1. Convergence on inflation and divergence on price-control among Post-Keynesian pioneers: insights from Galbraith and Lerner

   By:	Alexandre Chirat; Basile Clerc
   Abstract:	This article proposes a historical and analytical reconstruction of a debate that never happened between John Kenneth Galbraith and Abba Lerner over the issue of price controls. While they adopted a similar analysis of underemployment inflation, shared by many post Keynesians, Lerner and Galbraith remained fundamentally opposed as to the effectiveness of price controls. Indeed, while both agreed on the relevance of price controls in the specific context of World War II, they disagreed over including price controls within the conventional framework of economic policies, as illustrated by their respective stances in the debate surrounding the stagflation of the 1970s. Throughout the paper, we provide the rationales behind their divergence on price controls by investigating its theoretical, epistemological, and normative roots. Finally, we put into perspective the contemporary debates about price control in the context of resurgent inflationary pressures with some salient points drawn from our reconstruction of the debate that opposed these two pioneering post Keynesians economists.

2. Solving Vincent Carret's Puzzle: A Rebuttal of Carret's Fallacies and Errors

   By:	Jean-Marc Ginoux; Franck Jovanovic (TELUQ - Université Téluq)
   Abstract:	The present rejoinder aims at rebutting Carret's allegation of mistaken interpretation in our work. We expose mathematical errors in Carret's work, also present in his publications with Assous. Then, and most importantly, we show the unfounded economic consequences that follow from erroneous mathematical assumptions about Frisch's model. We demonstrate that Carret's statements are based on a misunderstanding of Frisch's econometric model and approach. Then, we show that Carret's results are not supported by the demonstration he claims to have made, and that he misrepresents the arguments of some authors, making them say things they never said. In a recent article that gave birth to a mini-symposium, we propose a solution to a controversy about Frisch's work opened 30 years ago by Stefano Zambelli (Ginoux and Jovanovic 2022c). In 1992 and 2007, Zambelli published a numerical analysis of one of the models developed by Frisch in his seminal book chapter "Propagation problems and impulse problems in dynamic economics." In the conclusion of his work, supported by his numerical analysis, Zambelli claimed that Frisch's "rocking horse model is not rocking!" Since then, several authors have taken up this conclusion
