A Reinterpretation of the Keynesian Consumption Function and Multiplier Effect

Ryu-ichiro Murota and Yoshiyasu Ono

ISER Discussion Paper from Institute of Social and Economic Research, Osaka University

Abstract: We propose a microeconomic foundation of the multiplier effect and that of the consumption function using a dynamic optimization model that explains a shortage of aggregate demand and unemployment. We show that government purchases boost aggregate demand through a multiplier-like process but that the implication is quite different. It works through not an increase in disposable income but moderation of deflation, which makes money holding costly and stimulates consumption.
