Comparing Legislative Systems
A systematic comparison of how laws are made in the US, UK, EU, and other democracies — identifying the key design choices that shape legislative outcomes.
The Design Choices That Matter Most
Every legislative system is a product of design choices — some deliberate, some accidental. The most consequential variables are: separation of powers (can the executive dissolve the legislature, or are they independently elected?), bicameralism (one chamber or two, and how powerful is each?), committee systems (standing committees with fixed jurisdictions or ad hoc committees?), party discipline (do members vote as individuals or as party blocs?), and executive veto power.
These choices interact. Strong party discipline plus parliamentary government equals fast legislation. Weak party discipline plus separation of powers plus bicameralism equals slow legislation. The US system combines weak discipline with separated powers and coequal chambers — producing the most veto points and the slowest legislative process of any major democracy.
