Keynesian Model and Macroeconomic policy - Essay Example This essay outlines main foundations of the theory of John Maynand Keynes, one of the most renowned economic thinker of all time. According to his theory, aggregate demand is subject to periodic changes caused by changes in the determinants of aggregate demand.Aggregate demand is unstable because prices and wages are downwardly inflexible. This decline has no effect on price level but real output falls and can remain at its equilibrium indefinitely. It is necessary for governments to intervene and manage the level of demand in the economy in order to obtain and retain full employment. In other words, unless careful measures are taken to offset increase in aggregate demand, real output may remain below full employment. At times of recession, high unemployment levels, and low investments in new equipments and machinery together with low levels of technology characterize the economy.
