As redes secundárias de distribuição são item de extrema importância no processo de levar a energia produzida de uma fonte até o consumidor final. Dentro de uma Empresa Concessionária de Distribuição de Energia Elétrica o setor de planejamento, juntamente com o grupo técnico, deve realizar o planejamento dos investimentos necessários nos níveis de alta, média e baixa tensão, sendo que para a baixa tensão (redes secundárias de distribuição), normalmente utilizam-se os dados históricos e a média de investimentos dos últimos anos (de três a cinco últimos anos). Em geral não são encontrados nestas Empresas os cadastramentos das redes secundárias de distribuição ou então, quando estes existem, muitas vezes não são confiáveis. Neste ponto, esta dissertação de mestrado apresentará, aplicará e discutirá os resultados de uma metodologia de geração de redes secundárias de distribuição a partir dos dados das redes primárias de distribuição (média tensão) e dos ativos da Empresa, tendo como foco os investimentos necessários para estas dentro do planejamento agregado de investimentos. O trabalho proposto visa criar condições para que as Empresas enquadradas na situação anterior possam realizar o seu planejamento de baixa tensão valendo-se da aplicação de uma metodologia capaz de gerar tais redes. Uma vez criadas...

This article studies the impact of internal migration and remittance flows on wealth accumulation and distribution in 51 rural villages in Nang Rong, Thailand. Using data from 5,449 households, the study constructs indices of household productive and consumer assets with principal component analysis. The changes in these indices from 1994 to 2000 are modeled as a function of households’ prior migration and remittance behavior with ordinary least squares, matching, and instrumental variable methods. The findings show that rich households lose productive assets with migration, potentially because of a reduction in the labor force available to maintain local economic activities, while poor households gain productive assets. Regardless of wealth status, households do not gain or lose consumer assets with migration or remittances. These results suggest an equalizing effect of migration and remittances on wealth distribution in rural Thailand.; Sociology

Systematic information on household financial asset holdings in developing countries is very sparse. The author reviews some available data and current policy debates. Although financial asset holdings by households are highly concentrated, deeper financial systems are correlated with improved income distribution. For low-income countries, the relevant question for poor households is not how much financial assets they have, but whether they have any access to financial products at all. Building on and synthesizing disparate data collection efforts by others, the author produces new estimates of access percentages for over 150 countries. Across countries access is negatively correlated with poverty rates, but the correlation is not a robust one: thus the supposed anti-poverty potential of financial access remains econometrically elusive. Despite policy focus on the value of credit instruments, it is deposit products that tend to be the first to be used as prosperity increases, before more sophisticated savings products and borrowing.

This study presents the results of a survey and analysis of the data available on private participation in the power sector in the period 1990-2002, pointing to a series of preliminary findings, and identifies areas where deeper policy analysis is needed so that modalities for public-private partnerships can be proposed and the sector can again attract the needed investments. The final goal of this desk study is to select two or three countries for further analysis. It would be the objective of a subsequent phase, to analyze case studies and present key lessons learnt in selected countries and compare them with international experience.

This report reviews the evolution of the Indian power sector since the landmark Electricity Act of 2003 (EA 2003, or EA), with a focus on distribution as key to performance and viability of the sector. While all three segments of the power sector generation, transmission, and distribution are important, revenues originate with the customer at distribution, so subpar performance there hurts the entire value chain. Persistent operational and financial shortcomings in distribution have repeatedly led to central bailouts for the whole sector, even though power is a concurrent 1 subject under the Indian constitution and distribution is almost entirely under state control. Ominously, the recent sharp increase in private investment and market borrowing means power sector difficulties are more likely to spill over to lenders and affect the broader financial sector. Government-initiated reform efforts first focused on the generation and transmission segments, reflecting the urgent need for adding capacity and the complexity of issues to be addressed at the consumer interface. Consequently...

This section of the report aims to provide an analysis and propose specific technical plans for investment in the Juba distribution network to carry out emergency upgrades (as a short term measure) and to enable it to absorb possible power that is foreseen to be delivered from possible increase in supply (such as, through the Fula Rapids HPP). The report firstly explains the current Juba grid status, followed by the approach undertaken by the study. Then, it presents the result of gap analysis, concluding with the distribution investment plan and its necessary measures to achieve the target. It is to be noted that in the medium term, a detailed least cost investment plan (LCIP) for the country (planned under ESTAP) will be developed which will provide comprehensive methodology as well as an assessment of appropriate technical standards to be incorporated in development of the South Sudan electrical grid network.

How many and which firms issue equity and bonds in domestic and international markets, how do these firms grow relative to non-issuing firms, and how does firm performance vary along the firm size distribution? To evaluate these questions, a new data set is constructed by matching data on firm-level capital raising activity with balance sheet data for 45,527 listed firms in 51 countries. Three main patterns emerge from the analysis. (1) Only a few large firms issue equity or bonds, and among them a small subset has raised a large proportion of the funds raised during the 1990s and 2000s. (2) Issuers grow faster than non-issuers in assets, sales, and employment, that is, firms do not simply use securities markets to adjust their financial accounts. (3) The firm size distribution of issuers evolves differently from that of non-issuers, tightening among issuers and widening among non-issuers.

