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...

Solow has repeatedly called for the development of models that combine equilibrium and out-of equilibrium outcomes or what he called a macroeconomics of the medium-run. This paper recounts the history of Solow’s different attempts to address this issue. It starts in early 1950s when Solow...

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...
