Abstract

fetched live from OpenAlex

The “long tail” theory was celebrated by BusinessWeek as the biggest idea of the year 2004, soon after the book The Long Tail by Chris Anderson was published. The long tail theory calls for applying a low-budget strategy—producing a (relatively) large number of products with (relatively) low investment levels. However, some other cultural industries may tell a different story. The concentration of the most popular titles in the video game industry is growing, a phenomenon known as the blockbuster phenomenon. This phenomenon suggests that firms may adopt a high-budget strategy—producing a (relatively) small number of products with (relatively) high investment levels. In “Market Entry and Competition Under Network Effects,” Y. Feng and M. Hu analytically study the impact of a network effect on entry decisions and investment strategies (i.e., the high-budget versus low-budget strategies) adopted by competing firms based on which they further provide a theory that links the ex post sales volume concentration with the ex ante product variety in a market under network effects.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
