We focus on the latter and investigate the dependence of their fraction on redshift. We also examine the dependence of the radio-loud fraction (RLF) on BH mass (MBH) and Eddington ratio ({lambda}_Edd_), while excluding the redshift bias by narrowing its range. In both of these investigations, we remove the bias associated with: (1) the diversity of source selection by constructing two well-defined, homogeneous samples of quasars (first within 0.7<=z<=1.9, second within 0.5<=zw=0.7); and (2) a strong drop in the RLF of quasars at smaller BH masses by choosing those with BH masses larger than 10^8.5^M_{sun}_. We confirm some of the previous results showing the increase in the fraction of radio-loud quasars with cosmic time and that this trend can be even steeper if we account for the bias introduced by the dependence of the RLF on BH mass, whereas the bias introduced by the dependence of the RLF on Eddington ratio is shown to be negligible. Assuming that quasar activities are triggered by galaxy mergers, we argue that such an increase can result from the slower drop with cosmic time of mixed mergers than of wet mergers.2021ApJ...922..202Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/922/202CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)VII/286 : SDSS quasar catalog, fourteenth data release (Paris+, 2018)VII/289 : SDSS quasar catalog, sixteenth data release (DR16Q) (Lyke+, 2020)J/ApJS/95/1 : Atlas of Quasar Energy Distributions (Elvis+ 1994)J/AJ/131/666 : Double-lobed radio quasars from the SDSS (de Vries+, 2006)J/ApJS/166/470 : SDSS-Spitzer type I QSOs IR photometry (Richards+, 2006)J/ApJ/658/815 : Radio loudness of active galactic nuclei (Sikora+, 2007)J/MNRAS/405/2302 : Improved redshifts for SDSS quasar spectra (Hewett+, 2010)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/A+A/544/A25 : GPS radio sources multifrequency study (Mingaliev+, 2012)J/ApJ/765/62 : SDSS-DR7 opt. sp. analysis of radio galaxies (Sikora+, 2013)J/ApJ/769/79 : Spitzer obs. of radio-loud AGNs (CARLA) (Wylezalek+, 2013)J/MNRAS/462/1910 : H-ATLAS NGP LOFAR radio catalogue (Hardcastle+, 2016)J/ApJS/228/9 : Physical param. of ~300000 SDSS-DR12 QSOs (Kozlowski, 2017)J/ApJS/233/17 : Swift/BAT AGN spectroscopic survey.
