Autumn Module

Principal Aims

To develop the requisite quantitative skills for a rigorous study of contemporary economics. The module forms part of the first year core cluster EC120 Quantitative Techniques, which is made up of one module in Mathematical Techniques (A (EC121) or B (EC123)), one module in Statistical Techniques (A (EC122) or B (EC124)) as well as Computing and Data Analysis (EC125).

Principal Learning Outcomes

By the end of this module you should know the main mathematical ideas and techniques routinely used for economic analysis.


Prerequisite. You will be expected to have a good knowledge of A level algebra and calculus including the rules of differentiation and integration (which will not be taught).

The module will typically cover the following topics:

Calculus of functions of two or more variables; Unconstrained and constrained optimisation; Comparative statics; Matrix algebra; Difference equations; Applications of all techniques in economics.
