Autonomy in Subnational Income Taxes
Bibliographic record
Abstract
Subnational tax autonomy is a cornerstone of a viable system of fiscal federalism. The underlying principle is that spending by constituent units in a federal or quasi federal country is paid for by revenues that are under the control of that unit. Economists recommend that the taxation base remain the same across all constituent units in a country to minimize administrative and compliance costs as well as tax avoidance activities. There are important differences between constituent units of federal or quasi-federal states in OECD countries with respect to both powers for taxation of personal income and the use made of such powers, if any. Autonomy in Subnational Income Taxes examines tax autonomy as a powerful tool in setting tax rates. Two key issues are examined in detail: first, why proposals giving more power to set tax rates have been implemented (Spain), put forward (UK), stalled (Belguim), or set aside (Germany), and second, how such powers are used in federations whose constituent units have them (Canada, Switzerland, and the United States).

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.
