This process of decrease in output & income will continue until the economy reaches the equilibrium level where AD=AS. because the medium run equilibrium is e cient and the medium run can be understood as a special case of the short run, the policy implications in the short run become immediately clear.

The coefficient (1-b) measures the slope of the saving function. The value of APS can be negative when the value of consumption exceeds the value of income. Equilibrium is achieved when planned saving is equal to planned investment that is S=I. Investment means addition to the stock of capital good, in the nature of structures, equipment or inventory.

At a fixed price the value of ex-ante aggregate demand for final goods is the sum of ex-ante consumption expenditure C and ex-ante investment expenditure I on final goods. At equilibrium point the equilibrium values of output and aggregate demand are OY1 and AD1. Under these circumstances equilibrium output will be determined by aggregate demand at this price in the economy. . The corresponding level of saving is -0A. . At OB level of income consumption is equal to income, so saving are zero. endstream
Multiplier tells us what will be the final change in the income, as a result of change in investment. There is direct relationship between k and MPC. stream
Thus AED always corresponds to the equilibrium level of income / output in the economy This is known as effective demand principle as equilibrium output is determined by the AD ( at a fixed price of final goods and constant rate of interest in the economy) so B is another point on saving curve . .
