英文摘要:
Game contingent claims (GCCs) generalize American contingent claims by allowing the writer to recall the option as long as it is not exercised, at the price of paying some penalty. In incomplete markets, an appealing approach is to analyze GCCs like their European and American counterparts by solving option holder\'s and writer\'s optimal investment problems in the underlying securities. By this, partial hedging opportunities are taken into account. We extend results in the literature by solving the stochastic game corresponding to GCCs with both continuous time stopping and trading. Namely, we construct Nash equilibria by rewriting the game as a non-zero-sum stopping game in which players compare payoffs in terms of their exponential utility indifference values. As a by-product, we also obtain an existence result for the optimal exercise time of an American claim under utility indifference valuation by relating it to the corresponding nonlinear Snell envelope.

中文摘要:
游戏未定权益(GCC)概括了美国的未定权益,允许作者在未行使期权的情况下收回期权,代价是支付一些罚金。在不完全市场中,一种很有吸引力的方法是通过解决期权持有人和写入人在标的证券中的最优投资问题来分析GCC,就像他们的欧洲和美国同行一样。因此,考虑了部分对冲机会。我们通过求解同时具有连续时间停止和交易的GCC对应的随机博弈,扩展了文献中的结果。也就是说,我们通过将博弈改写为一个非零和停止博弈来构建纳什均衡,在这个博弈中,参与者根据其指数效用无差异值来比较收益。作为一个副产品,我们还通过将其与相应的非线性Snell包络联系起来,得到了效用无差异估价下美式索赔最优行使时间的存在性结果。
