Why the PAP fails miserably at behavioral economics

Why the PAP fails miserably at behavioral economics | Bounded Rationality and Beyond | Scoop.it

What is behavioral economics? It is in essence a marriage between economics and psychology. It is concerned with how social, cognitive and emotional factors affect the decisions and actions of individuals that ultimately result in certain economic outcomes, and in the context of this article, we are quite interested in productivity. Sometimes, behavior of individuals do not follow the outcomes of economic models, and that is where behavioral economics comes in to fill the gap, as it attempts to explain how actions of individuals are influenced by psychological factors which brings about certain economic outcomes as the end result.

Cognitive load and strategic sophistication - Munich Personal RePEc Archive

Cognitive load and strategic sophistication - Munich Personal RePEc Archive | Bounded Rationality and Beyond | Scoop.it
Abstract

 

We study the relationship between the cognitive load manipulation and strategic sophistication. The cognitive load manipulation is designed to reduce the subject's cognitive resources that are available for deliberation on a choice. In our experiment, subjects are placed under a high cognitive load (given a difficult number to remember) or a low cognitive load (given a number that is not difficult to remember). Subsequently, the subjects play a one-shot game then they are asked to recall the number. This procedure is repeated for various games. We find a nuanced and nonmonotonic relationship between cognitive load and strategic sophistication. This relationship is consistent with two effects. First, subjects under a high cognitive load tend to exhibit behavior consistent with the reduced ability to compute the optimal decision. Second, the cognitive load tends to affect the subject's perception of their relative standing in the distribution of the available cognitive resources. The net result of these two opposing effects depends on the strategic setting. Our experiment provides evidence on the literature that examines the relationship between measures of cognitive ability and strategic sophistication.

Neuroalgorithmicmedia - How algorithmic bidding in paid search mirrors how the human brain makes decisions. | Bounded Rationality and Beyond | Scoop.it
The human brain is the most advanced super computer in the universe, with over 100 billion neurons responsible for every conscious and subconscious decision/ action we make. It is hypothesized by some neuroscientists that the decisions we make are nothing more than the rate in which neurons fire within specific parts of our brain. Studies have demonstrated that the decisions we make are, in great part, executed within the orbitofrontal cortex. This is the brain’s decision engine. The decision process is influenced by a risk assessment and a reward assessment. The risk assessment modulated by the amygdala and the reward assessment modulated by the nucleus accumbens. The decision making process in our brains is quite a bit more complicated than the above, but for the most part these are the regions of our brains that modulate and carry out our decisions.

Nonverbal World - All about Nonverbal Communication: First Impression

Nonverbal World - All about Nonverbal Communication: First Impression | Bounded Rationality and Beyond | Scoop.it
‘First Impression’ always has been in talks of people living in towns. Catch phrases like “First impression is the last impression.”, “You never get second chance to make good impression.” and “First impression lasts longer.” are very popular. Appearing in front of somebody at very first time is all about making an (long lasting) impression on its mind. Thus, first meeting is given more weightage to - in both human and animal world.

Most of us always seek opportunities to impress others positively because it has an enormous importance especially for employment, business and courtship. However, most of us mistakenly equate positive impression with good appearance or ‘looks’ only. It’s not the whole truth! You’ll realize same after going through rest of this article. At least, you’ll start looking deep inside a person, apart of how it looks.

Implications of behavioural economics for financial literacy and public policy

Abstract

This paper summarizes and highlights different methodological approaches to behavioural economics in the context of the conventional economic wisdom and the implications of these different methodological approaches for financial literacy, related institutional change, and public policy. Conventional economics predicts no substantive improvement from improvements to financial literacy. The errors and biases approach to behavioural economics suggests limited improvements to decision making from financial education as errors and biases are largely hardwired in the brain. Government and expert intervention affecting individual choice behaviour is recommended. The evidence suggests that the bounded rationality approach to behavioural economics, with its focus on smart decision makers and the importance institutional and environment constraints on decision making, is the most promising lense through which to analyse financial decision making. From this perspective, financial decision making can be improved by providing decision makers with better quality information presented in a non-complex fashion, an institutional environment conducive to good decisions, an incentive structure that internalize externalities involved in financial decision making, and financial education that will facilitate making the best use of the information at hand within a specific decision-making environment.

