Theme 2 - Aggregate demand Flashcards
(42 cards)
what is aggregate demand
the total demand for a countries goods and services at a given price level in a given time
equation for AD
C + I + G + ( X - M)
what does the wealth effect say
- When the value of assets such as property, stocks, or savings rises, individuals perceive an increase in their overall wealth
- People may feel more financially secure and willing to make significant purchases or spend on luxury items.
- Increased consumer spending stimulates demand for goods and services, which can drive economic growth
- and vice versa
when is there a shift in AD
when C,I,G,X, or M changes, nothing to do with price level
what is consumption
the total spending by households on goods and services in the economy
60 percent of ad
what is the MPC
the marginal propensity to consume is the willingness of a household to spend any extra income that they earn
what factors can affect consumption
๐ท 1. Level of Disposable Income
If real disposable income increases (e.g. due to income tax cuts or wage growth) โ
Households have more money available after tax and inflation โ
This increases their marginal propensity to consume (MPC) โ
Boosting consumption and shifting aggregate demand (AD) to the right.
๐ 2. Interest Rates
When interest rates fall, the cost of borrowing decreases and the return on savings declines โ
This encourages households to borrow more and save less โ
Consumption increases, especially on big-ticket items like cars or appliances โ
Causing a rise in AD and potentially stimulating economic growth.
๐ณ 3. Availability of Credit
Even if interest rates are low, if banks restrict lending or if consumers fail credit checks โ
Households cannot access credit to finance consumption โ
This reduces the effectiveness of monetary policy in stimulating spending โ
So consumption remains subdued despite lower rates.
๐ 4. Consumer Confidence
If consumers are optimistic about future income and job security โ
They are more willing to spend rather than save โ
This raises the MPC and leads to greater consumption across the economy โ
Supporting higher AD and short-run economic growth.
๐ก 5. Asset Prices (e.g. Housing and Stocks)
Rising house or stock prices make households feel wealthier (wealth effect) โ
This boosts consumer confidence and encourages more discretionary spending โ
Especially as homeowners may remortgage to unlock equity โ
Causing a rightward shift in AD through increased consumption.
๐ 6. Household Indebtedness
If households hold high levels of debt (e.g. mortgages, credit cards) โ
They may prioritise debt repayment over new spending, especially if interest rates rise โ
This lowers the MPC and depresses consumption โ
While households with low debt levels are more likely to increase spending when income rises.
what can impact consumer confidence
- job prospects, if people believe they are likely to get promoted,their MPC may increase
- level of unemployment in the economy, people will feel more confident and secure in their job, making them spend more
Examples of asset prices
- house prices
- share prices
- bond prices
what are the types of government spending which can take place in the economy
- current spending - the spending on the maintenance of public services and public sector wages
- capital spending - spending on infrastructure projects, like railway lines
- welfare spending - spending on benefits and pensions, eg disability and child support, biggest part of govt spending
debt interest payments - when govt take out money out of the international bank, interest is added on that needs to be paid
how much money goes to debt interest payment
around 50 billion pounds
what is a budget deficit
when govt spending is greater than tax revenue in a fiscal year
what is a budget surplus
where govt spending is less than tax revenue in a fiscal year
what is national debt
the total stock of debt over time, the accumulation of budget deficits
what would cause AD to shift to the right
an increase in CIGXM
what will an outward shift of AD do
will raise national output at all price levels
what would an inward shift of AD do
reduce national output at all price levels
what does X and M represent in the AD equation
- export revenue coming into the country
- import expenditure
what factors can influence the level of net exports (X - M)
- real disposable income earned abroad, if there is a boom in the country abroad, the citizens are getting richer, their MPC to import goods likely to increase, Strong economic growth in the domestic country increases income and spending power, leading to higher demand for imports, the demand for exports likely to increase, shifting AD to the right, and vice versa
- real disposable income earned at home, boom in the UK, the MPC to import likely to rise, import expenditure likely to rise, shifting AD to the left, vice versa
- exchange rates - (SPICED and WIDEC), eg a strong exchange rate, cheap imports, demand for imports will rise and so will expenditure on imports, exports are more expensive, demand will fall, shifting AD left,revenue generated from exports will fall, vice versa
- protectionism from home and abroad, non tariff barriers, sanctions etc, may prevent trade with other countries, may reduce the revenue that can be generated through exports, strong protectionism abroad means X will be lower, shifting AD to the left and vice versa if there is strong protectionism of imports at home
- relative inflation rate at home - if the inflation rate at home is greater than that overseas, exports will be less competitive, demand for exports will decrease, the amount of export revenue will be lower, shifting AD to the left, vice versa
- import expenditure also increase if inflation is high, may be cheaper to buy things abroad as they can be imported
what does SPICED and WIDEC stand for
- strong exchange rate, imports cheap, exports dear
- weak exchange rate, exports cheap, imports dear
what is investment
when firms spend money on capital goods to increase their productive capacity
what factors can affect investment
๐ 1. Rate of Economic Growth
Higher economic growth โ increases business profits and consumer demand โ firms are more likely to invest to meet growing demand โ investment increases as businesses expect future growth
๐ญ 2. Business Expectations and Confidence
Positive business expectations โ firms believe future demand will increase โ businesses invest in new projects, equipment, and infrastructure โ boosts investment levels and economic growth
๐ง 3. Keynes and โAnimal Spiritsโ
Businessesโ willingness to invest โ driven by confidence and optimism (Keynesโ โanimal spiritsโ) โ if entrepreneurs feel positive about the economy โ they are more likely to invest, even without clear market signals
๐ 4. Demand for Exports
Increase in foreign demand for a countryโs goods โ firms expect higher sales โ encourages investment to expand capacity โ firms invest to take advantage of the growing market
๐ธ 5. Interest Rates
Lower interest rates โ cheaper cost of borrowing for firms โ businesses are more willing to take out loans for investment โ increases in investment as firms can finance expansion more easily
๐ณ 6. Access to Credit
Easier access to credit โ businesses can borrow more easily โ facilitates investment in capital, technology, or infrastructure โ investment increases as firms can finance growth opportunities
๐ 7. Influence of Government and Regulations
Government policies (e.g., tax incentives, subsidies, deregulation) โ reduce costs or risks of investment โ firms are more willing to invest in projects โ increases investment levels in the economy
what are interest rates
- cost of borrowing
- reward for saving
what is the hurdle
the required rate of return firms need for investment projects to go ahead
