The Psychology of Risk: The Behavioral Finance Perspective by Victor Ricciardi :: SSRN

The Psychology of Risk: The Behavioral Finance Perspective by Victor Ricciardi :: SSRN | Bounded Rationality and Beyond | Scoop.it
HANDBOOK OF FINANCE: VOLUME 2: INVESTMENT MANAGEMENT AND FINANCIAL MANAGEMENT, Frank J. Fabozzi, ed., John Wiley & Sons, pp. 85-111, 2008 

Abstract:      
Since the mid-1970s, hundreds of academic studies have been conducted in risk perception-oriented research within the social sciences (e.g., nonfinancial areas) across various branches of learning. The academic foundation pertaining to the "psychological aspects" of risk perception studies in behavioral finance, accounting, and economics developed from the earlier works on risky behaviors and hazardous activities. This research on risky and hazardous situations was based on studies performed at Decision Research (an organization founded in 1976 by Paul Slovic) on risk perception documenting specific behavioral risk characteristics from psychology that can be applied within a financial and investment decision-making context. A notable theme within the risk perception literature is how an investor processes information and the various behavioral finance theories and issues that might influence a person's perception of risk within the judgment process. The different behavioral finance theories and concepts that influence an individual's perception of risk for different types of financial services and investment products are heuristics, overconfidence, prospect theory, loss aversion, representativeness, framing, anchoring, familiarity bias, perceived control, expert knowledge, affect (feelings), and worry.

The Precautionary Principle: Fragility and Black Swans from Policy Actions

The Precautionary Principle: Fragility and Black Swans from Policy Actions | Bounded Rationality and Beyond | Scoop.it

Abstract—The precautionary principle (PP) states that if

an action or policy has a suspected risk of causing severe

harm to the public domain (affecting general health or the

environment globally), the action should not be taken in the

absence of scientific near-certainty about its safety. Under

these conditions, the burden of proof about absence of harm

falls on those proposing an action, not those opposing it. PP

is intended to deal with uncertainty and risk in cases where

the absence of evidence and the incompleteness of scientific

knowledge carries profound implications and in the presence of

risks of "black swans", unforeseen and unforeseable events of

extreme consequence. Here we formalize PP, placing it within

the statistical and probabilistic structure of “ruin” problems, in

which a system is at risk of total failure, and in place of risk we

use a formal"fragility" based approach. In these problems, what

appear to be small and reasonable risks accumulate inevitably

to certain irreversible harm. Traditional cost-benefit analyses,

which seek to quantitatively weigh outcomes to determine

the best policy option, do not apply, as outcomes may have

infinite costs. Even high-benefit, high-probability outcomes

do not outweigh the existence of low probability, infinite cost

options—i.e. ruin. Uncertainties result in sensitivity analyses

that are not mathematically well behaved. The PP is increasingly

relevant due to man-made dependencies that propagate impacts

of policies across the globe. In contrast, absent humanity

the biosphere engages in natural experiments due to random

variations with only local impacts. Our analysis makes clear that

the PP is essential for a limited set of contexts and can be used

to justify a limited set of actions. We discuss the implications

for nuclear energy and GMOs. GMOs represent a public risk of

global harm, while harm from nuclear energy is comparatively

limited and better characterized. PP should be used to prescribe

severe limits on GMOs.

A Reinforcement Learning Mechanism Responsible for the Valuation of Free Choice

A Reinforcement Learning Mechanism Responsible for the Valuation of Free Choice | Bounded Rationality and Beyond | Scoop.it
Summary

Humans exhibit a preference for options they have freely chosen over equally valued options they have not; however, the neural mechanism that drives this bias and its functional significance have yet to be identified. Here, we propose a model in which choice biases arise due to amplified positive reward prediction errors associated with free choice. Using a novel variant of a probabilistic learning task, we show that choice biases are selective to options that are predominantly associated with positive outcomes. A polymorphism in DARPP-32, a gene linked to dopaminergic striatal plasticity and individual differences in reinforcement learning, was found to predict the effect of choice as a function of value. We propose that these choice biases are the behavioral byproduct of a credit assignment mechanism responsible for ensuring the effective delivery of dopaminergic reinforcement learning signals broadcast to the striatum.

