TRADE-OFFS
Economics is concerned with people making decisions.
However, these decisions are not always easy to make as making a decision
involves making a choice. This choice may be between different alternatives/goals/options.
Generally, choosing one goal means not being able to choose the other one. This
results in what we call a trade-off where in order to choose one thing
we have to let go or sacrifice the other one.
Examples of Trade-Offs:
People
face numerous trade-offs in their daily lives. Let’s say a person wants to
reach his office. He may either go by car or bicycle. Going by a bicycle is not
only environmentally friendly but also is a good exercise. However, going by a
car will save time and make him reach faster. This is a situation of trade-off
where the person has to choose an option and in choosing one, he will be giving
up the other one.
A family which has a limited monthly budget has to
decide whether to spend that money on a vacation, saving for their children’s
future or buying a utility good such as a SUV car, T.V etc. Spending more on
the vacation means less money is available for other purposes. Therefore, due
to the limited budget, the family has to make a decision of trading-off one goal
for the other (or spending more on one goal and less on the other)
A student faces a trade-off when deciding which
subject or group of subjects to choose for higher education. As, he/she cannot
choose all the subjects, he/she has to make a choice of choosing one (or a group) and
leaving the rest.
Not only individuals, but nations also face trade-offs.
A country when increasing the money supply may have to face a rise in the
general price level in the economy. Thus, the country faces a trade-off between
increase in money supply and lower prices.
Why do trade-offs arise?
Trade-offs arise because of scarcity of resources. As resources
are scarce or limited, people cannot have everything they want at a given time.
So, they have to choose one option over the other. In case of our examples
discussed in the above paragraph, the family has a limited income at a given
time and has to decide in which way to spend that income, for a student, time
is scarce resource, the farmer has a limited piece of land which ultimately can
be used for only one purpose.
Given that trade-offs exist, how to people then decide
what to choose between different alternatives?
The final decision that people make depends on their
preferences and opportunity cost.
