In economics and philosophy, a positive statement concerns what "is", "was", or "will be", and contains no indication of approval or disapproval (what should be). Positive statements are testable - or, at least, it is possible to imagine facts that disprove them - but can be factually incorrect: "The moon is made of green cheese" is empirically false, but is still a positive statement, as it is a statement about what is, not what should be.
