CH12: The aggregate demand and supply model Flashcards
Definition: Aggregate demand
the total demand of goods and services that consumers are willing and able to purchase in a national economy during a specific time period
What are factors , other than price, which impact aggregate demand?
ie. cause the demand curve to shift to the right/left
Economic conditions in other (neighbouring countries) - ie. increasing or decreasing exports
Expectations about the future - fears for the feature lead to increased savings/reduced investments and less availability of credit
Competitiveness in the export market - if suppliers abroad are making better goods then then domestic goods may become less competitive and demand for them falls
Government policy - eg. changing tax levels o gov spending, changing interest/fx rates
Definition: aggregate supply?
The total supply of goods and services that firms in a national economy plan on selling during a specific time period
What factors, other than price, affect aggregate supply
ie. cause the supply curve to shift to the right/left
- There is a change in factors of production - eg. availability of labour, raw materials
- There are changing costs - rising costs diminish profitability of the products, so suppliers will be more inclined to supply less and the supply curve shifts left
What is supply limited in the long run?
Spare capacity and resources. Once everyone who is willing and able to work in the economy is employed or there is no more capital available for investment (to increase supply), supply will be at MAXIMUM (ie. supplyy will not change even if there is a change in price
Where does the equilibrium point reach graphically?
Usually just below full capacity/max aggregate supply
Definition: National income
The total amount of goods and services produced over the course of a year, which is equal to the total amount earned by all people and businesses
Definition: Inflationary gap
Aggregate demand exceeds aggregate supply leading to an increase in prices
Definition: Deflationary gap
Spare resources result in costs (eg. unemployment benefits) and prices being low
definition: GDP
The value of goods and services being produces within a country
Definition: GNP
GDP + net income received by residents from their overseas investments
What are two main drivers of economic growth?
Increasing aggregate demand and
Increasing aggregate supply
What factors drive economic growth (i.e. what are drivers of increasing aggregate demand/supply)
Fisca; policy
Monetary policy
Supply side policy
What does a shift in aggregate SUPPLY curve to the RIGHT do in the long term?
(ie. increase in supply)
Increase in national income
Deflation
low unemployment
and visa versa if the supply curve shifts to the left.
(note. situation of rising prices and rising unemployment sometimes referred to as stagflation)
What is the impact of increased interest rates on aggregate supply?
Increased interest rates make it more likely for people to save and make investments more expensive hence the suppliers/businesses are less likely to invest so aggregate supply drops
