> Human beings are complicated and difficult to study Well that's a positive way to put it. I wonder whether it is possible to find steady cause and effect patterns at all. Same goes for economy (which IS basically a proxy for human behavior). You can certainly have a go at documenting its history but the present and future are probably not predictable because they are subject to evolutionary responses. When I had to take an economics 101 class negative interest rates were out of the question and look what we have now.
