Abstract
By ‘effective demand’ Keynes meant the forces determining changes in the scale of output and employment as a whole. It was intended to replace Say’s Law. For Keynes, since entrepreneurs maximized monetary returns, not employment or physical output, there was no reason why their investment decisions should lead to an equilibrium at full employment. Since this account permitted any level of employment to emerge as a stable equilibrium, including full employment, it is more general than the classical Say’s Law position, in which the only stable equilibrium was the limit set by full employment as given in the labour market.