Stirling Behavioural Science Blog : Summary of our fourth ESRC Workshop on Preferences and Personality (21/11/14)

Stirling Behavioural Science Blog : Summary of our fourth ESRC Workshop on Preferences and Personality (21/11/14) | Bounded Rationality and Beyond | Scoop.it
hanks everybody for attending our fourth ESRC workshop on “Personality and Preferences” in Stirling on Friday November 21st. It was the fourth of our six workshops funded by the ESRC that are taking place in 2014/15. 

We had excellent presentations and interesting discussions with many new ideas emerging from the different economic and psychological perspectives on common topics. Some of the main talking points which arose were:
The importance of the subjective versus the objective.
Average effects versus individual heterogeneity.
The differences between the measurement of economic preference parameters in experimental settings versus the psychological measurement of traits using scales and how both approaches can complement each other.
The external and internal validity of various economic and psychological measures.
Different standards to evaluate the quality of measures in economics and psychology.
The use of personality psychology to explain individual differences in biased decision-making.
The importance of background variables (e.g. social context) on economic preferences.
The malleability of preferences. 
The question why incentivised experiments are considered best practice in economics.
The domain-specificity of preferences.
The psychometrics of economic preferences and economic games. 
The change of preferences and personality over the life course. 
Preference measures in children and adults.
The difference between averages in personality and the distribution of personality.

Fear vs. Personality Type

Fear vs. Personality Type | Bounded Rationality and Beyond | Scoop.it
There are many factors to fear. The most important one however (And widely unknown) is the shocking fact that our capacity to experience fear is directly correlated with our capacity to experience love. In other words, we can't suppress fear while still maintaining the ability to experience great love. Numbing one or ignoring one, equally affects the other.

Interestingly enough, there is some science behind it. It's long been known that oxytocin is the neurohypophysial hormone associated with love. For example, large amounts of oxytocin are released during and after child birth. Some say, to prevent the mother from harming the baby as a result of the agony of child birth. More recent studies are beginning to show that oxytocin also plays a large role in fear. This may explain why suppressing fears also reduces our ability to love and connect with others. 

The more of our authentic selves we suppress, the less fear AND love we are vulnerable to experience, suppression being the opposite of vulnerability.

The Illusion of Confidence — Behavioral Economics

The Illusion of Confidence — Behavioral Economics | Bounded Rationality and Beyond | Scoop.it
As told by Daniel Kahneman 

A friend recommend me the book Thinking, Fast and Slow when I asked him for a good read in the field of behavioral science — I am an entry level enthusiast. Half way thru it, everything has made sense to me till now, as has the concept of confidence/overconfidence as discussed by the author.

The less we know about something, say, a subject or incident, the more confident we feel about it. It’s like a jigsaw puzzle. It’s easy to fill a jigsaw puzzle if there are less pieces in it. The puzzle is complete or almost complete with just a few pieces.

We can form a coherent story if we have less data points. And as soon as we form a coherent story, we feel it’s true — which might or might not be the case. A coherent story is the key. We believe it and hence feel confident about it. Sometimes overconfident. And rightly said — it’s an illusion.

P.S. No takeaway from this post. Just a feeling of oh, that’s so right is all you get after reading it.

In the winter of 2011, a handful of software engineers landed in Boston just ahead of a crippling snowstorm. They were there as part of Code for America, a program that places idealistic young coders and designers in city halls across the country for a year. They’d planned to spend it building a new website for Boston’s public schools, but within days of their arrival, the city all but shut down and the coders were stuck fielding calls in the city’s snow emergency center.

In such snowstorms, firefighters can waste precious minutes finding and digging out hydrants. A city employee told the CFA team that the planning department had a list of street addresses for Boston’s 13,000 hydrants. “We figured, ‘Surely someone on the block with a shovel would volunteer if they knew where to look,’” says Erik Michaels-Ober, one of the CFA coders. So they got out their laptops.

