Penelitian ini bertujuan membuktikan pengaruh income smoothing terhadap earnings response coefficients dan pengaruh kualitas auditor sebagai variabel yang memoderasi hubungan income smoothing dengan earnings response coefficients. Hipotesis yang diajukan adalah : (1) Terdapat pengaruh income smoothing terhadap earnings response coefficients (2) Kualitas auditor mempengaruhi hubungan income smoothing dengan earnings response coefficients. Sampel penelitian sebanyak 69 perusahaan manufaktur yang terdaftar di Bursa Efek Jakarta dengan tahun laporan keuangan 1995-2003. Variabel yang diuji berupa variabel income smoothing yang diukur dengan Indeks Eckel, variabel earnings response coefficients yang diukur dengan slope regresi antara variabel Cumulative Abnormal Return dengan Unexpected Earnings, serta variabel kualitas auditor yang diproksikan dengan membedakan antara Kantor Akuntan Publik Big 4 dengan Non Big 4. Metode statistik yang digunakan adalah regresi berganda. Hasil penelitian menujukkan tidak terdapat pengaruh yang signifikan atas variabel income smoothing terhadap variabel earnings response coefficients ( 0,001813, t 1,565 dan p value 0,123) dan terdapat pengaruh variabel kualitas auditor terhadap hubungan variabel income smoothing dengan earnings response coefficients ( -0,074680, t –1,746 dan p value 0,0806).

This study aims at proving the influence of income smoothing on earnings response coefficients and the influence of auditor’s quality as moderating variable in the previous relation of income smoothing and earnings response coefficients. The proposed hypotheses are: (1) that income smoothing influences earnings response coefficients (2) auditor’s quality influences the relation of income smoothing and earnings response coefficients. The research samples are 69 manufacturing companies listed in The Jakarta Stock Exchange with their financial reports during 1995-2003. The tested variables are: income smoothing variable measured in Eckel Index, earnings response coefficients variable measured in slope regression between Cumulative Abnormal Return with Unexpected Earnings, and auditor’s quality which is proxied by dividing Big 4 and Non Big 4 public accountant offices. The statistic used method is double regression. The result shows that there is no significant influence of income smoothing variable on variable earnings response coefficients ( 0,001813, t 1,565 and p value 0,123) and there is influence of auditor’s quality on the relation of income smoothing and earnings response coefficients ( -0,074680, t –1,746 and p value 0,0806).
