作为内生偏好的利他行为及其经济学意义

现代经济学与现代生物学对人性的看法相当一致,都把自利看作人类行为的基本前提。但来自桑塔费学派的最新研究证明,在人类进化的早期阶段,利他行为作为社会规范内部化的产物,在维持个人之间的合作劳动、有效提高族群生存竞争能力方面,具有不可替代的重要作用。我们在ESS(即“进化稳定策略”)基础上提出一个演化均衡模型,进一步解释了利他行为的进化优势以及合作剩余导致利他偏好内生的机制。     

Calling party pays or receiving party pays? The diffusion of mobile telephony with endogenous regulation

This paper analyzes the impact on mobile telephony diffusion patterns of the two predominant payment regimes, calling party pays (CPP) and receiving party pays (RPP), for mobile termination services. By applying instrumental variable techniques to panel data we account for a possible interdependency of penetration rates and regulatory interventions. For this purpose we use data on political and institutional factors to instrument endogenous regulatory decisions. We conclude from our empirical analysis that there is no significant impact of either RPP or CPP on penetration rates. Therefore an application of RPP in order to obviate regulation of termination fees would be feasible.     

Why it pays for aid recipients to take note of the Millennium Challenge Corporation: Other donors do!

We empirically analyze how other aid agencies, within and outside the United States, reacted to the Millennium Challenge Corporation (MCC). We find that positive signaling effects dominate possible substitution effects. Striving for MCC eligibility thus pays.     

创造性资本主义与资本主义的创造性消亡

资本主义具有一种内生的创造性,同时又具有一种内生的非创造性,创造性和非创造性悖论根源于资本主义经济的内在矛盾。随着世界市场的不断成熟和全球资本主义经济矛盾的不断加深,资本主义需要寻求新的自我拯救之道。创造性资本主义试图同时利用人性中的利己主义与利他主义。创造性资本主义预示着资本主义终将创造性地消亡,它对未来中国社会主义市场经济体制改革具有重要的启发意义。     

Group Selection and the Limits to Altruism

Several evolutionary mechanisms have been identified in the literature that would generate altruism in humans. The most powerful (except for kin selection) and most controversial is group selection, as recently analyzed by Sober & D.S. Wilson. I do not take a stand on the issue of the existence of group selection. Instead, I examine the level of human altruism that could exist if group selection were an engine of human evolution. For the Sober & Wilson mechanism to work, groups practicing altruism must grow faster than other groups. I call altruistic behavior that would lead to faster growth efficient altruism. This often consists of cooperation in a prisoner's dilemma. ltruistic acts such as helping a temporarily hungry or injured person would qualify as efficient altruism. Efficient altruism would also require monitoring recipients to avoid shirking. Utilitarianism would be an ethical system consistent with efficient altruism, but Marxism or the Rawlsian system would not. Discussions of efficient altruism also help understand intuitions about fairness. We perceive those behaviors as fair that are consistent with efficient altruism. It is important to understand that, even if humans are selected to be altruistic, the forms of altruism that might exist must be carefully considered and ircumscribed.     

开源经济的现代价值分析

开源经济是基于开源软件基础上发展起来的一种新的生产方式,它之所以受到学界的关注是因为开源经济对现有的西方经济学理论提出了严峻的挑战:参与者利己与利他双重行为倾向违背了西方经济学的经济人假设;开源经济的生产组织方式和治理机制相比传统企业制度在某些方面表现出显著的高效性;开源软件生产克服了公共物品供给的难题等。但是,开源经济与马克思主义的社会主义经济学却具有很强的一致性。开源经济的研究对于在现时检验和发展马克思主义经济学具有重要的理论价值。     

Altruism and the Economic Values of Environmental and Social Policies

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population.     

Religion and the sociological critique of political economy: Altruism and gift

Abstract

This article shows that there is a strong connection between the religious component of French sociology and the critique of political economy. In the first section, I consider how selfish behaviour, or egoism, became treated as a major threat endangering the creation of industrial society by those concerned about the diffusion of political economy. I then summarise the methodological critique set forth in the Cours, before connecting this critique to the economic content of the Système and the concept of altruism. In the following section, Spencer's view of altruism is contrasted to that held by Comte, and then I consider the reaction of French political economists, defending the moral value bought about by their science. In the final section, I explain how the Comtean approach was re-enacted by Durkheim and then by Mauss, at the head of the “sociology of religion” section of L'Année sociologique, the Durkheimian journal, to give birth to the theory of gift-giving behaviour that Mauss used to critique political economy in the 1920s.     

Cooperation without Reputation: Experimental Evidence from Prisoner's Dilemma Games

This paper investigates cooperative play in prisoner's dilemma games by designing an experiment to evaluate the ability of two leading theories of observed cooperation: reputation building and altruism. We analyze both one-shot and finitely repeated games to gauge the importance of these theories. We conclude that neither altruism nor reputation building alone can explain our observations. The reputation model is inconsistent with play in both one-shots and finitely repeated games while the model with altruism is unable to explain observed play in the finitely repeated games.Journal of Economic LiteratureClassification Numbers: C72, C92.     

Pay-what-you-want in groups – evidence from a field experiment

Pay-what-you-want (PWYW) mechanisms are a specific form of voluntary market payment. While a large number of recent studies have considered their design options, the aspect of group behaviour in PWYW situations has not been investigated, although a substantial part of payment decisions occur in group constellations. We provide initial evidence by running a field experiment implementing a PWYW mechanism in a cinema characterized by group attendance, finding that groups chose to pay similar amounts as individuals. Group payments can be increased by a prosocial framing of the decision, while an increase in group size and repeated participation reduce voluntary payments. We thus show that group payment decisions in PWYW situations are characterized by altruism concerns rather than in-group egoism.     

