Punctuated Equilibrium in Technological Capabilities: Commercial Selection and the Predictability of Frontier Advances
Abstract
Evolutionary accounts of technological change connect new technical opportunities with economic selection. Using approximately 1.74 million electronic-component product records, we examine the tempo of capability-frontier improvement alongside the diversity of commercially offered products. In a detailed analysis of 29 manually selected capabilities, 77.8% of substantial-advance episodes consist of a single observed advance year. Across eligible three-year windows beginning with an advance, the initial observed gain accounts for an average of 79.3% of total log-capability improvement. The median share of product records near the frontier is 1.46%. Motivated by the interaction of technology push and demand pull, we extend the analysis to 204 capabilities and conduct forward out-of-sample comparisons between models using frontier history and models additionally incorporating product composition, manufacturer competition, and population dynamics. The additional indicators do not improve forecasts of subsequent frontier advances. The results document concentrated frontier gains alongside a broad distribution of commercially offered specifications. Stylized comparisons of incremental service value and switching costs identify candidate mechanisms linking application-specific valuation and production scale to the economic relevance of technical opportunities. They also specify the price, quantity, and application-level observations needed to evaluate these interpretations. We propose source-grounded, language-model-assisted extraction of demand-related information from dated external documents, with validation against independently observed market data.
