Merger &Acquisition is a way to allocate resources in the capital market, and also a way for enterprises to expand scale. Since the real estate industry has a prominent position in the national economy, and M&A events in the real estate industry are also increasing year by year, it is worth studying whether M&A can improve the performance of M&A enterprises. From the perspective of horizontal M&A of real estate enterprises, this paper studies whether the short-term and long-term performance of listed real estate enterprises can be improved under horizontal M&A. First, this paper studies the background of M&A, the performance of M&A and the motivation of M&A relate to the theory and analyzes development of the real estate industry in recent years. After that, this paper begins to conduct an empirical study on the short-term performance and the long-term performance of horizontal M&A of listed real estate enterprises. This paper selects the horizontal M&A of real estate enterprises occurred in 2016 as the research samples. The short-term research calculates the CAR of each day of the event window by using the method of event studying, and compares its change. The long-term research uses the method of factors studying to calculate the comprehensive performance score of each year before and after M&A. The research result of this paper shows that although horizontal M&A of real estate companies brings positive cumulative abnormal return in the short term, the CAR is very small. In the long term, the comprehensive performance scores of horizontal M&A of real estate companies decline and then rise slowly before and after M&A. Besides, in this paper, starting from the features of the real estate industry, I analysis the driving factors of M&A of the real estate and build the M &A performance evaluation system of real estate enterprises. Using the case method, with the help of the M&A performance evaluation system, this paper analyzed the performance of Chinese real estate enterprises-Vanke after M&A from short-term and long-term performance, finding out the factors to drive the improvement of performance of vanke through M&A. According to the analysis of the case, a series of suggestions are proposed from internal and external to improve performance of real estate enterprise after M&A of our country.Finally, this paper puts forward some suggestions to the participants of M&A. For example, listed real estate enterprises should pay attention to the cost of M&A and resource integration; Government departments should pay attention to marketization; Intermediary agent should be diligent and responsible. / Business Administration/Finance

This crisis affected the Brazilian Financial System, contributing to the adoption of several prudential measures to soften their effects. As a consequence of such crisis, the European fiscal crisis started in mid-2010, with new expansive measures being adopted in Brazil in 2011. This study evaluated how these international financial crises and prudential measures adopted by the Brazilian Central Bank affected the stock and the financial performance of Brazilian Banks. It was used the methodology of event study and of financial analysis based on the evaluation of accounting indexes, which are traditional in the banking system (CAMELS). It was noticed that the stock performance of the banks, in general, was not statistically affected by the selected events. This behavior can be partially explained by the dynamic nature of the events, which only happen after consecutive disclosure of relevant information about the economic environment and the companies to the market. Regarding the financial performance, it was noticed that, in moments of crises, the banks adopt a more conservative posture towards credit concession, due to higher delinquencies and lower profitability. Banks focus on improving their liquidity conditions. Despite overall negative impact of financial crises over the banks profitability and asset quality of Brazilian Banks, the strong capital structure of the banking system allowed the absorption of such losses / A falência do Lehman Brothers em 2008 rapidamente desencadeou um severo risco sistêmico no mercado bancário global e resultou na pior crise financeira desde a Grande Depressão em 1929. Esta crise afetou o sistema financeiro brasileiro, provocando a adoção de diversas medidas prudenciais para combater seus efeitos. Como desdobramento desta crise, surgiu a crise fiscal européia em meados de 2010 com novas medidas expansionistas sendo adotadas no Brasil em 2011. O presente trabalho avaliou como estas crises financeiras internacionais e as medidas prudenciais adotadas pelo Banco Central do Brasil afetaram o desempenho bursátil e contábil dos bancos brasileiros. Para isso, foram utilizados os métodos de estudo de eventos e a análise financeira baseada na leitura de índices contábeis tradicionais do segmento bancário (CAMELS). Percebeu-se que o desempenho bursátil dos bancos, de modo geral, não foi afetado de forma estatisticamente significativa pelos eventos sistêmicos selecionados. Em parte, tal comportamento pode ser explicado pela natureza dinâmica dos eventos, os quais somente são deflagrados após a divulgação sequencial de informações relevantes da conjuntura econômica e de empresas ao mercado. Quanto ao desempenho financeiro , constatou-se que em momentos de crise, os bancos adotaram uma postura mais cautelosa na concessão de crédito, resultante de aumento de inadimplência e queda de rentabilidade, concentrando esforços na construção de liquidez. Mesmo com os impactos negativos das crises financeiras sobre a rentabilidade e qualidade de ativos do bancos brasileiros estudados nesta pesquisa, a forte estrutura de capital do sistema bancário, permitiu a absorção de tais perdas

