ST222 Games, Decisions and Behaviour
Throughout the 202021 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and oncampus delivery through the year, and you should read the additional information linked on the right hand side of this page for details of how this will work for this module. The contact hours shown in the module information below are superseded by the additional information.You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.
ST22212 Games, Decisions and Behaviour
Introductory description
This module runs in Term 1 and is available for students on a course where it is a listed option and as an Unusual Option for students who have taken the prerequisites.
Prerequisites: ST115 Introduction to Probability OR ST111 Probability A.
Module aims
Throughout their history, game and decision theories have used ideas from mathematics and probability to help understand, explain and direct human behaviour.
Questions explored in the module include: What is probability? A set of axioms, a relative amount of outcomes, a belief? And how can this be elicited? What guides decisionmaking when outcomes are uncertain? What happens when information is only partial or ambiguous? What if there is more than one person, or how are decisions made in games? How do people perceive and evaluate probabilities and risks? Are they acting rationally or not? Which heuristics and biases come into play? Under which conditions do they occur, and how do they impact decisionmaking?
Answer will be embedded into theories and illustrated with practical examples from a wide range of applications including engineering, economics, finance, business, sciences, psychology and medicine.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
 Introduction and motivation
 Examples covering all parts of the module
 Some inspiring questions
 Overview
 Concepts of probability
 Axiomatic
 Propensity interpretation
 Frequentist interpretation
 Subjective probability
 Descriptive aspects of probability (empirically demonstrated aspects of perception of randomness and risk)
 Normative theory for decisionmaking under uncertainty and ambiguity
 Preferences
 Elicitation (with explicit examples who this can be done via interviews, expert opinions etc)
 Expected unitility theory
 Descriptive theory for decisionmaking under uncertainty and ambiguity
 Empirically demonstrated confirmation of and deviation from normative theory:
e.g. representativeness heuristic, anchoring, conjunction fallacy, availability heuristics, hindsight bias, ambiguity effect (Allais, Ellsberg paradox)  Models: prospect theory (Kahneman & Tversky), bounded rationality: the adaptive toolbox (Gigerenzer & Selten)
 Discussion: model comparison, feasibility of reduction of nonnormative behaviour through training
 Games
 Combinatorial games (winning strategy, examples, unsolved examples)
 Zerosum games (von Neumann's Minimax theorem, separability, domination, symmetry)
 Generalsum games (Nash equilibrium, evolutionary games, signaling and asymmetric information)
 Cooperative games (Shapley value)
Learning outcomes
By the end of the module, students should be able to:
 Describe the mathematical and philosophical basis for a number of alternative approaches to probability including subjective probability.
 Apply normative decision theory to model decision making in practical examples from a range of applications.
 Understand the foundations of and motivation for descriptive decision theory; describe and model deviations from normative theory in examples.
 Describe the elements of mathematical game theory, apply these to simple mathematical example games and suitable real world scenarios.
