QUESTION 8
A true economic model is defined as
Y=P,+P,X+P,Z+u
where X and Z are postively correlated.
If we instead estimate the model
Y=8,+8,X+e
What can we say about the OLS estimator of 8, as an estimator of B.
6, is an unbiased estimator of B.
6, is a biased estimator of B.
61 is an upwardly biased estimator of B,
6, is an downward biased estimator of B.
