The ET Interview: Professor H. O. A. Wold: 1908-1992 The ET Interview: Professor H. O. A. Wold: 1908-1992

David F. Hendry, Mary S. Morgan, H. O. A. Wold
Econometric Theory, Vol. 10, No. 2 (Jun., 1994), pp. 419-433

Sadly, Herman Wold died on February 16, 1992, before agreeing to the final version of this interview. We are indebted to his son, Professor Svante Wold, for his kind permission to publish. We hope that this record of our discussions with Herman Wold, who, together with his two great Norwe- gian compatriots Ragnar Frisch and Trygve Haavelmo, helped lay the sta- tistical foundations of modern econometrics, will contribute to his memory. From our personal perspective, Herman Wold was an enthusiastic suppor- ter of our early incursions into the history of econometrics (see The History of Econometric Ideas by Mary Morgan, 1990), and we know that there are many like us who will greatly miss his stimulating contributions. Herman Wold was born on Christmas day, 1908, at Skien, Norway. His family moved to a small town outside Stockholm in 1912, and he lived in Sweden for the remainder of his life. He enrolled at Stockholm University in 1927 to study physics, mathematics, and economics but switched to study- ing statistics with Harald Cramer. After his undergraduate degree, he stud- ied the theory of risk with Cramer, then worked for an insurance company for a period, returning to Stockholm University in 1936. His doctoral the- sis of 1938, A Study in the Analysis of Stationary Time Series, embodies the famous Wold Decomposition theorem. In 1942, he moved to the Chair of Statistics in Uppsala and held that post until 1970, when he went to Goteborg for five years, finally becoming Professor Emeritus at Uppsala in 1975. He became a Fellow and later President of the Econometric Society; was Vice-President of the International Statistical Institute; a Foreign Honor- ary Member of both the American Economic Association and the Ameri- can Academy of Arts and Sciences; an Honorary Fellow of the Royal Statistical Society; a member of the Swedish Royal Academy of Sciences, serving on the Nobel Prize Committee in Economics from 1968 until 1980; and was the recipient of several honorary doctorates. In retirement, he was Professeur Invite at the University of Geneva until 1980.

The ET Interview: Gregory C. Chow

Author(s): Adrian Pagan and Gregory C. Chow

Source: Econometric Theory, Vol. 11, No. 3 (Aug., 1995), pp. 597-624

Gregory Chow has been an important figure in econometrics for almost four decades. There can be few students of quantitative economics who have not been taught the "Chow test" for structural change in regression and equally few applied studies that do not report it. But Gregory's work has been much broader than this-techniques developed in papers on the stock adjustment model, dynamic responses, and control methods have all become part of the milieu of the practicing econometrician. It is notable that this work has never been "theory for theory's sake"; behind it has always been the desire to fash- ion tools that would be immediately useful for the analysis of economic data. It has also been strongly oriented toward the analysis of systems, and his interest in systems has played itself out in many ways -from simulta- neous equation estimation and analysis through control methods to prob- lems of the Chinese economy. There can be few econometricians who have made contributions across such a wide spectrum of issues.

The ET Interview: Professor Phoebus J. Dhrymes

Econometric Theory, Vol. 18, No. 5 (Oct., 2002), pp. 1221-1272
Phoebus J. Dhrymes is one of the best known econometricians of the last 40 years. He has made substantial contributions to econometric theory through articles in leading journals and by way of a series of outstanding texts on the foundations and methods of econometrics. His early research began with an applied econometric focus on problems of production and investment. His later contributions concentrated on the foundations of econometric methodology, including systems of simultaneous equations. Throughout the econometrics community, Dhrymes is well known for his influential textbooks, some of which have been translated into several languages. His 1970 book Econometrics: Sta- tistical Foundations and Applications provided an accessible and rigorous foun- dation for both students and teachers of econometrics. His subsequent books have continued to treat foundational issues and have tracked new areas of econometric interest through to his 1998 book Time Series, Unit Roots, and Cointe- gration. Reading his books reveals Dhrymes as a teacher, synthesizer, and master expositor. As he says in the interview that follows, "my books are not typical textbooks. I perceive them more as books that bridge the gap between ordinary textbooks and journal articles and as filters that distill and synthesize the wisdom of many contributors to the subject. On this score I was influ- enced in my writing by the way I learn when studying by myself."
