The average credit score of today's FHA borrowers is higher than the average American household with a score. As it becomes more costly and difficult to get a FHA loan, loans from private mortgage lenders will become more attractive and their market share will grow.

They called me the sexiest economist in America, and that was years ago, when I had hair and body mass and my teeth were shiny.

It is hard to be enthusiastic about the economy's prospects when house prices are falling: Households spend less, small business owners can't use homes as collateral for loans and local governments are forced to cut jobs and programs as property-tax revenue disappears.

In a forbearance, the homeowner pays interest and principal on a smaller mortgage, at least for a time, but still owes the full amount. The lower monthly payment helps with affordability, giving stressed homeowners a break.

The FHA's success provides strong evidence that government can and should play a role in the nation's mortgage finance system. It also demonstrates that although government intervention in the economy during the Great Recession was messy, things would have been a lot messier without it.

There is no better way to quickly buoy hard-pressed homeowners than helping them take advantage of the currently record low fixed mortgage rates and significantly reduce their monthly mortgage payments.

It has become fashionable to rail against government intervention in the economy, and the FHA is a favorite example by those trying to show the government's overreach. In reality, the FHA shows how government action during the Great Recession forestalled a much worse economic fate.
