nÃo hà / Neste estudo à realizada, inicialmente, uma discussÃo teÃrica acerca da pobreza sob dois aspectos, monetÃria e multidimensional. Posteriormente, utilizou-se a metodologia desenvolvida por Alkire e Foster (2009) para analisar comparativamente, sob estas duas abordagens, a focalizaÃÃo do Programa Bolsa FamÃlia entre os domicÃlios cearenses, referente aos dados da PNAD 2012. Estimouse, tambÃm, dois modelos Logit visando identificar as caracterÃsticas socioeconÃmicas destes domicÃlios que contribuem para a classificaÃÃo como pobre por renda ou multidimensional. Constatou-se que, quando se considera a pobreza como um fenÃmeno multidimensional, a focalizaÃÃo do PBF à pior do que sob o aspecto renda. Observou-se, tambÃm, que cerca de 40% dos domicÃlios do Cearà sÃo pobres, independente da abordagem utilizada e que, quanto maior a populaÃÃo de crianÃas e/ou idosos no domicÃlio, mais vulnerÃvel este fica a vivenciar uma situaÃÃo de pobreza. / This research is initially based on a theoretical discussion about poverty in two aspects: monetary and multidimensional. Furthermore it was used Alkire and Foster methodology (2009) to analyze and compare the objectives of âBolsa Familiaâ amongst households in Ceara with regards to the PNAD 2012 data. It was also projected two Logit models to identify the socioeconomic characteristics of households that contribute to the classification of poor by income or multidimensional. It was found that , when considering poverty as a multidimensional phenomenon the focus of GMP is worse than under the income aspect . In addition it was estimated that about 40 % of Cearà 's households are poor regardless of the approach used and the higher the population of children and/or elderly at the domicile, the more vulnerable they are to experience a situation of poverty.

The increasingly observable excess capacity in the fixed networks calls into question the established long-standing pricing standards for wholesale services based on forward-looking long-run incremental costs (FL-LRAIC). The FL-LRAIC standard has worked quite well in expanding markets, although even there price-squeeze problems have appeared. In contracting markets the price-squeeze issue, however, becomes paramount and lower prices both at the wholesale and retail levels would be efficient. This would favor a retail-minus approach (RM) under long-term contraction. Because both expansion and contraction could be relevant in the future, we propose an optional approach based on the wholesale price formula p = min(FL-LRAIC, RM). This will generally protect alternative competitors against price-squeeze while at the same time allowing the fixed-network incumbent full downward price flexibility. It also protects alternative competitors and end users against excessively high prices. Hence, implementing this option successfully at wholesale level would eliminate the need to regulate retail markets. The combination of RM and FL-LRAIC seems to be most realistic, because it is relatively simple and internationally partly tested already. We show that this option is superior to FL-LRAIC or RM alone and to other approaches, such as short-run marginal costs. We also consider a possible combination with capacity-based charging, which may have particular merits for converged services in next generation networks (NGNs). / Series: Working Papers / Research Institute for Regulatory Economics