The behavioral economics of international diplomacy

The behavioral economics of international diplomacy | Bounded Rationality and Beyond | Scoop.it
The personal characteristics of diplomats influence what types of international agreements they prefer.

When America sends diplomats to international negotiations over big-ticket items like the new Trans-Pacific Partnership agreement, does it matter who they send, or how those diplomats think about cooperation? Is it better if the people we put on the airplane to Geneva have certain character traits? Should they be patient or seek more immediate rewards?  Should our diplomats be good at chess — able to think many moves ahead — or altruistic?

International relations scholars have typically ignored the personal characteristics of diplomats in favor of explanations that highlight underlying interests and power relations between governments and economies.  These factors are obviously important, but our new study (with Brad LeVeck and James Fowler) in the journal International Organization finds that American diplomats vary dramatically on how they perceive the value of international cooperation and the best ways to achieve it. It’s their personalities and skills, not how an agreement is designed, that explain these differences.

The best navigation idea I’ve seen since the Tube map

The best navigation idea I’ve seen since the Tube map | Bounded Rationality and Beyond | Scoop.it

Yet because cognitive fluency is intangible, its value is often under-rated. For instance, consider the effect of rebranding the London Overground as part of the Tube network. Much of the route existed for decades as the Silverlink train line. But since it did not appear on the Tube map, it was mentally invisible and so unused; ten years ago you felt a bit like Spencer Tracy stepping off the train in Bad Day at Black Rock. Now, as an orange route on the Tube map, it is insanely popular. The rebranding of the line may have contributed more than the new trains.

Last week I heard of another British idea which may be as important as Harry Beck’s in making navigation mentally easy: www.what3words.com divides the entire surface of the earth into 3m x 3m squares and identifies each with just three common words. So the middle of the Spectator garden is what3words.com/liked.foods.loudly — while the front door is take.notes.thus. There are about 60 trillion such combinations available.

Do NYC cab drivers quit too early when it rains? - Decision Science News

Do NYC cab drivers quit too early when it rains? - Decision Science News | Bounded Rationality and Beyond | Scoop.it
Do cab drivers ignore opportunities to make more money when it rains?

ABSTRACT

In a seminal paper, Camerer, Babcock, Loewenstein, and Thaler (1997) find that the wage elasticity of daily hours of work New York City (NYC) taxi drivers is negative and conclude that their labor supply behavior is consistent with target earning (having reference dependent preferences). I replicate and extend the CBLT analysis using data from all trips taken in all taxi cabs in NYC for the five years from 2009-2013. The overall pattern in my data is clear: drivers tend to respond positively to unanticipated as well as anticipated increases in earnings opportunities. This is consistent with the neoclassical optimizing model of labor supply and does not support the reference dependent preferences model.

I explore heterogeneity across drivers in their labor supply elasticities and consider whether new drivers differ from more experienced drivers in their behavior. I find substantial heterogeneity across drivers in their elasticities, but the estimated elasticities are generally positive and only rarely substantially negative. I also find that new drivers with smaller elasticities are more likely to exit the industry while drivers who remain learn quickly to be better optimizers (have positive labor supply elasticities that grow with experience).

n the years preceding the financial crisis of 2008, certain key phrases appeared over and again in the public discourse on investing.

One that stands out in my mind is that home prices in the United States haven’t declined nationally since the Great Depression. The phrase appeared in television commentary by pundits, statements by Federal Reserve officials, in analyst reports, and in private conversations with Wall Street analysts.

I discovered the phrase yet again when studying securities ranging from housing stocks like KB Home (KBH), to large international banks like Citigroup (C), to government-sponsored entities like Fannie Mae, to mortgage companies like Countrywide Financial, to insurer and major credit default swap underwriter AIG.

