When a leveraged real estate project experience cash-flow problems, the owner must either inject additional cash or default on the mortgage. We show that it is not optimal for the owner to default as soon as net cash flow becomes negative. Surprisingly, the owner can expropriate some of the...

Although traded as distinct products, caps and swaptions are linked by no-arbitrage relations through the correlation structure of interest rates. Using a string model framework, we solve for the correlation matrix implied by the swaptions market and examine the relative valuation of caps and...

This paper studies the valuation and optimal exercise of American-style swaptions in a multi-factor string model of the term structure, and compares the results with those implied by standard single-factor term structure models. We find that single-factor models significantly undervalue...
