Anite Arrow Summers (born 1925) is a Senior Research Fellow at the Sell-Lurie Real Estate Center and Professor Emerita of Public Policy and Management at the University of Pennsylvania. This collection primarily documents her professional life and family connections to other notable economists. It was acquired as part of the Economists' Papers Archive.

This collection documents Summers' career as an economist. It provides a sample of her professional activities, particularly her research on urban economics, education and economics, and the local economy in Philadelphia.

The collection also documents her familial ties to other prominent economists, such as her husband Robert Summers, her brother Kenneth J. Arrow, and her brother-in-law (via Robert) Paul A. Samuelson.

John Chipman (1926-1922) was Regents' Professor Emeritus of Economics at the University of Minnesota. This collection documents his professional life through his correspondence, writings, research, and professional activities. It was acquired as part of the Economists' Papers Archive.

This collection consists of Chipman's drafts, publications, lecture notes, correspondence, and other files documenting his scholarship, writings, and teachings at the University of Minnesota. Prominent themes include international trade, with extensive research on West Germany during the Cold War; linear programming; welfare economics; econometrics; the writings and impact of Vilfredo Pareto; and Chipman's collaboration and friendships with other economists.

The range of Chipman's research and writings are represented in the Writings series, where files are arranged alphabetically by title. Files typically include drafts and published versions, usually offprints, as well as occasional correspondence and notes by Chipman documenting the development of the paper or essay.

The Name Files series includes a range of material (including correspondence, writings, notes, and subject files), arranged alphabetically by name, that document his professional relationships and communications with publishers, professional organizations, or other scholars, as well as his ongoing collaboration with other economists, including Leonid Hurwicz, James C. Moore, Tjalling Koopmans, Paul Samuelson, Eugen Slutsky, and Ragnar Frisch.

Finally, the Engagements series includes Chipman's lecture notes, exams, and reading lists from his years as a professor in the Economics Department, as well as event files from conferences, workshops, travels, awards, and other activities over the course of his career as an economist.

Lionel McKenzie (1919-2010) was the Wilson Professor of Economics, Emeritus at the University of Rochester (after beginning his career at Duke University). This collection primarily documents his professional life through his correspondence, writings, research, teaching, and professional activities. It forms part of the Economists' Papers Archive.

Through correspondence, research notes, article drafts, teaching material, lectures, and published materials, this collection provides a broad overview of McKenzie's professional career. His greatest contribution to economics was his work in conjunction with Kenneth Arrow and Gerard Debreu on general equilibrium, and his writings on capital theory and turnpike theory, all of which are documented in a variety of forms throughout the collection. Significant correspondents include noted economists Paul Samuelson, Tjalling Koopmans, and Robert Solow. Other aspects of his career are documented, such as his involvement in a number of economic organizations, especially the Econometric Society and the Mathematical Social Sciences Board; his role as organizer of a number of academic conferences, such as the Value and Capital Conference of 1988; and his teaching career at Duke University from 1948-1957 and the University of Rochester from 1957-1989.

The Conferences series includes material from conferences McKenzie attended and organized throughout his career and includes copies of programs, articles given, and other related documents.

The Correspondence series, the largest of the collection, contains largely official and routine correspondence, but also includes a sizeable number of letters on intellectual topics.

The Research and Writings series, the second largest, has various drafts and iterations of most of McKenzie's published work as well as some unpublished material. Many of the notes contain complicated mathematical notations documenting the theoretical foundations for his work. A small set of writings by others, chiefly on game theory and convex sets, conclude the series.

The Teaching series houses syllabi and other materials from the seminars he taught, including many versions of the handwritten text for his general equilibrium seminar, documenting his teaching methods as well as the evolution in his thinking on the subject.

In the Organizations series, extensive documentation can be found of McKenzie's involvement with various economic organizations, including internal discussions on the workings of many of these groups.

The smallest group of records, the Personal series, contains curriculum vitae, personal correspondence, and other ephemera.

