Well those are all measurable quantities, and you can measure them in proportion to their economic importance - like house insulation is a big change if you live in cold climate, etc.
I am not saying it’s easy, but economics is full of complex measurements, financial derivatives, and god knows what. Maybe they should spend some effort measuring the real world.
