Behavioural Biases in Investor Decisions

2016
Ex post examination of investor behaviour and tests of market prices against theoretical predictions reveal numerous anomalies and puzzles. Despite the large catalogue, most biases can be attributed to a few factors: Simplification of the decision process Reliance on past values Status quo bias that avoids excessive reaction ...

Is optimism optimal? Functional causes of apparent behavioural biases

Behavioural Processes, 2012
We review the use of the terms 'optimism' and 'pessimism' to characterize particular types of behaviour in non-human animals. Animals can certainly behave as though they are optimistic or pessimistic with respect to specific motivations, as documented by an extensive range of examples in the literature.

Decision Making, Belief and Behavioural Biases

SSRN Electronic Journal, 2019
Behavioural finance theories explain "why" individuals exhibit behaviours that do not maximize expected utility. Behavioural finance highlights inefficiencies, such as under- or over-reactions to information, as causes of market trends and, in extreme cases, of bubbles and crashes.

Biased diffusion in percolation systems: indication of multifractal behaviour

Journal of Physics A: Mathematical and General, 1987
The authors study diffusion in percolation systems at criticality in the presence of a constant bias field E. Using the exact enumeration method they show that the mean displacement of a random walker varies as (r(t)) approximately log t/A(E) where A/(E)=In((1+E)/(1-E)) for small E. More generally, diffusion on a given configuration is characterised by

Biased Diffusion in Chainlike Fractal Structures: Universal Behaviour

Europhysics Letters (EPL), 1988
We study diffusion on topologically linear fractal structures under the influence of a uniform external field. Due to the fractal nature of the chain, the uniform field acts on a random walker like random correlated (local) fields in a one-dimensional chain.

Behavioural Biases and the Pricing-Kernel Puzzle

SSRN Electronic Journal, 2017
The pricing-kernel, when estimated from index options, appears to show risk-loving behaviour for small gains and losses. Although this puzzle could be caused by option buyers using subjective probability-weighting, such weighting generates an unrealistically large (and time-varying) risk-premium.

Behavioural Biases in Financial Decision-Making

SSRN Electronic Journal, 2016
Behavioral finance is an emerging field of study which is relatively new and having its provenance from decision theory. Behavioral finance is a multidisciplinary research area that combines psychology and finance and investigates the issues that impact the decision-making process and explains the irrational nature of individuals, groups and ...

Information biases and behaviour in asset markets

This thesis conducts a comprehensive analysis of the behaviour and biases of information intermediaries in asset markets, focusing on analysts and media. The first empirical chapter examines analysts’ herding behaviours in stock recommendation revisions. The findings suggest that foreign analysts typically exhibit a higher herding tendency than
