Equity Valuation and Current Cost Disclosures: the Case of Mexico
Bibliographic record
Abstract
This study uses an accounting‐based valuation model to investigate the relation between the market value of publicly traded Mexican firms and their disclosures of price‐level adjusted accounting information. The model is estimated on a sample of Mexican companies during 1987–1990, when annual inflation rates in Mexico decreased from 130 per cent to 20 per cent. The results indicate that general price level‐adjusted and current cost disclosures explain a significant portion of the cross‐sectional variation in the market‐to‐book ratios of the sample firms. Further, the explanatory power of holding gains is robust to decreases in the general level of inflation, which suggests that current cost and constant peso disclosures are relevant for determining firm value over a wide range of inflation rates. These results are particularly important now since the Mexican Institute of CPAs has proposed eliminating the measurement of holding gains in order to make Mexican financial statements more comparable to US and Canadian GAAP.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
