The author rejects the usual division of economics (Positive Economics versus Normative Economics). Since actions and perceptions are not contrary but complementary phases of the same process such an economics seems to be right which is able to serve both economic actions and perceptions. The author argues for the utilization of the Action Research and Evaluation Research methodologies in economics. In the light of these methodologies the constructive and valuative aspects of economics are desirable. Constructive economic researches discover, new earlier non-existent possibilities for the economic activities. Valuative economic researches explicitly valuate the ways economic activities actually run. Constructive and Valuative Economics seems to be appropriate for making of a better economic world than we live in now.