This demand has been strengthening over time and today is extensively attended by many financial instruments in the local and international market. In this context, this study analyzed the inclusion of companies, from 2011 to 2013, to socially responsible company s portfolio (Corporate Sustainability Index), evaluated a set of indicators of stock prices before and after the inclusion in the ISE, compared stock markets performance before and after the announcement of the inclusion. The objective, through the events study, was to evaluate if the investor had value aggregated to its equity by decision of the company s managers to enter the ISE. Inside this context, it also evaluated if the market announcement that they are socially correct companies was able to imply this perception and if stockholders had above average return because of this event. The results observed in this paper (in average) show indication that the market positively evaluates the sustainability efforts and is willing to repay for that. However, this reality doesn t hold for long. For 2013, a new fact that hadn t occurred before can be observed: the indication of a turnaround in the markets perception regarding sustainability efforts by companies. This year, the abnormal returns (WEG companies) continued after the announcement of entering the index. This fact can indicate that the announcement could have been able to increase the stockholder wealth / Segundo responsáveis pelo ISE (Índice de Sustentabilidade Empresarial), as aplicações denominadas investimentos socialmente responsáveis, consideram que empresas sustentáveis geram valor para o acionista no longo prazo, pois estão mais preparadas para enfrentar riscos econômicos, sociais e ambientais. Essa demanda veio se fortalecendo ao longo do tempo e hoje é amplamente atendida por vários instrumentos financeiros no mercado nacional e internacional. Nesse contexto, este trabalho analisou a entrada das empresas, de 2011 a 2013, na carteira de empresas responsáveis socialmente (Índice de Sustentabilidade Empresarial). Avaliou o conjunto de indicativos de preço das ações antes e depois de entrada no ISE. Comparou o desempenho do mercado de ações diretamente com período anterior e um posterior ao anúncio de entrada nesse índice. O objetivo, através do estudo de eventos, foi avaliar se o investidor agregou valor ou não ao seu patrimônio por decisão dos gestores das companhias quando da entrada no índice de sustentabilidade. Dentro desse contexto, avaliou também se o fato de comunicar ao mercado que são empresas socialmente corretas foi capaz de fazer valer essa percepção e se os acionistas dessas empresas tiverem retorno acima do normal por esse evento. Os resultados observados neste trabalho (na média) trazem indícios de que o mercado avalia positivamente os esforços de sustentabilidade e está disposto a remunerar melhor por isso, porém esse patamar não se mantém no tempo. Já para o ano de 2013 observa-se um fato novo, não ocorrido até o momento, que são indícios de uma virada na percepção do mercado quanto aos esforços de sustentabilidade das empresas. Nesse ano, os retornos anormais (para empresa WEG) continuaram após o momento do anúncio da entrada no índice. Esse fato pode indicar que o fato público teria sido capaz de maximizar a riqueza do acionista

La thèse analyse les effets de la régulation sur le risque systématique d’un panel de 17 grands opérateurs de télécommunications européens entre 1997 et 2012. La relation régulation/risque est étudiée sous trois angles : (i) via la modification de la distribution des revenus de la firme, (ii) la promotion de l’intensité concurrentielle, et (iii) les choix de structure financière des opérateurs. Une modélisation de l’impact de la régulation sur la structure financière de la firme met en évidence que la hausse stratégique de l’endettement peut accroitre ou décroitre le risque systématique. Trois méthodologies d’estimations du risque sont utilisées : les MCO et le filtre de Kalman sans et avec effet TGARCH. Les trois aspects de la relation risque/régulation sont ensuite abordés via une étude en données de panel (couvrant les ratios financiers, l’intensité concurrentielle, l’intensité et le régime de régulation) puis en évaluant la réaction du risque aux annonces d’évolutions du cadre réglementaire européen (étude d’évènements). / The thesis analyzes the effects of regulation on the systematic risk of a panel of 17 leading European telecommunications operators between 1997 and 2012. The regulation / risk relationship is studied through: (i) the changes in the firm income distribution, (ii) the promotion of competitive intensity, and (iii) the operators' choice of financial structure. Modeling the impact of regulation on the financial structure of the firm highlights that strategic increase in debt may increase or decrease the systematic risk. Three estimation methodologies of risk are used: OLS and Kalman filter technics with and without TGARCH effect. The three aspects of risk / regulation relationship are then addressed through a panel data study (covering financial ratios, competitive intensity, and regulatory regime index) and then by an events study evaluating market reactions to announcements of changes in the European regulatory framework.
