AS Unit 4: The Macroeconomy Flashcards
National income statistics
National income is a country’s total output. People earn an income from producing output. This is spent on the output. Total output should equal total income and total expenditure
National income statistics measures an economies economic activity in terms of its output, income and expenditure. A government measures output to assess the economies performance. It is doing well if growing at a sustained and sustainable way. Can also be used to compare different countries
Higher output can increase living standards. If growing slowly a government may introduce policies to stimulate the economy
Gross domestic product
Used by economists, governments and international organisations to assess what is produced, earned and spent in an economy
Gross national income
It changes focus from output to income earned by the country’s residents and firms regardless of where it is earned. It adds net property income from abroad. These payments are not receipts of compensation of employees and net taxes less subsidies on products
Compensation of employees is wages earned by workers who are resident in 1 country but work abroad for short periods
Some tax revenue on products may be paid to other countries and international organisations and some production subsidies may be received by others
Governments also measure gross national disposable income which includes income sent home to relatives minus income sent by foreigners working in the country to abroad
Differences in GDP and GNI
Mostly they are similar. Some have a higher GDP than GNI because foreign MNC’s and foreign workers make an important contribution to output. This can be due to foreign investment but can lead to a net outflow of profits and other income
Countries may have a higher GNI than GDP because they receive a net inflow of property income from abroad
Methods of measuring GDP
The output, income and expenditure methods. Should all give the same total because they all measure the circular flow of income in an economy. The value of output is equal to the incomes earned producing it
The output methods
Measures the value of output produced by industries. Avoid counting the same output twice. To avoid double counting, output is measured either by totalling the value of the final goods and services produced or by adding the value added at each production stage. Value added is the difference between the price a firm pays for the goods and services it buys from other firms and the price it sells its product for
The income method
The value of an output produced based on the costs involved in producing that output. The costs include wages, rent, interest and profits. These represent income paid to factors of production. Transfer payments are not included
The expenditure method
GDP is calculated by adding up consumer expenditure, government spending on goods and services, total investment, changes in stocks and the difference between exports and imports. Transfer payments are not included. Add expenditure on exports and deduct expenditure on imports
Market prices and basic prices
GDP and GNI are measured in market prices and basic prices. Market prices are the prices charged to consumers. They include any taxes on products and deduct any subsidies given to producers
Basic prices are the prices which would be charged without government intervention and which equal the income paid to the factors of production for making the output. To get from market prices to basic prices, taxes are deducted and subsidies are added
Gross values and net values
GDP and GNI include gross investment. This includes the output of capital goods that have worn out or become out of date due to advances in technology and capital goods required to expand capacity
Net domestic product and net national income only include net investment. They deduct the value of replacement capital goods. This is depreciation or capital consumption
Net investment shows if a country’s ability to produce goods and services in the future will increase, stay the same or decrease
The circular flow of income
Shows how income, spending and output move around an economy
Open and closed economies
An open economy takes part in international trade. A closed economy does not export or import goods or services.
The impact of injections and leakages
Some income is saved, some is taxed and some is spent on imports. Some expenditure is also additional to the spending that comes from the incomes generated by domestic output. These extra items of spending (injections) are investment, government spending and spending by foreigners on a country’s export
Equilibrium and disequilibrium income
For income to be unchanged, injections of extra spending must equal leakages
If injections are greater than leakages, there will be extra spending in the economy causing income to rise. If leakages exceed injections more spending will leave the circular flow and income will fall.
A rise in investment will cause a rise in GDP. The higher investment results in an increase in production, income and spending
A fall in saving will have the same effect. An increase in saving will mean some products will be unsold so production will fall. Equilibrium income is where investment + government spending + exports = saving + taxation + inmports
Income will move to a higher equilibrium if any injection rises or withdrawal falls. More tax revenue collected from households and firms will reduce the amounts they have available for spending
A rise in saving or imports will also cause GDP to fall
Links between injections and leakages
An increase in investment will raise incomes. As people get richer, they tend to save more. Extra savings can finance more investment. Higher government spending may raise tax revenue by increasing incomes. A greater value of exports will also increase incomes. As incomes rise, more tends to be spent not only on domestically produced products but also on imports
Aggregate demand
Describes the total spending of consumers, firms and the government + foreigners spending on the country’s exports-spending by the country’s consumers, firms and government on imports
Consumer expenditure: consists of spending by households on goods and services
Investment: spending by private sector firms on capital goods
Government spending: on goods and services
Net exports: the difference between the value of exports of goods and services and the value of imports of goods and services
Determinants of the components of AD
Consumer expenditure
Investment
Government spending
Net exports
Consumer expenditure
