The papers of Wolfgang F. Stolper span the period from 1947-1988, with the bulk of the material dated between 1960 and the mid 1970s. Most of the collection is comprised of Professor 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 papers are organized into eight series: Nigeria; Tunisia; Other Missions; Writings; Speeches, Lectures, and Conferences; Schumpeter; University of Michigan and Teaching Material; and General Correspondence. 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 1962-68for 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. The collection as a whole is restricted, so that persons interested in viewing the papers during Professor Stolper's lifetime must first obtain his permission.

Stolper's name is perhaps most recognizable for the theoretical piece written with Paul A. Samuelson on what has come to be known as the Stolper-Samuelson Theorem (see Nov. 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 notes and drafts of his book 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 that dates from around the 1950's.

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 1988.

The addition (02-0207) (8625 items, 14 linear feet; dated 1892-2001) contains correspondence with colleagues, including Paul Samuelson, Gottfried Haberler, and other prominent economists; class lectures (1930s); as well as writings about J. A. Schumpeter, economic development, and other topics. Also writings, reports, diaries, and other documents (mainly 1960s) about the economies of Nigeria, Tunisia, Liberia, Togo, and the Ivory Coast. In addition, there are 12 black-and-white and 18 color photographs; one x-ray; and 16 electronic documents on 3 floppy disks. This addition is unprocessed.
