Q1. How does the government use the fiscal policy and monetary policy to stabilize the economy?
◆ According to the basic Keynesian model inadequate spending is an important cause of recessions. To fight recessions- at least, those caused by insufficient demand rather than slow growth of potential output- policymakers must find ways to stimulate planned spending. Policies that are used to affect planned aggregate expenditure, with the objective of eliminating output gaps, are called stabilization policies. Policy actions intended to increase planned spending and output are called expansionary policies: expansionary policy actions are normally taken when the economy is in recession. Contractionary policies are policies actions intended to reduce planned spending and output. The two major tools of stabilization policy are monetary policy and fiscal policy. -P651
For example, an increase in government purchases raises autonomous expenditure directly, so it can be used to reduce or eliminate a recessionary gap, Similarly, a cut in taxes or an increase in transfer payments increases the public 's disposable income, raising consumption spending at each level of output by an amount equal to the marginal propensity to consume times the cut in taxes or increase in transfers. Higher consumer spending, in turn, raises short-run equilibrium output.
