Consider the following panel model to examine the effect of retirement on consumption expenditure, consit, of individual i over years t=1,…,3: (B1) log(consit) = β0 + β1retiredit + β2ageit + β3marriedit + β4healthit + δ1Yr2t + δ2Yr3t + ai + uit Where: retiredit is a dummy variable equal to 1 if individual i is retired on year t and 0 otherwise ageit is the individual's age in years marriedit is an indicator variable for whether the individual is married (1) or not (0) in year t healthit is an indicator variable equal to 1 if the individual is in 'good health' and 0 otherwise Yr2 is a dummy variable equal to 1 in year t=2 and 0 otherwise Yr3 is a dummy variable equal to 1 in year t=3 and 0 otherwise Using the information above, answer the following 3 questions.

Question
Consider the following panel model to examine the effect of retirement on consumption expenditure, consit, of individual i over years t=1,…,3:
(B1) log(consit) = β0 + β1retiredit + β2ageit + β3marriedit + β4healthit + δ1Yr2t + δ2Yr3t + ai + uit
Where:
- retiredit is a dummy variable equal to 1 if individual i is retired on year t and 0 otherwise
- ageit is the individual's age in years
- marriedit is an indicator variable for whether the individual is married (1) or not (0) in year t
- healthit is an indicator variable equal to 1 if the individual is in 'good health' and 0 otherwise
- Yr2 is a dummy variable equal to 1 in year t=2 and 0 otherwise
- Yr3 is a dummy variable equal to 1 in year t=3 and 0 otherwise
Using the information above, answer the following 3 questions.
[i] Give two (2) examples of the kind of variables captured by the term ai in Model (B1).
[ii] What is the crucial assumption we must make so that the random effects (RE) estimator is consistent? Under this assumption, why is RE more preferred to pooled OLS?
[iii] Outline the key idea of the fixed effects (FE) transformation underlying the FE estimator. Why is this also called a 'within' estimator?
