The conventional wisdom about Keynes's Principle of Effective Demand is that it states something about quantities. It is widely held that the Principle determines the levels of output and employment in a world not governed by Say's Law. This paper argues that the Principle of Effective Demand...

Keynes's essay "Relative Movements of Real Wages and Output" is widely believed to be an important amendment to his General Theory because, in this essay, Keynes relaxed his core assumption of decreasing marginal returns to labour. Non-decreasing marginal returns, however, do not sit comfortably...

Keynes introduces the term 'effective demand' in chapter 3 of the General Theory as designating the point of intersection of two functions: the 'aggregate demand function' (D) and the 'aggregate supply function' (Z). For the first time in the literature, I here specify exact functional forms for...

The paper suggests a consistent interpretation for the much debated Z-footnote on pp. 55-56 of the General Theory and discards claims recently made in the literature concerning the importance of output heterogeneity for Keynes's macroeconomic approach.

This paper is a contribution to a symposium mutually reviewing papers on Keynes's principle of effective demand as set out in The General Theory, by Allain (2009. Effective demand and short-term adjustments in the General Theory, Review of Political Economy, vol. 21, 1–22), Hartwig (2007....

This Symposium consists of individual comments by three authors on papers previously published by the other two (Allain, 2009, Hartwig, 2007 and Hayes, 2007) on the topic of Keynes’s principle of effective demand as set out in The General Theory. The Symposium includes updated versions of PKSG...
