The trouble with economics, though, is the assumption of the Rational Man at the center of it.
When economics is utilized as a useful tool (talk about equivalent: UTILIZED… USEFUL …. TOOL …. that sentence fragment beats the point to death)….
…it can be helpful in decision-making. But answers requires not only a multitude of disciplines coming together, it ultimately requires going BEYOND any individual or combination of disciplines to get a “big picture”; which is, ultimately, a story that ties them together.
Even THEN there’s the application… and it’s in the application that the rubber meets the road. Still, getting things perfected in models is very useful.
