Take the following as truth: So-called new Keynesian economists provided at least a theoretical fig leaf for more or less Keynesian ideas, and in practical terms the intellectual basis of modern U.S. monetary and fiscal policy is pretty much what was already in the textbooks 20 years ago.
Then the following statement: "Keynesian economics is a very specific branch of economics that not many deal with" is true, false, or inconclusive?
Answer: Inconclusive
