Since its inception in 2006, the United Nations-backed Principles for Responsible Investment (PRI) have grown to over 1300 signatories representing over $45 trillion. This growth is not slowing down. In this paper, we argue that there is a set of attributes which make the PRI salient as a stakeholder and its claim to sign the six PRI important to institutional investors. We use Mitchell et al.’s (Acad Manag Rev 22:853–886, 1997) theoretical framework of stakeholder salience, as extended by Gifford (J Bus Eth 92:79–97, 2010). We use as evidence confidential data from the annual survey of signatories carried out by the PRI in a 5-year period between 2007 and 2011. The findings highlight pragmatic and organizational legitimacy, normative and utilitarian power, and management values as the attributes that contribute most to the salience of the PRI as a stakeholder.

Purpose – The purpose of this paper is to explore the role of the housing market in the monetary policy transmission to consumption among euro area member states. It has been argued that the housing market in one country is then important when its mortgage market is well developed. The countries in the euro area follow unitary monetary policy, however, their housing and mortgage markets show some heterogeneity, which may lead to different policy effects on aggregate consumption through the housing market. Design/methodology/approach – The housing market can act as a channel of monetary policy shocks to household consumption through changes in house prices and residential investment – the housing market channel. We estimate vector autoregressive models for each country and conduct a counterfactual analysis in order to disentangle the housing market channel and assess its importance across the euro area member states. Findings – We find little evidence for heterogeneity of the monetary policy transmission through house prices across the euro area countries. Housing market variations in the euro area seem to be better captured by changes in residential investment rather than by changes in house prices. As a result we do not find significantly large house price channels. For some of the countries however, we observe a monetary policy channel through residential investment. The existence of a housing channel may depend on institutional features of both the labour market or with institutional factors capturing the degree of household debt as is the LTV ratio. Originality/value – The study contributes to the existing literature by assessing whether a unitary monetary policy has a different impact on consumption across the euro area countries through their housing and mortgage markets. We disentangle monetary-policy-induced effects on consumption associated with variations on the housing markets due to either house price variations or residential investment changes. We show that the housing market can play a role in the monetary transmission mechanism even in countries with less developed mortgage markets through variations in residential investment.

”A stock market for all”. Integrity and concern for the market in the (self-)regulation of the Swedish securities market This article deals with the transformation process that led to the substantial growth of the securities markets, and also led to a situation where Sweden became one of the leading countries when it comes to ordinary people investing in shares and mutual funds. The article discusses how social control and regulation of the market changed as a result of this process. A sudden and strong unanimity for knowledge tests in order for a stockbroker to be allowed to conduct brokerage, advisory services and asset management was the significant change in this transformation process. Knowledge tests were first introduced on a voluntary basis by the industry itself, but is now a mandatory requirement by the State. This article argues that the unanimity for knowledge tests best can be understood by studying the broadening of the financial markets. The broadening meant that more groups in society – with very varying capabilities – had started to place their assets in the security markets. They were encouraged to do so since this was considered to be the solution to the growing number of socioeconomic problems. This article is mainly based on market statistics and document analysis supplemented by interviews.

Baby boomers and elderly care: expectations in print media about a new kind of care users The Swedish baby boomer generation – known as the forties generation – has been characterized as youthful and powerful. At present, members of this generation are entering the category of old age and in about ten years they will start reaching ages where the likelihood of encountering elderly care increases significantly. The present study reports on how this expected meeting has been discussed in Swedish newspapers. Data consisted of 481 articles during the period 1995–2012 and was analyzed through qualitative content analysis. Results show that the generation was predicted to become a new type of demanding and self-conscious care users. Claims were backed by descriptions of formative events and typical characteristics that were projected onto a future as care user. Such projections tended to portray care users of present time as passive and submissive, and partly responsible for problems associated with elderly care

The major objective of this paper is to identify, in the light of economic theory and of recent Brazilian and foreign institutional experiences, the best alternative for the reform of the regulatory framework of the domestic financial system, encompassing capital markets, insurance and private complementary social welfare. This paper is divided into four sections: in the first part, we identify the changes in the international and domestic financial systems, currently in an accelerated process of integration (search for similar rules and standards) and convergence (leveling of operational procedures). Next, we evaluate the potential impact of this new environment upon Brazilian economic development. In the second part, we analyze the concept of financial markets efficiency, where a contractualist view of the relationship involving suppliers and consumers of financial services is exposed. We also identify the major differences of focus among the several trends of regulation of the capital markets, insurance and private complementary social welfare In the third part, we present the concepts and the functions of a typical regulatory agency and alternative models of market regulation. In particular, we explore the differences between a regulatory model in which there are several regulatory agencies, each acting in segmented markets, as opposed to one in which there is single agency that regulates, supervises and oversees ali the indicated markets. In the forth and last part, we analyze the Brazilian case, attempting to identify, in the view of economic theory and recent experiences in other countries of the world, the best alternative for reforming present legislation. The basic recommended conclusion is to undertake studies that lead to the establishment of a single regulatory agency, congregating the functions currently performed by the Brazilian Securities Commission (CVM), the Superintendency of Private Insurance (Susep) and the Secretariai of Complementary Welfare (SPC).

