Intention-based economic theories of reciprocity

Recientemente, varios experimentos han mostrado que los individuos exhiben un comportamiento auténticamente recíproco en interacciones anónimas que se dan una sola vez ('one-shot'). En tanto que se ha mostrado que la reciprocidad es relevante en múltiples campos de la economía, han existido varios intentos por modelar el comportamiento recíproco. Este documento revisa los modelos de reciprocidad que se fundamentan en las intenciones y presenta un ejemplo para el caso del manejo de los profesores en el sector público, en el que el gobierno ofrece un esquema de incentivos para la implementación de un programa. Este esquema tiene la estructura del dilema del prisionero. Tanto en los juegos simultáneos como secuenciales, los resultados de equilibrio puede ser distintos a los que predice la teoría convencional. ************************************************************************ In recent years, several experiments have shown that individuals exhibit authentic reciprocal behavior in anonymous one-shot interactions. As reciprocity has been shown to be relevant in several economic fields, there have also been several attempts to model reciprocical behavior. I review the intention-based models of reciprocity and present an example in teachers´ management in the public sector in which a government offers an incentive scheme to implement a program. The incentive scheme has the prisioner’s dilemma structure, In both simultaneous and sequential games, in equilibrium reciprocal teachers may reach other equilibria different from those predicted by the standard theory.Game theory, psychological games,Intention-based models, reciprocl behaviour

Algunas reflexiones sobre la evaluación en microeconomía

Continuando con un proceso de reflexión sobre la enseñanza de la microeconomía que inició hace cinco años, se introdujeron varios cambios en la evaluación de la microeconomía. Los cambios se han implementado en Microeconomía 3 y se espera que sus enseñanzas se implementen en otras materias del área y del programa

An approximation to the standard of living index: the colombian case

This document seeks to show the main properties of a standard of living index using the theoretical approach of Amartya Sen. We establish the link among concepts such as: welfare, well-being, agency achievement and standard of living. Optimal scaling methodology was fundamental in order to test the properties on the Colombian case. These properties are Monotonicity, No independence of irrelevant alternatives, Concavity, Informativity and Substituibility. Resumen. El documento busca mostrar las principales propiedades de un indicador de estándar de vida dentro del enfoque teórico de Amartya Sen. Establecemos un puente entre conceptos tales como: bienestar económico, bienestar, logro de agencia y estándar de vida. La metodología del Optimal scaling fue usada para probar las propiedades de Monotonicidad, No independencia de alternativas irrelevantes, Concavidad, informatividad y sustituibilidad. ********************************************************************** El documento busca mostrar las principales propiedades de un indicador de estándar de vida dentro del enfoque teórico de Amartya Sen.

El gasto en salud de los hogares colombianos: un análisis descriptivo

From the Choice Theory we considered the way in which certain population characteristics affect the households health expenditure in Colombia. The approach of this paper is based on Deaton’s work (1980), where the choice set of the individuals is the intercession of the budgetary set and the consumption set. The analysis of the paths of the health expenditure for the Colombian households has a variance analysis approach taking data from the “Encuesta de Calidad de Vida de 1997 (ECV97)”. We fund that the households spend the 9,62% of their current income in health. The most important variables that explain the paths of the health expenditure are the geographic location; the social-economic level of the households; the affiliation’ type to the health system; the occupation and the educative level of the household head; and the epidemiologists characteristic of the households. ********************************************************************* A partir de la teoría de la elección se plantea la forma como ciertas características poblacionales afectan el gasto en salud de los hogares colombianos. El enfoque está basado en el trabajo de Deaton (1980), donde el conjunto de elección de los individuos es la intercesión del conjunto presupuestal y el conjunto de consumo. El análisis de los senderos de gasto en salud para los hogares colombianos utiliza un enfoque de análisis de varianza tomando datos de la Encuesta de Calidad de Vida de 1997 -ECV97. En general se encuentra que los hogares gastan el 9.62% de sus ingresos corrientes en salud, y que las variables más importantes para explicar el sendero de gasto son la ubicación geográfica; el estrato del hogar; el tipo de afiliación al sistema de salud, el tipo de ocupación y el nivel educativo del jefe del hogar; y las características epidemiológicas del hogar.análisis de varianza, gasto en salud, teoría de la elección

