Este trabalho procura aprofundar o estudo de anomalias ao CAPM no mercado acionário brasileiro e explorar as relações destas anomalias com a característica dificuldade financeira, a qual é representada pela classificação de risco das empresas, usando estratégias de compra e venda a descoberto baseadas nas anomalias. As anomalias estudadas serão o efeito de momento, momento nos lucros, a volatilidade idiossincrática, o crescimento dos ativos, o investimento em capital e o efeito contrário. Nosso objetivo é examinar o impacto da característica dificuldade financeira sobre o retorno esperado das ações de empresas do grupo de menor classificação de risco. Para cumprir nosso objetivo, inicialmente usamos todas as ações da Bolsa de Valores de São Paulo (Bovespa) para comparar estas com a amostra de empresas que possuem classificação de crédito de longo prazo. O período estudado é de Janeiro de 2000 a Dezembro de 2012. Os métodos usados foram baseados em ordenação de carteiras e regressões univariadas e multivariadas de corte transversal. Encontramos algumas evidências de que empresas com classificação de crédito sugerem retornos anormais diferentes daqueles da amostra de todas as empresas. Este resultado foi significante...

O reúso de software enfrenta inúmeras barreiras gerenciais, técnicas e culturais na sua adoção, e a definição da estrutura de ativos reutilizáveis de software é uma dessas barreiras técnicas. Para solucionar isso, o Reusable Asset Specification (RAS) é um padrão de facto proposto pela OMG. Uma especificação como o RAS define e padroniza um modelo de ativos (assets) reutilizáveis, e é a base para a construção e para o uso de um repositório de ativos que apoia a reutilização de software. No entanto, para ser adotado na prática, o RAS necessita resolver suas lacunas através da sua extensão e da definição de informações complementares. Essas lacunas estão detalhadas neste trabalho. Solucionando estas lacunas, o RAS torna-se útil para auxiliar efetivamente na padronização do empacotamento dos ativos reutilizáveis e para guiar a estrutura do repositório de reutilização de software. Alguns trabalhos anteriores já responderam parcialmente essa questão, porém eles atendiam propósitos muito específicos, não possuíam uma ferramenta de apoio ou não haviam sido avaliados em contexto real de (re)uso. Esse trabalho propõe o Software Profile RAS (SW-RAS), uma extensão do Profile de componentes do RAS, que propõe soluções para diversas de suas lacunas...

Tese de mestrado integrado em Engenharia da Energia e do Ambiente, apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2012; Economic development in the last decades was characterized by oil-based energy production. The finite nature of the natural resources and the environmental impact of his production and consumption alerted the world for the necessity of change of these premises .One of the sectors that contribute with a high percentage of the global consumption of energy in the European Union is the buildings sector (40 %). So, in 2010, the 2002/91/CE Directive was reformed, creating the 2010/31/EU Directive, what was promoting the improvement of the energetic performance of the buildings in the community and which introduces new concepts: nearly zero-energy building (nZEB), minimum energy performance requirements and the cost optimal. This new directive reinforces the need of energy certification, in order to promote the more energy efficient buildings. Energy performance certification considers two base methods: asset rating (nominal conditions) and operational rating (operating method). This dissertation goal was a comparative study of the different methodologies of energy performance classification for office buildings in the regulation revision context (RSECE). This study was carried out for two office buildings with different constructive features and located in different regions. Another of the introduced concepts in the new Directive is it of the optimized profit level. In this dissertation...

This publication provides a comprehensive overview of topics related to the assessment, analysis, and management of various types of risks in the field of Islamic banking. It is an attempt to provide a high-level framework (aimed at non-specialist executives) attuned to the current realities of changing economies and Islamic financial markets. The Islamic financial system is not limited to banking; it also covers capital formation, capital markets, and all types of financial intermediation and risk transfer. Islamic finance was practiced predominantly in the Muslim world throughout the middle ages, fostering trade and business activities with the development of credit. The growth of Islamic finance coincided with the current account surpluses of oil-exporting Islamic countries. The Middle East saw a mushrooming of small commercial banks competing for surplus funds. The Islamic Republics of Iran, Pakistan, and Sudan announced their intention to make their financial systems compliant with Shariah.

The Financial Sector Assessment Program (FSAP) update team found that the authorities have progressed in implementing the key recommendations from the initial assessment. The 2005 FSAP team revealed a number of vulnerabilities, including (i) high credit growth, largely financed by foreign banks, which resulted in rising nonperforming loans (NPLs), and (ii) poor management and low capital of several systematically important state-controlled banks. The Basel Core Principle on Banking Supervision (BCP) assessment identified a number of deficiencies in banking supervision. The update team found that the authorities took action to address the issues highlighted by the 2005 FSAP. In particular, they adopted prudential measures to slow credit growth, including higher risk weights for foreign currency loans to un-hedged borrowers, and exposure limits to households. Two systemic state-controlled banks were privatized. Finally, a new banking law was enacted that significantly strengthened supervision on consolidated basis and improved corporate governance and transparency.

