Steady ref
Reference to the steady-state level of a variable
Syntax
&variableName
&variableName{K}
Description
Use the &
sign in front of a variable name to create a
reference to that variable's steady-state level in transition or
measurement equations. Steady-state references may only be used in nonlinear models.
The steady-state reference can include a time shift (a lag or a lead),
K
. In that case, the steady-state value will be adjusted for
steady-state growth backward or forward accordingly.
The steady-state reference will be replaced:
-
with the variable itself at the time the model's steady state is being calculated, i.e. when calling the function
Model/steady
; -
with the actually assigned steady-state value at the time the model is being solved, i.e. when calling the function 'Model/solve''.
Examples
x = rho*x{-1} + (1-rho)*&x + epsilon_x !! x = 1;