Desarrollo, bienestar y comparaciones interpersonales

This document tries to schematize the basic concepts studied in the economic theory to evaluate life conditions of people. We show the different approaches of the old and new welfare economics and we conclude that the economic theory has arrived at a concept of welfare and justice extensively defined that allows to evaluate the agents in a distinct way and it also permits to consider alternative approaches when we are dealing with conditions of life. *********************************************************************** El presente documento intenta esquematizar los conceptos que han sido estudiados en la teoría económica y que son necesarios para evaluar las condiciones de vida de las personas. Se estudian las distintas posturas que se enmarcan tanto dentro de la vieja como de la nueva economía del bienestar y se concluye que la teoría económica ha llegado a un concepto de bienestar y justicia ampliamente definido que permite evaluar de una manera distinta a los agentes y que también, permite considerar posturas alternativas cuando se habla de condiciones de vida.

Kangaroo mother care had a protective effect on the volume of brain structures in young adults born preterm

Q1Q1Jóvenes adultosAim: The protective effects of Kangaroo mother care (KMC) on the neurodevelop-ment of preterm infants are well established, but we do not know whether the ben-efits persist beyond infancy. Our aim was to determine whether providing KMC in infancy affected brain volumes in young adulthood. Method: Standardised cognitive, memory and motor skills tests were used to determine the brain volumes of 20-year-old adults who had formed part of a randomised controlled trial of KMC versus incubator care. Multivariate analysis of brain volumes was conducted according to KMC exposure. Results: The study comprised 178 adults born preterm: 97 had received KMC and 81 were incubator care controls. Bivariate analysis showed larger volumes of total grey matter, basal nuclei and cerebellum in those who had received KMC, and the white matter was better organised. This means that the volumes of the main brain structures associated with intelligence, attention, memory and coordination were larger in the KMC group. Multivariate lineal regression analysis demonstrated the direct rela-tionship between brain volumes and duration of KMC, after controlling for potential confounders. Conclusion: Our findings suggest that the neuroprotective effects of KMC for pre-term infants persisted beyond childhood and improved their lifetime functionality and quality of life.https://orcid.org/0000-0001-6697-5837https://orcid.org/0000-0002-1923-3934https://orcid.org/0000-0001-5464-2701Revista Internacional - IndexadaA1N

Twenty-year follow-up of kangaroo mother care versus traditional care

Q1Q1e20162063BACKGROUND AND OBJECTIVES: Kangaroo mother care (KMC) is a multifaceted intervention for preterm and low birth weight infants and their parents. Short- and mid-term benefits of KMC on survival, neurodevelopment, breastfeeding, and the quality of mother–infant bonding were documented in a randomized controlled trial (RCT) conducted in Colombia from 1993 to 1996. The aim of the present study was to evaluate the persistence of these results in young adulthood. METHODS: From 2012 to 2014, a total of 494 (69%) of the 716 participants of the original RCT known to be alive were identified; 441 (62% of the participants in the original RCT) were re-enrolled, and results for the 264 participants weighing ≤1800 g at birth were analyzed. The KMC and control groups were compared for health status and neurologic, cognitive, and social functioning with the use of neuroimaging, neurophysiological, and behavioral tests. RESULTS: The effects of KMC at 1 year on IQ and home environment were still present 20 years later in the most fragile individuals, and KMC parents were more protective and nurturing, reflected by reduced school absenteeism and reduced hyperactivity, aggressiveness, externalization, and socio-deviant conduct of young adults. Neuroimaging showed larger volume of the left caudate nucleus in the KMC group. CONCLUSIONS: This study indicates that KMC had significant, long-lasting social and behavioral protective effects 20 years after the intervention. Coverage with this efficient and scientifically based health care intervention should be extended to the 18 million infants born each year who are candidates for the method
