Abstract: This study estimates the determinants of the elasticities of private investment andtotal investment for the Brazilian economy for the period between 1960 and 2013. It usesa Bayesian model averaging and weighted-average least-squares approach with a flexibleaccelerator model of investment equation and Kalman filtering techniques. We concludethat the aggregate infrastructure index (taken from the main component analysis) andpublic investment crowd-in private investment. The results indicate that private investmentis constrained by the availability of bank credit. Furthermore, we find that infrastructure stock and public investment are two of the main determinants of the elasticities of privateinvestment. This demonstrates that public investment, mainly in infrastructure, is of greatimportance in raising the sensitivity of private investment in the Brazilian economy.
