introducing communication into this setting reduces strategic delay. We implement our model in a laboratory experiment utilizing a … experiment, while coordination failures emerge in the following periods sweeping away the beneficial effect of communication at … others creating socially suboptimal outcomes. We investigate if and how communication mitigates the strategic delay in …

We give an overview of the most common … models of communication and hierarchy restrictions in cooperative games, compare different network structures with each other … and discuss network structures that combine communication as well as hierarchical features. Throughout the survey, we …
