How would you test whether the definition of a measure changes a market?

Machine Commerce Conditions MCC-001 · Published

From MCC-001, an essay: a hypothesis, not a measurement.

The short answer

Among buyers who actually use a performance measure, change the definition and see who gets chosen. The essay proposes checking whether changes to what counts as success, what is included or excluded, how fresh evidence must be or how much history is required alter which sellers receive consideration or demand.

As published in the issue

Third, does the definition of the measure change the market? Among buyers who actually use a performance measure, do changes in the definition of success, inclusion and exclusion rules, evidence freshness or required history alter which sellers receive consideration or demand? A metric’s publication alone would establish little. Changes in purchasing behavior would show when measurement begins to operate as economically consequential infrastructure.

Why it matters

Publishing a metric proves nothing about its influence. The essay's point is that a measure becomes infrastructure when changing it changes purchasing behaviour.

What we measured

Nothing here was counted. The essay states this test and states that it has not run; what our measured series publishes about what a label actually tests is linked below.
