- Rate of interest (higher or lower)
- Availability of credit

What does government spending include?

What is the shape of the AD curve?
Shows different quantities of total demand for an economy’s products at different prices
What happens to AD when the general price level rises?
AD contracts
What is the wealth effect?
A rise in price levels impacts how much people can buy
What is the international effect?
A rise in price level reduces demand for net exports
What is the interest rate effect?
A rise in price level increases demand for money, raising interest rates
What can cause shifts in the AD curve?
- Changes in consumer expenditure
- Changes in investment
- Changes in government spending
- Changes in net exports

- Increase in wealth
- Rise in money supply

What causes shifts in the AS curve?
- Change in price of factors of production
- Change in tax rates on firms
- Changes in factor productivity/quality
- Change in quantity of resources
