Análise da sensibilidade do investimento em relação ao fluxo de caixa: um estudo nas empresas da indústria brasileira listadas na BM&FBOVESPA entre os anos 2004 e 2014

Abstract

Modigliani and Miller`s seminal article, published in 1958, gave great contribution to modern financial theory. The assumptions that guided this article stated that in a perfect capital market, the capital structure of the company did not interfere in its investment decision because the internal and external financing costs were perfect substitutes, as well as the fact that the company operates an investment opportunity if the rate of return on the investment is equal to or greater than the average cost of capital. Many authors, refuting the assumptions of Modigliani and Miller, and considering the existence of problems related to market imperfections and asymmetry information, now it has started to include variables in their models that capture these imperfections and demonstrated that some companies had restrictions on access to foreign credit market. Fazzari, Hubbard and Petersen (1988) are among the authors and have developed a model that aimed to demonstrate that the market imperfections could limit the gain of external funding for some companies. The results showed that there was investment sensitivity to cash flow, assuring the hypothesis of financial constraint in the companies analyzed. Due to this fact, the present research has as its goals to analyze the investment-cash flow sensitivities for Brazilian companies in the industries manufacture and extractive listed on the BM&FBOVESPA from 2004 and 2014 and the following two sub-periods of 2004 to 2008 and 2009 to 2014. To test the financial constraint hypothesis was used panel data, wherein data from the secondary system Economática were used. Thus, obtained results by the method of OLS, proved inconsistent, do not corroborate for all periods analyzed, the hypothesis defended by Fazzari, Hubbard and Petersen (1988)
