Hann et al. (2007) found empirical evidence of
fair-value pension accounting not improving the informativeness of the financial
statements and even impairing it. Slightly related to these issues, Beaver et al. (2005)
found a small decline in the ability of financial ratios to predict bankruptcy from 1962
to 2002, and an incremental explanatory power of market-related variables over this
period. They explain the deterioration of predictive ability of financial ratios in terms of
an insufficient improvement of FASB standards.
