Macroeconomics Year 1 Flashcards
Circular flow of income
Way in which income, money, goods and services flow in an economy
National income
All the incomes that flow to households over a period of time
National output
Value of all the output (goods and services) produced in an economy over a period of time
National expenditure
All the spending by households, firms and government over a period of time
Injections
Routes for money to enter the circular flow of income including through investment, government expenditure and exports
Leakages
Routes for money to leave the circular flow of income including through savings, taxation and imports
Aggregate demand
The ability and willingness of all economic agents to spend in the economy
Consumption
Spending by households on goods and services
Investment
Spending by firms on goods and services to be used in future production
Government expenditure
Spending by the government on goods and services, such as the NHS
Net exports
Exports minus imports
Exports
Foods and services that firms sell overseas
Imports
Goods and services that households and firms buy from overseas firms
Expectation
Views that economic agents have about what will happen to the economy in the future
Aggregate supply
Total supply of all goods and services produced within an economy at a given overall price at a given time
Short run aggregate supply (SRAS)
Goods and services that firms are willing and bale to produce at a given price level in the short run
Long run aggregate supply (LRAS)
The maximum that can be produced with all the factors of production in an economy
Neoclassical approach to aggregate supply
Approach to aggregate supply in which there is a short run curve (where output changes with price level) and a long run curve (where output does not change with price level)
Keynesian approach to aggregate supply
Approach to aggregate supply in which there is no distinction between SRAS and LRAS. One AS curve can show both the short and the long run
Macroeconomic equilibrium
Point at which aggregate demand equals aggregate supply
National income multiplier
Ratio of a change in equilibrium real income to the autonomous change that bought it about
Accelerator
Theory by which the level of investment depends on the rate of change in national income
