The financial crisis raises questions about the role science can play in the analysis of policy. The rapid decline in market value of individual corporations and the stock market as a whole in 2008 has been variously blamed on mortgage policies, or selling of borrowed securities (short selling) that amplified the impact of mortgage-backed securities. Here we show that crashes are related to panic, characterize the network of economic interdependence and analyze market regulations (the uptick rule).
