Social preferences describe the human tendency to consider the well-being and intentions of others, along with one's own material gain, when making economic decisions. This concept falls under the umbrella of behavioral economics, a field that integrates insights from psychology and economics to understand how psychological factors influence financial decision-making. Unlike traditional economic models that assume individuals act solely out of self-interest to maximize their personal utility theory, social preferences acknowledge that factors such as fairness, altruism, and reciprocity can significantly shape choices.85, 86
History and Origin
The study of social preferences gained significant traction in economics through experimental methods in the 1980s. Early experiments consistently showed that individuals' behavior often deviated systematically from predictions based purely on self-interest84. A seminal experiment in this area is the Ultimatum Game, first introduced by German economists Werner Güth, Rolf Schmittberger, and Bernd Schwarze in 1982.82, 83 In this game, one player (the proposer) offers a portion of a sum of money to a second player (the responder). If the responder accepts, the money is divided as proposed; if rejected, neither player receives anything.80, 81
Traditional game theory predicts that the proposer would offer the smallest possible amount, and the responder would accept any non-zero offer, as something is better than nothing.78, 79 However, empirical results from the Ultimatum Game consistently demonstrated that proposers often offer a substantial share (e.g., 40-50%), and responders frequently reject offers perceived as unfair, even if it means receiving nothing.76, 77 These findings challenged the strict assumption of rationality and self-interest in traditional economics, paving the way for the development of economic models that incorporate social preferences.

Interpreting Social Preferences
Interpreting social preferences involves recognizing that individuals' choices are influenced by more than just their personal financial outcomes. When an individual exhibits social preferences, their utility, or satisfaction, is not solely dependent on their own consumption or wealth but also on the payoffs of others and the perceived nature of the interaction.67, 68 This means that a person might derive satisfaction from helping others (altruism), from seeing equitable outcomes (fairness or inequity aversion), or from responding in kind to the actions of others (reciprocity).
66
For instance, in experimental settings, a person might reject a financially beneficial offer if they deem it unfair, or contribute to a public goods initiative even when free-riding would be personally optimal. These behaviors are interpreted as evidence that individuals incorporate social considerations into their decision-making, often at a personal cost.

Hypothetical Example
Consider a simplified scenario involving two investors, Alice and Bob, who are partners in a small venture. They have generated a profit of $1,000, and Alice, as the managing partner, must propose how to split this profit.
Scenario 1: Pure Self-Interest (Traditional Economic View)
If Alice were to act purely on self-interest, she might propose to keep $990 for herself and offer Bob $10, assuming Bob, being rational, would accept anything greater than zero.
Scenario 2: With Social Preferences
Recognizing Bob's potential for social preferences and her own desire for a fair outcome, Alice proposes to split the profit 60/40, giving herself $600 and Bob $400. Bob, driven by a sense of fairness and the recognition of Alice's reasonable offer, readily accepts. Even if Alice could have gotten away with a smaller offer, her social preferences (or an anticipation of Bob's social preferences) led her to propose a more equitable split, ensuring cooperation and maintaining a positive working relationship. This outcome deviates from strict self-interest maximization and highlights the influence of social preferences on decision-making.
Practical Applications
Social preferences have wide-ranging practical applications in various economic and financial domains. In financial markets, they can influence investment behavior, particularly in the growing area of socially responsible investing (SRI) and environmental, social, and governance (ESG) factors. Investors with stronger social preferences may prioritize companies that align with their values, even if it means potentially accepting lower financial returns, demonstrating a willingness to sacrifice personal material gain for broader societal impact.62, 63 This shift highlights how investor preferences can influence capital allocation beyond traditional risk-return trade-offs.
61
Furthermore, understanding social preferences is crucial for designing effective public policies and incentives. Governments and organizations can leverage these insights to encourage prosocial behaviors, such as tax compliance, charitable giving, or participation in public goods initiatives.59, 60 For example, studies have shown that appeals to fairness or reciprocity can be more effective than purely monetary incentives in promoting cooperation. The Financial Times has reported on how investors are increasingly choosing purpose over pure profit, indicating a significant impact of social preferences on market dynamics and corporate strategies.

