Equity risk premium - which Risk free to use?

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

Yes, short term for FF and pastor. Long term otherwise. Harrogath explained it well here: http://www.analystforum.com/forums/cfa-forums/cfa-level-ii-forum/91349370.
