Divisia indexes, money and welfare

We suggest the use of a particular Divisia index for measuring welfare losses due to interest rate wedges and in‡ation. Compared to the existing options in the literature: i) when the demands for the monetary assets are known, closed-form solutions for the welfare measures can be obtained at a relatively lower algebraic cost; ii) less demanding integrability conditions allow for the recovery of welfare measures from a larger class of demand systems and; iii) when the demand speci…cations are not known, using an index number entitles the researcher to rank di¤erent vectors of opportunity costs directly from market observations. We use two examples to illustrate the method.

Sustainability indexes: why join in? A study of the Corporate Sustainability Index (ISE) in Brazil

In the past decade, indicators have been created to assess the sustainability performance of companies listed in stock exchange markets. Academics and practitioners expect companies to benefit from being listed in such indexes, but evidence of value creation is still scarce. Since virtually all studies about the Corporate Sustainability Index (ISE) of the S~ ao Paulo Stock Exchange (Brazil) e the object of the present study e focused on the value of shares, we initially looked for answers in the finance theory. We collected secondary data about the financial and economic performance of companies forming the ISE's ‘theoretical portfolio’, as these kinds of indexes are also known. In a second stage, we sought additional motivations for companies to make efforts to be listed in the index. We collected additional data and interviewed representatives of key companies listed in the ISE, as well as industry leaders who chose not to participate in the selection process. The results support the main propositions of the institutional theory, as well as the ‘pays to be green’ literature e that the intangible value created by voluntary environmental initiatives, such as access to knowledge, new capabilities and reputational gain, better explain the efforts companies make to be listed in the ISE index

The diversity of diversity: further methodological considerations on the use of the concept in cultural economics

The implications of diversity still raise confusion in the cultural debate. We address them from both a formal and conceptual viewpoints, putting in check the validity of some arguments. We conclude that: measuring diversity demands key decisions and careful statistical procedures; ignorance on optimal diversity levels and on ways to generate them is widespread in the cultural field; there is no support for cultural diversity as something associated to fair economic and political systems; restriction to sheer economics requires the establishment of links between diversity and measurable properties – something rather incipient. Diversity, as a social choice, should be distinguished from it as an economic value.

Productive restructuring: effects on Brazilian regional development distribution

This paper aims to evaluate the dynamics of Brazilian regional development during the 1985-95 period. First, regional inequalities indexes were calculated for the whole country’s economy based on the per capita regional income (Williamson Inequality Index), in order to test the convergence or divergence. After this, the analysis aimed to verify the sector and regional dynamics in a more detailed exam, and for this purpose Dispersion Quotients and Dispersion Intensity Coefficients were calculated based on two variables, the Regional Gross Domestic Product and the Working Population. The results of the analysis confirm the existence of considerable regional disparities and it was verified that the sector and regional redistribution of the GDP indicate that, in a general way, no remarkable changes occurred in the regional productive structures in the period. It is also inferred that the economic policy at that period, in spite of resulting in a global regional convergence process of the per capita product, did not avoid the continuation of the concentration of greater economic dynamism in the most advanced regions, nor did it diminish in any considerable way the difference in the degree of development of the Northeast region.

