Financial estimates against investors’ preferences:anchoring, denial and spillover effects

This experimental study investigates how the characteristics of an estimate in a sensitivity disclosure and the level of threat it presents to investors' preferences interact to influence investors’ risk judgments. Firstly, I predict and find that variation in an estimate affects not only investors’ judgment on a related issue but also their future judgments on an unrelated issue. Secondly, I predict and find that investors are more sensitive to variations in an estimate when information contained in the estimate presents less threat to their preferred conclusions than when it presents greater threat. Finally, I predict and find that investors perceive more uncertainty regarding the association between the disclosed risk factor and the estimated financial reporting item in the estimate when the information presents greater threat

A complex systems approach to constructing better models for managing financial markets and the economy

We outline a vision for an ambitious program to understand the economy and financial markets as a complex evolving system of coupled networks of interacting agents. This is a completely different vision from that currently used in most economic models. This view implies new challenges and opportunities for policy and managing economic crises. The dynamics of such models inherently involve sudden and sometimes dramatic changes of state. Further, the tools and approaches we use emphasize the analysis of crises rather than of calm periods. In this they respond directly to the calls of Governors Bernanke and Trichet for new approaches to macroeconomic modelling.The publication of this work was partially supported by the European Union’s Seventh Framework Programme (FP7/2007-2013) under grant agreement No. 284709, a Coordination and Support Action in the Information and Communication Technologies activity area (‘FuturICT’ FET Flagship Pilot Project).
