Brian Wesbury and Bob Stein make yet another strong argument against the mark-to-market accounting regime:
The history seems clear. Mark-to-market accounting existed in the Great Depression, and according to Milton Friedman, who wrote about it just 30 years after the fact, it was responsible for the failure of many banks.
Franklin Roosevelt suspended it in 1938, and between then and 2007 there were no panics or depressions. But when FASB 157, a statement from the Federal Accounting Standards Board, went into effect in 2007, reintroducing mark-to-market accounting, look what happened.
Two things are absolutely essential when fixing financial market problems: time and growth. Time to work things out and growth to make working those things out easier. Mark-to-market accounting takes both of these away.
