The Limits to Rationality in Economics Programme included two main events, in January 2009 and June 2009. Details of these events are provided below.
Limits to Rationality in Financial Markets: June 15th to July 3rd, 2009
The aim of this Workshop is to bring together mathematicians, philosophers, financial and economic modellers, practitioners in financial markets, neuroscientists, experimental psychologists, policymakers and economists interested in deploying insights from these other disciplines.
Overview
The standard efficient market models claim that trading in financial markets is driven by cognitive processes involving the maximisation of risk-adjusted returns, with arbitrage ensuring that the resulting prices are efficient in the sense of reflecting all the relevant available information, and the resulting return distributions following Gaussian statistics.
However, even the very language of financial markets, such as "bulls and bears", "market sentiment" and so on, suggests that affective processes play an important role. The observed return distributions exhibit fat tails, clustered
volatility, long-term memory and other features that can potentially result in financial crises damaging the economy as a whole (as is seen in the current "credit crunch'').
The challenges then are to construct tests for the presence of affective processes in the behaviour of agents in financial markets, analyse the interaction of such affective processes with cognitive processes, and model how the choices at the micro-level interact to produce the non-Gaussian statistics observed at the macro-level. In addition, there is a need to consider the effect of rational-but-perverse behaviour (due to poor incentivization) on the actions of individual agents and the system as a whole, to capture such effects in mathematical models, and minimize their occurrence in economic systems. Important policy implications are likely to to arise from such analyses, ranging from more effective regulation of financial institutions by central banks and other regulatory agencies, through to appropriate ways of financing public sector investment projects.
From a Scottish perspective, these issues are of key importance given the implications of the revisions of the Basel II regulations for the large Scottish financial sector, and the issues raised by the Scottish Futures Trust alternative to Public-Private Partnership schemes.
Workshop
This 3 week long workshop is designed to initiate a series of parallel research projects, facilitating interactions across traditional academic boundaries and involve practitioners and policy makers.
We considered the relevant areas in two day slots, leaving Wednesday of each week free for discussions. Each two-day workshop addressed specific questions which can be downloaded here. Download the full programme.
15-16 June: Philosophical Issues. Download a programme and abstracts here.

Encoding of the Past in Economic Agents and Institutions: January 7th-9th, 2009
(event advert, pdf 120k)
As well as a number of invited participants, the programme organisers welcome applications to attend and participate from those with an interest in this area (see below for details of how to apply).
This intrinsically multidisciplinary research area will be considered from the viewpoints of economics, mathematical modelling, neuroscience, psychology, philosophy of economics and financial markets, and public policy. The timetable will be more open-ended than is usual, to encourage informal interaction and discussion.
The following is a brief description of the intended discussion areas:
There is an increasing realisation that "memory effects" play a significant role in economics (both micro- and macro-) and in financial markets. Incorporating such effects into tractable models in a realistic manner raises many interesting questions that straddle the traditional academic boundaries. For example,
- What information about the past is relevant to economic decision making?
- What past experiences cannot be "unlearned" in view of subsequent developments?
- Is the representation of the past in any sense "rational"?
- Are affective as well as cognitive processes involved?
- Can the economic present rewrite the economic past?
- What are the implications of memory-dependence for modelling and policy-making?