Limitations and Criticisms
While the concept of social preferences offers a more nuanced understanding of human behavior in economics, it also faces limitations and criticisms. One primary challenge lies in the variability and context-dependency of these preferences. What is considered "fair" or how strong an individual's altruistic tendencies are can vary widely across cultures, situations, and even over time.58 This makes it difficult to establish universal parameters for social preferences that can be consistently applied in all economic models.
57
Critics also point out the complexity of disentangling true social preferences from other motivations, such as reputation building or the avoidance of social sanctions. An individual might act prosocially not out of genuine altruism, but to gain approval or avoid a negative perception, which could be seen as a form of long-term self-interest. Additionally, incorporating social preferences into formal economic models can be challenging due to their subjective and often unobservable nature. Standard economic theories, such as rationality and utility theory, have been criticized for their unrealistic assumptions about human behavior.54, 55, 56 The International Monetary Fund (IMF) has discussed how integrating social preferences fundamentally changes economic analysis, posing challenges for traditional frameworks.

Social Preferences vs. Reciprocity
While closely related, social preferences and reciprocity are distinct concepts within behavioral economics. Social preferences is a broader term encompassing any deviation from purely self-interested behavior, where an individual's utility depends on the outcomes or intentions of others.53 This includes behaviors driven by altruism (unconditional kindness), fairness (desire for equitable distributions), or spite (desire to harm others).
52
Reciprocity, on the other hand, is a specific type of social preference characterized by a conditional response to another's actions. It means responding to perceived kindness with kindness, and perceived unkindness with unkindness, even if it is not in one's immediate material self-interest to do so.50, 51 For instance, in a trust game, a player might return more money than initially received because they perceive the other player's initial transfer as a kind gesture. While all reciprocal actions are manifestations of social preferences, not all social preferences (like pure altruism) involve reciprocity. Understanding this distinction helps in building more precise economic models of human interaction.

FAQs
What are common examples of social preferences?
Common examples of social preferences include giving to charity, volunteering time, participating in collective action for a common good, returning a lost wallet, or rejecting unfair offers in economic games like the Ultimatum Game. These actions often involve a personal cost but benefit others or uphold a sense of fairness.
How do social preferences impact financial markets?
In financial markets, social preferences influence decisions such as investing in companies with strong environmental, social, and governance (ESG) practices, boycotting companies perceived as unethical, or engaging in impact investing. These choices suggest investors derive non-financial utility from aligning their portfolios with their values, going beyond pure risk aversion and expected financial returns.
47, 48
Are social preferences universal, or do they vary?
Research in experimental economics suggests that while social preferences are observed across diverse cultures and populations, their specific manifestations and strength can vary.46 Factors such as cultural norms, economic conditions, and the specific context of a decision-making situation can influence how prominently social preferences are displayed.
How do social preferences relate to traditional economic theory?
Social preferences challenge the core assumption of pure self-interest in traditional economic models. The presence of social preferences helps explain behaviors that deviate from predictions based on strict rationality and utility maximization, leading to the development of behavioral economics which incorporates psychological insights like cognitive biases to better explain real-world economic phenomena.
44, 45
Can social preferences be measured?
Yes, social preferences are primarily measured through controlled laboratory experiments and field experiments, often using economic games such as the Ultimatum Game, Dictator Game, and Public Goods Game. These games are designed to elicit choices that reveal individuals' willingness to sacrifice personal gain for the benefit of others or to uphold fairness.1, 234, 567, 891011, 12, [13](https://open.[42](https://www.numberanalytics.com/blog/look-social-preferences-modern-economics), 43ncl.ac.uk/academic-theories/28/rational-choice-theory/)14151641, 17[18](https://www.econstor.eu/bitstream[39](https://imotions.com/blog/learning/research-fundamentals/the-ultimatum-game/), 40/10419/84144/1/cesifo_wp4403.pdf)19, [20](https://www.researchgate.net/publication/311451947_Social_Preferences_and_Socially_Responsible_Investin[37](https://imotions.com/blog/learning/research-fundamentals/the-ultimatum-game/), 38g_A_Survey_of_US_Investors)21, [22](https://fte.org/teachers/teacher-resources/lesson-plans/is-capitalism-good-for-the-poor-2/the-ultimatum-game-app[35](https://www.labvanced.com/content/research/en/blog/2025-03-ultimatum-game/), 36endix-1/)2324, [25](https://polit.econ.kit.edu/downloads/SeminarSoSe21_SocialPrefere[33](https://imotions.com/blog/learning/research-fundamentals/the-ultimatum-game/), 34nces.pdf)26, 27[28](https://www.numberanalytics.com/blog/look-social-preferences-modern-eco[30](https://imotions.com/blog/learning/research-fundamentals/the-ultimatum-game/), 31, 32nomics)29
