Green Innovation and Economic Growth in a North–South Model
Bibliographic record
Abstract
Abstract If one region of the world switches its research effort from dirty to clean technologies, will other regions follow? To investigate this question, this paper builds a North–South model that combines insights from directed technological change and quality-ladder endogenous growth models with business-stealing innovations. While North represents the region with climate ambitions, both regions have researchers choosing between clean and dirty applications, and the resulting technologies are traded. Three main results emerge: (1) In the long run, if the North’s research and development (R&D) sector is sufficiently large, researchers in South will follow the switch from dirty to clean R&D made by researchers in North, motivated by the growing value of clean markets. (2) If the two regions direct research effort toward different sectors and the outputs of the two sectors are gross substitutes, then the long-run growth rates in both regions will be lower than if the global research effort were invested in one sector. (3) If the North’s government induces its researchers to switch to clean R&D through clean technology subsidies, the welfare-maximising choice for South is to ensure that all of its researchers switch too, unless the social discount rate is high. The last result is true even if the South’s R&D sector is large.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
