Business life cycle and capital structure: evidence from Chinese manufacturing firms

This paper uses a panel data-fixed effect approach and data collected from Chinese public manufacturing firms between 1999 and 2011 to investigate the impacts of business life cycle stages on capital structure. We find that cash flow patterns capture more information on business life cycle stages than firm age and have a stronger impact on capital structure decision-making. We also find that the adjustment speed of capital structure varies significantly across life cycle stages and that non-sequential transitions over life cycle stages play an important role in the determination of capital structure. Our study indicates that it is important for policy-makers to ensure that products and financial markets are well-balanced.

Accounting quality, information risk and implied volatility around earnings announcements

We examine the impact of accounting quality, used as a proxy for information risk, on the behavior of equity implied volatility around quarterly earnings announcements. Using US data during 1996–2010, we observe that lower (higher) accounting quality significantly relates to higher (lower) levels of implied volatility (IV) around announcements. Worse accounting quality is further associated with a significant increase in IV before announcements, and is found to relate to a larger resolution in IV after the announcement has taken place. We interpret our findings as indicative of information risk having a significant impact on implied volatility behavior around earnings announcements.

Housing provision in 21st century Europe

European housing markets exhibited considerable volatility so far in the 21st century while affordability worsened for many. Boom-bust has had greater housing impacts than any specific housing policy, which illustrates the difficulty in policy terms of seeing housing in isolation and the central significance of interlinked relationships between housing, the economy and financial markets. Europe historically invented a powerful set of interventionist tools to alter housing circumstances but, as the overview of rental markets here indicates, today they have mixed success. Examples of what to avoid in policy are at least as common as exemplars.

STABILITY ANALYSIS WITH APPLICATIONS OF A TWO-DIMENSIONAL DYNAMICAL SYSTEM ARISING FROM A STOCHASTIC MODEL FOR AN ASSET MARKET

We analyze the stability properties of equilibrium solutions and periodicity of orbits in a two-dimensional dynamical system whose orbits mimic the evolution of the price of an asset and the excess demand for that asset. The construction of the system is grounded upon a heterogeneous interacting agent model for a single risky asset market. An advantage of this construction procedure is that the resulting dynamical system becomes a macroscopic market model which mirrors the market quantities and qualities that would typically be taken into account solely at the microscopic level of modeling. The system`s parameters correspond to: (a) the proportion of speculators in a market; (b) the traders` speculative trend; (c) the degree of heterogeneity of idiosyncratic evaluations of the market agents with respect to the asset`s fundamental value; and (d) the strength of the feedback of the population excess demand on the asset price update increment. This correspondence allows us to employ our results in order to infer plausible causes for the emergence of price and demand fluctuations in a real asset market. The employment of dynamical systems for studying evolution of stochastic models of socio-economic phenomena is quite usual in the area of heterogeneous interacting agent models. However, in the vast majority of the cases present in the literature, these dynamical systems are one-dimensional. Our work is among the few in the area that construct and study analytically a two-dimensional dynamical system and apply it for explanation of socio-economic phenomena.

Short-time behaviour of demand and price viewed through an exactly solvable model for heterogeneous interacting market agents

We introduce a stochastic heterogeneous interacting-agent model for the short-time non-equilibrium evolution of excess demand and price in a stylized asset market. We consider a combination of social interaction within peer groups and individually heterogeneous fundamentalist trading decisions which take into account the market price and the perceived fundamental value of the asset. The resulting excess demand is coupled to the market price. Rigorous analysis reveals that this feedback may lead to price oscillations, a single bounce, or monotonic price behaviour. The model is a rare example of an analytically tractable interacting-agent model which allows LIS to deduce in detail the origin of these different collective patterns. For a natural choice of initial distribution, the results are independent of the graph structure that models the peer network of agents whose decisions influence each other. (C) 2009 Elsevier B.V.

”En aktiemarknad för alla” : Integritet och marknadsomsorg i (själv)regleringen av den svenska värdepappersmarknaden

”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.

A reconstrução do marco regulatório do sistema financeiro do Brasil: os mercados de capitais, de seguros e previdência privada

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).

