  It has been observed that the yields of strange and multi-strange hadrons
relative to pion increase significantly with the event charged-particle
multiplicity. We notice from experimental data that yield ratios between
non-strange hadrons, like p/$\pi$ or hadrons of same strange content, like
$\Lambda$/K$_s^0$, show similar enhancement. We have studied this behavior
within the ambit of a parton model (EPOS3) and A Multi-Phase Transport (AMPT)
model in pp and p-Pb collisions at LHC energies. We investigate model
predictions of yields and yield ratios of different identified hadron
productions as a function of charged-particle multiplicity and compare them
with published ALICE results. The string melting versions of AMPT and EPOS are
found to establish enhancements in the particle yield ratios.
