Consider the heterogeneous regression model
where 0i and 1i are random variables that differ from one observation to the next. Suppose that
are distributed independently of X i.
a. Let
denote the OLS estimator of 1 given in Equation (17.2). Show that
, where E ( 1 ) is the average value of 1 i in the population.
b. Suppose that
, where 0 and 1 are known positive constants. Let
denote the weighted least squares estimator. Does
