Business cycles & Aggregate Demand/Supply Flashcards
what does full employment level mean
everyone who wants a job can get one
what is the natural level of Gdp
full employment
GDP as high as it can be (all resources used)
There is competition for resources which is causing inflation
what does ceteris paribus mean
assumption that everything but supply and demand are held constant
what is monetary neutrality
changes in money supply are assumed to have no effect in the longrun but in the short run do have an effect
3 reasons why the AD curve is downward sloping
the wealth effect
the interest rate effect
the exchange rate effect
what does the wealth effect cause an increase in
consumption
what is the wealth effect
when prices go down, but your income doesnt and you feel more wealthy encouraging you to spend more
what does the interest rate effect cause an increase in
investment
what is the interest rate effect
prices fall and so househoods try to reduce their holding of money by lending it out, boosting savings and investment
what does exchange rate effect cause an increasein
net exports
what is the exchange rate effect
as the value of your currency falls, other countries want to switch to using your products as theyre relatively cheaper. The exports in your country increase and inports decrease
3 reasonswhy the AS curve upward sloping in the short run
- sticky wage theory
- sticky price theory
- misperceptions theory
what is the stiicky wage theory
wages are fixed by contracts, increase in prices reduces the real wage paid by the firm
wages change slowly
what is the sticky price theory
firms don’t just adjust prices immediately in repsonse rto any change in the eonomy,
Stable prices keep regular customers
Menu costs, hard to change
what are menu costs
prices that are associated with printed catelogues and menus, changing these would be expensive and can’t be dont every time there is a change in the economy
what is the misperceptions theory
changes in the overall price level can mislead suppliers in the individual markets they operate in
ie. is this a change in my individual market or inflation/deflation in the economy as a whole
example of misperceptions theory
firm may give a raise to its employees because of inflation, their nominal wage has increase butnot their real wage
However, the employees respond as if they are making more money
why is the AS curve vertical in the longrun
In the longrun, the production of goods and services only depends on the factors of production, price level wont change long run output
where is the long run AS placed
natural/potential level of output
what are the factors of production that can change long run supply
labour
capital
natural resources
technology
what causes shifts in the AD curve1
components of GDP
eg change in government spending, changes in investment, consumption or net exports
changes in supply of money
when supply of money is increased, does AD shift right or left
right
what causes a shift in the long run AS curve
anything that changes potential output (factors of production)
what causes shifts in the AS short run curve
factors of production eg shifts in labour due to immigration/emigration, change in technological knowledge, natural resources or capital
expected price level
