In this part of the course we begin discussion of
decision theory (this week) game theory (next week).
We will eventually relate these to philosophical issues and
about individual and joint action.
This lecture depends on you having studied some sections from a previous lecture:
For the minimum course of study, consider only these sections:
Alternatively, if you have more time but not enough for everything,
skip Dual Process Theory Opposes Decision Theory? and study the
There is a bit more than usual to cover this week, which will be hard if
this is your first encounter with decision theory.
Ask a Question
Your question will normally be answered in the question
session of the next lecture.

: I use ‘decision theory’ for the theory elaborated by Jeffrey (1983). Variants are variously called ‘expected utility theory’ (Hargreaves-Heap & Varoufakis, 2004), ‘revealed preference theory’ (Sen, 1973) and ‘the theory of rational choice’ (Sugden, 1991). As the differences between variants are not important for our purposes, the term can be used for any of core formal parts of the standard approaches based on Ramsey (1931) and Savage (1972).
: This term is used for any version of the theory based on the ideas of Neumann et al. (1953) and presented in any of the standard textbooks including. Hargreaves-Heap & Varoufakis (2004); Osborne & Rubinstein (1994); Tadelis (2013); Rasmusen (2007).
