The Tax Abatement That Looked Free
A Georgia county commission is considering a 10-year property-tax abatement for a distribution center. The company promises 300 jobs and a $40 million investment. The county's current property-tax revenue is $12 million a year. Staff estimate the abatement would forgo $6.8 million over 10 years; road upgrades would cost $3.2 million. The company says average pay is $17 an hour. The commission chair says, 'There is no cost to taxpayers-it is just forgone revenue.' A student group has four minutes to present at a public hearing and must use economic reasoning, not opinion. The county's median hourly wage is $19.50, and the unemployment rate is 4.1 percent.
1. Identify the chair's economic reasoning error and explain the relevant concepts the students should use.

The error is treating forgone revenue as costless. Forgone property tax is an opportunity cost because the county gives up public revenue it could have spent on schools, roads, or other services. Students should use marginal analysis: compare the additional benefits, such as new tax base after the abatement, wages, and indirect jobs, with the additional costs, such as the abatement, road upgrades, and added services. They should ask about net new jobs versus displacement, since 300 jobs may not all be new if workers leave other local employers. They should consider tax incidence: who actually bears the tax and who receives the abatement. They should also note externalities such as traffic and infrastructure, and state the counterfactual: what would happen without the deal? The phrase no cost is politically appealing but analytically false.
2. Build a cost-benefit framework with at least three data needs and one caveat. Explain how each item changes the conclusion.

First, calculate the net present value of forgone taxes versus projected new taxes over 10 years; the discount rate matters because $6.8 million spread over a decade is not the same as a lump sum. Second, assess job quality by comparing $17 per hour with the county median of $19.50 and estimating how many workers are local and previously unemployed; if most are commuters or displaced, net local benefit falls. Third, include infrastructure and services: $3.2 million for roads plus added school and emergency costs are real costs. Fourth, estimate the counterfactual value of the site without the abatement. A key caveat is that company projections are advocacy, not forecasts, so students should run a sensitivity analysis. The conclusion could change if net new jobs are low or if the abatement exceeds new revenue.
3. How should the students present the issue without confusing positive and normative claims?
Read the worked answer
They should separate what is measurable from what is a value judgment. Positive claims include the abatement forgoes $6.8 million in property tax over 10 years, the road upgrade costs $3.2 million, and average pay is $17 per hour versus a $19.50 median. Normative claims include the county should prioritize schools over incentives, or attracting jobs is worth the cost. The students can present a decision rule: if net new local income and tax revenue exceed costs, the deal improves efficiency, but distributional effects still require a value choice. They should avoid saying taxpayers lose without specifying which taxpayers and over what period. A four-minute presentation should state assumptions, show a range, and recommend conditions such as clawbacks or wage standards. This demonstrates economic reasoning rather than advocacy.
