Veto player theorem
The veto player theorem (also: veto player approach ) is a proposition from political science that tries to explain the possibility of changing political conditions depending on the behavior of the people involved - so-called veto players .
The political scientist George Tsebelis formulated the theorem on the basis of analyzes of existing political systems in which he claims that a departure from the status quo in political institutions is all the more likely.
- the smaller the number of powerful, acting persons ( veto players )
- the greater the agreement of the opinions of the veto players,
- the smaller the cohesion of the veto players,
- the greater the ideological difference to the previous government,
- the longer the government is in office.
