摘要	The government formation model is a non-cooperative bargaining theory explaining how a cabinet and the division of its portfolios emerge when no party holds a majority. In the canonical Baron-Ferejohn (1989) framework, a head of state or chance mechanism recognizes one party as formateur with a probability often proportional to its seat share; the formateur proposes a government and an allocation of the spoils of office, and the proposal takes effect only if a legislative majority accepts. Austen-Smith and Banks (1988) embed this in an electoral and coalition setting. The model's signature result is a proposer (formateur) advantage: the party that gets to propose secures a disproportionate share of portfolios.	Veto player analysis is a spatial-institutional framework, developed by George Tsebelis in his 1995 article and 2002 book, for predicting the capacity of a political system to change policy. A veto player is any individual or collective actor whose agreement is required to alter the status quo. The theory shows that the potential for policy change shrinks as the number of veto players grows, as the ideological distance between them widens, and as their internal cohesion increases — three structural variables that together determine a system's policy stability independently of constitutional labels such as presidentialism or parliamentarism.
