Economic shortageFrom Wikipedia, the free encyclopedia
An economic shortage is a disparity between the amount demanded for
a product or service and the amount supplied in a market. Specifically, a shortage occurs when
there is excess demand; therefore, it is the opposite of a surplus.
Economic shortages are related to price—when the price of an item is set below
the equilibrium rate determined by supply and demand, there will be a shortage. In most cases,
a shortage will compel firms to increase the price of a product until it reaches market
equilibrium. Sometimes, however, external forces cause more permanent shortages—in other
words, there is something preventing prices from rising or otherwise keeping supply and
demand balanced.
In common use, the term "shortage" may refer to a situation where most people are unable to
find a desired good at an affordable price. In the economic use of "shortage", however, the
affordability of a good for the majority of people is not an issue: If people wish to have a certain
good but cannot afford to pay the market price, their wish is not counted as part of the quantity
demanded at that price.

Effects[edit]
In the case of government intervention in the market, there is always a trade-off with positive
and negative effects. For example, a price ceiling may cause a shortage, but it will also enable a
certain percentage of the population to purchase a product that they couldn't afford at market
costs. Economic shortages caused by higher transaction costs and opportunity costs (e.g., in
the form of lost time) also mean that the distribution process is wasteful. Both of these factors
contribute to a decrease in aggregate wealth.
More generally, regardless of their cause, shortages may result in:
Black markets - illegal markets in which products that are unavailable in conventional
markets are sold, or in which products with excess demand are sold at higher prices than in
the conventional market.
Artificial controls on demand, such as rationing.
Non-monetary bargaining methods, such as time (for example queuing), nepotism, or even
violence.
Price discrimination
The inability to purchase a product.
Examples[edit]
In the former Soviet Union during the 1980s, prices were artificially low by fiat (i.e., high
prices were outlawed). Soviet citizens waited in line (or "queued") for various price-
controlled goods and services such as cars, apartments, or some types of clothing. From
the point of view of those waiting in line, such goods were in perpetual "short supply"; some
of them were willing and able to pay more than the official price ceiling, but were legally
prohibited from doing so. This method for determining the allocation of goods in short
supply is known as "rationing".
Other examples of economic shortages include:
1973 oil crisis , during which long lines and rationing were used to control demand.
Prohibition , which resulted in the creation of a black market for liquor.
Whether an economic shortage of a certain good or service is beneficial or detrimental to
society often depends on one's ethical and political views. For instance, consider the shortage
of recreational drugs discussed above, and the controversies around the use of such drugs.
Likewise, consider the economic shortage of cars in the Soviet Union during the 1980s: On the
one hand, people had to wait in line to buy a new car; on the other hand, cars were more
affordable than they would have been at market prices.
