[ZIP] My Matlab library contains common Matlab functions used by my other programs. Before using other programs, first download the library and then add a Matlab path to all the library files (including those in subdirectories).
[ZIP] The C/C++ and Dynare 4.2 code for the 2013 Econometrica paper "Land-Price Dynamics and Macroeconomic Fluctuations" by Liu, Wang, and Zha. For the C/C++code, click on C_Cpp_Library4LWZpaper.zip. For the Dynare 4.2 code, click on DynareCode4LWZpaper.zip.
[ASCII] The RWZ algorithm SRestrictRWZalg.m for implementing VAR sign restrictions of Canova, Faust, and Uhlig. The zipped file RWZrestrictions_FiscalPolicy.zip shows an empirical example of sign restrictions applied to identifying fiscal policy shocks. This new algorithm proves very efficient as compared to the existing algorithms and is coded up in Matlab. The algorithm is described in detail in the 2010 (April) Review of Economic Studies paper "Structural Vector Autoregressions: Theory of Identification and Algorithms for Inference" by Rubio, Waggoner, and Zha.
[ZIP] The Matlab code, fwzmsv_nk_example.zip (8KB), for the new-Keynesian example in the Journal of Economic and Dynamic Control paper "Minimal State Variable Solutions to Markov-switching Rational Expectations Models" by Farmer, Waggoner, and Zha.
[ZIP] The Matlab code for Conditional Forecasts in Dynamic Multivariate Models by Waggoner and Zha (Review of Economics and Statistics 1999). Click on Cfprob.zip (80KB) to download.
[ZIP] The Matlab code, GeneratingPriors.zip (6KB), for generating Normal, Beta, Gamma, and Inverse Gamma priors in the 2011 (2) Quantitative Economics paper "Sources of Macroeconomic Fluctuations: A Regime-Switching DSGE Approach" by Liu, Waggoner, and Zha. The file get_hyperpars2.m backs out the hyperp arameter values of the prior density to meet the specified probability interval with low and high values. You need 4 inputs: the low value, the cumulative probability at this low value, the high value, and the cumulative probability at this high value. In general, these probabilities are specified at 0.05 and 0.95. The zip file GeneratingPriors.zip contains other useful M files (see the readme_priors.prn file).
[ZIP] The Matlab code, LWZ_RED_PublicCode.zip, for the Review of Economic Dynamics paper "Asymmetric Expectation Effects of Regime Switches in Monetary Policy" by Liu, Waggoner, and Zha. Read the file readme_lwzmodel.txt for instructions of how to use this program.
[ZIP] The Matlab and C program, PublicCode_swzestimate.zip (4.8MB), for the Journal of Econometrics paper "Methods for Inference in Large Multiple-Equation Markov-Switching Models" by Sims, Waggoner, and Zha. Read the file Instructions_swz_estimate.prn for instructions of how to use this program. The executable files swzmsbvario.exe and swzestimate.exe are for Windows; the executable files swzmsbvario and swzestimate for Linux. If you wish to compile and link the C source files yourself, click on TZCcode.zip (562KB) to download the source code. You need a modern C++ complier, Intel MKL, and IMSL C library to compile. For compilation questions under the Windows or Linux operating system, please write to Eric Wang at Keyun.Wang@atl.frb.org.
[ZIP] The Matlab code for structural VARs with linear over-identified restrictions on both current and lagged coefficients discussed in Cushman and Zha (1997) and Zha (1999). This example, motivated by Dhawan and Jeske's DSGE model, uses the four variables: energy prices, durable investment, capital investment, and output. It is assumed that energy prices follow an exogenous autoregressive process. The code performs the three common tasks: (1) estimates the model parameters and impulse responses with or without the standard Bayesian prior, (2) computes the error bands for impulse responses, and (3) computes the marginal likelihood or data density. Click on readme_restrictedVAR.zip (34KB) to download the core files. Consult the file readme_mdd.prn for detailed explanations and instructions.
[ASCII] The C source code for Shocks and Government Beliefs: The Rise and Fall of American Inflation by Sargent, Williams, and Zha. To download this program, click on the files modeleconomy.c, modeleconomy.h, swz_comfuns.c, swz_comfuns.h, and probconst.c.
[ZIP] The Matlab code for estimating the Bayesian Vector Autoregressive (BVAR) models, just-identified and over-identified, with the Sims and Zha (IER, 1998)'s prior. Read the Word file Readme_BVAR.doc to see the instruction of how to use this code and click on AlphaModel_Files.zip (1.1MB) to download. The code was originally written by Zha and is extensively modified by Andy Bauer, a senior economic analyst, at the Federal Reserve Bank of Atlanta. The article by Robertson and Tallman is particularly useful for understanding the prior as well as various features of the model (e.g., the out-of-sample forecasts from this kind of BVAR model is insensitive to whether the data are of real time nature or in final revised form).
[ZIP] The Matlab code for computing the marginal likelihood or data density for structural BVAR models (including overidentified cases). Click on swz_mardd.zip (23KB) to download. Read the file readme_mdd.prn to see the instructions of how to use this code.