Predictable and Predictive Emotions: Explaining Cheap Signals and Trust Re-Extension

Predictable and Predictive Emotions: Explaining Cheap Signals and Trust Re-Extension | Bounded Rationality and Beyond | Scoop.it
Abstract

 

Despite normative predictions from economics and biology, unrelated strangers will often develop the trust necessary to reap gains from one-shot economic exchange opportunities. This appears to be especially true when declared intentions and emotions can be cheaply communicated. Perhaps even more puzzling to economists and biologists is the observation that anonymous and unrelated individuals, known to have breached trust, often make effective use of cheap signals, such as promises and apologies, to encourage trust re-extension. We used a pair of trust games with one-way communication and an emotion survey to investigate the role of emotions in regulating the propensity to message, apologize, re-extend trust, and demonstrate trustworthiness. This design allowed us to observe the endogenous emergence and natural distribution of trust-relevant behaviors, remedial strategies used by promise-breakers, their effects on behavior, and subsequent outcomes. We found that emotions triggered by interaction outcomes are predictable and also predict subsequent apology and trust re-extension. The role of emotions in behavioral regulation helps explain why messages are produced, when they can be trusted, and when trust will be re-extended.

EconPapers: Do Women Panic More Than Men? An Experimental Study on Financial Decision

By Hubert Janos Kiss, Ismael Rodriguez-Lara and Alfonso Rosa-García; Abstract: We report experimental evidence on gender differences in financial decision that involves three depositors choosing.

Abstract: We report experimental evidence on gender differences in financial decision that involves three depositors choosing between waiting or withdrawing their money from a common bank. We find that the position in the line, the fact of being observed and the observed decisions are key determinants to explain subjects’ behavior. Although both men and women value being observed, it has a greater effect on women’s decisions. Observing a withdrawal increases the likelihood of withdrawal but women and men do not react differently to what is observed, so they are equally likely to panic if a bank run is already underway. Interestingly, risk aversion has no predictive power on depositors’ behavior.

Weekend Reads for Finance Pros: Our Brains and "The Disease" of Busyness

Weekend Reads for Finance Pros: Our Brains and "The Disease" of Busyness | Bounded Rationality and Beyond | Scoop.it

I don’t know about you, but I have a very hard time sitting still and just “being” instead of “doing.” My idea of “relaxing” usually involves something physical: running, swimming, cooking, spring cleaning, doing whatever, so long as I’m on the move. It takes a lot of discipline to just “be” instead of “do.” Which is why a passage from a recent post on the On Being blog, “The Disease of Being Busy,” really struck me.

Omid Safi, director of Duke University’s Islamic Studies Center, writes: “This disease of being ‘busy’ (and let’s call it what it is, the dis-ease of being busy, when we are never at ease) is spiritually destructive to our health and well-being. It saps our ability to be fully present with those we love the most in our families, and keeps us from forming the kind of community that we all so desperately crave.” Stopping myself from being busy, in a sense, is about simplifying. As American author Henry D. Thoreau once said, “Our life is frittered away by detail . . . Simplicity, simplicity, simplicity! . . .  Simplify, simplify.” I can’t help but wonder how much of my life I fritter away with my obsession with detail. Busyness, it seems, is how I try to manage detail. Here are some other interesting reads, in case you missed them:

Economic complexity: A different way to look at the economy

Economic complexity: A different way to look at the economy | Bounded Rationality and Beyond | Scoop.it

By W. Brian Arthur; External Professor, Santa Fe Institute; Visiting Researcher, Palo Alto Research Center. 

Economics is a stately subject, one that has altered little since its modern foundations were laid in Victorian times. Now it is changing radically. Standard economics is suddenly being challenged by a number of new approaches: behavioral economics, neuroeconomics, new institutional economics. One of the new approaches came to life at the Santa Fe Institute: complexity economics.

Complexity economics got its start in 1987 when a now-famous conference of scientists and economists convened by physicist Philip Anderson and economist Kenneth Arrow met to discuss the economy as an evolving complex system. That conference gave birth a year later to the Institute’s first research program – the Economy as an Evolving Complex System – and I was asked to lead this. That program in turn has gone on to lay down a new and different way to look at the economy.

And one man’s quest to bring hundreds more back. 

