Evaluating the equity effects of road-pricing in the European urban context - The Madrid Metropolitan Area

The paper identifies the potential spatial and social impacts of a proposed road-pricing scheme for different social groups in the Madrid Metropolitan Area (MMA). We appraise the accessibility of different districts within the MMA in terms of the actual and perceived cost of using the road infrastructure ‘before’ and ‘after’ implementation of the scheme. The appraisal framework was developed using quantitative survey data and qualitative focus group discussions with residents. We then simulated user behaviours (mode and route choice) based on the empirical evidence from a travel demand model for the MMA. The results from our simulation model demonstrated that implementation of the toll on the orbital metropolitan motorways (M40, M30, for example) decreases accessibility mostly in the districts where there are no viable public transport alternatives. Our specific study finding is that the economic burden of the road-pricing scheme particularly affects unskilled and lower income individuals living in the south of the MMA. The focus groups confirmed that low income drivers in the south part of the MMA would reduce their use of tolled roads and have to find new arrangements for these trips: i.e. switch to public transport, spend double the time travelling or stay at home. More generally, our research finds that European transport planners are still a long way from recognising the social equity implications of their policy decisions and that more thorough social appraisals are needed to avoid the social exclusion of low income populations when road tolling is proposed.

Evaluating the spatial and social equity effects of road pricing in the European urban context: the Madrid Metropolitan Area.

The paper explores the spatial and social impacts arising from implementation of a road-pricing scheme in the Madrid Metropolitan Area (MMA). Our analytical focus is on understanding the effects of the scheme on the transport accessibility of different social groups within the MMA. We define an evaluation framework to appraise the accessibility of different districts within the MMA in terms of the actual and perceived cost of using the road infrastructure "before" and "after" the implementation of the scheme. The framework was developed using quantitative survey data and qualitative data from focus group discussions with residents. We then simulated user behaviors (mode and route choice) based on the empirical evidence from a travel demand model for the MMA. The results from our simulation model demonstrated that implementation of the toll on the orbital metropolitan motorways (M40, M30, for example) decreases accessibility, mostly in the districts where there are no viable public transport alternatives. Our key finding is that the economic burden of the road-pricing scheme particularly affects unskilled and lower income individuals living in the south of the MMA. Consequently lower income people reduce their use of tolled roads and have to find new arrangements for these trips: i.e. switch to the public transport, spend double the time for their commuter trips or stay at home. The results of our research could be applicable more widely for anyone wishing to better understand the important relationship between increased transport cost and social equity, especially where there is an intention to introduce similar road-pricing schemes within the urban context.

How varies optimal welfare pricing with income distribution? The case of the untolled alternative

In some countries, such as Spain, it is very common that in the same corridor there are two roads with the same origin and destination but with some differences. The most important contrast is that one is a toll highway which offers a better quality than the parallel road in exchange of a price. The users decide if the price of the toll is worth paying for the advantages offered. This problem is known as the untolled alternative and it has been largely studied in the academic literature, particularly related to economic efficiency and the optimal welfare toll. However, there is a gap in the academic literature regarding how income distribution affects the optimal toll. The main objective of the paper is to fill this gap. In this paper a theoretical model is developed in order to obtain the optimal welfare price in a toll highway that competes with a conventional road for capturing the traffic. This model is done for non-usual users who decide over the expectation of free flow conditions. This model is finally applied to the variables we want to focus on: average value of travel time (VTT) which is strongly related with income, dispersion of this VTT and traffic levels, from free flow to congestion. Derived from the results, we conclude that the higher the average VTT the higher the optimal price, the higher the dispersion of this VTT the lower the optimal price and finally, the more the traffic the higher the optimal toll

ANÁLISE DAS MUDANÇAS DOS FATORES DETERMINANTES DA ESTRUTURA DE CAPITAL EM FUNÇÃO DO CICLO DE VIDA DAS EMPRESAS BRASILEIRAS

