This topic focuses on how policy shifts aggregate demand. Questions trace how an increase in government purchases raises incomes, which then raises money demand and interest rates, causing the crowding-out effect on investment. You will also calculate the multiplier effect, where an initial rise in spending leads to a larger rise in total demand, and see how waves of pessimism shift aggregate demand to the left. Graph items show money demand with the interest rate on the vertical axis. Questions on the Eurozone link these ideas to currency unions. These concepts appear often in macroeconomics papers.

The crowding-out effect occurs when expansionary fiscal policy raises interest rates and reduces private investment. Higher government spending increases income and money demand, which pushes up interest rates. Firms and households then borrow less, so part of the boost to aggregate demand from government purchases is offset.
The multiplier effect means that an increase in government spending raises total demand by more than the initial amount. Extra spending becomes income for others, who spend part of it, creating further rounds of spending. A simple multiplier equals 1 divided by 1 minus the marginal propensity to consume, so a higher MPC gives a larger multiplier.
