The present paper is devoted to the study of a bank salvage model with a finite time horizon that is subjected to stochastic impulse controls. In our model, the bank’s default time is a completely inaccessible random quantity generating its own filtration, then reflecting the unpredictability...

We consider optimal dividend payment under the constraint that the with-dividend ruin probability does not exceed a given value α. This is done in most simple discrete De Finetti models. We characterize the value function V(s,α) for initial surplus s of this problem, characterize the...

This paper studies the impacts of an environmental bond, which fully covers waste cleanup costs, on a mining firm's optimal actions over the full life cycle of a mine, when bankruptcy may shift cleanup costs to the government. A firm's stochastic optimal control problem is described by an HJB...
