Impossible to find the steady state. please give me a help!

when I use my mod code , I get some errors as follows:
Error using print_info (line 74)
Impossible to find the steady state. Either the model doesn’t have a steady state, there are an infinity of steady states, or the guess
values are too far from the solution

Error in stoch_simul (line 98)
print_info(info, options_.noprint, options_);

Error in inb1 (line 294)
info = stoch_simul(var_list_);

Error in dynare (line 180)
evalin(‘base’,fname) ;

please give me some suggestions, or correct my mod code!

Thanks !

You should focus on the exogenous processes and whether they are consistent with the model.

exp(b) = exp((a(-1))^rhoB)*exp(epsB); exp(g) = exp((g(-1))^rhoG)*exp(epsG);
look weird. Usually, you have something along the lines of

exp(g) = exp(g(-1))^rhoG*exp(epsG);
with g being 0 in steady state.
