Most product's life cycle is much shorter than I had imagined. In "The Life Cycle of Products: Evidence and Implications," Argente, Lee, and Moreira analyze 100 billion unique observations at the UPC by store by week level. Among other findings, they can trace product life cycles by type of product.
Brands can span individual UPCs (A) and last longer. Novel product introductions (B) last longer. Products sell well at introduction (C) fade faster. And more durable products (D) fade faster.
