Micro-incentive

What is a micro-incentive?

A micro-incentive is an informal term for a small reward offered to encourage a specified action. It can be monetary or nonmonetary. “Small” is relative to the person and context; the term does not identify one standard intervention or guaranteed mechanism.

Research example

In Thornton’s field experiment in rural Malawi, even a small cash incentive increased collection of HIV test results. The study tested a concrete action and reward, rather than an abstract micro-incentive category.

Design considerations

The reward amount, timing, eligibility rule, and effort required should be specified. A badge or message of praise should not be assumed to have the same effect as a cash payment.

For example, a workplace could offer a small token for completing a training task, or an app could award a badge for recording an activity. These describe possible reward arrangements, not demonstrated improvements in productivity or health. A design review should also ask who can meet the eligibility rule and whether access, time, or cost prevents some people from taking part.

Limits

Evidence for completing an incentivized action does not by itself show lasting habit formation, improved health, or effectiveness after rewards stop.
