BSc Economics

This course provides students with an intermediate level understanding of microeconomics through the development of theories that are at the core of neoclassical microeconomics and fundamental for the understanding and advancement of general, more sophisticated models for consumers and firms. A particular focus is on the notion of welfare in a basic competitive market economy where all agents have full information about the behaviours of other agents in the economy. To achieve that, a deep and concise understanding of the models of consumer choice and demand is required as well as a clear understanding of the decision processes of firms in the short run (decisions to produce or not) and the long run (decisions to enter a market or not). Finally, the unit addresses welfare issues such as the existence of equilibria, which are specific prices for goods at which consumers and produces act such that supply and demand in all markets of the economy are balanced. The properties of such equilibria and the corresponding allocation of goods are explored.

The aims of this unit are to: (i) provide students with rigorous understanding of the core neoclassical microeconomics involving consumers, producers, markets and notions of partial and general equilibrium.

At the end of this unit students should be able to: (i) demonstrate a clear understanding of preferences, choice, utility and demand; (ii) demonstrate a clear understanding of inputs, outputs, production, cost and supply; and (iii) demonstrate a clear understanding of perfect competition in a market, general equilibrium and welfare theorems.

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.

Tuition fees for home students commencing their studies in September 2027 will be £10,050 per annum. Tuition fees for international students will be £35,300 per annum.

For general information please see the undergraduate finance pages.

All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's Policy on additional costs incurred by students on undergraduate and postgraduate taught programmes (PDF document, 91KB).

We know that student finance can be complicated. The links below provide further information to help guide you.
