I am interested in the economics of the less developed countries and have focussed mainly on positive analysis. Preferring to work within a well-specified framework, I did much of my early work in the context of a single country, Brazil. That research included an industry study (on an industry whose rapid development raised questions concerning some accepted assumptions in the field of development economics), and a book on economic policy-making.
That work led to research on macroeconomic and trade problems. Subsequent papers have focussed on savings behavior, macroeconomic adjustment, transfer of technology, industrial organization and entrepreneurship. I have found economic theory a very useful tool for understanding less developed economies.
In addition, I have found historical studies valuable for clarifying the analytics of long-term development. In that vein, I have done a two-volume study of Brazil’s economic experience in the 125 years between Independence and World War II. This time span raises interesting analytical questions, for it includes both a long period of relative stagnation and the shift (circa 1900) to sustained, rapid development. More recently, I have been working on macroeconomic adjustment, on approaches to investment choice and on the use of research.
