This paper shows how the problem of mean-downside risk portfolio allocation can be cast in terms of penalized least squares (PLS). The penalty is given by a power function of the returns below a certain threshold. We derive the asymptotic properties of the PLS estimator, allowing for possible...

Fisheries management is complicated in nearly all cases by various types of uncertainty. Numerous economics and fisheries science publications prescribe adjustments to harvest strategies and regulations in the face of uncertainty. The conclusions and recommendations from this body of work are...

Some have observed that individuals perform worse after being promoted. The Peter Principle, which states that people are promoted to their level of incompetence, suggests that something is fundamentally misaligned in the promotion process. This view is unnecessary and inconsistent with the...

We consider a two-station tandem queueing system where customers arrive according to a Poisson process and must receive service at both stations before leaving the system. Neither queue is equipped with dedicated servers. Instead, we consider three scenarios for the fluctuations of workforce...

This paper reconsiders the question of testing for the presence of Pareto suboptimal capital overaccumulation in overlapping generations economies. The paper allows generation-specific technology shocks to evolve over time according to a stationary Markov chain, and assumes that an...
