Modelo de inversión basado en la ecuación de Euler con límite máximo de endeudamiento: Evidencia empírica internacional
Bibliographic record
Abstract
Este trabajo estudia los determinantes de la inversión empresarial, incorporando un límite máximo de endeudamiento a un modelo de inversión basado en la ecuación de Euler. Las diferentes versiones del modelo desarrollado se han estimado por el Método Generalizado de los Momentos para datos de Canadá, España, Estados Unidos y Reino Unido. Los resultados obtenidos muestran que la sensibilidad de la inversión al cash flow es mayor para las empresas restringidas financieramente que para las no restringidas. Esta mayor sensibilidad es causada por la mayor repercusión que tienen las imperfecciones del mercado en las empresas restringidas financieramente. En consecuencia, se pone de manifiesto la necesidad de considerar por separado las empresas restringidas y no restringidas para identificar los determinantes de la inversión empresarial. This paper studies the determinants of firms’ investment. Our model with a credit limit is derived from the Euler equation. The set of models obtained derived have been estimated by using the Generalized Method of Moments with data from Canada, Spain, The United States and The United Kingdom. Our results show that the sensitivity of investment to cash flow is greater for financially constrained firms than for those financially unconstrained. This greater sensitivity is caused by the higher effect of the capital market imperfections in the financially constrained firms. As a consequence, a separate study of the firm according to the financial constraints suffered is required in order to precisely identify the determinants of firms‘investment

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.
