Normative and Positive Statements
Two
kinds of assertions in economics can be subjected to testing. One of it
is a statement of fact, such as “It is raining outside” or “India has
an unemployment rate of 9%.” Like hypotheses, such assertions can be
demonstrated to be false. Unlike hypotheses, they can also be shown to
be correct. A statement of fact or a hypothesis is a positive statement.Although people often disagree about positive statements, such disagreements can ultimately be resolved through investigation.
There is another category of assertions, however, for which investigation can never resolve differences. A normative statement is one that makes a value judgment. Such a judgment
is the opinion of the speaker; no one can “prove” that the statement is
or is not correct. Here are some examples of normative statements in
economics: “We ought to do more to help the poor.” “People in the United
States should save more.” “Corporate profits are too high.” The
statements are based on the values of the person who makes them. They
cannot be proven false.
Because people have different values, normative statements often provoke disagreement.
An economist whose values lead him or her to conclude that we should
provide more help for the poor will disagree with one whose values lead
to a conclusion that we should not. Because no test exists for these
values, these two economists will continue to disagree, unless one
persuades the other to adopt a different set of values. Many of the
disagreements among economists are based on such differences in values
and therefore are unlikely to be resolved.
