Another study that used job applicants as a sample was conducted by Rafaeli, Hadomi, and
Simons (2005). It involved a plant located in Israel and focused on three recruitment methods:
employee referrals, geographically focused ads (i.e., the local newspaper), and geographically
unfocused ads (i.e., a national newspaper). They found that referrals generated more applicants,
more hires, and a higher yield ratio (hires/applicants) than geographically focused ads, which, in
turn, outperformed unfocused ads on these three criteria.
