Week 1 Flashcards
why is the PPF bow shaped?
illustrates the concept of increasing marginal opportunity costs.
-Increasing marginal opportunity costs demonstrate an important economic concept:
The more resources already devoted to an activity, the smaller the payoff to devoting additional resources to that activity
how can economic growth lead to shift in the PPF?
the resources available to an economy may increase.
For example, both the labour force and the capital stock—the amount of physical capital available in the country—may increase. The increase in the available labour force and the capital stock shifts the production possibility frontier outwards for the Australian economy and makes it possible to produce both more wheat and more wool.
how do outward shifts of PPF represent economic growth?
because they allow the economy to increase the production of goods and services, which ultimately raises the standard of living
as more economic resources become available and technological change occurs, the economy can move from point A to point B, producing more wool and more wheat.
show how technological change in one industry can lead to shift in ppf
shows the results of technological advance in the wheat industry that increases the quantity of wheat that workers can produce per year, while leaving the maximum quantity of wool that can be produced unchanged. Shifts in the production possibility frontier represent economic growth.
what is expansion
The period of a business cycle during which total production and total employment are increasing above trend growth
what is contraction
The period of a business cycle during which total production and total employment are falling below the trend rate of economic growth
what is recession
two consecutive quarters of negative economic growth as measured by a country’s gross domestic product (GDP)
inflation rate
The percentage increase in the general price level in the economy
what is GDP
market value of all final goods and services produced in a country over a particular period of time
GDP = C + I + G + Xn
what is an intermediate good or service
A good or service that is an input into another good or service.
describe the value added method
§An alternative way to calculate GDP is the value-added method.
Value added: The market value a firm adds to a product.
§GDP can be calculated by adding up the value added by every firm involved in the production process of goods and services.
what is net gdp
§Calculated by measuring GDP and subtracting the value of depreciation on capital equipment.
what is GNI
Australia’s GDP plus income generated overseas by Australian residents and firms, minus the income generated in Australia by non-residents and foreign firms.
what 3 alternative methods are used by ABS to measure GDP
- Production method
- Expenditure method
- Income Method
what is the production method
The sum of the value of all goods and services produced by industries in the economy in a year minus the cost of goods and services used in the production process, leaving the value added by the industries.
what is the expenditure method
The sum of the total expenditure on goods and services by households, investors, government and net exports (the value of exports minus the value of imports
what is the income method
The sum of the income generated in the production of goods and services, which includes profits, wages and other employee payments, income from rent and interest earned
features of circular flow diagram
-The circular-flow diagram shows the flow of spending and money in the economy.
-It illustrates the equality between GDP measured using the income and expenditure methods.
the income generated in the production of goods and services is equal to the value of expenditure on these goods and services.
are transfer payments included in GDP
no
describe the circular flow diagram
The circular-flow diagram illustrates the flow of spending and money in the economy. Firms sell goods and services to three groups: domestic households, foreign firms and households, and the government. To produce goods and services, firms use factors of production: labour, capital, natural resources and entrepreneurship. Households supply the factors of production to firms in exchange for income in the form of wages, interest, profit and rent. Firms make payments of wages and interest to households in exchange for hiring workers and other factors of production.
The sum of wages, interest, rent and profit is total income in the economy. We can measure GDP as the total income received by households. The diagram also shows that households use their income to purchase goods and services, pay taxes and save. Firms and the government borrow the funds that flow from households into the financial system. We can measure GDP either by calculating the total value of expenditures on final goods and services or by calculating the value of total income.
§ABS divides GDP into four major categories of expenditures.
these include
- Consumption
- Invesment
- Government expenditure
- Net exports (value of exports - value of imports)
Y = C + I + G + NX
shortcomings of GDP as a measure of total production (it is a good measure but not flawless)
GDP does not include:
Household production: Goods and services people produce for themselves.
–Examples: home cooking, cleaning, childcare, gardening, home maintenance.
The underground economy: Buying and selling of goods and services that is concealed from the government to avoid taxes or regulations or because the goods and services are illegal.
how the underground economy is hurting developing countries
Trade taking place in the underground economy reduces tax receipts for the government, thereby reducing the services they are able to provide.
shortcomings of GDP as a measure of wellbeing i.e. economic development
- The distribution of GDP is not captured in GDP measures.
- The value of leisure is not included in GDP.
- The level, quality of, and access to health care and education is not measured in GDP.
- GDP is not adjusted for pollution or other negative effects of production.
- GDP is not adjusted for changes in crime and other social problems.
