“I’ve consistently said that when we looked at our financial institutions,” Secretary of the Treasury Henry Paulson said Monday, “the root of the problem lies in this housing correction.” Housing prices went up — and banks and other financial institutions invested in mortgages. Housing prices went down — and banks and other financial institutions failed.
Why did housing prices go up? Because of supply constraints. We know that home builders can meet almost any demand if there are no constraints on land. We know that because, as the latest home price indices reveal, the fastest growing metropolitan areas in America — places like Dallas and Houston — did not suffer from housing bubbles and are not now suffering any serious correction.
