“…9 From equation(55), it is easy to see that if the market dividend growth is the only factor and if the sensitive coefficient has an unit measure of sensitivity, then the target payout ratio is identical to the aggregate payout ratio.10 If x, y and e represent general variables, and if y = a + bx + e, where COV(x, e) = 0, then COV(x, y) = COV(x, a + bx + e) = COV(x, x)b. Therefore: b = COV(x, y)/σ 2 (x).11 Recall that for the canonical CCAPM, aggregate dividend corresponds to aggregate consumption.12 Concerning the concept of long-run risk, see, again,Bansal and Yaron (2004),Bansal et al (2005),Hansen et al (2008),Bansal et al (2009),Bansal and Kiku (2011),Bansal and Shaliastovich (2013), orBergeron (2013).…”
