group declaration for variables and shocks
@stepan-a, in the wiki you mentioned the possibility to add another keyword, like
group, similar to
long_name to be used in the declaration of variables.
Did you think/discuss about this in the dynare development?
Another possibility might also be a similar syntax as the equation tags, so that a variable might have different tags, using user-defined keywords for example
var y_us $y$ (long_name = 'GDP US') [group = 'real variables', country = 'US'] y_ea $y$ (long_name = 'GDP EA') [group = 'real variables', country = 'EA'] ...
what do you think?
