Sample Question
In a lagged dependent variable model, the dependent variable from the previous period appears as a regressor. Which of the following best describes the primary challenge this creates?

The lagged dependent variable is always multicollinear with other regressors

OLS estimates become biased and inconsistent if serial correlation is present

The model violates the assumption of homoscedasticity

Prediction intervals become wider than in standard models

Sample Question
A distributed lag model allows the effect of an independent variable to be spread over multiple time periods. What is the primary advantage of using lagged variables in econometric analysis?

They eliminate multicollinearity between variables

They capture delayed economic responses and dynamic relationships

They reduce the number of observations required

They guarantee statistical significance of coefficients
