정보이용자관점의 원칙중심회계–금융위원회의 회계감독지침이 회계정보의 시장반응에 미치는 영향

This study examined how investors evaluate the accounting guidelines of supervisory authorities from the perspective of information users. Specifically, this study analyzed how the stock returns of those companies changed on the date of publication of the accounting supervisory guidelines announced in 2018. And this study examined the change in value relevance for R&D expenditures around the issuance of accounting guidelines. As a result, the cumulative abnormal return of pharmaceutical and bio companies was significantly positive around the supervisory guidance announcement date. In particular, the greater the proportion of capitalized development costs among R&D expenditures, the greater the market response, which means that investors are positively evaluating the announcement of supervisory guidelines. However, it was found that the value relevance or earnings response coefficient(ERC) for R&D expenditures was not different from before the supervision guidelines were issued. The results show that accounting guidance can reduce of the uncertainty about accounting processing and accounting supervision risks, however it does not significantly improve the usefulness of accounting information. The contribution of this study is to provide empirical evidence of whether accounting guideline enhances the value relevance of accounting information, and to suggest the policy direction about the regulators’ accounting guidance.
