Much of my work in this period was concerned with exploring the logic of economic models, but also with attempting to reconcile the models with every day observation.

My research in this period centered around growth, technical change, and income distribution, both how growth affected the distribution of income and how the distribution of income affected growth.

My job was to teach the whole corpus of economic theory, but there were two subjects in which I was especially interested, namely, the economics of mass unemployment and international economics.

At the time, my personal research objectives were to provide Keynesian economics with more rigorous foundations and to tighten and elaborate the logic of macroeconomic and monetary theory.

I think what Bob Shiller and I are doing is we're focusing on macroeconomics and the role of psychology in macroeconomics.

I had become interested in economics, an interest that was transformed into a lifetime dedication when I met with the mathematical theory of general economic equilibrium.

Unemployment determination in a modern economy was the main subject area of my research from the mid-1960s to the end of the 1970s and again from the mid-1980s to the early 1990s.

The scientific study of labor economics provided the opportunity for me to unite theory with evidence my lifetime intellectual passion.

My research interests since then have shifted strongly towards the economic and regulatory problems of the financial services industry, and especially of the securities and options exchanges.

I work with the macro economy, which involves the major variables that measure the health of the whole economy, such as total consumption, investment, income, employment, and inflation.