Fatores críticos de sucesso na corretagem de ações pela internet na visão do investidor: um estudo exploratório

The aim of this study is to investigate, under the perspective of the investor, the determinant factors for the success of the stock brokerage process over the Web, through financial portals in the Brazilian Internet. This study is based on a theoretical framework which shows the evolution of the electronic commerce all over the world, and, specially, in Brazil; analyses the role of intermediation, desintermediation and reintermediation in the electronic commerce; stresses the differences between the traditional stocks brokerage process and the one made possible by the Internet; and, finally, describes the profile of the investors which operates their investments in the financial markets over the Web.The conclusions of this study are obtained based on a field study, conducted with Brazilian investors that operate using Internet based financial portals for the intermediation of their stock operations. The findings obtained where analyzed under the perspective brought by the theoretical reference framework, and, based on this approach, the critical aspects for the success of stock brokerage over the Internet, under the vision of the investor, could be deducted and discussed.

Contabilidade governamental brasileira no contexto da convergência aos padrões internacionais

With the globalization of the economy and the growing participation of several world investors in financial markets, combining the political, economical and social differences of each country, the varying Accounting Statements based on principles, standards, procedures or idiosyncratic accounting patterns become inadequate to provide comprehensible and useful financial information to the users at international level. Considering a country¿s conditions, peculiarities and the stage of development, the need to promote the convergence of the effective accounting practices in the public sector with the emerging international accounting standards is imperative as the public entities endeavor to provide transparent and comparable accounting information that can be understood by financial analysts, investors, auditors and other users, independent of their origin and location. Consequently, the objective of this research was described through the following questions: Which are the main differences between the international and local accounting norms applicable to the public sector in Brazil? Which are the main differences between the applicable international accounting norms and the practices adopted by the Brazilian public sector? And, which are the main differences between the practices adopted by the entities of the Brazilian public sector and the practices adopted by entities of the public sector of countries that formally follow the international accounting norms? The methodology adopted in this research was the one of comparative analysis between standards and practices. To provide a basis for the comparative analysis, the Brazilian standards were used for the public sector and the international standards were identified by consulting with the main international accounting committees. In the comparative analyses of norms adopted in national accounting statements the financial accounting statements of the Municipal districts of Rio de Janeiro and of São Paulo were used, and compared with the international accounting statements of New Zealand. The results of these comparative analyses provide important conclusions about the convergence and harmonization processes in accounting norms and practices for the public sector mainly as they demonstrate some of the conflicts among the recent efforts to base and harmonize accounting practices in the near future, but today significant differences remain between the norms and practices. It was also noticed that, in practice, the divergence in Brazilian accounting practices from the international standards are accentuated by the recognition of the registrations of the budgetary execution in the patrimonial accounting; and, the comparison with the practices adopted by New Zealand demonstrated that the foreign country¿s advances towards harmonizing its standards to the international norms and practices in such an important way that New Zealand independently overcomes the minimum exigencies of harmonization, which in practice, is more complete than the practices currently adopted in Brazil.

O efeito manada nos fundos de investimento no Brasil: um teste em finanças comportamentais

Utilizando-se de uma amostra de movimentações diárias de fundos de investimento em ações, multimercados e renda fixa no Brasil, por meio de uma metodologia baseada na direção das captações líquidas de um grande número de fundos de investimento, agregados em grupos de investidores de acordo com o porte médio de seu investimento (ricos e pobres), foi encontrada forte evidência da ocorrência de efeito manada de forma heterogênea entre diferentes grupos de investidores, sendo que a intensidade do efeito manada varia de acordo com o porte do investidor, tipo de fundo e com a época. Também foi testado um viés de heurística: a ancoragem de preço, que supõe que após uma nova máxima ou mínima histórica nos preços das ações, haverá uma movimentação anormal de investidores, que acreditam ser este evento um indicador sobre os preços futuros. Encontrou-se evidência de que este fenômeno ocorre em diferentes tipos de fundos de investimento, não apenas os fundos de investimento em ações, e que tem maior impacto quando há uma nova mínima do que quando há uma cotação recorde no índice Ibovespa. Entretanto, o poder de explicação deste viés sobre o efeito manada é pequeno, e há uma série de variáveis ainda não exploradas que têm maior poder de explicação sobre o efeito manada. Desta maneira, este estudo encontrou evidências de que os pressupostos de finanças comportamentais de que a informação e as expectativas dos investidores não são homogêneas, e que os investidores são influenciáveis pelas decisões de outros investidores, estão corretos, mas que há fraca evidência que o viés de heurística de ancoragem de preço tenha papel relevante no comportamento dos investidores.

