Since people have started asking, I figured I should say something on the subject of last names--specifically, what mine is now. So here it is, broken out into two easy-to-read (translation: lazy) bullet points:
1) Legally, my name stays the same. I will use that name for all work-related activities, including publication.
2) In all other contexts, I am going by Ross's last name.
I don't have some deep reason for that choice. Basically, it came from piecing together the following three facts (note the bullet points):
1)I have a really really common last name (shared with over 30% of the US population) whereas Ross's name is much less common
2)Having two different names can be inconvenient, especially with kids
3)My name is better professionally, both because I've already published under it, and also because it falls near the front of the alphabet (author order in econ is almost always alphabetical)
I may choose to change the legal aspect eventually, depending on whether it is more irritating to go by a name that is not my legal one socially or professionally. Either way, the outward appearance will remain the same.
