That's the fundamental problem with the Keynesian school. You think everything can be broken down into mathematical models. You ultimately fail to understand that human behavior cannot be mathematically modeled over a long enough time horizon. That it is inherently irrational. You don't have to show us the models. Spare me. Please.Would you like to see this expressed in mathematical terms? I could show you. Would that be logical enough for you?
Your school will repeatedly misunderstand the western solvency issue (crisis) as a series of rolling independent liquidity issues until you do figure it out.
