The Hoberg and Maksimovic text-based measures of product life cycles are
based on firm disclosures in their 10-Ks filed with the Securities and
Exchange Commission.
The measures are based on the Abernathy and Utterback (1979) life cycle and
span four stages. (1) Product
development stage, (2) Process optimization stage, (3) Mature product stage,
and (4) Product decline stage.
We thank Christopher Ball at metaHeuristica
for access to outstanding text analytic tools that made this project
possible.
