Public sector transparency and countries' environmental performance: A nonparametric analysis. Resource and Energy Economics 38: 19-37

Based on the theoretical background of the link between countries’ public sector transparency and environmental policy, our paper provides empirical evidence for a sample of 49 countries for the time period of 1995–2000. Assuming that countries’ environmental performance is a product of their environmental regulations and policies, we utilize a nonparametric estimator for investigating the link with public sector's transparency levels.
