Week 7: Modelling Framing Effects

Guest speaker: Natalie Gold (Philosophy Department, King's College London)

Required reading:

*Gold, Natalie and List, Christian (2004) Framing as path dependence. Economics and philosophy, 20 (2). pp. 253-277.

Further reading:

If you're not familiar with framing effects and prospect theory then they should read either

Kahneman, D.; Tversky, A. (1979). "Prospect theory: An analysis of decisions under risk". Econometrica 47: 313–327.

or

Tversky, A.; Kahneman, D. (1981). "The Framing of decisions and the psychology of choice". Science 211 (4481): 453–458.

Natural discussion topics are how to model framing and the rationality of framing effects. Frederic Schick has interesting material on both these topics. Most of it is in his books but there are a couple of articles and students might read one of them:

Frederic Schick (1992). Allowing for Understandings. Journal of Philosophy 89 (1):30-41.

or

Frederic Schick (1987). Rationality: A Third Dimension. Economics and Philosophy 3 (01):49-.

For those super-interested in rationality, John Broome's discussion of the Allais Paradox and the independence axiom in his "Weighing Goods" would be relevant (it's actually about the correct level of description). Those super-interested in modelling framing could read something on Michael Bacharach's Variable Frame Theory, either:

Bacharach, Michael and Bernasconi, Michele (1997) 'The Variable Frame Theory of Focal Points: An Experimental Study', Games and Economic Behaviour, 19(1), April, pp. 1-45.

or

Bacharach, Michael (1993) 'Variable Universe Games', in Binmore, Ken, Kirman, Alan and Tani, Piero (eds.) Frontiers of Game Theory (Cambridge, MA: The M. I. T. Press), pp. 255-275.

$$ The readings are in descending order of importance (and, obviously, the suggestion is that people only read one of each disjuntion).

LIZ'S TALK:

Identifying the enemy: Competing or complementary theoretical approaches in decision making research?

Abstract. Describing decision making as resulting from an adaptive toolbox of ‘fast and frugal’ heuristics has radically changed the field of decision making research, and created a lot of controversy. One of the major ways that the ‘fast and frugal’ (F&F) approach has changed the field has been to shift it away from attempting to provide a single domain general model of decision making towards identifying and describing different heuristics and the environments in which they are used. This shift also involves a move away from ‘as-if’ models of decision making towards ‘process’ models that attempt to describe how people actually make decisions. However, domain general models need not be psychologically implausible, and F&F models are not necessarily psychologically plausible themselves. Given this, I will question whether domain general and F&F models should really be seen as true enemies. It will be argued that in meeting the challenges of providing an methodologically and theoretically adequate account of decision making, the F&F account will likely end up being fairly similar to a domain general account. Similarly, it will be suggested that developing contemporary domain general accounts (e.g. evidence accumulator models, parallel constraint satisfaction models) is likely to use similar research techniques to those found in the F&F approach. In this case, following the domain general or F&F approach may not make much difference in the models eventually produced. However, there are pragmatic, practice-based advantages with both theoretical approaches, as they focus research on different aspects of decision making. As such, it is suggested that both approaches are useful ones to develop, thus providing a nice illustration of theoretical pluralism in action.
