Restri？？o financeira em empresas com a？？es negociadas na Bovespa

the paper focuses on evaluating whether brazilian publicly traded companies faced financial constraints on investments over the period 2001-2005. relying on balance-sheet and stock price data, a panel data analysis is carried out, yielding results in disagreement with the conventional literature: large firms' investments appear to be more sensitive to cash flows than smaller firms'. nonetheless, the recent literature provides some theoretical rationale as well as empirical evidence consistent with these findings.
