Social preferences

{{Short description|Human tendency to care about social outcomes}}

Social preferences describe the human tendency to not only care about one's own material payoff, but also the reference group's payoff or/and the intention that leads to the payoff.{{Cite book |last1=Carpenter |first1=Jeffrey |date=2008 |chapter=Social Preferences |title=The New Palgrave Dictionary of Economics |pages=1–5 |doi=10.1057/978-1-349-95121-5_1974-1 |isbn=978-1-349-95121-5}} Social preferences are studied extensively in behavioral and experimental economics and social psychology. Types of social preferences include altruism, fairness, reciprocity, and inequity aversion.{{Cite web |url=https://www.behavioraleconomics.com/resources/mini-encyclopedia-of-be/social-preferences/ |title=Social preferences |website=behavioraleconomics.com {{!}} The BE Hub |access-date=2019-11-25}} The field of economics originally assumed that humans were rational economic actors, and as it became apparent that this was not the case, the field began to change. The research of social preferences in economics started with lab experiments in 1980, where experimental economists found subjects' behavior deviated systematically from self-interest behavior in economic games such as ultimatum game and dictator game. These experimental findings then inspired various new economic models to characterize agent's altruism, fairness and reciprocity concern between 1990 and 2010. More recently, there are growing amounts of field experiments that study the shaping of social preference and its applications throughout society.{{Cite book |last1=Kianpour|first1=Mazaher |last2=Øverby | first2=Harald | last3=Kowalski | first3=Stewart | last4=Frantz | first4=Christopher|title=HCI for Cybersecurity, Privacy and Trust |chapter=Social Preferences in Decision Making Under Cybersecurity Risks and Uncertainties |date=2019 |series=Lecture Notes in Computer Science |volume=11594 |pages=149–163 |doi=10.1007/978-3-030-22351-9_10 |hdl=11250/2651189 |isbn=978-3-030-22350-2 |s2cid=197418470 |hdl-access=free }}

Determinants: [[nature vs. nurture]]

Social preferences are thought to come about by two different methods: nature and nurture. Whilst nature encompasses biological makeup and genetics, nurture refers to the social environment in which one develops. The majority of literature would support that “nature” influences social preferences more strongly whereas there is still research to support the heavy influence of sociocultural factors. Some of these factors include social distance between economic agents, the distribution of economic resources, social norms, religion and ethnicity.{{cite journal |last1=Fehr |first1=Ernst |title=On the Economics and Biology of Trust |journal=Journal of the European Economic Association |date=1 May 2009 |volume=7 |issue=2–3 |pages=235–266 |doi=10.1162/JEEA.2009.7.2-3.235|url=https://www.zora.uzh.ch/id/eprint/24363/1/JEEA.2009.7.2-3.235.pdf }}

Importance

An understanding of social preferences and the disparity that occurs across individuals and groups can help create models that better represent reality. Within the financial sector, research supports the existence of a positive relationship between the elements of trust and reciprocity to economic growth as observed in a reduction of defaults in lending programs as well as the effectiveness of government and central banking policy.{{cite journal |last1=Knack |first1=Stephen |last2=Keefer |first2=Philip |title=Does Social Capital Have an Economic Payoff? A Cross-Country Investigation |journal=The Quarterly Journal of Economics |date=1 November 1997 |volume=112 |issue=4 |pages=1251–1288 |doi=10.1162/003355300555475}} The well-functioning of social preferences may assist society in paving the way to new developments through a decrease in the likelihood of market failures as well as a reduction in transaction costs. Society may also utilize social preferences to increase the flow of information, transparency and accountability.{{cite journal |last1=Zak |first1=Paul J. |last2=Knack |first2=Stephen |title=Trust and Growth |journal=The Economic Journal |date=1 March 2001 |volume=111 |issue=470 |pages=295–321 |doi=10.1111/1468-0297.00609|url=https://repositorio.unal.edu.co/handle/unal/80117 }}

Formation

Biologists, social psychologists, and economists have proposed theories and documented evidence on the formation of social preferences over both the long run and the short run.{{Citation|last1=Lévy-Garboua|first1=Louis|chapter=Chapter 7 The Formation of Social Preferences: Some Lessons from Psychology and Biology|date=2006-01-01|title=Handbook of the Economics of Giving, Altruism and Reciprocity|volume=1|pages=545–613|editor-last=Kolm|editor-first=Serge-Christophe|series=Foundations|publisher=Elsevier|doi=10.1016/s1574-0714(06)01007-4|last2=Meidinger|first2=Claude|last3=Rapoport|first3=Benoît|editor2-last=Ythier|editor2-first=Jean Mercier|isbn=9780444506979}} The various theories explaining the formation and development of social preferences may be explained from a biological, cognitive and sociocultural perspective and are detailed as follows.

