“…To clean the raw data of TRACE, I use the code provided by Jens Dick-Nielsen on his website and follow Edwards, Harris, and Piwowar (2007) in addition to reach the full set of trade-volume weighted transaction prices (clean prices that exclude accrued interests) from July, 2002 to the end of year 2015. 45 With the clean prices of bond transactions, I locate month-end prices for each security, following Bai, Bali, and Wen (2018). In the processed TRACE sample, for each security at each quarter end, I keep the 8-digit CUSIP, quarter-end price, and the month-end prices for the next 12 months.…”
