英文摘要:
  This paper studies convex duality in optimal investment and contingent claim valuation in markets where traded assets may be subject to nonlinear trading costs and portfolio constraints. Under fairly general conditions, the dual expressions decompose into tree terms, corresponding to the agent\'s risk preferences, trading costs and portfolio constraints, respectively. The dual representations are shown to be valid when the market model satisfies an appropriate generalization of the no-arbitrage condition and the agent\'s utility function satisfies an appropriate generalization of asymptotic elasticity conditions. When applied to classical liquid market models or models with bid-ask spreads, we recover well-known pricing formulas in terms of martingale measures and consistent price systems. Building on the general theory of convex stochastic optimization, we also derive optimality conditions in terms of an extended notion of a \"shadow price\".

中文摘要:
本文研究了在交易资产可能受到非线性交易成本和投资组合约束的市场中,最优投资和未定权益估值的凸对偶问题。在相当一般的条件下,对偶表达式分解为树项,分别对应于代理的风险偏好、交易成本和投资组合约束。当市场模型满足无套利条件的适当推广,且代理人的效用函数满足渐近弹性条件的适当推广时,对偶表示是有效的。当应用于经典的流动市场模型或具有买卖价差的模型时,我们根据鞅测度和一致价格系统恢复了著名的定价公式。基于凸随机优化的一般理论,我们还根据“影子价格”的扩展概念推导了最优性条件。
