I will be writing a series of articles concerning the three mortgage fraud epidemics that hyper-inflated the bubble and drove the financial crisis prompted by four recent economic studies of mortgage fraud. My goal is to integrate the results of those studies with the work of criminologists, investigators, and data from other sources such as Clayton.
In economics and white-collar criminology, we teach our students the very useful concept of “revealed preferences.” We take what potential perpetrators say they would do and why they claim they took an action with cartons of salt. Their actions generally speak far louder and more candidly than do their words. I will show in this series how valuable revealed preferences are in analyzing the data and testing rival research hypotheses. (I will explain why I feel the recurrent failure to state these hypotheses expressly leads to serious error.)
I have come to the view that a concept that I term “revealed biases” is a useful corollary to “revealed preferences.” The National Institute of Justice virtually never funds empirical studies of elite white-collar criminals (a classic “revealed bias”). OMB suggests research programs exclusively for blue collar crime – in the midst of the largest and most destructive epidemics of elite white-collar crime in history. I wrote my first column in this series about an example of revealed biases in discussions of econometric studies of mortgage fraud.
