AnÃlise das decisÃes do CADE com uso de estudos de eventos / CADE's decisions of the analysis using event studies

Pedro Rafael Lopes Fernandes 29 May 2014 (has links)
nÃo hà / The purpose of this research is evaluate CADEâs decisions about the mergers Santander à Real (2007), Itaà à Unibanco (2008), Gol à Webjet (2011) e Trip à Azul (2012), using the event study methodology. This methodology proposed by Eckbo (1983) lies on market efficiencyâs hypothesis which says the market value of a firm reflects the present value of its expected cash flow. Hereupon, Eckbo (1983) argues that anticompetitive mergers are good also for rivals of the merging firms. Since the price increases of merging firms also enables rivals to increase their own price. So, if the market assess the merger as anticompetitive, the rival firmâs stocks will increase with the announcement of this transaction. The results demonstrate a high level of efficiency of CADEâs decisions. / O objetivo deste trabalho à avaliar decisÃes tomadas pelo CADE relacionadas Ãs fusÃes Santander à Real (2007), Itaà à Unibanco (2008), Gol à Webjet (2011) e Trip à Azul (2012) utilizando a metodologia de estudos de eventos. Esta metodologia proposta por Eckbo (1983) reside na hipÃtese de eficiÃncia do mercado de aÃÃes que nos diz que o valor de mercado de uma firma reflete o valor presente de seu fluxo de caixa esperado. Dito isto, Eckbo (1983) argumenta que fusÃes anticompetitivas sÃo boas nÃo apenas para as merging firms, mas tambÃm para suas rivais, pois, uma elevaÃÃo nos preÃos da nova firma permite que as rivais elevem tambÃm o preÃo de seus produtos. Se o mercado financeiro à eficiente e avalia que uma determinada fusÃo serà anticompetitiva, à sinalizado como resposta ao anÃncio desta fusÃo uma elevaÃÃo no valor das das aÃÃes das empresas rivais. A metodologia de estudos de eventos demonstrou que o CADE vem atingindo um elevado nÃvel de eficiÃncia em suas decisÃes.

Via applying event study methodology, the research on the Ibovespa and Petrobras suggests that events in which Rousseff was gaining in share have been subject to negative abnormal returns, and events where Rousseff was loosing in share have led to positive abnormal returns. Moreover, volatility has been significantly elevated during the election period and volume has been found to have slightly increased. / Este estudo investiga se houve comportamento anormal no mercado de ações no Brasil decorrente de notícias sobre as últimas eleições presidenciais brasileiras (através da utilização de sondagens), realizadas em outubro de 2014. Utilizando uma metodologia de estudos de evento (event studies), a investigação sobre o Ibovespa e a Petrobras sugere que, nos períodos em que Dilma melhorava a sua posição nas sondagens existiram retornos anormais negativos e, nos períodos em que Rousseff piorava a sua posição, existiram retornos anormais positivos. Além disso, a volatilidade foi bastante elevada durante o período eleitoral tendo o volume de transações aumentado ligeiramente.
