Varian and Carl Shapiro's 1999 Information Rules: A Strategic Guide to the Network Economy — the book that codified the cost structures, network effects, and switching dynamics now operating at unprecedented scale in the AI market.
Information Rules was the strategic guide that taught a generation of technologists and policymakers how information markets actually work. Published in 1999 at the peak of the dot-com euphoria, its central insight was structural rather than predictive: information goods are expensive to produce and cheap to reproduce, and this cost asymmetry produces a specific and predictable set of consequences — pricing tending toward zero absent differentiation, markets tending toward concentration, value migrating to whatever remains scarce. The book's enduring power is that its framework survived the technologies it was written to analyze. Fax machines, DVDs, and Napster are dated references.
