The Positive and Normative Economics

The objective to the success of a specific science is the capability to identify and delineate opinions on 'what is' from 'what ought to happen'.  This includes providing a demarcation between positive statements and normative statements.  Positive statements deal with 'what is, was or what will be' but the normative statements deals with 'what ought to be' and are based on value judgments regarding what is good or what is bad. The positive conclusions could be considered as those which are extensively applicable throughout the whole world and they are testable whereas the normative instructions are not testable but constitute the basis for formulation of positive statements.

Normative statements could generate positive hypothesis regarding the basis on which 'ought'-type conclusion depends on.  It thus helps the policy decision makers to provide for the maximum well-being of all people.
