I want to put "et al." for citations with many authors more than two instead of full lists of authors. I know there are several similar questions to mine. But, all suggested solution have not worked in my case. I'm using roffin.cls, which is provided by Review of Finance, and jf.bst, which is also provided by Review of Finance. (http://www.oxfordjournals.org/our_journals/rof/for_authors/)
I constructed a simple sample code and attached it with .cls and .bst files. Please, let me know how to handle this problem. Thank you.
You can find the files in my Google drive folder: https://drive.google.com/folderview?id=0B4YZL9TZ6D20c3JLZzNLUHdQNkU&usp=sharing
