Sets the seed used for random number generation.
For all parameters, endogenous and exogenous variables, stores their value in a text file, using a simple name/value associative table.
Note that no variable type is stored in the file, so that the values
can be reloaded with load_params_and_steady_state
in a setup where
the variable types are different.
The typical usage of this function is to compute the steady-state of a model by calibrating the steady-state value of some endogenous variables (which implies that some parameters must be endogeneized during the steady-state computation).
You would then write a first ‘.mod’ file which computes the
steady state and saves the result of the computation at the end of the
file, using save_params_and_steady_state
.
In a second file designed to perform the actual simulations, you would
use load_params_and_steady_state
just after your variable
declarations, in order to load the steady state previously computed
(including the parameters which had been endogeneized during the
steady state computation).
The need for two separate ‘.mod’ files arises from the fact that
the variable declarations differ between the files for steady state
calibration and for simulation (the set of endogenous and parameters
differ between the two); this leads to different var
and
parameters
statements.
Also note that you can take advantage of the @#include
directive to share the model equations between the two files
(see section Macro-processing language).
For all parameters, endogenous and exogenous variables, loads
their value from a file created with save_params_and_steady_state
.
This function is used in conjunction with
save_params_and_steady_state
; see the documentation of that
function for more information.
