Output Quality, Productivity, and Demand: Evidence from the Chinese Steel Industry

open access: yesThe RAND Journal of Economics, Volume 57, Issue 3, Page 784-807, Autumn (Fall) 2026.
ABSTRACT Unobserved objective output quality complicates the analysis of firm productivity and demand because higher‐quality products entail higher costs but offer greater consumption benefits. Using a panel of firms with output quality data, we decompose quantity‐based productivity into fundamental productivity and the costs of quality, and separate ...
