Final answer:
Positive statements are factual and can be tested for truth, while normative statements are based on values and cannot be proven true or false. An op-ed advocating for an economic policy is generally a normative statement.
Step-by-step explanation:
In economics, there is a clear distinction between two types of statements: positive statements and normative statements. Positive statements are factual and can be tested to be true or false. For instance, asserting that a proposed subway system will bring more benefits than costs is an example of a positive statement because it is based on an analysis of factual data. Conversely, normative statements are subjective, based on opinions or values, and cannot be proven true or false. For example, the view that a wealthy nation should provide for its less fortunate citizens is a normative statement because it is based on value judgments about what should happen.
An op-ed piece in a newspaper that urges the adoption of a particular economic policy is typically a normative statement. This is because it expresses an opinion or recommendation on what the policy should be, reflecting the author’s values or beliefs on the matter.
