ABSTRACTCooperation in collective action dilemmas usually breaks down in the absence of additional incentive mechanisms. This tragedy can be escaped if cooperators have the possibility to invest in reward funds that are shared exclusively among cooperators(prosocial rewarding). Yet, the presence of defectors who do not contribute to the public good but do reward themselves(antisocial rewarding) deters cooperation in the absence of additional countermeasures. A recent simulation study suggests that spatial structure is sufficient to prevent antisocial rewarding from deterring cooperation. Here we reinvestigate this issue assuming mixed strategies and weak selection on a game-theoretic model of social interactions, which we also validate using individual-based simulations. We show that increasing reward funds facilitates the maintenance of prosocial rewarding but prevents its evolution from rare, and that spatial structure can sometimes select against the evolution of prosocial rewarding. Our results suggest that, even in spatially structured populations, additional mechanisms are required to prevent antisocial rewarding from deterring cooperation in public goods dilemmas.

Democratic Elections

The problem of dirty hands concerns the apparently inevitable need for effective politicians to do what is ethically wrong. This essay discusses a related problem in democratic elections of politicians being unwilling to commit themselves to precise positions on controversial policy issues. Given certain plausible assumptions, I demonstrate using a simple game theoretic model that there is an incentive structure for political candidates that is damaging to the public good. I contrast this problem with the classic prisoner’s dilemma and then go on to discuss some possible strategies for overcoming this problem by an improved system of political debates.

Game Theoretic Model

This paper examines Bain's Hypothesis that firms in the automobile industry engage in advertising competition and price collusion. It develops a game theoretic model, basing price on product characteristic and advertising on pure and mixed strategies. Solution concepts such as Cournot, Nash and Prisoner's dilemma are possible. The paper then moves into regression results of advertising outlays in newspaper, general magazines, spot television, and network television, given the firm's cashflow, OPEC influence, and Leader-follower hypotheses. When multicolinearity and serial correlation are adjusted for, the results corroborate Bain's advertising hypothesis with price collusion.

Drawing on empirical observations of operation of public distribution system in different states of India, the paper constructs a preliminary game theoretic model. It argues that an effective public distribution must be as universal as possible, delivery mechanism of fair price shops should be re-formed, they should be make them commercially viable and that special attention should be paid to PDS at times of high food inflation.

Optimal Mixed Strategies

In the paper we propose a simple game-theoretic model of a Desktop Grid for volunteer computing. Task replication reduces the risk of accepting wrong answers due to sabotage. Saboteur's attack by intruding multiple computing nodes brings him some profit in case a wrong answer is accepted, while the server suffers some penalty in this case. Nodes are assigned some reputation as a monotone function of the number of produced correct (or not exposed) answers. We obtain the optimal mixed strategies and show that the average gain of the players depends only on the server's penalty, nodes' reputation, and the size of the subgrid of nodes with the same reputation. Also we estimate the server's cost per an answer. Numerical examples show that the average cost of the server is not more than that in the case when the number of intruders is known.

Game Theoretic Model

Why are extremists able to sabotage peace processes in some cases but not others? And under what conditions will the public respond to such provocation and return to unpopular wars? We seek to show that extremist violence is not indiscriminate or irrational as many people have assumed but quite strategic. We argue that extremist violence intentionally plays on the uncertainty that exists between the more moderate groups who are attempting to negotiate a peace agreement. Using a game-theoretic model of the interaction of extremist violence and mistrust, we identify the conditions under which extremists will succeed and fail. We find that extremists are most likely to succeed in derailing a peace process when the targeted side believes that opposition moderates are strong. At these times, the public perceives moderates as best able to control and suppress extremists within their own ranks. When moderates are viewed as weak and unable to crack down on extremists, terrorism is more likely to fail. We discuss this finding, as well as a number of additional implications of the model, in connection with the Israeli–Palestinian case.

Informal Value Transfer System

Informal financial operations exist in the shadow of official regulation and cannot be protected by the formal legal instruments, therefore raising concerns about the enforcement of obligations taken by their participants. This paper analyzes two alternative types of auxiliary institutions, which can coordinate expectations of the members of informal value transfer systems, namely attitudes of trust and norms of social control. It offers some preliminary approaches to creating a game-theoretic model of partner interaction in the informal value transfer system. It also sheds light on the perspectives of further studies in this area of institutional economics.

The Impact

Strong labour laws play a major role in motivating innovation among employees. It has been found in the literature that stringency of labour laws is positively linked with employees’ efforts in innovation, in particular, wrongful discharge laws (WDL). However, employees may also bring nuisance suits against employers. Usually, the result of these suits is that both parties settle with each other. Thus, even if employees are justly dismissed, they may be able to bring nuisance suits against employers and gain a settlement amount. This article investigates how the possibility of nuisance suits affects the impact of WDL on employees’ efforts in innovation. In this respect, a game-theoretic model is developed in the article to find the equilibrium level of employees’ efforts in the presence of nuisance suits, where there is a possibility of employees getting discharged from the firm. I find that if nuisance suits are a possibility, the stringency of WDL has no impact on employees’ efforts if defence cost of the firm is low; but for higher defence costs, WDL affects employees’ efforts. The efforts exerted by an employee are found to be weakly increasing in the defence costs of the firm.