Time Teasers: Structured Procrastination

Time Teasers: Structured Procrastination | Bounded Rationality and Beyond | Scoop.it
Image credit: Dan Kleinan

A recent article in the New York Times highlighting the oft-overlooked
malady of “precrastination” gives us an opportunity to discuss some of the
downsides of our own intuitions in relation to existing time management
systems.

As the article points out, “people appear to be wired to incur a
significant physical cost to eliminate a mental burden.” When applied to
time management, this often results in what Dan Ariely refers to as
“structured procrastination”.

Structured procrastination involves getting little, relatively
insignificant things done, in an attempt to “eliminate a mental burden” --
in this case the burden of having many things on your plate. With a
standard to-do list, we have a long list of potential activities that vie
for our time, and we need to pick and choose which of all these things to
take care of first. Not surprisingly, this leads to us checking off those
things that are quick and easy to finish (and thus give us the joy of
checking them off quicker), as opposed to the things that are difficult but
also likely to be important.

On top of the drive to attend first to the small things (and maybe never
getting to the large ones), we also generally waste a great deal of time on
the maintenance of small tasks -- just writing them down and then ticking
them off of our to-do lists.  This is of course a fantastic way to feel
productive, but it mostly results in putting off the things that we should
really be focusing on: the looming project, the awkward phone call, the
term paper.

Getting mentally demanding tasks done requires solidifying our commitment
to these tasks. Research suggests that simply scheduling things leads to a
much higher rate of completion, which is why we developed Timeful’s smart
suggestions. We think having a proactive calendar that reminds us about
truly important tasks is crucial to developing the behavior that will curb
precrastination and procrastination both.


Here’s Dan on the problem of structured procrastination:

RELEARNING ECONOMICS: The Post-Crash Economics Society (PCES) have produced a compelling analysis of the failings in economics education and set out a road map for reform. 

“This report addresses a real need, for a more pluralistic and varied approach to the economics curriculum at university level. The mainline of economics from Adam Smith onwards is diverse and often departs from the current mainstream and the way that the subject is taught needs to recognise this. I welcome this contribution to discussion about the way we should explore the living tradition of economic thought and the light it casts on the contemporary world.”

Dr Stephen Davies, Education Director at the Institute of Economic Affairs.

This is a very important Report by the Post-Crash Economics Society. They explore the existing curriculum in careful detail, displaying the narrow theoretical monoculture which characterises not only Manchester’s curriculum but most economics degree courses in the UK and, indeed, the world. They outline what they think the curriculum should be: a programme geared to the problems of the actual economy through history, using the diversity of analyses that have developed through the years. The Report is a landmark: scrupulous, well-informed, passionate, it is required reading for every head of an economics department and highly recommended for everyone interested in the future of economics.

Victoria Chick, Emeritus Professor of Economics at University College London and co-founder of the Post-Keynesian Economics Study Group.

The fight to reform Econ 101

The fight to reform Econ 101 | Bounded Rationality and Beyond | Scoop.it

During the last weekend of June, hundreds of students, university lecturers, professors and interested members of the public descended on the halls of University College London to attend the Rethinking Economics conference. They all shared a similar belief: that economics education in most universities had become narrow, insular and detached from the real world.

For a brief period after the financial crisis of 2008, the shortcomings of the economics profession and the way it is taught were recognized. Many economists offered up mea culpas of various kinds and conceded that since they did not foresee the biggest economic event since the Great Depression, there was probably something seriously wrong with the discipline. But as time passed and many economies began to experience gradual, somewhat muted recoveries, the profession regained its confidence.

