A

AD= C+ I + G + (X - M)
* consumption
* investment
* goverment spending

83
Q

what are the 4 components of aggregate demand?

A

85
Q

what is gross investment?

A

87
Q

what happens to aggregate demand when there are
1. increases in price level
2. decereases in price level

A
  1. contraction in aggregate demand (real GSP decreases)
  2. extension in aggregate demand (real GDP increases)
88
Q

what is the share of each componenet of aggregate demand?

A
  • consumption (60%)
  • investment (14%)
  • goverment spending (25%)
  • exports minus imports (1%)
89
Q

what factors cause shifts in AD?

A
  • income
90
Q

how does a decraese income impact AD?

A
  • disposable icmome decreaes, so cosumers have less to spend, reducing consumption, decreasing AD, shifting curve to left
  • Less disposable income means less spent on firms and businesses, so they will not be able to make as much investment
  • less tax able to be collected by goverments- less to spend (tax revenue)

income tax, corporation tax, VAT

91
Q

what is disposable income?

A

the amount of income left over after paying taxes, availiable to spend

92
Q

what is the multiplier effect?

A

an initial increase in injections (consumption/ investment/goverment spending) lead to a larger increase in AD, leading to a bigger overall effect on the economy

93
Q

describe the multiplier effecct

A
  1. jobs created
  2. spend more on firms
  3. firms have more to invest in capital
  4. employ more workers
  5. goverment get an increase in corporation, income and VAT (tax revenue)
  6. goveremnt re- investing starting, increasing goverment spending
  7. the ycle again
94
Q

what is the downwards multiplier effect?

A
  1. more is saved
  2. less spent on firms
  3. laying off employees
  4. reducing income/ consumption
  5. less goveremnt revnue (VAT, Corporation, income)
95

  • increase in consumption
  • firms make more sales, more profit to invest
  • goveremnt collects more income,

96
Q

what are benfits?

A

payments made from the goveremnt to low income workers or umeployed

97
Q

what component does benefits affect?

A
  • not goverment spending (not acc spending),
  • increase in consumption as those households will eventually spend the benefits
  • overall increase in aggregate demand

however opportunity costs of other projects (decrease in G)

98
Q

what does the intrest rate tell you

A
  • savers: return upon savings
  • borrowers: how much you will have to pay back- cost of borrowing

longer time= more intrest to pay

99
Q

what is the impact of savings upon consumption?

A
  • decreases consumption
  • considered a withdrawal from the economy
  • downward multiplier effect
100
Q

what is the impact of intrest rates?

A
  • more money for savers
  • less money for mortage holders
  • less money for firms who want to invest
101
Q

what are the effects of intrest rates on AD?

A
  • Consumers are encouraged to save more and spend less, less C
  • consumers have to pay a higher mortage and would have less disposable income, less C
  • firms are discouraged to invest, less I
  • AD falls, shift in AD to the left
102
Q

how does consumer confidence affect AD?

A

decrease in consumer cofidence, they save more,decreaing consumption, causind AD to shift to the left

103
Q

how does an increase investor confidence impact AD?

aka high animal spirirts

A
  • more investor confidence
  • more investment
  • shift in AD to the right
104
Q

how does the wealth effect impact AD?

A

as assets value incrreases, wealth increases, so consumers are more confident, more household spending = more consumption

happens when house prices increase

105
Q

A
  • in the US where most people are homeowners the wealth effect takes place
  • in euopean countries half th epeople are saving up to buy and house and are renting, so the increase in house perices actually cancels out the wealth affect to 0%
106
Q

how does a decrease in pension affect AD?

A
  • people will have to save more for future, spending less and reducing cosmption, causing AD to shift left
  • those currently retirred have more to spend,
107
Q

what happens when goverment spending increases?

A
  • increase in goverment spending
  • incresae in consumption from new jobs that have been created
108

SPICED

109
Q

how does the exchange rate affect AD?

appreciation

A

116
Q

describe the keynesian LRAS curve

A
  1. at the start nothing is being produced, loads of resources are availible to it is easy to increase output
  2. as more is produced, resources run out, so it is harder to increase output
  3. economy cannot produce anymore because all resources are used up
117
Q

draw the keynesian curve

A

sick back flip

118
Q

what is spare capacity?

when an economy is nearly producing at it’s maximum potential output

120
Q

what is the neoclassical long run aggregate supply model?

A
  • always at full employment
  • in the long run always time to have fully use up all it’s resources
121
Q

neoclassical curve

A

similar to PPF

122
Q

what causes the shifts in the two types of Agreggate Supply?

A
  • LRAS: change in quanity of factors of productivity or productivity
  • SRAS: changes in cost

for suppliers

123

Q

Model an economies short run equilibrium

A
129
Q

Model an economies long run equilibrium (Keynesian)

A
130
Q

Model an economies long run equilibrium with the neoclassical model

A
131
Q

What would the effect of a decrease in incomes have on an economies equilibrium?

A
132
Q

what evaluation can be used with keynesian curves?

A

However, the effect is dependant on where along the LRAS the econpmy is. If our initial equilibrium is at spare capacity (Y1,PL1), a decraese in AD from AD1 to AD2 will not affect the price level, only the real GDP will decrease

Q

draw the simple circlular flow model

A
  • assumed that all factors of production are owned by households
  • factors of income: rent & wages
140
Q

why does national output=national expenditure=national income?

