It is certainly impossible to create realistic models of the economy, if one's economics is based on assumptions of linearity and equilibrium. Mark Buchanan's book _Forecast_ [0] makes the case for more realistic models, using techniques from the natural sciences, that would have better predictive value.

Is he rich from his superior models?

[gshubert17]

Good question. The book's blurb says he is a science writer; I don't know how rich he is.

I guess it's easier to point out the flaws in linear, equilibrium models, and to point to better results in, say, meteorology, from using better models based on different assumptions, than it is to construct and validate completely new economic models.
