Optimisation Techniques for Economists
Optimising decision behaviour is at the core of most economic analysis. Whether we ask how a consumer should behave, how firms should compete in a market or how governments should decide on their monetary policy, the ability to solve optimisation problems is key to finding an answer. This module provides a thorough introduction to the techniques involved in unconstrained and constrained optimisation. It expands on the optimisation techniques introduced in the microeconomics and macroeconomics courses in the first term and lays the foundation for many advanced economic option courses in the second term.
Additional Information: Internationalisation
Microeconomics is relevant across countries as it is based on mathematical models.
All of the resources for this module are available on the ELE (Exeter learning Environment).
This module equips students with logical thinking, numeracy and writing skills, as well as an understanding and theoretical knowledge of economic issues. These help students think like economists, a quality highly valued by employers.

Economic problems are often expressed using mathematical models which are to be formulated, analysed and to be confronted with real-world data. The module aims to make you familiar with those mathematical tools and methods which are used frequently in most economic models and to demonstrate how they are applied.