= Biological evolution =

== Kin selection ==

{{Main|Kin selection}}

Kin selection is an evolutionary strategy where some specific behavioral traits are favored to benefit close relatives' reproduction.{{Cite journal|last=Smith|first=J. Maynard|date=March 1964|title=Group Selection and Kin Selection|journal=Nature|volume=201|issue=4924|pages=1145–1147|doi=10.1038/2011145a0|issn=0028-0836|bibcode=1964Natur.201.1145S|s2cid=4177102}} Hence, behavior that appears altruistic can align with the theory of the selfish gene.{{Cite book|title=The Selfish Gene|last=Dawkins|first=Richard|publisher=Oxford University Press, Oxford.|year=1976}} Kin selection can explain altruistic behavior towards close relatives even at the cost of their own's survival, as long as one's sacrifice can help preserve a greater amount of the same genes in close relatives.{{Citation|last=Hamilton|first=W. D.|chapter=The Genetical Evolution of Social Behavior. I.|date=2017-07-12|pages=23–43|publisher=Routledge|isbn=978-0-203-79042-7|doi=10.4324/9780203790427-4|title=Group Selection}} For example, worker bees can die from attacking their predators in order to help preserve other bees' genes.

== Reciprocity selection ==

{{main|Reciprocal altruism|}}

Reciprocity selection suggests that one's altruistic act may evolve from the anticipation of future reciprocal altruistic behavior from others.{{Cite journal|last=Trivers|first=Robert L.|date=1971-03-01|title=The Evolution of Reciprocal Altruism|journal=The Quarterly Review of Biology|volume=46|issue=1|pages=35–57|doi=10.1086/406755|s2cid=19027999|issn=0033-5770}} An application of reciprocity selection in game theory is the Tit-For-Tat strategy in prisoner's dilemma, which is the strategy that the player cooperate at the initial encounter, and then follow the opponent's behavior on the previous encounter.{{Cite journal|last=Axelrod|first=Robert|date=March 1980|title=Effective Choice in the Prisoner's Dilemma|journal=Journal of Conflict Resolution|language=en-US|volume=24|issue=1|pages=3–25|doi=10.1177/002200278002400101|s2cid=143112198|issn=0022-0027}} Robert Axelrod and W. D. Hamilton showed that Tit-For-Tat strategy can be an evolutionary stable strategy in a population where the probability of repeated encounters between two persons in a population is above a certain threshold.{{Cite journal|last1=Axelrod|first1=R|last2=Hamilton|first2=W.|date=1981-03-27|title=The evolution of cooperation|journal=Science|volume=211|issue=4489|pages=1390–1396|doi=10.1126/science.7466396|pmid=7466396|issn=0036-8075|bibcode=1981Sci...211.1390A}}

= Social learning =

{{Main|Social learning theory}}

Psychologist Albert Bandura proposed that children learn about pro-social and moral behavior by imitating other pro-social models, including parents, other adults, and peers. There are also economic models proposing that parents transmit their social preferences to their children by demonstrating their own pro-social behavior.{{Cite journal|last1=Bisin|first1=Alberto|last2=Verdier|first2=Thierry|date=2001-04-01|title=The Economics of Cultural Transmission and the Dynamics of Preferences|journal=Journal of Economic Theory|volume=97|issue=2|pages=298–319|doi=10.1006/jeth.2000.2678|issn=0022-0531}}{{Cite journal|last1=Cox|first1=Donald|last2=Stark|first2=Oded|title=On the Demand for Grandchildren: Tied Transfers and the Demonstration Effect|journal=Handbook on the Economics of Happiness|doi=10.4337/9781847204158.00026|year=2007|isbn=9781847204158|url=http://irihs.ihs.ac.at/1575/1/es-158.pdf}} Bandura conducted extensive psychological experimentation into the extent to which children will emulate aggressive behaviour by exposing them to models displaying behaviour before observing the child's behaviour once left alone.{{cite journal |last1=Bandura |first1=Albert |title=Social Learning Theory of Aggression |journal=Journal of Communication |date=1 September 1978 |volume=28 |issue=3 |pages=12–29 |doi=10.1111/j.1460-2466.1978.tb01621.x|pmid=690254 |s2cid=39668638 }}

