(Or more technically, this analysis founpairwise tetrachoric correlations for three years among the six raters, with a mecorrelation of 0.30 (about 2 stanrviations). However, this also inclusome negative ones’ correlations, meaning whone rater founresponsible another foun‘irresponsible’.) A 2019 stu Gibson et al. shows a range of correlations. Yet another stu Berg et al. shows a range of correlations well: Berg looks a taset of ESG ratings from six fferent raters – namely, KL(MSStats), Sustainalytics, Vigeo Eiris (Moo’s), RobecoS(S P Global), Asset4 (Refinitiv) anMS– the correlations between the ratings are on average 0.54 anrange from 0.38 to 0.71.