When I was completing my master’s degree at Kingston University last year, I experienced this firsthand from the more mainstream faculty there. Lecturers offered potted explanations of the crisis using old analytical tools such as supply and demand graphs that cannot incorporate expectations to explain asset price bubbles. The same economists who, just a few years ago, told us that financial markets were the conduits of perfect information began to introduce doublethink phrases in the media such as “rational bubble” (in which investors allegedly act irrationally by bidding up asset prices in full knowledge that prices are heavily inflated but think they can bail out of the market before prices fall) to explain the events of the past few years. There is nothing rational about investors’ acting this way, because they cannot know when the bubble will burst and so cannot time their exit from the market. They cannot know when the herd movement that they are part of will come to an end, so any action that they take to ride the wave will be just as irrational as those of people unaware of the bubble. The entire exercise appeared to be an ad hoc attempt to reinterpret the facts to fit the pet theory — economic agents aware of relevant information act rationally — rather than to alter the theory in light of the facts.

It was difficult not to sense the Soviet-style revisionism that had occurred within the halls of learning: The party had tossed history down the memory hole and introduced a strange, seemingly self-contradictory language that they were busy foisting upon an unwitting public. One Chicago school economist, Ray Ball, argues that the now notorious efficient market hypothesis (EMH), which states that financial markets price in all relevant information, is actually supported by the recent crisis. He argues that the capital flight that led to the bank meltdowns lends support to the EMH because it shows how rapidly financial markets react to new information. But as many will remember, investigations clearly showed that information was not being processed efficiently by market participants in the run-up to the crisis. The most colorful example of this was the Standard & Poor’s employee who, responding to a colleague who said that they should not be rating a mortgage-backed security deal because the estimations of risk were incorrect, said that cows could be estimating the risk of a product and S&P would still rate it.

Nobel Laureate Robert Engle on High-Frequency Trading and Portfolio Management

Nobel Laureate Robert Engle on High-Frequency Trading and Portfolio Management | Bounded Rationality and Beyond | Scoop.it

n part one of my interview with Nobel laureate Robert Engle, we discussed the development of the ARCH model, the global financial crisis, systemic risk, and forecasting liquidity with ARCH models. In this part, we will cover the application of ARCH models in high-frequency trading and how he thinks risk models should be applied in portfolio management.

CFA Institute: Let’s switch gears and talk about some of the most practical ways traders and portfolio managers leverage risk modeling. How about we start with high-frequency trading?

Robert Engle: There is no reason why you can’t calculate value at risk at a millisecond interval, except that we probably need a better volatility model, a volatility model that is specific to the time frame. One way people have done this is sort of what I call the brute force approach, which is you take thousands of observations every day, then you take thousands of observations the next day, put them all together to make them a million observations long, and fit it into the GARCH model. And it turns out that doesn’t work very well because it spends most of its effort predicting time of day shapes. So the decay rates of volatility are like an hour long. It predicts two days ahead. The volatility is not affected by what we know today. And we know that is not true. We need a more complex model.

Stirling Behavioural Science Blog : Nudging down under: article on the New South Wales Behavioural Insights Team

Stirling Behavioural Science Blog : Nudging down under: article on the New South Wales Behavioural Insights Team | Bounded Rationality and Beyond | Scoop.it
"In 2012, the New South Wales Department of Premier and Cabinet brought in one of the UK’s senior nudgers, Dr Rory Gallagher, to help establish its own taskforce, where he remains as managing adviser.The NSW Behavioural Insights Unit now claims impressive results of its own. Last month, it hosted the first ever international BI conference in Sydney. Several hundred delegates joined leading academics and practitioners in the emerging field — almost exclusively from the UK, the United States, Singapore and Australia — to discuss ways of gently nudging citizens by exploiting their cognitive biases, rather than coercing them.“What we’re trying to do is design and deliver government services around the way people actually behave,” Gallagher explained.Based on the nudge unit’s trials, the NSW Office of State Revenue is rolling out new penalty notices and reminders that are forecast to get an extra $10 million worth of fines paid on time each year, saving $80,000 in printing costs alone. The people encouraged to pay on time are expected to avoid about $4 million in extra penalties.At Westmead Hospital, the nudge unit helped increase the number of emergency in-patients who use their private health insurance by two percentage points. At Auburn Hospital, the same techniques tripled the number of patients using their private cover and, when used in two more local health districts, are expected to nudge the state’s bottom line to the tune of $11 million.A trial of ways to nudge injured employees back to work sooner finishes up this month. So far, those in the trial group have been back to full capacity 27% faster than the control group, and are three times as likely to have completed their claims within 30 days. #neuroeconomcs #behavioraleconomics

