A chance to study at M.I.T. under the rising star of the period - Paul A. Samuelson - was an unforgettable experience.
After my first visit to Japan, in 1960, to work on a joint model building project at Osaka University, I maintained a continuing interest in the country and the entire Far East.
Although I was not aware of it at the time, the experience of growing up during the Great Depression was to have a profound impact on my intellectual and professional career.
An early fascination with higher mathematics at the university level blossomed into speculative thinking that could provide a basis for dealing with economic issues.
Collegiate life subsequently gave me a basis for understanding this experience and to develop some analytical skills for dealing with the important economic aspects of this era, as well as the exciting times that were to come - World War II, postwar reconstruction, and expansion.
During my years at Pennsylvania, I have traveled widely, working on modeling projects for many countries - Japan, Israel, and Mexico, in particular.
During the early 1960s, I decided to supplement research support for quantitative economic studies at Pennsylvania by selling econometric forecasts to private and public sector buyers.
Finally, I returned to America to join the faculty of the University of Pennsylvania, which has been my professional home ever since 1958.
I have had additional reasons for visiting Austria to participate on the research program of the International Institute of Applied Systems Analysis.
I, Lawrence Klein, was born in Omaha, Nebraska, as were my elder brother and younger sister.
It came as a surprise to find that a professional society and journal (Econometrica) were flourishing, and I entered this area of study with great enthusiasm.
Leo Byron Klein and Blanche (Monheit) Klein, both of whom were born in the American Middle West, had three children.
My early education was in the public school system of Omaha, where, retrospectively, I realize that my high school training served me in good stead for the basic subjects of mathematics, English, foreign languages and history.
On the way from Chicago, I spent the summer of 1947 in Ottawa, helping to build the first of a series of econometric models for the Canadian government.
Over the years, I have often consulted with public officials on economic matters, both domestic and foreign, including international bodies.
The completion of my undergraduate training at the University of California (Berkeley) provided just the needed touches of rigor at advanced levels in both economics and mathematics.
The funds from the sale were put into research and general teaching budgets at the university. Wharton Econometric Forecasting Associates, Inc., is now a growing enterprise with many model and other econometric facilities.
The parallel development with the series of Wharton models continued and benefitted from the transferenee of research results from the SSRC project, which had, meanwhile, moved to the Brookings Institution.
The SSRC committee turned attention from team research for building a model of the United States to doing one for world trade in order to investigate the international transmission mechanism.
There I initiated a series of models that were to become known as the Wharton Models.
