We show that by modeling the time series of mortality rate changes rather than mortality rate levels we can better model human mortality. Leveraging on this, we propose a model that expresses log mortality rate changes as an age group dependent linear transformation of a mortality index. The...

Performance fees that are designed to incentivize money managers to exert more effort may also distort a manager's risk choices. In this paper, we analyze the impact of the standard performance fee contract that includes what is known as a high-water mark provision. We investigate the effect the...

We consider the problem of finding optimal exercise policies for American options, both under constant and stochastic volatility settings. Rather than work with the usual equations that characterize the price exclusively, we derive and use boundary evolution equations that characterize the...

Most academic studies on interest rate dynamics and derivative pricing assume that interest rates move freely in an open market, while there has been relatively little attention paid to the situation where a nation's central bank has the power to intervene in the interest rate market. This paper...
