Este artículo presenta una primera propuesta de determinación de subsidios y contribuciones de tarifas de servicios públicos domiciliarios – SPD para la Capital colombiana, que no parta de una clasificación de grupos (estratos socioeconómicos). A partir de un ejercicio exploratorio, se diseña un esquema de pagos del servicio de acueducto a partir del avalúo catastral del inmueble en que habita cada hogar. El ejercicio establece el pago por unidad de consumo de agua, de manera que cada hogar en Bogotá destine una misma proporción de su gasto total al gasto en el servicio de acueducto y garantiza que el total de pagos cubran los costos de provisión del servicio.

Transfers to women may affect their bargaining power within the household and consequently their well-being. We analyze the effects of the 2004/2005 pension reform in Argentina, that resulted in an unexpected and substantial increase in permanent income for around 1.8 million women, on outcomes arguably related to women’s bargaining power within the household. We estimate the effects of the reform in the probability of divorce/separation, the distribution of household chores, and the probability of women being the head of the household, using a Difference-in-Differences approach. Our results show that despite the low divorce probability among seniors, transfers to senior women have substantial effects on their situation in the household. More specifically, we find that the reform had statistically significant effects on the probability of divorce/separation increasing it by 1.8 − 2.7 percentage points implying an increase of around 18 − 19% on the divorce/separation rate of 60 − 65 year old women. Moreover, the probability of being the head of the household also increased by 2.8−3.3 percentage points representing an increase of 7−19% in the probability amongst women of 60 − 65 years of age. In the case of married women, the probability of being the head of the household increased by 1.3 − 1.5 percentage points, which represents an increase of 20 − 22%. Results show that the distribution of household chores within the couples was also affected by the reform. More precisely, the probability that the wife is the only person in charge of the housework decreased by 5 percentage points, an 11% decrease. The participation of husbands in housework, however, did not change significantly.

El acceso a la telefonía móvil en Colombia evidencia ciertas particularidades con respecto a otros países. En Colombia surgió una nueva alternativa de comunicación que consistía en la venta de minutos de celular en las calles y en pequeños negocios durante los primeros años de ésta década. En este documento se analizan las principales características de quienes usan esta modalidad de comunicación con base en una encuesta dirigida a usuarios y no usuarios de bajos ingresos. Se usa un modelo probabilístico para explicar las características de las personas que lo usan y se encuentra que las personas que están en la modalidad de contrato prepago y que viven en ciudades pequeñas tienen una mayor probabilidad de usar esta alternativa de comunicación. De otro lado se encuentra que quienes están con el operador dominante tienden a usar este servicio también de una forma más notoria. Estos resultados parecen indicar que los diferenciales de precios entre las llamadas off-net y on-net así como entre prepago y postpago son los que alimentaron el surgimiento de esta actividad

This is a critical review of the empirical literature on the relationship between violence and economic growth in Colombia: an interesting case study for social scientists studying violence, conflict, crime and development. We argue that, despite the rapid development of this literature and the increasing use of new techniques, there is still much room for research. After assessing the contribution of the most influential papers on the subject, we suggest directions for future research.

In this paper we find that the diffusion pattern of mobile telephony in Colombia can be best characterised as following a Logistic curve. Although in recent years the rate of growth of mobile phone subscribers has started to slow down, we find evidence that there is still room for further expansion as the saturation level is expected to be reached in five years time. The estimated saturation level is consistent with some individuals possessing more than one mobile device.

Los datos recientes de areas de cultivos ilícitos indican que a pesar de las fumigaciones, la producción total se ha reducido levemente y los cultivos se han dispersado. Se plantea un modelo teórico que analiza las decisiones tomadas por los cultivadores sobre la localizaci´on de sus parcelas, basando esta escogencia en la dinamización local de los costos esperados. Se utiliza un modelo de agentes para la simulación de la naturaleza compleja de las dinámicas estudiadas. Se encuentra que el incentivo para agruparse aumenta con las economías a escala y se reduce con la expectativa del castigo, sobretodo en zonas con alta densidad de cultivadores.

This paper studies the effect of strengthening democracy, as captured by an increase in voting rights, on the incidence of violent civil conflict in nineteenth-century Colombia. Empirically studying the relationship between democracy and conflict is challenging, not only because of conceptual problems in defining and measuring democracy, but also because political institutions and violence are jointly determined. We take advantage of an experiment of history to examine the impact of one simple, measurable dimension of democracy (the size of the franchise) on con- flict, while at the same time attempting to overcome the identification problem. In 1853, Colombia established universal male suffrage. Using a simple difference-indifferences specification at the municipal level, we find that municipalities where more voters were enfranchised relative to their population experienced fewer violent political battles while the reform was in effect. The results are robust to including a number of additional controls. Moreover, we investigate the potential mechanisms driving the results. In particular, we look at which components of the proportion of new voters in 1853 explain the results, and we examine if results are stronger in places with more political competition and state capacity. We interpret our findings as suggesting that violence in nineteenth-century Colombia was a technology for political elites to compete for the rents from power, and that democracy constituted an alternative way to compete which substituted violence.

