“…Measurement is therefore a question of the best possible approximation. Many studies consider the quantity of disclosure a good approximate measurement of the quality (Horngren, 1957;Robb, 1980;Dye, 1985;Barron et al, 1998;Penman, 2003;Barth et al, 2003;Bushman and Smith, 2003;Mensah et al, 2006). On the other hand, there are those who, while admitting that there is a relation between quantity and quality, do not accept that the first is a correct approximation of the second, and maintain that quality depends also on other factors such as the "richness" of the contents (Beattie et al, 2004;Beretta and Bozzolan, 2008).…”
