This paper investigates the possibility of signal jamming in games with multiple informed parties whose interests are conflicting. The possibility that signal jamming occurs in equilibrium depends on the observability of individual signals. Paradoxically, if the receiver can observe individual...

We introduce a new notion of connectivity, what we call weak connectivity, in a directed network where communication is one-way, and show that weak connectivity is equivalent to the usual concept of connectivity if the outdegree of each node is at most one, referred as the [DC] condition. Based...
