When borrowers owe more than their homes are worth, they have considerable incentive to simply walk away. These defaults result in further declines in home prices.

Martin Feldstein, a professor of economics at Harvard University and economic adviser to the Reagan administration, says he has a plan that will encourage underwater borrowers to continue paying, reported WSJ.

For any home owner with a loan-to-value ratio greater than 120 percent, Feldstein would offer a reduction in principal, the cost of which would be shared between the government and the lender down to the 120 percent level. In exchange, the borrower would accept a recourse loan that could not be discharged by bankruptcy.

He argues that this plan would stabilize the housing market and cap housing prices at the current level.