Stirling Behavioural Science Blog : Loss aversion in penalty shootouts

Stirling Behavioural Science Blog : Loss aversion in penalty shootouts | Bounded Rationality and Beyond | Scoop.it

Kahneman discusses this phenomenon in his book Thinking Fast and Slow in the context of golf, where loss aversion actually improves performance:

"Failing to make par is a loss, but missing a birdies putt is a foregone gain, not a loss. [Devin] Pope and [Maurice] Schweitzer reasoned from loss aversion that players would try a little harder when putting for par (to avoid a bogey) than when putting for a birdie. They analyzed more than 2.5 million putts in exquisite detail to test that prediction. They were right. Whether the putt was easy or hard, at every distance from the hole, the players were more successful when putting for par [i.e. avoiding a loss] than for a birdie [i.e. achieving a gain]. The difference in their rate of success when going for par (to avoid a bogey) or for a birdie was 3.6%. 

This difference is not trivial. Tiger Woods was one of the "participants" in their study. If in his best years Tiger Woods had managed to putt as well for birdies as he did for par, his average tournament score would have improved by one stroke and his earnings by almost $1 million per season."

Chapter 18: Risk Perception and Risk Tolerance by Victor Ricciardi, Douglas Rice :: SSRN

Chapter 18: Risk Perception and Risk Tolerance by Victor Ricciardi, Douglas Rice :: SSRN | Bounded Rationality and Beyond | Scoop.it
Abstract:      
This chapter provides an overview of the research literature and the important issues regarding risk perception and risk tolerance. The academic literature reveals that various disciplines provide an assortment of perspectives in terms of how to define, describe, and analyze risk. The behavioral finance perspective encompasses the subjective and objective factors of risk within the domains of risk perception and risk tolerance. Risk perception is the subjective decision-making process that an investor uses when evaluating risk and the amount of uncertainty. Risk tolerance is the degree of risk that an investor is willing to endure in the pursuit of a financial objective. A major problem within the risk tolerance literature is the lack of general agreement about issues such as a standard definition, a uniform theory or model, measurement discrepancies, and the growing number of questionnaires. Academic researchers and practitioners are only now starting to study and understand the long-term effects of the financial crisis in 2007 and 2008 on investor risk-taking behavior.

What is Cognitive Science? An introduction to the mind from the view points of: neuroscience, anthropology, computer science, psychology, philosophy, and linguistics. | Bounded Rationality and Beyond | Scoop.it
Cognitive science is partly defined as the study of thought, learning, and mentalorganization, which are all investigable functions of the human brain. Therefore, byunderstanding the principles of the brain, we can take a step forward in holistically knowing whatthe mind is.Neuroscience and ConsciousnessThe brain is comprised of billions of neurons. Neurons are the fundamental cells in thebrain that communicate to perform most bodily functions and higher-level cognitions. The thingthat makes these cells unique is that they are plastic and able to adapt based on the experiencesthey encounter. Scientists' ability to study the connections and specific importances of groups ofneurons across the brain contributes to the understanding of how humans learn, think, andchange.Various behavioral methods like electroencephalography (EEG) and functional magneticresonance imaging (fMRI) allow us to record neural action in the brain during various tasksrelating to cognitive function. By using these techniques, and others, it has been proven that thefrontal lobe of the brain plays a large part in higher-level cognitive functions like analyzinginformation, solving future problems, developing strategies, and controlling purposeful behaviors.This is significant because lower-level primates do not have developed frontal lobes andtherefore are unable to complete these complex actions. This ability to perform higher-levelfunctions, that aren't simply primitive or instinctive responses, is what makes us distinctlyhuman, and ultimately what composes our unique conscious mind.While neuroscience can solve many questions about what it truly means to be aconscious being (like the ability to control instinctive behaviors), it cannot answer them all. Somehuman functions still remain mysterious because neuroscience can't pin down concepts likefree will or behavioral control. In conclusion, the mind is certainly an emergence from the brain,but it isn't necessarily a distinct subject that can be entirely comprehended by science in today’stime.3

