Dynamic programming with shape-preserving rational spline Hermite interpolation

Cai, Yongyang; Judd, Kenneth L. - In: Economics Letters 117 (2012) 1, pp. 161-164

Numerical methods for dynamic programming often use value function iteration and interpolation. We present a novel shape-preserving rational spline approximation method that improves value function iteration in terms of both stability and accuracy compared to more common methods.
