This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within...

This chapter critically analyses contributions to evolutionary game theory by such writers as Robert Trivers, John Maynard-Smith, and Robert Axelrod. It develops four key arguments. First, that the behavioral propensities that manifest themselves in altruistic behavior are empirically relevant,...

This paper represents the third part of a research work dealing with the integration of economic efficiency and equity considered as a no-envy concept. Specifically, I examine here the problem of reduction of the malicious envy in a cultural evolutionary context. In fact, both in the case of...

I study the incentives of Cournot duopolists to share their technologies with their competitor in markets where intellectual property rights are absent and imitation is costless. The trade-off between a signaling effect and an expropriation effect determines the technology-sharing incentives. In...

Intergenerational altruism and contemporaneous cooperation are both important to the provision of long-lived public goods. Equilibrium climate protection may depend more sensitively on either of these considerations, depending on the type of policy rule one examines. This conclusion is based on...

We investigate a setting in which members of a population, bifurcated into a majority and a minority, transact with randomly matched partners. All members are uniformly altruistic, and each transaction can be carried out cooperatively or through a market mechanism, with cooperative transactions...

We examine two types of altruism and their implications for voluntary giving. Philanthropists are altruists who wish to enhance the well-being of others, while individuals with merit-good preferences only wish to further the consumption of certain merit goods by others. Philanthropic donors...

We analyze the role of "the" utility discount rate and its implications to generation-specific and societal altruism and egoism, respectively, in a neoclassical framework. It is worked out clearly, that two different utility discount rates have to be distinguished: An (inverse)...

The future effects of climate change may induce increased intergenerational altruism. But will increased intergenerational altruism reduce the threat of climate change? In this chapter we investigate this question. In a second-best setting with insufficient control of greenhouse gas emissions in...

Recognizing that individualism, or weak family ties, may be favorable to economic development, we ask how family ties interact with climate to determine individual behavior and whether there is reason to believe that the strength of family ties evolves differently in different climates. For this...
