Two-pass cross sectional regression (TPCSR) is frequently used in estimating factor risk premiums. Recent papers argue that the common practice of grouping assets into portfolios to reduce the errors-in-variables (EIV) problem leads to loss of efficiency and masks potential deviations from asset...

We evaluate the performance of various methods for estimating factor returns in an approximate factor model. Differences across estimators are most pronounced when there is cross-sectional heteroskedasticity, or when cross-sectional sample sizes, n, are below 4,000 assets. Estimators...

Abstract We propose estimators of the stochastic discount factor (SDF) using large cross-sections of individual stocks. Our small-sample bias corrections allow us to exploit unbalanced panels of individual stock returns. Our estimators can accommodate prespecified traded and non-traded factors,...
