We model the projected angular two-point correlation function (2PCF) ofobscured and unobscured quasars selected using the Wide-field Infrared SurveyExplorer (WISE), at a median redshift of $z \sim 1$ using a five-parameter HaloOccupation Distribution (HOD) parameterization, derived from a cosmologicalhydrodynamic simulation by Chatterjee et al. The HOD parameterization waspreviously used to model the 2PCF of optically selected quasars and X-raybright active galactic nuclei (AGN) at $z \sim 1$. The current work shows thata single HOD parameterization can be used to model the population of differentkinds of AGN in dark matter halos suggesting the universality of therelationship between AGN and their host dark matter halos. Our results showthat the median halo mass of central quasar hosts increases from opticallyselected ($4.1^{+0.3}_{-0.4} \times 10^{12} \; h^{-1} \; {M_{sun}}$) andinfra-red (IR) bright unobscured populations ($6.3^{+6.2}_{-2.3} \times 10^{12}\; h^{-1} \; {M_{sun}}$) to obscured quasars ($10.0^{+2.6}_{-3.7} \times10^{12} \; h^{-1} \; {M_{sun}}$), signifying an increase in the degree ofclustering. The projected satellite fractions also increase from opticallybright to obscured quasars and tend to disfavor a simple `orientation only'theory of active galactic nuclei unification. Our results also show that futuremeasurements of the small-scale clustering of obscured quasars can constraincurrent theories of galaxy evolution where quasars evolve from an IR- brightobscured phase to the optically bright unobscured phase.
