The «Keynesian multiplier» has important implications for policy. The effect on demand of any exogenous increase in spending, such as an increase in government outlays is a multiple of that increase – until potential is reached. Thus, a government could stimulate a great deal of new production with a modest outlay: if the government spends, the people who receive this money then spend most on consumption goods and save the rest. This extra spending allows businesses to hire more people and pay them, which in turn allows a further increase in consumer spending. This process continues. At each step, the increase in spending is smaller than in the previous step, so that the multiplier process tapers off and allows the attainment of equilibrium.
