Defined parameters

[Enthusiast]

Could defined parameters be a function of some endogenous variable?
Generally, according to my understanding defined parameters should be a function of other parameters. However, if I transformed a parameter to an endogenous variable, how should I define the other parameters?
So, the question is, is it possible to have an endogenous variable in the equations for some parameters?

Thanks a lot in advance

The answer is yes and no. Anything that is not time invariant is not a parameter. Thus, if a "parameter" depends on other variables, it will be time-varying and becomes a variable. All other "parameters" depending on this variable will also be variables.
But in general, there is no problem with replacing parameters by variables. You just need to define them as such.
