#### Aims

- To describe the basic ingredients of decision theory, for individuals and for groups, and to apply the theory to a variety of interesting and important problems.

#### Content

- Introduction to decision analysis: utility.
- Uncertainty.
- Statistical decision theory: Bayes decisions.
- Bargaining.
- Game theory.
- Influence diagrams, group decisions and social choice.

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will: be able to solve novel and/or complex problems in Decision Theory.
- have a systematic and coherent understanding of theoretical mathematics in the field of Decision Theory.
- have acquired coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: Formulating decision problems and solving decision trees.
- Utility, value of money, multi-attribute utility.
- Use of data in decision making, statistical decision theory.
- Sequential decision making.
- Game theory, including two-person zero-sum games.
- Bargaining, including Nash' theory.
- Group decisions and social choice.

Subject-specific Skills:

- In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Modelling.

Key Skills:

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
- The end-of-year examination assesses the knowledge acquired and the ability to solve complex and specialised problems.
