(Remarks given at the Klein Legacy Dinner, October 24, 2014, Lower Egyptian Gallery, University of Pennsylvania Museum of Archaeology and Anthropology.)
I owe an immense debt of
gratitude to Larry Klein, who helped guide, support and inspire my career for more than three
decades. Let me offer just a few vignettes.
Circa
1979 I was an undergraduate studying finance and economics at Penn's Wharton
School, where I had my first economics job. I was as a research assistant at
Larry's firm, Wharton Econometric Forecasting Associates (WEFA). I didn't know
Larry at the time; I got the job via a professor whose course I had taken, who
was a friend of a friend of Larry's. I worked for a year or so, perhaps ten or
fifteen hours per week, on regional electricity demand modeling and
forecasting. Down the hall were the
U.S. quarterly and annual modeling groups, where I eventually moved and spent
another year. Lots of fascinating people roamed the maze of cubicles, from eccentric
genius-at-large Mike McCarthy, to Larry and Sonia Klein themselves, widely
revered within WEFA as god and goddess. During fall of 1980 I took Larry's
Wharton graduate macro-econometrics course and got to know him. He won the
Nobel Prize that semester, on a class day, resulting in a classroom filled with
television cameras. What a heady mix!
I
stayed at Penn for graduate studies, moving in 1981 from Wharton to Arts and
Sciences, home of the Department of Economics and Larry Klein. I have no
doubt that my decision to stay at Penn, and to move to the Economics
Department, was heavily dependent on Larry's presence there. During the summer
following my first year of the Ph.D. program, I worked on a variety of country
models for Project LINK, under the supervision Larry and another leading
modeler in the Klein tradition, Peter Pauly.
It turned out that the LINK summer job pushed me over the annual salary cap
for a graduate student -- $6000 or so 1982 dollars, if I remember correctly --
so Larry and Peter paid me the balance in kind, taking me to the Project LINK
annual meeting in Wiesbaden, Germany. More excitement, and also my first trip
abroad.
Both
Larry and Peter helped supervise my 1986 Penn Ph.D. dissertation, on ARCH
modeling of asset return volatility. I couldn't imagine a better trio of
advisors: Marc Nerlove as main advisor, with committee members Larry and Peter
(who introduced me to ARCH). I took a job at the Federal Reserve Board, with
the Special Studies Section led by Peter Tinsley, a pioneer in optimal control of macro-econometric models. Circa 1986 Larry had more Ph.D. students at the
Board than anyone else, by a wide margin. Surely that helped me land the
Special Studies job. Another Klein student, Glenn Rudebusch, also went from
Penn to the Board that year, and we wound up co-authoring a dozen
articles and
two
books over nearly thirty years. My work and lasting friendship with Glenn
trace in significant part to our melding in the Klein crucible.
I
returned to Penn in 1989 as an assistant professor. Although I have no
behind-the-scenes knowledge, it's hard to imagine that Larry's input didn't
contribute to my invitation to return. Those early years were memorable for
many things, including econometric socializing. During the 1990's my wife Susan
and I had lots of parties at our home for faculty and students. The Kleins were
often part of the group, as were Bob and Anita Summers, Herb and Helene Levine,
Bobby and Julie Mariano, Jere Behrman and Barbara Ventresco, Jerry Adams, and
many more. I recall a big party on one of Penn's annual Economics Days, which that year
celebrated The Keynesian Revolution,
Larry's landmark 1947 monograph.
The
story continues, but I'll mention just one more thing. I was honored and
humbled to deliver the Lawrence R. Klein Lecture at the 2005 Project LINK
annual meeting in Mexico City, some 25 years after Larry invited a green 22-year-old to observe the 1982 meeting in Wiesbaden.
I have
stressed guidance and support, but in closing let me not forget inspiration, which
Larry also provided for three decades, in spades. He was the ultimate scholar, focused and steady, and the ultimate gentleman, remarkably gracious under pressure.
A key
point, of course, is that it's not about what Larry provided me, whether guidance, support or inspiration -- I'm just
one member of this large group. Larry generously provided for all of us, and for thousands of others who couldn't be here tonight, enriching all our lives. Thanks Larry. We look forward to working daily to honor and advance your legacy.
