十分感谢回复 dr algo = 0 or 1: species the algorithm used for computing the quadratic
approximation of the decision rules: 0 uses a pure perturbation approach
as in Schmitt-Grohe and Uribe (2004) (default) and 1 moves the point
around which the Taylor expansion is computed toward the means of
the distribution as in Collard and Juillard (2001b).

根据你提供的资料,可以看出这个选项是指定计算2阶近似解,即决策规则,就是policy function时所使用的方法。0就是那篇著名的二阶算法,Schmitt-Grohe and Uribe (2004) ,这是缺省值,展开的点应该是稳态值,纯扰动算法。1是使用Collard and Juillard (2001b). 这个展开的点似乎向均值移动,这篇文章没看过,你可以仔细看看。
