Performance contrasts during the financial crisis between publicly traded family and non-family firms in Europe

Neste estudo, analiso o desempenho de empresas familiares e não-familiares na Europa, entre 2001 e 2013, com uma especial atenção ao período da crise financeira de 2008 e 2009. Doze anos de dados foram recolhidos e analisadosusando dois modelos: o modelo de ajustamento do mercado e uma técnica de estimativa de painéis. Ao contrário das expectativas, os resultados mostram que as empresas familiares não têm resultados significativamente superiores às empresas não familiares durante o período em análise, inclusive antes, durante, e depois da crise. No entanto, considerando o valor do beta, existem diferenças significativas. É possível concluir que as empresas familiares são, em geral, menos voláteis e que durante a crise apresentaram uma volatilidade extremamente baixa comparativamente com o mercado.JEL

Insider trading, investment, and liquidity: a welfare analysis

We compare competitive equilibrium outcomes with and without trading by a privately infonned "monopolistic" insider, in a model with real investment portfolio choices ex ante, and noise trading generated by aggregate uncertainty regarding other agents' intertemporal consumption preferences. The welfare implications of insider trading for the ex ante expected utilities of outsiders are analyzed. The role of interim infonnation revelation due to insider trading, in improving the risk-sharing among outsiders with stochastic liquidity needs, is examined in detaiL

The effect of financiaI repression & enforcernent on entrepreneurship and economic deveIopment

This paper studies the effect of financiaI repression and contract enforcement on entrepreneurship and economic development. We construct and solve a general equilibrium mo deI with heterogeneous agents, occupational choice and two financiaI frictions: intermediation costs and financiaI contract enforcement. Occupational choice and firm size are determined endogenously, and depend on agent type (wealth and ability) and the credit market frictions. The mo deI shows that differences across countries in intermediation costs and enforcement generate differences in occupational choice, firm size, credit, output and inequality. Counterfactual experiments are performed for Latin American, European, transition and high growth Asian countries. We use empirical estimates of each country's financiaI frictions, and United States values for all other parameters. The results allow us to isolate the quantitative effect of these financiaI frictions in explaining the performance gap between each country and the United States. The results depend critically on whether à general equilibrium factor price effect is operative, which in turn depends on whether financiaI markets are open or closed. This yields a positive policy prescription: If the goal is to maximize steady-state efficiency, financial reforms should be accompanied by measures to increase financiaI capital mobility.

Simulation-based smoothing and filtering in factor stochastic volatility models : two econometric applications

In this article we use factor models to describe a certain class of covariance structure for financiaI time series models. More specifical1y, we concentrate on situations where the factor variances are modeled by a multivariate stochastic volatility structure. We build on previous work by allowing the factor loadings, in the factor mo deI structure, to have a time-varying structure and to capture changes in asset weights over time motivated by applications with multi pIe time series of daily exchange rates. We explore and discuss potential extensions to the models exposed here in the prediction area. This discussion leads to open issues on real time implementation and natural model comparisons.

Simulation -based smoothing and filtering in factor stochastic volatility models : two econometric applications (July-2001)

The past decade has wítenessed a series of (well accepted and defined) financial crises periods in the world economy. Most of these events aI,"e country specific and eventually spreaded out across neighbor countries, with the concept of vicinity extrapolating the geographic maps and entering the contagion maps. Unfortunately, what contagion represents and how to measure it are still unanswered questions. In this article we measure the transmission of shocks by cross-market correlation\ coefficients following Forbes and Rigobon's (2000) notion of shift-contagion,. Our main contribution relies upon the use of traditional factor model techniques combined with stochastic volatility mo deIs to study the dependence among Latin American stock price indexes and the North American indexo More specifically, we concentrate on situations where the factor variances are modeled by a multivariate stochastic volatility structure. From a theoretical perspective, we improve currently available methodology by allowing the factor loadings, in the factor model structure, to have a time-varying structure and to capture changes in the series' weights over time. By doing this, we believe that changes and interventions experienced by those five countries are well accommodated by our models which learns and adapts reasonably fast to those economic and idiosyncratic shocks. We empirically show that the time varying covariance structure can be modeled by one or two common factors and that some sort of contagion is present in most of the series' covariances during periods of economical instability, or crisis. Open issues on real time implementation and natural model comparisons are thoroughly discussed.

Modelos de volatilidade estocástica com deformação temporal : com aplicação aos dados do IBOVESPA

Estimar e prever a volatilidade de um ativo é uma tarefa muito importante em mercados financeiros. Nosso objetivo neste trabalho é propor o conceito de deformação temporal neste contexto. A idéia é que o mercado modifica-se com a chegada de novas informações, e não com o decorrer do tempo de calendário. Nós estimamos a volatilidade dos retornos do IBOVESPA, aplicando Modelos de Volatilidade Estocástica sem e com Deformação Temporal.

Extreme observations and diversification in Latin American emerging equity markets

In this paper, we focus on the tails of the unconditional distribution of Latin American emerging markets stock returns. We explore their implications for portfolio diversification according to the safety tirst principIe, tirst proposed by Roy (1952). We tind that the Latin American emerging markets have signiticantly fatter tails than industrial markets. especially, the lower tail of the distrihution. We consider the implication of the safety tirst principIe for a U .S. investor who creates a diversitied portfolio using Latin American stock markets. We tind that a U.S. investor gains by adding Latin American equity markets to her purely domestic portfolio. For different parameter specitications. we finu a more realistic asset allocation than the one suggested by the Iiterature haseu on the traditional mean-variance framework.

