This course is designed for first-year Economics Ph.D. students, and can be used, as one of the core courses, to satisfy the graduation requirements of the MEcon Programme. Students are expected to be proficient in calculus, matrix algebra, and econometrics at the undergraduate level (i.e., ECON0701/ECON2280).