Louise Curley (1922-2015) was an economist who studied with Paul Samuelson and collaborated with Leonard Silk. This collection contains her PhD dissertation, a preliminary edition of Samuelson's Economics: An Introductory Analysis (1946), and a consulting report for McGraw-Hill that she coauthored with Silk. It was acquired as part of the Economists' Papers Archive.

This collection contains a typescript copy of Curley's PhD dissertation "The Excess Profits Tax of the United States in World War II" (MIT, 1946); a preliminary edition of Samuelson's Economics: An Introductory Analysis (1946); and "Forecasting Business Trends," a bound consulting report for McGraw-Hill that she co-authored with Leonard Silk in 1956.

Nicholas Georgescu-Roegen (1906-1994) was a professor emeritus of economics at Vanderbilt University. This collection primarily documents his professonal life through his correspondence, writings, research, and professional and faculty activities. It forms part of the Economists' Papers Archive.

The bulk of the collection consists of Georgescu-Roegen's writings and lectures, correspondence, research and subject files, audiovisual recordings, and engagement files. Most materials date from the 1960s-1980s and relate to his professional life as a professor at Vanderbilt University. Notable correspondents include Joseph Schumpter, Friedrich von Hayek, Paul Samuelson, and other preeminent economists. Georgescu-Roegen's work as editor for Econometrica and his extensive writings on entropy and utility are also represented in the collection. A small portion of materials date from his administrative work as a Romanian official. Typed transcripts and other documents reveal details concerning political conditions in Romania during the period of the provisional government and the Armistice trials following World War II. During this period, he served the new government in various capacities before he fled the country with his wife in 1948.

Paul Samuelson (1915-2009) was a Nobel Prize winner and an Institute Professor Emeritus (of economics) at the Massachusetts Institute of Technology. This collection documents his professional life through his correspondence, writings and speeches, and professional and faculty activies. It was acquired as part of the Economists' Papers Archive.

This collections covers nearly all aspects of Samuelson's long career. Materials are arranged in the original order maintained by Samuelson, and include his professional correspondence files; unpublished writings, notes, drafts and fragments; audiovisual materials; documents regarding awards, including the Nobel Prize; files relating to various grants, committees, and projects; teaching materials from his years at MIT; files of speeches; and publication files, including professional and mainstream media articles. Significant correspondents include Milton Friedman, Don Patinkin, and Robert Solow, as well as many other notable economists, Nobel prize winners, politicians, and scientists. Material can also be found on economic programs at institutions such as MIT, where Samuelson established a renowned economics faculty. Researchers will find materials representing Samuelson's work on diverse topics of economic theory, including the history of economic thought (post-Keynesian economics, neoclassical economics, and thinkers such as Marx, Sraffa, and Ricardo), financial economics, growth theory, international finance, inflation, stability, welfare economics, post-World War economic policies and stabilization, stochastic analysis, utility, monetary policy, Marxist economics, biological economics (including population and gender studies), thermodynamics, and mathematical economics. Samuelson's insights on many of these subjects serve as organizational themes for large sections in the Unpublished Writings series. Finally, the Samuelson papers also document his strong contributions to the US government, especially his work for the Federal Reserve, and to federally-funded projects, professional committees and boards, and organizations and societies, beginning in the 1940s and continuing throughout his career.

The Correspondence series spans Samuelson's entire career, beginning in the 1930s. It consists mainly of professional exchanges with his colleagues in the US and other countries. There are also files of correspondence with a wide variety of political and academic figures, presses, and media organizations. There is frequent correspondence with President Kennedy, for whom he was an economic advisor. Besides the named folders that represent notable economists such as Milton Friedman, John Kenneth Galbraith, Franco Modigliani, Don Patinkin, and Robert Solow, there are general correspondence folders in which a variety of documents are chronologically arranged. There is also a large group of files relating to the publication of his textbooks. Additional correspondence can be found in almost all the other series.

A large series of Unpublished Writings contains many folders of unpublished articles, extensive research notes, jotted-down insights, and other fragmentary writings. The earliest pieces appear to be a typescript of Samuelson's 1933 diary and writings on collective bargaining (1933-1934). The wide range of topics in economic theory as well as the history of economics reflects Samuelson's interests over many decades, beginning with his work on Marx and the Transformation Problem, and later on, focusing more specifically on financial economics. The unpublished writings also reveal that he also wrote extensively on population and gender studies, thermodynamics, and mathematics.

