Health insurance as a strategy for access : Streamlined facts of the Colombian Health Care Reform

La reforma colombiana al sistema de salud (Ley 100 de 1993) estableció, como estrategia para facilitar el acceso, la universalidad de un seguro de salud que se adquiere mediante la cotización en el régimen contributivo o mediante la afiliación gratuita al régimen subsidiado, con la meta de cubrir a toda la población con un plan de beneficios único que comprende servicios de todos los niveles de atención. En el documento se analizan los principales hechos estilizados de la reforma en cuanto a cobertura del seguro y acceso y, mediante modelos logit, se estiman los determinantes de la afiliación y del acceso, con datos de las encuestas de calidad de vida de 1997 y 2003. Se destaca que la cobertura pasó del 20% de la población en 1993 al 60% en 2004, aunque parece imposible alcanzar la universalidad; la estructura y evolución de la cobertura muestran que los dos regímenes son complementarios, de modo que mientras el contributivo tiene mayor presencia en las ciudades y entre la población con empleo formal, el subsidiado tiene mayor peso entre la población rural y con bajos niveles de ingresos; por otra parte, el seguro tiene ventajas para la población subsidiada, con una mayor probabilidad de utilización de servicios, aunque el plan es inferior al del contributivo y existen barreras para el acceso.

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.

The determinants of the health status in a developing country: results from the Colombian case

El artículo busca encontrar evidencia empírica de los determinantes de la salud, como una medición de capital salud en un país en desarrollo después de una profunda reforma en el sector salud. Siguiendo el modelo de Grossman (1972) y tomando factores institucionales, además de las variables individuales y socioeconómicas. Se usaron las encuestas de 1997 y 2000 donde se responde subjetivamente sobre el estado de salud y tipo de afiliación al sistema de salud. El proceso de estimación usado es un probit ordenado. Los resultados muestran una importante conexión entre las variables individuales, institucionales y socioeconómicas con el estado de salud. El efecto de tipo de acceso al sistema de salud presiona las inequidades en salud.

La organización interna de los partidos políticos como determinante del grado de polarización del sistema partidario en Colombia (2002-2014)

El presente trabajo de grado tiene como propósito examinar la incidencia de la organización interna de los partidos políticos colombianos sobre el grado de polarización del sistema partidario, durante el periodo 2002-2014. De esta manera, sostiene que la poca disciplina interna determinó el bajo grado de polarización del sistema, facilitando la conformación de coaliciones contradictorias, efímeras e indisciplinadas en el Congreso y en el Ejecutivo a nivel nacional y local. Por ello, se exponen los principales cambios que sufrió el sistema partidario a partir de las reformas implementadas, y se analiza el comportamiento de las coaliciones de gobierno en el Congreso. Finalmente, se examina el comportamiento de la coalición de la Unidad Nacional en las elecciones locales de 2011, utilizando como marco para este trabajo algunos conceptos básicos sobre la teoría de partidos.

Leadership and performance in multicultural business environments a qualitative study in German-Colombian teams

Multicultural leadership is a topic a great interest in nowadays globalized work environment. Colombia emerges as an attractive marketplace with appealing business opportunities, especially for German enterprises. After presenting Colombia’s current political, social and economic situation, the thesis elaborates the complex subject of cultural differences while focusing on the peculiarities of German and Colombian national cultures. The resulting implications for a team’s collaboration and leader effectiveness are theoretically supported with reference to the landmark studies of Hofstede and GLOBE. By utilizing semi-structured interview techniques, a qualitative research enriches the previous findings and gives an all-encompassing insight in German-Colombian teamwork. The investigation identifies distinctive behavioral patterns and relations, which imply challenges and factors of success for multicultural team leaders. Finally, a categorical analysis examines the influence of cultural traits on team performance and evaluates the effectiveness of the applied leadership style.

An Empirical Examination of the Determinants of Foreign Direct Investment: A Firm-Level Analysis for the Colombian Economy

We use a large firm level data set to investigate the determinants of foreign direct investment(FDI) in Colombia. We estimate econometric models for the determinants of the probabilitythat a firm receives FDI, as well as for the factors that help to explain the foreign share in afirm’s capital. The results show that firms listed on the stock market, involved in foreign tradeactivities, and operating in sectors with greater capital intensity are more likely to be recipientsof FDI. Also, the probability of a firm receiving FDI is directly related to its size.

