The rigor for econ here is nowhere near that of math/physics. Econ is the most popular major here with like ~300ish students each year. In general, I would not say econ is rigorous...but it really depends on you. You may find it either easy or challenging.
As a comparison, for math/physics, you'll have a hard time finding a math/physics major saying it's NOT rigorous, no matter how good they are. If you were wondering whether this kind of statement can be said for econ, the answer is no.
"Do the students pull all-nighters on a regular basis ??"
No. Sure there are some who do it, but that is because they choose to do so. This is a pretty hard place, but so is other colleges that are as prestigious as Princeton. However, it's not like you'll be worked to death with no sleep on a regular basis. It is not too bad if you develop a good work ethic, or if you're just extremely smart
How's the surrounding town ??