Der Beitrag stellt ausgewählte aktuelle Befunde zum Erbschafts- und Schenkungsgeschehen dar und analysiert den Einfluss von Erbschaften auf das Vermögen. Aus der Längschnittperspektive auf Basis des Sozio-oekonomischen Panels (SOEP) wird geklärt, wie weit die Vermögensübertragungen durch Erbschaften in Haushalten anfallen, die schon vorher ein beträchtliches Vermögen aufgebaut haben, und wie weit diese Erbschaften den Ausgangspunkt für die Vermögensbildung darstellen. Der Beitrag zeigt, dass eine Zunahme der Ungleichheit der Vermögensverteilung aufgrund des Erbschaftsgeschehens mit der in der Armuts- und Reichtumsforschung üblichen Methode relativer Ungleichheitsmaße nicht nachgewiesen werden kann. Die Ergebnisse weisen stattdessen darauf hin, dass Erbschaften auf die bestehende Vermögensverteilung tendenziell nivellierend wirken, weil Haushalte, die ohne Erbschaften über keinerlie Vermögen verfügen würden, erst dadurch überhaupt in die Lage versetzt werden, ein (wenn auch vielleicht geringes) Vermögen aufzubauen. Der Vermögenszuwachs durch Erbschaften bei der Gruppe der ohnehin bereits vermögenden Haushalte ist hingegen von relativ geringem Gewicht und führt daher auch nicht zu einer höheren Konzentration des Gesamtvermögens.; In this paper...

Approved for public release; distribution is unlimited; The concept of power has always been a complex term and debated by numerous academic schools. The end of the Cold War and the occurrence of a new multilateral international environment resulted not only in new power structures, but also in new problems and conflicts. Therefore, understanding the new power structures and evolving nature of international conflicts has become necessary in order to establish a stable and secure environment. Located in a geographical position where there are various types of conflict, Turkey stands as a leading figure, acting as both a regional soft power and an important contributor to peace operations. In this sense, this thesis explores the concepts of soft power and peacekeeping and the effects of Turkey’s soft-power assets, using peacekeeping operations in Afghanistan as a case study.; ; First Lieutenant, Turkish Army

In recent decades, many countries have embarked on structural reform programs involving private sector participation (PSP) across the entire value chain of the power sector. Often as part of a broader market oriented reform program, governments have resorted to PSP in transmission and distribution (T and D) for a variety of reasons, including to: (i) offset years of underinvestment and poor operating performance under public ownership; (ii) attract considerable private investment to fill the financing gap stemming from new T and D additions amid rapidly growing demand for electricity; and (iii) raise fiscal revenues by offloading state assets. In some cases (for example, Brazil and Peru), a prolonged electricity supply crisis prompted government into structural reforms of the T and D sector. The energy sector management assistance program (ESMAP) study covers PSP in transmission, as well as distribution. The four case-study countries, Brazil, Peru, Philippines, and Turkey were selected based on the substantial transmission story under their broader electricity PSP experience.

This paper examines the increasing participation of the private sector in the transmission and distribution of natural gas in developing countries during the 1990s, resulting mainly from the growing demand for new gas transport facilities coinciding with a growing consensus in favor of private participation in infrastructure. This note, drawing on the bank's PPI (Private Participation in Infrastructure) Project database, provides an overview of the patterns and trends in the projects in the twenty six developing countries which introduced private participation in natural gas between 1990 and 1997. It concludes with the thought that growth in privately funded and operated export projects promise s to bring the economic and environmental benefits of natural gas to a larger number of countries.

Infrastructure contributed just over one percentage point to Ghana's annual per capital GDP growth during the 2000s. Raising the country s infrastructure endowment to that of the region's middle-income countries could boost the annual growth rate by more than 2.7 percentage points. Ghana has an advanced infrastructure platform when compared with other low-income countries in Africa. The country s coverage levels for rural water, electricity, and GSM signals are impressive. A large share of the road network is in good or fair condition. Institutional reforms have been adopted in the ICT, ports, roads, and water supply sectors. Ghana s most pressing challenges lie in the power sector, where outmoded transmission and distribution assets, rapid demand growth, and periodic hydrological shocks leave the country reliant on high-cost oil-based generation. Exceptionally high losses in water distribution leave little to reach end customers, who are thus exposed to intermittent supplies. Addressing Ghana's infrastructure challenges will require raising annual expenditures to $2.3 billion. The country already spends about $1.2 billion per year on infrastructure...

With the recent resurgence of interest in equity, inequality, and growth, the possibility of a negative relationship between inequality and economic growth, has received renewed interest in the literature. Faced with the prospect that high levels of inequality may persist, and give rise to poverty traps, policymakers are paying more attention to the distributional implications of macroeconomic policies. Because high levels of inequality may hurt overall growth, policymakers are exploring measures to promote growth and equity at the same time. How the consequences of inequality are analyzed, along with the possible cures, depends partly on how inequality is measured. The authors use assets (land) rather than income - and a GMM estimator - to examine the robustness of the relationship between inequality and growth that has been observed in the cross-sectional literature, but has been drawn into question by recent studies using panel techniques. They find evidence that asset inequality - but not income inequality - has a relatively large negative impact on growth. They also find that a highly unequal distribution of assets reduces the effectiveness of educational interventions. This means that policymakers should be more concerned about households' access to assets...

