QUOTE : What if we looked at the law as a piece of software, the operating system of the United States of America. After all, laws play the same role as software in providing instructions for a given system - if this, then that, and so on. If a team of software engineers was asked to analyze the entire body of federal law, they would see tens of thousand of pages of poorly documented code, with a multitude of complex, spaghetti-like interdependencies between the individual components. Could the principles of good software design be used to improve the way we write financial regulations?<br /><br />Li, William, Pablo Azar, David Larochelle, Phil Hill, and Andrew W. Lo. 2015.

Like an epidemiologist studying the spread of a contagious disease from its point of origin, we should identify the potential linkages through which a financial crisis may travel.<br /><br />Billio, Monica, Mila Getmansky, Andrew W.

The idea is to see how macroeconomic problems facing countries might get transmitted to the financial system and vice versa.<br /><br />Billio, Monica, Mila Getmansky, Dale Gray, Andrew W.
