Q

what does the wealth effect say

A
  • 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

Q

what factors can affect consumption

A

๐Ÿ’ท 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.

๐Ÿ“‰ 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.

๐Ÿ’ณ 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.

๐Ÿ˜ƒ 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.

๐Ÿก 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.

๐Ÿ“‰ 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.

A
  • 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

Q

what would an inward shift of AD do

A

reduce national output at all price levels

18
Q

what does X and M represent in the AD equation

A
  • export revenue coming into the country
  • import expenditure
19
Q

what factors can influence the level of net exports (X - M)

A
  • 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
20
Q

what does SPICED and WIDEC stand for

A
  • strong exchange rate, imports cheap, exports dear
  • weak exchange rate, exports cheap, imports dear
21
Q

what is investment

A

when firms spend money on capital goods to increase their productive capacity

22
Q

what factors can affect investment

A

๐Ÿ“ˆ 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

๐Ÿ’ญ 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

๐Ÿง  3. Keynes and โ€˜Animal Spiritsโ€™
Businessesโ€™ willingness to invest โ†’ driven by confidence and optimism (Keynesโ€™ โ€œanimal spiritsโ€) โ†’ if entrepreneurs feel positive about the economy โ†’ they are more likely to invest, even without clear market signals

๐ŸŒ 4. Demand for Exports
Increase in foreign demand for a countryโ€™s goods โ†’ firms expect higher sales โ†’ encourages investment to expand capacity โ†’ firms invest to take advantage of the growing market

