Steady state errors

Steady state

dear all:

how can i find steady state?many thanks! and why the Residuals of the static equations displayed twice?

2

The first display is the residuals given your initial values, the second one after steady state finding failed. The relevant one is the first

Equation number 1 : 0 : 1
Equation number 2 : 0 : 2
Equation number 3 : -0.017183 : r
Equation number 4 : 0 : 4
Equation number 5 : 0.00010529 : 5

There are two equations with residuals that cause the whole system to fail. Most likely there is still a mistake here that makes the model inconsistent with a steady state.

thanks,dear professor! I’ll do it right now.

dear professor,thanks for your advice,but another problem arises.
ERROR: There are 42 equations but 43 endogenous variables!

there are two categories of the firms in my codes,the wage(w1 w2)、output(y1、y2)、marginal cost(mc1、mc2) and capital(k1 k2）are different.Is this setting correct？

5

You had a model with the right number of equations. So check what changed relative to that one.

6

dear professor,I checked again and modified my codes but another problem airses.
Blanchard & Kahn conditions are not satisfied: no stable equilibrium

how can I do next?

Fix your timing.

exp(kbar(-1))=exp(u)*exp(k(-1));

cannot be correct. Capital services as a function of utilization are determined at time t, not t-1

thanks,professor.As you suggested,I fixed the time setting but still have a problem.
There are 13 eigenvalue(s) larger than 1 in modulus
for 12 forward-looking variable(s)

The rank condition ISN’T verified!

Your timing is still incorrect. Usually, it’s

exp(kbar)=exp(u)*exp(k(-1));

There may be other errors like this one.

11

wow,thanks a lot,dear professor!

12

I’m sorry to bother you again, professor.I have changed the codes about kbar、kbar1 and kbar2 but another problem arises.There are 11 eigenvalue(s) larger than 1 in modulus
for 12 forward-looking variable(s)

The rank condition ISN’T verified!

I really don’t know how to do,can you help me again?many thanks!
