Different expressions for same endogenous using scenarios
Posted: Thu Jul 13, 2017 12:17 pm
Hi all!
First of all, some general background:
I am building a model for simulation purposes in Eviews. The model is 100% theoretical in nature (it has not any observed data, it's all simulated within the model) and i'm trying to consider two different 'clousures' for the model. I have a "general" model and i'm using two scenarios, one for each clousure. In each scenario I have different expressions for the same endogenous variable.
Now, my specific question:
While I can specify the different expression for each scenario using the "modelname.drop & modelname.append" commands every time I have to switch from one scenario to the other, it would be great to have each scenario with it's specific equations stored, so I do not have to manually change them. I initially thought that the "modelname.override" command might do the trick, but the problem is that, depending on the clousure, i have the SAME endogenous in BOTH scenarios, but the equation that determine this endogenous is DIFERENT in each one. The ".override" doesn't work because the expression contains endogenous so I cannot build a "_alias" in the workfile prior to solving the model. ¿Has anyone know how to deal with this issue?
PS: The "drop+append" does the trick for the time being, but as it is a problem that I have with more than one variable it makes the program increasingly difficult to read.
