4. The macroeconomy Flashcards
What is meant by the term national income?
National income measures the monetary value of the flow of output of goods and services produced in an economy, over a given time period
Why are national income statistics so useful for a government?
Only need 2
- Provides a report card of economic growth to governments which allows them to evaluate their economic performance
- Allows governments to see if their policies used to achieve their economic growth goals are succeeding
- Allows governments to forecast expected demand and growth going forward
- National income statistics can be a very important indicator of evaluating living standards
What are the three different measures of national income / economic growth?
- Gross domestic product (GDP)
- Gross national income (GNI)
- Net national income (NNI)
How do we measure GDP?
There are 3 different ways:
- The income method
- The output method
- The expenditure method
The circular flow of income tells us that income = output = expenditure
Meaning all three of these measures of GDP give us the same value
What is the definition of GDP?
The total value of goods and services produced in the economy over a given time period, (normally a year)
What is the benefit of using GDP to measure national income?
It doesn’t just give us a measure of economic growth, but it also gives us a measure of living standards
–> One method of GDP measures income
–> If GDP goes up, then incomes go up, which leads to a higher standard of living
What are the key issues of using GDP as a measure of growth?
- Risk of double counting, (especially with the output method)
This means that we include the value of output in the primary sector, and then we include the value again when that primary commodity has been manufactured into something in the secondary sector - GDP doesn’t take into account informal economic activity, such as illegal or black market activity. However, this also means it doesn’t include informal activities like DIY work. This massively disadvantages LEDCs as they have a more prominent informal economy
One of the main issues of using GDP as a measure of growth is the risk of double counting. How could this be combated?
GDP is the total value of goods and services produced in the economy over a year
If double counting means we are using the value of the commodity in the primary sector and the value of the commodity when it has been manufactured into something in the secondary sector. Then we can change our definition so that we measure the value of final goods, not just goods
This means we won’t measure the value of commodity goods in the primary sector, but rather measure the value of them when they get manufactured into something in the secondary sector
What are some key issues of using GDP as a measure of living standards?
- GDP just looks at the value of output, not the quality. Meaning it doesn’t look at the negative externalities of production. Such as the cost of air pollution. If these externalities were included, then living standards would be lower than what GDP suggests, indicating the measure is inaccurate
- GDP doesn’t take into account other quality of life aspects, such as education and healthcare. Meaning it is a less reliable measure of living standards. This suggests that something like the human development index, (HDI), is a far better measure of living standards
What is GDP per capita?
*CHECK WITH TEACHER TO MAKE SURE THIS IS A GOOD ENOUGH DEFINITION
GDP figure divided by the population, in order to see the average income of individuals in an economy
What is the formula for GDP per capita?
GDP / Population
What is one issue with using GDP per capita to measure the standard of living?
(Same issues as using normal GDP) +
Remittance payments - This is when workers or firms located in one country, go and work in other countries to earn higher incomes. But these firms and businesses then send any income earned back to the home country
GDP per capita does not take into account any factor incomes earned abroad –> However, it is clear that as this money is sent back home, it is being used to improve living standards
–> Lots of money sent back goes to friends and family
What is meant by nominal GDP?
GDP at current prices, not factoring in inflation
What is meant by real GDP?
Real GDP is when the value of all goods and services in the economy are adjusted for inflation
How do we convert a nominal figure into a real figure?
100 x Nominal GDP / Real GDP
What is the definition of GNI?
GNI is the total income generated by a countries factors of production, regardless of where these factors of production are located
What is the formula for GNI?
GNI = GDP + Net factor incomes
There is one additional measure of economic growth used which factors in environmental cost. What is this called?
Green GDP
How do we work out green GDP?
Green GDP = GDP - Environmental costs
What is one issue with using green GDP?
It is difficult to put a monetery value on environmental costs, which means it may require a normative view to do so
This will include human bias
What is the circular flow of income?
Macroeconomic model, which tells us the leakages and injections of an economy, as well as showing us how to measure economic growth
What does the circular flow of income explain?
- Households provide their factors of production to firms
- Firms then combine these factors of production to produce goods and services
- Households then receive factor incomes
- Households then spend these factor incomes on other goods and services made by firms
Draw the circular flow of income.
What is a closed economy?
An economy that doesn’t engage in trade or other financial exchanges with other countries
What is an open economy?
An economy which trades goods and services with other economies
What are the 3 injections?
- Investment
- Government Spending
- Exports
What are the 3 leakages?
- Savings
- Taxation
- Imports
The circular flow of income suggests three ways to measure GDP. What are they?
- Income
- Output
- Expenditure
What are 2 problems regarding the circular flow of income?
- The model assumes that factor incomes generated by households will be spent on goods and services produced by firms, but some will save their income
- The circular flow of income is extremely oversimplified. This is evident by the fact it ignores two main economic agents, the government and the international sector
What is macroeconomic equilibrium?
When leakages and injections are equal to eachother
What is macroeconomic disequilibrium?
When leakages and injections are not equal to eachother
What is aggregate demand?
The total amount of effective demand in the economy
What is the equation for aggregate demand?
AD = C + I + G + (X-M)
What does C mean in the aggregate demand equation?
Consumption
What does I mean in the aggregate demand equation?
Investment
What does G mean in the aggregate demand equation?
