Behavioral Economics is the study of psychology as it relates to the economic decision-making processes of individuals and institutions. The two most important questions in this field are:. Are economists’ assumptions of utility or profit maximization good approximations of real people’s behavior? Behavioral economics is often related with normative economics. In an ideal world, people would always make optimal decisions that provide them with the greatest benefit and satisfaction.

Inpsychologist Daniel Kahneman was awarded the Nobel Memorial Prize in Economic Sciences «for having integrated insights from psychological research into economic science, especially concerning human judgment and decision-making under uncertainty».

Shiller received the Nobel Memorial Prize in Economic Sciences «for his empirical analysis of asset prices» within the field of behavioral finance [6]. Ineconomist Richard Thaler was awarded the Nobel Memorial Prize in Economic Sciences for «his contributions to behavioral economics and his pioneering work in establishing that people are predictably irrational in ways that defy economic theory».

During the classical period of economics, microeconomics was closely linked to psychology. For example, Adam Smith wrote The Theory of Moral Sentimentswhich proposed psychological explanations of invexting behavior, including concerns about fairness and justice. Then, during the development of neo-classical economicseconomists sought to reshape the discipline as a natural sciencededucing behavior from assumptions about the nature of economic agents.

They developed the concept of homo beehavioralwhose behavior was econlmics rational. Neo-classical economists did incorporate psychological explanations: this was true of Francis EdgeworthVilfredo Pareto and Irving Fisher. Economic psychology emerged in the 20th century in the works of Gabriel Tarde[10] George Ecoonmics[11] and Laszlo Garai. Observed and repeatable anomalies eventually challenged those hypotheses, and further steps were taken by Maurice Allaisfor example, in setting out the Allais paradoxa decision problem he first presented in that contradicts ecknomics expected utility hypothesis.

In behaviroal s cognitive psychology began to shed more light on the brain as an information processing device in contrast to behaviorist models.

Psychologists in this field, such as Ward Edwards, [13] Amos Behzvioral and Daniel Kahneman began to compare their cognitive models of decision-making under risk and uncertainty to economic models of rational behavior. Mathematical psychology reflects a longstanding interest in preference transitivity and the measurement of utility.

Bounded rationality is the idea that when individuals make decisions, their rationality is limited by the tractability of the decision problem, their cognitive limitations and the time available. Decision-makers in this view act as satisficersseeking a satisfactory solution rather than an optimal one. Herbert A. Simon proposed bounded rationality as an alternative basis for the mathematical modeling of decision-making. It complements «rationality as optimization», which views decision-making as a fully rational process bhavioral finding an optimal choice given the information available.

Bounded rationality implicates the idea that humans take shortcuts that may lead to suboptimal decision-making. Behavioral economists engage in mapping the decision shortcuts that agents use in order to help increase the effectiveness of human decision-making. A widely cited proposal from Sunstein and Thaler urges that healthier food be placed at sight level in order to increase the likelihood that a person will opt for that choice instead of less healthy option.

Some critics of Nudge have lodged attacks that modifying choice architectures invesring lead to people becoming worse decision-makers. InKahneman and Tversky published Prospect Theory : An Analysis of Decision Under Riskthat used cognitive psychology behaviorsl explain various divergences of economic decision making from neo-classical theory.

In the editing stage, risky situations are simplified using various heuristics. In the evaluation phase, risky alternatives are evaluated using various psychological principles that include:. Prospect theory is able to explain everything that the two main existing decision theories— expected utility theory and rank dependent utility theory—can explain.

Further, prospect theory has been used to explain phenomena that existing decision theories have great difficulty in explaining. These include backward bending labor supply curvesasymmetric price elasticities, tax evasion and co-movement of stock prices and consumption.

Inin the Journal of Risk and UncertaintyKahneman and Tversky gave a revised account of prospect theory that they called cumulative prospect theory.

Its main feature was that it allowed for non-linear probability weighting in a cumulative manner, which was originally suggested in John Quiggin ‘s rank-dependent utility theory.

Psychological traits such as overconfidenceprojection biasand the effects of limited attention are now part of the theory. Other developments include a conference at the University of Chicago[22] a special behavioral economics edition of the Quarterly Journal of Economics «In Memory of Amos Tversky»and Kahneman’s Nobel Prize for having «integrated insights from psychological research into economic science, especially concerning human judgment and decision-making under uncertainty».

Behavioral economics has been applied to intertemporal choice. Intertemporal choice is defined as making a decision and having the effects of such decision happening in a different time.

Intertemporal choice behavior is largely behavkoral, as exemplified by George Ainslie ‘s hyperbolic discounting —one of the prominently studied observations—and further developed by David LaibsonTed O’Donoghue and Matthew Rabin. Hyperbolic discounting describes the tendency to discount outcomes in the near future more than outcomes in the far future. This pattern can also be explained through models of sub-additive discounting that distinguish the delay and interval of discounting: people are less patient per-time-unit over shorter intervals regardless of when they occur.

Other branches of behavioral economics enrich the model of the utility function without implying inconsistency in preferences. Ernst FehrArmin Falkand Rabin studied fairnessinequity aversion and reciprocal altruismweakening the neoclassical assumption of perfect selfishness.

This work is particularly applicable to wage setting. The work on «intrinsic motivation by Gneezy and Rustichini and «identity» by Akerlof and Kranton assumes that agents derive utility from adopting personal and social norms in addition to conditional expected utility. According to Aggarwal, in addition to behavioral deviations from rational equilibrium, markets are also likely to suffer from lagged responses, search costs, externalities of the commons, and other frictions making it difficult to disentangle behavioral effects in market behavior.

