% The approximated reduced form model is

|
%
|
|
% Y^*_t = Z Y_t [Measure]
|
|
% Y_t = A*Y_{t-1} + B*E_t [State]
|
|
%
|
|
% where Z is an p*m selection matrix (p<=m), Y^* is the p*1 vector of
|
|
% observable endogenous variables, Y is an m*1 vector of endogeneous
|
|
% variables, A is an m*m matrix, B is an m*r matrix (r<=m) and E an r*1
|
|
% vector of structural innovations.
|
|
%
|
|
% The contemporaneous is return impact (on the observables) of an innovation is
|
|
% given by F = Z*B. Matrix F is returned by this function.