Government spending
What does X-M mean in the aggregate demand equation?
Exports - Imports
(Net exports)
What is meant by consumption?
The total spending by households on goods and services in the domestic economy
What is meant by the term investment?
The spending by firms on capital goods to improve their productive capacity
What is meant by the term government spending?
When the government spend money to influence the level of economic activity, in other the short-run and the long-run
What is meant by the term net exports?
The total value of a countries exports take away the total value of a countries imports
What are the determinants of aggregate demand?
C
I
G
(X-M)
What causes a shif in the aggregate demand curve?
If C, I, G or X-M change, then AD will also change, as the equation is AD = C+I+G+(X-M)
Meaning that if one of the determinants of AD increases, then the AD curve shifts outwards
If one of the determinants of AD decreases, then the AD curve shifts inwards
What are some factors that could influence consumption in the economy?
- Level of real disposable income
- Interest rates
- Consumer confidence
- Asset prices
What is meant by the term marginal propensity to consume?
Marginal propensity to consume refers to the consumer’s willingness to spend any additional income earned on consumption
How does the level of real disposable income affect consumption and therefore aggregate demand?
–> If people have more real disposable income, then their marginal propensity to consume will be higher
–> If people have less real disposable income, then their marginal propensity to consume will be higher
What factors might affect the level of real disposable income?
The main factor is income tax
Income tax rates may go down, which would cause real disposable income to rise, (and vise versa)
Or changes in the tax-free allowance, (refers to how much income you have to make before paying income tax)
How do interest rates affect the level of consumption in an economy?
- If interest rates are high, then there is more incentive to save, as the reward for spending is greater
- If interest rates are high, then it also means that the cost of borrowing is higher, which means that people will be less likely to purchase, ‘big ticket purchases’
However, if interest rates are low, then it means that there is less incentive to save, so people consume more. And the cost of borrowing is lower, meaning people are more likely to spend large amounts of money on ‘big ticket purchases’
What is a big ticket-purchase?
A big-ticket purchase, refers to when consumers purchase something special, that they may not always be able to afford
To make these purchases they may have to borrow money
(Ex: Cars, houses and computers)
What are the two main factors that affect consumer confidence?
- Job prospects
- Unemployment rate
How does consumer confidence affect the level of consumption in the economy?
If consumer confidence is high, then people’s marginal propensity to consume is high, as they have good job prospects and the unemployment rate is low
If consumer confidence is low, then people’s marginal propensity to consume is low, as they have bad job prospects and the unemployment rate is high –> Meaning they may be worried they will lose their job, meaning they are more likely to save
How does asset price affect consumption in the economy?
If consumer’s assets are worth more money, then they feel richer, meaning that their marginal propensity to consume will increase
If consumer’s assets have gone down in value, then they feel poorer, meaning that their marginal propensity to consume will decrease
What factors may affect the level of investment in an economy?
- Interest rates
- Business confidence
- Corporation tax
How do interest rates impact the level of investment in an economy?
If interest rates are lower, then the cost of borrowing is cheaper, meaning it is easier for firms to finance the purchasing/leasing of capital goods
If interest rates are higher, then the cost of borrowing is more expensive, meaning it is harder for firms to finance the purchasing/leasing of capital goods
What are the two main factors that affect business confidence?
- Expected profit
- Expected demand
How does business confidence impact the level of investment in an economy?
If firms expect profit and high demand in the near future, then they are likely to be more confident, meaning they will be more willing to invest in capital goods - Marginal propensity to invest increases
If firms don’t expect high levels of profit or demand in the near future, then they are likely to be less confident, meaning they will be less likely to invest in capital goods - Marginal propensity to invest decreases
* As they are expecting low demand, they also don’t need to invest as they don’t need to increase their supply
A key term to use when deciding the impact of corporation tax on investment is retained profit. What is the definition of retained profit?
Retained profit means the profit a business has left over, after paying corporation tax
How does corporation tax impact the level of investment in an economy?
If corporation tax is high, then a business will have less retained profit, which means they will have a lower marginal propensity to invest
* This is because retained profit is one-way businesses finance the purchasing/leasing of capital goods
If corporation tax is low, then a business will have more retained profit, meaning that they will have a greater marginal propensity to invest
What are 3 factors that will impact the level of government spending in an economy?
- Current spending
- Capital spending
- Welfare Spending
How do all 3 of these factors impact government spending?
Current spending, capital spending and welfare spending, are all types of government spending
Meaning that if any of these increase, then so does government spending
What is current spending?
Spending on the maintenance of public services and the payment of public sector wages
What is capital spending?
The money spent by the government on infrastructure projects
What is welfare spending?
The money spent by the government on benefits and pensions
What factors affect net exports?
- Real disposable income earned abroad
- Strong and weak exchange rates
- Protectionism at home and abroad
How do real disposable incomes earned abroad affect net exports?
If there is a boom abroad, and people abroad become richer, then their marginal propensity to import will increase, which means the demand for our countries/economies exports is likely to increase
(Assuming ceteris paribus)
If the levels of real disposable incomes earned abroad decrease, especially in the countries of our major trading partners –> Then the marginal propensity for them to import goods will increase. This will reduce the amount of income revenue generated by our economy, causing net exports to decrease
