We consider a utility-maximization problem in a general semimartingale financial model, subject to constraints on the number of shares held in each risky asset. These constraints are modeled by ...

We design a dynamic rate scheduling policy of Markov type by using the solution (a social optimal Nash equilibrium point) to a utility-maximization problem over a randomly evolving capacity set for a ...

Several weeks ago, an article ran in Inside Higher Ed about the interest of many graduate students in jobs that don’t include a lot of pressure to publish. Instead many were interested in jobs that ...
