Mathematicians talk about
axioms, integrals, and vector spaces
. Psychologists talk
about
ego, id, and cognitive dissonance
. Lawyers talk about

Economics is no different. Supply, demand, elasticity, comparative advantage,
consumer surplus, deadweight loss
鈥攖hese terms are part of the economist鈥檚 language.
In the coming chapters, you will encounter many new terms and some familiar words
that economists use in specialized ways. At first, this new language may
seem
needlessly arcane.
But, as you will see, its value lies in its ability to provide you
a new and useful way of thinking about the world in which you live.

Economists try to address their subject with a scientist鈥檚 objectivity.
They
approach
the study of the economy in much the same way a
s a physicist
app
roaches the study of matter an
d a biologist app
roaches the study of life:
They
devise
theories, collect data, and then analyze these data in an attempt to verify
or refute their theories.
