Are Bus Fares Elastic or Inelastic?

Price Elasticity of Bus Fares: It Depends

Bus fare elasticity varies by context, time horizon, and rider demographics.

Elastic Scenarios

• Short-term, discretionary riders: Small fare hikes may shift some to walking, cycling, carpooling.
• Long-term: Riders adjust—move closer to work, change jobs, buy cars—increasing elasticity over time.
• Good substitutes exist: Rail, rideshare, biking infrastructure.

Inelastic Scenarios

• Transit-dependent riders: Low-income, students, elderly, carless—few alternatives, must ride regardless of fare.
• No competition: Monopoly service in area.
• Employer-subsidized passes: Rider insensitive to price.

Key Factors

• Availability/affordability of alternatives
• Transit network quality
• Income levels
• Trip purpose (commute vs. discretionary)

Studies typically find short-run elasticity of -0.2 to -0.5 (inelastic), long-run -0.6 to -1.0 (more elastic).
