Explain the influence of market forces in determining output and prices in the Australian economy.
The
Price mechanism is the process where adjustments in price in a market determine the equilibrium quantiy that consumers will demand and firms will stupply.
If the price is set too low, then there will be excess demand, and a shortage of supply. In this case, the price will move up to reduce demand (according to the law of demand) and to increase supply (according to the law of supply), to the equilibrium point to maximise profit.
Likewise, if the price is set too high, then there will be excess supply, and a shortage of demand, and the price will be reduced to the equilibrium point to maximise profit.

Market failure is the inability of an unregulated market to achieve allocation efficiency in all circumstances. Therefore, because of market failure, government intervention allows for allocation of resources in a way which is best for the economy and society.
There are a number of areas of government intervention. For merit good, which are things important to society such as education and healthcare which would otherwise need to be payed for. For public good which are good which everybody uses such as drains and tragic lights. For externalities which are effects of the actions of producers and consumers which affect other people, such as smoking. Taxes are necessary to pay for these things, therefore there is government intervention.