A
  1. the spending from households come from the income that they earn
  2. and expendiyure = ouput as households spend on the output of goods and services
141
Q

what is the circular flow equation?

A

national income= national expenditure= national output

142

  • using real GDP
144
Q

what are the withdrawals/leakages in the circular flow ?

A

things that stop the circulat flow of income (households spending all their income on firms)
* savings
* imports
* taxes

SIT

145
Q

what is a leakage?

A

when money leaks out of the circular flow

146
Q

what are savings within the circulr flow of income?

A

disposable income that is not spent by households (leakage)

147
Q

what are imports in the circulat flow of income?

spending on foreign goods and services

148
Q

what are taxes within the circular flow of income?

A

money paid to the goverment by consumers, firms, workers (leakages)

149
Q

what is an injection?

A

when money is injected into the circular flow

150
Q

what are the types of injections in the circular flow of income?

A
  • goverment spending
  • investment
  • export

GIX

151
Q

What is goverment spending within the circulr flow of income?

A

when the goverment injects money into the economy by spending on schools, teachers, hospitals, doctors….

152
Q

what are exports iwthin the icrcular flow of income?

A

when firms export goods abroad, we recive money to money is injected into the economy

153
Q

what is investment within the circular flow of income?

A

banks use our savings to invest into our firms, injecting money into the circular flow

154
Q

draw the more complex circular flow of income model.

A
155
Q

how do changes in injections and withdrawals affect the economy?

A
  • leakages < injections, money coming into economy, GDP increasing
  • leakages > injections money leaving the economy, GDP decreasing
  • leakages= injections, same amount of money in economy, GDP stays the same
156
Q

what is another formula for real GDP?

A

GIX- SIT

157
Q
A
158
Q

What is the calculation for the multiplier ratio?

A
159
Q

what does the multipler ratio tell us?

A

how much GDP will increase following an initial injection into the economy

160
Q

what does marginal propensity to consume mean?

A

how much consumers are willing to spend if given an additional £1
* if homeless man given £1 and spends 80p, them MPC is 0.8
* only consu,ption within our economy

the lower MPC means less likley to spend, more likley to save

161
Q

what is the muliplier effect?

A

initial injections promote further rounds of spending, causing aggregate demand to increase by more thna the initial injection

162
Q

what is marginal propensity to withdraw?

A

how much consumers are likley to save if given £1
* MPC+MPW=1

163
Q

What are the four ways of calculating the muliplier ratio?

A
164
Q

What is the calculation for the multiplier ratio?

A
165
Q

what is marginal propensity to withdraw

A
  • MPW=MPS+MPm(imports)+MPT
  • Proportion of additional £1 spent on withdrawals(savings, imports,taxes)
166
Q

Uk exports became cheaper, explain the multipler effect?

A
  1. demand for exports increases (injections)
  2. exports are component of AD, AD increases
  3. increase in number of people employed to export
  4. workers will spend, increasing consumption
  5. increasing AD
  6. firms with increased revneu from consumption may wish to expand and increase investment
  7. increasing AD
  8. this may emply more jobs, consumption…………….repeat
167
Q

how could the multipler effect be made larger?

A
  • if MPC was larger
  • initial injection is larger
168
Q

what is the difference between RPI and CPI?

A
  • RPI includes mortgage repayments (unlike CPI)
169
Q

what are the two types of inflation?

A
  • demand pull
  • cost push
170
Q

What is demand pull inflation?

A

When AD increases, causing the price level to rise

171
Q

what is cost push inflation?

A

when the costs of production increase –> SRAS shifts to the left

only occurs with SRAS (costs of production)

172
Q

what is hyper inflation?

A

when demand reaches above 50%

173
Q

what is a deflationary spiral?

A
  1. deflation occurs first, price levels decrease
  2. consumers delay their purchases and instead save- in hope for prices to drop even lower
  3. lack of consu,ption causes AD to shift to the left
  4. after repeated cycles of this, real GPD decreases and unemplyment increases
174
Q

what are the causes of deflation?

A
  1. increase in AS
  2. decrease in AD

sustained decrease in general price level

175
Q

how do inflation and deflation affect the value of money?

A
  • inflation: decraeses the value of money (can buy less goods with £1)
  • deflation: increases the value of the money (can buy more goods with £1)
176
Q

what is nominal and real income?

A

A

(new- original/original) 100

178
Q

what are the 3 stages to calculating the UKs price level?

A
  1. Office of national statstics interviews 7000 households to find the 650 most common goods and services
  2. price survey is conducted to find the average price level
  3. a weighted price level of all the prices is calculated in order to find the price level
179
Q

how do you calculate weighted average?

A

average price × % of total spending

180
Q

what is the formula for consumer price index?

A
181
Q

what is a price wage spiral?

A
  1. due to inflation prices rise
  2. cost of living rises
  3. workers demand higher wages
  4. increasing cost of production for firms–>SRAS shifts to the left
  5. increase in price level

eventually can lead to hyperinflation

182
Q

what are the benefits of inflation?

A
  • no risk of deflationary spiral
  • reduces the real value of debt—> improves inequality (better for the poor)
183
Q

what are the cons of inflation?

A
  • risk of price wage spiral —> hyperinflation
  • reduces the real value of savings
