Examining The Market Reactions To Regulatory Accounting Events

Abstract

Evaluation of market reaction to regulatory accounting events such as the accounting standards policy setting process has commonly utilized event study methodology. However, this methodology quite often has resulted in inconsistent and conflicting findings due to partial anticipation of the events being examined and due to nonstationarity of the parameters in the estimation model. A multi-regime market model based methodology that allows for the proper treatment of these problems is proposed and is illustrated with an application in the policy setting process for SFAS No. 8.