This report concerns the Financial Sector Advisory Centreapos;s (FinSAC) attempt to shed light on the regulations and practices in the areas of identifying and provisioning for loans losses in 26 countries in the Emerging Europe and Central Asia (ECA) region. FinSAC aims to deliver policy and technical advice and analytical services to client ECA countries. This reportapos;s analysis is based on a World Bank Survey conducted from 2011 to 2012 on banking supervision. Even though it is often stated that Non Performing Loans (NPL) ratios and provisions are not easily comparable across jurisdictions, NPLs and their provisions in the European and Central Asian (ECA) region are frequently charted and analyzed across multiple jurisdictions. As a result of the lack of harmonized regulations in this area, concerns regarding the consistency of loan quality assessments are frequently raised, particularly with respect to the distinction between performing and non performing exposures, provisions for non performing exposures...

Bank loans can become non-performing because of problems with the borrower s financial health, problems with the design or implementation of lender protection features, or both. In ascertaining how to deal with a problem loan, it is important to distinguish between a borrower s ability to pay and willingness to pay, Making this distinction is not always easy and requires effort. This manual was written as a guide for lending institution staff dealing with non-performing loans (NPLs) extended to corporations and small and medium enterprises (SMEs). It deals with both ad hoc and systemic financial distress and delves into how borrower problems may have arisen in the first place. It provides guidance to lending institutions staff responsible for handling individual problem loans and to senior managers responsible for organizing portfolio-wide asset resolution.

A plethora of recent literature on asset pricing provides plenty of empirical evidence on the importance of liquidity, governance and adverse selection of equity on pricing of assets together with more traditional factors such as market beta and the Fama-French factors. However, literature has usually stressed that these factors are priced individually. In this dissertation we argue that these factors may be related to each other, hence not only individual but also joint tests of their significance is called for. In the three related essays, we examine the liquidity premium in the context of the finer three-digit SIC industry classification, joint importance of liquidity and governance factors as well as governance and adverse selection. Recent studies by Core, Guay and Rusticus (2006) and Ben-Rephael, Kadan and Wohl (2010) find that governance and liquidity premiums are dwindling in the last few years. One reason could be that liquidity is very unevenly distributed across industries. This could affect the interpretation of prior liquidity studies. Thus, in the first chapter we analyze the relation of industry clustering and liquidity risk following a finer industry classification suggested by Johnson, Moorman and Sorescu (2009). In the second chapter...

Não existe uma definição única de processo de memória de longo prazo. Esse processo é geralmente definido como uma série que possui um correlograma decaindo lentamente ou um espectro infinito de frequência zero. Também se refere que uma série com tal propriedade é caracterizada pela dependência a longo prazo e por não periódicos ciclos longos, ou que essa característica descreve a estrutura de correlação de uma série de longos desfasamentos ou que é convencionalmente expressa em termos do declínio da lei-potência da função auto-covariância. O interesse crescente da investigação internacional no aprofundamento do tema é justificado pela procura de um melhor entendimento da natureza dinâmica das séries temporais dos preços dos ativos financeiros. Em primeiro lugar, a falta de consistência entre os resultados reclama novos estudos e a utilização de várias metodologias complementares. Em segundo lugar, a confirmação de processos de memória longa tem implicações relevantes ao nível da (1) modelação teórica e econométrica (i.e., dos modelos martingale de preços e das regras técnicas de negociação), (2) dos testes estatísticos aos modelos de equilíbrio e avaliação, (3) das decisões ótimas de consumo / poupança e de portefólio e (4) da medição de eficiência e racionalidade.

This assessment of Moldova current state of compliance with the Basel core principles for effective banking supervision (BCPs) was undertaken as part of a joint International Monetary Fund (IMF) - World Bank mission in connection with a broader financial sector assessment program exercise. This version of the assessment has a greater focus on risk management policies and practices implemented by supervised institutions and their assessment by the supervisory authority as well as more emphasis on quality implementation of supervisory standards. The assessment has been conducted in accordance with the revised BCP assessment methodology approved by the Basel committee and was based on extensive discussions with officers and staff members of the Banking Supervision Department in National Bank of Moldova (NBM), and a review of internal supervisory documents, such as manuals, operating policies, examination reports, and external audit reports. The mission reviewed the BCP self-assessment undertaken by NBM preceding this assessment...

Countries that have experienced banking crises have adopted one of two distinct approaches toward the resolution of non-performing assets-a centralized or a decentralized solution. A centralized approach entails setting up a government agency-an asset management company-with the full responsibility for acquiring, restructuring, and selling of the assets. A decentralized approach relies on banks and other creditors to manage and resolve non-performing assets. The authors study banking crises where governments adopted a decentralized, creditor-led workout strategy following systemic crises. They use a case study approach and analyze seven banking crises in which governments mainly relied on banks to resolve non-performing assets. The study suggests that out of the seven cases, only Chile, Norway, and Poland successfully restructured their corporate sectors with companies attaining viable financial structures. The analysis underscores that as in the case of a centralized strategy the prerequisites for a successful decentralized restructuring strategy are manifold. The successful countries significantly improved the banking system's capital position...

