Reputational incentives depend on the specification of market learning. When consu...

In an environment in which free-riders are better off than cooperators, social control is required to foster and maintain cooperation. There are two main paths through which social control can be applied: punishment and reputation. Our experiments explore the efficacy of punishment and reputation on cooperation rates, both in isolation and in combination. Using a Public Goods Game, we are inter...

Traditional trustworthy service selection approaches focus the overall reputation maximization of all selected services in social networks.