Nos últimos tempos, mensurar o Risco Operacional (RO) tornou-se o grande desafio para instituições financeiras no mundo todo, principalmente com a implementação das regras de alocação de capital regulatório do Novo Acordo de Capital da Basiléia (NACB). No Brasil, ao final de 2004, o Banco Central (BACEN) estabeleceu um cronograma de metas e disponibilizou uma equipe responsável pela adaptação e implementação dessas regras no sistema financeiro nacional. A Federação de Bancos Brasileiros (FEBRABAN) também divulgou recente pesquisa de gestão de RO envolvendo vários bancos. Todo esse processo trouxe uma vasta e crescente pesquisa e atividades voltadas para a modelagem de RO no Brasil. Em nosso trabalho, medimos o impacto geral nos banco brasileiros, motivado pelas novas regras de alocação de capital de RO envolvendo os modelos mais básicos do NACB. Também introduzimos um modelo avançado de mensuração de risco, chamado Loss Data Distribution (LDA), que alguns especialistas, provenientes do Risco de Mercado, convencionaram chamar de Value-at-Risk Operacional (VaR Operacional.). Ao final desse trabalho apresentamos um caso prático baseado na implementação do LDA ou VaR

In this paper, we test a version of the conditional CAPM with respect to a local market portfolio, proxied by the Brazilian stock index during the period 1976-1992. We also test a conditional APT modeI by using the difference between the 3-day rate (Cdb) and the overnight rate as a second factor in addition to the market portfolio in order to capture the large inflation risk present during this period. The conditional CAPM and APT models are estimated by the Generalized Method of Moments (GMM) and tested on a set of size portfolios created from individual securities exchanged on the Brazilian markets. The inclusion of this second factor proves to be important for the appropriate pricing of the portfolios.

The aim of this paper is to assess the progress of the banking sector before and shortly after the Real Plan. We began by assessing the drop in the inflation revenues (negative real interest rates paid by the excess of demand deposits over total reserve requirements) as a result of the change in inflation from 40% a month for the pre-Real Plan period to a monthly average of 3.65% (IGP-DI), between July 1994 and May 1995. Then, using the financial statement data of a group of 90 banks, we attempt to estimate the net losses due to the inflation drop analyzing the profitability and other parameters of the banking industry. The calculations are made separately for private, state and federal banks. A later analysis on performance using information given to CVM (Securities Exchange Commission) by the six major private banks in the country is also discussed herein.

This paper attempts to explain why the Brazilian inter-bank interest rate is so high compared with rates practiced by other emerging economies. The interplay between the markets for bank reserves and government securities feeds into the inter-bank rate the risk premium of the Brazilian public debt.

Estimating the parameters of the instantaneous spot interest rate process is of crucial importance for pricing fixed income derivative securities. This paper presents an estimation for the parameters of the Gaussian interest rate model for pricing fixed income derivatives based on the term structure of volatility. We estimate the term structure of volatility for US treasury rates for the period 1983 - 1995, based on a history of yield curves. We estimate both conditional and first differences term structures of volatility and subsequently estimate the implied parameters of the Gaussian model with non-linear least squares estimation. Results for bond options illustrate the effects of differing parameters in pricing.

This paper analyzes the evolution of the protection to the minority stockholders of the stock market, through their right to withdrawal when the society is reorganized. Thus, a triple study was done: In the first place, it analyzes the evolution of legal protection for the minority stockholders with relation to possible abuses that can be committed by the majority stockholders of public traded corporations when there is a Public Offering for Stocks Acquisition (POSAs). In the second place, it studies opinions about this legal protection of portfolio managers and lawyers who deal with corporate law. Finally, it verified the POSAs which occurred in recent periods, comparing the values used by the majority stockholders to reimburse the stocks from minority shareholders in those POSAs. Comparing the results of these three above studies, we conclude that: A) The current legislation does not protect adequately the minority stockholders; B) There is a great dispersion of opinions among the two categories of professionals, concerning their approval or not of important details of the current legislation, and also of the old legislation; C) A great dispersion also exists about the suggestions concerning what should be modified in the legislation to improve it; D) The Brazilian Securities Commission (Comissão de Valores Mobiliários ¿ CVM) did not prevent the distortions observed in the POSAs studied; E) The legislation is not always well known by these professionals, and this suggests that the knowledge of small investors must be precarious. This insecurity and ignorance of the legal protection become obstacles for nonspecialized persons to invest in stocks, resulting in an important limitation for the development and popularization of the Brazilian stock market.

This study analyses the bids¿ dispersion in fixed income government securities auctions issued by the National Treasury of Brazil. We try to estimate the bids¿ variance based on factors that may forecast its movement. We hope to help the security issuer by offering more data before the auction. The basic idea is to relate the market uncertainty with the primary auction of government securities. Results indicates the importance of uncertainty on the bidding decisions. It shows also the need for a liquid secondary market to the selling of long-term fixed income securities.

