Reviving the housing market, the supply side

I have given my take on the demand side policies.

Mankiw noted some supply side plans:

• the shared appreciation mortgage, or SAM, in which the homeowners who get a mortgage relief will have to forfeit the future appreciation on their house.
• Zingales's Plan B, which is essentially an equity-for-debt swap.

The problem, it is hard to renegotiate the mortgage contract as we have noted before. Then it is still easier to implement the demand side policies.