Congress composition and electoral advantage

In 2003, an electoral reform changed the mechanism to assign seats in the Colombian Congress. I simulate the 2006 Senate elections using the previous assignment mechanism to determine which senators benefited from the reform, i.e. would have not been elected had the reform not been made. With the results of the simulation, I use a regression discontinuity design to compare the senators that would have been barely elected anyways with those who would have lost, but were near to be elected. I check the differences in the amount of law drafts presented, the attendance to voting sessions, and a discipline index for each senator as proxy of their legislative behavior. I find that the senators benefiting from the reform present a different legislative behavior during the 4-year term with respect to the senators that would have been elected anyways. Since the differential legislative behavior cannot be interpreted as being better (worse) politician, I examine if the behavioral difference gives them an electoral advantage. I find no difference in the electoral result of 2010 Senate election in terms of the probability of being (re)elected in 2010, the share of votes, the share of votes within their party list, and the concentration of their votes. Additionally, I check the probability of being investigated for links with paramilitary groups and I find no differences. The results suggest that political reforms can change the composition of governing or legislative bodies in terms of performance, but it does not necessarily translate into an electoral advantage.

Free and Fair? A Challenge for the EU as Georgia and Ukraine gear up for elections. CEPS Commentary, 27 September 2012

In an important test for democracy, Georgia and Ukraine will go to the polls for parliamentary elections on the 1st and 28th of October, respectively. The political leaders of these two Eastern Partnership countries have committed themselves to European values and principles – rhetorically. In reality, the promise of their colour revolutions is unrealised and they have shifted further towards authoritarianism, albeit following different paths in their respective post-revolution periods.

Influence of aluminum hydroxide on potassium release from two Colombian soils

The effect of sesquioxides on the mechanisms of chemical reactions that govern the transformation between exchangeable potassium (Kex) and non-exchangeable K (Knex) was studied on acid tropical soils from Colombia: Caribia with predominantly 2 : 1 clay minerals and High Terrace with predominantly 1 : 1 clay minerals and sesquioxides. Illite and vermiculite are the main clay minerals in Caribia followed by kaolinite, gibbsite, and plagioclase, and kaolinite is the major clay mineral in High Terrace followed by hydroxyl-Al interlayered vermiculite, quartz, and pyrophyllite. The soils have 1.8 and 0.5% of K2O, respectively. They were used either untreated or prepared by adding AlCl3 and NaOH, which produced aluminum hydroxide. The soils were percolated continuously with 10mM NH4OAc at pH 7.0 and 10 mM CaCl2 at pH 5.8 for 120 h at 6 mL h(-1) to examine the release of Kex and Knex. In the untreated soils, NH4+ and Ca-2(+) released the same amounts of Kex from Caribia, whereas NH4+ released about twice as much Kex as Ca2+ from High Terrace. This study proposes that the small ionic size of NH4+ (0.54nm) enables it to enter more easily into the K sites at the broken edges of the kaolinite where Ca2+ (0.96 nm) cannot have access. As expected for a soil dominated by 2 : 1 clay minerals, Ca2+ caused Knex to be released from Caribia with no release by NH4+. No Knex was released by either ion from High Terrace. After treatment with aluminum hydroxide, K release from the exchangeable fraction was reduced in Caribia due to the blocking of the exchange sites but release of Knex was not affected. The treatment increased the amount of Kex released from the High Terrace soil and the release of Knex remained negligible although with Ca2+ the distinction between Kex and Knex was unclear. The increase in Kex was attributed to the initially acidic conditions produced by adding AlCl3 which may have dissolved interlayered aluminum hydroxide from the vermiculite present, thus exposing trapped K as exchangeable K. The subsequent precipitation of aluminum hydroxide when NaOH was added did not interfere with the release of this K, and so was probably formed mostly on the surface of the dominant kaolinite. Measurement of availability of K by standard methods using NH4 salts could result in overestimates in High Terrace and this may be a more general shortcoming of the methods in kaolinitic soils.
