st: Simulation question.
I have a simulation problem.
Usually, what I've seen done in simulations is to change
values in independent variables and see their result on the
(predicted dependent variable).
reg GDP pop invest
replace pop =pop * 1.03 /* 3% growth of
g diff = gdphat - gdphat2 /*Measure of the
impact of the population growth */
Now, here is my question:
Suppose I want to double my GDP ?
I am interested in how my independent variables will change (in their
coeffcients and/or in their observations ???)
to meet the new values of GDP.
I guess I am facing a constraint problem but do not know how to do this in
How can I do that?
