However, other argue that a free market creates many problems; notably inequality of distribution. Therefore, because of this it is necessary for the government to intervene in the economic decision making process.

Examples of Market Forces in ActionGood becomes more available
In this diagram above, the good becomes more abundant. This causes the supply curve shifts to the right. This leads to a lower price and increase in quantity.
Therefore, if a good becomes more abundant, the market mechanism makes it cheaper and people buy more. For example, when steel became cheaper in the nineteenth century, it started to be used in many more applications
Fall in supply
In this diagram we have a fall in supply. In this case the opposite happens. Because this good is in shorter supply, the price goes up. This increase in price causes a fall in demand.
For example, as we run out of oil, we should expect the price to go up. This increase in the price of oil will cause demand to fall and people to look for alternatives.
Diagram Showing Increase in Price
In this diagram, we have rising demand (D1 to D2) but also a fall in supply. The effect is to cause a large rise in price. For example, if we run out of oil, supply will fall. However, economic growth means demand continues to rise.
