Change in Market Assessments of Deposit-Institution Riskiness
NBER Working Paper No. 2530
Using the Goldfeld and Quandt switching regression method, this paper investigates variability over 1975-85 in the risk components of bank and saving and loan stock. We develop evidence that the market-beta, interest-sensitivity, and residual risk of deposit-institution stock vary significantly during this period. Reassessing previous event studies in light of these findings suggests that event-study methods tend to overreach their data.
