3. Real Business Cycle Model

3.1 Lecture:

• First set of lecture notes

• code for the first model we did in the class: optimal growth model,

• code for the growth model with labor: optimal growth model with labor leisure choice,

• stochastic growth model,

• RBC model with balanced growth path,

• important reading King and Rebelo (2000): "Resuscitating Real Business Cycles",

• King Plosser Rebelo (2001): ".Production, Growth and Business Cycles: Technical Appendix"

• code for RBC model with balanced growth path

• Calibration - updated slides, paper by Cooley 1997, Calibrated Models

• model evaluation + observation equation based on Pfeifer lecture notes

• slides

• code to solve the King Rebelo 1999 by:

• method of undetermined coefficients

• QZ decomposition (using solab.m function)

• dynare in levels

• dynare log-lin solution

4. Performance of RBC model

4.1 Model Evaluation

• Model evaluation in my slides, underlying paper for the discussion is here, lecture by Chris Sims see here

• see critique by Galí (1999) of RBC models, some evidence and discussion on monetary policy neutrality Gali textbook ch.1

• for summary on what we know about shocks driving the cycle see Ramey 2016

  • • clean dynare output function

    • this code shows how to use Kalman filter to extract shocks from the observable series (watch Kalman filter explained in an extremely intuitive way, see Pfeifer lecture notes on how to link observables with your model variables), and it also demonstrates one way how to run loops in dynare, you will also need this .mod file, this is the code for King Rebelo 99 when frish elasticity is different from one

• Problem set 5 (Criticism of RBC), due 1.12.2017

• Solution, ExpKingRebeloMIII.mod file, code to get TFP innovations using Kalman filter

4.2 Beyond Calibration

• my slides, baseline model

• Estimating baseline model using GMM, Ruge Murcia (2011) for the Handbook of Empirical Macroeconomics

• DSGE VAR code

• Bayesian Estimation code

5. Classical Monetary Model

• • • 4.1 Lecture: slides, Gali chapter 2, dynare code, hand solution code

    • 4.2 Seminar: Model evaluations

      • Problem set 6, due 15.1.2017

      • Solution