Spending by households on goods and services to satisfy current wants. The main influence is the level of disposable income. Consumer expenditure may exceed income by drawing on past savings or borrowing (dissaving). Some income can be saved when they rise (disposable income-expenditure). Other factors include the distribution of income, interest rates, availability of credit, expectations and wealth. More equal distribution of income will increase spending since the rich losing income are unlikely to cut back on spending and vice versa. Spending rises when interest rates are low since returns from saving will be reduced, buying on credit is cheaper and hose who have borrowed have more to spending. If it is easier to get loans, spending will rise. When people are optimistic that jobs are secure and incomes will rise, spending will rise as will a rise in wealth
Investment
Private sector spending by firms on capital goods. The amount of this is influenced by changes in consumer demand, interest rates, technology, cost of capital, expectations and government policy. If demand rises, firms will buy more to expand capacity. A fall in interest rates will stimulate a rise in investment since the cost will fall. Firms that borrow to buy capital will dins it cheaper and the opportunity cost of investment may fall. These also raise demand. Advances in technology will rise capitals productivity and more investment. When optimistic that the economy is improving, investment is encouraged. Government can cut corporate tax and provide subsidies
Government spending
Expenditure on providing merit goods and public goods. This is influenced by government policy, tax revenue and demographic changes. If a government wants to raise growth, it will raise spending. Higher revenue will enable more spending. Pressure for a rise in spending may come from a rise in the number of children and/or the elderly
Net exports
Influenced by the country’s GDP and other countries, the price and quality of competitiveness of the products and the exchange rate. When a country’s GDP rises, demand for imports rises. Some may be diverted to the domestic market. When incomes rise abroad, demand for exports will rise which may also have resulted from an improvement in competitiveness. If the exchange rate falls in value, exports will be cheaper and imports will be more expensive. If demand for these is elastic, export revenue will rise, imports expenditure will fall causing net exports to fall
The AD curve
Shows the different quantities of total demand for the economy’s products at different prices. A demand curve for a product assumes that the prices of other products have not changes. More is purchased when price falls partly from people changing from other firms. In the AD curve the prices of most products are changing the the same direction
Why does AD fall when price rises?
The wealth effect: A rise in the price level will reduce the amounts of product wealth can buy. The purchasing power of savings held in bank accounts and other financial assets will fall
The international effect: A rise in the price level will reduce demand for net exports as exports will be less price competitive while imports will become more price competitive
The interest rate effect: A rise in the price level will increase demand for money to pay the higher prices. This increases the interest rate. This results in a fall in consumption and investment
Shifts in the AD curve
A change in price causes movement along the curve. If any non-price influence causes AD to change, the curve will shift. Left = a decrease in AD, right = an increase in AD
A change in any non-price level influence on consumption, investment, government spending and net exports will fist AD
A rise in consumer confidence, cut in income tax, increase in wealth, rise in money supply, rise in population
Rise in business confidence, cut in corporate tax, advances in technology
Desire to stimulate economic activity, desire to win political support
Fall in exchange rate, rise in quality of domestic products, increase in incomes abroad
Aggregate supply
The total planned supply of all the producers in the country. SRAS is the output that will be supplied in a period of time when the prices of factors of production have not has time to adjust to changes in AD and price level. LRAS is the output that will be supplied in the time period when the prices of the factors of production have fully adjusted to changes in AD and the prices level
SRAS
A price rises producers are willing and able to supply more goods and services due to:
The profit effect: As price increases, the prices of factors do not change so the gap between output and input prices widens, increasing profit
The cost effect: It is assumed that input prices remain unchanged but average costs may rise as output increases so to cover this, producer will require higher prices
The misinterpretation effect: Producers may confuse changes in the price level with changes in relative price and that a rise in price they receive means it is more popular so produce more
Shifts in SRAS
Change in price of factors: A rise in wages not matched by an increase in productivity and raw material costs will decreases SRAS, shifting it to the left
Change in taxes: A reduction in corporation or indirect taxes will increase SRAS
Change in productivity/quality: A rise in labour or capital productivity will cause an increase in AS in the short and long run
Change in quantity: In the short run, supply of inputs may be influenced by supply-side shocks, may not have significant impact on productive potential in the long run
LRAS
Shows the relationship between real GDP and changes in price when there has been time for input prices to adjust to changes in AD. Keynesians represent it as perfectly elastic at low output then finally perfectly inelastic. This emphasises the view that in the long run an economy can operate ay any output and not at full capacity. When output is low, firms can attract more resource without raising prices. There is time for input prices to change but due to low AD, they don’t. As output rises, there are input shortages so prices increase. New classical economists have LRAS as a vertical line because they think that in the long run the economy will operate at full capacity. They think a rise in AD may increase putout in the short run by encouraging firms to make use of resources. In the long run, more intensive use of resources will raise production costs. The economy will move to a new SRAS and back to the LRAS curve. Output will return to the initial level but at a higher price.
Shifts in the LRAS
Net immigration will increase the size of the labour force if of working age
Raising retirement age will increase the size of the labour force
More women entering the labour force
If gross investment exceeds depreciation there will be additions to the capital stock
The discovery of new resources can increase a country’s productive potential
Land reclamation
What are the main causes of an increase in the quality of resources?
Improved education and training = rises labour productivity
Advances in technology - reduce costs and increase productive capacity
