Accounting information quality in this paper is measured in two
perspectives: market-based and accounting-based perspective. Market-based perspective
views earnings as a reflection of economic income as representative of stock returns.
Many prior research measures the accounting information quality as the value relevance
of accounting information. They examine an earnings response coefficient (ERC) most
often short-term window, or the R2
from the earnings-return model, as the measure of the
investor responsiveness to earnings (Liu and Thomas, 2000; Holthaunsen and Watts,
2001). That is, how well of accounting information is used in valuing the securities
(Kothari, 2001; Barth, 2000). Theoretical based to return-earnings relationship is as
follows (Dechow et al., 2010).
