This article is based on Kalecki's * 1934 study entitled 'Three Systems'. It aims to show that before the General Theory Kalecki developed a mathematical model capable of expressing both the main conclusions of the neoclassical theory - Kalecki's Systems I and II - and the persistence of...

Oskar Lange's 1938 article "The Rate of Interest and the Optimum Propensity to Consume" is usually associated with the original IS-LM approach of the late 1930s. However, Lange's article was not only an attempt to illuminate Keynes's main innovations but the first part of a wide project that...

In The Trade Cycle, Roy Harrod [1936a] propounded the Law of Diminishing Elasticity of Demand. The present paper tries to clarify the precise role Harrod assigned to this law in his The Trade Cycle Theory. We discuss the micro and macro foundations of the Law of Diminishing Elasticity of Demand...

Business cycles and growth are considered as independent fields for decades. Indeed, after the Second World War, when macroeconomics began to develop through an increased use of mathematical models, the problem of analyzing growth-cycles dynamics appeared as a real (and certainly also...

In The Trade Cycle, Roy Harrod [1936a] propounded the Law of Diminishing Elasticity of Demand. The present paper tries to clarify the precise role Harrod assigned to this law in order to understand his trade cycle theory. We discuss the micro and macro foundations of the Law of Diminishing...

There is a short period, at the eve of the Second World War, where the development of macroeconomic theory pushed imperfect competition to the fore. During this period called by Shackle the ‘years of high theory’, many issues concerning income distribution and the trade cycle were raised....

The present study centres on Meade's Simplified Keynesian Model (1937) presented in 1936. The objective of this paper is to show that Meade's model foreshadows the studies (Kalecki (1944), Tobin (1975)) which refute wage rigidity as the benchmark between Keynesian and Classical models. In...

In this short note, we wonder on the opportunity to express Keynes's central message with a static model. Because the phenomena described by Keynes are dynamic, especially the ones described in chapter 19 of the General Theory, we think that they must be analysed with a dynamic model. Deciding...