One of the contentious issues in electricity reform is whether there are significant gains from restructuring systems that are moderately well run. South Africa's electricity system is a case in point. The sector's state-owned utility, Eskom, has been generating some of the lowest-priced electricity in the world, has largely achieved revenue adequacy, and has financed the bulk of the government's ambitious electrification program. Moreover, the key technical performance indicators of Eskom's generation plants have reached world-class levels. Yet the sector is confronted today with serious challenges. South Africa's electricity system is currently facing a tight demand/supply balance, and the distribution segment of the industry is in serious financial trouble. This paper provides a careful diagnostic assessment of the industry and identifies a range of policy and restructuring options to improve its performance. It suggests removing distribution from municipal control and privatizing it, calls for vertical and horizontal unbundling...

Uganda has made substantial progress on its infrastructure agenda in recent years. The early and successful ICT reform detonated a huge expansion in mobile coverage and penetration resulting in a highly competitive market. Power sector restructuring has paved the way for a rapid doubling of power generation capacity. Uganda is doing well on the water and sanitation MDGs, and has made effective use of performance contracting to improve utility performance. However, a number of important challenges remain. Despite reforms, the power sector continues to hemorrhage resources due to under-pricing and high distribution losses, while electrification rates are still very low. Providing adequate resources for road maintenance remains a challenge, and further investment is needed to increase rural connectivity and improve road safety. Addressing Uganda's infrastructure challenges will require sustained expenditure of around $1.4 billion per year over the next decade, strongly skewed towards capital expenditure. Uganda already spends approximately $1 billion per year on infrastructure...

During the 90s, most countries in Latin America and the Caribbean Region (LCR) supported by the World Bank, implemented a market-oriented reform in the energy sector to promote competition, economic regulation and greater private sector participation, as the main instruments to improve the quality, reliability and efficiency of energy services, and improve the government's fiscal position and increase affordable access to modern energy services for the poor. This report comprises an assessment of the energy sector reform in the region: its achievements, difficulties, lessons learnt and current status; an assessment of the future needs of the energy sector investment and financing requirements, constraints, and challenges; and a review of the role of development agencies in supporting the region's energy needs. The study is not a systematic analysis of the reform experience and needs of individual countries, which is not deemed necessary to define an energy strategy for the region, but rather an analysis of the main themes that are common to most countries...

This report provides some practical guidance on how utilities can define their own smart grid vision, identify priorities, and structure investment plans. While most of these strategic aspects apply to any area of the electricity grid, the document focuses on the segment of distribution. The guidance includes key building blocks that are needed to modernize the distribution grid and provides examples of grid modernization projects. Potential benefits that can be achieved (in monetary terms) for a given investment range are also discussed. The concept of the smart grid is relevant to any grid regardless of its stage of development. What varies are the magnitude and type of the incremental steps toward modernization that will be required to achieve a specific smart grid vision. Importantly, a utility that is at a relatively low level of grid modernization may leap frog one or more levels of modernization to achieve some of the benefits offered by the highest levels of grid modernization. Smart grids impact electric distribution systems significantly and sometimes more than any other part of the electric power grid. In developing countries...

This paper provides new evidence on the effect of pupil’s self-motivation and academic assets allocation on the academic achievement in sciences across countries. By using the Programme for International Student Assessment 2006 (PISA 2006) test we find that both explanatory variables have a positive effect on student’s performance. Self-motivation is measured through an instrument that allows us to avoid possible endogeneity problems. Quantile regression is used for analyzing the existence of different estimated coefficients over the distribution. It is found that both variables have different effect on academic performance depending on the pupil’s score. These findings support the importance of designing focalized programs for different populations, especially in terms of access to information and communication technologies such as internet.

O estudo objetivou analisar a relação entre distribuição de valor adicionado e nível de intangibilidade em empresas brasileiras listadas na BM&FBOVESPA. Para tal, realizou-se pesquisa descritiva, documental e quantitativa em uma amostra composta por 50 companhias dos diversos setores econômicos, com dados referentes ao exercício de 2011. Os resultados revelaram grandes desigualdades nos valores investidos em ativos intangíveis entre os setores. O setor econômico de petróleo, gás e biocombustíveis apresentou a maior média e a empresa que individualmente possuía o maior valor investido em intangíveis, destacando-se também em relação ao valor adicionado distribuído. As empresas listadas em níveis de governança corporativa considerados inferiores apresentaram maiores valores de ativos intangíveis e distribuíram quantidades maiores de valor adicionado. Os resultados obtidos permitiram concluir que, dentre as empresas analisadas, aquelas que possuíam maiores valores investidos em ativos intangíveis distribuíram maiores quantidades de valor adicionado.; The study aimed to analyze the relationship between value-added distribution and level of intangibility on Brazilian companies listed on the BM&FBOVESPA.
