Ahorro para el retiro en Colombia: patrones y determinantes

La decisión de los individuos acerca del ahorro para el retiro ha sido abordada teóricamente bajo la hipótesis de que el sistema de seguridad social se comporta como un sustituto de otros mecanismos de ahorro. Este documento presenta evidencia de los patrones y determinantes del ahorro para el retiro en Colombia a partir de la Gran Encuesta Integrada de Hogares de 2007. Los resultados muestran que el 63% de los ocupados declaran no ahorrar para su vejez. A partir de modelos de selección discreta se encuentra que individuos jóvenes, de sexo masculino, con menor nivel educativo, residentes en zonas rurales, y trabajadores cuenta propia, presentan menores probabilidades de ah orrar para el retiro; además las características socioeconómicas resultan significativas en la determinación del mecanismo de ahorro utilizado.

Media bias and central bank response. Evidence from the nominal exchange rate behavior in Colombia

Since 1991 Colombia has had a market-determined Peso - US Dollar Nominal Exchange Rate (NER), after more than 20 years of controlled and multiple exchange rates. The behavior (revaluation / devaluation) of the NER is constantly reported in news, editorials and op-eds of major newspapers of the nation with particular attention to revaluation. The uneven reporting of revaluation episodes can be explained by the existence of an interest group particulary affected by revaluation, looking to increase awareness and sympathy for help from public institutions. Using the number of news and op-eds from a major Colombian newspaper, it is shown that there is an over-reporting of revaluation episodes in contrast to devaluation ones. Secondly, using text analysis upon the content of the news, it is also shown that the words devaluation and revaluation are far apart in the distribution of words within the news; and revaluation is highly correlated with words related to: public institutions, exporters and the need of assistance. Finally it is also shown that the probability of the central bank buying US dollars to lessen revaluation effects increases with the number of news; even though the central bank allegedly intervenes in the exchange rate market only to tame volatility or accumulate international reserves.

Natural disasters and clientelism: the case of floods and landslides in Colombia

What are the effects of natural disasters on electoral results? Some authors claim that catastrophes have a negative effect on the survival of leaders in a democracy because voters have a propensity to punish politicians for not preventing or poorly handling a crisis. In contrast, this paper finds that these events might be beneficial for leaders. Disasters are linked to leader survival through clientelism: they generate an in-flow of resources in the form of aid, which increase money for buying votes. Analyzing the rainy season of 2010-2011 in Colombia, considered its worst disaster in history, I use a difference-in-differences strategy to show that in the local election incumbent parties benefited from the disaster. The result is robust to different specifications and alternative explanations. Moreover, places receiving more aid and those with judicial evidence of vote-buying irregularities, are more likely to reelect the incumbent, supporting the mechanism proposed by this paper.

Parametric pension reform and the intensive margin of labor supply, evidence from Colombia

We analyze the effect of a parametric reform of the fully-funded pension regime in Colombia on the intensive margin of the labor supply. We take advantage of a threshold defined by law in order to identify the causal effect using a regression discontinuity design. We find that a pension system that increases retirement age and the minimum weeks during which workers must contribute to claim pension benefits causes an increase of around 2 hours on the number of weekly worked hours; this corresponds to 4% of the average number of weekly worked hours or around 14% of a standard deviation of weekly worked hours. The effect is robust to different specifications, polynomial orders and sample sizes.

Poverty impacts of agricultural policy adjustments in an opening economy: the case of Colombia

We aim to contribute to the assessment of poverty impacts on the rural sector arising from agricultural policy adjustments in Colombia. For this we use an agriculture specialized static CGE model, jointly (sequentially) with a microsimulation model that allows for effective job relocation. Results indicate that the sectoral impact of the program implemented tends to be small and has considerable variability across crops. They also show that the highest impacts come from the irrigation and land improvements component of the program. Lastly, although it reduces poverty, poverty impacts are small and tend to concentrate in rural households toward the middle of the income distribution ladder.

