Bubble detection in Brazil’s stock market: application of the generalized superior augmented Dickey-Fuller test

Considering the importance of the proper detection of bubbles in financial markets for policymakers and market agents, we used two techniques described in Diba and Grossman (1988b) and in Phillips, Shi, and Yu (2015) to detect periods of exuberance in the recent history of the Brazillian stock market. First, a simple cointegration test is applied. Secondly, we conducted several augmented, right-tailed Dickey-Fuller tests on rolling windows of data to determine the point in which there’s a structural break and the series loses its stationarity.

Partial economic reforrns and financial crises: an emerging markets perspective

The recent emerging market experiences have posed a challenge to the conventional wisdom that unsustainable fiscal deficits are the key to understanding financial crises in these countries. The health of the domestic banking system has emerged as the main driving force behind the perverse dynamics of partial reforms. The current paper shares this view and uses a model of contractual inefliciencies in the banking sector to understand the dynamics of these reforms. We find that the threat of a large exchange rate devaluation depends on the stock of international reserves relative to the stock of domestic credit that must be extended by the Central Bank in response to a large capital outflow. Moreover, if a country has a weak banking sector but high net reserve ratios, the capital flow reversal might only increase the vulnerability to a currency crisis without necessarily causing it. The results are in accordance with much of the empiricalliterature on the determinants of financiaI crises in emerging markets. Some aspectsof the recent policy debate on the introduction of capital controls are also analysed.

The global financial crisis and after: a new capitalism?

The 2008 global financial crisis was the consequence of the process of financialization, or the creation of massive fictitious financial wealth, that began in the 1980s, and of the hegemony of a reactionary ideology, namely, neoliberalism, based on selfregulated and efficient markets. Although capitalism is intrinsically unstable, the lessons from the stock-market crash of 1929 and the Great Depression of the 1930s were transformed into theories and institutions or regulations that led to the “30 glorious years of capitalism” (1948–77) and that could have avoided a financial crisis as profound as the present one. It did not because a coalition of rentiers and “financists” achieved hegemony and, while deregulating the existing financial operations, refused to regulate the financial innovations that made these markets even more risky. Neoclassical economics played the role of a meta-ideology as it legitimized, mathematically and “scientifically”, neoliberal ideology and deregulation. From this crisis a new capitalism will emerge, though its character is difficult to predict. It will not be financialized but the tendencies present in the 30 glorious years toward global and knowledge-based capitalism, where professionals will have more say than rentier capitalists, as well as the tendency to improve democracy by making it more social and participative, will be resumed.

The value of local partners in Brazil: the effects of ownership clusters and business group membership on firm value in emerging markets

Este estudo analisa como a classe de acionistas afeta o valor das empresas brasileiras listadas na bolsa de valores no ponto de vista da governança corporativa. O trabalho examina a interação entre o valor das empresas e cinco tipos de concentrações acionárias comumente presente em mercados emergentes: famílias, agentes públicos, investidores estrangeiros, executivos e investidores financeiros nacionais. A análise empírica demonstra que o mix e a concentração de participação acionária afeta significativamente o valor das empresas. Utilizando uma compilação única de dados em painel de 2004 a 2008, a presente pesquisa também desenvolve hipóteses sobre o efeito da participação em grupos econômicos para o valor das empresas. A investigação encontra evidências de que, apesar de sua importância para o desenvolvimento de empresas brasileiras, o capital familiar, instituições públicas, e investidores estrangeiros estão cedendo lugar a monitores mais especializados e menos concentrados, como executivos e instituições financeiras nacionais. Estes resultados indicam que a governança corporativa no Brasil pode estar alcançando níveis de maturidade mais elevados. Adicionalmente, apesar de não haver indicação da existência de correlação entre a participação em grupos econômicos e o valor das empresas, os resultados indicam que a presença de um tipo específico de acionista em uma empresa do grupo facilita investimentos futuros desta classe de acionista em outras empresas do mesmo grupo, sinalizando que os interesses acionários são provavelmente perpetuados dentro de uma mesma rede de empresas. Finalmente, a pesquisa demonstra que enquanto o capital familiar prefere investir em empresas com ativa mobilidade do capital, investidores internacionais e instituições públicas procuram investimentos em equity com menor mobilidade de capital, o que lhes garante mais transparência com relação ao uso dos recursos e fundos das empresas.

