on Post Keynesian Economics |
| 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. |

| Abstract: | In this paper we discuss possible explanations for persistent global inequalities from a political economy perspective. Different from what Smith and Marx assume in the long period method – that both capital and labor are fully mobile – we assume that labor is not mobile across regions. The lack of labor mobility is an important abstract problem to theorize about capitalist development in a globalized context. Including such assumption in the dual problem of consumption-growth and wage-profit rate, the model sheds light on some channels in which uneven development and specialization may occur: different wages and equalized profit rates can be achieved by different labor qualities or different access to technologies. If labor qualities are different, wage differences would represent only the difference in labor productivity and effective wages would be equalized, without any specialization. If technologies are different, on the other hand, specialization may occur, and trade is thus established. The lack of technological mobility can occur due to increasing returns to scale, product differentiation and different socioeconomic characteristics of countries. |

| Abstract: | Undergraduate textbooks present the IS-LM model in a way that leaves open three questions. (1) How does the government fund a fiscal stimulus in the IS-LM model? (2) Given the unchanged money supply: What money do economic actors use to buy the extra output that a fiscal stimulus brings? (3) What is the appropriate money measure and interest rate for the IS-LM model? To help with those questions, the paper suggests a visual model of fiscal policy that can be seen as a long-form version of the IS-LM model – a long-form version that still contains answers to the three questions. |