EVERY FALL AT MAINE’S COMMON GROUND Country Fair, the Lollapalooza of sustainable agriculture, John Bunker sets out a display of eccentric apples. Last September, once again, they covered every possible size, shape, and color in the wide world of appleness. There was a gnarled little yellow thing called a Westfield Seek-No-Further; a purplish plum impostor called a Black Oxford; a massive, red-streaked Wolf River; and one of Thomas Jefferson’s go-to fruits, the Esopus Spitzenburg. Bunker is known in Maine as “The Apple Whisperer,” or simply “The Apple Guy,” and, after laboring for years in semi-obscurity, he has never been in more demand. Through the catalog of Fedco Trees, a mail-order company he founded in Maine 30 years ago, Bunker has sown the seeds of a grassroots apple revolution.

All weekend long, I watched people gravitate to what Bunker (“Bunk” to his friends, a category that seems to include half the population of Maine) calls “the vibrational pull” of a table laden with bright apples. “Baldwin!” said a tiny old man with white hair and intermittent teeth, pointing to a brick-red apple that was one of America’s most important until the frigid winter of 1933-34 knocked it into obscurity. “That’s the best!”

“A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point.” So wrote the celebrated Stanford University psychologist Leon Festinger, in a passage that might have been referring to climate change denial—the persistent rejection, on the part of so many Americans today, of what we know about global warming and its human causes. But it was too early for that—this was the 1950s—and Festinger was actually describing a famous case study in psychology.

Computation: Information, adaptation, and evolution in silico — Foundations & Frontiers — Medium | Bounded Rationality and Beyond | Scoop.it
In 1984 the nascent Santa Fe Institute sponsored two workshops on “Emerging Syntheses in Science,” at which the Institute’s founders brainstormed their plans for the future. At the time I was a beginning graduate student in computer science and had never heard of SFI, but reading the workshop proceedings a few years later, I was very excited by the Institute’s goal to “pursue research on a large number of highly complex and interactive systems which can be properly studied only in an interdisciplinary environment.”

The founders planned to define particular themes or programs that would benefit from the kind of intensive cross-disciplinary interaction offered by the new institute. SFI’s first official program, formed in 1987, was Economics. Before long, several influential players in the field took note of SFI’s novel interdisciplinary approach to economics, and the program grew quickly, in fact threatening to take over the fledgling organization.

Founder and first SFI President George Cowan wanted to make sure economics did not come to dominate. He wrote: “We had to start somewhere, but we also had to make sure from the beginning that economics didn’t become the one interest of the institute…I pushed hard to support at least one other program that would be equal in size to the economics program. We needed to broaden our academic agenda, and spread our bets.” Cowan’s push was to start a program in “adaptive computation.”

Emergence: A unifying theme for 21st century science — Foundations & Frontiers — Medium | Bounded Rationality and Beyond | Scoop.it
When electrons or atoms or individuals or societies interact with one another or their environment, the collective behavior of the whole is different from that of its parts. We call this resulting behavior emergent. Emergence thus refers to collective phenomena or behaviors in complex adaptive systems that are not present in their individual parts.

Examples of emergent behavior are everywhere around us, from birds flocking, fireflies synchronizing, ants colonizing, fish schooling, individuals self-organizing into neighborhoods in cities – all with no leaders or central control – to the Big Bang, the formation of galaxies and stars and planets, the evolution of life on earth from its origins until now, the folding of proteins, the assembly of cells, the crystallization of atoms in a liquid, the superconductivity of electrons in some metals, the changing global climate, or the development of consciousness in an infant.

Indeed, we live in an emergent universe in which it is difficult, if not impossible, to identify any existing interesting scientific problem or study any social or economic behavior that is not emergent.

Abstract: In Chinese culture, certain digits are lucky and others unlucky. We test how such numerological superstition affects financial decision in the China IPO market. We find that the frequency of lucky numerical stock listing codes exceeds what would be expected by chance. Also consistent with superstition effects, newly listed firms with lucky listing codes are initially traded at a premium after controlling for known determinants of valuation multiples, the lucky number premium dissipates within three years of the IPO, and lucky number firms experience inferior post-IPO abnormal returns.
