Morning. Please I have a problem when I try to execute my mode file with my data file, this error message appears. please what can I do to solve it?  
thanks.

Dynare is case-sensitive. Your model variables are lowercase, while your datafile uses uppercase names.

thanks very much I have rectified it but another problem is there. I do not understand, when I execute the simlation, its run. But when I try to estimate, the following error message appears:

Error using ==\> print\_info at 40  
Blanchard Kahn conditions are not satisfied: no stable equilibrium

Error in ==\> initial\_estimation\_checks at 69  
print\_info(info, DynareOptions.noprint)

Error in ==\> dynare\_estimation\_1 at 169  
oo\_ =  
initial\_estimation\_checks(objective\_function,xparam1,dataset\_,M\_,estim\_params\_,options\_,bayestopt\_,oo\_);

Error in ==\> dynare\_estimation at 70  
dynare\_estimation\_1(var\_list,dname);

Error in ==\> darline at 265  
dynare\_estimation(var\_list\_);

Error in ==\> dynare at 120  
evalin(‘base’,fname) ;

I don’t realy know what to do.  
Thanks in advance

You should then provide your calibrated values as explicit starting values. Moreover, given your unit roots (two eigenvalues are 1) you might need the diffuse\_filter option in estimation (see the manual)

Some writers make it difficult to understand the point they’re trying to get across. You, the other hand have made your points clear, concise and interesting.