However, empirical support for parents' role in fostering pro-social behavior is mixed.{{Cite journal|last1=Arrondel|first1=Luc|last2=Masson|first2=Andre|date=2001|title=Family Transfers Involving Three Generations|journal=The Scandinavian Journal of Economics|language=en|volume=103|issue=3|pages=415–443|doi=10.1111/1467-9442.00253|issn=1467-9442}} For example, some researchers found a positive relation between the parent's use of induction and children's pro-social behavior,{{Citation|last1=Eisenberg|first1=Nancy|title=Prosocial Development|date=2007-06-01|work=Handbook of Child Psychology|publisher=John Wiley & Sons, Inc.|isbn=978-0-470-14765-8|last2=Fabes|first2=Richard A.|last3=Spinrad|first3=Tracy L.|doi=10.1002/9780470147658.chpsy0311}} and others found no correlation between parent's adoption of punitive techniques and children's pro-social behavior.

Regarding other sources of social learning, recent field experiments have provided causal evidences for positive effects of school program and mentoring program on forming social preferences,{{Cite journal|last1=Kosse|first1=Fabian|last2=Deckers|first2=Thomas|last3=Pinger|first3=Pia|last4=Schildberg-Hoerisch|first4=Hannah|last5=Falk|first5=Armin|date=2019-05-14|title=The Formation of Prosociality: Causal Evidence on the Role of Social Environment|journal=Journal of Political Economy|volume=128|issue=2|pages=434–467|doi=10.1086/704386|issn=0022-3808|hdl=10419/162918|s2cid=32027472|hdl-access=free}}{{Cite journal|last1=Cappelen|first1=Alexander|last2=List|first2=John|last3=Samek|first3=Anya|authorlink3=Anya Samek|last4=Tungodden|first4=Bertil|date=December 2016|title=The Effect of Early Education on Social Preferences|url=http://www.nber.org/papers/w22898.pdf|language=en|location=Cambridge, MA|pages=w22898|doi=10.3386/w22898|s2cid=149561260|doi-access=free}} and these research suggested that social interaction, prosocial role models as well as cultural transmission from family and school are potential mechanisms.

= Cognitive factors =

Psychologist Jean Piaget was among the first to propose that cognitive development is a prerequisite in moral judgment and behavior. He argued for the importance of social interaction with others rather than learning in moral development, which requires the understanding of both rules and others' behavior. Other important cognitive skills in fostering pro-social behavior include perspective taking and moral reasoning,{{Cite journal|last1=Batson|first1=C.

Evidences of social preferences

= Experimental evidences =

Many initial evidences of social preferences came from lab experiments where subjects play economic games with others. However, many research found that subjects' behavior robustly and systematically deviated from the prediction from self-interest hypothesis, but could be explained by social preferences including altruism, inequity aversion and reciprocity. The ultimatum game, the dictator game, the trust game and the gift-exchange game are exercises that used to understand social preferences and their implications.

