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.

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.

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.

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.

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.

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.
