Climate change in game theory context

The aim of this paper is to survey the game theory modelling of the behaviour of global players in mitigation and adaptation related to climate change. Three main fields are applied for the specific aspects of temperature rise: behaviour games, CPR problem and negotiation games. The game theory instruments are useful in analyzing strategies in uncertain circumstances, such as the occurrence and impacts of climate change. To analyze the international players’ relations, actions, attitude toward carbon emission, negotiation power and motives, several games are applied for the climate change in this paper. The solution is surveyed, too, for externality problem

Climate change in game theory

The study provides an overview of the application possibilities of game theory to climate change. The characteristics of games are adapted to the topics of climate and carbon. The importance of uncertainty, probability, marginal value of adaptation, common pool resources, etc. are tailored to the context of international relations and the challenge of global warming

Applications of Negotiation Theory to Water Issues

The purpose of the paper is to review the applications of non-cooperative bargaining theory to water related issues – which fall in the category of formal models of negotiation. The ultimate aim is that to, on the one hand, identify the conditions under which agreements are likely to emerge, and their characteristics; and, on the other hand, to support policy makers in devising the “rules of the game” that could help obtain a desired result. Despite the fact that allocation of natural resources, especially of trans-boundary nature, has all the characteristics of a negotiation problem, there are not many applications of formal negotiation theory to the issue. Therefore, this paper first discusses the non-cooperative bargaining models applied to water allocation problems found in the literature. Particular attention will be given to those directly modelling the process of negotiation, although some attempts at finding strategies to maintain the efficient allocation solution will also be illustrated. In addition, this paper will focus on Negotiation Support Systems (NSS), developed to support the process of negotiation. This field of research is still relatively new, however, and NSS have not yet found much use in real life negotiation. The paper will conclude by highlighting the key remaining gaps in the literature.Negotiation theory, Water, Agreeements, Stochasticity, Stakeholders

Asymptotic Efficiency in Stackelberg Markets with Incomplete Information

This paper examines the asymptotic (in)efficiency of Stackelberg markets with incomplete information. Firms who are early in the queue make their quantity choices based on limited information and their output choices are likely to deviate from those optimal under complete information. Due to the presence of both payoff externality and information externality, the output deviations of early firms have a lasting effect on all subsequent output decisions. Consequently, the total market output diverges from the competitive equilibrium output even as the number of firms goes to infinity. That is, Stackelberg markets with incomplete information are asymptotically inefficient with probability one. ZUSAMMENFASSUNG - (Asymptotische Effizienz in Stackelberg-Märkten mit unvollständiger Information) In diesem Beitrag wird die asymptotische (In-)Effizienz von Stackelberg-Märkten mit unvollständiger Information untersucht. Unternehmen, die frühzeitig auf den Markt kommen, bestimmen ihre Ausbringungsmengen unter unvollständiger Information. Aus diesem Grunde sind ihre Mengenentscheidungen im allgemeinen verschieden von den optimalen Ausbringungsmengen unter vollständiger Information. Auszahlungswirksame Externalitäten und Informationsexternalitäten bewirken, daß die Mengenentscheidungen der frühzeitig auf den Markt treffenden Unternehmen zu pfadabhängigen Mengen -entscheidungen nachfolgender Unternehmen führen. Im Ergebnis ist dann die gesamte Ausbringungsmenge aller Unternehmen verschieden von dem Konkurrenzgleichgewicht - selbst dann, wenn die Anzahl der Unternehmen gegen unendlich strebt. Das heißt, Stackelberg- Märkte mit unvollständiger Information sind asymptotisch ineffizient mit der Wahrscheinlichkeit eins.