The equally large Printed Material series houses a nearly complete collection of Samuelson's published articles in addition to a few of his monographs. In some cases, article folders include extensive correspondence between Samuelson and his editors and publishers. Located in this series is a copy of the thesis that Samuelson wrote while he was at Harvard University, which in 1947 was published as the well-known Foundations of Economic Analysis. Also present in this series are the many columns and articles he wrote for Newsweek in the 1960s and 1970s.

Other aspects of Samuelson's career can be found in course files that form the Teaching series, most of which contain reading lists and syllabi, and in the Committees and Projects series, which contains information on his many consultancy roles, grant-funded projects, and professional service. Examples include projects for the Radiation Laboratory and the Rand Corporation, and contributions to government agencies such as the US War Production Board and the Federal Reserve Board, as well as academic organizations such as the National Science Foundation, the National Academy of Science, and the Econometric Society.

The smallest series of the collection, the Awards series contains materials relating to Samuelson's Nobel Prize in Economics in 1970 and his Medal of Science award in 1996, as well as several honorary doctorates that he received. Files contain congratulatory letters and telegrams and his outgoing correspondence to subsequent Nobel Prize winners. In contrast to this small series, the large Speeches and Interviews series houses paper drafts or transcripts of nearly all of Samuelson's public presentations, amounting to over 400 lectures, speeches, and interviews. Some of these can also be found on recorded media in the Audiovisual Material series.

The Audiovisual Material series features 320 cassettes from the commercially produced "Economics Cassettes Series," a set of interviews with Milton Friedman and Paul Samuelson on economics issues of the times. There are also a few tapes and cassettes of lectures and speeches by Samuelson. Items related to the topics and events represented in this series are also found in the Teaching, Speeches and Interviews, and Awards series. There is a DVD recording of the 2010 MIT memorial service which provides many images of Samuelson taken throughout his life, filling in for the absence of photographs in the collection.

Randall Hinshaw (1915-1997) was a professor of economics at the Claremont Graduate School. This collection primarily documents his professional life through his correspondence, writings, research, professional activities, and teaching. It was acquired as part of the Economists' Papers Archive.

The Randall Hinshaw papers document his professional life as a government economist then academic economist from 1942 until his death in 1997. The most common types of material are correspondence files, typed manuscripts documenting his writings, and files of his professional activities. The collection also includes some handwritten notes and data, and teaching files. There are 88 audiocassettes, 43 quarter-inch open-reel tapes, and two VHS tapes, most of which contain audio recordings of the Bologna Claremont Monetary Conferences organized by Hinshaw. The transcripts of these tapes were published in lightly edited conference proceedings, and can be found in the series of the same name. One tape containing an audio letter from his half-brother Harvey Hinshaw and his family has been digitized, and the electronic files are available.

The primary subject of the collection is the international monetary and financial system, which is documented in Hinshaw's activities as a federal employee and university faculty member. His activities as a government economist included unpublished reports written for the Federal Reserve System and for US agencies working on the European postwar reconstruction. International negotiations on exchange rates, and the role played in this respect by financial institutions (especially the International Monetary Fund), feature prominently in both Hinshaw's writings and in the writings by others that he kept. The monetary policies of industrial countries and the influence of these policies on international trade is another subject that can be found in the collection, such as in the files documenting the discussions held during the Bologna Claremont Monetary Conferences.

Hinshaw's correspondents include several Nobel Prize economists who attended his conferences, most notably Paul Samuelson. Other frequent correspondents include Gottfried Haberler, Charles P. Kindleberger, Lionel McKenzie, Lionel Robbins, and Robert Triffin. There are obituaries and an audio recording of a memorial for his colleague Willard Thorp in the Personal series, along with material on Hinshaw's family.

Robert Summers (1922-2012) was a professor emeritus of economics at the University of Pennsylvania. This collection consists of selected writings and personal items. It forms parts of the Economists' Papers Archive.

