Comparing Presidential and Parliamentary Veto Powers in Legislative Bargaining
Quick fact
In a presidential system, the president can veto an entire bill and force a supermajority to override, but in a parliamentary system, the 'veto' is not a single actor—any coalition partner can threaten to withdraw support and collapse the government, making bargaining intensely coalition-dependent.
Why this is interesting
Think of a president who can single-handedly kill a bill, and a parliament where a small party can bring down the government. Why do they behave so differently in bargaining?
