この論文の目的は、前期の利益情報を前提条件にして、当期利益の価値関連性(value relevance) を検証することである。第1 に、減益にはより多くのtransitory earnings が含まれており、減益企 業の報告利益にかかる係数は、増益企業よりも小さいが、その非対称性は環境条件にも規定され、 それが観察されない産業部門や期間もある。第2 に、大規模な利益変化額にはより多くの transitory earnings が含まれるという仮説(S 字型反応仮説)は棄却される。むしろ、大規模な増 益は小規模な増益よりもpersistent であり、大規模増益企業の報告利益(水準)にかかる係数は、 小規模増益企業の係数よりも大きくなるJ 字型の関係が観察される産業部門や期間も存在する。 第3 に、増益額と黒字額のrelevance は、前期が黒字か赤字かによって異なることもあり、また、 その影響の相違も、産業部門や期間などの条件に依存している。


The purpose of this paper is to investigate the value relevance of current year earnings with condition of previous year earnings. First, since negative changes in earnings may contain more transitory elements, the capitalization coefficient on earnings decrease is smaller. However, that asymmetry of coefficients is determined not only by the direction of earnings changes, but also by environmental conditions. The asymmetric effects are not observed in some industry sectors and periods. Second, we cannot detect the sufficient evidence supporting the hypothesis that current earnings would contain more transitory elements as the size of changes in earnings becomes larger, i.e. S shaped response hypothesis. On the contrary, the large size increase in earnings is more persistent than the smaller. In some industry sectors and periods, we find the evidence supporting the capitalization coefficient of earnings levels with larger positive changes is larger than the smaller, i.e. J shaped relationship between earnings and firm value. Third, the value relevance of earnings changes and levels differs among the sign of the previous year earnings. This effect of previous year earnings also depends on the environmental conditions of industries and years.
