“”” The one thing it never seemed to occur to anyone to do was to get a job at a bank, and find out what actually happens when someone asks to borrow money. In 2014 a German economist named Richard Werner did exactly that, and discovered that, in fact, loan officers do not check their existing funds, reserves, or anything else. They simply create money out of thin air, or, as he preferred to put it, “fairy dust.”””” Let me stop you there. Economists aren’t trying to create the exact theory that market participants implement. That would almost certainly be short sighted to the point of uselessness. (How often in your life have you woken up with Plan A and wound up doing B - where B is very different from A?) Instead, they’re looking for a theory that agrees in the outcome and may be applied usefully to describe what’s going on in resource allocation. This probably flies in the face of a technology focused era in which surveillance of the masses at the nearly perfectly micro/individual level is a prime factor in market valuation. Some of the largest corporations today have access to data no economist ever dared dream to consider. That actually makes me think modern surveillance companies (google, Apple, amazon, etc) could really make market models from the individual to market level in aggregate. Versus the topics at discussion here - which are macroeconomic. Macro is often hurt by a lack of data since there are only so many years of data of the goings ons of nations in a global context - with probably not enough variation to make conclusions.
