2.1 Measuring economic activity Flashcards
How man sectors are there in a closed and simple economy
Household and firms
What does it mean if it is a simple economy
no government intervention
What does it mean if it is a closed economy
no foreign sector
no exports and no imports
Four factors of production
labour, capital, land and enterprise
What is the output flow
households give factors of production to the firms and firms use them to produce the output of good and services
Income flow
Land - rent
Labour - wages
Capital - Interest
Enterprise - Profit
Expenditure flow
household have expenditure on goods and services
What do you assume in a simple and closed economy
households spend all income they earn
no foreign markets
no savings and no investment
What are leakages
Savings
Import expenditure
Taxes
SIT
What are injections
Government spending
Investment
export expenditure
GIE
what do injections add to
the expenditure flow
what do leakages add to
the income flow
what are in a complex and open economy
Financial sector - savings and investment
government sector - taxes and government expenditure
Foreign sector - exports and imports
What does it mean if the sum of all leakages > sum of all injections
Savings + taxes + import expenditure > investment + government spending + exports
Circular flow of income will decrease
What does it mean if the sum of all leakages < sum of all injections
Imports, savings and taxes < exports, government spending and investment
The circular flow of income will increase
What should happen in an equal economy in theory
the output flow, income flow and expenditure flow should equal each other
How is national income measured
GDP = gross domestic product
Three different methods
Different methods of measuring GDP
The output method
The income method
The expenditure method
What is the output method
sum of all the value added all the firms in the economy
deduct the cost of inputs
defines GDP as the ‘total monetary value of all the final goods and services produced within an economy in a year
national output
What are the different production sectors int he economy
Agriculture and mining (primary sector)
Manufacturing (secondary sector)
Services (tertiary sector)
What is the income method
measures the value of all the incomes earned in the economy
GDP = wages + interest + rent + profit = national income
What is the expenditure method
Measures the value of all the spending on goods and services in the economy
Calculates by summing up the different factors
Consumption + investment + Government spending + foreign exports minus imports
C + I + G + (X - M) = national expenditure
