We show that the standard Value Function Iteration (VFI) algorithm has difficulties approximating models with jump discontinuities in policy functions. We find that VFI fails to accurately identify the location and size of jump discontinuities while other methods - such as the Endogenous Grid...

We present a new approach to the approximation of equilibrium solutions to nonlinear rational expectations models that applies to any order of approximation. The approach relies on a particular version of Taylor series approximations - the differential version - and on a scalar perturbation of...

We compare the performance of the perturbation-based (local) portfolio solution method of Devereux and Sutherland (2010a, 2011) with a global solution method. We find that the local method performs very well when the model is designed to capture stylized macroeconomic facts and countries/agents...

Using a stylized two period model we obtain portfolio solutions from two solution approaches that belong to the class of local approximation methods – the approach of Judd and Guu (2001, hereafter ’JG’) and the approach of Devereux and Sutherland (2010, 2011, hereafter ’DS’) – and...

The paper studies how high household leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of high-income households, a large increase in debt leverage of the...

This paper defines a monetary equilibrium and computes an optimal nonlinear, full-information, state-dependent monetary policy rule to which the monetary authority commits at the beginning of time. This type of optimal monetary policy represents a combination of the flexibility of discretion...
