Construcción de un modelo de scoring para el otorgamiento de crédito en una entidad financiera

RESUMEN: La Superintendencia Financiera de Colombia (SFC) mediante la Carta Circular 31 y la Circular Externa 11 de 2002, exige que todas las instituciones financieras deben implementar un Sistema de Administración del Riesgo Creditico (SARC); teniendo en cuenta la volatilidad de las variables financieras gracias a la globalización de los mercados financieros mundiales y la importancia de un sistema financiero fuerte. En este marco regulatorio, el presente trabajo implementa una metodología de análisis discriminante para la construcción de un modelo de Scoring de otorgamiento de crédito; mediante el análisis estadístico de variables cualitativas y cuantitativas dentro de una base de datos facilitadas por una cooperativa financiera del Valle de Aburrá con esto se pretende definir perfiles de prestatarios propensos al incumplimiento de sus obligaciones, y perfiles de prestatarios de buen comportamiento.ABSTRACT: The Superintendencia Financiera of Colombia (SFC) by the Carta Circular 31 and the Circular Externa 11 of 2002, it requires to all financial institutions implement a Risk Management System Credit, taking into account the volatility of financial variables through the world financial markets globalization and the importance of a strong financial system. In this regulatory framework, the paper proposes a grand model of credit scoring to define profiles of borrowers susceptible to default in their obligations, and profiles of borrowers with good behavior, that, through statistical analysis of qualitative and quantitative variables with a database provided by a financial cooperative in the Aburrá Valley

Metodología de las encuestas telefónicas

ABSTRACT: The telephone survey of recent introduction in Colombia show to a substantive advantage with respect to the actual surveys or by costs and saving of time and access an up-to-date information as the telephone interviews are developed. Nevertheless, parallel to these evident advantages arises the problem from the representativeness of the given information the distortion that can be given with the distribution of the obtained calls: in the homes to minors or people generally respond who do not represent the home (qualified interviewer); also there are serious problems with the perception of insecurity in the high layers what makes difficult the obtaining of reliable and valid information. This last problem has become a serious obstacle for this type of methodology."RESUMEN: Los sondeos telefónicos de reciente introducción en Colombia muestran una ventaja sustantiva respecto a las encuestas presenciales ya sea por costos y ahorro de tiempo y acceso a una información actualizada a medida que se desarrollan las entrevistas telefónicas. Sin embargo, paralelo a estas evidentes ventajas surge el problema de la representatividad de la información dado la distorsión que se puede dar con la distribución de las llamadas logradas: generalmente en los hogares responden menores o personas que no representan el hogar (no son respondientes calificados); también hay serios problemas con la percepción de inseguridad en los estratos altos lo que dificulta la obtención de información confiable y válida. Este último problema se ha convertido en un serio obstáculo para este tipo de metodología.

Characteristics, production insentives and the availability to pay for ecological milk in Medellín

RESUMEN: En este artículo se emplea valoración contingente para evaluar mejoras hipotéticas en la calidad ambiental de la leche, y se encuentra que es posible incentivar su producción, puesto que la disponibilidad a pagar de la demanda estimada en Medellín supera los precios de mercado y los costos de oportunidad de producir leche tradicional, en cuya producción se genera contaminación y degradación de tierras, y hay problemas de control y regulación por los organismos ambientales en Colombia. La lechería ecológica puede hacer parte de los mercados verdes y ser una opción de auto-regulación ambiental al encontrarse un mercado potencial por sus distintos atributos.ABSTRACT: In this article, contingent valuation is used to evaluate the hypothetical improvements of the environmental quality of milk. Results show that it is possible to encourage its production given that the willingness to pay of the estimated demand for Medellin exceeds market prices and the opportunity costs of producing traditional milk, which during its production generates soil pollution and degradation, and where the Colombian environmental regulation units have problems involving regulations and control. Organic dairy can be part of green markets and an option for environmental self-regulation when finding that potential market with as many attributes as this one

Exposición a plomo tetraetilo de los bomberos de las estaciones de gasolina en Medellin Colombia 1990

RESUMEN: Con el fin de medir los efectos que sobre la salud genera la exposición ocupacional al plomo orgánico (tetraetilo) usado como sustancia antidetonante y adicionado a la gasolina. Se estudió una poblacion de 60 trabajadores (isleros-bomberos) despachadores de gasolina en 25 estaciones de servicio de Medellín, a los cuales se les realizó: determinación de plomo en sangre y orina por espectofotometría de absorción atómica, zinc-protoporfirina por hematofluorómetro, hemoglobina y hematócrito, y examen médico; estos resultados se analizaron buscando su correlación con el tiempo de exposición, el que osciló entre cuatro meses y veinte años

Construction of a competitiveness index for the Colombian poultry sector

RESUMEN: Este trabajo plantea la construcción de un índice de competitividad para el sector avícola colombiano. Para construir el índice compuesto de competitividad se propusieron, mediante análisis de componentes principales (ACP), cuatro dimensiones que explican la competitividad. Estas dimensiones son: conocimiento (IC: 33,62%), dimensión productiva (IP: 26,94%), dimensión económica (IE: 26,84%) y dimensión tecnológica (IT: 12,57%). Se encontró que las regiones más competitivas en 2002 fueron, en orden descendente: Santander, Boyacá, Cundinamarca y Antioquia. Se puede concluir que la competitividad es un fenómeno multidimensional y que las variables asociadas c.ABSTRACT: This paper proposes the construction of a competitiveness index for the Colombian poultry sector. To construct the composite index of competitiveness, we used principal components analysis (ACP) to propose four dimensions that explain competitiveness. These dimensions are: knowledge (CI: 33.62%), productive dimension (IP: 26.94%), economic dimension (IE: 26.84%) and technological dimension (IT: 12.57%). It was found that the most competitive regions in 2002 were, in descending order: Santander, Boyacá, Cundinamarca and Antioquia. It can be concluded that competitiveness is a multidimensional phenomenon and that the variables associated with the origin of economic resources were closely related to the other variables
