Club convergence of sustainable development: fresh evidence from developing and developed countries
Bibliographic record
Abstract
Abstract Sustainability is a process that characterizes in a broad sense a nation’s ecological performance and may display a time-varying pattern. Such dynamic trajectories may vary among different countries and prompt not only intriguing questions on space–time convergence but also on the possibility of club convergence. The scope of this study is to investigate the long-run convergence pattern of 137 countries, as presented by their sustainable development index (SDI) over the period 1990–2019. The statistical–econometric analysis used to identify convergence across (groups of) countries is based on the advanced Phillips and Sul (JAE 24:1153–1185, 2009; ECTA 75:1771–1855, 2007) method. The empirical findings from our study allow us to identify two SDI convergence clubs of countries. The first and the biggest club includes mainly the developing African and Asian countries; whereas, the second club includes many OECD countries including inter alia the US, Canada, and Australia. Our analysis brings to light that the transition paths of these two clubs show a significant divergence pattern; this a-symmetry calls also into question the effectiveness of global green policies, such as the clean development mechanism as foreseen in the Kyoto protocol.

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.
