Hello everybody,

I am relativly new with Dynare and so I am wondering wherther it is possible to use if functions (like in matlab) in Dynare.

e.g.:

if alpah\>=0.9;  
beta=0.2;  
else  
beta=0;  
end

I already checked the half forum but i could not find any subject relating to my question.  
Many thanks in advance for answering my question.

With best regards,

Hi,

yes it is possible to include into your mod-file the following directives:  
@#if  
@#else  
@#endif

see the Dynare macro language documentation
