Positive economics as such avoids economic value judgments. For example, a positive economic theory might describe how money supply growth affects inflation, but it does not provide any instruction on what policy ought to be followed. An example of a normative economic statement is as follows:
The essay argues that economics as science should be free of normative judgments for it to be respected as objective and to inform normative economics (for example whether to raise the minimum wage). Normative judgments frequently involve implicit predictions about the consequences of different policies.
Statements of fact (positive or descriptive statements), which are based upon reason and observation, and examined via the empirical method. Statements of value (normative or prescriptive statements), which encompass ethics and aesthetics , and are studied via axiology .
In economics, a normal good is a type of a good which experiences an increase in demand due to an increase in income, unlike inferior goods, for which the opposite is observed. When there is an increase in a person's income, for example due to a wage rise, a good for which the demand rises due to the wage increase, is referred as a normal good.
Conclusions from the following economic experiments indicate that economic agents use normative ethics in making decisions while also seeking to maximise their payoffs. [36] For example, in experiments on honesty, it is predicted that lying will occur when it increases these payoffs notwithstanding the results, which proved otherwise. [36]
Normative judgments can be made as well by asking questions like whether the gap of the distribution of wealth and income and social justice. Theoreticians regularly try to evaluate both the positive and normative aspects of the economic system in general and they do so by making assumptions about the rules of the game governing utility-seeking.
An economic ideology is a set of views forming the basis of an ideology on how the economy should run. It differentiates itself from economic theory in being normative rather than just explanatory in its approach, whereas the aim of economic theories is to create accurate explanatory models to describe how an economy currently functions.
So, for example, a positive economic analysis of tort law would predict the effects of a strict liability rule as opposed to the effects of a negligence rule. Positive law and economics has also at times purported to explain the development of legal rules, for example the common law of torts, in terms of their economic efficiency.
