Obtain the auxiliary values corresponding to each parameter, its size and its name
getx(con, varargin, Economies, FactorLabels, JLLinputs = NULL)
If con = 'concentration' and a parameter's name contains '@', then its auxiliary value is set to empty
variable inputs used in the optimization (see "optimization" function)
string-vector containing the names of the economies which are part of the economic system
list of necessary inputs for the estimation of JLL-based models (see JLL
function)
Necessary inputs for the estimation of the JLL-based models
This function is a modified version of the "getx" function by Le and Singleton (2018).
