This link between investment and the rate of change of demand is called the accelerator theory. Because people spend most of the extra income they get, money flows through the economy one person at a time, like a ripple effect when a rock gets thrown into the water.

Another important assumption in the theory of multiplier is that excess capacity exists in the consumer goods industries so that when the demand for them increases, more amounts of consumer goods can be produced to meet this demand. The following general formula to calculate the multiplier uses marginal propensities, as follows: multiplier 1 1 - mpc Hence, if consumers spend 0. The higher is the propensity to consume domestically produced goods and services, the greater is the multiplier effect.

Thus, as a result of negative effects of rise in price level on real wealth, private investment and net exports, in the upper panel a of Fig. For example, suppose variable x changes by 1 unit, which causes another variable y to change by M units. If as a result of the investment of Rs. In this way increase in demand resulting from investment would not lead to rise in prices but will cause real output to rise.
