We construct a robust stochastic discount factor (SDF) that summarizes the joint explanatory power of a large number of cross-sectional stock return predictors. Our method achieves robust out-of-sample performance in this high-dimensional setting by imposing an economically motivated prior on SDF coefficients that shrinks the contributions of low ...

Across-sectional study is an observational study in which the exposure and the outcome are determined at the same time point for each study participant. Cross-sectional studies comprise the simplest individual-level observational study design and are usually relatively inexpensive and easy to conduct compared with case-control or cohort studies.
