Number of portfolios held by party, number of portfolios held by coalition, date of government formation, duration of coalition (in days) predicted kernel (i.e. payoff prediction notion, similar to the bargaining set, developed for games with transferable value), payoff, kernel payoff in coalition, number of parties in coalition.
