission from September 1934 to January 1937.
