1. rigorous proof-based course 在econ phd申請時是其中一個singal
real analysis可以說昰在calculus i-iii, linear algebra之後最常見的數學課之一, 要是這也叫"那么多数学", 可能可以省下一堆申請費(不太用申top的)
引用一下stanford的講法: "A large fraction of applicants demonstrate their skills in math by taking a non-introductory course in real analysis and receiving a high mark. " https://economics.stanford.edu/graduate/admissions
如果說stanford太高了, 那不如看看UCLA的: "Mathematical preparation is also essential. This should include a minimum of one year of Probability and Statistics and two years of Calculus. Additional coursework in mathematics and Statistics, especially Linear Algebra, Matrix Algebra, Advanced Probability Theory, Mathematical Statistics and Real Analysis, is highly recommended." https://economics.ucla.edu/graduate/prospective-students