= The Ultimatum Game =

Ultimatum game is one of the first experiments that shows self-interest hypothesis fails to predict people's behavior. In this game, the first mover proposes a split of a fixed amount, and the second mover decides to accept or reject the offer. If the second mover accepts the offer, the final payoff is exactly determined by the offer. However, if the second mover rejects the offer, both subjects will have zero payoff.{{Cite journal|last1=Güth|first1=Werner|last2=Schmittberger|first2=Rolf|last3=Schwarze|first3=Bernd|date=1982-12-01|title=An experimental analysis of ultimatum bargaining|journal=Journal of Economic Behavior & Organization|volume=3|issue=4|pages=367–388|doi=10.1016/0167-2681(82)90011-7|url=http://www.dklevine.com/archive/refs4291.pdf}} Contrary to the self-interest hypothesis's prediction that the first mover will propose zero amount and the second mover will accept the offer, experimenters found proposers will typically offer 25%-50% of the fixed amount, and responders tend to reject the offer when the split is below 20%.{{Cite journal|last1=Levitt|first1=Steven D|last2=List|first2=John A|date=April 2007|title=What Do Laboratory Experiments Measuring Social Preferences Reveal About the Real World?|journal=Journal of Economic Perspectives|volume=21|issue=2|pages=153–174|doi=10.1257/jep.21.2.153|s2cid=26940779|doi-access=free}}

= The Dictator Game =

A relevant game is dictator game, where one subject proposes the split of a fixed amount and the other subject is only allowed to accept the offer. The dictator game helps to isolate pure altruism from the strategic concern of the first mover (i.e. the first mover proposes a larger share to second mover to avoid second mover's rejection) in the ultimatum game.{{Cite journal|last1=Forsythe|first1=Robert|last2=Horowitz|first2=Joel L.|last3=Savin|first3=N.E.|last4=Sefton|first4=Martin|date=May 1994|title=Fairness in Simple Bargaining Experiments|journal=Games and Economic Behavior|volume=6|issue=3|pages=347–369|doi=10.1006/game.1994.1021}} In this game, the average share decreases to 20% of the fixed amount, however, more than 60% of the subjects still propose a positive offer.

= The Trust and Gift-Exchange Games =

Two other games, trust game (also called investment game) and gift-exchange game provide evidence for reciprocal behavior. In the trust game, the first mover is endowed with a fixed amount c, and decides the amount of money b to pass on to the second mover. This amount is multiplied by a factor of k when it reaches the second mover, and then the second mover decides how much of this amount (kb) is returned to the first mover.{{Cite journal|last1=Berg|first1=Joyce|last2=Dickhaut|first2=John|last3=McCabe|first3=Kevin|date=1995-07-01|title=Trust, Reciprocity, and Social History|journal=Games and Economic Behavior|volume=10|issue=1|pages=122–142|doi=10.1006/game.1995.1027|s2cid=144827131}} While self-interest model predicts no transfer and no return, experimenters found that first mover typically transfers roughly 50% of endowment and responder's return increases with the transfer. In gift exchange game, the first mover proposes some offer to the second mover and asks for certain effort level from the second mover, and then the second mover decides his/her effort that is costly but can increase first mover's payoff.{{Cite journal|last1=Fehr|first1=Ernst|last2=Kirchsteiger|first2=Georg|last3=Riedl|first3=Arno|date=1993-05-01|title=Does Fairness Prevent Market Clearing? An Experimental Investigation|journal=The Quarterly Journal of Economics|volume=108|issue=2|pages=437–459|doi=10.2307/2118338|jstor=2118338|url=https://dipot.ulb.ac.be/dspace/bitstream/2013/5927/3/1993QJE-FairnessPreventMarketClearing.pdf}} Also contrary to the self-interest prediction, first mover's offer in experiments is usually greater than zero, and the second mover's effort level increases with offer.

Prisoner's dilemma and its generalized game, public goods game also provide indirect evidence for social preference, and there are many evidences of conditional cooperation among subjects.{{Cite book|last1=Kagel|first1=John H.|chapter=9. Auctions A Survey of Experimental Research|date=2016-01-31|title=The Handbook of Experimental Economics, Volume Two|publisher=Princeton University Press|isbn=978-1-4008-8317-2|last2=Levin|first2=Dan|doi=10.1515/9781400883172-010}} The prisoner's dilemma game illustrates the fact that the process of cooperation itself can create incentives to not cooperate.{{cite journal |last1=Forst |first1=Brian |last2=Lucianovic |first2=Judith |title=The prisoner's dilemma: Theory and reality |journal=Journal of Criminal Justice |date=1 March 1977 |volume=5 |issue=1 |pages=55–64 |doi=10.1016/0047-2352(77)90025-3}} Each player may make a contribution to a notional public good before all contributions are summed and distributed to players where the "selfish" players are given the opportunity to "free ride". This game depicts the way in which consumers will tend to free ride without active intervention yet also the way consumers will change their behaviour with experience.