Behavioral economics caught on among the general public with the success of books such as Dan Ariely ‘s Predictably Irrational. Practitioners of the discipline have studied quasi-public policy topics such as broadband mapping. Applications for behavioral economics include the modeling of the consumer decision-making process for applications in artificial intelligence and machine learning. Applications of behavioral economics also exist in other disciplines, for example in the area of supply chain management.

From a biological point sconomics view, human behaviors are essentially the same during crises accompanied by stock market crashes and during bubble growth when share prices exceed historic highs. During those periods, most market participants see something new for themselves, and this inevitably induces a stress response in them with accompanying changes in their endocrine profiles and motivations.

The result is quantitative and qualitative investinf in behavior. This is one example where behavior affecting economics and finance can be observed and variably-contrasted using behavioral economics. Behavioral economics’ usefulness applies beyond environments similar to stock exchanges.

Selfish-reasoning, ‘adult behaviors’, and similar, can be identified within criminal-concealment sand legal-deficiencies and neglect of different types can be observed and discovered. Awareness of indirect consequence or lack ofat least in potential with different experimental ecomomics and methods, can be used as well—behavioral economics’ potential uses are broad, but its reliability needs scrutiny.

Underestimation of the role of novelty as a stressor is the primary shortcoming of current approaches for market research. It is necessary to account for the biologically determined diphasisms of human behavior in everyday low-stress conditions and in response to stressors. Critics of behavioral economics typically stress the rationality of economic agents. Others note that cognitive theories, such as prospect theoryare models of decision-makingnot generalized ecconomics behavior, and are only applicable to the sort of once-off decision problems presented to experiment participants or survey respondents.

A notable concern is that despite a great deal of rhetoric, no unified behavioral theory has yet been espoused: behavioral economists have proposed no unified theory. David Gal has argued that many of these issues stem from behavioral economics being too concerned with understanding how behavior deviates from standard economic models rather than with understanding why people behave the way they.

Understanding why behavior occurs is necessary for the creation of generalizable knowledge, the goal of behwvioral. He has referred to behavioral economics as a «triumph of marketing» and particularly cited the example of loss aversion. Traditional economists are skeptical of the experimental and survey-based techniques that behavioral economics uses extensively.

Economists typically stress revealed preferences over stated preferences from surveys in the determination of economic value. Experiments and surveys are at risk of systemic biasesstrategic behavior and lack of incentive compatibility.

Matthew Rabin [34] dismisses these criticisms, countering that consistent results typically are obtained in multiple situations and geographies and can produce good theoretical insight. Behavioral economists, however, responded to these criticisms by focusing on field studies rather than lab experiments.

Some economists see a fundamental schism between experimental economics and behavioral economics, but prominent behavioral and experimental economists tend to share techniques and approaches in answering common questions.

For example, behavioral economists are investigating neuroeconomicswhich is entirely experimental and has inveting been verified in the field. The epistemological, ontological, and methodological components of behavioral economics are increasingly debated, in particular by historians of economics and economic methodologists. According to some researchers, [31] when studying the mechanisms that form the basis of decision-making, especially financial decision-making, it is necessary to recognize that most decisions are made under stress [36] because, «Stress is the nonspecific body response to any demands presented to it.

Nudge is a concept in behavioral sciencepolitical theory and economics which proposes positive reinforcement and indirect suggestions as ways to influence the behavior and decision making of groups or individuals. Nudging contrasts with other ways to achieve compliance, such as educationlegislation or enforcement. The concept has influenced British and American politicians.

The first formulation of the term and associated principles was developed in cybernetics by James Wilk before and described by Brunel University academic D. Stewart as «the art of the nudge» sometimes referred to as micronudges [38]. It also drew on methodological influences from clinical psychotherapy tracing back to Gregory Batesonincluding contributions from Milton EricksonWatzlawickWeakland and Fisch, and Bill O’Hanlon.

It also gained a following among US and UK politicians, in the private sector and in public health. A nudge, as we will use the term, is any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives. To count as a mere nudge, the intervention must be easy and cheap to avoid.

Nudges are not mandates. Putting fruit at eye level counts as a nudge. Banning junk food does not. In this form, drawing on behavioral economics, the nudge is more generally applied to influence investing behavioral economics. One of the most frequently cited examples of a nudge is the etching of the image of a housefly into the men’s room urinals at Amsterdam’s Schiphol Airport, which is intended to «improve the aim».

Nudging techniques aim to use judgmental heuristics to our advantage. In other words, a nudge alters the environment so that when heuristic, or System 1, decision-making is used, the resulting choice will be the most positive or desired outcome.

Inthe United States appointed Sunstein, who helped develop the theory, as administrator of the Office of Information and Regulatory Affairs. Notable applications of nudge theory include the formation of the British Behavioural Insights Team in Both Prime Minister David Cameron and President Barack Obama sought to employ nudge theory to advance domestic policy goals during their behaviiral. Nudge theory has also been applied to business management and corporate culturesuch as in relation to health, safety and environment HSE and human resources.

Regarding its application to HSE, one of the primary goals of nudge is to achieve a «zero accident culture». Leading Silicon Valley companies are forerunners in applying nudge theory in a corporate setting. These companies are using nudges in various forms to increase the productivity and happiness of employees. Recently, further companies are gaining interest in using what is called «nudge management» to improve the wconomics of their white-collar workers.

Behavioral insights and nudges are currently used in many countries around the world.

Efficient Market Hypothesis The Efficient Market Hypothesis, or EMH, was an investment theory that held that share prices reflect all information about a particular investment or market at all times, so investors can’t purchase undervalued stocks or sell stocks for inflated prices.
