Macro Flashcards
What does aggregate demand mean
Total demand for goods + services in the economy
How do you calculate AD
AD = C + I + G + (X-M)
What does AD take into account
Consumer spending (C)
Investment spending (I)
Government spending(G)
Imports(X)
Exports(M)
What is the wealth effect
As price level decreases purchasing power of income increases
People are richer so spend more money
What is the trade effect (X-M)
As price levels decreases purchasing power exports become more competitive but imports become less competitive
Greater demand for exports so increase in revenue (increasing X)
Importantes become less competitive less spending on imports (M decreases)
What is the interest effect
As prive level decreases interest rates can be kept lower
If inflation is low then interest reates can be kept lower
Higher investment + spending
Reduces value of exchange rate
Why does AD shift
When C I G or (X-M) change independent of prive level
What happens to AD as price increases
At higher price levels CP(current price) consumers have less disposable income(money to spend)
High level UK exports will be relatively less competitive leading to lower exports
Shift in the AD is caused when real income
Higher income shifts AD to the right
What can cause a shift in AD
An increase in income leads to a shift right
Rise in investment exports or government spending
What determines consumer spending
Disposable income
Saving
Consumer confidence
House prices/wealth
Income tax/VAT
Interest rates
Cost of living
What is disposable income
Income after taxes + benefits
What effect does higher disposable income have on AD
Rising real wages would increase disposable income
And shift AD to the right
What effect does saving have on AD
If income stays constant but consumers want to increase their savings then consumption will fall
What effect does consumer confidence have on AD
If consumer are pessimistic about the future they will prefer to save pay off debt + reduce their current spending
Low confidence will shift AD to left
High confidence will encourage spending
What effect does house prices have on/ wealth have on consumer spending
Rising house prices tend to increase consumer spending through a positive wealth effect
If house prices rise
They could gain equity withdrawal
Re-mortgaging house + taking money to spend
They will also feel more confident if their house is worth more
What effect does income Tax/Vat do to consumer spending
A cut to income tax will increase the consumers disposable income encouraging spending
What effect does interest rates have on consumer spending
Lower interest rates reduce the cost of borrowing and encourage spending
Lower rates also make consumption more attractive than saving in the bank
How does cost of living cause an increase consumer spending
If wages stay the same cost of living goes down people will have more disposable income + spend more
What effect does investment have
Effects AD + AS is relatively more volatile is strongly influenced by confidence + changes in rate of economic growth
What factors affect investment
Confidence
Animal spirts
Interest rates
Availability of finance
Government regulation
Economic growth
How does confidence affect investment
If business are optimistic about future demand they will increase productive capacity and invest now
Business face uncertainty they will cut back on risky investments
How do animal spirits effect investment
Do people expect there business to grow
How does interest rate effect investment
Investment if often financed by borrowing or using savings
Lower interests rates make it cheaper to finance investment + make more projects worthwhile
