Economics emphasizes the importance of incentives and tradeoffs in choices, the strategic interaction of individual, households, firms, and governments, and the coordination of individual decisions through market mechanisms. The insights provided are relevant for decision-makers in industry, finance, government, and households themselves. Starting with the classic theory of consumer behaviour and market equilibrium, the module traces the role of incentives and its consequences for social welfare in a variety of economic situations, and explores extensions of the classical model.
This is a basic and applied theory course, but the content is applicable in every country. The examples used in this module can be applied to any firm or decision.
All of the resources for this module are available on the ELE (Exeter Learning Environment).

The aim of the module is to develop the basic tools for analysing problems of resource allocation used by economists working in research, government and business. The module deals with positive and normative problems. It seeks to include modern developments without being overly mathematical, and to develop a capacity to apply economic concepts to real-world problems.

We will first review basic economic concepts. Next, we will build and consider each element of the classical model of consumers and producers under perfect competition, gaining an intuitive and logical understanding of the assumptions and how the parts fit together. This leads to demand and supply curves, firms' entry and input/output, and households' consumption choices. We put this together to consider the theoretical ideal of an equilibrium and how well it 'works'.
We next relax some of the underlying assumptions of this model and see how this changes the outcomes. We introduce uncertainty (allowing us to consider key concepts from finance). We next consider three possibilities that can lead the unregulated market system to perform sub-optimally: asymmetric information, public goods, and market power (monopolies). We also consider how the harm from these 'market failures' can be reduced, including government policies and business innovations/tools.
Finally, we will learn about two modern extensions to the classical model. Game theory considers how people act when their best choice *may depend* on what others do; particularly relevant for small-group interactions such as international negotiations and competition between large firms. Behavioral economics relaxes classical assumptions such as unbounded cognition and willpower and pure self-interest, incorporating models and evidence from psychology such as loss-aversion, hyperbolic discounting, and concerns for fairness. We will consider the evidence for these models, particularly from lab and field experiments, and the implications for economic models and policy.
An indicative weekly plan is as follows:
Weeks 1-2: Economic basics
- 'Start thinking like an economist': Economic models and basic maths tools, introduction'
- 'How do economists think about choices?': Utility, preferences, indifference curves, budget constraints
Weeks 3-6: Building the model, putting it together, examining it
- Demand curves: Individual and market demand
- 'Who is making this stuff, and what are they putting in?': Production, costs, returns to scale, choice of inputs
- 'How do firms know how much to charge, and how much do they earn?': Profit maximisation and supply, perfect competition in a single market
- 'What are the outcomes of all this? Is this the best possible system?': Supply curves, entry/exit, CS and PS, tax incidence, general equilibrium and welfare (brief)
Weeks 7-8: ‘How the market can go wrong (and how to fix it)
- 'What if we don't know what will happen?': Uncertainty (basic concepts, EU, risk aversion, investment choices)
- 'What if some people know more than others?': Market failures -- Asymmetric information (brief)
- 'Who pays for the things we all benefit from?: Market failures -- Public goods
Weeks 9-10: ‘But what do real people do?' (extensions)
- 'How do we interact with others?': Game theory; experimental evidence on this
- Behavioral economics: limits to cognition, willpower, self-interest; applications and evidence
Week 11: Revision

The main source for this course is:
- (A special discounted edition of) "Intermediate Microeconomics and Its Application" (12th ed.), by Walter Nicholson and Christopher M. Snyder, Cengage Learning
- Earlier editions are also acceptable
- Note that any intermediate or advanced textbook in Microeconomics will cover virtually the same material, with varying degrees of mathematical rigour. There are now texts available for free, legally, online, such as “Introduction to Economic Analysis”, by Preston McAfee, Caltech and Tracy Lewis, Duke University, available at https://open.umn.edu/opentextbooks/BookDetail.aspx?bookId=47
