Fairness versus Efficiency
نویسندگان
چکیده
Fairness is a strong concern as shown by dictator and ultimatum experiments. Efficiency, measured by the sum of individual payoffs, is a potentially competing concern in games such as the prisoners’ dilemma. In our experiment participants can increase efficiency by gift giving. In the one-sided treatment this is only possible for one of the two partners. The two-sided treatment allows for mutual gift giving. In both cases decisions can be conditioned on whether there is or there is not an efficiency gain by gift giving. Our results indicate that efficiency concerns are dominated by fairness concerns that are less stringent in mutual exchanges than in one-sided gift-relationships.

Does procedural fairness crowd out other - regarding concerns ? A bidding experiment
Bidding rules that guarantee procedural fairness may induce more equilibrium bidding and moderate other-regarding concerns. In our experiment, we assume commonly known true values and only two bidders to implement a best-case scenario for other-regarding concerns. The two-bytwo factorial design varies ownership of the single indivisible commodity (an outside seller versus collective ownership) ...

In Fairness versus Welfare, we advance the thesis that social policies should be assessed based entirely on their effects on individuals’ well-being. This thesis implies that no independent weight should be accorded to notions of fairness (other than many purely distributive notions). We support our thesis in three ways: by demonstrating how notions of fairness perversely reduce welfare, indeed...
متن کاملClasses, Priorities and Fairness in Queueing Systems
Customer classification and prioritization are commonly used in many applications to provide queue preferential service. Their influence on queuing systems has been thoroughly studied from the delay distribution perspective. However, the fairness aspects, which are inherent to any preferential system and highly important to customers, have hardly been studied and not been quantified to date. In...
متن کاملFairness Considerations in Multi-Server and Multi-Queue Systems
Multi-server and multi-queue architectures are common mechanisms used in a large variety of applications (call centers, Web services, computer systems). One of the major motivations behind common queue operation strategies is to grant fair service to the jobs (customers). Such systems have been thoroughly studied by Queueing Theory from their performance (delay distribution) perspective. Howeve...
متن کاملBalancing Fairness and Efficiency in Repeated Societal Interaction
Fairness and efficiency are important aspects that influence cooperation in social dilemmas. During a repeated interaction, they have the potential to serve as competing goals for the decision maker. The ability to balance between fairness and efficiency depends, among other things, on available information regarding mutual accountability for the outcomes in an interaction. In this paper, we ex...
