Macroeconomics concerns the study of the ‘whole’ economy – eg UK, Europe
The flow of money in an economy – “The Circular Flow of Income”
• The simplest macroeconomic model assumes a ‘two-sector closed economy’ in which all income received is passed on
• Households (H) provide the
factors and in return receive income )in the form of wages, rent, interest and profit) which they spend on goods and services produced by firms (F) in the economy
The Four-Sector Open Economy• The model can be
made more realistic by adding government and overseas sectors and by allowing for injections (J) and withdrawals (W).
• This circular flow diagram shows injections and withdrawals from the simple model of the whole economy.
• This is now a four-sector economy