继任博弈及其在企业中的应用

继任博弈是一个新概念,它关注的是在任者如何决定留下多少贡献给继任者。企业中的继任博弈存在留下贡献(产出)占个人总贡献的比例为常数的均衡策略,但其通常和总产出最大化的条件有差异。这可以为个人努力的差异性、短视行为、企业中的利他行动提供不足提供新的解释。当参与人只存在一期,不同类型的参与人留下产出的量不同,并可能存在贝叶斯均衡策略。在家族企业继任博弈中,参与人的效用函数因亲缘关系而改变并使参与人对继任者能力要求降低,导致低能力的继任人缺乏提高生产能力的动力。     

Detecting motives for cooperation in public goods experiments

This study clarifies the types of motives that are important as a source of cooperation in a linear public goods experiment. Our experimental design separates contributions into those due to confusion, one-shot motives (which includes altruism, warm-glow, inequality aversion, and conditional cooperation), and multi-round motives (which includes a strategic motive under incomplete information, a failure of backward induction, and reciprocity). The experiment reveals that multi-round motives plays an important role in driving cooperative behavior. Confusion and one-shot motives play a minor role.

The difficulties of "polluter pays" policy in agricultural pollution in UK and methods to improve it

Agricultural wastes pollution became serious after great improvement in technology and the encouragement of production for the government since the end of the World War Ⅱ. Economists and environmental scholars suggested that "polluter pays" policy be employed in agricultural pollution control. However, it was hard to implement "'polluter pays " policy alone in agricultural wastes pollution. In practice, there were two social factors which contributed to the improvement of water quality in the southwest of United Kingdom. One method is to communicate with farmers and then give farmers some advice or exhortation on facilities and management. The other method is to get up a telephone hotline for public to report water quality and probable pollution. Therefore, the consideration and combination of social factors in the control of agricultural wastes pollution are necessary and important. Education of basic natural sciences relevant to agricultural pollution, system management of agricultural pollutants and laws relevant to agricultural pollution is suggested to be the third social factor that British government can consider.     

How do altruistic parental transfers affect the welfare gains of marriage?

This paper analyses the effects of altruistic parental transfers on the welfare gains of marriage. To that end, it develops a sequential game which, in a first stage, determines the optimum level of the transfer between the altruistic donor (the parent) and the recipient (the daughter/son). In the second stage, the levels of consumption and provision of a family good are deduced by way of a Nash bargaining solution, with the threat point being represented by divorce. We find that the degree of altruism of the recipient has a null effect on the gains in welfare derived from the marriage by the recipient’s spouse, and a positive effect on those derived by the recipient. Additionally, the degree of altruism of the donor has a positive effect on the gains in welfare derived from the marriage by the recipient’s spouse, and an ambiguous effect on those derived by the recipient.

Malnutrition and Child Labor

In pre‐industrial and developing economies, it is common to find (i) entire families, including children, working together in family farms or urban factories; and (ii) a positive link between a person's consumption and her productivity. This paper argues that there is a natural reason for the concurrence of (i) and (ii). As a rule, households are characterized by intra‐household altruism: an increase in the income of an individual increases the consumption of all household members. Hence, when an employer pays an adult worker a high wage to enhance her productivity, part of it ends up augmenting her children's consumption and productivity. One way for the employer to prevent this leakage and internalize the externality is to employ the children as well. This explains the higher incidence of family labor in poor societies where (ii) is more likely to be true.     

Friendship,not altruism: an economic theory with cross-cultural applications

Friendship is both ubiquitous and economically important, but neglected in the economic literature. We provide a definition of friendship supported by anthropology research that we believe is plausible, widely accepted, and distinct from altruism. This motivates a game-theoretic model of friendship that provides a characterization of how friendship in a bilateral relationship can explain cooperation in a finite-horizon setting without the aid of altruism or pro-social preferences. We highlight the difference between two key equilibria of our model: opportunistic friendship that is short-lived and driven by material support, and sustained friendship that is long-lived and is distinguished from opportunistic friendship by the provision of support without the expectation of return. Opportunistic friendship seems more likely in environments characterized by economic uncertainty such as in developing countries or immigrant communities. We provide cross-cultural examples of friendship that are consistent with the conditions underpinning opportunistic versus sustained friendship equilibria.     

Freedom, enforcement, and the social dilemma of strong altruism

Cooperation in joint enterprises poses a social dilemma. How can altruistic behavior be sustained if selfish alternatives provide a higher payoff? This social dilemma can be overcome by the threat of sanctions. But a sanctioning system is itself a public good and poses a second-order social dilemma. In this paper, we show by means of deterministic and stochastic evolutionary game theory that imitation-driven evolution can lead to the emergence of cooperation based on punishment, provided the participation in the joint enterprise is not compulsory. This surprising result—cooperation can be enforced if participation is voluntary—holds even in the case of ‘strong altruism’, when the benefits of a player’s contribution are reaped by the other participants only.     

A theory of gender differences in parental altruism

Abstract.  We offer a theory of gender differences in parental altruism based on the asymmetry that female fertility is constrained but male fertility is relatively unconstrained. Modelling human preferences as having been shaped during the Pleistocene, we derive evolutionarily stable, co‐evolved male and female preferences for altruism towards one's children. We demonstrate that there would be gender differences in parental altruism that depend on the relative abundance or scarcity of resources and the importance and substitutability of parental inputs in promoting the survival of offspring. The results point to greater altruism in females, under plausible conditions. JEL Classification: D64, J16, P46
