About This Template
Analyze public goods provision decisions and free rider problems with this interactive Public Goods Free Rider Calculator Excel template. Built for economics students, public policy analysts, and educators, this spreadsheet applies core microeconomic principles from Mankiw Chapter 11 to real-world cost-benefit scenarios.
What You Can Calculate
This template computes all the key metrics for public goods analysis:
- Total Social Benefit (TSB) — The sum of all individual valuations, representing society's total willingness to pay
- Net Social Benefit (NSB) — Whether providing the good creates positive value (TSB minus Cost)
- Provision Decision — Clear Yes/No/Break-Even recommendation based on cost-benefit analysis
- Free Rider Count — Identifies which participants would benefit without paying their fair share
- Voluntary Provision Analysis — Shows the funding gap when relying on voluntary contributions alone
Required Inputs
Enter just two types of data to get complete results:
- Cost of Public Good — The total funding required to provide the good
- Individual Valuations — Each person's maximum willingness to pay (supports up to 10 people)
Methodology
The calculator uses standard public economics formulas: TSB equals the sum of individual valuations, and provision is recommended when TSB exceeds or equals Cost. Free riders are identified by comparing each person's valuation to their equal cost share (Cost/N). The voluntary provision analysis shows why public goods often require government intervention — even when total benefits exceed costs, free riding creates funding gaps.
Assumptions and Limitations
- Assumes equal cost sharing among participants
- Free riders defined as those with valuations below equal share
- Supports up to 10 people (expandable by editing formulas)
- Does not model Lindahl pricing or alternative funding mechanisms
Frequently Asked Questions
The template supports up to 10 people by default. For larger groups, unprotect the Calculator sheet, add more valuation rows, and update the formulas to include the new cell range (e.g., change val_10 to val_20).
Simply leave unused valuation cells blank or set them to zero. The template automatically excludes zero-value rows from all calculations, so only populated rows count toward the number of participants.
The template uses equal cost sharing by default. To model alternative schemes like proportional sharing or Lindahl pricing, unprotect the sheet and modify the equal_share formula and downstream calculations.