Productivity growth in electric energy retail in Colombia. A bootstrapped malmquist indices approach

This paper offers a productivity growth estimate for electric energy commercialization firms in Colombia, using a non-parametric Malmquist bootstrap methodology. The estimation and methodology serve two main purposes. First, in Colombia Commercialization firms are subject to a price-cap regulation scheme, a non-common arrangement in the international experience for this part of the industry. Therefore the paper’s result suggest an estimate of the productivity factor to be used by the regulator, not only in Colombia but in other countries where commercialization is a growing part of the industry (renewable energy, for instance). Second, because of poor data collection from regulators and firms themselves, regulation based on a single estimation of productivity seems inappropriate and error-prone. The nonparametric Malmquist bootstrap estimation allows an assessment of the result in contrast to a single one estimation. This would open an opportunity for the regulator to adopt a narrower and more accurate productivity estimation or override an implausible result and impose a productivity factor in the price-cap to foster the development of the industry.

Profundización, apertura y cierre de mercados de exportación a nivel sectorial en Colombia : una estimación de los márgenes del comercio y su relación con el ciclo económico

En este trabajo se explora, desde el punto de vista empírico, el comportamiento de la profundización, apertura y cierre de mercados de exportación a nivel sectorial para Colombia durante el periodo 1997- 2010, con énfasis en los dos periodos de recesión que presenta la economía durante el mismo. Para ello se emplea una metodología de descomposición de los cambios registrados por el comercio, en sus márgenes intensivo y extensivo, que permite la identificación de estos fenómenos y su observación tanto a lo largo del tiempo como a nivel transversal. Los resultados indican que, en el corto plazo, el margen intensivo del comercio explica la mayor parte de las variaciones en las exportaciones, en tanto que en el mediano plazo se encuentra una importante contribución del margen extensivo a éstas. Adicionalmente, desde el punto de vista sectorial, la crisis de 1997-1999 no presenta un patrón homogéneo en términos del comportamiento de los márgenes del comercio, en tanto que la de 2008- 2009 se caracteriza por presentar un patrón más homogéneo a través de los distintos sectores de la actividad económica.

An analysis of the relationship between wages in the public and private sector in colombia : a panel data approach

This document examines the time-series properties of the wage differentials that arise between the public and private sector in Colombia during the sample period 1984 to 2005. We Find conflicting results in unit-root and stationary tests when looking at wage differentials at an aggregate level (such as for men, women or both). However, when we analyse wage differentials at higher levels of disaggregation, treat them jointly as a panel of data, and allow for the presence of potential cross section dependence, there is more supportive evidence for the view that wage differentials are stationary. This implies that although wage differentials do exist, they have not been consistently increasing (or decreasing) over time.

Publicness of goods and violent conflict : evidence from Colombia

How the degree of publicness of goods affect violent conflict? Based on the theoretical model in Esteban and Ray (2001) we find that the effect of the degree of publicness depends on the group size. When the group is small (large), the degree of publicness increases (decreases) the likelihood of conflict. This opens an empirical question that we tackle using microdata from the Colombian conflict at the municipality level. We use three goods with different publicness degree to identify the sign of the effect of publicness on conflict. These goods are coca crops (private good), road density (public good subject to congestion) and average education quality (a purer public good). After dealing with endogeneity issues using an IV approach, we find that the degree of publicness reduces the likelihood of both paramilitary and guerrilla attacks. Moreover, coca production exacerbates conflict and the provision of both public goods mitigates conflict. These results are robust to size, geographical, and welfare controls. Policies that improve public goods provision will help to fight the onset of conflict.

An approximation to the digital divide among low income people in Colombia, Mexico and Perú: two composite indexes

El estudio analiza los determinantes de uso y acceso a las tecnologías de información y comunicación en personas de bajos ingresos en pasases como Colombia, México y Perú. El punto central está en analizar las diferencias entre países de acuerdo a diferentes variables socioeconómicas. Se encuentra que la variable que más explica el nivel de acceso digital es la escolaridad. De otro lado no se encuentra una brecha por género sino en Perú. Los resultados también indican que cuando solo se tienen en cuenta las tecnologías más ‘avanzadas’, las diferencias entre la población son más notorias