๐Ÿ’ธ 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

๐Ÿ’ณ 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

๐Ÿ› 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

23
Q

what are interest rates

A
  • cost of borrowing
  • reward for saving
24
Q

what is the hurdle

A

the required rate of return firms need for investment projects to go ahead

25
what is business confidence determined by
๐Ÿ“‰ 1. Macroeconomic Stability If inflation, interest rates, and exchange rates are stable โ†’ It becomes easier for firms to plan for the future without sudden cost shocks โ†’ This reduces uncertainty and encourages long-term investment โ†’ So macroeconomic stability raises business confidence. ๐Ÿ›๏ธ 2. Government Policy and Regulation If firms expect supportive fiscal or supply-side policies (e.g. tax cuts, deregulation) โ†’ They are more likely to believe that the economic climate will be favourable for growth โ†’ Reduced red tape or lower corporation tax boosts expected profits โ†’ Leading to higher business confidence and investment. ๐ŸŒ 3. Global Economic Conditions If global demand is rising (e.g. major trading partners are growing) โ†’ Export-oriented businesses will expect higher sales and profits โ†’ This encourages expansion and hiring to meet future demand โ†’ So strong global conditions can raise domestic business confidence. ๐Ÿง‘โ€๐Ÿ’ผ 4. Consumer Confidence and Spending If consumers feel optimistic about their income and jobs, consumption rises โ†’ Firms see increased demand and anticipate higher future revenues โ†’ This encourages them to invest in capacity, innovation, and hiring โ†’ So high consumer confidence directly boosts business confidence.
26
what is retained profit
the profit left after corporation tax has been paid
27
what is corporation tax
a tax on business profits
28
what is the accelerator effect
when there is an increase in rate of real gdp in the economy and that encourages further investment
29
what are savings
the part of disposable income which is not spent on goods and services in the economy
30
how do savings contribute to the increase or decrease in AD
- increased savings will decrease consumption, which is a variable in the AD equation, and vice versa
31
factors which can affect savings
๐Ÿ’ท 1. Real Disposable Income When real disposable income rises โ†’ Households have more income after tax and inflation โ†’ This allows for both higher consumption and increased savings โ†’ So the marginal propensity to save (MPS) may rise, depending on income levels and expectations. ๐Ÿ’ฐ 2. Interest Rates Higher interest rates increase the reward for saving โ†’ The opportunity cost of spending rises, encouraging households to save more โ†’ A higher MPS reduces consumption, shifting AD to the left โ†’ Conversely, low interest rates discourage saving and promote consumption. ๐Ÿ˜Ÿ 3. Consumer Confidence If consumer confidence is low (e.g. due to recession fears or job insecurity) โ†’ Households may choose to increase precautionary savings and cut spending โ†’ This reduces the marginal propensity to consume (MPC), slowing economic growth โ†’ So pessimism in the economy leads to higher savings levels. ๐Ÿฆ 4. Financial Infrastructure and Trust In countries with well-developed, secure financial systems โ†’ People are more likely to save through banks, pensions, and financial products โ†’ In contrast, in developing economies with corruption or instability, trust in banks is low โ†’ This may lead to less formal saving and more current consumption. ๐ŸŽ“ 5. Education and Financial Literacy If individuals are educated about the long-term benefits of saving โ†’ They are more likely to budget, delay gratification, and plan for retirement or emergencies โ†’ This increases the marginal propensity to save in the long term โ†’ Boosting national saving rates and potentially supporting investment. ๐Ÿฆ 6. Tax Incentives (e.g. ISAs) Government schemes like Individual Savings Accounts (ISAs) or pension tax relief โ†’ Allow people to earn interest or returns tax-free โ†’ This increases the net reward for saving and encourages long-term financial planning โ†’ Raising overall household savings and supporting capital markets. ๐Ÿ‘ต 7. Age Structure of the Population Younger individuals are typically in a consumption-heavy life stage (education, housing, family) โ†’ Older individuals are more likely to save for retirement or draw down savings more slowly โ†’ An ageing population may increase national savings (or reduce it if people are withdrawing pensions) โ†’ So the age structure influences both the MPS and national saving trends.
32
evaluation points for things than affect exports
โš–๏ธ 1. Elasticity of Demand for Exports Even if a factor (e.g. weaker exchange rate) makes exports cheaper โ†’ The impact on export value depends on the price elasticity of demand โ†’ If demand for exports is inelastic, a fall in price wonโ€™t boost export revenue much โ†’ So export volumes may rise, but overall revenue gains could be limited. ๐ŸŒ 2. Global Economic Conditions Matter More A country may boost its competitiveness or weaken its currency โ†’ But if trading partners are in a recession, their demand for imports falls โ†’ This weakens export demand regardless of price advantages โ†’ So global context may override domestic improvements. ๐Ÿญ 3. Export Supply Constraints Even if demand for exports rises (e.g. due to a weaker currency or trade deals) โ†’ Domestic firms may lack the capacity or resources to scale up output (due to skills shortages or capital limits) โ†’ This limits how much export volume can actually increase โ†’ So gains may not materialise unless LRAS also expands. ๐Ÿ“‰ 4. Time Lags and J-Curve Effect Following a currency depreciation or trade policy change โ†’ Export volumes may take time to adjust (e.g. firms need to find new customers, contracts are fixed short-term) โ†’ This means that in the short run, exports might not rise โ†’ But in the long run, export values may increase if Marshall-Lerner conditions are met. ๐Ÿงฎ 5. Relative Inflation Rates Even with a weak exchange rate, if domestic inflation is high โ†’ The real price of exports might not actually fall by much โ†’ High costs make exports less competitive in global markets โ†’ So inflation can cancel out expected benefits to exports. ๐Ÿ”ง 6. Degree of Specialisation and Innovation The long-term ability to grow exports relies on non-price factors โ†’ Countries with highly innovative or specialised export sectors (e.g. Germanyโ€™s engineering, South Koreaโ€™s tech) โ†’ Can maintain strong exports regardless of short-term cost fluctuations โ†’ So competitiveness isn't just about prices, but also quality and branding.
33
