Indeed, Economics programs tend to admit more students than Finance programs. However, what also matters is the research interest that you signal and the rigor and prestige of your current degree.
From my personal experience, some European universities might be more welcoming with candidates having no calculus courses on their transcripts. But the main reason why you should consider Europe is because most of the time, application is free in Europe, hence it doesn't hurt applying to more places.
You should also check out the placement record of the program and try to compare your background with someone who graduated from certain programs (look at the Job market candidates link) - in this way, you know more about your expected future after graduation as well as a rough guess of your chance to get admitted. The ultimate goal is never trying to get into a program at all cost, but to get into a program that gives you the job you want.
