Monte Carlo Simulations in Econometrics
Q: In a Monte Carlo simulation, if we double the sample size n while keeping the same X values and error variance, the variance of b₂ will:

Unbiasedness requires only the first four SLR assumptions (linearity, random sampling, zero conditional mean, and variation in x). The full CLM assumptions (which add homoskedasticity and normality) are needed for the exact finite-sample distributions and efficiency properties.