Assets, markets and poverty in Brazil

Esse artigo estabelece uma base para pesquisas que tratam da relação entre pobreza, distribuição de recursos e operação do mercado de capitais no Brasil. O principal objetivo é auxiliar a implementação de políticas de reforço de capital dos pobres. A disponibilidade de novas fontes de dados abriu condições inéditas para implementar uma análise de posse de ativos e pobreza nas áreas metropolitanas brasileiras. A avaliação de distribuição de recursos foi estruturada sobre três itens: Capital físico, capital humano e capital social. A estratégia empírica seguida é de analisar três diferentes tipos de impactos que o aumento dos ativos dos pobres podem exercer no nível de bem estar social. A primeira parte do artigo avalia a posse de diferentes tipos de capitais através da distribuição de renda. Esse exercício pode ser encarado como uma ampliação de medidas de pobreza baseadas em renda pela incorporação de efeitos diretos exercidos pela posse de ativos no bem estar social. A segunda parte do artigo descreve o impacto de geração de renda que a posse de ativos pode ter sobre os pobres. Estudamos como a acumulação de diferentes tipos de capital impactam os índices de pobreza baseados na renda usando regressões logísticas. A terceira parte estuda o efeito que o aumento da posse de ativos dos pobres tem no melhoramento da habilidade dos indivíduos pobres em lidar com choques adversos da renda. Estudamos a interação entre a dinâmica da renda, imperfeições do mercado de capitais e comportamentos financeiros levando em consideração diferentes horizontes de tempo. As questões de longo prazo estão relacionadas com o estudo das flutuações de renda de baixa freqüência e ciclo da vida da posse de ativos usando análise de coorte. As questões de curto prazo estão relacionadas com o comportamento do pobre e as perdas de bem estar ao lidar com hiatos de alta freqüência entre renda e consumo desejado. A análise da dinâmica de renda e pobreza é conduzida a partir da combinação de dados de painel de renda com dados qualitativos sobre comportamento financeiro de curto prazo das famílias.

The relationship between board of director's nationality diversity and financial performance

Companies are moving to a more international structure; going into new markets and having an increased competition in all fronts. Therefore, the practices that lead companies to a more efficient and competitive position are praised. The management of the workforce comes as one of the main concerns of companies, aiming at performance enhancing and at creating better environments that both attract and maintain the professional talents. In an increasingly international environment, companies tend to look for the specialists and best professionals, regardless of their nationality. This new structure with several different nationalities working together poses new challenges for companies. Understanding if and how a more diverse has a relationship with financial performance is the starting point for better managing this new corporate structure.

Do capital controls boost EME´s resilience to financial crises?

Capital controls are again in vogue as a number of emerging markets have reintroduced these measures in recent years in response to a “flood” of international capital. Policymakers use these tools to buttress their economies against the “sudden stop” risk that accompanies international capital flows. Using a panel VAR model, we show that capital controls appear to make emerging market economies (EMEs) more resistant to financial crises by showing that lower post-crisis output loss is correlated with stronger capital controls. However, EMEs that employ capital controls seem to be more crisis-prone. Thus, policymakers should carefully evaluate whether the benefits of capital controls outweigh their costs.

Financial frictions, informality and income inequality

We studied the effects of changes in banking spreads on distributions of income, wealth and consumption as well as the welfare of the economy. This analysis was based on a model of heterogeneous agents with incomplete markets and occupational choice, in which the informality of firms and workers is a relevant transmission channel. The main finding is that reductions in spreads for firms increase the proportion of entrepreneurs and formal workers in the economy, thereby decreasing the size of the informal sector. The effects on inequality, however, are ambiguous and depend on wage dynamics and government transfers. Reductions in spreads for individuals lead to a reduction in inequality indicators at the expense of consumption and aggregate welfare. By calibrating the model to Brazil for the 2003-2012 period, it is possible to find results in line with the recent drop in informality and the wage gap between formal and informal workers

Equilibria in exchange economies with financial constraints : beyond the Cass trick

We consider an exchange economy under incomplete financiaI markets with purely financiaI securities and finitely many agents. When portfolios are not constrained, Cass [4], Duffie [7] and Florenzano-Gourdel [12] proved that arbitrage-free security prices fully characterize equilibrium security prices. This result is based on a trick initiated by Cass [4] in which one unconstrained agent behaves as if he were in complete markets. This approach is unsatisfactory since it is asymmetric and no more valid when every agent is subject to frictions. We propose a new and symmetric approach to prove that arbitrage-free security prices still fully characterize equilibrium security prices in the more realistic situation where the financiaI market is constrained by convex restrictions, provided that financiaI markets are collectively frictionless.

Firm financial constraints and the impact of monetary policy: evidence from financial conglomerates

Building on recent evidence on the functioning of internal capital markets in financial conglomerates, this paper conducts a novel test of the balance sheet channel of monetary policy. It does so by comparing monetary policy responses of small banks that are affiliated with the same bank holding company, and this arguably face similar constraints in accessing internal/external sources of funds, but that operate in different geographical regions, and thus face different pools of borrowers. Because these subsidiaries typically concentrate their lending with small local businesses, we can use cross-sectional differences in state-level economic indicators at the time of changes of monetary policy to study whether or not the strength of borrowers' balance sheets influences the response of bank lending. We find evidence that the negative response of bank loan growth to a monetary contraction is significantly stronger when borrowers have 'weak balance sheets. Our evidence suggests that the monetary authority should consider the amplification effects that financial constraints play following changes in basic interest rates and the role of financial conglomerates in the transmission of monetary policy.