As várias teorias acerca da estrutura de capital despertam interesse motivando diversos estudos sobre o assunto sem, no entanto, ter um consenso. Outro tema aparentemente pouco explorado refere-se ao ciclo de vida das empresas e como ele pode influenciar a estrutura de capital. Este estudo teve como objetivo verificar quais determinantes possuem maior relevância no endividamento das empresas e se estes determinantes alteram-se dependendo do ciclo de vida da empresa apoiada pelas teorias Trade Off, Pecking Order e Teoria da Agência. Para alcançar o objetivo deste trabalho foi utilizado análise em painel de efeito fixo sendo a amostra composta por empresas brasileiras de capital aberto, com dados secundários disponíveis na Economática® no período de 2005 a 2013, utilizando-se os setores da BM&FBOVESPA. Como resultado principal destaca-se o mesmo comportamento entre a amostra geral, alto e baixo crescimento pelo endividamento contábil para o determinante Lucratividade apresentando uma relação negativa, e para os determinantes Oportunidade de Crescimento e Tamanho, estes com uma relação positiva. Para os grupos de alto e baixo crescimento alguns determinantes apresentaram resultados diferentes, como a singularidade que resultou significância nestes dois grupos, sendo positiva no baixo crescimento e negativa no alto crescimento, para o valor colateral dos ativos e benefício fiscal não dívida apresentaram significância apenas no grupo de baixo crescimento. Para o endividamento a valor de mercado foi observado significância para o Benefício fiscal não dívida e Singularidade. Este resultado reforça o argumento de que o ciclo de vida influência a estrutura de capital.

A SENSIBILIDADE CULTURAL DO ADVENTISMO COMO MODELO MISSIOLÓGICO EM GRANDES CENTROS URBANOS: UMA ANÁLISE DE IGREJAS ADVENTISTAS ÉTNICAS NA CIDADE DE SÃO PAULO

Esta pesquisa objetiva analisar o desenvolvimento da missão adventista na cidade de São Paulo em busca de um modelo missiológico para centros urbanos. São Paulo, uma das maiores metrópoles do mundo tem uma formação cultural plural, não apenas pelas forças atuantes da modernização, secularização, globalização e pós-modernidade. A composição da população da cidade possui uma gênese étnica plural. Além da matriz autóctone indígena, do colonizador branco europeu e dos escravos africanos, desde o início do século XIX chegaram outros imigrantes, europeus e asiáticos. Nas primeiras décadas do século XX, o Brasil foi o país que mais recebeu imigrantes em todo o mundo. Estima-se que nos anos de 1920, apenas um terço da população na cidade de São Paulo fosse de brasileiros, o restante era composto por imigrantes. A inserção do adventismo em São Paulo se deu por missionários imigrantes que trabalharam primeiro com outros imigrantes antes de evangelizar e desenvolver a missão adventista com os brasileiros nacionais. De alguma forma, esse início deixou marcas na missão adventista paulistana. São Paulo é hoje a cidade com o maior número total de adventistas no mundo e a única com Igrejas Adventistas étnicas que atendem cinco grupos étnicos distintos: japoneses, coreanos, judeus, árabes e bolivianos/peruanos. Esta pesquisa busca investigar a formação de uma sensibilidade cultural no adventismo paulistano que lhe permitiu dialogar com a pluralidade cultural da metrópole paulistana.

