Public and private investments in Brazil between 1996 and 2018

ABSTRACT This work analyzes the dynamic effects generated by public investments on private investments in machinery and equipment in Brazil, between 1996 and 2018. Theories based on the principle of effective demand support the hypothesis formulated about the complementarity between public and private investments. We have developed an analytical scheme that identifies the induction channels for public investments for private ones, through demand and supply sides of the economy. From an empirical point of view, the work uses the specification of the econometric model of Autoregressive Vectors (VAR) that allows treating public investments as exogenous to the system. The results show that an increase in public investments boosts private investments during the analyzed period.
