英文摘要:
We solve an exponential utility maximization problem with unbounded payoffs and portfolio constraints, via the theory of quadratic backward stochastic differential equations with unbounded terminal data. This generalizes the previous work of Hu et al. (2005) [Ann. Appl. Probab., 15, 1691--1712] from the bounded to an unbounded framework. Furthermore, we study utility indifference valuation of financial derivatives with unbounded payoffs, and derive a novel convex dual representation of the prices. In particular, we obtain new asymptotic behavior as the risk aversion parameter tends to either zero or infinity.

中文摘要:
我们利用终端数据无界的二次倒向随机微分方程理论,解决了一个具有无界收益和投资组合约束的指数效用最大化问题。这概括了Hu等人(2005)[Ann.Appl.Probab.,15,1691-1712]之前的工作,从有界框架到无界框架。此外,我们还研究了具有无界收益的金融衍生品的效用无差异估值,并推导出了一种新的价格凸对偶表示。特别地,当风险厌恶参数趋于零或无穷大时,我们得到了新的渐近行为。
