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.
