The AI that runs your actuarial department has calculated that, at any price level, Centauri's aggregate demand has the equation AD = 0.75(Y – T) + G, where Y is real GDP, T is total taxes, I is investment and G is government spending. Everything is measured in billions of 2099 Cents (denoted C). The government reports that taxes are T = 60 and government expenditures are G = 205. a) By how much will a 10-Cent decrease in taxes T increase Aggregate Demand? b) By how much will a 10-Cent increase in government spending G increase Aggregate Demand?. c) Which policy is a more effective way to change Aggregate Demand? d) Determine a policy that will return the Centauri economy to its long-run equilibrium. That is, figure out a combination of changes to taxes and government spending that gets AD back to 700. For now, ignore what will happen to the price level.
