1. (?? points) Rupert’s CAPM testing
Rupert wants to test whether the CAPM model is a reasonable description of asset pricing behaviour.
(a) (3 points) What are the assumptions that underpin the Sharpe-Lintner (risk-free asset) version of
the Capital Asset Pricing Model?
(b) (2 points) Explain the Roll critique and its implications for empirical test of the Capital Asset
Pricing Model.
(c) (5 points) Explain the steps involved in using a cross-section regression to estimate the CAPM Se-
curity Market Line. Ensure that your explanation covers the steps required to address measurement
errors in CAPM Beta estimates and any selection bias issues associated with the methods used to
address measurement error in CAPM Beta estimation.
(d) (3 points) What would be the consequences if Rupert ignored measurement error in CAPM Beta
estimation when estimating the CAPM Security Market Line?
(e) (2 points) What would be the consequences if Rupert ignored selection bias when addressing the
measurement error in CAPM Beta estimates?
