Abstract

This paper offers a pedagogical alternative to the familiar Keynesian analysis of leakages and injections based on the Classical school. In doing so, the paper posits that the Classical analysis provides a mirror image of the Keynesian approach, i.e., where the flows constituting leakages in the Keynesian system are analogous to injections in the Classical school. Furthermore, the paper shows that a disequilibrium situation in the bond market causes bond prices to move in a direction precisely opposite that of real gross domestic product when a similar goods market disequilibrium occur.
