May 16, 2016 · Hello, I am writing to ask how the code Prof. I believe there is nothing wrong with the model because when do a stochastic simulation, with stoch_simul, there are no errors. 1. Third-order approximation 4. The models solved by Dynare include those relying on the rational expectations hypothesis, wherein agents form their expectations about the future in a way consistent with the model. Apr 16, 2009 · I tried to simulate the deterministic three sector model as given in Acemoglu chapter 20 which is based on Kongsamut Rebelo and Xie (2001) however all I get is NaN s except the initial value and the last observation (where the last observation equals to the initial value). 0. 2. There is a timing convention in Dynare that lets Dynare know when something is a predeter-mined state variable. 7 Initial and terminal conditions Another one is to study, how an economy, starting from arbitrary initial conditions at time 0 converges toward equilibrium. Dynare uses a Newton-type method to solve the simultaneous equation system. the error message tells : “Warning: Matrix is singular to working precision. Mar 16, 2017 · To work around this issue, I log-linearized model by hand and used that for the deterministic simulation and it works fine for temporary shocks. 05; first_time = 1; for i=1:length (rhos) … Write the Dynare code to perform a stochastic simulation of this model for 2000 periods and generate impulse response functions for the endogenous variables for 60 periods. Hence, typing \stoch simul(periods=300);" will produce moments based on a simulation with 200 variables. When I use stoch_simul(periods=0,irf=0,order=1) I got for every variable in my model their theoretical moments. Second-order approximation 4. 05:1. But when I use a simulation of the model by setting stoch_simul(periods=1000,irf=0,order=1) some of my variables’ moments display NaN. Model_Diagnostics detects no obvious problems with the mod file, and the B-K . For e. First-order approximation 4. Stochastic solution and simulation (Dynare Reference Manual) More precisely, stoch_simul computes a Taylor approximation of the decision and transition functions for the model. Nevertheless, we a try to do a deterministic simulation, with simul, a get the following message: Simulation terminated with NaN or Inf in the residuals or endogenous Jul 29, 2019 · The deterministic simulation of the model give a solution. 12. Due to the design of Dynare, in Jul 17, 2014 · I am using dynare to solve a simple RBC model with recursive preferences. In particular, Dynare requires that predetermined variables (like the capital stock) show up as dated t − 1 in the time t equations and t in the t + 1 equations. g. PROBLEM: when running the simulation, I Jun 11, 2017 · 4. State variables: xt = [x1t, x2t, , xnt]0 The endogenous variable can be expressed as yt = ̄y + a (xt ̄x) Jun 11, 2017 · Dynare Reference Manual: 4. Perfect foresight 4. I know I could use the initval and endval command right after the model block, but my model is complicated that I want to For deterministic simulations, Dynare uses a Newton{type algorithm, rst proposed by La argue (1990), instead of a rst order technique like the one proposed by Fair and Taylor (1983), and used in earlier generation simulation programs. But Dynare is Nov 10, 2014 · Dear All, I need your help. 4. initval; @#include "steady_state1. For simul, you should start with 100 or 200 periods and check whether convergence back to stready state happens any earlier. We believe this approach to be in general both faster and more robust. 13. Nov 3, 2013 · I want to simulate in a deterministic model, but the result is nan or constant numbers, I just simplify the model of Iacoviello(2005) removing housing sector, and I check the model many times, could anyone help me, many thanks!

Pfeifer posted here Loop over parameters for looping over a parameter value in a stochastic simulation, e. Stochastic solution and simulation 4. Using this, it computes impulse response functions and various descriptive statistics (moments, variance decomposition, correlation and autocorrelation coefficients). For deterministic simulations, the numerical problem consists of solving a nonlinear system of simultaneous equations in n endogenous variables in T periods. 12 Deterministic simulation When the framework is deterministic, Dynare can be used for models with the assumption of perfect foresight. Why? Greetings, Daniel Jul 31, 2018 · I have a model, building on Ghironi and Melitz (2005) where the stochastic simulation solve with no issues, and produces sensible responses, but with the deterministic simulation, no matter how many periods I try to simulate over (I’ve tried up to 20000), the results do not converge with any size of shock >0. In this case models, the command histval permits to specify different historical initial values for variables with lags for the periods before the beginning of the simulation. The mod file is attached. For deterministic simulations, the numerical problem consists of solving a nonlinar system of simultaneous equations in n endogenous variables in T periods. g rhos = 0. By default, Dynare drops the rst 100 values from a simulation, so you need to give it a number of periods greater than 100 for this to work. But, i cannot do stochastic simulation. : "dynare *. To run a Dynare le, simply type "dynare lename" into the command window while in Matlab. 3. I need to compute the perfect-foresight transition path (deterministic simulation) between an initial steady state and a final one. 6.
