Tiebout Sorting

Swap households between two towns and compare service fit with the cost of moving.

PLAY & EXPLAIN

Each town has two homes and a tax of 2 per household. Park lovers P value Park at 10 and Quiet at 3; quiet lovers Q value them at 4 and 8. Town services and taxes stay fixed.

08
Park
Quiet
Benefits after taxes
17
Moving costs paid
0
Net after moves
17

Both communities remain full. The initial benefits total 17; matching both P households to Park and both Q households to Quiet gives 28 before moving costs. Sorting is not a fairness measure.

Services, taxes and capacity are fixed; sorting benefits do not establish fairness or account for exclusion, externalities or unequal mobility.

THE SHORT VERSION

Tiebout Sorting, explained.

Tiebout sorting is the idea that residential choices among local jurisdictions can reveal preferences for different bundles of public services and taxes under demanding assumptions.

01 / THE MECHANISM

Why it happens

Two two-home towns have fixed benefits and taxes. Park-preferring and quiet-preferring households can swap places, preserving capacity. Aggregate benefits after tax are reduced by explicitly accumulated moving costs.

Tiebout sorting is the idea that residential choices among local jurisdictions can reveal preferences for different bundles of public services and taxes under demanding assumptions.

Read the result

Gross benefits after tax and moving-cost-adjusted benefits are displayed separately, with capacity fixed at two homes per town.

02 / FOLLOW IT THROUGH

A worked example

Improve fit without creating extra homes

  1. Start with one park lover and one quiet lover in each of the two towns.

  2. With zero moving cost, swap the misplaced households to raise aggregate benefits from seventeen to twenty-eight.

  3. Reset with moving cost six and perform the same two-household swap; net benefits become sixteen, below the initial seventeen.

OPTIONAL DEEPER DETAILGo deeper: inside the model

Inside this model

Two two-home towns have fixed benefits and taxes. Park-preferring and quiet-preferring households can swap places, preserving capacity. Aggregate benefits after tax are reduced by explicitly accumulated moving costs.

03 / BEYOND THE EXPERIMENT

Where this idea is useful

A practical use

Ask whether relocation is genuinely available before assuming people can simply choose a better-fitting public-service bundle.

CHECK YOUR INTUITION

A common misconception

THE TEMPTING CONCLUSION

“Better residential fit makes any move socially beneficial.”

THE MORE USEFUL DISTINCTION

Mobility costs can outweigh the fit gain, and aggregate benefits omit distribution, exclusion and externalities even when the arithmetic improves.

What this explanation leaves out

  • Services, taxes and capacity are fixed; sorting benefits do not establish fairness or account for exclusion, externalities or unequal mobility.
ONE MORE QUESTION

Are service bundles funded endogenously here?

No. Taxes and benefits are fixed to isolate preference fit and moving costs; the activity is not a complete local-public-finance model.
