Abstract
This paper first assesses the current Colombian mining tax-and-royalty regime in comparison with other countries from the points of view of efficiency, competitiveness and revenue performance. It then discusses the theoretical convenience of introducing alternative designs for a resource rent tax (RRT) to be applied to new mining projects, together with a reduced common royalty rate for all minerals, and simulates their potential efficiency, competitiveness and revenue-performance effects. In particular, it examines alternative interactions between the RRT, the royalty regime and the corporate income tax (royalties creditable against the RRT or deductible from its tax base; accepting or not corporate income tax deductibility from the RRT tax base), under alternative RRT tax rates. It also discusses alternative capital return allowances and the pros and cons of project-by-project versus sectorial ring fencing, and sharing RRT revenues between the national and sub-national governments. It concludes with a detailed blueprint for reform based on these discussions, assessments and simulations, as well as political economy and administrative considerations for the specific case of Colombia.Este trabajo evalúa la eficiencia, competitividad y capacidad de recaudo del régimen tributario y de regalías colombiano en comparación con el de otros países mineros relevantes. Posteriormente, propone la implementación de un “Resource Rent Tax” (RRT) para proyectos mineros futuros (junto con una reducción y unificación de la tasa de regalías entre minerales) y modela el impacto que tendría éste sobre la eficiencia y el recaudo. Se examinan la interacción entre el RRT, las regalías y el impuesto de renta bajo distintos diseños y tasas de RRT y costo de oportunidad del capital. También se analiza si es preferible tener “ringfencing” a nivel de proyecto o a nivel sectorial. El trabajo concluye con una propuesta de reforma junto con consideraciones administrativas y políticas para una exitosa implementación.

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 it
