Taxation Problems in the Dual Model with Capital Injections

该文在带注资的对偶模型中研究征税问题.假设税按照loss-carry-forward制度支付.当盈余低于0时,将采取注资的方式使得盈余达到0而不致破产.假设收益服从指数分布,得到了期望折现征税总额减去期望折现注资成本总额的显式表达式.

This paper studies the taxation problems in the dual model with capital injections. Assume that the taxes are paid according to a loss-carry-forward system. Let the surplus attain 0 avoiding ruin by capital injections when the surplus becomes negative. The explicit expression for the expected discounted tax payments minus the expected discounted costs of capital injections is obtained under the assumption that the gains are exponentially distributed.