This collection documents a selection of Summers' academic and professional writings. It provides an overview of his writings on macroeconomics, inflation, national income accounting, capacity utilization, and econometrics. His writings also document his collaborations with other prominent economists, including Lawrence R. Klein and Thomas Marschak.

Summers is noted for his research on international price comparisons and his contributions to the International Comparison Program and the widely used Penn World Tables.

Along with his own scholarship, this collection documents Summers' familial connections to other prominent economists: his wife Anita Arrow Summers, his brother Paul A. Samuelson, his son Lawrence H. Summers, and his brother-in-law Kenneth J. Arrow.

Wolfgang Stolper (1912-2002) was a professor emeritus of economics at the University of Michigan. This collection documents his professional life through his correspondence, writings, research, and professional and faculty activities (especially his missions to Africa as an economic advisor). It forms part of the Economists' Papers Archive.

Most of this collection is comprised of Stolper's files and notes from his work in Nigeria, Tunisia, and other missions to Africa. These work files document his career as a practitioner--literally working "in the field"--of development economics.

The Nigeria Series, the first and largest, contains his work files from his job as head of the Economic Planning Unit (EPU) in the Federal Ministry of Economic Development in Lagos, Nigeria from 1961-62 (sent there under the auspices of the Ford Foundation). As head of the EPU, Stolper co-authored the first ever National Development Plan, (1962-68) for the Federation of Nigeria. As such, his papers present an extensive and thorough picture of the Nigerian economy at that time. Once top secret files, they include detailed statistical data on each industry, industrialization plans, reports on marketing board policies, maps, and demographics data. Of great interest to researchers on the Nigerian economy might be Stolper's personal diary, a 393-page typewritten account of his two years in Nigeria.

The next two series pertain to his work in Tunisia (1972) and other economic missions to Africa, including Dahomey (now Benin) and Togo (1967), Benin (1983), and Malawi (1981). He was sent to these countries under the auspices of USAID, the UN, and the International Bank for Reconstruction and Development (IBRD, also known as the World Bank). The files from these three series alone make up eight of the fourteen storage boxes that house the entire collection. Also in the collection are some notes, papers and drafts of Professor Stolper's work pertaining to Joseph Schumpeter.

Stolper's name is perhaps most recognizable for the theoretical piece written with Paul Samuelson on what has come to be known as the Stolper-Samuelson Theorem (see "Protection and Real Wages," Review of Economic Studies, November 1941). This theorem, one of the core results of the Hecksher-Ohlin model of international trade, essentially states that an increase in the relative domestic price of a good (for example, via the imposition of a tariff) unambiguously raises the real return to the factor of production used intensively in producing that good (and lowers the real return to the other factor). This paper analyzed precisely for the first time the effect of trade or protection on real wages. At present, there is nothing (aside from reprints of the article) in this collection of papers dealing with the Stolper-Samuelson Theorem.

The fourth series, Writings, contains notes, drafts, manuscripts and reprints of any articles found in the collection but excluding those related to Joseph Schumpeter. Some highlights include drafts of "Investments in Africa South of the Sahara," notes and drafts of his book Planning Without Facts: Lessons in Resource Allocation from Nigeria's Development, and articles on smuggling in Africa.

The fifth series, Speeches, Lectures and Conferences, contains material (excluding those pertaining to Schumpeter) from public speaking engagements and conferences attended by Professor Stolper. One item that might be of interest is a speech recorded on magnetic tape titled "Problems of our Foreign Aid Program" that dates from around the 1950s.

Another of Professor Stolper's research interests is the history of economic thought, and this collection's Schumpeter series contains some notes, papers and drafts of Professor Stolper's work pertaining to Joseph Alois Schumpeter. Stolper was afforded a unique and personal relationship with Schumpeter, studying under him first at the University of Bonn and then at Harvard, and also through Schumpeter's position as a close friend of Gustav and Toni Stolper (Wolfgang's father and stepmother, respectively). Included in this series is a book (in German) that Professor Stolper co-wrote with Horst Claus Recktenwald and Frederic M. Scherer titled Uber Schumpeters »Theorie der wirtschaftlichen Entwicklung« (1988).