= Field evidences =

Many field evidences documented agent's fairness and reciprocal concern. For example, Daniel Kahneman, Jack Knetsch and Richard Thaler found that the concern for fairness constrains firm's profit seeking behavior (e.g. raise price after an increase in demand).{{Cite book|last1=Kahneman|first1=Daniel|chapter=Fairness as a Constraint on Profit Seeking: Entitlements in the Market|date=2000-09-25|title=Choices, Values, and Frames|pages=317–334|publisher=Cambridge University Press|isbn=978-0-511-80347-5|last2=Knetsch|first2=Jack L.|last3=Thaler|first3=Richard H.|doi=10.1017/cbo9780511803475.019|s2cid=756537}}

Many field experiments examine relative pay concerns and reciprocity in work settings. For example, economists Uri Gneezy and John List conducted field experiments where subjects were hired for a typing job and for door-to-door fundraising and found subjects exerted larger effort level in group with a higher wage. However, this positive reciprocity was short lived.{{Cite journal|last1=Gneezy|first1=Uri|last2=List|first2=John A|date=September 2006|title=Putting Behavioral Economics to Work: Testing for Gift Exchange in Labor Markets Using Field Experiments|journal=Econometrica|volume=74|issue=5|pages=1365–1384|doi=10.1111/j.1468-0262.2006.00707.x|url=http://www.nber.org/papers/w12063.pdf}} Researchers have also found that positive reciprocity is smaller than negative reciprocity. In another study, job applicants were hired to catalog books for 6 hours with a pronounced wage, but applicants were later informed with either wage increase or wage cut. Researchers found the decrease in effort in wage cut group was larger than the increase in effort in wage increase group. However, positive reciprocity did not extend to other activities (volunteering to work for one more hour).{{Cite journal|last1=Kube|first1=Sebastian|last2=Maréchal|first2=Michel André|last3=Puppe|first3=Clemens|date=2013-07-24|journal=Journal of the European Economic Association|volume=11|issue=4|pages=853–870|doi=10.1111/jeea.12022|title=Do Wage Cuts Damage Work Morale?

Economic models

Existing models of social preferences can be divided into two types: distributive preferences and reciprocal preferences. Distributive preferences are the preferences over the distribution and total magnitude of the payoff among the reference groups, including altruism and spitefulness, fairness and inequity aversion, and efficiency concern. Reciprocal preferences reflect agent's concern over the intention of other's behavior.{{Cite journal|last1=Charness|first1=Gary|last2=Rabin|first2=Matthew|date=2000|title=Understanding Social Preference with Simple Tests|doi=10.2139/ssrn.224577|s2cid=14074659}}

= Pure altruism, warm glow, and spitefulness =

Pure altruism in economic models represents an agent's concern on other's well-being. A person exhibits altruistic preference if this person's utility increases with other's payoff.{{Cite book|last1=Fehr|first1=Ernst|chapter=Chapter 8. The Economics of Fairness, Reciprocity and Altruism – Experimental Evidence and New Theories|chapter-url=https://www.researchgate.net/publication/4952588|date=2006|title=Handbook of the Economics of Giving, Altruism and Reciprocity|volume=1|pages=615–691|editor-last=Kolm|editor-first=Serge-Christophe|series=Foundations|publisher=Elsevier|doi=10.1016/s1574-0714(06)01008-6|last2=Schmidt|first2=Klaus M.|editor2-last=Ythier|editor2-first=Jean Mercier|isbn=9780444506979}}{{Cite journal|last=Levine|first=David K.|date=1998-07-01|title=Modeling Altruism and Spitefulness in Experiments|journal=Review of Economic Dynamics|volume=1|issue=3|pages=593–622|doi=10.1006/redy.1998.0023}} A related economic model is impure altruism, or warm-glow, where individuals feel good (i.e. gain a "warm-glow" utility) from doing something good without caring about other's payoff.{{Cite journal|last=Andreoni|first=James|date=1990-06-01|title=Impure Altruism and Donations to Public Goods: A Theory of Warm-Glow Giving|journal=The Economic Journal|volume=100|issue=401|pages=464–477|doi=10.2307/2234133|jstor=2234133|s2cid=6001457}} Spitefulness or envy preference is the opposite of pure altruism. In this instance, an agent's utility decreases with other's payoff.

