Finance Theory and Accounting Policy
Amid the financial crisis, considerable debate attends the enduring validity of Modern Finance Theory, including assumptions of capital market efficiency, reliability of recognized risk measurement tools and models of risk reduction through diversification. There’s little doubt that MFT has had considerable effects on positive law and legal scholarship in the past three generations. Looming are questions about whether those policies warrant reconsideration given ongoing discoveries of potential deficiencies in those models.
Some of these implications appear in contexts covered by the broad subject called Law and Accounting, topics within securities regulation, corporation law and financial reporting policy. In writing a paper addressing the influence of MFT on L&A, I’m trying to identify the most significant subjects. In outlining a draft, I’ve identified the following as the most consequential, and would be delighted to hear, through comment or email, alternative suggestions or criticisms of this initial compilation.
The following is a top ten list of subjects in Law and Accounting that Modern Finance Theory has influenced. In each case, it is difficult to deny the role MFT had in augmenting legal or policy change. In some cases, there is little doubt this has been an improvement but in others the resulting law or policy backfired or is of contested appeal. On balance, the influence of MFT on L&A warrants an uncertain appraisal, with many positive effects along with some offsets.
An interesting issue in each case is how, if at all, changing confidence levels in the validity of MFT would warrant changing the related policy. Notably, at least some of the policies could remain justifiable even were MFT deemed invalid. The appeal of others depends quite heavily on its validity.
