Bhattacharya (1979) proposed a hypothesis that states dividend can act as a powerful signal in order to solve information asymmetry problem. We measured information asymmetry by lack of earnings transparency. Therefore we examine the effect of earnings transparency on capital cost in two portfolios; the first with high dividend and the second with low dividend to test the above hypothesis. The results indicate that earnings transparency can only increase market component of expected return. In other words in the portfolio with low dividend signal there is a negative relation between earnings transparency and expected return (meaning that information asymmetry has not been solved). On the other hands in the portfolio with high dividend, the earnings transparency has no negative effect on capital cost; meaning that dividend signal solved information asymmetry problem</span> http://www.ijfma.ir/article_10271_1b5959f90b8e4966b8ea257c4352ebe9.pdf