Productivity of nations: a stochastic frontier approach to TFP decomposition

This Paper Tackles the Problem of Aggregate Tfp Measurement Using Stochastic Frontier Analysis (Sfa). Data From Penn World Table 6.1 are Used to Estimate a World Production Frontier For a Sample of 75 Countries Over a Long Period (1950-2000) Taking Advantage of the Model Offered By Battese and Coelli (1992). We Also Apply the Decomposition of Tfp Suggested By Bauer (1990) and Kumbhakar (2000) to a Smaller Sample of 36 Countries Over the Period 1970-2000 in Order to Evaluate the Effects of Changes in Efficiency (Technical and Allocative), Scale Effects and Technical Change. This Allows Us to Analyze the Role of Productivity and Its Components in Economic Growth of Developed and Developing Nations in Addition to the Importance of Factor Accumulation. Although not Much Explored in the Study of Economic Growth, Frontier Techniques Seem to Be of Particular Interest For That Purpose Since the Separation of Efficiency Effects and Technical Change Has a Direct Interpretation in Terms of the Catch-Up Debate. The Estimated Technical Efficiency Scores Reveal the Efficiency of Nations in the Production of Non Tradable Goods Since the Gdp Series Used is Ppp-Adjusted. We Also Provide a Second Set of Efficiency Scores Corrected in Order to Reveal Efficiency in the Production of Tradable Goods and Rank Them. When Compared to the Rankings of Productivity Indexes Offered By Non-Frontier Studies of Hall and Jones (1996) and Islam (1995) Our Ranking Shows a Somewhat More Intuitive Order of Countries. Rankings of the Technical Change and Scale Effects Components of Tfp Change are Also Very Intuitive. We Also Show That Productivity is Responsible For Virtually All the Differences of Performance Between Developed and Developing Countries in Terms of Rates of Growth of Income Per Worker. More Important, We Find That Changes in Allocative Efficiency Play a Crucial Role in Explaining Differences in the Productivity of Developed and Developing Nations, Even Larger Than the One Played By the Technology Gap

Diversificação e performance - uma análise das estratégias de diversificação em empresas brasileiras

Este trabalho visa explorar, com base em dados brasileiros, a relação entre diversificação e performance. Como medida de performance serão utilizados valores correspondentes ao índice q de Tobin para empresas de capital aberto. Para o cálculo do índice de diversificação de uma firma serão utilizados índices compostos a partir da codificação americana SIC (Standard Industry Code). A verificação da relação estatística entre diversificação e performance será então aferida através da aplicação de modelos de regressão linear e sistemas de equações estruturais simultâneas.

Estudo dos gastos e investimentos em informática: avaliação, evolução e tendências nas médias e grandes empresas

"Estudo dos Gastos e Investimentos em Informática" - Estudo que quantifica os gastos e investimentos em informática e analisa a sua evolução nos últimos dez anos para identificar seu comportamento e suas tendências. os valores são estudados por meio de dois índices: o gasto total (investimentos e despesas) como uma percentagem do faturamento líquido da empresa e o custo anual por teclado. Ambos são indicadores oumedidas com um uso crescente e que podem ter umpapel fundamental na moderna administração da tecnologia da Informação. Os dados levantados vão até o início de 1999 para 1.141 empresas médias e grandes que atuam no Brasil. O estudo retrata a evolução, analisa o comportamento e demonstra que os índices dependem do setor da economia e do nível de informatização da empresa.

Modelagem do potencial de mercado dos municípios paulistas

Os indicadores de potencial de consumo são medidas indiretas da capacidade de uma região absorver uma determinada categoria de produto. O método de regressão linear simples pode ser utilizado na elaboração de índices simples e robustos que geralmente produzem resultados comparáveis ou superiores aos que podem ser obtidos pela utilização de índices vendidos por empresas de consultoria. Este fato passa despercebido pela maioria dos usuários porque habitualmente não são feitos esforços de comparar os índices com a realidade que estes se propõem a descrever (o que tem uma certa lógica, porque se conhecêssemos a realidade não precisaríamos do índice de potencial). Para estabelecer a metodologia e demonstrar a tese acima, são coletados dados a respeito da área de loja de supermercados dos municípios do Estado de São Paulo; um índice é construído, e em seguida comparado com outros indicadores. Os resultados confirmam a suposição inicial.

Regiões metropolitanas brasileiras: índices de diferenciação

The research investigates the differences among Brazilian metropolitan regions, in what concerns to the composition of their productive and occupational structures. This investigation aims to allow the observation of the differentiated stages of metropolitan development, in comparing the spaces among themselves and in measuring the intensity of the differences. This work intends to subsidize the analysis of the private and public firms location choices, and on the other hand, to point out the necessities of public intervention aiming regional development. The analysis is accomplished with the help of differentiation regional indexes, calculated from information aggregated in special tabulations, in order to accomplish the specifics objectives of this research.

