Abstract

fetched live from OpenAlex

In a competitive market renewable energy subsidies or postponement of carbon pricing tend to boost emissions and global warming in the short run. This so-called Green Paradox effect may be reversed if fossil-fuel firms operate under an oligopoly and the number of members is low enough. A reversal of the Green Paradox always occurs under a fossil fuel monopoly. If the extraction costs of fossil fuel depend on the aggregate remaining stock of reserves, Green Paradox effects vanish if the number of oligopolists becomes infinitely large. For an intermediate number of members, a Green Paradox occurs. The strength of the Green Paradox effect depends non-monotonically on the number of oligopolists. We also show that a Green Paradox is more likely for higher slopes of the demand curve, higher sensitivities of unit extraction costs with respect to remaining reserves, and lower interest rates.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
