According to the supply-side view of fiscal policy, if the impact on tax revenues is the same, does it make any difference whether the government cuts taxes in a way that reduces marginal tax rates or in a way that does not reduce marginal tax rates?
a. No; both actions will exert the same impact on aggregate supply and demand.
b. Yes; only lower tax rates will increase the incentive to earn marginal income and thereby stimulate aggregate supply.
c. No; in both cases people will increase their saving in the expectation of higher future taxes and thereby offset the stimulus effect of lower taxes.
d. Yes; interest rates will increase if marginal tax rates are lowered, whereas they will tend to decrease if marginal tax rates are left unchanged.
