Mathematical Economics

选课速读： ECON30020 不是“给经济学生补数学”的泛课，而是把抽象工具持续拉回经济学建模语境。墨尔本大学 handbook 明确写到这门课会把集合论、单变量与多变量微积分、约束优化、Kuhn-Tucker 条件、quadratic forms 和 eigenvalues/vectors 直接用于 firm theory、consumer demand、econometrics 与 market equilibrium 问题；评估则由两次 assignment、一次 mid-semester test 和带 hurdle 的期末考试组成。

Set theory, univariate calculus and optimisation are reviewed and applied to the theory of the firm and the theory of consumer demand. Linear algebra concepts including matrix operations, vector spaces and quadratic forms are introduced and applied to problems in economics and econometrics. Applications of multivariate calculus including constrained optimisation, the envelope theorem and Kuhn-Tucker conditions are covered.
