% Declaration of the penalty as a persistent variable.
% Persistent variable 'penalty' is used to compute an endogenous penalty to
% the value 'fval' when various conditions are encountered. These conditions
% set also 'exit_flag' equal to 0 instead of 1. It is only when
% dsge_likelihood() is called by an optimizer called by
% dynare_estimation_1() that 'exit_flag' is ignored and penalized 'fval' is
% actually used.
% In that case, 'penalty' is properly initialized, at the very end of the
% present function, by a call to dsge_likelihood() made in
% initial_estimation_checks(). If a condition triggers exit_flag ==
% 0, initial_estimation_checks() triggers an error.
% In summary, an initial call to the present function, without triggering
% any condition, guarantees that 'penalty' is properly initialized when needed.
