THE ECONOMICS OF SOCIAL SENTIMENTS: THE CASE OF ENVY

The widespread externality produced by the sentiment of envy is modelled in this paper. We show its specific structural properties, the conditions of its existence, the various reasons for its normative relevance, the basic tool of its analysis ("envy-free preferences") and its crucial relation with the property of equality of liberty ("equity"). We then show that the envy externality respects the efficiency of classical allocative processes in the relevant conditions (competitive markets with not too unequal incomes, cases with indivisibilities, equal-freedom individual choices, etc.). We in particular derive conditions of consistency between efficiency and the vanishing of the envy externality, as well as the effects of actual envy on "divide and choose" processes, preferences to reassignment, multidimensional maximin, "egalitarian equivalence", degrees of envy in society and the rationality of choices.     

Envy and Altruism: Contrasting Bivariate and Univariate Prospect Preferences

We compare prospect ordering with and without envy and altruism. We find that envy can induce a violation of the univariate first‐degree stochastic dominance (FSD), and thus a violation of the classic expected utility monotonicity axiom. Surprisingly, altruism can also violate FSD preferences. The intuitive explanation of the result in the case of altruism hinges on the sign of the mixed derivative of the bivariate preference: the individual might prefer a certain correlation between her wealth and her peer group's wealth, and is therefore willing to violate FSD as long as the outcomes of the two parties are ordered according to her preferences. When investments are considered, envy and altruism can distort not only preferences but also actual choices.     

General allocation problems with single-peaked preferences: path-independence and related topics

We face the problem of allocationg a fixed amount of a perfectly divisible good among a group of agents with single-peaked preferences. We survey the three different cases studied in the literature: the pure distribution case, the redistribution case, and the gerneral case. The so called general case provide with a natural framework to analyze the idea of path-independence. In this framework, we explore the existence of rules fulfilling this property. Our first result is negative: a strong version of this property cannot be fulfilled together with efficiency. Nonetheless, some restricted versions of the path-independence property are compatible with interesting properties, in particular no manipulability, and no envy. We then identify two solutions satisfying this sort of property: the equal distance rule, and a new extension of the uniform rule.     

How context matters: A survey based experiment on distributive justice

We explore distributive justice and perception of fairness using survey data from freshmen and senior students of economics and sociology. We analyse the impact of context and education on their preferences over a hypothetical distribution of resources between individuals which presents a trade off between efficiency and equality. With context giving minimal information, economics students are less likely to favour equality; studying economics influences the preferences of the subjects, increasing this difference. However, when the same problem is inserted into a meaningful context, the difference disappears. Four distribution mechanisms are analysed: egalitarianism, maximin, utilitarianism and utilitarianism with a floor constraint.     

An Algorithm for Stable and Equitable Coalition Structures with Public Goods

We study the formation of coalitions that provide public goods to members. Individuals are linked on a tree graph and those with similar preferences are connected on the tree. We present a well‐defined solution that selects envy‐free allocations from the core.     

Purely procedural preferences - Beyond procedural equity and reciprocity

We conduct experiments in which parties face a pair of two-player pie-splitting procedures. Parties submit their strategy in each, their beliefs about their opponent's choices, and are also asked whether they prefer one procedure over the other. The procedures – a yes-no game, an ultimatum game, and a dictator game – are designed such that by all existing economic preference models, whether distributive or procedural, parties should be indifferent between them. In particular, the procedures should yield the same outcomes, the same expected outcomes and carry the same information on parties' intentions. At the same time, the procedures differ in the way they distribute decision and information rights across players, and also in their complexity and efficiency. Experimentally, parties do indeed still reveal preferences over the procedures at hand. To explore why this happens, we elicit individuals' simplicity and efficiency ratings of the procedures, and also the degree by which individuals invoke the equality of basic rights and liberties in their moral judgement – an ethical criterion not yet captured by any preference model. The preferences we find link to this data. We explore formalizations for such preferences.     

Rousseau's notion of envy: A comparison with modern economic theory

Abstract

The concept of envy is present both in Rousseau's economic philosophy and in modern economic theory. This paper compares these different uses of the concept and studies the relevance of the definition of envy adopted on each side, taking into account what is at stake when a notion of envy is introduced. It will be shown that Rousseau's envy cannot be expressed by modern conceptions of envy. Nevertheless, it enlightens the debate between the two competing notions of envy present in modern economic theory, revealing that the existence of envy questions the notion of self-interest.     