Informational spillovers in the pre-1914 London sovereign debt market

We document a novel type of international financial contagion whose driving force is shared financial intermediation. In the London peripheral sovereign debt market during pre-1914 period financial intermediation played a major informational role to investors, most likely because of the absence of international monitoring agencies and the substantial agency costs. Using two events of financial distress – the Brazilian Funding Loan of 1898 and the Greek Funding Loan of 1893 – as quasi-natural experiments, we document that, following the crises, the bond prices of countries with no meaningful economic links to the distressed countries, but shared the same financial intermediary, suffered a reduction relative to the rest of the market. This result is true for the mean, median and the whole distribution of bond prices, and robust to an extensive sensitivity analysis. We interpret it as evidence that the identity of the financial intermediary was informative, i.e, investors extracted information about the soundness of a debtor based on the existence of financial relationships. This spillover, informational in essence, arises as the flip-side of the relational lending coin: contagion arises for the same reason why relational finance, in this case, underwriting, helps alleviate informational and incentive problems.

Ensaios sobre estrutura a termo da curva de juros e spreads de títulos corporativos

Este trabalho é composto por três capítulos que se dedicam a discutir aspectos distintos a respeito do importante mercado de títulos corporativos norte-americano. No primeiro capítulo, “Mercado de Títulos Corporativos Norte-Americano: Evolução e Fatos Estilizados”, mostramos como se deu a evolução do mercado de crédito norte-americano nas últimas décadas no que diz respeito à sua relevância para a economia. Nesse estudo mostramos também as principais mudanças regulatórias que afetaram de forma relevante esse mercado nos últimos anos. Trabalhos recentes encontraram evidências de que mudanças regulatórias no mercado de títulos corporativos provocam redução dos spreads e diminuem a liquidez dos ativos de crédito. Finalmente, ilustramos nesse capítulo as principais correntes teóricas e alguns fatos estilizados a respeito de curvas de juros e de spreads de títulos corporativos. No segundo capítulo, “Fatores Latentes Globais e Idiossincráticos na Estrutura a Termo da Curva de Juros de Títulos Corporativos”, analisamos a maneira como fatores globais e idiossincráticos influenciam a estrutura a termo das curvas de juros de emissores corporativos norte-americanos para diferentes níveis de classificação de risco, setor de atividade e período de análise. Os resultados são inéditos, pois a metodologia utilizada nunca foi aplicada anteriormente para essa classe de ativos, e indicam que a influência dos componentes latentes globais nos fatores de nível é menor quanto pior a classificação de risco. Um segundo resultado importante é que as curvas de setores de atividade distintos como o financeiro e industrial são influenciadas de maneira distinta pelos fatores globais e idiossincráticos no que diz respeito aos componentes de nível e inclinação. No terceiro capítulo, “Estrutura a Termo da Curva de Spreads de Títulos Corporativos”, estudamos as variáveis que influenciaram os fatores de nível e inclinação das curvas de spreads corporativos nos Estados Unidos. O modelo estimado nesse estudo incorpora, ao contrário de estudos anteriores, fatores latentes das curvas de juros do tesouro e de spreads, variáveis macroeconômicas e setoriais. Concluímos que o componente de nível da curva de juros norte-americana afeta positivamente o nível dos spreads. Os resultados diferem da literatura tradicional, mas estão em linha com estudos recentes que controlam períodos de elevada volatilidade de ativos com quebras estruturais. Palavras-chave: Spreads; Classificação de risco; Curva de juros; Títulos corporativos

Do equity and foreign currency risk premiums display common patterns?

In da Costa et al. (2006) we have shown how a same pricing kernel can account for the excess returns of the S&:P500 over the US short term bond and of the uncovered over the covered trading of foreign government bonds. In this paper we estimate and test the overidentifying restrictiom; of Euler equations associated with "ix different versions of the Consumption Capital Asset Pricing I\Iodel. Our main finding is that the same (however often unreasonable) values for the parameters are estimated for ali models in both nmrkets. In most cases, the rejections or otherwise of overidentifying restrictions occurs for the two markets, suggesting that success and failure stories for the equity premium repeat themselves in foreign exchange markets. Our results corroborate the findings in da Costa et al. (2006) that indicate a strong similarity between the behavior of excess returns in the two markets when modeled as risk premiums, providing empirical grounds to believe that the proposed preference-based solutions to puzzles in domestic financiaI markets can certainly shed light on the Forward Premium Puzzle.

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.

Why designate market makers? affirmative obligations and market quality

We study why most financiaI markets designate one or more agents who precommit to provide more liquidity than they would endogenously choose, and identify two reasons that such affirmative obligations can improve welfare. The first relies on the insight that the informational component of the competi tive bid-ask spread represents a transfer across traders, not a social cost to completing trades. As such, this trading cost dissuades efficient trading, while a restriction on spread widths encourages efficient trading. Secondly, a restriction on spread widths encourages traders to become informed, which speeds the rate at which market prices move toward true asset values in the wake of information events. We consider the setting where competition ensures that affirmative obligations impose net trading losses on designated market makers that must be compensated by side payments, as observed on the Euronext limit order market, and also the setting where the designated market maker is allowed some advantages relative to limit order traders so that profits can be eamed during tranquil periods to offset losses incurred when affirmative obligations are binding, as observed on the NYSE.