Seguridad democrática, presencia de la policía y conflicto en Colombia

Este artículo evalúa uno de los componentes fundamentales de la política más icónica del gobierno de Álvaro Uribe: la ´ Seguridad Democrática. En particular, se evalúa el impacto sobre la intensidad del conflicto armado de los despliegues y refuerzos de policía en municipios con poca o nula presencia policial antes de agosto de 2002. Para ello se utiliza el estimador de diferencia en diferencias que compara el cambio en la dinámica del conflicto una vez se asignan los nuevos efectivos a los municipios receptores, relativo al cambio ocurrido simultáneamente en los municipios no receptores. Nuestros resultados sugieren que tanto los despliegues (instauración de inspecciones de policía en municipios que carecían de ´estas) como los refuerzos (envío de nuevos efectivos a municipios con poca presencia policial previa) generan incrementos en el número de ataques guerrilleros. Por otro lado, también hay evidencia que en los casos en los que la asignación de efectivos policiales estuvo acompañada de la movilización de tropas del ejército el conflicto disminuyó en las áreas afectadas, lo que sugiere que la coordinación de las fuerzas armadas resulta clave para el éxito de iniciativas regionales de seguridad.

Seguros de desempleo: revisión de literatura y propuesta para Colombia

En este artículo se estudia la posibilidad de introducir seguros de desempleo en Colombia. En una primera parte, se propone una revisión de literatura de los seguros de desempleo en la cual se exponen las ventajas generadas por una cobertura contra este riesgo, así como sus inconvenientes. En una segunda parte, se estudian varios escenarios para introducir seguros de desempleo en Colombia. Después de haber presentado el contexto del mercado laboral y de las normas que lo vigilan, se proponen varios diseños que abordan la gestión y la administración del riesgo de desempleo en Colombia. Igualmente se presentan algunas consideraciones teóricas para la valoración del costo del aseguramiento, las cuales incorporan los efectos del riesgo moral sobre la duración y la incidencia del desempleo.

Short Term Health Shocks and School Attendance: The Case of a Dengue Fever Outbreak in Colombia.

This paper makes use of a short, sharp, unexpected health shock in the form of the 2010 Colombian Dengue outbreak to examine the direct and indirect impact of negative health shocks on behaviour of households in affected areas. Our analysis combines data from several sources in order to obtain a comprehensive picture of the influence of the outbreak, and furthermore to understand the underlying mechanisms driving the effects. Our initial analysis indicates that the outbreak had a substantial negative effect on the health status of adults and adversely affected their ability to function as usual in their daily lives. In our aggregated school data, in areas with high levels of haemorrhagic Dengue we observe a reduction innational exam attendance (last year of secondary school) and on enrolment rates in primary education. Further analysis aims to exploit detailed individual level data to gain a more in depth understanding of the precise channels through which this disease influenced the behaviour and outcomes of the poor in Colombia.

Statistical inference for testing Gini coefficients: an application for Colombia

This paper uses Colombian household survey data collected over the period 1984-2005 to estimate Gini coe¢ cients along with their corresponding standard errors. We Önd a statistically signiÖcant increase in wage income inequality following the adoption of the liberalisation measures of the early 1990s, and mixed evidence during the recovery years that followed the economic recession of the late 1990s. We also Önd that in several cases the observed di§erences in the Gini coe¢ cients across cities have not been statistically signiÖcant.

Tendencias históricas y regionales de la adjudicación de baldíos en Colombia

El presente documento hace una revisión de la política de reforma agraria en Colombia desde principios del siglo XX hasta 2012, caracterizada por la adjudicación de baldíos a campesinos. En este documento, se busca dar cuenta de la magnitud e importancia de esta política pública que ha perdurado a lo largo del tiempo y con una dinámica continua desde sus inicios, con el fin de aportar a la amplia literatura sobre reforma agraria en Colombia que, si bien analiza las tensiones propias de esta política no cuenta con datos desagregados del comportamiento de la política para más de un siglo. Igualmente se hace un recorrido regional que evidencia la dinámica de la reforma agraria en diferentes regiones a lo largo del tiempo.