Social preferences and lying aversion in children

While previous research has shown that social preferences develop in childhood, we study whether this development is accompanied by reduced use of deception when lies would harm others, and increased use of deception to benefit others. In a sample of children aged between 7 and 14, we find strong aversion to lying at all ages. Lying is driven mainly by selfish motives and envy. Children with stronger social preferences are less prone to deception, even when lying would benefit others at no monetary cost. Older children lie less than younger children and use self-justification to lie.     

Existence of a Condorcet Winner When Voters Have Other‐Regarding Preferences

In standard political economy models, voters are “self‐interested” that is, care only about “own” utility. However, the emerging evidence indicates that voters often have “other‐regarding preferences” (ORP), that is, in deciding among alternative policies voters care about their payoffs relative to others. We extend a widely used general equilibrium framework in political economy to allow for voters with ORP, as in Fehr and Schmidt (1999) . In line with the evidence, these preferences allow voters to exhibit “envy” and “altruism,” in addition to the standard concern for “own utility.” We give sufficient conditions for the existence of a Condorcet winner when voters have ORP. This could open the way for an incorporation of ORP in a variety of political economy models. Furthermore, as a corollary, we give more general conditions for the existence of a Condorcet winner when voters have purely selfish preferences.     

The impossibility of compromise: some uniqueness properties of expected utility preferences

Summary. We focus on the following uniqueness property of expected utility preferences: Agreement of two preferences on one interior indifference class implies their equality. We show that, besides expected utility preferences under (objective) risk, this uniqueness property holds for subjective expected utility preferences in Anscombe-Aumann's (partially subjective) and Savage's (fully subjective) settings, while it does not hold for subjective expected utility preferences in settings without rich state spaces. Indeed, when it holds the uniqueness property is even stronger than described above, as it needs only agreement on binary acts. The extension of the uniqueness property to the subjective case is possible because beliefs in the mentioned settings are shown to satisfy an analogous property: If two decision makers agree on a likelihood indifference class, they must have identical beliefs.

Is the veil of ignorance only a concept about risk? An experiment

We implement the Rawlsian veil of ignorance in the laboratory. Our design allows analyzing the effects of risk and social preferences behind the veil of ignorance. Behind the veil of ignorance subjects choose more equal distributions than in front of the veil, but only a minority acts according to maximin preferences. Many subjects prefer more equal allocations not only for insurance purposes but also due to impartial social preferences for equality. Our results imply that behind the veil of ignorance maximin preferences are compatible with any degree of risk aversion if impartial social preferences for equality are sufficiently strong.     

基于公平偏好下的风险企业家道德风险研究

风险企业家在向风险投资家寻求融资共同发展风险项目的过程中表现出有限理性,具有公平偏好心理,其往往因为嫉妒心理而影响到自身的努力水平,这样,风险投资中的道德风险问题不可避免,进而会损害到风险投资家的利益。本文从有限理性的角度出发,通过设计针对具有公平偏好的风险企业家的有效激励机制,以此来分析和防范公平偏好心理带来的道德风险问题。研究表明,风险投资家应尽可能选择公平偏好程度较小的风险企业家作为投资对象,以减少或规避风险投资市场中的道德风险。     

Increasing risk with state-dependent preferences

A definition of increasing risk for state-dependent preferences is introduced and its usefulness for the analysis of concrete economic problems is illustrated. For classes of individuals with the same reference set the notion of increasing risk has three equivalent characterizations analogous to those obtained in the case of state-independent preferences. The definition is used to conduct a comparative statics analysis of a portfolio problem with state-dependent preferences.     

Envy and pricing of quality in adverse selection

The paper analyzes the optimal pricing of quality when consumers feel envious of other purchase deals. The influence of envy on the optimal pricing of quality varies depending on whether consumers are concerned about envy in payments or in rents. If consumers compare their payments with those of other consumers, the firm has an incentive to produce lower quality than the first-best level for the high valuation consumer and higher quality than the second-best level for the low valuation consumer. Conversely, when consumers’ disutility from envy arises from envy in rents, the trade-off between efficiency and rent extraction becomes more serious than in the situation where there is no envy.     

