“…Our study offers four important contributions. First, although prior studies have examined the effects of environmental disclosure on idiosyncratic risk (Lee and Faff, 2009;Salama et al, 2011;Oikonomou et al, 2012;Cai et al, 2016;Diemont et al, 2016;Utz, 2017;Linciano et al, 2018), we test the said relationship under the competing theories, and we shed light on the relevance of these theories. Second, in contrast to previous literature that uses the traditional capital asset pricing model, and on some occasions the Carhart four factor model (Mishra and Modi, 2013;Bouslah et al, 2013), we utilize both the four-and five-factor models to estimate idiosyncratic risk.…”
