Abstract
Abstract This article proposes a 2‐period model featuring jointly habit formation, consumption externalities and asymmetric information to investigate their impacts on optimal labour and saving taxes. Regarding the effect of habit formation only, our model suggests that both labour taxation in the first period and a capital subsidy between the first and second period are used to deter consumption in the first period. However, when the impact of consumption externalities alone is considered, consumption externalities advocate for higher labour taxation for all agents. Finally, our quantitative results show that with the rising degree of consumption externalities, the discrepancy between marginal capital tax rates under full information and their values under asymmetric information falls, so does the change in the gap between the marginal labour income tax rates of the skilled and the unskilled. Conversely, as the degree of habit formation increases, the change in marginal capital tax rates under full information and under asymmetric information expands, so does the change in the gap between the marginal labour income tax rates of the skilled and the unskilled.

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
