“…In defence of the CAPM, Partington (2013) emphasises that the CAPM has clearly passed one very important test, that is, the test of time. Further to being the most preferred method in the valuation practice, it was decided to use the CAPM as a cost of equity estimate in this study for the following reasons: r no consensus exists, but various studies have found a positive association between the beta coefficient and the ex-ante cost of equity (Botosan 1997;Botosan and Plumlee 2002;Hail 2002); r as also previously argued by Hail (2002: 756), the purpose of this study is not to explain the absolute level of the cost of equity, but rather to examine the crosssectional variation in the cost of equity, conditional on the varying observed levels of IIR; r notwithstanding the critique against the CAPM, some empirical support for the CAPM is given by Da et al (2012) and the CAPM is often used to measure the cost of equity in emerging country studies (Collins and Abrahamson 2006;Hearn and Piesse 2015), as well as developed country studies where analyst forecast information was not available (Fu et al 2012); r thin-trading adjusted betas were used. According to Gopi (2016), the adjustment is done using the wellknown trade-to-trade adjustment procedure, as also described by Bradfield (2003); and r ex-ante estimate methods were considered not achievable in this study given the analyst forecast information (e.g., earnings per share projections) prerequisite.…”
