Diminishing marginal returns justify logging GDP, encoding normative assumptions.

Evidence

The claim is that a 1, 000 USD increase for a wealthy person or country means a lot less to them than a 1, 000 USD increase for a poor person. This produces the flattening curve in the upper regions of GDP per capita. This is another example where normative concerns often play a role. — Gary Goertz, Social Science Concepts and Measurement, 735
