Explain what is true, what is false, what is uncertain (e.g., true only under certain circumstances) in the following statement: “Consider a closed economy, where taxes are in lump-sum form. A fiscal policy that involves both government spending (G) and taxes (T) increasing simultaneously by the same amount, ΔG = ΔT > 0, will not change the budget deficit, but because of this, it will not succeed in increasing equilibrium output, not even in the short run.”
