How Magical is the Keynesian Multiplier?
For most economists and financial commentators, the heart of economic growth is the increase in the demand for goods and services. The view is that increases or decreases in demand are behind rises and declines in the economy’s production of goods and services. It is also held that the economy’s total output increases by a multiple of the change in expenditure by government, consumers, or businesses.
An example will illustrate how an increase in spending raises overall output by a multiple of this spending.
