Abstract

В работе обсуждается проблема соответствий между шкалами оценок кредитной привлекательности ведущих международных рейтинговых агентств: Moody's, Fitch и Standard&Poor's (S&P). В результате краткого обзора существующих методологических подходов к решению данной проблемы в исследовании предложен новый метод, базирующийся на теории бинарных отношений и функций выбора по векторному критерию. В качестве отношения предпочтения рассматривается отношение строгого порядка, порожденное вероятностью дефолта, а в качестве эталонной меры выбирается специально вводимый рейтинг как результат ранжирования по Парето многомерных параметров текущих оценок Moody's, Fitch и S&P. При этом сама механика присвоения рейтингов тем или иным международным агентством в данном подходе оказывается неважна, что нивелирует зависимость от политического ангажирования экспертных оценок. Естественно, подобное расширение не может приводить к взаимной однозначности шкал и поставляет взамен их вероятностное соответствие.
