Hi, I am looking for papers on international trade that use a trimmed and staggered dataset for staggered DID estimation. Most of the papers I have read use a full panel, for example, monthly trade flow data for all countries from 1994 to 1999. However, my research is RTA-related. There are several RTAs worldwide, and I am considering trimming the trade flow data using the date of each RTA's establishment as the event window 0 point. For example, there are two RTAs: one between Korea and Brazil in January 2001 and another between the US and Canada in January 2006. I would trim the global trade data from January 2000 to January 2002 and from January 2005 to January 2007, then combine them to create my research dataset. Unfortunately, I cannot find any papers that use the same method for data compilation. Could anyone please let me know if they are aware of any papers that research international economics and compile the "staggered" data I am thinking of? Papers from other fields would also be fine, as long as they use this type of data compilation! Thank you.