A METHOD FOR STRATEGIC DECISION MAKING IN A WATERSHED -GAME THEORY

Rapid growth of urban areas and their development problems in industrializing countries has had major impacts on the environment. Water, the main source of life on earth is under the threat of various types of pollution. These threats have been forceful in demonstrating the necessity of the management and planning of drainage basins. The importance of the evaluation of the total economic value of the water resources and aquatic ecosystems of drainage basins has not yet been accepted in the current planning system of Turkey. In Turkey a total number of 36 public agencies take part in the decision making process within a drainage basin. Decisions taken by these agencies with respect to the use of land and water affect the quality and sustainability of water as a natural resource. These agencies act under a legal structure comprising 105 different laws and regulations related to the environment and this creates additional confusion in planning practice. The situation calls for the organization of special drainage management institutions for drainage basins. The aim of this study is to explore the use of game theory to analyze the roles and actions of different interest groups (players) and develop a better understanding of the decision making process and its consequences on a drainage basin. In this study, we use the case of a river sub-basin from the north-western region of Turkey: the Nilüfer Watershed that contains fertile agricultural lands and the third biggest industrial city in Turkey. The Nilüfer Stream is deeply polluted by industrial, agricultural and domestic wastewater. There are 1 metropolitan municipality, 20 district municipalities and 8 provincial authorities of central government within the watershed. All players have strategies about environment and planning such as land use decision, waste water standard and discharge permitting etc. Some strategies conflict the other players’ strategies. Game theory, which aims to explain the interactive decision making process with more than one decision maker, has developed as a theory of human strategic behavior based on an idealized picture of rational decision making (Binmore, 1996; Eichberger, 1992). The game theory has been applied to social sciences especially to economy, international relations, politics, which are in the state of making decisions in non-cooperative conditions. Although there is limited in number the game theory applications in planning, they are very important studies on location problem in spatial planning such as Stevens, (1961), Isard and Reiner, (1962), Isard, (1967). There are also new studies that use the game theory in planning. Sharing problem of river as a natural resource is the main study area in planning (Dinar and Wolf, 1994; Kilot, 1994; Kucukmekmetoglu and Guldman, 2002; Rogers, 1993). Game theory applications on environmental problems started in 1990s. Environmental problems such as transfrontier pollution (air or water) are often multilateral, and they affect all the agents in the economies of countries. There are studies in which air pollution problem is analyzed by the game theory with the cooperation of neighbor countries such as Ray (2000), Maler and Zeeuw (1998), Barret (1998). In this research an in depth analysis is made to understand the preferences and attitudes of different players taking part within the Nilüfer watershed. Players generally make independent decisions without any form of cooperation situation. Therefore, non-cooperative game is used in this analyze. The decision making process of the players are analyzed through a scenario in two-player games. The scenario is about strategies of environmental protection and industrial development in the watershed. We explore Nash equilibrium in game which represents present condition. Nash (1950) proved the existence of a strategic equilibrium for non-cooperative games. The main outcome of the paper will be to point to new directions in the planning process and to open to discussion the use of game theory in planning. Game theoretic approach will make it easier for the agents to cooperate if the conflicts in the planned area are clearly defined. It is possible to achieve cooperative bargaining solutions where all agents are winners. Actually, this is the target of planning because sustainable development of the river basin depends on bargaining where all agents are winners.

Essential Feature - Cooperative Gameplay

Although single player and multiplayer is very important in today game, cooperative mode is an essential part of a great game. There are a lot of benefits of playing co-op mode in a game such as education and joy. Communicating, solving problems, handling stress, managing time, making decision, following instructions, acting fast as well as working in a team are skills that students can learn and practice while they are playing cooperative games. These skills are valuable for students to use in education and even in careers

The Puzzle of Social Preferences

We present a brief overview of the experimental economics literature on social preferences. In numerous experiments, economically incentivized subjects are willing to sacrifice part of their material earnings to compensate the kind behavior of others, or will be willing to reciprocate at a non-negligible cost, or even pay a positive price for punishing the behavior of selfish individuals. All these actions are labeled as social in economics because there is no apparent way to reconcile them with any reasonable form of pure self-interest. We focus on social dilemma games and want to communicate two main messages. First, research in experimental economics has produced abundant evidence that illustrates the social components of people’s preferences. Second, social sanctions of different types play an important role in facilitating cooperative behavior.
