Clopper Almon

Clopper Almon is the founder of Inforum, which he began at the University of Maryland soon after leaving Harvard in 1966. Dr. Almon has been a pioneer in developing macroeconomic and interindustry models, as well as software for econometric analysis and model building. His latest book, The Craft of Economic Modeling, teaches model building through hands-on experience with his econometric software package, called G7. Dr. Almon has pushed strongly through the years to make Inforum truly an international organization, forging links with other organizations in many countries who have become Inforum partners. He has designed and written a software package called Interdyme, which provides an object-oriented environment for the development of interindustry models. Clopper retired from full-time teaching in 2003 and now is Professor Emeritus in the Economics Department at the University of Maryland. He remains the director of Inforum and the chairman of the IERF Board.

His thesis was entitled An Input-Output Forecasting Model of the Japanese Economy, and was completed in 1976. After returning to Korea, Young Sun taught at Yonsei University for twenty-five years. Young Sun became the President of Hallym University in Chuncheon, South Korea in April of 2008.

Douglas Nyhus

Doug described in his thesis a world trade model which would be linked by bilateral trade flows and commodity prices by country. Such a model was not actually developed until the 1990s, but Doug's thesis helped provide the motivation for the development of the Inforum International System. The thesis, The Trade Model of a Dynamic World Input-Output Forecasting System was completed in 1975. Doug is still with Inforum.
