Ecological footprint, public-private partnership investment in energy, and financial development in Brazil: a gradual shift causality approach

The present study assesses the effect of public-private partnerships in energy and financial development on Brazil's ecological footprint and also takes into account the role of renewable energy and economic growth using data spanning from 1983 to 2017. The study utilized several techniques including autoregressive distributive lag (ARDL) and dynamic ordinary least square (DOLS) to examine the relationship between ecological footprint and the determinants, while the gradual shift causality test was utilized to capture the causal linkage between the series in the presence of a single structural break. The outcomes of the Maki co-integration test revealed evidence of a long-run association among the variables of interest. Furthermore, the results of the ARDL and DOLS tests revealed that economic growth and public and private investment in energy increase environmental degradation, while it is mitigated by both renewable energy and financial development. Moreover, the gradual shift causality test revealed a bidirectional causal linkage between ecological footprint and economic growth. The present study recommends the establishment of a forum that will foster public and private partnerships to enhance communication, which will promote collaboration on new initiatives involving green technological innovations.

Automated summary

The study evaluates the impact of public-private partnerships on Brazil's ecological footprint in relation to energy and financial development, as well as the roles of renewable energy and economic growth. It finds that economic growth and energy investments contribute to environmental degradation, but this is offset by the effects of renewable energy and financial development. The establishment of a forum to enhance communication and collaboration in green technological innovations is recommended.