BigLaw Identity Capital: Pink and Blue, Black and White

This Article advances a new capital framework for understanding the bargain between large law firms and their lawyers, depicting BigLaw relationships not as basic labor-salary exchanges but rather as complex transactions in which large law firms and their lawyers exchange labor and various forms of capital — social, cultural, and identity. First, it builds on the work of Pierre Bourdieu regarding economic, cultural, symbolic, and social capital by examining the concepts of positive and negative capital, exploring the meaning of capital ownership by entities, and developing the notion of identity capital — the value individuals and institutions derive from their identities. Then, the Article advances a capital theory of BigLaw, in which large law firms and their lawyers engage in complex transactions trading labor, social, cultural, and identity capital for economic, social, cultural, and identity capital. Capital analysis sheds new light on the well-documented and troubling underrepresentation of diverse lawyers at BigLaw. It shows that the underrepresentation of women and minority lawyers is not solely the result of exogenous forces outside the control of large law firms such as implicit bias, but rather the outcome of the very exchanges in which BigLaw and its lawyers engage. Specifically, large law firms take into account the capital endowments of their lawyers in making hiring, retention and promotion decisions, and derive value from their lawyers’ capital, for example, by trading on the identity of women and minority lawyers in marketing themselves as being diverse and inclusive to clients and potential recruits. Yet, while BigLaw trades for the identity capital of women and minority lawyers, it fails to offer them opportunities in return to acquire the social and cultural capital necessary for attaining positions of power, resulting in underrepresentation. Moreover, these labor-capital exchanges are often implicit and made by uninformed participants, and therefore unjust. Exactly because the capital framework describes the underrepresentation of diverse lawyers at BigLaw as an endogenous outcome within the control of BigLaw and its lawyers, however, it is a cautiously optimistic model that offers hope for greater representation of diverse lawyers in positions of power and influence. The Article suggests policies and procedures BigLaw can and should adopt to improve the quality of the exchanges it offers to women and minority attorneys and to reduce the underrepresentation of diverse lawyers within its ranks. Employing the concepts of capital transparency, capital boundary, and capital infrastructure, it demonstrates how BigLaw can (1) explicitly recognize the roles social, cultural, and identity capital play in its hiring, retention and promotion apparatuses and (2) revise its policies and procedures to ensure that all of its lawyers have equal opportunities to develop the requisite capital and compete on equal and fair terms for positions of power and influence.

Risco de mercado na comercialização de energia elétrica: uma análise estruturada com foco no ambiente de contratação livre - ACL.

A motivação para o desenvolvimento desse trabalho surge em um momento em que se verifica uma participação cada vez mais significativa das fontes energéticas renováveis não convencionais no País. Não obstante, o cenário de evolução evidencia que o arcabouço regulatório e as regras de mercado não acompanharam as especificidades inerentes à exploração dessas fontes. Assim, para que se mantenha adequado ritmo de inserção na matriz energética, devem ser buscadas opções para que fontes alternativas sejam cada vez mais competitivas na atual configuração do mercado energético. A contribuição dessa pesquisa, portanto, centra-se na análise dos riscos de mercado incorridos por esses geradores de fontes intermitentes de energia ao comercializarem energia no ambiente de contratação livre. Nessa perspectiva, a Dissertação foi desenvolvida abordando tipos de geração de energia e suas características técnicas e econômicas, legislação do setor elétrico, regras de comercialização, balanço energético do sistema, formação de preços no mercado de curto prazo e precificação de contratos no ACL, diferença de preços entre submercados, requisitos de flexibilidade e sazonalidade nos contratos de venda a consumidores livres e seu impacto na precificação de contratos, identificação de comportamento energético complementar para mitigação de riscos de mercado entre fontes renováveis e rebatimento na formulação de mecanismo de hedge, análise de portfólio de contratos e estratégia ótima de contratação de energia para agentes geradores atuando no ACL. Como resposta ao desafio de equacionar o impasse surgido na comercialização de fontes de produção sazonal, propõe-se um modelo para definir estratégias de contratação para agentes geradores e comercializadores a partir da complementação energética entre diferentes tipos de fontes, de forma a maximizar os ganhos de comercialização para um risco estabelecido. Busca-se a composição ideal dessas fontes na carteira de um comercializador para minimizar o risco de exposição à volatilidade dos preços do mercado de curto prazo. Isso é possível em virtude das compensações energéticas feitas entre as diferentes fontes em um portfólio combinado, mitigando a receita em risco decorrente das variações que existem nos preços de curto prazo e na produção energética. De forma complementar, estruturou-se um modelo de negócio no qual uma empresa detentora de ativos de geração hidrelétrica compra os direitos de produção de uma eólica e/ou biomassa para incorporar ao seu portfólio e vender como contrato por quantidade. Determinou-se o volume de energia a ser comprado de cada fonte, o preço, a estratégia mais indicada de contratação e a mitigação de fatores de risco contemplados nos contratos de venda, buscando maximizar os ganhos de comercialização condicionada a critérios de risco pré-fixados.

