* Theory backed up with examples of the simplest to the most complicated models, for example:
* The model of "a closed economy without a government" to one in which government expenditure and revenue affect the level of national income
* The model in which the rate of interest and quantity of money have no effect and the model in which they are variables relevant to the determination of income
