 Explanation by concretization works if models and reality share at least a few concrete features. This is arguably the case for many extant models in finance, including models of bubbles and crises that are immediately relevant to explaining the 2008 crisis (Abreu &amp; Brunnermeier 2003). A fairly recent development called “econophysics” may, however, be an exception. Econophysics uses physics methods to model financial markets (see Rickles 2007 for an overview). Where traditional models of crises include individual investors with beliefs and desires modelled by probability distributions and utility functions, econophysics models capture crises the way physicists model transitions of matter from fluid to solid state (Kuhlmann 2014).
