SolveDSGE

SolveDSGE is a Julia package for solving Dynamic Stochastic General Equilibrium (DSGE) models. The package is aimed at macroeconomists interested in first-order-accurate or second-order-accurate solutions to their general equilibrium models. SolveDSGE offers a broad array of solution methods that can be applied provided the DSGE model can be expressed in one of several standard dynamic representations.

Installation

You can install SolveDSGE by typing in REPL

Pkg.add("SolveDSGE")

After this you will want to get the latest version from master by typing

Pkg.checkout("SolveDSGE")

First-order-accurate methods

SolveDSGE allows rational expectations equilibria to be computed using a variety of methods. The appropriate method to use depends on how the (linearized) model is expressed. The following model forms are accommodated:

• Blanchard and Kahn (1980)
• Klein (2000)
• Sims (2001)
• Binder and Pesaran (1995)

Second-order-accurate methods

SolveDSGE can also solve DSGE models to second-order-accuracy. The two solution methods that are included are:

• Gomme and Klein (2011)
• Lombardo and Sutherland (2007)

Optimal policy

In addition to solving rational expectations models, SolveDSGE also computes optimal policies for a range of model forms. Specifically, The following policies can be computed for linear-quadratic models

• Discretion
• Commitment
• Quasi-commitment
• Timeless-perspective commitment
