英文摘要:
In multi-period stochastic optimization problems, the future optimal decision is a random variable whose distribution depends on the parameters of the optimization problem. We analyze how the expected value of this random variable changes as a function of the dynamic optimization parameters in the context of Markov decision processes. We call this analysis \\emph{stochastic comparative statics}. We derive both \\emph{comparative statics} results and \\emph{stochastic comparative statics} results showing how the current and future optimal decisions change in response to changes in the single-period payoff function, the discount factor, the initial state of the system, and the transition probability function. We apply our results to various models from the economics and operations research literature, including investment theory, dynamic pricing models, controlled random walks, and comparisons of stationary distributions.

中文摘要:
在多周期随机优化问题中,未来的最优决策是一个随机变量,其分布取决于优化问题的参数。我们分析了在马尔可夫决策过程中,这个随机变量的期望值是如何作为动态优化参数的函数变化的。我们把这种分析称为随机比较静力学。我们推导了{比较静力学}结果和{随机比较静力学}结果,表明当前和未来的最优决策如何随单期支付函数、贴现因子、系统初始状态和转移概率函数的变化而变化。我们将我们的结果应用于经济学和运筹学文献中的各种模型,包括投资理论、动态定价模型、受控随机游动和平稳分布的比较。
