i applied to economics as well. my application was also sent to external peer review on 3/25 and i haven't heard anything either. someone i know that applied two years ago got his decision (recommended) end of may. someone else told me he got his rejection early may. yet another person didn't hear back at all - when she wrote to them in mid-july asking if a decision had ever been made, they told her that she had not been recommended, but didn't give her any reviews... all of these people applied to econ. so i guess i'm really not sure how this works