Legislative Proposals to Modernize Business Development Companies and Expand Investment Opportunities, Testimony Before the House Subcommittee on Capital Markets and Government Sponsored Enterprises

This testimony discusses proposed legislation to amend the definition of accredited investor. It also discusses proposed legislation designed to reform the regulatory framework for business development companies. Among other things, the regulatory regime for BDCs would change to allow these companies to invest a greater portion of their assets in financial companies, potentially reducing the percentage of assets invested in operating companies.

Hiring Manager Training for Strategically Selecting the Best Human Capital

The selection process is arguably the most important part of the employee life cycle in an organization, but a process often underdeveloped in many organizations. Successful selection processes can put the right people into critical positions, whereas failure to focus on selection can result in poor performance, turnover, and loss of productivity critical to the continuing success of organizations. This paper creates a model for a hiring manager training that focuses on a strategic selection process to maximize chances for successful hires. Utilizing leadership and selection models, human resources can engage hiring managers in a strategic applicant selection process as well as give tools for screening, interviewing, and selecting the best candidates for employment throughout all levels of their organization.

MINLP Model for the Synthesis of Heat Exchanger Networks with Handling Pressure of Process Streams

This paper introduces a new mathematical model for the simultaneous synthesis of heat exchanger networks (HENs), wherein the handling pressure of process streams is used to enhance the heat integration. The proposed approach combines generalized disjunctive programming (GDP) and mixed-integer nonlinear programming (MINLP) formulation, in order to minimize the total annualized cost composed by operational and capital expenses. A multi-stage superstructure is developed for the HEN synthesis, assuming constant heat capacity flow rates and isothermal mixing, and allowing for streams splits. In this model, the pressure and temperature of streams must be treated as optimization variables, increasing further the complexity and difficulty to solve the problem. In addition, the model allows for coupling of compressors and turbines to save energy. A case study is performed to verify the accuracy of the proposed model. In this example, the optimal integration between the heat and work decreases the need for thermal utilities in the HEN design. As a result, the total annualized cost is also reduced due to the decrease in the operational expenses related to the heating and cooling of the streams.

Percepción, activos intangibles y stakeholders: modelo para el análisis de imagen corporativa

El presente artículo abordará aproximaciones para la gestión de la imagen corporativa; pensada como un activo intangible que proyecta la institución. Además, se consideran diversos modelos y conceptos de capital intelectual que identifican factores relevantes hacia la toma decisión por parte de stakeholders. La percepción de imagen es un tema que ha suscitado interés por parte de instituciones, pues ésta se encuentra estrechamente vinculada a la formación integral de una idea que influye en el desarrollo de una actitud favorable o no hacia la reputación corporativa. De esta manera, los clientes, consumidores, proveedores, colaboradores, entre otros; reciben a través de distintas formas elementos que le ayudan a conformar una idea sobre la institución mediante sus percepciones; por lo que, orientar los esfuerzos y acciones en torno a este intangible, dará como resultado una rentabilidad no sólo monetaria sino una fidelidad y confianza por parte de sus stakeholders. Es así, que se ha visto la necesidad de proponer un modelo para el análisis de la imagen corporativa de instituciones, el mismo que consta de cinco categorías las cuales poseen parámetros de puntuación, construidos a partir de los aportes de diferentes autores.

