Module

Advanced Mathematics for Economists

Module description

Summary:

This module is aimed at students who are considering a Masters and/or PhD in Economics. The module will cover a range of relevant mathematical tools and techniques that are typically required for further study in economics; the aim is to deepen and extend the mathematical preparation of 3rd year undergraduates by exposing them to rigorous higher level mathematics and providing them with the opportunity to develop proofs and apply new mathematical tools. Knowledge of elementary matrix theory and calculus is assumed.

The level of rigor will vary. Parts 1  and 2 will aim for thoroughness rather than for covering a huge range of material. Students should develop a feel for when a proof is complete and rigorous and when arguments are missing. In Part 3, emphasis is placed on learning how to quickly understand mathematical tools and be able to apply them, rather than on theoretical formalism. This is achieved sometimes at the expense of rigor. Where proofs are beyond the level of this course, references are given.

 

Additional Information:

Internationalisation
Mathematics is a global language, so the technical skills students acquire in this module can be used internationally.

Employability
By solving statistical mathematical problems and exercises, students are equipped with practical problem-solving skills, theoretical skills, and an understanding of mathematical relationships. All of these are highly valuable to employers.

Sustainability
All of the resources for this module are available on the ELE (Exeter Learning Environment).

Syllabus plan

This is an indicative outline. Further details will be available in week 1 of the module

Part 1 (3 weeks)

  • Numbers
  • Sets
  • Proofs and mathematical logic

In Part 1 we will provide the basics for the following material. The important properties of numbers and how they are described axiomatically (in particular, their order structure and completeness) will be discussed. Central notions of set theory will be developed and illustrated. Important methods of proofs (indirect proof, inductive proof) are illustrated in examples.

 

Part 2 (2 weeks)

  • Set-theoretic Topology
  • Fixed Points
  • Sequences: Definition of Sequence and Subsequence, Bolzano-Weierstrass Theorem and Cauchy criterion
  • Limits and Continuity: Definition of Continuity and Uniform Continuity, Intermediate Value, Differentiation

In Part 2 we will give a rigorous introduction to basic topological concepts (limit points, neighbourhoods, compact spaces, metric spaces etc.) and provide many examples of topological spaces. The emphasis is on teaching how to do rigorous proofs using abstract concepts.

 

Part 3 (5 weeks)

  • Ordinary differential equations
  • Eigenvectors and Eigenvalues
  •  First order differential equations systems:
  • Other applications of mathematics to economics, such as discrete math and combinatorics.

In Part 4 we will introduce the most elementary notions of first and second differential equations. We will subsequently study systems of linear differential equations, their solutions in the various cases, stability conditions, phase diagrams and some economic applications. For this part only elementary matrix theory and basic calculus are needed.
