Abstract: 本稿では、韓国におけるK-IFRSの強制適用が情報の非対称性に与える影響について分析している。分析の結果、K-IFRS強制適用の前後において韓国企業の情報の非対称性が平均的に有意に低下したことが発見されている。また、本稿の追加分析ではK-IFRS強制適用の効果が上場中小企業により強く現れることも発見されている。このような結果は、IFRS強制適用の場合にも上場中小企業に情報環境の改善によるベネフィットがもたらされうることを示唆するHan et al. (2016)やHamberg et al. (2013)と整合的である。, Using firms listed on Korean Stock Exchange and Korea Securities Dealers Automated Quotations as primary sample, this study examines the effects of mandatory K-IFRS adoption on information asymmetry. My results are as follows. First, the information asymmetry of Korean firms is reduced on average by the mandatory adoption of K-IFRS. Second, this information asymmetry reducing effect of mandatory K-IFRS adoption is more pronounced for listed small and medium-sized companies. These results are consistent with studies suggesting that mandatory IFRS adoption improves firms’ information environment and this effect also accrues to listed small-and medium-sized companies (Han et al.2016; Hamberg et al. 2013).
