Consider the following model:  = 0 + 1 + 2 + Where VoterTurnout is the share of the population that votes, campaign expenditure is the total amount of campaign finance in the election, and age is the average age of the populace. Assume E(u|CampaignExpenditure, Age) = 0. Imagine that at low levels of campaign expense, there is low voter turnout. For each additional among of campaign expenditure, voter turnout increases by 1 on average. However, sometimes the campaign expenditure is not very successful and voter turnout remains low. Other times, the campaign expense is very successful and voter turnout is even more effective than average. Assume the sample size is not large (i.e., do not provide responses based on how each property changes as a function of increasing n). How does this affect:  

1. Biasedness of OLS estimators: 2. Variance of OLS estimators: 3. Efficiency of OLS estimators:
