Water and development mattered more when a price was shown
New Zealand council members chose among hypothetical urban plans. Cultural impacts, described only in words, did not have a consistent effect.

The key idea
An impact with a visible price tended to matter more in the choice. Impacts described only in words did not have a consistent effect.
The study, in plain language
The survey presented urban expansion options with effects on development, water quality, and cultural heritage. Local council members and officials were, or were not, shown monetary values for certain effects before choosing.
Showing monetary values strengthened preferences for different levels of development and opposition to worsening water quality. Impacts described only in words, such as cultural effects, did not have a consistent influence. How information was presented changed some choices, all within hypothetical scenarios.
What they found
- Showing monetary values strengthened preferences for different levels of development.
- It also strengthened opposition to worsening water quality.
- Cultural impacts described only in words did not consistently influence choices.
Something to think about
When you look at a plan for your city, what matters to you beyond what can be expressed in money?
How they studied it
A choice survey presented scenarios with or without monetary values for some impacts. Researchers analyzed 164 complete responses from New Zealand council members and public officials.
What the study cannot show
- Only a small share of invitees responded; the scenario simplified a complex public decision, and cultural values were described in words.
- The study does not show that real policies change in the same way or that every cultural or environmental value should be expressed in money.
