Principal Aims

This module provides students with a thorough understanding in basic principles of microeconomics. You will be exposed to a range of the application theories. You will gain an understanding of consumer behaviour, production theory and how markets work, including strategic behaviour of firms and the various models under which firms might behave. You will gain skills and techniques to analyse problems from a mathematical, graphical and intuitive perspective applying your knowledge to real world scenarios.

Demonstrate an ability to apply their knowledge to important areas of application, including policy analysis.

Explain a variety of concepts using different approaches, including those involving mathematical, graphical and intuitive analysis.

Understand the way in which economic models are used to analyse problems and the limitations of them.

Construct models of both consumer and producer behaviour and understand their implications and limitations
