Deterrence mechanisms have garnered renewed interest as policy instruments to curb natural resources overexploitation. In this study deterrence is understood as inherently multidimensional, comprising the severity, celerity, and certainty of punishment. We employ an IV approach to econometrically assess the effectiveness of these dimensions in reducing deforestation in the Brazilian Savanna. The empirical results underscore the significance of severity, as well as the bureaucratic effectiveness, reflected in the certainty and celerity of enforcement, in curbing deforestation. These findings highlight the necessity of adopting a multidimensional legal and institutional framework to prevent deforestation in the region.
