I'm a rising senior planning his schedule for next year, and I'm interested in pursuing a PhD in economics, specifically interested in studying labor economics and the economics of education as well as economic history. I was planning on taking a labor economics course this semester to A) gain more knowledge but also B) hopefully get some points for coursework for grad school. However, it's not offered next fall, so now I'm faced with two options:

1. take another ECON course in something else - probably information economics/game theory or development or something else
2. Don't take an econ elective this semester and cross my fingers that labor is offered next semester (I only have 1 econ elective left, since I'm taking two grad classes in place of my electives, there's a chance I may be able to squeeze another elective in though)

If I do either, im worried that grad schools will judge me for not taking any sort of coursework in the fields I'm interested in, but rather just in economics and economic theory (other than that 1 course, all my courses will be in theory or econometrics, all other field stuff I've learned has been as an RA or through reading literature, or through economic history courses). Do you think it's ok to take a different course, or should I wait to take labor, even though it won't be on my grad school applications? Thank you!
