Vernon Wesley Ruttan
Vernon Wesley Ruttan (1924–2008) was a well-known development economist at the University of Minnesota, where he was Regents Professor Emeritus in the Departments of Economics and Applied Economics. Ruttan's research focused on agricultural development, induced innovation, technical change and productivity growth, institutions, and development assistance policy. His book with Yujiro Hayami, Agricultural Development: An International Perspective was considered a classic in the field and was translated into four other languages.
Education and early career
Ruttan held positions earlier in his career at the Tennessee Valley Authority, Purdue University, the President's Council of Economic Advisors, the Rockefeller Foundation at the International Rice Research Institute in The Philippines, and President of the Agricultural Development Council.
Induced Innovation and Agricultural Development
In the book, Agricultural Development: An International Perspective, Ruttan and Hayami outline their hypothesis as follows:
"The [induced innovation] model attempts to make more explicit the process by which technical and instititutional changes are induced through the responses of farmers, agribusiness entrepreneurs, scientists, and public administrators to resource endowments and to changes in the supply and demand of factors and products. The state of relative endowments and accumulation of the two primary resources, land and labor, is a critical element in determining a viable patterns of technical change in agriculture. Agriculture is characterized by much stronger constraints of land on production than most other sectors of the economy. Agricultural growth may be viewed as a process of easing the constraints on production imposed by inelastic supplies of land and labor. Depending on the relative scarcity of land and labor, technical change embodied in new and more productive inputs may be induced primarily either (a) to save labor or (b) to save land." (Hayami and Ruttan, 2nd ed., p. 4).
The Role of Government Investment in the Development of General Purpose Technologies
In his book, Is War Necessary for Economic Growth?, available in short form through the lecture of the of the same title Professor Ruttan argues that large scale and long term government investment is necessary for the development of general purpose technologies and economic growth. He analyzed the development of six different technology complexes and concluded that government investments have been important in speeding up the development of all of these, and that nuclear power would, most probably, not have been developed at all in the absence of large government investments in development.
The six technologies that were analyzed by Ruttan are:
- The American production system
- Airplane technologies
- Space technologies
- IT technologies
- Internet technologies
- Nuclear power
Ruttan was a Fellow of the American Agricultural Economics Association, American Association for the Advancement of Science, and the American Academy of Arts and Sciences. He was elected as a member in the National Academy of Sciences in 1990.
Ruttan also received honorary degrees from Rutgers University, Purdue University, and Christian Albrechts University of Kiel. Ruttan received the U.S. Department of Agriculture Distinguished Service Award and the Alexander von Humboldt Award for outstanding contributions to agriculture.
