Currently, a government's budget is balanced. The marginal propensity to consume is 0_80_ The government has determined that each additional SIO billion in new government debt it issues to finance a budget deficit pushes up the market interest rate by 0_20 percentage points. It has also determined that every 0_10 (one-tenth) percentage-point change in the market interest rate generates a change in planned investment expenditures equal to $2 billion. Finally, the government knows that to close a recessionary gap and take into account the resulting change in the price level, it must generate a net rightward shift in the aggregate demand curve equal to $260 billion. Assuming that there are no direct expenditure offsets to fiscal policy, calculate the increase in government expenditures necessary to close the recessionary gap. (Hint: How much private investment spending will each SIO billion increase in government spending crowd out?) billion _ (Enter your response rounded to two decimal places.)
