Mark-To-Market In A Crisis

Tyler Cowen with another great post, this time on mark-to-market rules:

"Here is Franklin Allen and Elena Carletti, circa 2006:

When liquidity plays an important role as in times of financial crisis, asset prices in some markets may reflect the amount of liquidity available in the market rather than the future earning power of the asset. Mark-to-market accounting is not a desirable way to assess the solvency of a financial institution in such circumstances. We show that a shock in the insurance sector can cause the current value of banks’ assets to be less than the current value of their liabilities so the banks are insolvent. In contrast, if historic cost accounting is used, banks are allowed to continue and can meet all their future liabilities. Mark-to-market accounting can thus lead to contagion where none would occur with historic cost accounting.

Here is a comment on that same paper. I thank Scott Cunningham for the pointer."

This strikes me as a good point, but I still wonder why you couldn't use both, or consider both.
