Small noise methods for risk-sensitive/robust economies

Evan Anderson, Lars Hansen and Thomas Sargent ()

Journal of Economic Dynamics and Control, 2012, vol. 36, issue 4, 468-500

Abstract: We provide small noise expansions for the value function and decision rule for the recursive risk-sensitive preferences specified by Hansen and Sargent (1995), Hansen et al. (1999), and Tallarini (2000). We use the expansions (1) to provide a fast method for approximating solutions of dynamic stochastic problems and (2) to quantify the effects on decisions of uncertainty and concerns about robustness to misspecification.
