Macro Theory (12) Flashcards
What are the 4 sectors of the circular flow of income
Households, Businesses, Government, External sector
What does the circular flow of income demonstrate
The circular flow model demonstrates how money moves from producers to households and back again in an endless loop.
What do households receive from firms in a circular flow income
Wages, Dividends
What do firms receive from households
Purchases of goods and services
What does the government give and receive in the circular flow of income
The government receives taxes and gives social transfers to house holds and government spending to firms
What does the external sector give and receive
The external sector is different country’s and they give us exports and we give them imports
Why is Y=O=E equal
National income (Y) equals national output (O) and national expenditure (E) as a change in Y changes national expenditure and a change in O will change national income
Why is Y=O=E equal
First of all This is the value of consumer goods and services demanded in a particular period of time. Consumer spending is a function of income. This means that as income changes then so does consumer spending.
What is Y
National Income - The income paid by firms to households
What is O
National output - the output of firms (value of what they produce)
What is E
The National expenditure - Spending by households on the goods and service produced by firms
What is an injection
Income / money introduced into the economy
What are the 3 injections in the economy
Exports, Investment and Government spending
What are withdrawals
Money leaving / leaking out the economy
What are the 3 withdrawals in the economy
Imports, Taxation and Savings
How do injections affect the equilibrium for income
Changes In injections and withdrawals can affect the equilibrium level of income as an increase In injections cause the economy to grow as more money circulating in the economy increases income, decreases unemployment and consumption increase which increases the equilibrium level of income.
How do Withdrawals affect the equilibrium for income
Withdrawals will lower the equilibrium level of income as withdrawals lower GDP this means lower incomes as there is less money to spend.
What is the multiplier effect
The multiplier effect is a process by which an injection into the circular flow of income creates a change in size of national income that’s bigger than the initial injection.
What are the units of AD
Consumption, Investment, Government spending and exports - imports
AD = C + I + G + (X-M)
What is Aggregate demand
Aggregate demand is the sum of all expenditure in the economy over a period of time. (GDP)
What causes a movement along the AD curve
A change in price level
What causes a shift in the AD curve
a shift in the curve will be be because of a change in other factors except from price changes, these factors being the AD components.
Explain the consumption component
Consumption is spending by households on goods & services. Consumer spending is biggest single component of aggregate demand in the UK and is around 60% of GDP in the UK
What are the factors of consumption
Level of and changes in employment
General state of consumer confidence, An increase in consumer confidence determines the willingness of consumers to spend.
Interest rates – Interest rates cause a change in consumption as Higher interest rates make saving more of an incentive as they gain more and they are less likely to borrow as it is more expensive.
Taxation Levels – Tax increases decrease consumption as consumer have less disposable income, A reduction in tax will increase consumption.
Consumer expectations - Consumption could increase if there is an expectation of growth in income or household income.
