What major to choose for UCSD: econ vs management science vs international business

Hi, I am currently a California Community College student and I am planning to apply to UC this year. I am interested in both business&econ(however I think business degree will be better since it is more practical than econ?)
First I thought majoring in econ (+management minor) would be good(and I believe that UCSD is known for econ?)
But International Business is also appealing to me since it actually has various business courses in its curriculum(but since this major is in international studies department, I have to take some courses that are not related to business/econ).
I am also considering Management Science, the major that is focusing on business analytics(I am also interested to this subject & I think it has good job prospect?).
Which major will help me the most to learn about business and which of them have the greatest job prospect? (I will take Management or econ minor no matter what my major will be)
If UCSD have undergrad business admin major, I would’ve chosen that, but they do not have it, so… What will be my best choice??? :slight_smile: I check all the curriculum but still I cannot decide what major should I apply…!!
