El objetivo de esta tesis es determinar a traves de un diagnostico mixto ?cual es la situacion actual de pobreza en Villapinzon?, con el fin de identificar areas prioritarias de intervencion y proponer preliminarmente alternativas para avanzar en la superacion de pobreza en el municipio. Este diagnostico se desarrollo a partir de una metodologia mixta. El componente cualitativo se realizo durante los meses de julio y octubre de 2012, a traves de cuatro fases de investigacion: I) visitas previas; II) observacion participante; III) grupos focales y IV) entrevistas. El componente cuantitativo incluye el calculo de i) la incidencia de pobreza multidimensional en Villapinzon; ii) la incidencia ajustada de pobreza multidimensional; iii) el calculo de la brecha de pobreza ajustada y iv) un analisis multivariado. Estas aproximaciones permitieron identificar nuevas dimensiones y tendencias que no habrian sido reconocidas si los fenomenos multidimensionales de pobreza hubieran sido analizados de manera aislada con una sola metodologia. Esta tesis se aproximo a una nueva medicion de pobreza en el nivel local, que a partir de fuentes primarias y secundarias (calculo a partir del Sisben), genero una nueva vision de las condiciones de vida y de pobreza de los villapinzonenses. Finalmente, se proponen intervenciones en areas prioritarias: educacion, vivienda, trabajo y dinamica familiar. Las recomendaciones aqui enunciadas son un punto de partida, y sugieren futuras lineas de investigacion, analisis de politica e intervenciones dentro del municipio. \u0000English Abstract This study explores poverty as a multidimensional phenomenon in a small municipality in Colombia. To do so, we employ a mixed method design that aims to explore poverty combining both quantitative and qualitative research techniques. The purpose is to identify and operationalize the dimensions of the Multidimensional Poverty Index (MPI). We also aim to identify potential intervention areas that can contribute to the social policy agenda of the local authorities in this Colombian village. The MPI-Colombia measures five dimensions: household education conditions; childhood and youth conditions; labor; health and access to household utilities and living conditions. The methodological approach allowed us to identify new dimensions and risk factors that would not have been recognized if multidimensional poverty phenomena have been analyzed in isolation. The qualitative component was conducted through four phases of research: I) pre-study research, II) participant observation, III) focus groups and IV) interviews. The quantitative component estimates I) the Multidimensional Headcount Ratio; II) the Adjusted Headcount Ratio, III) the Adjusted Poverty Gap and IV) a multivariate an","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125155439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have considered the interplay between community characteristics and individual-level variables. This study examines the influence of community education and family socioeconomic characteristics on child health (as measured by height and weight-for-age Z-scores), as well as their interactions. We adapted the Commission on Social Determinants of Health (CSDH) framework to the context of child health. Using data from the 2010 Colombian Demographic and Health Survey (DHS), weighted multilevel models are fitted since the data are not self-weighting. The results show a positive impact of the level of education of other women in the community on child health, even after controlling for individual and family socioeconomic characteristics. Different pathways through which community education can substitute for the effect of family characteristics on child nutrition are found. The interaction terms highlight the importance of community education as a moderator of the impact of the mother’s own education and autonomy, on child health. In addition, the results reveal differences between height and weight-for-age indicators in their responsiveness to individual and contextual factors. Our findings suggest that community intervention programmes may have differential effects on child health. Therefore, their identification can contribute to a better targeting of child care policies.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130241740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, the relatively high incomes achieved by countries in Latin America have ruled them out as partners for development cooperation. However, 30% of its population still lives under the poverty level, while both income disparity and rural-urban disparity remain high, which point to a high demand for development cooperation. Therefore this study conducted a quantitative analysis to identify priority sectors and suggest sectoral plans for the official development aid (ODA) toward Latin American countries. This study is composed of six chapters. Following the introductory chapter, chapter two analyzes the environment for development cooperation of the Latin American region.

The extent of inequality reduction induced by direct taxes and transfers is rather small (2 percentage points on average) especially when compared with that found in Western Europe (15 percentage points on average). What prevents Argentina, Bolivia and Brazil from achieving similar reductions in inequality is not the lack of revenues but the fact that they spend less on cash transfers especially transfers that are progressive in absolute terms - as a share of GDP. Indirect taxes result in that net contributors to the fiscal system start at the fourth, third and even second decile on average, depending on the country. When in-kind transfers in education and health are added, however, the bottom six deciles are net recipients. The impact of transfers on inequality and poverty reduction could be higher if spending on direct cash transfers that are progressive in absolute terms is increased, leakages to the nonpoor are reduced and coverage of the extreme poor by direct transfer programs is expanded.","PeriodicalId":324969,"journal":{"name":"ERN: Latin America & the Caribbean (Development) (Topic)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131726115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