A democratização do acesso ao ensino superior: um estudo sobre o Programa Universidade Para Todos (PROUNI) e sobre o sistema de reservas de cotas de vagas étnico-raciais

Brazil is an extremely unequal country and this inequality has been a permanent characteristic of its economic and social structure. Some scholars generally consider that the economic growth has generated extreme conditions of space and social inequalities, which reveal themselves within Brazil¿s regions, states, rural and urban areas, central and peripheral areas and among its ethnic groups. Such conditions negatively affect the quality of life of the population and will be reflected in the reduction of life expectancy, in the increase of the indexes of infant mortality and illiteracy, amongst other aspects. Education is considered one of the ways to promote the development of a country, however, access to education, specially higher education in Brazil, since it was first implemented, had been limited to a small group of privileged people, the elite of society. Thus, it becomes necessary to extend the access of students to higher education and consequently to generate individuals capable of changing the reality of the place where they live in and as a result, to develop the country. The purpose of this research is to analyze two programs destined to the amplify the access to higher education in Brazil, namely, the University for All Program (ProUni) and the System of Quotas, with the objective to verify at which level their drawings and strategies will allow the democratization of the access to higher education and the reduction of regional inequalities. In order to achieve its objective, the study is initiated with the issue of development and inequalities in Brazil, then it goes through the history of higher education in Brazil and it is finished with the analysis of ProUni and the System of Quotas.

O project finance no financiamento de empreendimentos em saneamento básico no Brasil

A situação atual dos sistemas de saneamento básico no Brasil, bem como o quadro regulatório e institucional do setor, são o resultado de conturbados antecedentes e de políticas descontínuas, determinadas por aspectos conjunturais e pela alternância entre momentos de maior e menor disponibilidade de recursos. A privatização e a concessão de serviços oferece perspectivas concretas de redefinição da trajetória de evolução do setor, com o estabelecimento de um padrão mais constante e regular de crescimento dos índices de cobertura e de modernização dos sistemas e das técnicas de gestão. A lógica do investimento privado implica na orientação pelo lucro e na configuração de estruturas de menor risco para os recursos comprometidos com o empreendimento. O project finance é uma técnica de financiamento que permite a repartição de riscos entre os participantes, reduzindo parcelas individuais e, conseqüentemente, agregando maior atratividade ao negócio. O presente estudo terá por objetivo analisar o setor de saneamento básico e o project finance, buscando identificar as possibilidades e os impactos presumíveis da introdução e difusão da técnica como alternativa de financiamento para o setor no Brasil.

A logística militar e o serviço de intendência: uma análise do programa excelência gerencial do Exército Brasileiro

This study has the purpose to analyze some of the programs and measures adopted by the Brazilian Army, as well as eventual contributions, for the modernization of its Logistics. Thus, focus one of the main devices of logistic support of the Forces, the Quartermaster, approaching some roles performed by this Service that comprises the current conception of the Army Logistics. This modernization process is mainly developed through a excellence program implemented for the whole Army aiming, amongst other factors, the adoption of managerial practices leading to a better operational performance and to the improvement of the Institution' services and products quality: the Managerial Excellence Program of the Brazilian Army (PEG-EB). Here, the Logistics is deemed as key part for the organizational success and one of the main factors of competitive differential of companies, directly related to costs reduction and increase in the level of services provided for the customers. For the Army, the improvement and update of logistic doctrine emerge as priority for achieving the goals, especially focusing the need to integrated the logistics activities, in order to optimize the resources available, reduce costs and prioritize its actions. While searching for an integrated approach for its logistics, the Army created a central body with the responsibility to coordinate all the supply chain of its Units: the Logistic Department (D Log). This body centrally coordinates a major segment of logistics functions in the Forces. The conclusion states that the development of this mentality about the internal integration of activities will allow a rationalization of the management process, increasing the indexes of availability of material from military organizations, and consequently a serviceability gain for the Brazilian Army.