Sustainability with Uncertain Future Preferences

A feature of the sustainability problem is that the preferences of future generations are uncertain. In this paper, we put forward a fairness-based definition of sustainability that takes this uncertainty into account. We analyze the implications of this definition in the context of a model of project evaluation. We show that our definition encompasses the concepts of non-declining welfare and of weak and strong sustainability. Furthermore, we show that preference uncertainty has a substantial influence on the implications of sustainability. We are indebted to two anonymous referees whose comments helped considerably to improve the paper. All remaining errors are ours.

The Manipulability of Fair Solutions in Assignment of an Indivisible Object with Monetary Transfers

Public decision making often involves the problem of fairly assigning one indivisible object to agents with monetary transfers. An example is the choice of the location of a garbage incineration facility where the accepting district should receive fair compensations from other districts. In this problem, we show that for broad classes of solutions satisfying a welfare lower bound and an efficiency‐oriented condition, the set of equilibrium allocations in the manipulation game associated with a given solution coincides with the set of all envy‐free allocations. This generalizes Tadenuma and Thomson's equivalence result for a class of envy‐free solutions. Our result covers the Shapley value, which is not covered by Tadenuma and Thomson's result.     

Bivariate almost stochastic dominance

Univariate almost stochastic dominance has been widely studied and applied since its introduction by Leshno and Levy (Manag Sci 48:1074–1085, 2002). This paper extends this construction to the bivariate case by means of suitable two-attribute utility functions. After having confined correlation aversion and correlation loving to some acceptable levels, bivariate almost stochastic dominance rules are introduced for the preferences exhibiting confined correlation aversion and confined correlation loving. The impact of a change in risk in terms of bivariate almost stochastic dominance on optimal saving is analyzed as an application, as well as the effect of envy and altruism on income distributions. Finally, alternative definitions of bivariate almost stochastic dominance are discussed, as well as testing procedures for such dominance rules in financial problems.     

Do China's people favour redistribution? Evidence from an incentivized experiment

From 1949, China's leaders brought their country through three decades of income and wealth compression, which was followed by more than three decades of sharply rising inequality. What preferences do China's people hold regarding what price (if any) is worth paying for greater equality? We conduct a laboratory decision‐making experiment mimicking aspects of a macro‐political–economic environment, using Chinese undergraduate student subjects. We find that our subjects have qualitatively similar tastes for equality as their counterparts in parallel US and European experiments; for example, most are willing to sacrifice some payment for more equality of earnings among other participants, and their willingness to do this is stronger when inequalities originate randomly versus based on performance. Considering the cases permitting direct comparison between Chinese and US subjects’ choices, redistributive choices tend to be a bit higher in China if the participant pays no direct cost and a bit lower if he or she pays such a cost, but the two distributions of decisions differ significantly in under 14% of conditions. Survey data too suggests preferences for a more equal income distribution in China than in other East Asian countries, suggesting a possible impact of the Chinese Communist Party dominance in education and media.     

Group identification with (incomplete) preferences

We consider the problem of identifying members of a group based on individual opinions. Since agents do not have preferences in the model, properties of rules that concern preferences (e.g., strategy‐proofness and efficiency) have not been studied in the literature. We fill this gap by working with a class of incomplete preferences derived directly from opinions. Our main result characterizes a new family of group identification rules, called voting‐by‐equitable‐committees rules, using two well‐known properties: strategy‐proofness and equal treatment of equals. Our family contains as a special case the consent rules (Samet & Schmeidler. J. Econ. Theory, 110 (2003), pp. 213–233), which are symmetric and embody various degrees of liberalism and democracy; and it also includes dictatorial and oligarchic rules that value agents’ opinions differently. In the presence of strategy‐proofness, efficiency turns out to be equivalent to non‐degeneracy (i.e., any agent may potentially be included or excluded from the group). This implies that a rule satisfies strategy‐proofness, efficiency, and equal treatment of equals if, and only if, it is a non‐degenerate voting‐by‐equitable‐committees rule.
