Scarcity in a Free Market
If there is scarcity of a good the supply will be falling. This scarcity causes the price to rise. In a free market this rising price acts as a signal and therefore demand for the good falls. Also the higher price of the good provides incentives for firms to:
- Look for alternative sources of the good e.g. new supplies of oil from antarctic
- Look for alternatives e.g. solar panel cars
Therefore, in a free market there are incentives for the market mechanisms to deal with the issue of scarcity.
However, the market can also have market failure. For example, firms may not think about the future until it is too late. Therefore, when the good becomes really scarce there might not be any alternative that has been developed.
One solution to dealing with scarcity is to implement quotas on how much people can buy. An example of this is the rationing system that occurred in the Second World War. Because there is a scarcity of food, the government had strict limits on how much people could get. This was to ensure that even people with low incomes had access to food a basic necessity.
A problem of quotas is that it can lead to a black market; for some goods people are willing to pay high amounts to get extra food. Therefore, it can be difficult to police a rationing system. But, it was a necessary policy for second world war.
