英文摘要:
Using elementary arguments, we show how to derive $\\mathbf{L}_p$-error bounds for the approximation of frictionless wealth process in markets with proportional transaction costs. For utilities with bounded risk aversion, these estimates yield lower bounds for the frictional value function, which pave the way for its asymptotic analysis using stability results for viscosity solutions. Using tools from Malliavin calculus, we also derive simple sufficient conditions for the regularity of frictionless optimal trading strategies, the second main ingredient for the asymptotic analysis of small transaction costs.

中文摘要:
利用初等变元,我们给出了在具有比例交易成本的市场中,近似无摩擦财富过程的$\\ mathbf{L}\\u p$-误差界的推导方法。对于风险厌恶有界的公用事业,这些估计产生了摩擦值函数的下界,这为使用粘性解的稳定性结果进行渐近分析铺平了道路。利用Malliavin演算的工具,我们还导出了无摩擦最优交易策略正则性的简单充分条件,这是小交易成本渐近分析的第二个主要因素。
