Local (perturbation) methods compute solutions in one point and tend to deliver far lower accuracy levels than global … solution methods. We develop a hybrid method that solves for some policy functions locally (using a perturbation method) and … hybrid method to solve large-scale RBC models used in the comparison analysis of Kollmann et al. (J Econ Dyn Control 35 …

-order perturbation method. The simulation results of impulse responses and second moments match the standardized features of incomplete … market models. Accuracy of the solution is in a reasonable range but significantly decreases when the economy is near the …

This paper describes in detail the algorithm implemented in Dynare for computing the first order approximated solution …

Dynare is a software platform for handling a wide class of economic models, in particular dynamic stochastic general … equilibrium (DSGE) and overlapping generations (OLG) models. The models solved by Dynare include those relying on the rational … expectations hypothesis, wherein agents form their expectations about the future in a way consistent with the model. But Dynare is …

accurately and quickly. We also implement a hybrid solution algorithm that combines the perturbation and accurate intratemporal … approximation methods, fixed-point iteration and efficient integration methods, such as non-product monomial rules and Monte Carlo … integration combined with regression. We show that high accuracy in intratemporal choice is crucial for the overall accuracy of …

We solve a standard New Keynesian model with Epstein-Zin preferences and time …-varying disaster risk with perturbation, Taylor projection, and Smolyak collocation. Our main finding is that Taylor projection … delivers the best accuracy/speed tradeoff among the tested solutions. We also document that even third-order perturbations may …
