Unit code ECON20071 10 Level 2 Semester 1 Economics Yes

### Overview

This unit provides students with the essential mathematical toolkit required by economics students. At the core of the unit are constrained, multivariate optimisation problems. Such problems form a core element of many economics units and students who took Advanced Mathematics will be familiar with the required solution techniques.
Students will also be introduced to the principles of modelling dynamic variables. Simple difference equations will be introduced to model the rate of change of variables.
Students will be provided with detailed material through lectures, tutorial, reading and online videos. A discussion board will allow students to receive frequent feedback on their understanding.

### Aims

The aim of this course is to introduce mathematical techniques useful in the economic and social sciences to those students who have the appropriate advanced mathematical background.

### Learning outcomes

The objectives of this course are that students will be able to:

1. Solve simple linear equations, find roots a quadratic and understand the solution to non-linear equations.
2. Understand functions, continuity and basic differentiation.
3. Solve one and two-variable unconstrained and constrained optimisation problems using the Lagrangian method.
4. Demonstrate their understanding of linear univariate difference equations.

### Syllabus

The preliminary syllabus is
•    Preliminaries and Pre-requisites. A review of your mathematical background and some observations on logic
•    Functions & Univariate Calculus. Functions, continuity. Roots of equations. Limits and basic differentiation. Stationary points and optimisation. Concavity and convexity.
•    Vectors and Matrices. An introduction to vectors and matrices: their mathematical manipulation - addition, multiplication. Inverse matrix. Determinants. Rank. Quadratic Forms.
•    Bivariate Functions
Surfaces in 3D, contours. Partial functions and partial differentiation: the Jacobian and Hessian. Optimisation; saddle points. Concavity/convexity. Finding maxima/minima of functions of two variables subject constraints; e.g., maximising utility subject to a budget constraint.

Ralf Becker Unit coordinator

For every 10 course unit credits we expect students to work for around 100 hours. This time generally includes any contact times (online or face to face, recorded and live), but also independent study, work for coursework, and group work. This amount is only a guidance and individual study time will vary
