O consumo de filmes em cinemas no Brasil: uma análise de florestas aleatórias

Abstract

também avaliamos se estes consumidores diferem significativamente dos não consumidores em suas características observáveis. Adicionalmente, num segundo estudo, usando um modelo de intervenção de Diferenças em Diferenças, investigamos o efeito da banda larga sobre o consumo de cinema. Os resultados apontam divergência clara entre os perfis de consumidores e não consumidores de filmes de cinema. . Palavras-chaves: Filmes. Cinema. Mineração de dados. Florestas aleatórias.

I investigate whether film at theaters' consumers in two distinct time are different in their observable characteristics. My investigation is based on observable variables of consumers and non-consumers data from the Family Budget Survey (POF) of 2002/2003, when the use of broadband in Brazil was almost nil, and from 2008/2009, when it already was established in the country. This change in addition to the high degree of technological changes over the period provides a window of opportunity for our objective. Although methodologically it is not possible to full isolate the effect of Internet access on film consumption, it is expected that the higher the user access speed and the greater the evolution of file compression technologies, the faster and bigger will be the traffic of films files on the web. Accordingly, the greater distribution of content on the network enables the consumption of films in alternative ways to movie theaters. Thus, in addition to identifying possible changes in the profile of movie consumers at the theaters in Brazil since the popularization of broadband in the country, which can officially be considered in the year 2006, the study assess whether these consumers differ significantly from not consumers in their observable characteristics.The results points to several distinctions between cinema consumers and no cinema consumers.
