No. of bitstreams: 1 Carla_Caricatti_Guimaraes.pdf: 776617 bytes, checksum: 274057dc13fa582f540363f534589442 (MD5) Previous issue date: 2010-09-10 / Several stock exchanges (BM&FBOVESPA, NYSE, London Stock Exchange, among others) are expanding their offerings of socially responsible investments. One can justify this fact by increasing the demand for that type of investment. The Sustainability indexes as the ISE - Corporate Sustainability Index or DJSI - Dow Jones Sustainability Index propagate the idea that these companies that include in their business strategy, social, environmental and financial actions are better prepared for future challenges. The objective of this dissertation was to investigate whether the presence or the passage of the ISE companies can influence its value in the long run. The sample was formed by 646 firms listed on BM&FBOVESPA, obeying its classifications of economic sectors; the period considered was from 1999 to 2009, in a data panel regression. The Ohlson model (1995) was chosen for valuation of companies, because it??s a model that uses accounting variables such as book value and earnings to account for company value. The Ohlson model (1995) was validated in the statistical test, so it can explain the value of the firm for BM&FBOVESPA companies during the study period. The relationship between participating in the ISE and the company value was not statistically significant in this period. This result is contrary to the message conveyed by BM&FBOVESPA that in the long run, companies that practice Sustainability actions will generate greater value to investors. / Diversas bolsas de valores (BM&FBOVESPA, Bolsa de Nova York, Bolsa de Londres, entre outras) est??o ampliando suas ofertas de investimentos socialmente respons??veis. Pode-se justificar tal fato pelo aumento da procura desse tipo de investimento. Os ??ndices de sustentabilidade empresarial como o ISE - ??ndice de sustentabilidade empresarial ou DJSI - Dow Jones Sustainability Index propagam a id??ia de que essas empresas, que incluem na sua estrat??gia de neg??cio, a????es sociais, ambientais e financeiras, est??o melhor preparadas para os desafios futuros. O objetivo desta disserta????o foi investigar se a perman??ncia ou a passagem das empresas pelo ISE conseguem influenciar seu valor de empresa a longo prazo. A amostra foi formada pelas 646 empresas listadas na BM&FBOVESPA, obedecendo suas classifica????es dos setores econ??micos da Econom??tica; o per??odo considerado foi de 1999 a 2009; foi usada a t??cnica estat??stica de regress??o com dados em painel. Foi escolhido o modelo Ohlson (1995) para avalia????o das empresas, por ser um modelo que utiliza vari??veis cont??beis como o patrim??nio l??quido e os lucros para explicar valor de empresa. O modelo Ohlson (1995) foi validado no teste estat??stico, isto ??, ele consegue explicar o valor de empresa das empresas da BM&FBOVESPA no per??odo pesquisado. A rela????o entre participar do ISE e o valor de empresa n??o foi estatisticamente significativa, nesse per??odo. Esse resultado ?? contr??rio ?? mensagem transmitida pela BM&FBOVESPA de que, a longo prazo, as empresas que praticam a????es sustent??veis gerar??o maior valor aos investidores.