Explain the J curve
SHORT RUN - After a currency depreciation, the prices of imports rise immediately,imports more expensive. - Export prices in foreign currency terms may not adjust as quickly, causing the value of exports to remain relatively unchanged initially. - As a result, the trade balance worsens because the higher cost of imports outweighs the unchanged value of exports. LONG RUN - Over time, consumers and businesses adjust to the new prices. Import volumes start to decline due to higher costs, and export volumes increase as foreign demand rises for relatively cheaper goods - Eventually, the trade balance improves as the volume effects of increased exports and reduced imports outweigh the initial price effects. The increased competitiveness of the country's goods leads to higher export revenues, and the reduced import demand lowers import expenditures.
34
What is disposable income?
Disposable income is the amount of income a household has left after paying taxes and receiving government transfers. It is used for consumption or savings.
35
What is the difference between gross investment and net investment?
Gross investment is the total amount spent on capital goods, including replacement and new investment. Net investment is gross investment minus depreciation (the reduction in value of capital goods over time). Net investment represents the actual increase in capital stock.
36
What are Keynes' "animal spirits" in the context of investment?
refers to the emotions and instincts that drive business decisions, especially investment. Confidence, optimism, or fear can strongly influence business investment, sometimes regardless of economic fundamentals.
37
What is the net trade balance
the difference between a country's exports (X) and imports (M)
38
What is the distinction between actual and potential growth?
Actual growth refers to the increase in real national output (GDP) over time, measured by the actual output produced in the economy. Potential growth refers to the increase in the economyโ€™s capacity to produce goods and services over time, measured by the economy's long-run trend growth.
39
What is the distinction between actual growth rates and long-term trends in growth rates?
Actual Growth Rates: Definition: The actual percentage increase in a country's real GDP (Gross Domestic Product) over a specific period, typically a year. Long-Term Trends in Growth Rates: Definition: The average sustainable rate of economic growth over a longer period, reflecting the underlying potential of an economy.
40
problems with using the dollar to compare GDP
๐Ÿ’ฑ 1. Exchange Rate Distortions GDP figures must be converted into USD using exchange rates โ†’ But exchange rates can fluctuate daily due to speculation, interest rate changes, or political instability โ†’ This may distort the true value of output when converted to dollars โ†’ Making comparisons inaccurate, especially in the short run. ๐Ÿงบ 2. Cost of Living Differences A dollar can buy different quantities of goods in different countries โ†’ For example, $1 buys more in India than in the US due to lower local prices โ†’ So nominal GDP in USD may underestimate real living standards in low-cost economies โ†’ Leading to misleading conclusions about development or welfare. ๐Ÿ“‰ 3. Impact of Currency Depreciation If a countryโ€™s currency depreciates (e.g. due to a crisis), its GDP in dollars will fall โ†’ Even if domestic output and welfare stay the same โ†’ This gives a false impression of economic decline โ†’ So dollar comparisons can confuse exchange rate changes with real output changes. ๐Ÿ“Š 4. Does Not Reflect Informal or Non-Market Output In many developing economies, a large share of GDP comes from informal or subsistence activity โ†’ These are hard to measure accurately in national statistics, especially when valuing in USD โ†’ The use of the dollar may therefore exclude significant portions of real economic activity โ†’ Undermining fair international comparisons.
41
things affecting govt expenditure
๐Ÿ“‰ 1.1 Economic Recession During a recession โ†’ government expenditure often increases โ†’ to stimulate demand and support the economy โ†’ higher spending on welfare, unemployment benefits, and public infrastructure ๐Ÿ“ˆ 1.2 Economic Expansion In periods of economic growth โ†’ government expenditure may decrease โ†’ due to reduced need for stimulus measures โ†’ more revenue from taxes, reducing reliance on public spending ๐Ÿ’ธ 1.3 Inflationary Pressures When inflation rises โ†’ government may increase spending on subsidies or price controls โ†’ to protect consumers from rising costs โ†’ maintaining economic stability and consumer purchasing power If the government aims to reduce unemployment โ†’ they may increase public sector investment โ†’ to create jobs and stimulate demand โ†’ boosting economic activity and reducing unemployment rates ๐Ÿ’ฐ 2.2 Budget Deficit or Surplus If the government is running a deficit โ†’ it may increase expenditure on public goods โ†’ to stimulate demand and promote growth โ†’ or it may reduce spending in case of a surplus to control inflation ๐Ÿ’ณ 2.3 Taxation Levels When the government raises taxes โ†’ it may reduce disposable income โ†’ leading to lower private consumption โ†’ the government may counter this with higher public sector spending to support demand
42
how interest rates affect asset prices
๐Ÿ”น 1. Interest Rates โ†‘ โ†’ Asset Prices โ†“ ๐Ÿ“‰ Central bank raises interest rates โ†’ Borrowing becomes more expensive and saving becomes more attractive โ†’ Demand for assets like houses or shares falls as investors shift to interest-bearing assets โ†’ ๐Ÿ ๐Ÿ“Š Asset prices fall due to lower demand and higher discounting of future returns ๐Ÿ”น 2. Interest Rates โ†“ โ†’ Asset Prices โ†‘ ๐Ÿ“ˆ Interest rates are cut by the central bank โ†’ Lower cost of borrowing encourages investment and mortgage lending โ†’ Demand for assets like property and equities rises โ†’ ๐Ÿ˜๏ธ๐Ÿ“ˆ Asset prices increase due to higher demand and lower discount rates ๐Ÿ”น 3. Stock Market Valuations Affected via Discounting Future company profits are discounted at prevailing interest rates โ†’ When interest rates fall, the present value of future earnings rises โ†’ This makes shares more valuable, even if profits havenโ€™t changed โ†’ ๐Ÿ“Š Stock prices go up due to revaluation of expected returns ๐Ÿ”น 4. Wealth Effect from Asset Price Changes Higher asset prices increase household wealth โ†’ Wealthier households may increase consumption (positive wealth effect) โ†’ This can further boost demand for assets, creating a feedback loop โ†’ ๐Ÿ’ท Economy experiences a rise in confidence and spending, especially in housing markets
