I don’t know know. But UPenn and Cornell’s websites explicitly state that coursework in mathematics is a main requirement. But I can tell you that I applied to one program straight out of undergrad and it was useless. The school expected me to complete 13 prerequisites; multivariablr calc, multivariable calc based statistics, grad level(ms) econometrics, upper div linear algebra, diff equations, and grad level finance course,,,, it was a financial economics PhD program. I was told by a Stanford professor finish ODE and if I can PDE.
the reason I mention this is because you didn’t state your whole profile. Also the school i applied to said I’d have to pay for the prerequisite courses and wouldn’t get funding until I passed all and taken off conditional status