Beyond Brand Tracking: Measuring the Impact of Campaigns in a Multi-Dimensional World on Vimeo

Each year, advertisers spend very large portions of their budgets on promoting their brands via increasingly more integrated marketing campaigns; however, understanding the return on these investments has always been a challenge. 

Constant changes in media, the advance of digital and the plethora of touchpoints that make up potential consumer engagement have simply made the picture more complex. Never before have brands had so many tools at their disposal to engage with consumers, promote their products and interact with their targets. What was once a relatively simple decision in terms of budget allocation and creative optimisation has become an extremely complex puzzle.

System 1 Brand Tracking measures the effectiveness and contribution of each element of a campaign and their impact on brand equity through an innovative approach inspired by the latest advances in behavioural science. Furthermore, it delivers where traditional brand tracking cannot - by revealing the emotionally charged relationship between a consumer and a brand, and delivering key takeaways to foster the emotional bond.

Gabriel Aleixo, Managing Director - LatAm, discusses case studies that demonstrate a more effective approach to brand tracking and measurement of integrated marketing campaigns, and the key driver to brand success - how consumers feel.

Expert violinists can't tell old from new

Expert violinists can't tell old from new | Bounded Rationality and Beyond | Scoop.it

In PNAS, Fritz et al. (1) follow up their groundbreaking 2012 paper with what will probably be the final nail in the coffin for those who would believe that old musical instruments sound demonstrably better than new instruments. Their study used six prized instruments, Stradivari and Guarneri “del Gesu” violins, and six modern violins. World class violinists who were literally blind to provenance (the violinists wore goggles that dramatically reduced their ability to see) were given two opportunities to play them: in a small salon and in a concert hall. They were allowed to bring a friend to act as a second judge. Their task was to rank order the violins in terms of desirability and to label them as old vs. new. These highly trained and highly discerning musicians utterly failed at detecting old vs. new and showed no consistent preferences.

The study balanced rigor with real-world considerations and represents the most ecologically valid conditions possible while maintaining strict experimental protocols. Yet, intriguingly, the participants themselves remained unconvinced, even after having seen the results with their own eyes (or heard them with their own ears). Said one, “the one thing that you cannot put into a new violin is that it’s been played for 300 years—these instruments change and develop.” Said another, “I would absolutely buy a new instrument, but for a later generation. They need to be broken in” (2).

Why is it that musicians and scientists reach different conclusions when considering the same data? This arises in part due to different ways of knowing things. Scientists know what they know through systematic observation of the external world, mediated by replicable experiments and objective measurement. Artists know what they know through emotional experience, subjectivity, and intuition. When they …

The Intuitive Investor: A Simple Model of Intuition

The Intuitive Investor: A Simple Model of Intuition | Bounded Rationality and Beyond | Scoop.it
In part two of this new series, we present a simple model for intuition that provides a framework for understanding how to take advantage of its strengths and avoid its weaknesses.

Last month, I started a regular column on the power of intuition in investing that inspired many of you to write to me directly to discuss your experiences. While most of you viewed intuition positively, your responses indicated you still weren’t sure how to define it (i.e., that it lacked a central idea). You also expressed some reservations about applying intuition to investing because it is perceived as unreliable. Both these observations stem from the fact that we lack a simple, broadly adopted model of intuition to aid our understanding. With that in mind, here is my model. I hope it provides you with greater clarity.

A Simple Model of Intuition

Intuition is neither System 1 nor System 2 thinking as defined by Daniel Kahneman. Instead, intuition is a different category of mental action that is distinct from both instinct and deliberation. Intuition is a sense exactly like the five standard senses. Here is a simple model for understanding intuition as a sense:
