Investment decisions in troubled times: A Bayesian approach applied to Brazilian firms

This study analyses the investment decision of 497 Brazilian firms during a period of unstable macroeconomic conditions. The role of financial constraints is considered in a Bayesian econometric model. We estimate three different models, and the results indicate the presence of financial restrictions, especially for capital-intensive firms. The recursive predictive density criterion indicates that the most preferred model is the one in which firm-specific effects are correlated with cash-flow. Financial restrictions are more important for capital-intensive firms, probably due to their lower profitability indexes, higher fixed costs and higher degree of property diversification.