Esta dissertação procurou identificar as diretrizes de supervisão dos mercados futuros no Brasil frente às práticas de regulação utilizadas em outros países do mundo, basicamente aqueles cujas economias e mercados são maiores do que o brasileiro, em volume de contratos negociados. O desenvolvimento do tema se deu de maneira a estimular o uso de tais práticas na estrutura local de supervisão, com vistas a uma melhoria da atividade dos órgãos reguladores e ao crescimento do mercado de capitais brasileiro. Dentre as referidas práticas, destacou-se a utilização de modelos estatísticos de precificação dos contratos negociados no sentido de balizar a atuação dos departamentos de fiscalização na investigação de condições artificiais de mercado. A abordagem desses modelos abrangeu desde a definição de conceitos fundamentais até a apresentação de um estudo de caso com opções sobre ações, passando pela caracterização dos principais modelos e formas de calcular a volatilidade no preço desses títulos. Os resultados de pesquisa foram relacionados às origens legais e ao desenvolvimento econômico recente do Brasil, que levaram à sofisticação dos mecanismos de financiamento do mercado de capitais nacional, não se limitando ao simples apontamento dos pontos fracos da estrutura local de supervisão. Finalmente, a pesquisa evoluiu para as necessidades práticas da atividade de supervisão a serem atendidas pelo regulador, segundo as características operacionais dos principais mercados, a fim de que a bolsa de futuros brasileira reforce sua posição competitiva no cenário mundial.

This work intends to study the relationship between Brazilian Internal Public Debt mix and Mutual Funds. In the theoretical framework, the discussion about liquidity preference theories implies considering risk averse investors. Portfolio selection is also discussed, particularly Markowitz efficient frontier. Historical data from November of 1999 to December of 2004 of Brazilian Internal Public Debt mix and Mutual Funds portfolio are analyzed. Official goals concerning Public Debt's mix and its actual composition are presented, as well as Mutual Fund preferences as buyers of public debt securities. Time series of three securities (LFT, LTN and NTN-C) in Public Debt mix and Mutual Funds portfolio are compared and a similar behavior is identified. Relevant facts of the macroeconomic context which may have affected Public Debt or Mutual Funds are discussed. Some indications of a possible influence of Mutual Funds upon Public Debt Mix are obtained and hypothesis to be tested in future studies are proposed.

Este trabalho está dividido em dois ensaios. O primeiro ensaio examina aspectos da liquidez do mercado secundário de títulos públicos no Brasil no período 2003 a 2006 e os determinantes do spread de compra e venda no mercado secundário de LTN - Letra do Tesouro Nacional no período 2005 a 2006. Os spreads foram calculados com base em dados diários de alta freqüência, para períodos de 30 minutos e de um dia. Em linhas gerais, a liquidez é um determinante importante no cálculo do spread. Especificamente os spreads diminuem quando os volumes ofertados aumentam. No caso dos prazos de vencimento, os spreads aumentam quando os prazos se ampliam. LTNs com prazos de vencimentos até 30 dias apresentaram spreads de 1 centavo de reais (1.89 bp) enquanto que LTNs com prazos acima de dois anos apresentaram spreads médios em torno de 54 centavos de reais (3.84 bp) para intervalos de 30 minutos e 81 centavos de reais (5.72 bp) para intervalos de um dia. Os testes econométricos foram realizados com base em um modelo apresentado por Chakravarty e Sarkar (1999) e aplicado ao mercado americano de bonds no período de 1995 e 1997. Os testes foram feitos utilizando-se a técnica do Método dos Momentos Generalizados (GMM). Os resultados confirmam o spread de compra e venda como medida importante no acompanhamento da liquidez. O segundo ensaio compara aspectos da liquidez e da microestrutura do mercado de títulos públicos em alguns paises como Brasil, Chile, México, Coréia, Singapura, Polônia e Estados Unidos. A análise utiliza algumas dimensões da microestrutura como a liquidez do mercado secundário (spread de compra e venda, giro do estoque de títulos e vencimentos mais negociados), os custos de eficiência, a estrutura e transparência do mercado primário e secundário e, por último, a segurança do mercado. O objetivo é comparar as características e o funcionamento dos mercados secundários desses paises e, confrontar com a realidade do mercado brasileiro face ao desenvolvimento da microestrutura. Apesar da falta de alongamento dos prazos dos títulos públicos, o mercado secundário no Brasil apresenta aspectos da microestrutura semelhantes aos paises em consideração o que sugere a existência de outros fatores fora a microestrutura que limitam o aumento dos prazos. Os resultados do primeiro ensaio ajudam nas comparações dos demais paises. Como resultado, encontramos que embora a liquidez do mercado secundário de títulos públicos no Brasil concentra-se em papéis de prazo menor, este fato provavelmente não se deve a questões de microestrutura do mercado.
