Macro vs micro

The issue for economists is to derive an individual model  which integrates into the macro model. So they ask, what information does the household or firm have.

Our model says, that works when information is used to plug the uncertainty leaks of life. If the underlying process supports the information model, the the underlying process is a queuing stabilization process.  The claim to fame of the basket brigade theory.

Another model is Euler, the agent can pick a real destination by choosing his rate of change.  This requires infinite compressibility of transactions, the ability to by carton of five eggs, when needed. Information model won't match, as information is finite, in the aggregate, and a queuing theory. We manage its precision, but we assume this is all about queuing.

The Euler model is an algorithm that takes a finite generator and steps it out recursively, becoming more accurate at each increment.  A recursive algorithm, about which mathematicians have some grammar.  Has little relevance to natural queuing processes.

Egg cartons explain it all

It is exactly what we do, egg cartons.  In our model, the agent is stuck, maybe, he can by 6 eggs to a carton, only.  The agent uses household inventory uncertainty to privately plan breakfast menus, and will restock eggs in a day or two.

The Euler model says the agent will buy the number of eggs needed for the current breakfast plan. 

The brigade theory tracks, and accumulates,  that inventory uncertainty, but we become finite, and our generators do not have a complete inverse.
