In the following codes, I employ two methods to solve rational expectations models. The resolution is performed via the dynare package requires Matlab or octave initially developed by Michel Juillard. All theses codes are based on the generalized Schur form to solve a systems of linear expectational difference equations. The Cobb-Douglas production function now combines labor, physical capital and technology to produce goods: where is an IID exogenous disturbance associated with a productivity shock. This feature captures the autocorrelation of consumption observed in the data. Thus the utility function subject to external habits reads as follows: RBC Model with investment adjustment costs Dynare Codes Matlab Codes To introduce asset price fluctuations, households supplying investment goods face an investment adjustement costs given by: The law of motion of capital with investment adjustment costs is defined by: These costs drive a wedge between the price of assets and goods and offer a tradeoff beetwen capital goods and riskless bonds.

It aims at demonstrating Dynare best practices and providing tractable replication files for important models that can be useful for further model development.
The headers of the respective mod-files also note obvious mistakes and typos in the respective papers. These mod-files have been tested against Dynare 4. Compatibility with earlier versions is not guaranteed. For Dynare 4. Contributions of replication files to this collection are highly welcomed. When doing do, e. This mod-file shows how to access steady state variables in order to plot steady state dependences on parameters.
It also shows how to manually do a stability mapping be iterating over a grid on the parameter space. This mod-file shows how to deal with trend growth and how to recover the non-stationary variables from the detrended model variables.
This mod-file shows how to estimate a model solved with third order perturbation using the Simulated Method of Moments. It also shows how to generate IRFs at the stochastic steady state ergodic mean in the absence of shocks EMAS in the terminology of the paper.
For practical purposes it is highly recommended to use the standard Andreasen et al. This mod-file shows how to use auxiliary variables to deal with recursive preferences and expected returns. Replicates Chari, V. It demonstrates how to use the linearized benchmark model estimated using Maximum Likelihood to conduct the Business Cycle Accounting as is done in the paper for the recession.
This file was written together with Lahcen Bounader. Please see the header of the mod-file for additional remarks. When doing so, it corrects issues with the original calibration of Gali Implements the welfare analysis of Chapter 4. It shows how to solve a perfect foresight model with a Levenberg-Marquardt mixed complementarity problem lmmcp approach to deal with the zero lower bound on interest rates.
It provides a replication code for the main results of the original paper for the case of Argentina. Replicates the model studied in Hansen, Gary D. Provides replication files for Pfeifer, Johannes : "Macroeconomic effects effects of financial shocks: A comment", Dynare Working Paper It allows replicating the original results and generates the results of Pfeifer , who documents a mistake in the TFP-construction of JQ that requires recalibrating the model.
The driving processes are estimated as AR 1 -processes on linearly detrended data. It does so by defining welfare recursively in the model block and calling an optimizer to find the parameter for the steady state tax rate that maximizes welfare.
It shows how to generate IRFs to a "pure" news shock where an 8 period anticipated news shock does not materialize at time 0. This is the type of policy experiment that is for example performed in Beaudry Portier : An exploration into Pigou's theory of cycles, Journal of Monetary Economics 51, pp. Rudimentary code that is compatible with Dynare 4. Provides replication files that are compatible with Dynare 4. Various mod-files related to the basic Solow-Swan model, using Dynare's perfect foresight routines to study steady state transitions when e.
Studies the transition behavior of a simple Solow-Swan economy with Cobb-Douglas production function to its steady state when started with a capital stock different from steady state. Studies the transition behavior of a simple Solow-Swan economy with Cobb-Douglas production function after unanticipated for changes in technology or population growth. The Solow model is solved here in aggregate, i. For that purpose, trending labor-augmenting technology and population processes are defined. Implements the deterministic optimal policy exercise in Figure 7.

DSGE Dynare Model Matlab Codes
A Short Course on. By Lawrence J. I will discuss the construction and use of dynamic stochastic general equilibrium DSGE models in the analysis of monetary policy. We review the solution and estimation of DSGE models.
