Early thoughtsMy first encounter with post-Keynesian growth theory was during the 1975-76 Honours Seminar in Modern Classics, which was a compulsory full-year undergraduate course in Economics at Carleton University, located in Ottawa, given by Thomas K. Rymes. The Seminar touched diverse fields in economics, ranging from Walrasian exchange and production theory, as well as neoclassical growth theory, and then moving on to the monetary framework with Keynes, Patinkin, Clower, Leijonhufvud and Friedman. Other professors also gave occasional lectures, for instance on the theory of the firm, the principal/agent distinction, shirking by workers and the theory of capital markets. Rymes had done his PhD at McGill University, in Montreal, which at the time and until the early 1980s was the main centre of Cambridge-style Keynesian economics, from which Canadian colleagues such as Mario Seccareccia, Louis-Philippe Rochon, Omar Hamouda, Gilles Dostaler and Morris Altman graduated at either the MA or PhD level. Rymes devoted two lectures to the Cambridge capital controversies (reswitching and capital reversals in two-sector models) and productivity accounting in December 1975. I only found out a year later, when browsing through shelves in a London bookstore, that he had written a whole book on the Cambridge controversies and its implications for productivity measurement, with a very favourable preface by none other than Joan Robinson (Rymes, 1971). He started the 1976 lectures by tackling Harrod's growth model and the neo-Keynesian or neo-Cambridgian models as they were then called. These were the models proposed in the mid-1950s and early 1960s by Joan Robinson, Nicholas Kaldor and Luigi Pasinetti.Like many students, I suppose, I was fascinated and puzzled by Pasinetti's long-run solution to the macroeconomic determination of the profit rate, r = g/s c , which only depended on the growth rate of the economy and the propensity to save of capitalists, regardless of the propensity to save of workers. So much so that when I moved to the University of Paris 1 Panthéon-Sorbonne for my graduate studies in the Fall of 1976, my first major paper was devoted to 'L'introduction de la firme et de la finance dans le modèle de croissance et répartition de Pasinetti' (The introduction of the firm and of finance in Pasinetti's model of growth and distribution), which also discussed Kaldor's neo-Pasinetti theorem. I elected to write my doctoral dissertation on a topic closer to monetary economics, however, and so my main interest became the post-Keynesian theory of endogenous money. When I got a position at the University of Ottawa (first, as a temporary position in 1979, then a tenure-track one in 1981), I opted to teach the graduate course in growth economics, and my lecture notes gave rise to my 1987 book, Macroéconomie: Théories et controverses postkeynésiennes (Macroeconomics: Post-Keynesian Theories and Controversies), which dealt with the Cambridge controversies, in particular its implications for the measurement of technical progr...
