Positive economics as a science concerns the investigation of economic behavior. [4] It deals with empirical facts as well as cause-and-effect relationships. It emphasizes that economic theories must be consistent with existing observations and produce precise, verifiable predictions about the phenomena under investigation.

The Lorenz curve is invariant under positive scaling. If X is a random variable, for any positive number c the random variable c X has the same Lorenz curve as X. The Lorenz curve is flipped twice, once about F = 0.5 and once about L = 0.5, by negation. If X is a random variable with Lorenz curve L X (F), then −X has the Lorenz curve:
Economic methodology has gone from periodic reflections of economists on method to a distinct research field in economics since the 1970s. In one direction, it has expanded to the boundaries of philosophy , including the relation of economics to the philosophy of science and the theory of knowledge . [ 18 ]
