This paper studies an extensive form game of coalition formation with random proposers in a situation where coalitions impose externalities on other players. It is shown that an agreement will be reached without delay provided that any set of coalitions profit from merging. Even under this...

Multifractal analysis and extensive statistical tests are performed upon intraday minutely data within individual trading days for four stock market indexes (including HSI, SZSC, S&P 500, and NASDAQ) to check whether the indexes (instead of the returns) possess multifractality. We find that the...

This paper provides a methodology to study coalition formation problems with externalities and heterogeneous players, when some subset of the players can act as “coalition developers” over time. The framework provided here allows to explicitly predict the timing of admission to coalitions,...

We present a well-defined generalisation of the core to coalitional games with externalities, where the value of a deviation is given by an endogenous response, the solution (if nonempty: the core) of the residual game. Copyright Springer Science+Business Media, LLC 2007
