Como as ONGs ambientais influenciam a política ambiental brasileira?

the objective of this paper is to examine how environmental ngos even with scarce resources (votes and financial contributions), succeed in influencing effectively the government's actions in brazil. the innovation is to use the common agency theory and its applications to model the environmental action in brazil. the main theoretical result is that environmental ngo's affect the environmental policy through information, revealing to voters information about government actions. the main empirical results are the measurement of rural farmers, environmental ngo's and media impacts on brazilian environmental policy.
