Risky steady state file given by MichelJuillard, error message

sfaf · March 10, 2019, 9:57pm

Dear Professor Johannes,

I am using examples and other files https://github.com/DynareTeam/dynare/tree/master/tests/risky_ss

I have installed MinGW64 Compiler.
But I am getting error give below:

Undefined function or variable ‘dr_np’.
Error in dyn_risky_steadystate_solver>risky_residuals_k_order (line 325)
gu1 = dr_np.ghu(i_fwrd_g,:);

Error in resol (line 144)
[dr,info] = stochastic_solvers(dr,check_flag,M,options,oo);
Error in stoch_simul (line 89)

Error in ex (line 222)
info = stoch_simul(var_list_);
Error in dynare (line 235)
evalin(‘base’,fname) ;

Please guide me on this.
Best Regards,
Shafi

Which of the mod-files did you run? Or do some of them work? And which Dynare version are you using?

Thanks, it is https://github.com/DynareTeam/dynare/blob/master/tests/risky_ss/example1_risky_3.mod.

and others with 3rd order perturbation give the same error.

Hello sfaf,

could you find a solution to the problem? I had the same issue when following the example provided Michell Juliard.

Best,
Ben

That is not an official feature and I don’t think it will work with order=3. @MichelJuillard Are there any plans of implementing this?

MichelJuillard · May 23, 2019, 1:20pm

At this stage there is no plan to implement it.

Thanks a lot for the fast reply. Does that indicate that it might work at order=2?

I just thought it is already implemented because in one of the example files that can be found here:

github.com

DynareTeam/dynare/blob/master/tests/risky_ss/example1_risky_3.mod

// Example 1 from Collard's guide to Dynare
var y, c, k, a, h, b;
varexo e, u;

parameters beta, rho, alpha, delta, theta, psi, tau;

alpha = 0.36;
rho   = 0.95;
tau   = 0.025;
beta  = 0.99;
delta = 0.025;
psi   = 0;
theta = 2.95;

phi   = 0.1;

model(use_dll);
c*theta*h^(1+psi)=(1-alpha)*y;
k = beta*(((exp(b)*c)/(exp(b(+1))*c(+1)))
    *(exp(b(+1))*alpha*y(+1)+(1-delta)*k));

This file has been truncated. show original

the final lines are

stoch_simul(order=2,irf=0);

options_.risky_steadystate = 1;
stoch_simul(order=3,irf=0);

Thanks for the clarification and all the insightfull replys in the forum.

Best,
Ben

The issue is with the k_order_solver, which is triggered if order>2. order=2 should work