Essays in corporate risk management

This research investigates the factors that lead Latin American non-financial firms to manage risks using derivatives. The main focus is on currency risk management. With this purpose, this thesis is divided into an introduction and two main chapters, which have been written as stand-alone papers. The first paper describes the results of a survey on derivatives usage and risk management responded by the CFOs of 74 Brazilian non-financial firms listed at the São Paulo Stock Exchange (BOVESPA), and the main evidence found is: i) larger firms are more likely to use financial derivatives; ii) foreign exchange risk is the most managed with derivatives; iii) Brazilian managers are more concerned with legal and institutional aspects in using derivatives, such as the taxation and accounting treatment of these instruments, than with issues related to implementing and maintaining a risk management program using derivatives. The second paper studies the determinants of risk management with derivatives in four Latin American countries (Argentina, Brazil, Chile and Mexico). I investigate not only the decision of whether to use financial derivatives or not, but also the magnitude of risk management, measured by the notional value of outstanding derivatives contracts. This is the first study, to the best of my knowledge, to use derivatives holdings information in emerging markets. The use of a multi-country setting allows the analysis of institutional and economic factors, such as foreign currency indebtedness, the high volatility of exchange rates, the instability of political and institutional framework and the development of financial markets, which are issues of second-order importance in developed markets. The main contribution of the second paper is on the understanding of the relationship among currency derivatives usage, foreign debt and the sensitivity of operational earnings to currency fluctuations in Latin American countries. Unlikely previous findings for US firms, my evidence shows that derivatives held by Latin American firms are capable of producing cash flows comparable to financial expenses and investments, showing that derivatives are key instruments in their risk management strategies. It is also the first work to show strong and robust evidence that firms that benefit from local currency devaluation (e.g. exporters) have a natural currency hedge for foreign debt that allows them to bear higher levels of debt in foreign currency. This implies that firms under this revenue-cost structure require lower levels of hedging with derivatives. The findings also provide evidence that large firms are more likely to use derivatives, but the magnitude of derivatives holdings seems to be unrelated to the size of the firm, consistent with findings for US firms.

Endogenous debt constraints in collateralized economies with default penalties

In infinite horizon financial markets economies, competitive equilibria fail to exist if one does not impose restrictions on agents' trades that rule out Ponzi schemes. When there is limited commitment and collateral repossession is the unique default punishment, Araujo, Páscoa and Torres-Martínez (2002) proved that Ponzi schemes are ruled out without imposing any exogenous/endogenous debt constraints on agents' trades. Recently Páscoa and Seghir (2009) have shown that this positive result is not robust to the presence of additional default punishments. They provide several examples showing that, in the absence of debt constraints, harsh default penalties may induce agents to run Ponzi schemes that jeopardize equilibrium existence. The objective of this paper is to close a theoretical gap in the literature by identifying endogenous borrowing constraints that rule out Ponzi schemes and ensure existence of equilibria in a model with limited commitment and (possible) default. We appropriately modify the definition of finitely effective debt constraints, introduced by Levine and Zame (1996) (see also Levine and Zame (2002)), to encompass models with limited commitment, default penalties and collateral. Along this line, we introduce in the setting of Araujo, Páscoa and Torres-Martínez (2002), Kubler and Schmedders (2003) and Páscoa and Seghir (2009) the concept of actions with finite equivalent payoffs. We show that, independently of the level of default penalties, restricting plans to have finite equivalent payoffs rules out Ponzi schemes and guarantees the existence of an equilibrium that is compatible with the minimal ability to borrow and lend that we expect in our model. An interesting feature of our debt constraints is that they give rise to budget sets that coincide with the standard budget sets of economies having a collateral structure but no penalties (as defined in Araujo, Páscoa and Torres-Martínez (2002)). This illustrates the hidden relation between finitely effective debt constraints and collateral requirements.

