Dear all
I run code of cho et al (2020) working paper that uploaded in dynare site, but when code run, i receive following error:

Not enough input arguments.

Error in simult_ (line 37)
iter = size(ex_,1);

Error in sss (line 43)
y = simult_(temps,dr,ex1,iorder);

Error in calvo.driver (line 396)
oo_.stochastic_steady_state = sss(oo_.dr, irfburninlength, options_.order);

Error in dynare (line 281)
evalin(‘base’,[fname ‘.driver’]);

That file seems to only be compatible with an older Dynare version, i.e. 4.5.7. See
