Card
What is fiscal policy?
Use of government spending (G) and taxation (T) to influence aggregate demand and achieve macroeconomic objectives.
Card
Expansionary vs contractionary fiscal policy?
Expansionary: ↑G or ↓T to boost AD (recession). Contractionary: ↓G or ↑T to reduce AD (inflationary boom).
Card
Government spending multiplier?
k = 1 ÷ (1 − MPC). A $1 increase in G causes a $k increase in national income.
Card
Tax multiplier (simplified)?
k_tax = −MPC ÷ (1 − MPC). A tax cut boosts disposable income and AD, but the effect is smaller than an equal G increase.
Card
What are automatic stabilisers?
Built-in fiscal mechanisms that stabilise AD without new legislation — progressive tax (revenue falls in recession) and unemployment benefits (spending rises).
Card
What is crowding out?
Higher G financed by borrowing raises interest rates, reducing private investment — partially offsetting the fiscal stimulus.
Card
What is fiscal policy?
The use of government spending and taxation to influence macroeconomic conditions, particularly aggregate demand, employment, inflation, and economic growth.
Card
What is the difference between a budget deficit and the national debt?
A budget deficit is a shortfall in a single year where Government Spending > Tax Revenue. The national debt is the cumulative total of all past government borrowing that has not been repaid.
Card
Explain 'crowding out'.
A situation where increased government borrowing to finance a budget deficit drives up interest rates, which in turn reduces (crowds out) private investment and consumption, weakening the effect of expansionary fiscal policy.
Card
What are automatic stabilisers?
Features of the fiscal system that automatically work to dampen economic fluctuations without new government decisions. For example, in a recession, tax revenues fall and welfare spending rises, automatically boosting aggregate demand.
Card
Why might a tax cut have a smaller multiplier effect than an equivalent increase in government spending?
Because a portion of the tax cut will be saved by households (a leakage), whereas all of an increase in government spending is a direct injection into the circular flow of income.
