Early-warning systems are intended to provide regulators with identification of problem institutions sooner than is possible with the present system of call reports and periodic on-site examinations. Given an earlier indication of potential problems, resources can be focused on those institutions most in need of monitoring, thus potentially reducing both the number of failures and FSLIC financial assistance in the remaining failures. While some early-warning systems were developed in the mid-1970s for use by commercial bank regulators, very little attention has been focused on developing similar systems for the thrift industry. To address this issue, multiple discriminant analysis was used to develop an early-warning system for savings and loan associations in the Boston district of the Federal Home Loan Bank system. The results suggest that use of this model would have given signals of impending trouble well before the actual failure occurred. Consequently, an early-warning system could provide information to regulators sooner, permitting scarce resources to be allocated more effectively. In addition, earlier intervention could reduce the amount of FSLIC financial assistance required. By intervening earlier, FSLIC may be able to arrest the failure-promoting activities in which the association is engaged. Copyright American Real Estate and Urban Economics Association.
Using Bank of America/Merrill Lynch bond yield indexes, we compare the returns on investment-grade bonds to the returns on high-yield bonds over the period from January 1997 through mid-August 2011, a period marked by the collapse of the technology sector in early 2000 and the financial crisis in 2008. We compare return and risk measures under the assumption of a normal distribution with those obtained under the assumption of a stable distribution. When a normal distribution is assumed, we see a higher expected return associated with a lower SD on the high-yield bond returns relative to investment-grade bond returns. However, we also find that the returns on both high-yield bonds and investmentgrade bonds exhibit stable (fat-tailed) distributions, with the fat tail more pronounced for the high-yield bond series. These results suggest that the assumption of a distribution that allows for fat tails and skewness is important for identifying the risk and return characteristics of these bond series.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
