Course Description: 

Mathematics is a language that allows us to communicate and think more clearly, often making it easier to solve problems. This is why modern economics uses the language of mathematics.

This course covers essential topics in mathematics used in intermediate and advanced economics and econometrics courses. This essential material can be learned in three or more mathematics courses, but those courses also cover numerous other topics that are of little use for economics.

Specifically, this course offers students concise coverage of three areas in mathematics and applied mathematics that we use extensively in mathematical and quantitative economics. The course content is split into three modules:

    • Linear algebra (weeks 1—5)
    • Calculus of several variables (weeks 6—10)
    • Optimization (weeks 11—15)

Assignments will include exercises in MATLAB (because there is little value today in doing much arithmetic or calculus by hand), while exams will test basic understanding of the mathematical content.

      • I selected MATLAB due to its relative ease of use for students without coding experience. Students who are comfortable using other software platforms may do so.

AI-Assisted Learning (Optional):

  • I am testing MATLAB Copilot Beta (native to the MATLAB IDE and hopefully in production by the time the Fall semester starts). I will encourage you to use it in homework assignments. 
      • If you are comfortable using other software platforms, you are also encouraged to use Github Copilot or other AI tools.

Textbook: 

  • Simon, Carl P., and Blume, Lawrence E. Mathematics for Economists. W.W. Norton, NY, 1994.

Financial Applications:

  • While the textbook covers a variety of economic applications, I will focus on financial applications, both to add coherence and to enhance immediate practical relevance for students who have already learned the math in other courses. Thus, the linear algebra module will focus on asset pricing, while the calculus and optimization modules will focus on risk-return preferences and portfolio selection.
