On the Coincidence of the Feedback Nash and Stackelberg Equilibria in Economic Applications of Differential Games
2002
In this paper the scope of the applicability of the Stackelberg equilibrium concept in differential games is investigated. Firstly, conditions for obtaining the coincidence between the Stackelberg and Nash equilibria are defined in terms of the instantaneous pay-off function and the state equation of the game. Secondly, it is showed that for a class of differential games with state-interdependence both equilibria are identical independently of the player being the leader of the game. A survey of different economic models shows that this coincidence is going to occur for a good number of economic applications of differential games. This result appears because of the continuous-time setting i…
Dynamic Models of International Environmental Agreements: A Differential Game Approach
2012
This article provides a survey of dynamic models of international environmental agreements (IEAs). The focus is on environmental problems that are caused by a stock pollutant as are the cases of the acid rain and climate change. For this reason, the survey only reviews the literature that utilizes dynamic state-space games to analyze the formation of international agreements to control pollution. The survey considers both the cooperative approach and the noncooperative approach. In the case of the latter, the survey distinguishes between the models that assume binding agreements and those that assume the contrary. An evaluation of the state of the art is presented in the conclusions along w…
Cooperación condicional y tercer sector
2000
The following paper analyzes the problem of social cooperation in the provision of a public good from an evolutionary perspective. To this end we depart from behavioral programs as the basic building block for modeling individuals in the social interaction, which is based on a generalized prisoners dilemma. In it, a population of individuals follow a conditional cooperative program, which some authors refer as to morality, and that we will show that is equivalent to the application of the principle of reciprocity. It will be shown that the degree of cooperation, that is the individual contribution toward the provision of the public good, is positive although sub-optimal. Finally, if we comp…
Reciprocity, matching and conditional cooperation in two public goods games
2005
Previous experimental and empirical evidence has identified social preferences in the voluntary provision of public goods. A number of competing models of such preferences have been proposed. We provide evidence for one model of behavior in these games, reciprocity (or matching, or conditional cooperation). Consistent with previous research, we find that participants in the voluntary contribution mechanism attempt to match the contributions of others in their group. We also examine participants in a related game with different equilibria, the weakest-link mechanism. Here, in contrast, participants contribute so as to match the minimum contribution of others in their group.
An experimental analysis of team production in networks
2010
Experimental and empirical evidence highlights the role of networks on social outcomes. In this paper we test the properties of exogenously fixed networks in team production. Subjects make the same decisions in a team-work environment under four different organizational networks: The line, the circle, the star, and the complete network. In all the networks, links make information available to neighbors. This design allows us to analyze decisions across networks and a variety of subjects’ types in a standard linear team production game. Contribution levels differ significantly across networks and the star is the most efficient incomplete one. Moreover, our results suggest that subjects act a…
El sector no lucrativo desde el enfoque de la elección pública: Cuando la oferta no lucrativa de bienes públicos es el resultado de decisiones emanad…

The voluntary supply of collective goods by nonprofit institutions has deserved little attention in the Public Choice literature, and the clasical nonprofits approach does not consider nonprofits supply as a collective decision, although individuals, either as consumers or as donors, are in the center of their theoretical constructs. In this paper we hypothesize that voluntary nonprofits' provision is a collective choice. We present a model in which the members of a community, both those who fund the nonprofits and those who do not (free riders) vote, so choosing between a political program of governmental supply and a political program of non governmental supply. Afterward, they must also …
