We investigate two simple scenarios for explaining the observed Ly-a and rest-frame UV luminosity functions (LFs) of LAEs: (i) the \"escape fraction\" scenario, in which the \"effective\" escape fraction (including the IGM attenuation) of Ly-a photons is f_Lya ~0.1 (0.15) at z=3 (6), and (ii) the \"stochastic\" scenario, in which the fraction of LAEs that are turned on at z=3 (6) is \\Cstoc ~0.07 (0.2) after correcting for the IGM attenuation.