= Fairness and inequity aversion =

Fairness and inequity aversion models capture the agent's concern on the fair distribution of payoffs across agents and especially the aversion to payoff differences.{{Cite journal|last1=Fehr|first1=Ernst|last2=Schmidt|first2=Klaus M.|date=1999-08-01|title=A Theory of Fairness, Competition, and Cooperation|journal=The Quarterly Journal of Economics|volume=114|issue=3|pages=817–868|doi=10.1162/003355399556151|hdl=10535/6398 |url=https://www.zora.uzh.ch/id/eprint/155543/1/ZORA_NL_155543.pdf}} In the Fehr-Schmidt model, an agent compares his payoff to each other opponents in the group. However, the agent's utility decreases with both positive and negative payoff differences between self and each other opponent in the reference group. Moreover, the agent dislikes payoff disadvantage more than payoff advantage. Hence, the agent presents altruistic behavior towards others when agent is better off than others, and displays spiteful behavior when agent is worse off than others.

= Efficiency concern and quasi-maximin preferences =

Economists Gary Charness and Matthew Rabin found that in some cases, agents prefer more efficient outcomes (i.e. outcome with larger social welfare) than more equal outcomes{{Cite journal|last1=Charness|first1=Gary|last2=Rabin|first2=Matthew|date=2002-08-01|title=Understanding Social Preferences with Simple Tests|journal=The Quarterly Journal of Economics|volume=117|issue=3|pages=817–869|doi=10.1162/003355302760193904|jstor=4132490|s2cid=221277798 |url=http://www.escholarship.org/uc/item/0dc3k4m5}} and they developed a model where agents' utility is a convex combination of own's material payoff and the social welfare. Moreover, they assumed agents have quasi-maximin preferences, meaning that agents' care on social welfare includes the minimum payoff among agents as well as the total payoff for all agents in the group. However, the agent will care less about others' payoff if other is better off than self.

= Reciprocity =

Agent has the motivation to reciprocate towards both kind and unfair behavior. Rabin (1993)'s model is one of the earliest model that characterizes reciprocal behavior. In this model, the agent's payoff depends on the other opponent, and agent forms belief of the other opponent's kindness, which is based on the difference between the actual payoff that agent receives and the fair payoff. Agents will reciprocate positively if he/she perceives the other individual's behavior as kind and fair and respond negatively if he/she perceives it as unfair.{{Cite book|last1 = Rabin|first1 = Matthew|chapter=Incorporating Fairness into Game Theory and Economics|date=2011|pages=297–325|publisher=Princeton University Press|isbn=978-1-4008-2911-8|doi=10.2307/j.ctvcm4j8j.15|title=Advances in Behavioral Economics|s2cid = 11831549|url = http://www.dklevine.com/archive/refs4511.pdf}} Other researchers further generalize Rabin (1993)'s model by studying repeated interactions in N-person extensive form games,{{Cite journal|last1=Dufwenberg|first1=Martin|last2=Kirchsteiger|first2=Georg|date=May 2004|title=A theory of sequential reciprocity|journal=Games and Economic Behavior|volume=47|issue=2|pages=268–298|doi=10.1016/j.geb.2003.06.003|s2cid=2508835 |url=http://www.dklevine.com/archive/a_theory.pdf}} and also by including inequity aversion into agent's preference.{{Cite journal|last1=Falk|first1=Armin|last2=Fischbacher|first2=Urs|date=2006-02-01|title=A theory of reciprocity|journal=Games and Economic Behavior|volume=54|issue=2|pages=293–315|doi=10.1016/j.geb.2005.03.001|s2cid=5714242}} Charness and Rabin also augmented their quasi-maximin preference with reciprocity concern.