International Capital Flows and Monetary Policy Spillovers

This dissertation examines the drivers and implications of international capital flows. The overarching motivation is the observation that countries not at the centre of global financial markets are subject to considerable spillovers from centre countries, notably from their monetary policy. I present new empirical evidence on the determinants of the observed patterns of international capital flows and monetary policy spillovers, and study their effect on both financial markets and the real economy. In Chapter 2 I provide evidence on the determinants of a puzzling negative correlation observed between productivity growth and net capital inflows to developing and emerging market economies (EMEs) since 1980. By disaggregating net capital inflows into their gross components, I show that this negative correlation is explained by capital outflows related to purchases of very liquid assets from the fastest growing countries. My results suggest a desire for international portfolio diversification in liquid assets by fast growing countries is driving much of the original puzzle. In the reminder of my dissertation I pivot to study the foreign characteristics that drive international capital flows and monetary policy spillovers, with a particular focus on the role of unconventional monetary policy in the United States (U.S.). In Chapter 3 I show that a significant portion of the heterogeneity in EMEs' asset price adjustment following the quantitative easing operations by the Federal Reserve (the Fed) during 2008-2014 can be explained by the degree of bilateral capital market frictions between these countries and the U.S. This is true even after accounting for capital controls, exchange rate regimes, and domestic monetary policies. Chapter 4, co-authored with Michal Ksawery Popiel, studies unconventional monetary policy in a small open economy, looking specifically at the case of Canada since the global financial crisis. We quantify the effect Canadian unconventional monetary policy shocks had on the real economy, while carefully controlling for and quantifying spillovers from U.S. unconventional monetary policy. Our results indicate that the Bank of Canada's unconventional monetary policy increased Canadian output significantly from 2009-2010, but that spillovers from the Fed's policy were even more important for increasing Canadian output after 2008.

A Viable Alternative to Basel III Prudential Capital Rules. CEPS Policy Brief No. 291, May 2013

Stefano Micossi argues in this paper that the Basel framework for bank prudential requirements is deeply flawed and that the Basel III revision has failed to correct these flaws, making the system even more complicated, opaque and open to manipulation. In practice, he finds that the present system does not offer regulators and financial markets a reliable capital standard for banks and its divergent implementation in the main jurisdictions of the European Union and the United States has broken the market into special fiefdoms governed by national regulators in response to untoward special interests. The time is ripe to stop tinkering with minor adjustment and revisions in order to rescue the system, because the system cannot be rescued. In response to the current situation, Micossi calls for abandoning reference to risk-weighted assets calculated by banks with their internal risk management models for the determination of banks’ prudential capital, together with the preoccupation with the asset side of banks in correcting for risk exposure. He suggests that the alternative may be provided by a combination of a straight capital ratio and a properly designed deposit insurance system. It is a logical, complete and much less distortive alternative; it would serve better the cause of financial stability as well as the interest of the banks in clear, transparent and level playing field.

The Asset Quality Review and Capital Needs: Why re-capitalise banks with public money? CEPS Policy Brief No. 311, 19 December 2013

It is generally assumed that any capital needs discovered by the Asset Quality Review the ECB is scheduled to finish by the end of 2014 should be filled by public funding (= fiscal backstop). This assumption is wrong, however. Banks that do not have enough capital should be asked to obtain it from the market; or be restructured using the procedures and rules recently agreed. The Directorate-General for Competition at the European Commission should be particularly vigilant to ensure that no further state aid flows to an already oversized European banking system. The case for a public backstop was strong when the entire euro area banking system was under stress, but this is no longer the case. Banks with a viable business model can find capital; those without should be closed because any public-sector re-capitalisation would likely mean throwing good money after bad.

Farm-level Capital: Capital positions, structures, the dynamics of farm-level investments, capital accumulation and leverage positions. Factor Markets Working Paper No. 7, October 2011

This Factor Markets Working Paper describes and highlights the key issues of farm capital structures, the dynamics of investments and accumulation of farm capital, and the financial leverage and borrowing rates on farms in selected European countries. Data collected from the Farm Account Data Network (FADN) suggest that the European farming sector uses quite different farm business strategies, capabilities to generate capital revenues, and segmented agricultural loan market regimes. Such diverse business strategies have substantial, and perhaps more substantial than expected, implications for the financial leverage and performance of farms. Different countries adopt different approaches to evaluating agricultural assets, or the agricultural asset markets simply differ substantially depending on the country in question. This has implications for most of the financial indicators. In those countries that have seen rapidly increasing asset prices at the margin, which were revised accordingly in the accounting systems for the whole stock of assets, firm values increased significantly, even though the firms had been disinvesting. If there is an asset price bubble and it bursts, there may be serious knock-on effects for some countries.
