Probabilistic and Asymmetric Effects of Green Accounting on Economic Prosperity and Economic Downturns Using Bayesian Logistic Regression

Using Bayesian Logistic Regression on data from 82 countries (2002–2020), this study reveals that while green accounting generally promotes economic prosperity and mitigates downturns, its excessive expansion or severe contraction can paradoxically worsen economic declines, highlighting the need for balanced implementation.