Economic applications

Researchers have argued that the failure of recognizing social preference will lead to a biased understanding of much important economic behavior.{{Cite journal | doi=10.1111/1468-0297.00027 |title = Why Social Preferences Matter – the Impact of non-Selfish Motives on Competition, Cooperation and Incentives|journal = The Economic Journal|volume = 112|issue = 478|pages = C1–C33|year = 2002|last1 = Fehr|first1 = Ernst|last2 = Fischbacher|first2 = Urs|hdl = 20.500.11850/146625|jstor=798356|ssrn=299142|s2cid = 15380244|hdl-access = free}} Three important ways in which social preferences are applied to real world economics are explained below.

= Understanding cooperation =

Research on social preferences showed that reciprocal and inequity averse individuals can cooperate if they are sure that others will cooperate too and can punish the free riders. This has implications for designing proper social mechanisms to solve the free-riding problem. For example, Fischbacher and Gachter found that, through public goods experimentation, people contribute more to public goods than self-interest alone would suggest. This provides support for the notion of voluntary contribution.{{cite journal |last1=Fischbacher |first1=Urs |last2=Gächter |first2=Simon |title=Social Preferences, Beliefs, and the Dynamics of Free Riding in Public Goods Experiments |journal=The American Economic Review |date=2010 |volume=100 |issue=1 |pages=541–556 |doi=10.1257/aer.100.1.541 |jstor=27804940 |s2cid=8204954 |url=https://www.jstor.org/stable/27804940 |issn=0002-8282}}

= Design of economic incentive =

Accounting employee's reciprocity and fairness concerns can help design better contracts (e.g. trust contract, bonus contract) to enhance employee's effort and to solve firm's agency problems. Moreover, the design of relative pay in the workplace can affect employee's job satisfaction and well-being.{{Cite journal|last1=Breza|first1=Emily|last2=Kaur|first2=Supreet|last3=Shamdasani|first3=Yogita|date=2018-05-01|title=The Morale Effects of Pay Inequality|journal=The Quarterly Journal of Economics|volume=133|issue=2|pages=611–663|doi=10.1093/qje/qjx041|s2cid=15712813|url=http://www.nber.org/papers/w22491.pdf|doi-access=free}}Card, David; Mas, Alexandre; Moretti, Enrico; Saez, Emmanuel (2012). "Inequality at Work: The Effect of Peer Salaries on Job Satisfaction". American Economic Review. 102 (6): 2981–3003. doi:10.1257/aer.102.6.2981. Research on social preference has also facilitated the understanding of monetary incentives' crowding-out effect.{{Cite journal|title=Economic Incentives and Social Preferences: Substitutes or Complements?|url=http://repec.deps.unisi.it/quaderni/617.pdf|journal=Journal of Economic Literature|volume=50|issue=2|pages=368–425|doi=10.1257/jel.50.2.368|year=2012|last1=Bowles|first1=Samuel|last2=Polanía-Reyes|first2=Sandra}}

= Design of social policies =

The distributive and reciprocal preferences mentioned previously are integral in good government and the upholding of ethical standards. Without the existence of these preferences, it is unlikely that society would achieve desirable allocations of economic goods due to self-interest and the "free rider" problem. Research and experimentation into social preferences assists in the design of optimal incentives used in public policy.{{cite journal |last1=Bowles |first1=Samuel |last2=Hwang |first2=Sung-Ha |title=Social preferences and public economics: Mechanism design when social preferences depend on incentives |journal=Journal of Public Economics |date=1 August 2008 |volume=92 |issue=8 |pages=1811–1820 |doi=10.1016/j.jpubeco.2008.03.006|s2cid=8993775 |url=http://www.umass.edu/economics/publications/2008-06.pdf }} Accounting individual's fairness concerns can affect the design of the social policies, especially for redistributive policies. In addition, reciprocal preferences can affect people's evaluation of different policies towards the poor depending on the individual's belief that whether the poor are deserving or undeserving.{{Cite journal|last=Wax|first=Amy L.|date=2000|title=Rethinking Welfare Rights: Reciprocity Norms, Reactive Attitudes, and the Political Economy of Welfare Reform|journal=Law and Contemporary Problems|volume=63|issue=1|pages=257–298|doi=10.2139/ssrn.198928|url=https://scholarship.law.upenn.edu/context/faculty_scholarship/article/1748/viewcontent/Rethinking_Welfare_Rights__Reciprocity_Norms_Reactive_Attitudes.pdf}}
