It is an important tool of income propagation and business cycle analysis. This example gives us what may be described as a ‘motion picture’ of income propagation under certain assumptions. We see that the whole of the increment in income is not spent on consumption nor is it entirely saved. In the U.S. again, there are immediate needs to repair roads and bridges, rebuild the energy grid, and modernize other means of travel. It is so called because it assumes no time lag between the initial change in autonomous investment and ultimate change in income. Kahn. Please try again later. It is, therefore, highly desirable that to have the desired results of multiplier, these leakages should be plugged. It can never be one because consumption always increases when income increases (i.e., MPC is never zero). Instead, he advocated higher government spending financed by higher borrowing. To foster new economic thinking, we host convenings that gather together a diverse community of thinkers from different fields, countries, and schools of thought. Prof. Hazlitt has also criticized the concept of multiplier rather bitterly. Keynes believed that the initial increment in investment increases the final income by many times.
