主题：Default Option Exercise over the Financial Crisis and Beyond（金融危机期间及之后的违约期权履约）
We document increased ruthlessness of mortgage default option exercise over the financial crisis. Findings show that the marked upturn in default option exercise was even more important to crisis period defaults than was the collapse in home equity. Analysis further indicates that much of the variation in default ruthlessness can be explained by the local business cycle, house price expectations, and consumer distress. Also, results suggest elevated default option exercise in the wake of enactment of crisis-period loan modification programs.
