The Basic Arithmetic of Legislative Decisions was authored by Michael Laver and Kenneth Benoit. It was published by Wiley in AJPS in 2015.

What is Legislative Arithmetic?

This paper examines the surprisingly straightforward numerical factors that underpin legislative decision-making processes.

Legislative Behavior Analysis

The authors demonstrate how basic arithmetic principles can explain seemingly complex political behaviors in modern legislatures. By quantifying various elements of legislative composition, this research uncovers fundamental patterns governing voting behavior and outcomes.

Key Findings

The study finds:

  • Simple numerical compositions significantly influence majority/minority dynamics
  • Quantitative models better predict legislative success rates than traditional qualitative approaches
  • Basic arithmetic principles can explain the formation of policy majorities across diverse political systems worldwide

Real-World Significance

The findings offer new insights for scholars studying descriptive representation and voting behavior. For policymakers, understanding these fundamental numerical drivers may improve legislative strategy design.
