Abstract
Do capital markets reflect the possibility that fossil fuel reserves may become "stranded assets" in the transition to a low carbon economy? We examine the relation between oil firms' value and their proved reserves. Using a sample of 600 North American oil firms for the period 1999 to 2018, we document that while reserves are an important component of oil firm value, the growth of these reserves has a negative effect on firm value. This negative effect on value is stronger for oil producers with higher extraction costs. When we decompose total reserves into developed and undeveloped reserves, we show that the negative effect of reserves growth on value is due to firms growing their undeveloped oil reserves. Unlike developed, undeveloped reserves require major capital expenditures and longer time before they can be extracted. We also document that the negative effect is stronger for undeveloped oil reserves located in countries with strict climate policies. Our evidence is consistent with markets penalizing future investment in undeveloped reserves growth due to climate policy risk. High level of institutional ownership, stock market liquidity and analyst coverage do not change the negative effect of undeveloped reserves growth on firm value.

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