Targeting the poor: a macroeconomic analysis of cash transfer programs

This paper introduces cash transfers targeting the poor in an incomplete markets model with heterogeneous agents facing idiosyncratic risk. These transfers change the degree of insurance in the economy and affect precautionary motives asymmetrically, leading the poorest households to decrease savings proportionally more than their richer counterparts. In a model economy calibrated to Brazil, once the cash transfer program is adopted, wealth inequality and social welfare increase, poverty decreases, while employment and income inequality remain about the same. Imperfect access to financial markets is important for these results, whereas whether the program is funded with lump sum or distortive taxes is not.

O impacto da utilização da estrutura de listagem em BDR na precificação dos ativos após o evento Agrenco : uma análise em série temporal com quebra estrutural

Este trabalho tem por objetivo verificar o impacto que más práticas na gestão da Agrenco, empresa listada na bolsa de valores brasileira sob a forma de BDRs (Brazilian Depositary Receipts), trouxe para a precificação dos demais ativos listados sob a mesma estrutura. Estudos anteriores, como os de Saudagaran (1988) e Pagano (2001), focaram em temas referentes aos motivos que influenciaram as companhias a listarem suas ações em diferentes bolsas. Entender as conseqüências do evento Agrenco é importante para todos os participantes do mercado financeiro. O estudo contemplou uma amostra das principais empresas listadas sobre a forma de BDRs desde a data de seus IPOs até 26/08/2008. Primeiramente efetuou-se uma análise do comportamento gráfico dos preços dos ativos das BDRs listadas. Posteriormente elaborou-se três regressões múltiplas utilizando-se um modelo de série temporal (modelo AR – auto-regressivo), com análise de quebra estrutural e uso de variável Dummy. A primeira regressão relaciona a variável Agrenco com índices de BDRs constituídos especificamente para este estudo, a segunda inclui uma variável Dummy de intercepto e a terceira combina a variável Dummy de intercepto com uma variável Dummy de inclinação. As regressões têm o objetivo de se averiguar se o evento da Agrenco afetou sistematicamente os preços das ações listadas sob a mesma forma. A maior contribuição do estudo foi verificar que a má prática de gestão na Agrenco, listada sob a forma de BDR, contaminou o retorno de outras empresas que se utilizaram do mesmo veículo como fonte de captação de recursos. Os resultados apontaram, pela análise gráfica, que não houve um descolamento da valorização da maior parte das ações uma semana depois do anúncio dos problemas financeiros da Agrenco em relação a carteira téorica de mercado (IBOVESPA). Entretanto, os resultados dos testes econométricos apontaram que houve impacto do evento Agrenco sobre os retornos das ações listadas sob a forma de BDR.

Impacto de uma melhor governança corporativa e uma maior escolaridade do conselho de administração e da diretoria executiva no d-beta das empresas

O desenvolvimento do mercado financeiro e, principalmente, a abertura para o capital externo impulsionaram o desenvolvimento das boas práticas de governança corporativa. Um de seus benefícios é reduzir o custo de captação da empresa e, consequentemente, gerar maior valor para a companhia. Com o novo cenário, o conselho de administração tem um papel fundamental na atividade de governança corporativa, supervisionando a diretoria executiva. O presente trabalho investiga se a adoção de melhores práticas de governança corporativa diminui o risco das empresas. Adicionalmente, analisa se um grau de escolaridade mais alto entre membros do conselho de administração e da diretoria executiva impacta no risco. Para atingir o objetivo, adotou-se o método dos mínimos quadrados para regredir o risco, variável dependente, contra as variáveis independentes nível de governança corporativa e grau de escolaridade. Para o cálculo do risco, utilizaremos a metodologia apresentada por Estrada (2007), o downside beta, ou seja, risco que considera apenas os retornos negativos. Os resultados do estudo sugeriram que um nível de governança corporativa mais alto está presente nas empresas que apresentam um maior risco visto pelo mercado, indicando que as empresas que necessitam de captação, isto é, empresas mais alavancadas, são as empresas que necessitam de um nível de governança corporativa mais alto. Constatou-se, também, que empresas com nível de escolaridade mais alto entre membros do conselho de administração e da diretoria executiva apresentam maiores riscos, pois as empresas que necessitam de pessoas com maior grau de escolaridade são empresas que querem se desenvolver e, portanto, mais arriscadas.
