We consider impulse control problems motivated from portfolio
optimization with sub-additive transaction cost. We show that the
optimal strategy exists and the number of its jumps is integrable. The
value function is characterized by a new type of Quasi-variational
inequalities. It is a joint work with Jin Ma, Jing Xu, and Jianfeng
Zhang.
