This article studies the behavior of an individual who can repeatedly alternate between two occupations. Such a career option is analogous to an exotic derivative security: an American reset option. Despite infinite opportunities to change occupations, an individual faced with mobility costs is...

Value-at-Risk and Conditional Tail Expectations are central tools of modern risk management. As risk measures based on the actual probability distribution, these can eventually decrease with the investment horizon. This is not evidence that stock investments are decreasingly risky in the...

Both investor contributions and investment returns determine retirement plan outcomes, but they have distinctive effects over the investor's lifecycle. Focusing on target-date funds (TDFs) in 401(k) plans, our research demonstrates that in the early stage, contributions are the primary...

This paper applies the methods of Detemple, Garcia, and Rindisbacher (2003, 2005) to derive optimal lifetime consumption-portfolio plans in an economy characterized by a N- factor Heath-Jarrow-Morton (1992) bond sector that is Markovian with respect to 3N state variables. The...

Over the past decade, risk measurement has received a much needed amount of attention from the .nancial community. Risk measures based on .xed quantiles un- der the actual probability distribution, especially Value-at-Risk and its re.nement the Conditional Tail Expectation, were instrumental in...

Research fads, which create bubbles in academia, gobble up resources and crowd out exploration of competing ideas. Investment-related academic bubbles have a cost. In the best case, money is lost by investors chasing fragile ideas. In the worst case, the general public suffers real pain when the...

This paper applies the methods of Detemple, Garcia, and Rindisbacher (2003, 2005) and derives explicit optimal lifetime consumption-portfolio plans in an economy whose fixed-income sector is characterized by an N-factor Heath-Jarrow-Morton (1992) model that is Markovian in 3N state variables
