Equity risk premium - which Risk free to use?

CFA Level II Equities
#1

Is the general use to use long term RF for CAPM, Macroeconomic models, build up but …

short term RF for Fama French and APT portfolio models?

Kaplan notes are not explicit on this . Thanks in advance

#2

Always use Long-Term riskfree rate except Fama and Pastor. Just remember that.

Everything else use Long-Term

#3

I’ve got a Kaplan exam question - exam 1 afternoon q 109- that uses T-Bill rate rather than 10 year treasury for risk free in APT model! Thanks
