BSc Mathematics and/with Economics

Overview of the two degrees 

Mathematics is essential for an understanding of modern economics. A degree combining these two strongly related disciplines gives you the opportunity to study both economics and mathematics in depth and enables you to acquire the technical aptitude and analytical skills to proceed to a successful career in finance, business and many other fields. Although specific techniques may go out of date, the ability to think analytically is something that remains with you for the rest of your life, enabling you to adapt to new developments in your chosen career. Both our degrees are carefully structured so that the mathematical and statistical topics you study are those of greatest relevance to economics and finance.

Recent graduates have gone on to work in the areas of corporate finance, accountancy, management, and banking. Many have pursued graduate study in areas related to mathematics, economics, or both.

Features of the two programmes

The Department of Mathematics at LSE is internationally renowned for its teaching and research in mathematics related to the social sciences, particularly the mathematics necessary for understanding economics. Both our degrees are taught jointly with LSE's world class Economics Department and enable you to build a strong quantitative knowledge base - increasingly important for a successful career in economics and finance. This degree will be of interest if you have a mathematical/scientific background, regardless of whether you have previously studied economics.

BSc Mathematics and Economics is a joint degree programme where students study roughly equal amounts of both subjects over their three years. BSc Mathematics with Economics has mathematics as its major subject and economics as its minor subject, and study of mathematics will make up approximately 75 per cent of the degree. Both degrees have exactly the same first year courses and, subject to satisfactory progress, students are able tp move between these two degrees in their second year.

Graduates will be able to combine a good understanding of modern economics with a high degree of mathematical expertise. This combination is an excellent foundation for careers in many walks of life.

Degree structure

The degrees involve studying 12 courses over three years, plus LSE100. A course outline for BSc Mathematics and Economics can be found here, and for BSc Mathematics with Economics here.

Teaching and assessment

You will usually attend two lectures and one related class for each course per week (eight lectures and four classes). In addition you will work on exercises in your own time. These are then discussed in the weekly classes of 15 students. You will have an academic adviser who will be available to offer general guidance and advice on your studies, and you will be expected to meet him or her at least twice a term.

The main exam period is in May/June, although some courses have exams in January.

Preliminary reading

For an introduction to mathematics as it is applied in economics and finance, we recommend:

  • M Anthony and N Biggs: Mathematics for Economics and Finance (Cambridge University Press, 1996)

If you wish to gain further insight into what economists study we suggest that you first look at the following popular book:

  • T Harford: The Undercover Economist (Oxford University Press, 2006)

Much of university level mathematics is concerned with formal proofs and rigorous mathematical argument, and this is necessary for some of the advanced mathematics required in finance, economics, and other fields of application. For an introduction, we recommend: 

  • T Gowers: Mathematics: a very short introduction (Oxford University Press, 2002)
  • M Liebeck: A Concise Introduction to Pure Mathematics (Chapman & Hall/CRC Mathematics, 2005)
  • P Eccles: An Introduction to Mathematical Reasoning (Cambridge University Press, 1997)
  • R Allenby: Numbers and Proofs (Butterworth-Heinemann, 1997)