This report reviews loan classification and provisioning practices in a broad sample of countries that differ in size, location and level of financial development. The survey conducted for the report compares the regulatory approaches adopted by industrial and emerging economies, and is intended to complement other sources of information that focus exclusively on either industrial or developing countries. It covers classification of individual and multiple loans, treatment of guarantees, collateral and restructured loans, bank loans review processes, loan loss provisioning, tax treatment of loan loss provisions, disclosure standards, and external auditors' role. Differences in provisioning and classification approaches have often made difficult a comparison of bank and banking system weaknesses across regulatory regimes. Poor classification and provisioning practices have led to solvency ratios that gave a false sense of security, as occurred when seemingly adequately capitalized financial systems failed in the 1990s. Successful regulatory harmonization therefore requires a set of minimum standards for loan classification that is grounded in sound risk management practices...

Financial intermediation in Tajikistan has deepened in recent years, albeit from a low base. This is reflected in the overall growth of the financial system, greater diversification, and the expansion of lending to previously under-served sectors, such as agriculture and small- and medium-sized enterprises. Even after the expansion, however, the financial sector remains small and cannot serve all the financing needs of the economy. While banks are generally well capitalized and liquid, their rapid growth has brought new risk exposures that should be carefully monitored and appropriately addressed. In particular, rapid loan growth could lead to a build-up of unrecognized credit risk and give rise to an increase in non-performing loans (NPLs). Because of extensive dollarization, the exposure of banks to exchange-rate induced credit risk is another significant cause for concern. Also, the exceptionally rapid growth of nonresident deposits without clear knowledge of their sources exposes the banking system to reputational risk. Significant strengthening of the regulatory and supervisory framework will be needed to sustain the system's health in the face of rapid growth. Governance in the financial sector needs significant strengthening. Improvements are needed to ensure the integrity of the regulatory bodies and to guarantee that all financial transactions are conducted at arms' length and priced on a market basis. Fair and transparent resolution of the large stock of distressed cotton debt would demonstrate the government's commitment to market principles and good governance.

The Kazakhstan financial sector remains dominated by domestic commercial banks. The banking sector is largely domestically owned, private, and relatively concentrated, with the largest five banks accounting for 78 percent of total banking assets. The share of foreign banks has increased to about 15 percent of total banking assets after some recent acquisitions. The stress testing included single factor sensibility and scenario analysis and focused on the potential impacts of the two main risks being faced by the banking system, liquidity and credit risks. The exercise looked into the potential impact of: (i) the ongoing liquidity crunch and worsening external funding conditions; and (ii) asset and collateral quality deterioration, particularly for construction, real estate, and consumer lending. Some progress has been achieved in strengthening the prudential framework and improving bank governance. However, there is a need to move towards risk-based supervision with more attention to banks' use of risk management systems and internal controls...

Despite the global and domestic shocks of 2008-2009, the banking sector remains sound. Salvadoran banks were not directly exposed to the global financial crisis. However, the parent banks of several major Salvadoran banks were and directed subsidiaries to conserve risk capital. The higher risk aversion and recession in the United States, combined with uncertainty about the 2009 elections, led to a sharp economic downturn, and a decline in both credit demand and supply. Banks' nonperforming loans increased and profitability declined. Even so, capitalization remained high. Stress tests indicate that most banks would be able to withstand large deposit withdraws and severe deterioration in credit quality arising from large macroeconomic or sectoral shocks. However, credit concentration risks appear significant. Regulated non-bank financial institutions do not pose significant risks, but pension funds' poor profitability is a concern for the long-term. Regulated cooperative banks and insurance companies report healthy financial indicators. Brokerage houses have reduced drastically their fund management activities...

Global growth is projected to pick up to 3.4 percent in 2015 and 3.5 percent in 2016, propelled by highincome countries. Developing country growth will benefit from these tailwinds, with growth projected to increase from 4.8 percent in 2014 to 5.5 percent in 2016 broadly in line with potential. Global growth projections for 2014, however, have been marked down from 3.2 percent to 2.8 percent on account of the bumpy start this year, buffeted by poor weather in the United States, financial market turbulence and the conflict in Ukraine. The outlook for the East Asia and the Pacific region continues to reflect several counterbalancing factors, including domestic policy adjustment, volatile financing conditions, political crisis in Thailand, and sustained recovery in global demand for exports. Regional GDP growth is expected to slow down slightly to 7.0 percent by 2016, about 2 percentage points slower than the pre-crisis boom years but broadly in line with potential. Regional risks include volatility and eventual tightening of global financing conditions...

In a standard hold-up problem, individuals are vulnerable to hold-up because it is impossible to write complete contracts to cover the lifespan of relationship-specific investments. Hold-up occurs only when investments are to some degree nongeneric, and the extent of the problem increases with the time-span over which an investment must pay off, since long-term contracts are more difficult to write than short-term contracts. This result appears inconsistent with the real life experience of contract suppliers in two respects. First, suppliers often consider themselves "vulnerable" to hold-up even when investments are generic. Second, such a sense of vulnerability is often greatest precisely when assets are short-lived rather than long-lived. This paper provides a model that solves this apparent paradox by looking beyond the isolated problem of bilateral monopoly to the market context in which contracting takes place. We then find that the very meaning of asset specificity comes into question.
