SUR with system

[chungrak9]

Hello. In the data, there are 40 countries between 1950 and 2005.

I wonder if a SYSTEM object can replicate the results from a POOL object. The attached files show the POOL estimation setting.

In order to replicate the POOL estimation, I created a SYSTEM object, specified the following equations, and chose "Seemingly Unrelated Regression" with simultaneous updating, but the results were different from the POOL estimation.

d(AUS_dept) = c(1)*d(AUS_ind) + c(101) + c(201)*d(AUS_dept(-1))
d(AUT_dept) = c(1)*d(AUT_ind) + c(102) + c(202)*d(AUT_dept(-1))
d(BEL_dept) = c(1)*d(BEL_ind) + c(103) + c(203)*d(BEL_dept(-1))
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
d(VEN_dept) = c(1)*d(VEN_ind) + c(140) + c(240)*d(VEN_dept(-1))

Would you please let me know how to run the same model with a SYSTEM object?

Thank you very much!
