In this contribution, the production of heavy-flavor hadrons as a function of multiplicity, via the study of the D-meson and heavy-flavor hadron decay leptons self-normalized yields in pp collisions at the center of mass energy √(s) = 13 TeV is discussed. Comparisons are made with similar measurements of J/ψ at √(s) = 13 TeV and various model calculations. The \mathrmΛc+/D0 and \mathrmD+s/D0 yield ratios in different multiplicity intervals in pp collisions at √(s) = 13 TeV are also reported. In addition, the ALICE measurement of \mathrmΛc+ production in p-Pb collisions at √s_\rmNN = 5.02 TeV down to transverse momentum (p\rm T) = 0 GeV/c is presented. Finally, the nuclear modification factor is shown for open charm hadrons at √(s) = 5.02 TeV in p-Pb collisions. Finally, measurements of the elliptic flow of heavy-flavor hadron decay leptons in p-Pb systems are presented, which hint towards a possible collective behaviour in high multiplicity p-Pb collisions.
