We examine the role of borrower concerns about future credit availability in mitigating the effects of adverse selection and income misrepresentation in the mortgage market. We show that the majority of additional risk associated with “low-doc” mortgages originated prior to the Great Recession was due to adverse selection on the part of borrowers who could verify income, but chose not to.

BACKGROUND Recent evidence suggests that National Health Service (NHS) rationing of bariatric surgery is biased toward super-obese patients without scientific basis. The aim of this study was to compare health, quality of life, and employment outcomes in morbidly obese (MO) versus super-obese (SO) patients after laparoscopic Roux-en-Y gastric bypass (LRYGB) to provide a basis for rationing. M...

In this paper, we consider stock rationing problem of a single-item make-to-stock production/inventory system with multiple demand classes. Demand arrives as a Poisson process with a randomly distributed batch size. It is assumed that the batch demand can be partially satisfied. The facility can produce a batch up to a certain capacity at the same time. Production time follows an exponential di...
