We employ two risk adjusted methods of calculating bond abnormal returns which summarize by Bessembinder et al.(2009). We select a control sample from Moody’s Peer Group to compare with 13D sample. We employ generalized sign test introduced by Cowan(1992) to avoid stringent assumption about return distributions under parametric tests, The empirical results of this study show that significant negative abnormal bond returns were discovered during 13D event periods.1130437 bytesapplication/pdf論文公開時間: 2026/12/31論文使用權限: 同意有償授權(權利金給回饋本人)Schedule 13D併購公司債利差M&AYield Spreadthesis10.6342/NTU201600878http://ntur.lib.ntu.edu.tw/bitstream/246246/274139/1/ntu-105-R03723061-1.pdf
