/**
 * Policy Response System
 *
 * Models how governments respond to policy stimuli
 *
 * Research Foundation:
 * - COVID-19 response times: 10x acceleration for existential threats
 * - Boin et al. (2020): The Transboundary Crisis - government response to pandemic
 * - Lodge & Wegrich (2014): The Problem-Solving Capacity of the Modern State
 *
 * Response Time Formula:
 * ResponseTime = BaseTime × CrisisMultiplier × CapacityMultiplier × CoalitionDrag
 *
 * Where:
 * - BaseTime: Government type baseline (24-60 months)
 * - CrisisMultiplier: 0.1-1.0 (10x faster for existential crises)
 * - CapacityMultiplier: 0.6-1.4 (state capacity effect)
 * - CoalitionDrag: 1.0-2.0 (multi-party coalitions slower)
