Títulos de deuda pública externa y su impacto en el tipo de cambio paralelo no oficial: caso venezolano, periodo (2006-2009)
Bibliographic record
Abstract
"La economía venezolana se ve afectada significativamente por las distorsiones que se producen entre el tipo de cambio oficial y el tipo de cambio del mercado paralelo. En este trabajo de investigación, se emplea la técnica Event Study para evaluar las variaciones anormales en el tipo de cambio del mercado paralelo no oficial en torno a la fecha en que se produce el anuncio de los resultados de adjudicación de siete títulos de deuda externa, como mecanismo permuta, emitidos durante el periodo (2006-2009). Los resultados demuestran, de acuerdo al test de Corrado (1989), que existe suficiente evidencia para considerar la presencia de diferencias significativas, con un nivel de confianza del 95%. Se concluye que en el tipo de cambio del mercado paralelo no oficial se aprecia la moneda local respecto al dólar, sólo cuando a los inversionistas les resultan atractivos estos instrumentos como mecanismo permuta."

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.
