hi,

I have a model that I compute steady states analytically.

my residuals almost are zero, but the model can not find steady states.

please help me.

It seems your model features a unit root in`M`

. In this case, there are infinitely many steady state and you typically cannot endogenously compute one of them. You need to provide one.

BUT I solve steady state analytically.I have two questions:

1)My analyticall steady state says that I have two steady state.when I provide one of them in dynare,it can not compute the steady state.

2)in my previous code that i upload,I use one of my steady states that i reach analytically for them.

how to fix this unit root problem?

please provide more detail that i know how to fix this problem???

thanks for your reply.

Given that your analytical steady state returns residuals, either your model equations or the steady state computations are wrong.

Because my steady states return sum of residuals zero,then it say my equations and steady states not wrong.

If its wrong,tell to me.and provide some mateials to fix this problem.

With very very thanks professor

Clearly, your residuals are not zero:
