Causes of Stability in Dynamic Coalition Formation

We study the formation of stable outcomes via simple dynamics in cardinal hedonic games, where utilities agents change over time depending on history coalition process. Specifically, we analyze situations members a decrease their utility for leaving agent (resent) or increase joining (appreciation). show that contrast to classical dynamics, resentful appreciative agents, are guaranteed converge under mild conditions various stability concepts. Thereby, establish both resent and appreciation strong stability-driving forces.