The influence of the global crisis on the slowdown of the emerging markets

A presente dissertação investiga a relação empírica entre a crise financeira de 2007-2009, a crise da dívida soberana de 2010-2012 e a recente desaceleração dos mercados de capitais nos mercados emergentes. A exposição dos mercados emergentes à crise nos desenvolvidos é quantificada através de um modelo de interdependência de factores. Os resultados mostram que estes sofreram, de facto, um choque provocado por ambas as crises. No entanto, este foi um choque de curta duração enquanto os mercados desenvolvidos ainda lutavam com as consequências resultantes das sucessivas crises financeiras. A análise do modelo mostra ainda que após a crise da divida soberana, enquanto os mercados desenvolvidos iniciam a sua recuperação, os emergentes desaceleram o seu crescimento. De forma a completar a análise do modelo foi efectuado um estudo sobre a influência dos fluxos de capitais entre os mercados emergentes e desenvolvidos na direcção do seu crescimento, revelando que existe uma relação entre estes dois eventos.

The development of the private equity industry since the 2008 financial crisis

The private equity industry was experiencing a phenomenal boom at the turn of the century but collapsed abruptly in 2008 with the onset of the financial crisis. Considered one of the worst crises since the Great Depression of the 1930s, it had sent ripples around the world threatening the collapse of financial institutions and provoking a liquidity crunch followed by a huge downturn in economic activity and recession. Furthermore, the physiognomy of the financial landscape had considerably altered with banks retracting from the lending space, accompanied by a hardening of financial regulation that sought to better contain systemic risk. Given the new set of changes and challenges that had arisen from this period of financial turmoil, private equity found itself having to question current practices and methods of operation in order to adjust to the harsh realities of a new post-apocalyptic world. Consequently, this paper goes on to explore how the private equity business, management and operation model has evolved since the credit crunch with a specific focus on mature markets such as the United States and Europe. More specifically, this paper will aim to gather insights on the development of the industry since the crisis in Western Europe through a case study approach using as a base interviews with professionals working in the industry and those external to the sector but who have/have had considerable interaction with PE players from 2007 to the present.

Beyond ‘best practices': the international regulation of capital markets

It is widely acknowledged that there is considerable international pressure for international ‘best practices’ to be adopted via national legislation. This would occur either by means of model laws or through the passing of country specific legislation that closely replicates foreign legal formats, administrative rules, and or regulation. These attempts to spread the implementation of ‘best practices’ have gained importance in the international debate due to the liberalization of international capital flows. The oversight, country reports, and technical assistance carried out by international organizations along with the growing internationalization of investors have also contributed to this growing pressure. In this respect, due to the constant evolution of transactions and the end objective of making sure that capital markets are developed with just rules, structures, and methods, this article looks to analyze the adoption of standardized models of capital market regulation. Furthermore it looks to examine the motivation and interest of states and other ‘stakeholders’ at the international level.

An essay on impression management: three randomized experiments with financial analysts

This thesis aims to explore the concept of impression management from the financial analysts’ point of view. Impression management is the definition of the act of an agent manipulating an impression that another person have of this agent, in the context of this thesis it happens when a company make graphics to disclosure financial-accounting information in order to manipulate the market’s perception of their performance. Three types of impression management were analyzed: presentation enhancement (color manipulation), measurement distortion (scale manipulation) and selectivity (the disclosure of positive information only). While presentation enhancement improved only the most impulsive financial analysts’ perception of firm’s performance, the measurement distortion improved the perception of performance for both groups of financial analysts (impulsive and reflective). Finally, selectivity improved the financial analysts’ perception of firm’s performance for both groups (impulsive and reflective), although impulsive financial analysts assigned lower ratings when compared to their reflective peers, on average, to a hypothetical company.

Valuing emerging markets companies : new approaches to determine the effective exposure to country risk

The aim of this paper is to propose new methods to measure the effective exposure to country risk of emerging-market companies. Starting from Damodaran (2003), we propose seven new approaches and a revised CAPM for emerging markets companies. The “Prospective Lambda” represents the effective exposure according to analysts’ estimates of growth. The “Relative Lambda” relies on the firm value estimated through a relative valuation. The “Retrospective Lambda” represents the ex-post effective exposure to country risk. The “Company Effective Risk Premium” is a generalization of the Retrospective Lambda, and expresses the premium effectively requested by investors to invest in that specific company in the past year. “The Actual Lambda” and the “Company Actual Risk Premium” represent, respectively, the actual exposure to country risk of a company and the actual premium requested by investors to invest in that specific company. The “Industry Lambda” reflects the median exposure to country risk of the industry in which the company belongs. We tested our new measures of exposure to country risk on the Latin American emerging markets companies according to the classification of the MSCI Emerging Markets Latin America Index. The results confirm that the new approaches can be effectively applied by financial analysts to stable-growth companies that operate in emerging markets and to mature markets companies that operate in emerging markets, providing with a more reliable estimate of both the premium effectively requested by investors in the past and the actual premium. Applying the new approaches, the cost of equity reflects the effective exposure of a company to country risk without being over- or underestimated, as is the case with other existing approaches.
