BSc Mathematics and Economics
About this course
Mathematics and economics are disciplines that are deeply intertwined in the modern world. Economics is fundamentally a mathematical science: the theories that explain how markets work, how prices are set, how macroeconomic systems behave, and how policy interventions affect outcomes are all expressed in the language of mathematics. Mathematics provides the formal tools, including calculus, linear algebra, probability, and optimisation theory, that allow economists to build rigorous models and derive precise predictions. Studying both together, in equal depth, is one of the most intellectually demanding and professionally rewarding combinations available at degree level. At the London School of Economics and Political Science, this three-year full-time BSc programme divides your time roughly equally between the two subjects, developing genuine expertise in both. Your mathematics studies will cover real analysis, linear algebra, probability theory, statistics, and mathematical methods, building the formal rigour that advanced economics demands. Your economics studies will engage you with microeconomic theory, macroeconomics, econometrics, and a range of applied and theoretical topics, developing your ability to use mathematical tools to analyse economic phenomena with precision. LSE's position as one of the world's leading social science institutions, with a faculty that includes some of the most prominent economists and mathematical social scientists in the world, gives the programme an academic environment that is difficult to replicate elsewhere. A year abroad is available within the programme. You will graduate with a combination of formal analytical precision and economic intuition that is among the most valued in quantitative professional careers. Graduates go on to careers in investment banking, economic consulting, central banking, financial analysis, data science, actuarial work, policy, and academia. Many pursue postgraduate study in economics, finance, or mathematics, and doctoral programmes in economics are particularly well-supported from this foundation.