We carried out a randomized controlled trial in Bogotá, the recipient of Colombia´s highest number of internally displaced people (IDP), to assess whether the use of SMS to communicate eligibility to social benefits fosters the welfare of victimized internal refugees. Only a fraction of IDP are elegible to benefits. We inform eligibility via SMS to a random half of IDP-households who are, and estimate the Local Average Treatment Effect of the text message on the knowledge of the benefits available tothe displaced population. We show that while on the average treated households know their rights better than controls, a more disaggregate analysis suggest that there is variation of awareness across benefits. The intervention was overall successful in empowering IDP and the use of SMS should be widened as a social policy instrument. However our results suggest that text messages should be complemented with other communication strategies, yet to be evaluated.

This document aims to provide evidence about the existence of different patterns in equality of opportunities in academic achievement during the last fifteen years in Colombia. The outcomes selected for measuring inequality are the scores obtained on SABER 11 in math as well as reading. It is found that inequality has grown around 11% in the country, and that this trend is common for all the metropolitan areas included in the analysis. Most of the increase found comes from factors related to the school market. The fraction of unfair inequality, conditional to the circumstances included in the definition of “types”, is higher than 20% of gross inequality in 2012.

Financial protection is one of the objectives of health systems, which protects poor households from falling into poverty as a result of health care related expenses. Expanding prepayment schemes to the poor is difficult in developing countries because labor is largely informal. Providing health care free-at-point-of-service does not adequately target spending on the poorest, but occupation- or community-based schemes have also inherent limitations to achieve universal coverage. Colombia adopted a government-subsidized health insurance scheme (SHI) strategy. The political debate about increasing SHI enrollment needs evidence about the effectiveness of this scheme regarding financial protection. This study runs a four-part model to estimate the effect of SHI on out-of-pocket expenses by the poor that are currently uninsured, if they were enrolled in the SHI. The results show a 43% and 50% reduction in expenses at Bogotá and national level respectively, which confirms the effectiveness of SHI as a financial protection tool.

We offer a new explanation of partial risk sharing based on coalition formation and segmentation of society in a risky environment, without assuming limited commitment and imperfect information. Heterogenous individuals in a society freely choose with whom they will share risk. A partition belonging to the core of the membership game obtains. Perfect risk sharing does not necessarily arise. Focusing on mutual insurance rule and assuming that individuals only differ with respect to risk, we show that the core partition is homophily-based. The distribution of risk affects the number and size of these coalitions. Individuals may pay a lower risk premium in riskier societies. A higher heterogeneity in risk leads to a lower degree of risk sharing. We discuss how the endogenous partition of society into risk-sharing coalitions may shed light on empirical evidence on partial risk sharing. The case of heterogenous risk aversion leads to similar results.

El presente documento hace una revisión de la literatura reciente (últimos 15 años) que vincula la acción colectiva con las políticas públicas. En particular se observan dos tendencias, de un lado, la defensa a la lógica de la acción colectiva señalando el tipo de incentivos que se deben crear para propiciar la cooperación y eventualmente tener resultados de políticas públicas, y aquellos que piensan que la acción colectiva depende de elementos psicológicos y sociales que no siempre garantizan una cooperación constante y que dificultan predecir lo que puede suceder en términos de políticas públicas. Al final se concluye que, si bien la lógica de la acción colectiva contribuye al análisis de las políticas públicas, aún falta un mejor entendimiento de las razones que motivan o frenan la cooperación y la manera como esta se construye en función de un problema colectivo que se puede o no convertirse en una política pública.

Se evalúa el impacto redistributivo de las políticas educativas en Bogotá mediante el Análisis de Incidencia del Beneficio. A pesar que los hogares son autónomos con respecto a la elección entre la educación oficial y no oficial, la provisión pública de la educación genera fuertes impactos progresivos en el ingreso que se explayan hacia reducciones de pobreza y desigualdad, sin importar el cálculo del subsidio que se impute al ingreso.

Las deficiencias que registran los diferentes países de América Latina en los indicadores relacionados con el rendimiento escolar y la calidad educativa han sido un tema recurrente en la agenda política de los gobiernos de la región durante las últimas décadas. Diferentes estudios sugieren la incidencia de variables como la razón maestro/alumno, el gasto per cápita y la formación docente, entre otros. Sin embargo, se ha explorado muy poco la influencia de variables como la estructura organizacional, los sistemas de evaluación, los esquemas salariales y los incentivos, entre otros. Este trabajo pretende realizar una caracterización del desarrollo de estos aspectos para cuatro países de América Latina: Chile, México, Perú y Uruguay, en el marco de las reformas educativas emprendidas en los noventas. Adicionalmente se presenta un análisis de los principales resultados obtenidos hasta el momento, discriminados en dos tipos: la evolución de los salarios docentes y el mejoramiento en los resultados académicos de los estudiantes.

En la Conferencia Mundial de la Ciencia en Budapest se hizo un llamado para que la investigación científica y el desarrollo tecnológico esté más vinculado a resolver los problemas esenciales de la sociedad. Esta situación es lo que se conoce como el nuevo contrato social de la ciencia en donde los científicos se deben comprometer más a responder a las necesidades sociales y los gobiernos a apoyar la investigación.
