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.

Additional notes

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.
