BSc Mathematics with Economics

Having a good grasp of mathematics is key to understanding modern economics. This BSc Mathematics with Economics gives you the chance to study both topics in depth.

The programme is carefully structured to focus on mathematical and statistical topics that are highly relevant to economics and finance. You’ll dive into key mathematical methods, such as algebra and calculus, and statistical theory. In parallel, you’ll study how these principles are applied in macroeconomics, microeconomics and mathematical economics.

This degree is taught jointly with our world-class Department of Economics. There is a strong focus on building your quantitative knowledge – increasingly important for a successful career in finance, accounting and other areas.

This degree will be of interest to all mathematically or scientifically minded students, regardless of whether you’ve studied economics previously.

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:

• L Alcock How to Study for a Mathematics Degree (Oxford University Press, 2013)
• R Allenby Numbers and Proofs (Butterworth-Heinemann, 1997)
• P Eccles An Introduction to Mathematical Reasoning (Cambridge University Press, 1997)
• T Gowers Mathematics: a very short introduction (Oxford University Press, 2002)
• M Liebeck A Concise Introduction to Pure Mathematics (Chapman & Hall/CRC Mathematics, 2005)

Applicants are encouraged to take the Test of Mathematics for University Admission (TMUA). The test is not mandatory, however a good performance on the test may make an application more competitive.

You’ll take six compulsory foundation courses and LSE100.

Your second year involves five compulsory courses in microeconomics, macroeconomics, further mathematical methods and real analysis.

You’ll also select optional courses, which may include an option from outside the department.

You’ll take options in advanced mathematical economics, mathematics, and statistics, along with one additional outside option.

The Department of Mathematics aims to be a leading centre for the study of mathematics in the social sciences.

The department has a vibrant intellectual community, with fantastic students, internationally respected academics and high-achieving alumni. Our department has grown rapidly in recent years, with exciting developments in research and new teaching programmes and courses.

This research encompasses four main overlapping areas:

• discrete mathematics
• mathematical game theory
• financial and related mathematics
• optimisation and algorithms.

All aspects of our research were ranked world-leading or internationally excellent in the most recent Research Excellence Framework (2021), submitted jointly with the Department of Statistics.

We embrace the School’s ethos of research-led teaching. Currently, we offer four undergraduate and three postgraduate programmes, as well as doctoral research opportunities on our MPhil/PhD in Mathematics. These programmes are all in high demand – attracting talented students from diverse backgrounds.

Our programmes are highly interdisciplinary and we have close ties with other departments at LSE, including Statistics, Economics, Finance, Management and the Data Science Institute.

Whatever your study route, you’ll benefit from a welcoming, inclusive and friendly learning environment where students and staff are supported to achieve their best.

Department of Mathematics

We consider each application carefully, taking into account all the details you’ve included on your UCAS form, such as:

• academic achievement, including predicted and achieved grades (also see specific information about this programme in the "entry requirements" above)
• subjects and subject combinations (also see specific information about this programme in the "entry requirements" above)
• your personal statement
• your teacher’s reference
• educational circumstances

We’re looking for students who demonstrate:

• a proportionate interest in mathematics and economics
• evidence of your understanding of the links between the two disciplines
• involvement in related extra-curricular activities, such as maths competitions or Olympiads
• the ability to think and work independently
• intellectual curiosity and the ability to ask incisive questions
• logical thinking and the ability to follow complex lines of reasoning
• creativity and flexibility in problem-solving
• great organisational and communication skills
• self-motivation and a willingness to work hard.

The 2027/28 tuition fee for Home students hasn’t yet been set. As a guide, the 2026/27 fee for Home students is £9,790. The Home undergraduate fee is charged in line with the maximum fee determined by the UK Government and may increase in subsequent years, in line with government plans.

The 2027/28 tuition fee for Overseas students is currently under review and will be set in the Summer of 2026. As a guide, the 2026/27 fee for Overseas students is £35,700 per year.

The Overseas student undergraduate fee may rise in line with inflation in subsequent years. Once announced, the Overseas tuition fee will remain at the same amount for each subsequent year of your full-time study regardless of the length of your programme. This information applies to new Overseas undergraduate entrants starting their studies from 2027 onwards.

Formative coursework

All taught courses include formative coursework, which is not assessed. This helps prepare you for summative assessment. We use a range of formative assessment methods, such as essays, case studies, reports, quizzes and mock exams.

Feedback is an essential part of the learning experience at the School. You’ll receive feedback on any formative coursework within three weeks, provided it’s submitted on time.

Summative assessment

This assessment counts towards your final course mark and degree award.

Summative assessment includes exams in most courses at the end of each year (May or early June). Some courses also include assessments in January.

You’ll receive feedback on any summative coursework as part of the assessment for individual courses (except for final submitted dissertations). Feedback will normally be provided before the examination period.

Please note that assessment on individual courses can change from year to year. See details of the current formative coursework and summative assessment for each course in the relevant course guide.
