Q

What are the 4 components of AD (e.g. the equation)

A

AD = C + I + G + (X-M)
- C = Consumption –> most significant 60% of total
- I = Investment - 3rd most significant - fluctuates on economy performance
- G = Government Expenditure - Significance increases during downturns/ recessions e.g. 2008 or COVID-19 - 2nd Significant
- X-M = Exports - Imports

Q

Why is the AD curve downwards facing?

A
  • The Real Balance effect –> when Price Level ↑, Purchasing power ↓, leading to a decrease in D for R. Output
  • International Trade Effect –> Price Level ↑, International Competitiveness ↓, D. Exports ↓, D. Imports ↑–>Contraction in AD
  • Interest Rate effect –> ↑Price level –> ↑D for Money –> Interest rates ↑, ↓Consumption and Investment –> Contraction in AD

Q

What Causes a Movement Along AD Curve Vs. Shift in AD Curve?

A

Movement Along = △Price Level

Shift = When one of C+I+G+(X-M) Changes
AD↑ = Curve shifts Right / Outwards
AD↓= Curve Shifts Left / Inwards

Q

How do you work out the Average Propensity to Consume and Average Propensity to Save?

A

APC = Consumption / Disposable Income x 100
–> Proportional of Dispo. Income spent on Consumption
APS = Savings / Disposable Income x 100
–> Proportion of Dispo. Income spend on Saving

21
Q

How do you calculate Net. Trade?

A

(X-M) –> (Exports - Imports)
–> in UK normally negative

22
Q

List things that Influence Net. Trade?

A
  • R. Income
    –> Income ↑ –> Incentive for Firms to Export ↓
    –> Income ↑ –> D. Imports ↑
    –> Net Exports ↓
  • Exchange Rate
    –>Exchange Rate ↑–> Net Trade ↓ (International Competitiveness ↓)
    –> SR Net Trade ↑ due to inelastic Demand
  • World Economy
    –> eg. COVID-19 global recession –> ↓D. Exports
  • Protectionism
    –> tariffs –> Net Trade ↓
  • Non-Price Factors
    –> Quality / Design
23
Q

How does R. Income effect Net Trade?

A

Income ↑ –> Incentive for Firms to Export ↓
Income ↑ –> D. Imports ↑
Net Exports ↓

24
Q

How does Exchange rate effect Net Trade?

A

Exchange Rate ↑–> Net Trade ↓ (International Competitiveness ↓)
–> SR Net Trade ↑ due to inelastic Demand

25
Q

How does the World Economy impact Net Trade?

A

Exports dependent on world growth rates
–> eg. COVID-19 global recession –> ↓D. Exports

26
Q

How does protectionism influence Net Trade?

A

high tariffs (on imports to countries) means exporting is harder / more expensive
–> Net Trade ↓

27
Q

List some Non-Price factors that could influence Net Trade?

A
  • Quality / Design
  • Transport Costs
  • Reliability
