If there is no cross-equation correlation of the error terms in a simultaneous equations system, what is the best way to estimate the parameters
Homework Answers
If there is no cross-equation correlation of the error terms in a simultaneous equations system then best way to estimate the parameters is Limited information maximum likelihood method.
Because this method each equation in the system is considered separately, and the estimator does not account for any cross-equation error correlation that may exist.

serial correlation happens when: There is high correlation between the consequent error terms of the regression. There is high correlation between two or more of the independent variables. There is high correlation between some of the independent variables and the error terms. There is high correlation between the dependent variable and the error terms.
