This paper explores the practice of mortgage refinancing in a dynamic competitive lending model with risky borrowers and costly default. We show that the prepayment penalties are welfare improving, and that they are more beneficial to borrowers with higher risk of default. The empirical evidence...

the market interest rate is low. Thus, our analysis provides theoretical evidence that these alternative mortgages, which have recently generated great controversy, can benefit both lenders and borrowers.

include constraints to limit the loss faced by the underwriter for an early first default. In this more complicated setting, a simple implementation using a CDS and a risk free bond persists.

We show that prepayment penalties improve welfare by ensuring longer-term lending contracts, which prevents the mortgage pools from becoming disproportionately...

We develop a tractable general equilibrium framework of housing and mortgage markets with aggregate and idiosyncratic risks, costly liquidity and strategic defaults, empirically relevant informational asymmetries, and endogenous mortgage design. We show that adverse selection plays an important...
